Delivering Effective
Capital Allocation

As a management team, we are committed to being good stewards of your
capital. Our goal is to deliver Adjusted Free Cash Flow Per Share growth
of 15 – 20% compounded annually. We strive to do this by identifying high-
return growth projects while also opportunistically repurchasing our stock,
which we believe represents an investment in clean, efficient and flexible
natural gas-fired generation at attractive prices. As America moves toward
clean, affordable natural gas as the preferred fuel for power generation and
as the electric grid requires more flexible power generation to integrate inter-
mittent renewable power to assure reliability of electric supply, we believe
Calpine’s fleet is uniquely positioned to benefit from the combination of these
secular and fundamental trends that favor combined-cycle natural gas-fired
power generation as the technology of choice for America’s future.

Annual Meeting

The Annual Meeting of Shareholders of Calpine Corporation

will be held on Friday, May 10, 2013, at 8 a.m. Central Time

at our corporate offices located at 717 Texas Ave., 10th floor,

Houston, TX 77002. All shareholders are cordially invited to attend.

Forward-Looking Statement

Certain statements made in this Annual Report by or on behalf

of the Company that are not historical facts are intended to be

forward-looking statements within the meaning of the safe harbor

provisions of the Private Securities Litigation Reform Act of 1995.

These statements are based on assumptions that the Company

believes are reasonable; however, many important factors, as

discussed under “Forward-Looking Statements” in the Company’s

Form 10-K for the year ended December 31, 2012, could cause

the Company’s results in the future to differ materially from the

forward-looking statements made herein and in any other documents

or oral presentations made by or on behalf of the Company.

Our clean, efficient, modern and flexible fleet is uniquely 
positioned to benefit from these trends.  In short, Calpine 
is double-levered to economic recovery as our volume of 
electricity produced rises and electricity prices increase due 
to increasing demand and reductions in supply from retiring
coal, oil and nuclear units.

With these favorable secular trends as our backdrop, we
remain committed to further enhancing Calpine’s position as 
a leader in the industry, with particular focus on the following
management priorities.

Premier Power Generation Company

2012 was a breakout year for Calpine – our combined-cycle
plant utilization rate (known as capacity factor) was 52%, 
up nearly 23% over 2011 and the highest it has been in a
decade.  Our fleet generated a record 116 billion kWh of 
electricity, making us one of the nation’s largest suppliers 
of wholesale electricity.  Despite increased generation, we
decreased our major maintenance cost and held the line 
on operating expenses, due in large part to our continued
focus on operational excellence and preventive maintenance,
which yielded our lowest ever fleetwide forced outage factor.
Our employees achieved these accomplishments while 
continuing to demonstrate Calpine’s strong commitment 
to workplace safety.

Generation                              Forced Outage Factor

In 2012, Calpine produced approximately 116 billion kWh 
of affordable, reliable electricity for our customers, making 
us one of the nation’s largest suppliers of wholesale power.

Our pride in the Calpine team doesn’t stop at these on-the-job
feats.  We kicked off an employee wellness initiative that has
already improved the lives of our employees and the commu-
nities in which we live and operate.  Calpine’s community
involvement reached new heights last year, as we sponsored
86 cyclists in the MS150 race from Houston to Austin and 121
runners in the Houston Marathon and Half-Marathon.  When
combined with our ongoing work with holiday drives, food
banks, Earth Day, Astro’s Community Leaders and other simi-
lar efforts throughout the company, these initiatives enabled us
to contribute more than $1 million to our communities in 2012.

Our thanks and congratulations go out to the entire Calpine
team for all of these achievements.

Fellow Shareholders,

Calpine continues to capitalize
on America’s shift toward
greater utilization of
cleaner and more affordable
power generated by modern,
efficient and flexible natural
gas-fired power plants.

This secular shift represents the culmination of a series of
transformational forces that have been driving the power
generation industry for a decade:

• America stands to benefit from an abundant and affordable
supply of clean-burning, domestic natural gas as a result 
of technological advancements in drilling.  Calpine’s power 
plants are reliable and efficient and have a competitive 
cost advantage in most markets.  Meanwhile, nuclear and 
coal-fired power plants are challenged in this sustained 
low natural gas price environment. 

• America’s electricity infrastructure is old and in need of 

more than $1 trillion of new investment.  Older coal- and 
oil-fired power plants are facing retirement due to the 
prohibitive cost of required environmental upgrades, as well 
as the challenging economics of aging, inefficient plants.
• Permitting and siting issues are expensive and add signifi-

cant time to the power plant development cycle.  This 
effectively creates a barrier to entry for a number of years, 
benefiting our existing portfolio as the economy recovers. 

• Finally, as grid operators seek to integrate intermittent 
renewable power from wind and solar – especially in 
California – the flexibility of our existing power plants
should realize greater value by providing reliable, 
dispatchable electricity.

Market Advocacy

Calpine is committed to advancing the principles of competitive
wholesale power markets.  We advocate at the federal and
state levels for market-driven solutions in wholesale capacity
and energy markets that result in nondiscriminatory, transpar-
ent forward price signals in order to encourage economic
investment in affordable, flexible, clean and reliable electric
supply.  During 2012, our advocacy efforts concentrated on:
• Preserving competitive organized markets that prevent 

discrimination between new and existing generation and 
create stable pricing signals that encourage necessary 
investment

• Preventing the proliferation of subsidized generation and 

instead allowing the markets (not administrators) to select 
“winners”, and 

• Leveling the playing field between generation resources 

and demand response providers, who are currently subject 
to less stringent performance requirements yet receive 
similar compensation.

We have made progress on some fronts and while others
progress more slowly, there is momentum in the right 
direction, and we are committed to being at the forefront 
of advocacy on these issues in 2013.

Capital Allocation

We have committed to be good stewards of your capital.  
Last year, Calpine built upon its track record of effective 
capital allocation on all fronts, including asset monetization,
divestiture and acquisition, disciplined growth and share
repurchases.  Along these lines, we:

• Divested at attractive prices two power plants in South 
Carolina and Wisconsin for approximately $825 million,  
resulting in a $222 million gain 

• Acquired the 800 MW Bosque Energy Center in Texas  

for $432 million, a significant discount to replacement cost
• Advanced the construction and development of five projects
totaling approximately 1,600 MW of efficient combined-cycle 
capacity in California, Texas and Delaware, which we 
expect to come online between 2013 and 2015

• Repurchased for $600 million approximately 7.25%   

of our common stock (from November 2011 to January
2013), and

• Preserved Calpine’s financial flexibility and strength  

by maintaining a healthy balance sheet, robust liquidity  
(approximately $2.3 billion at the end of 2012) and 
minimal near-term debt maturities.

We also announced that we are targeting Adjusted Free 
Cash Flow Per Share growth of 15 – 20% compounded 
annually.  Our capital allocation decisions will be centered
around this goal.  

Looking to 2013, our efforts will remain concentrated on 
these three management priorities – continuously improving 
the premier power generation company, advancing competi-
tive electricity markets and optimizing capital allocation –
which we believe are imperative to our success.  We are
resolved to focus on what we do best, which is operating 
natural gas-fired and geothermal power plants.  In doing 
so, we will be innovative, opportunistic and nimble, and we 
will strive to maintain our competitive edge.

Thank you for your continued support of Calpine.

Sincerely,

Russell City Energy Center, California

PART I

Item 1.  Business

BUSINESS AND STRATEGY

Business

We are a premier wholesale power producer with operations throughout the U.S. We measure our success by delivering 
long-term shareholder value. We accomplish this through our focus on operational excellence, effectively executing our hedging 
strategy, our customer origination program and completing our growth capital projects on schedule and on budget. We are one of 
the  largest  power  generators  in  the  U.S.  measured  by  power  produced. We  own  and  operate  primarily  natural  gas-fired  and 
geothermal power plants in North America and have a significant presence in major competitive wholesale power markets in 
California, Texas and the Mid-Atlantic region of the U.S. Since our inception in 1984, we have been a leader in environmental 
stewardship. We have invested in clean power generation to become a recognized leader in developing, constructing, owning and 
operating an environmentally responsible portfolio of power plants. Our portfolio is primarily comprised of two types of power 
generation technologies: natural gas-fired combustion turbines, which are primarily efficient combined-cycle plants, and renewable 
geothermal conventional steam turbines. We are among the world’s largest owners and operators of industrial gas turbines as well 
as cogeneration power plants. Our Geysers Assets located in northern California represent the largest geothermal power generation 
portfolio in the U.S. and produced approximately 18% of all renewable energy in the state of California during 2011. We sell 
wholesale  power,  steam,  capacity,  renewable  energy  credits  and  ancillary  services  to  our  customers,  which  include  utilities, 
independent  electric  system  operators,  industrial  and  agricultural  companies,  retail  power  providers,  municipalities,  power 
marketers and others. We purchase natural gas and fuel oil as fuel for our power plants and engage in related natural gas transportation 
and storage transactions. We also purchase electric transmission rights to deliver power to our customers. Additionally, consistent 
with our Risk Management Policy, we enter into natural gas and power physical and financial contracts to hedge certain business 
risks and optimize our portfolio of power plants.

Our portfolio, including partnership interests, consists of 92 power plants, including 4 under construction (1 new power 
plant and 3 expansions of existing power plants), located throughout 20 states in the U.S. and Canada, with an aggregate generation 
capacity  of  27,321  MW  and  1,163  MW  under  construction.  Our  fleet,  including  projects  under  construction,  consists  of  74 
combustion turbine-based plants, 2 fossil steam-based plants, 15 geothermal turbine-based plants and 1 photovoltaic solar plant. 
In 2012, our fleet of power plants produced approximately 116 billion KWh of electric power for our customers. In addition, we 
are one of the largest consumers of natural gas in North America. In 2012, we consumed 867 Bcf or approximately 9% of the total 
estimated natural gas consumed for power generation in the U.S. We believe that having scale and geographic diversity is important 
in our business. Scale provides us the opportunity to have meaningful regulatory input, an ability to leverage our procurement 
efforts for better pricing, terms and conditions on our goods and services, and allows us to develop and offer a wide array of 
products  and  services  to  our  customers.  Geographic  diversity  helps  us  manage  weather,  regulatory  and  regional  economic 
differences across our markets.

The environmental profile of our power plants reflects our commitment to environmental leadership and stewardship. 
We have invested the necessary capital to develop a power generation portfolio that has substantially lower air pollutant emissions 
compared to our competitors’ power plants using other fossil fuels, such as coal. In addition, we strive to preserve our nation’s 
valuable water and land resources. To condense steam, our combined-cycle power plants use cooling towers with a closed water 
cooling system or air cooled condensers and do not employ “once-through” water cooling, which uses large quantities of water 
from adjacent waterways, negatively impacting aquatic life. Since our plants are modern and efficient and utilize clean burning 
natural gas, we do not require large areas of land for our power plants nor do we require large specialized landfills for the disposal 
of coal ash or nuclear plant waste. We believe that we will be less adversely impacted by Cap-and-trade limits, carbon taxes or 
required  environmental  upgrades  as  a  result  of  future  potential  regulation  or  legislation  addressing  GHG,  other  air  pollutant 
emissions such as mercury, as well as water use or emissions, compared to our competitors who use other fossil fuels or older, 
less efficient technologies.

Our principal offices are located in Houston, Texas with regional offices in Dublin, California and Wilmington, Delaware, 
an engineering, construction and maintenance services office in Pasadena, Texas and government affairs offices in Washington 
D.C., Sacramento, California and Austin, Texas. We operate our business through a variety of divisions, subsidiaries and affiliates.

Strategy

Our  goal  is  to  be  recognized  as  the  premier  wholesale  power  company  in  the  U.S.  as  measured  by  our  employees, 
shareholders, customers and regulators as well as the communities in which our facilities are located. We seek to achieve sustainable 

3

growth through financially disciplined power plant development, construction, acquisition, operation and ownership. Our strategy 
to achieve this is reflected in the four major initiatives described below:

1.  Focus on Becoming the Premier Operating Company — Our objective is to be the “best-in-class” in regards to certain 

operational performance metrics, such as safety, availability, reliability, efficiency and cost management.

•  We produced approximately 116 billion KWh of electricity in 2012, 23% more than the same period in 2011 (includes 
generation from power plants owned but not operated by us and our share of generation from our unconsolidated 
power plants).

•  Our entire fleet achieved a forced outage factor of 1.6% in 2012, our lowest on record and an improvement of 36% 

from 2011.

•  Our entire fleet achieved an impressive starting reliability of 98.3% in 2012.

•  During 2012, our outage services subsidiary completed 11 major inspections and 19 hot gas path inspections.

• 

For the past twelve consecutive years, our Geysers Assets have reliably generated approximately 6 million MWh 
per year and, in 2012, achieved an exceptional availability factor of approximately 97%.

2.  Focus on Enhancing Shareholder Value — We continue to make significant progress to deliver financially disciplined 
growth, to enhance shareholder value through our capital allocation and share repurchases and to set the foundation for 
continued growth and success. Given our strong cash flow from operations, we are committed to remaining financially 
disciplined  in  our  capital  allocation  decisions.  The  year  ended  December  31,  2012  was  marked  by  the  following 
accomplishments:

•  As of the filing of this Report, we have completed our previously announced $600 million share repurchase program, 
having repurchased a total of 35,568,833 shares of our outstanding common stock at an average price paid of $16.87 
per share. In February 2013, our Board of Directors authorized the repurchase of an additional $400 million in shares 
of our common stock, bringing the cumulative authorization total to $1.0 billion.

•  During the first quarter of 2012, we terminated our legacy interest rate swaps formerly hedging our First Lien Credit 
Facility for a payment of approximately $156 million which eliminated our exposure from these instruments to 
further declines in interest rates.

•  On October 9, 2012, we issued our 2019 First Lien Term Loan and used the proceeds to reduce our overall cost of 
debt and simplify our capital structure by redeeming a portion of our First Lien Notes and repaying project debt.

•  On November 7, 2012, we completed the purchase of a modern, natural gas-fired, combined-cycle power plant with 
a nameplate capacity of 800 MW located in Bosque County, Texas for approximately $432 million which increased 
capacity in our Texas segment.

•  On December 27, 2012, we, through our indirect, wholly-owned subsidiary Calpine Power Company, completed the 
sale of 100% of our ownership interest in each of the Broad River Entities for approximately $423 million. This 
transaction resulted in the disposition of our Broad River power plant, an 847 MW natural gas-fired, peaking power 
plant located in Gaffney, South Carolina, and includes a five year consulting agreement with the buyer. We expect 
to use the sale proceeds for our capital allocation activities and for general corporate purposes.

•  On December 31, 2012, we completed the sale of Riverside Energy Center, LLC to WP&L for approximately $402 
million. We expect to use the sale proceeds for our capital allocation activities and for general corporate purposes.

3.  Focus on Leveraging our Three Scale Regions — Our goal is to continue to grow our generation presence in core markets 
with an emphasis on expansions or modernizations of existing power plants. We intend to take advantage of favorable 
opportunities  to  continue  to  design,  develop,  acquire,  construct  and  operate  the  next  generation  of  highly  efficient, 
operationally flexible and environmentally responsible power plants where such investment meets our rigorous financial 
hurdles, particularly if power contracts and financing are available and attractive returns are expected. Likewise, we will 
actively seek divestiture opportunities on our non-core assets if those opportunities meet our financial expectations. In 
addition, we believe that modernizations and expansions to our current assets offer proven and financially disciplined 
opportunities to improve our operations, capacity and efficiencies. Our significant projects under construction, organic 
growth initiatives and modernization activities are discussed below.

West:

•  Russell City Energy Center — Construction at our Russell City Energy Center continues to move forward. Upon 
completion, this project will bring on line approximately 429 MW of net interest baseload capacity (464 MW with 
peaking capacity) representing our 75% share. Construction is ongoing and COD is expected in the summer of 2013. 
Upon completion, the Russell City Energy Center is contracted to deliver its full output to PG&E under a ten-year 
PPA.

4

• 

Los Esteros Critical Energy Facility — During 2009, we and PG&E negotiated a new PPA to replace the existing 
California  Department  of Water  Resources  contract  and  facilitate  the  modernization  of  our  Los  Esteros  Critical 
Energy Facility from a 188 MW simple-cycle generation power plant to a 309 MW combined-cycle generation power 
plant, which will also increase the efficiency and environmental performance of the power plant by lowering the 
Heat Rate. Construction is ongoing and COD is expected in the summer of 2013.

Texas:

•  Channel and Deer Park Expansions — In September and November 2011, we filed air permit applications with the 
TCEQ and the EPA to expand the baseload capacity of the Deer Park and Channel Energy Centers by approximately 
260 MW each. We received air permit approvals from the TCEQ for our Deer Park and Channel expansion projects 
in September and October 2012, respectively, and from the EPA in November 2012. Construction on these expansion 
projects commenced in the fourth quarter of 2012. We expect COD during the summer of 2014 for these expansions 
and are currently evaluating funding sources including, but not limited to, nonrecourse financing, corporate financing 
or internally generated funds.

North:

•  Garrison Energy Center — We are actively permitting 618 MW of new combined-cycle capacity at a development 
site  secured  by  a  long-term  lease  with  the  City  of  Dover.  For  the  first  phase  (309  MW),  we  have  executed  the 
Interconnection Services Agreement and the Interconnection Construction Services Agreement with PJM. For the 
second phase (309 MW), we have completed a feasibility study and are currently conducting a system impact study. 
Environmental permitting, site development planning and development engineering are underway and the first phase’s 
capacity cleared PJM’s 2015/2016 base residual auction. We received the air permit and executed a preliminary 
notice to proceed for the engineering, procurement and construction agreement during the first quarter of 2013. We 
expect COD for the first phase by the summer of 2015 and are currently evaluating funding sources including, but 
not limited to, nonrecourse financing, corporate financing or internally generated funds. 

All Segments:

• 

Turbine Modernization — We continue to move forward with our turbine modernization program. Through December 
31, 2012, we have completed the upgrade of eleven Siemens and eight GE turbines totaling over 200 MW and have 
committed to upgrade approximately three additional turbines.

4.  Focus on Customer-Oriented Origination Business — We continue to focus on providing products and services that are 

beneficial to our customers. A summary of certain significant contracts entered into or approved in 2012 is as follows:

•  We entered into a new twenty-year PPA with Western Farmers Electric Cooperative to provide 160 MW of power 
generated by our Oneta Energy Center, commencing in June 2014. The capacity under contract will increase in 
increments, up to a maximum of 280 MW in years 2019 through 2035.

•  We entered into a new five-year PPA with Southwestern Public Service Company, a subsidiary of Xcel Energy, to 
provide an additional 200 MW of power generated by our Oneta Energy Center commencing on June 1, 2014.

•  We entered into a new five-year resource adequacy contract with PG&E for approximately 280 MW of combined 

heat and power capacity from our Los Medanos Energy Center commencing in the summer 2013.

•  We entered into a new seven-year resource adequacy contract with Southern California Edison Company (“SCE”) 
for approximately 280 MW of combined heat and power capacity from our Los Medanos Energy Center and a new 
five-year resource adequacy contract with SCE for approximately 120 MW of combined heat and power capacity 
from our Gilroy Cogeneration Plant, both commencing in January 2014.

•  We amended an existing PPA with Dow Chemical Company for an incremental energy sale of up to approximately 

158,000 MWh per year of energy from our Los Medanos Energy Center which runs through February 2025.

•  We entered into a new fifteen-year PPA with American Electric Power Service Corporation, as agent for Public 
Service Company of Oklahoma, to provide 260 MW of energy, capacity and ancillary services from our Oneta Energy 
Center commencing in June 2016.

•  We entered into a new ten-year PPA with the Tennessee Valley Authority to provide the full output of power generated 
by our Decatur Energy Center, a natural gas-fired, combined-cycle power plant that can generate up to 795 MW, 
commencing in January 2013.

THE MARKET FOR POWER

Our Power Markets and Market Fundamentals

The power industry represents one of the largest industries in the U.S. and impacts nearly every aspect of our economy, 
with  an  estimated  end-user  market  of  approximately  $364  billion  in  power  sales  in  2012  according  to  the  EIA.  Historically, 
vertically integrated power utilities with monopolies over franchised territories dominated the power generation industry in the 
U.S. Over the last 25 years, industry trends and regulatory initiatives, culminating with the deregulation trend of the late 1990’s 
and early 2000’s, provided opportunities for wholesale power producers to compete to provide power. Although different regions 
of the country have very different models and rules for competition, the markets in which we operate have some form of wholesale 
market competition. California (included in our West segment), Texas and the Mid-Atlantic (included in our North segment), 
which are the markets in which we have our largest presence, have emerged as among the most competitive wholesale power 
markets in the U.S. We also operate, to a lesser extent, in the competitive ISO-NE, NYISO and MISO markets. We produce several 
products for sale to our customers.

First, we are a wholesale provider of power to utilities, independent electric system operators, industrial or agricultural 
companies, retail power providers, municipalities, and power marketers. Our power sales occur in several different 
product  categories  including  baseload  (around  the  clock  generation),  intermediate  (generation  typically  more 
expensive than baseload and utilized during higher demand periods to meet shifting demand needs), and peaking 
capacity (most expensive variable cost and utilized during the highest demand periods), for which the latter is provided 
by  some  of  our  stand-alone  peaking  power  plants/units  and  from  our  combined-cycle  power  plants  by  using 
technologies such as steam injection or duct firing additional burners in the heat recovery steam generators. Many 
of our units have operated more frequently as baseload units at times when low natural gas prices have driven their 
production costs below those of some competing coal-fired units.

Second, we provide capacity for sale to retail power providers. In various markets, retail power providers are required 
to demonstrate adequate resources to meet their power sales commitments. To meet this obligation, they procure a 
market product known as capacity from power plant owners or resellers. Most electricity market administrators have 
acknowledged that an energy only market does not provide sufficient revenues to enable existing merchant generators 
to recover all of their costs or to encourage the construction of new power plants. Capacity auctions have been 
implemented in the northeast, the Mid-Atlantic and some midwest regional markets to address this issue. California 
has a bilateral capacity program. Texas does not presently have a capacity market, nor a requirement for retailers to 
ensure adequate resources.

Third, we sell RECs from our Geysers Assets in northern California, as well as from our small solar power plant in 
New Jersey. California has an RPS that requires load serving entities to have RECs for a certain percentage of their 
demand for the purpose of guaranteeing a certain level of renewable generation in the state. Because geothermal is 
a renewable source of energy, we receive a REC for each MWh we produce and are able to sell our RECs to load 
serving entities. New Jersey has a solar specific RPS which enables us to sell RECs from our Vineland Solar Energy 
Center.

Fourth, our cogeneration power plants produce steam for sale to customers for use in industrial or heating, ventilation 
and air conditioning operations.

Fifth, we provide ancillary service products to wholesale power markets. These products include the right for the 
purchaser to call on our generation to provide flexibility to the market and support operation of the electric grid. As 
an example, we are sometimes paid to reserve a portion of capacity at some of our power plants that could be deployed 
quickly should there be an unexpected increase in load or to assure reliability due to fluctuations in the supply of 
power  from  variable  renewable  resources  such  as  wind  and  solar  generation. These  ramping  characteristics  are 
becoming increasingly necessary in markets where intermittent renewables have large penetrations.

In addition to the five products above, we are buyers and sellers of environmental allowances and credits, including those 
under RGGI, the federal Acid Rain and CAIR programs and emission reduction credits under the federal Nonattainment New 
Source Review program. We also participate in CO2 emissions credit markets related to California’s AB 32 GHG reduction program.

Although all of the products mentioned above contribute to our financial performance and are the primary components 
of our Commodity Margin, the most important is our sale of wholesale power. We utilize long-term customer contracts for our 
power and steam sales where possible. For power that is not sold under customer contracts, we use our hedging program throughout 
the markets in which we participate.

For sales of power from our natural gas-fired fleet into the short-term or spot markets, we attempt to maximize our 
operations  when  the  market  Spark  Spread  is  positive. Assuming  economic  behavior  by  market  participants,  generating  units 
generally are dispatched in order of their variable costs, with lower cost units being dispatched first and units with higher costs 
dispatched as demand, or “load,” grows beyond the capacity of the lower cost units. For this reason, in a competitive market, the 
price of power typically is related to the variable operating costs of the marginal generator, which is the last unit to be dispatched 
in order to meet demand. The market factors that most significantly impact our operations are reserve margins, the price and supply 
of natural gas and competing fuels such as coal and oil, weather patterns and natural events, our operating Heat Rate, availability 
factors, and regulatory and environmental pressures as further discussed below.

Reserve Margins

Reserve margin, a measure of excess generation capacity in a market, is a key indicator of the competitive conditions in 
the markets in which we operate. For example, a reserve margin of 15% indicates that supply is 115% of expected peak power 
demand under normal weather conditions. Holding other factors constant, lower reserve margins typically lead to higher power 
prices because the less efficient capacity in the region is needed more often to satisfy power demand or voluntary or involuntary 
load shedding measures are taken. Markets with tight demand and supply conditions often display price spikes and improved 
bilateral contracting opportunities. Typically, the market price impact of reserve margins, as well as other supply/demand factors, 
is reflected in the Market Heat Rate, calculated as the local market power price divided by the local natural gas price.

During the last decade, the supply and demand fundamentals in many regional markets have been negatively impacted 
by the combination of new generation coming on line and a general decline in weather normalized load growth rates due to the 
economic recession. Although uncertainty exists and there are key regional differences at a macro level, continued economic 
recovery and thus, corresponding load recovery, with the lack of broad new power plant investments in our key markets should 
lead to lower reserve margins and higher Market Heat Rates. Reserve margins by NERC regional assessment area for each of our 
segments are listed below:

The Price and Supply of Natural Gas

Approximately 95% of our generating capability’s fuel requirements are met with natural gas. We have approximately 
725 MW of baseload capacity from our Geysers Assets and our expectation is that the steam reservoir at our Geysers Assets will 
be able to supply economic quantities of steam for the foreseeable future as our steam flow decline rates have become very small 
over the past several years. We also have approximately 596 MW of capacity from power plants where we purchase fuel oil to 
meet these generation requirements, but do not expect fuel oil requirements to be material to our portfolio of power plant assets. 
Additionally, we have 4 MW of capacity from solar power generation technology with no fuel requirement.

We procure natural gas from multiple suppliers and transportation and storage sources. Although availability is generally 
not an issue, localized shortages (especially in extreme weather conditions in and around the population centers), transportation 
availability and supplier financial stability issues can and do occur.

Lower gas prices over the past four years have had a significant impact on power markets. Beginning in 2009, there was 
a significant decrease in NYMEX Henry Hub natural gas prices from a range of $6/MMBtu — $13/MMBtu during 2008 to an 

7

 
average natural gas price of $4.38/MMBtu, $4.03/MMBtu, and $2.83/MMBtu during 2010, 2011 and 2012, respectively. Natural 
gas prices in some parts of the country for parts of 2010, 2011 and 2012 were low enough that modern, combined-cycle, natural 
gas-fired generation became less expensive on a marginal basis than coal-fired generation. The result was that natural gas displaced 
coal as a less expensive generation resource resulting in what the industry describes as coal-to-gas switching, the effects of which 
can be seen in our increased generation volumes in 2012. 

The availability of non-conventional natural gas supplies, in particular shale natural gas, has been the primary driver of 
reduced natural gas prices in the last few years. Access to significant deposits of shale natural gas has altered the natural gas supply 
landscape in the U.S. and could have a longer-term and profound impact on both the outright price of natural gas and the historical 
regional  natural  gas  price  relationships  (basis  differentials). The  U.S.  Department  of  Energy  estimates  that  shale  natural  gas 
production has the potential of 3 trillion to 4 trillion cubic feet per year and may be sustainable for decades with enough natural 
gas to supply the U.S. for the next 90 years. Accordingly, there is an emerging view that lower priced natural gas will be available 
for the medium to long-term future. 

The price of natural gas, economic growth and environmental regulations affect our Commodity Margin and liquidity. 
The impact of changes in natural gas prices differs according to the time horizon and regional market conditions and depends on 
our hedge levels and other factors discussed below.

Much of our generating capacity is located in California (included in our West segment), Texas and the Mid-Atlantic 
(included in our North segment) where natural gas-fired units set power prices during many hours. When natural gas is the price-
setting fuel, increases in natural gas prices may increase our unhedged Commodity Margin because our combined-cycle power 
plants  in  those  markets  are  more  fuel-efficient  than  conventional  natural  gas-fired  technologies  and  peaking  power  plants. 
Conversely,  decreases  in  natural  gas  prices  may  decrease  our  unhedged  Commodity  Margin.  In  these  instances,  our  cost  of 
production advantage relative to less efficient natural gas-fired generation is diminished on an absolute basis.

In 2012, given very low natural gas prices, natural gas-fired, combined-cycle units in many markets were frequently 
cheaper to dispatch than coal-fired power plants. When coal-fired electricity production costs exceed natural gas-fired production 
costs, coal-fired units tend to set power prices. In these hours, lower natural gas prices tend to increase our Commodity Margin, 
since our production costs fall while power prices remain constant (depending on our hedge levels and holding other factors 
constant).

Where we operate under long-term contracts, changes in natural gas prices can have a neutral impact on us in the short-
term. This tends to be the case where we have entered into tolling agreements under which the customer provides the natural gas 
and we convert it to power for a fee, or where we enter into indexed-based agreements with a contractual Heat Rate at or near our 
actual Heat Rate for a monthly payment.

Changes in natural gas prices or power prices may also affect our liquidity. During periods of high or volatile natural gas 

prices, we could be required to post additional cash collateral or letters of credit.

Despite these short-term dynamics, over the long-term, we expect lower natural gas prices to encourage new combined-
cycle gas turbine power plant investment, thus enhancing the competitiveness of our modern, natural gas-fired fleet by making 
investment in other technologies such as coal, nuclear, or renewables less economic.

Weather Patterns and Natural Events

Weather generally has a significant short-term impact on supply and demand for power and natural gas. Historically, 
demand for and the price of power is higher in the summer and winter seasons when temperatures are more extreme, and therefore, 
our  unhedged  revenues  and  Commodity  Margin  could  be  negatively  impacted  by  relatively  cool  summers  or  mild  winters. 
Additionally, a disproportionate amount of our total revenue is usually realized during the summer months of our third fiscal 
quarter. We expect this trend to continue in the future as U.S. demand for power generally peaks during this time.

Operating Heat Rate and Availability

Our fleet is modern and more efficient than the average generation fleet; accordingly, we run more and earn incremental 
margin in markets where less efficient natural gas units frequently set the power price. In such cases, our unhedged Commodity 
Margin is positively correlated with how much more efficient our fleet is than our competitors’ fleets and with higher natural gas 
prices. Efficient operation of our fleet creates the opportunity to capture Commodity Margin. However, unplanned outages during 
periods when Commodity Margin is positive can result in a loss of that opportunity. We measure our fleet performance based on 
our operating Heat Rate and availability factors. The higher our availability factor, the better positioned we are to capture Commodity 
Margin. The lower our operating Heat Rate compared to the Market Heat Rate, the more favorable the impact on our Commodity 
Margin.

Regulatory and Environmental Pressures

We believe that, on a net basis, we will be favorably impacted by current regulatory and environmental trends, including 

those described below, given the characteristics of our power plant portfolio:

•  Environmental pressures continue to increase for coal-fired power generation as state and federal agencies enact 
rules to reduce air emissions of certain pollutants such as SO2, NOX, GHG, Hg and acid gases, restrict the use of 
once-through cooling, and provide for stricter standards for managing coal combustion residuals. Some of the regions 
in which we operate include older, less efficient fossil-fuel power plants that emit much higher amounts of GHG, 
SO2, NOX, Hg and acid gases, which we anticipate will be negatively impacted by current and future air emissions, 
water and waste regulations and legislation both at the state and federal levels. The estimated capacity for fossil-
fueled plants which are older than 50 years and the total estimated capacity for fossil-fueled plants by NERC region 
are as follows:

•  An increase in power generated from renewable sources could lead to an increased need for flexible power that many 
of our power plants provide to protect the reliability of the grid and premium compensation for that flexibility; 
however, risks also exist that renewables have the ability to lower overall wholesale prices which could negatively 
impact us. Significant economic and reliability concerns for renewable generation have been raised, but we expect 
that renewable market penetration will continue to be assisted by state-level renewable portfolio standards and federal 
tax incentives.

•  The regulators in our core markets remain committed to the competitive wholesale power model, particularly in 
Texas and PJM where they continue to focus on market design and rules to assure the long-term viability of competition 
and the benefits to customers that justify competition.

•  Utilities are increasingly focused on demand side management – managing the level and timing of power usage 
through  load  curtailment,  dispatching  generators  located  at  commercial  or  industrial  sites,  and  “smart  grid” 
technologies that may improve the efficiencies, dispatch usage and reliability of electric grids. Scrutiny of demand 
side resources has increased in recent months as system operators evaluate their reliability (especially at high levels 
of penetration) and environmental authorities deal with the implications of relying on smaller, less environmentally 
efficient generation sources during periods of peak demand when air quality is already challenged.

•  Environmental  permitting  requirements  for  new  power  plants  and  transmission  lines  are  becoming  increasingly 

onerous.

We believe these trends are positive for our fleet. For a discussion of federal, state and regional legislative and regulatory 

initiatives and how they might affect us, see “— Governmental and Regulatory Matters.”

It is very difficult to predict the continued evolution of our markets due to the uncertainty of the following:

• 

• 

number of market participants, both in terms of physical presence as well as contribution toward financial market 
liquidity;

amount of power available in the market;

interruptions in natural gas transportation;

relative ease or difficulty of developing, permitting and constructing new power plants;

creditworthiness and other risks associated with counterparties;

bidding behavior of market participants;

regulatory and ISO guidelines and rules;

structure of commercial products; and

ability to optimize the market’s mix of alternative sources of power such as renewable and hydroelectric power.

Competition

Wholesale power generation is a capital-intensive, commodity-driven business with numerous industry participants. We 
compete against other independent power producers, power marketers and trading companies, including those owned by financial 
institutions, retail load aggregators, municipalities, retail power providers, cooperatives and regulated utilities to supply power 
and power-related products to our customers in major markets in the U.S. and Canada. In addition, in some markets, we compete 
against some of our customers.

In markets with centralized ISOs, such as California, Texas and the Mid-Atlantic, our natural gas-fired power plants 
compete directly with all other sources of power. The EIA estimates that in 2012, 30% of the power generated in the U.S. was 
fueled by natural gas and that approximately 56% of power generated in the U.S. was produced by coal and nuclear facilities, 
which generated approximately 37% and 19%, respectively. The EIA estimates that the remaining 14% of power generated in the 
U.S. was fueled by hydroelectric, fuel oil and other energy sources. We are subject to complex and stringent energy, environmental 
and other governmental laws and regulations at the federal, state and local levels in connection with the development, ownership 
and operation of our power plants. Federal and state legislative and regulatory actions continue to change. The federal government 
is continuing to take further action on many air pollutant emissions such as NOX, SO2, Hg and acid gases as well as on once-
through cooling and coal ash disposal. Although we cannot predict the ultimate effect any future environmental legislation or 
regulations will have on our business, as a clean energy provider, we believe that we are well positioned for almost any increase 
in environmental rule stringency. We are actively participating in these debates at the federal, regional and state levels. For a further 
discussion of the environmental and other governmental regulations that affect us, see “— Governmental and Regulatory Matters.”

With new environmental regulations, the proportion of power generated by natural gas and other low emissions resources 
is expected to increase because older coal-fired power plants will be required to install costly emissions control devices, limit their 
operations or be retired. Meanwhile, the federal government and many states are considering or have already mandated that certain 
percentages of power delivered to end users in their jurisdictions be produced from renewable resources, such as geothermal, wind 
and solar energy.

Competition from other sources of power, such as nuclear energy and renewables, could increase in the future, but likely 
at a lower rate than had been previously expected. The nuclear incident in March 2011 at the Fukushima Daiichi nuclear power 
plant introduced substantial uncertainties around new nuclear power plant development in the U.S. In addition, the combination 
of emerging air emissions regulations, federal and state financial incentives and RPS requirements for renewables and their impact 
of expected increased investment in cleaner sources of generation will be somewhat counteracted by a lower natural gas price 
environment, which, should it persist, makes new investment in these types of power generation generally uneconomical. Thus, 
it is doubtful that generation from new nuclear power plants and renewable sources will be available in the quantities needed to 
meet  future  energy  demand.  Beyond  economic  issues,  there  are  concerns  over  the  reliability  and  adequacy  of  transmission 
infrastructure to transmit certain renewable generation from its source to where it is needed. Consequently, long-term, natural gas 
units are likely still needed as baseload and “back-up” generation.

We believe our ability to compete will be driven by the extent to which we are able to accomplish the following:

• 

provide affordable, reliable services to our customers;

•  maintain excellence in operations;

• 

achieve and maintain a lower cost of production, primarily by maintaining unit availability and efficiency;

10

• 

• 

accurately assess and effectively manage our risks; and

benefit from future environmental regulation and legislation.

MARKETING, HEDGING AND OPTIMIZATION ACTIVITIES

Our commercial hedging and optimization strategies are designed to maximize our risk-adjusted Commodity Margin by 
leveraging our knowledge, experience and fundamental views on natural gas and power. Additionally, we seek strong bilateral 
relationships with load serving entities that can benefit us and our customers.

The majority of our risk exposures arise from our ownership and operation of power plants. Our primary risk exposures 
are Spark Spread, power prices, natural gas prices, capacity prices, locational price differences in both power and natural gas, 
natural gas transportation, electric transmission, REC prices, carbon prices in California and other emissions credit prices. In 
addition to the direct risk exposure to commodity prices, we also have general market risks such as risk related to performance of 
our counterparties and customers and plant operating performance risk. We also have a small exposure to Canadian exchange rates 
due to our partial ownership of Greenfield LP and Whitby located in Canada, which are under long term contracts, and minimal 
fuel oil exposure which are not currently material to our operations. As such, we have currently elected not to hedge our Canadian 
exchange rate or fuel oil exposure.

We produced approximately 116 billion KWh of electricity in 2012 across North America (primarily in the U.S.). We 
are one of the largest consumers of natural gas in North America having consumed approximately 867 Bcf during 2012. The four 
primary power markets in which we conduct our operations are Texas, California, PJM and the Southeast. The Texas, California 
and PJM markets have a centralized market for which power demand and prices are determined on a spot basis (day ahead and 
real time), and the Southeast market is a bilateral market. Most of the power generated by our power plants is sold to entities such 
as independent electric system operators, utilities, municipalities and cooperatives, as well as to retail power providers, commercial 
and industrial end users, financial institutions, power trading and marketing companies and other third parties.

We actively manage our risk exposures with a variety of physical and financial instruments with varying time horizons. 
These instruments include PPAs, tolling arrangements, Heat Rate swaps and options, load sales, steam sales, buying and selling 
standard physical products, buying and selling exchange traded instruments, gas transportation and storage arrangements, electric 
transmission service and other contracts for the sale and purchase of power products. We utilize these instruments to maximize 
the risk-adjusted returns for our Commodity Margin.

At any point in time, the relative quantity of our products hedged or sold under longer-term contracts is determined by 
the availability of forward product sales opportunities and our view of the attractiveness of the pricing available for forward sales.  
Historically, we have economically hedged a portion of our expected generation and natural gas portfolio mostly through power 
and  natural  gas  forward  physical  and  financial  transactions;  however,  we  currently  remain  susceptible  to  significant  price 
movements for 2013 and beyond. When we elect to enter into these transactions, we are able to economically hedge a portion of 
our Spark Spread at pre-determined generation and price levels. 

We conduct our hedging and optimization activities within a structured risk management framework based on controls, 
policies and procedures. We monitor these activities through active and ongoing management and oversight, defined roles and 
responsibilities,  and  daily  risk  measurement  and  reporting.  Additionally,  we  seek  to  manage  the  associated  risks  through 
diversification, by controlling position sizes, by using portfolio position limits, and by entering into offsetting positions that lock 
in a margin. We also are exposed to commodity price movements (both profits and losses) in connection with these transactions. 
These positions are included in and subject to our consolidated risk management portfolio position limits and controls structure. 
Our future hedged status and marketing and optimization activities are subject to change as determined by our commercial operations 
group, Chief Risk Officer, senior management and Board of Directors. For control purposes, we have VAR limits that govern the 
overall risk of our portfolio of power plants, energy contracts, financial hedging transactions and other contracts. Our VAR limits, 
transaction approval limits and other risk related controls, are dictated by our Risk Management Policy which is approved by our 
Board of Directors and by a committee comprised of members of our senior management and administered by our Chief Risk 
Officer's organization. The Chief Risk Officer's organization is segregated from the commercial operations unit and reports directly 
to our Audit Committee and Chief Financial Officer. Our Risk Management Policy is primarily designed to provide us with a 
degree of protection from significant downside commodity price risk exposure to our cash flows.

In order to simplify our reporting, we elected to discontinue the application of hedge accounting treatment during the 
first quarter of 2012 for all commodity derivatives, including the remaining commodity derivatives previously accounted for as 
cash flow hedges. Accordingly, prospective changes in fair value from the date of this election are reflected in unrealized mark-
to-market activity on our Consolidated Statements of Operations and could create more volatility in our earnings. The fair value 
of our commodity derivative instruments residing in AOCI during the previous application of hedge accounting was reclassified 

11

to earnings during 2012 as the related economic transactions affected earnings or the forecasted transaction became probable of 
not occurring. 

We have historically used interest rate swaps to adjust the mix between our fixed and variable rate debt. To the extent 
eligible, our interest rate swaps have been designated as cash flow hedges, and changes in fair value are recorded in OCI to the 
extent they are effective with gains and losses reclassified into earnings in the same period during which the hedged forecasted 
transaction affects earnings. The reclassification of unrealized losses from AOCI into earnings and the changes in fair value and 
settlements subsequent to the reclassification date of the interest rate swaps formerly hedging our First Lien Credit Facility is 
presented separately from interest expense as loss on interest rate derivatives on our Consolidated Statements of Operations. See 
Note 8 of the Notes to Consolidated Financial Statements for further discussion of our derivative instruments.

Seasonality and weather can have a significant impact on our results of operations and are also considered in our hedging 
and optimization activities. Most of our power plants are located in regional power markets where the greatest demand for power 
occurs during the summer months, which coincides with our third fiscal quarter. Depending on existing contract obligations and 
forecasted weather and power demands, we may maintain either a larger or smaller open position on fuel supply and committed 
generation during the summer months in order to protect and enhance our Commodity Margin accordingly.

Power Plants in Operation at December 31, 2012

We own 92 power plants, including 4 under construction (1 new power plant and 3 expansions of existing power plants), 

with an aggregate generation capacity of approximately 27,321 MW and 1,163 MW under construction.

Natural Gas-Fired Fleet

Our natural gas-fired power plants primarily utilize two types of designs: 2,465 MW of simple-cycle combustion turbines 
and 23,244 MW of combined-cycle combustion turbines and a small portion from conventional natural gas/oil-fired boilers with 
steam turbines. Simple-cycle combustion turbines burn natural gas or oil to spin an electric generator to produce power. A combined-
cycle unit combusts fuel like a simple-cycle combustion turbine and the exhaust heat is captured by a heat recovery boiler to create 
steam which can then spin a steam turbine. Simple-cycle turbines are easier to maintain, but combined-cycle turbines operate with 
much higher efficiency. Our “all in” Steam Adjusted Heat Rate for 2012 for the power plants we operate was 7,361 Btu/KWh 
which results in a power conversion efficiency of approximately 46%. The power conversion efficiency is a measure of how 
efficiently a fossil fuel power plant converts thermal energy to electrical energy. Our “all in” Steam Adjusted Heat Rate includes 
all fuel required to dispatch our power plants including “start-up” and “shut-down” fuel, as well as all non-steady state operations. 
Once our power plants achieve steady state operations, our combined-cycle power plants achieve an average power conversion 
efficiency of approximately 50%. Additionally, we also sell steam from our combined heat and power plants, which improves our 
power conversion efficiency in steady state operations from these power plants to an average of approximately 53%. Due to our 
modern combustion turbine fleet, our power conversion efficiency is significantly better than that of older technology natural gas-
fired power plants and coal-fired power plants, which typically have power conversion efficiencies that range from 28% to 36%.

Each of our power plants currently in operation is capable of producing power for sale to a utility, another third-party 
end user or an intermediary such as a marketing company. At 19 of our power plants we also produce thermal energy (primarily 
steam and chilled water), which can be sold to industrial and governmental users. These plants are called combined heat and power 
facilities.

Our  natural  gas  fleet  is  relatively  young  with  a  weighted  average  age,  based  upon  MW  capacities  in  operation,  of 
approximately thirteen years. Taken as a portfolio, our natural gas power plants are among the most efficient in converting natural 
gas to power and emit far fewer pollutants than most typical utility fleets. The age, scale, efficiency and cleanliness of our power 
plants is a unique profile in the wholesale power sector.

The majority of the combustion turbines in our fleet are one of four technologies: GE 7FA, GE LM6000, Siemens 501FD 
or Siemens V84.2 turbines. We maintain our fleet through a regular and rigorous maintenance program. As units reach certain 
operating targets, which are typically based upon service hours or number of starts, we perform the maintenance that is required 
for that unit at that stage in its life cycle. Our large fleet of similar technologies has enabled us to build significant technical and 
engineering experience with these units and minimize the number of replacement parts in inventory. We leverage this experience 
by performing much of our major maintenance ourselves with our outage services subsidiary.

Geothermal Fleet

Our  Geysers Assets  are  a  725 MW  fleet  of  15  operating  power  plants  in  northern  California.  Geothermal  power  is 
considered a renewable energy because the steam harnessed to power our turbines is produced inside the Earth and does not require 
burning fuel. The steam is produced below the Earth’s surface from reservoirs of hot water, both naturally occurring and injected. 
The steam is piped directly from the underground production wells to the power plants and used to spin turbines to make power. 
For the past twelve consecutive years, our Geysers Assets have continued to generate approximately 6 million MWh per year. 
Unlike other renewable resources such as wind or sunlight, which depend on intermittent sources to generate power, making them 
less reliable, geothermal power provides a consistent source of energy as evidenced by our Geysers Assets’ availability record of 
approximately 97% in 2012.

We inject water back into the steam reservoir, which extends the useful life of the resource and helps to maintain the 
output of our Geysers Assets. The water we inject comes from the condensate associated with the steam extracted to generate 
power,  wells  and  creeks,  as  well  as  water  purchase  agreements  for  reclaimed  water.  We  receive  and  inject  an  average  of 
approximately 16 million gallons of reclaimed water per day into the geothermal steam reservoir at The Geysers where the water 
is naturally heated by the Earth, creating additional steam to fuel our Geysers Assets. Approximately 12 million gallons per day 
are received from the Santa Rosa Geysers Recharge Project, which we developed jointly with the City of Santa Rosa, and we 
receive, on average, approximately 4 million gallons a day from The Lake County Recharge Project from Lake County. As a result 
of these recharge projects, MWh production has been relatively constant. We expect that, as a result of the water injection program, 
the reservoir at our Geysers Assets will be able to supply economic quantities of steam for the foreseeable future.

We periodically review our geothermal studies to help us assess the economic life of our geothermal reserves. Our most 
recent geothermal reserve study was conducted in 2011. Our evaluation of our geothermal reserves, including our review of any 
applicable independent studies conducted, indicates that our Geysers Assets should continue to supply sufficient steam to generate 
positive cash flows at least through 2068. In reaching this conclusion, our evaluation, consistent with the due diligence study of 
2011, assumes that defined “proved reserves” are those quantities of geothermal energy which, by analysis of geological and 
engineering data, can be estimated with reasonable certainty to be commercially recoverable, from a given date forward, from 
known reservoirs and under current economic conditions, operating methods, and government regulations.

We lease the geothermal steam fields from which we extract steam for our Geysers Assets. We have leasehold mineral 
interests in 110 leases comprising approximately 29,019 acres of federal, state and private geothermal resource lands in The Geysers 
region of northern California. Our leases cover one contiguous area of property that comprises approximately 45 square miles in 
the northwest corner of Sonoma County and southeast corner of Lake County. The approximate breakout by volume of steam 
removed under the above leases for the year ended 2012 is:

• 

• 

• 

29% related to leases with the federal government via the Office of Natural Resources Revenue (formerly, the Minerals 
Management Service),

28% related to leases with the California State Lands Commission, and

43% related to leases with private landowners/leaseholders.

In general, our geothermal leases grant us the exclusive right to drill for, produce and sell geothermal resources from 
these properties and the right to use the surface for all related purposes. Each lease requires the payment of annual rent until 
commercial quantities of geothermal resources are established. After such time, the leases require the payment of minimum advance 
royalties or other payments until production commences, at which time production royalties are payable on a monthly basis from 
10 to 31 days (depending upon the lease terms) following the close of the production month. Such royalties and other payments 
are payable to landowners, state and federal agencies and others, and vary widely as to the particular lease. In general, royalties 
payable are calculated based upon a percentage of total gross revenue received by us associated with our geothermal leases. Each 
lease’s royalty calculation is based upon its percentage of revenue as calculated by its steam generated to the total steam generated 
by our Geysers Assets as a whole.

Our geothermal leases are generally for initial terms varying from 10 to 20 years or for so long as geothermal resources 
are produced and sold. A few of our geothermal leases were signed in excess of 30 years ago. Our federal leases are, in general, 
for an initial 10-year period with renewal clauses for an additional 40 years for a maximum of 50 years. The 50-year term expires 
in 2024 for the majority of our federal leases. However, our federal leases allow for a preferential right to renewal for a second 
40-year term on such terms and conditions as the lessor deems appropriate if, at the end of the initial 40-year term, geothermal 
steam is being produced or utilized in commercial quantities. The majority of our other leases run through the economic life of 
our Geysers Assets and provide for renewals so long as geothermal resources are being produced or utilized, or are capable of 
being produced or utilized, in commercial quantities from the leased land or from land unitized with the leased land. Although we 
believe that we will be able to renew our leases through the economic life of our Geysers Assets on terms that are acceptable to 
us, it is possible that certain of our leases may not be renewed, or may be renewable only on less favorable terms.

In addition, we hold 40 geothermal leases comprising approximately 43,840 acres of federal geothermal resource lands 
in the Glass Mountain area in northern California, which is separate from The Geysers region. Four test production wells were 
drilled prior to our acquisition of these leases and we have drilled one test well since their acquisition, which produced commercial 
quantities of steam during flow tests. However, the properties subject to these leases have not been developed and there can be 
no assurance that these leases will ultimately be developed.

Other Power Generation Technologies

Across the fleet, we also have a variety of older, less efficient technologies including approximately 883 MW of capacity 
from power plants which have conventional steam turbine technology. We also have approximately 4 MW of capacity from solar 
power generation technology at our Vineland Solar Energy Center in New Jersey.

(1)  Natural gas-fired fleet capacities are generally derived on as-built as-designed outputs, including upgrades, based on site 
specific  annual  average  temperatures  and  average  process  steam  flows  for  cogeneration  power  plants,  as  applicable. 
Geothermal capacities are derived from historical generation output and steam reservoir modeling under average ambient 
conditions (temperatures and rainfall).

(2)  Natural gas-fired fleet peaking capacities are primarily derived on as-built as-designed peaking outputs based on site specific 
average summer temperatures and include power enhancement features such as heat recovery steam generator duct-firing, 
gas  turbine  power  augmentation,  and/or  other  power  augmentation  features.  For  certain  power  plants  with  definitive 
contracts, capacities at contract conditions have been included. Oil-fired capacities reflect capacity test results.

(3) 

These outputs do not factor in the typical MW loss and recovery profiles over time, which natural gas-fired turbine power 
plants display associated with their planned major maintenance schedules.

(4)  MWh generation is shown here as our net operating interest.

(5) 

Pasadena is comprised of 260 MW of cogen technology and 521 MW of combined cycle (non-cogen) technology.

(6)  Bosque Energy Center was acquired on November 7, 2012.

(7) 

Freeport Energy Center is owned by Calpine; however, it is contracted and operated by The Dow Chemical Company.

(8)  Calpine holds a 50% partnership interest in Greenfield LP through its subsidiaries; however, it is operated by a third party.

(9)  We have provided notice to PJM that we plan to retire these units before commencement of the PJM Reliability Pricing 

Model 2015/2016 delivery year.

18

 
(10)  Calpine holds a 50% partnership interest in Whitby Cogeneration through its subsidiaries; however, it is operated by Atlantic 

Packaging Products Ltd.

(11)  Los Esteros Critical Energy Facility is currently under construction to upgrade from a 188 MW simple-cycle generation 

power plant to a 309 MW combined-cycle generation power plant.

We provide operations and maintenance services for all but three of the power plants in which we have an interest. Such 
services include the operation of power plants, geothermal steam fields, wells and well pumps and natural gas pipelines. We also 
supervise maintenance, materials purchasing and inventory control, manage cash flow, train staff and prepare operations and 
maintenance manuals for each power plant that we operate. As a power plant develops an operating history, we analyze its operation 
and may modify or upgrade equipment, or adjust operating procedures or maintenance measures to enhance the power plant’s 
reliability or profitability. Although we do not operate the Freeport Energy Center, our outage services subsidiary performs all 
major maintenance services for this plant under a contract with The Dow Chemical Company through April 2032.

Certain power plants in which we have an interest have been financed primarily with project financing that is structured 
to be serviced out of the cash flows derived from the sale of power (and, if applicable, thermal energy and capacity) produced by 
such power plants and generally provide that the obligations to pay interest and principal on the loans are secured solely by the 
capital stock or partnership interests, physical assets, contracts and/or cash flows attributable to the entities that own the power 
plants. The lenders under these project financings generally have no recourse for repayment against us or any of our assets or the 
assets of any other entity other than foreclosure on pledges of stock or partnership interests and the assets attributable to the entities 
that own the power plants. However, defaults under some project financings may result in cross-defaults to certain of our other 
debt and debt instruments, including our First Lien Notes, First Lien Term Loans, and Corporate Revolving Facility. Acceleration 
of the maturity of a project financing following a default may also result in a cross-acceleration of such other debt.

Substantially all of the power plants in which we have an interest are located on sites which we own or lease on a long-

term basis.

EMISSIONS AND OUR ENVIRONMENTAL PROFILE

Our environmental record has been widely recognized. We were an EPA Climate Leaders Partner with a stated goal to 
reduce GHG emissions, and we became the first power producer to earn the distinction of Climate Action LeaderTM. We have 
certified our GHG emissions inventory with the California Climate Action Registry every year since 2003. In 2011, our emissions 
of GHG amounted to about 41 million tons.

Natural Gas-Fired Generation

Our natural gas-fired, primarily combined-cycle fleet consumes significantly less fuel to generate power than conventional 
boiler/steam turbine power plants and emits fewer air pollutants per MWh of power produced as compared to coal-fired or oil-
fired power plants. All of our power plants have air emissions controls and most have selective catalytic reduction to further reduce 
emissions of nitrogen oxides, a precursor of atmospheric ozone. In addition, we have implemented a program of proprietary 
operating procedures to reduce natural gas consumption and further lower air pollutant emissions per MWh of power generated. 
The table below summarizes approximate air pollutant emission rates from our natural gas-fired, combined-cycle power plants 
compared to the average emission rates from U.S. coal-, oil- and natural gas-fired power plants as a group, based on the most 
recent statistics available to us.

The average U.S. coal-, oil- and natural gas-fired power plants’ emission rates were obtained from the U.S. Department of 
Energy’s Electric Power Annual Report for 2011. Emission rates are based on 2011 emissions and net generation. The U.S. 
Department of Energy has not yet released 2012 information.

The U.S. coal-, oil- and natural gas-fired power plant air emissions of mercury compounds were obtained from the EPA 
Toxics Release Inventory for 2011. Emission rates are based on 2011 emissions and net generation from U.S. Department 
of Energy’s Electric Power Annual Report for 2011.

Geothermal Generation

Our 725 MW fleet of geothermal turbine-based power plants utilizes a natural, renewable energy source, steam from the 
Earth’s interior, to generate power. Since these power plants do not burn fossil fuel, they are able to produce power with negligible 
CO2 (the principal GHG), NOX and SO2 emissions. Compared to the average U.S. coal-, oil- and natural gas-fired power plant, 
our Geysers Assets emit 99.9% less NOX, 100% less SO2 and 96.9% less CO2. There are 18 active geothermal power plants located 
in The Geysers region of northern California. We own and operate 15 of them. We recognize the importance of our Geysers Assets 
and we are committed to extending and expanding this renewable geothermal resource through the addition of new steam wells 
and wastewater recharge projects where clean, reclaimed water from local municipalities is recycled into the geothermal resource 
where it is converted by the Earth’s heat into steam for power production.

Water Conservation and Reclamation

We have also invested substantially in technologies and systems that reduce the impact of our operations on water as a 

natural resource:

•  We receive and inject an average of approximately 16 million gallons of reclaimed water per day into the geothermal 
steam reservoir at The Geysers where the water is naturally heated by the Earth, creating additional steam to fuel our 
Geysers Assets. Approximately 12 million gallons per day are received from the Santa Rosa Geysers Recharge Project, 
which we developed jointly with the City of Santa Rosa, and we receive, on average, approximately 4 million gallons a 
day from The Lake County Recharge Project from Lake County. 

• 

• 

In our combined-cycle power plants, we use mechanical draft cooling towers, which use up to 90% less water than 
conventional once-through cooling systems. Two of our combined-cycle power plants employ air-cooled condensers, 
which consume virtually no water for cooling.

In eleven of our operating power plants and one power plant under construction equipped with cooling towers, we reuse 
treated water from municipal treatment systems for cooling. By reusing water in these cooling towers, we avoid the usage 
of as much as 35 million gallons per day of valuable surface and/or groundwater for cooling.

•  Our Russell City Energy Center will use 100% reclaimed water from the City of Hayward’s Water Pollution Control 
Facility for cooling and boiler makeup, which will prevent nearly four million gallons of wastewater per day from being 
discharged into the San Francisco Bay.

GOVERNMENTAL AND REGULATORY MATTERS

We are subject to complex and stringent energy, environmental and other laws and regulations at the federal, state and 
local levels as well as within the RTO and ISO markets in which we participate in connection with the development, ownership 
and operation of our power plants. Federal and state legislative and regulatory actions continue to change how our business is 
regulated.

Environmental Matters

Federal Regulation of Air Emissions

The CAA provides for the regulation of air quality and air emissions, largely through state implementation of federal 
requirements. We believe that all of our operating power plants comply with existing federal and state performance standards 
mandated under the CAA. We continue to monitor and actively participate in EPA initiatives where we anticipate an impact on 
our business. Some of the more significant governmental and regulatory matters that affect our business are discussed below.

20

Criteria Pollutants and Hazardous Air Pollutants

The CAA requires the EPA to regulate emissions of pollutants considered harmful to public health and the environment. 
The EPA has set NAAQS for six “criteria” pollutants: carbon monoxide, lead, NO2, particulate matter (“PM”), ozone and SO2. 
In addition, the CAA regulates a large number of air pollutants that are known to cause or may reasonably be anticipated to cause 
adverse effects to human health or adverse environmental effects, known as hazardous air pollutants (“HAPs”). The EPA is required 
to issue technology-based national emissions standards for hazardous air pollutants (“NESHAPs”) to limit the release of specified 
HAPs from specific industrial sectors.

Mercury and Air Toxics Standards

On December 21, 2011, the EPA issued the National Emission Standards for Hazardous Air Pollutants from Coal- and 
Oil-fired Electric Utility Steam Generating Units and Standards of Performance for Fossil-Fuel-Fired Electric Utility, Industrial-
Commercial-Institutional,  and  Small  Industrial-Commercial-Institutional  Steam  Generating  Units,  otherwise  known  as  the 
Mercury and Air Toxics Standards (“MATS”). MATS will reduce emissions of all hazardous air pollutants emitted by coal- and 
oil-fired electric generating units, including mercury (Hg), arsenic (As), chromium (Cr), nickel (Ni) and acid gases.

The EPA estimates that there are approximately 1,400 units affected by MATS, consisting of approximately 1,100 existing 
coal-fired units and 300 oil-fired units at approximately 600 power plants. The CAA provides existing units three years from the 
effective date of MATS to achieve compliance. As a result, existing coal-fired units without emissions controls will need to retire 
or install controls on acid gases, mercury and particulate matter emissions by April 16, 2015. State enforcement authorities also 
have  discretion  under  the  CAA  to  provide  an  additional  year  for  technology  installation.  Further,  the  EPA  issued  a  policy 
memorandum which indicates that the EPA may provide, in limited circumstances due to delays in the installation of controls, an 
additional year extension for MATS compliance where necessary to maintain electric system reliability. Accordingly, although 
the EPA’s analysis indicates that it should take no longer than three years for most existing units to comply, they may have up to 
five years, or until April 16, 2017, to install controls and comply with MATS.

We are not directly affected by MATS because it does not apply to natural gas-fired units, peaking units or units that use 
fuel oil as a backup fuel. We believe that the emission standards are sufficiently stringent to force existing coal-fired units without 
emissions controls to retire or to install the necessary controls by April 16, 2015 (unless an extension is granted), which could 
benefit our competitive position.

Prior to the April 16, 2012 filing deadline, a total of 30 petitions for review challenging MATS were filed in the U.S. 
Court of Appeals for the D.C. Circuit (“D.C. Circuit”) and subsequently consolidated under the case White Stallion Energy Center 
v. EPA. On March 19, 2012, Calpine, along with other energy companies, filed a motion for leave to intervene in the consolidated 
case in support of the EPA. Petitioners are expected to argue that the rule is arbitrary and capricious because the EPA failed to 
adequately demonstrate its threshold finding that the rule is “appropriate and necessary”; the EPA failed to address their concerns 
that MATS could damage electricity grid reliability; and the standards for new sources are not achievable.

Several petitioners moved to sever the issues specific to the standards for new coal-fired power plants and expedite 
briefing on those issues. On June 28, 2012, the D.C. Circuit granted the motion to sever and expedite briefing, and the new unit 
case is being considered under a separate docket number. However, on July 20, 2012, the EPA granted partial administrative 
reconsideration of certain issues affecting new units, namely, measurement issues related to mercury and the data underlying 
particulate matter and hydrogen chloride emissions standards. The EPA stayed the effectiveness of MATS with respect to the new 
unit issues under reconsideration.

As a consequence, on September 12, 2012, the D.C. Circuit stayed the severed case addressing standards for new units 
and held that case in abeyance pending the EPA’s administrative reconsideration of the new unit standards. In response to the 
petition for reconsideration, the EPA issued a proposed rule reconsidering MATS for new sources on November 30, 2012. The 
proposed rule would, among other things, amend certain new source standards and the requirements applicable during periods of 
startup and shut down. The public comment period on the proposed rule for new units closed on January 7, 2013. The EPA will 
issue a final reconsideration in March 2013. 

The D.C. Circuit is being briefed on the remaining challenges to MATS that are not being held in abeyance (e.g., challenges 

to existing unit standards). Oral argument has not been scheduled for the remaining consolidated challenges to MATS.

Cross-State Air Pollution Rule

On July 6, 2011, the EPA finalized the Cross-State Air Pollution Rule (“CSAPR”) which would require a total of 28 
states, primarily in the eastern U.S., to reduce annual SO2 emissions, annual NOx emissions and/or ozone season NOx emissions 

21

to assist in attaining three NAAQS: the 1997 annual PM2.5 NAAQS, the 1997 8-hour ozone NAAQS, and the 2006 24-hour 
PM2.5 NAAQS.

CSAPR established an unlimited intrastate and limited interstate trading program with allowances allocated to sources 
based on historic heat input but capped at maximum annual emissions from 2003 to 2010. At current capacity factors, Calpine 
would have been allocated sufficient allowances; thus, CSAPR was not expected to have a negative impact on our operations. We 
expected the overall impact of CSAPR to be positive for Calpine because the significant emissions reduction requirements would 
require coal-fired electric generating units to either purchase allowances, switch to more expensive fuels, install air pollution 
controls, or reduce or discontinue operations, thereby incenting the increased utilization of existing, and development of new, 
natural gas-fired power plants.

A number of power generation companies, states and other groups filed petitions for review in the D.C. Circuit challenging 
CSAPR, and these cases were consolidated under EME Homer City Generation v. EPA. Calpine, other power generation companies, 
states, cities, and public health groups were granted intervenor status on behalf of respondent EPA.

On August 21, 2012, the D.C. Circuit vacated CSAPR. The D.C. Circuit ordered the EPA to continue administering CAIR, 
which the EPA has been implementing since the D.C. Circuit stayed CSAPR in December 2011 and which CSAPR was designed 
to replace due to the flaws in CAIR identified by the D.C. Circuit in North Carolina v. EPA.

The EPA petitioned for en banc rehearing (i.e., by all active judges on the D.C. Circuit) on October 5, 2012. Intervenors 
supporting the EPA also submitted three petitions for en banc rehearing upon similar grounds, including one submitted by a 
coalition of environmental and public health organizations, one by a group of cities and states (including the states of North 
Carolina, Connecticut, Delaware, Illinois, Maryland, Massachusetts, New York, Rhode Island and Vermont) and one jointly filed 
by Calpine and Exelon Corporation. On January 24, 2013, the D.C. Circuit denied en banc rehearing in this case. A petition for a 
writ of certiorari to appeal this decision to the Supreme Court may still be filed by the EPA or any other party. Assuming the 
decision is not reversed by the U.S. Supreme Court upon a petition for writ of certiorari, the EPA must continue to implement 
CAIR while it creates a replacement for CSAPR.

CAIR and Multi-Pollutant Program

Pursuant to authority granted under the CAA, the EPA promulgated the Clean Air Interstate Rule, or CAIR, regulations 
in March 2005, applicable to 28 eastern states and the District of Columbia, to facilitate attainment of its ozone and fine particulates 
NAAQS issued in 1997. CAIR’s goal is to reduce SO2 emissions in these states by over 70%, and NOX emissions by over 60% 
from 2003 levels by 2015. CAIR established annual Cap-and-trade programs for SO2 and NOX as well as a seasonal program for 
NOX. On July 11, 2008, the D.C. Circuit invalidated CAIR, stating that the “EPA’s approach – region-wide caps with no state 
specific quantitative contribution determinations or emission requirements – is fundamentally flawed.” The court did not overturn 
the existing Cap-and-trade program for SO2 reductions under the Acid Rain Program or the existing ozone season Cap-and-trade 
program under the NOX State Implementation Plan Call. On September 25, 2008, the EPA petitioned the court for rehearing. On 
December 23, 2008, the court remanded CAIR without vacatur for the EPA to conduct further proceedings consistent with the 
July 11, 2008 opinion. As a result of the court’s decision, CAIR was left intact and went into effect as planned on January 1, 2009, 
for many of our power plants located throughout the eastern and central U.S. Due to favorable allowance allocations, particularly 
in Texas, we have a net surplus of annual NOX allowances and the net financial impact of the program to our operations is positive. 
As a result of CSAPR being vacated in August 2012, the D.C. Circuit reinstated CAIR until the EPA creates a replacement for 
CSAPR.

GHG Emissions

On April 2, 2007, the U.S. Supreme Court in Massachusetts v. EPA ruled that the EPA has the authority to regulate GHG 
emissions under the CAA. In response to Massachusetts, the EPA issued an endangerment finding for GHGs on December 7, 
2009,  determining  that  concentrations  of  six  GHGs  endanger  the  public  health  and  welfare.  Further,  pursuant  to  the  CAA’s 
requirement that the EPA establish motor-vehicle emission standards for “any air pollutant . . . which may reasonably be anticipated 
to endanger public health or welfare,” the EPA promulgated the so-called “Tailpipe Rule” for GHGs, which set GHG emission 
standards for cars and light trucks.

Under the EPA’s longstanding interpretation of the CAA, the Tailpipe Rule automatically triggered regulation of stationary 
sources  of  GHG  emissions  under  the  Prevention  of  Significant  Deterioration  (“PSD”)  program  (which  requires  state-issued 
construction permits for stationary sources that have the potential to emit over 100 or 250 tons per year (“tpy”), the applicable 
threshold depending on the type of source, of “any air pollutant”) and Title V (which requires state-issued operating permits for 
stationary sources that have the potential to emit at least 100 tpy of “any air pollutant”). Accordingly, the EPA issued two rules 
phasing in stationary source GHG regulation. In the Timing Rule, the EPA delayed when major stationary sources of GHGs would 
otherwise be subject to PSD and Title V permitting, concluding that these requirements would commence on January 2, 2011, the 

22

date on which the Tailpipe Rule became effective. In the Tailoring Rule, the EPA departed from the CAA’s 100/250 tpy emissions 
thresholds and provided that only the largest sources, those exceeding 75,000 or 100,000 tpy carbon dioxide equivalent (“CO2e”), 
depending on the program and project, would initially be subject to GHG permitting.

Under Step 1 of the Tailoring Rule (beginning in January 2011), new or modified sources already required to obtain a 
PSD permit due to their emissions of conventional regulated pollutants must satisfy best available control technology (“BACT”) 
requirements for GHGs if they emit or have the potential to emit at least 75,000 tpy CO2e. Under Step 2 of the Tailoring Rule 
(beginning in July 2011), new sources that emit or have the potential to emit at least 100,000 tpy CO2e and existing sources that 
emit at that level and that undertake modifications that increase emissions by at least 75,000 tpy CO2e must obtain a PSD permit 
and satisfy BACT requirements for GHGs, regardless of their emissions of any conventional pollutants. Step 3 of the Tailoring 
Rule was finalized in July 2012 and maintained the GHG PSD and Title V permitting thresholds specified under Step 2.

The EPA has issued guidance to permitting authorities on the implementation of GHG BACT that focuses on energy 
efficiency. We believe that the impact of the Tailoring Rule will be neutral to us because we expect that our efficient power plants 
would be found to meet BACT for GHGs if required to undergo PSD review. Calpine’s Russell City Energy Center, a 619 MW 
combined-cycle power plant (Calpine’s 75% net interest is 464 MW) being constructed in Hayward, California, voluntarily accepted 
GHG BACT limits in its PSD permit before such limits were required by law.

More than sixty petitions for review of these EPA rules were filed by industry and states, which were subsequently 
consolidated in the D.C. Circuit case Coalition for Responsible Regulation v. EPA. On June 26, 2012, the D.C. Circuit, in an 
unsigned per curiam opinion, upheld all of the challenged GHG regulations. Specifically, the D.C. Circuit denied the petitions 
relating to the Endangerment Finding and the Tailpipe Rule on the merits, while dismissing the petitions for review of the Timing 
Rule and the Tailoring Rule on constitutional standing grounds.

On August  10,  2012,  industry  groups  requested  rehearing  en  banc  of  the  D.C.  Circuit’s  decision  in  Coalition  for 
Responsible Regulation. On October 12, 2012, the EPA filed its response in opposition to the rehearing petition. The D.C. Circuit 
denied en banc review on December 20, 2012. The petitioners can still petition for a writ of certiorari to the U.S. Supreme Court, 
which must be done by March 20, 2013.

In light of the rehearing petition, on October 9, 2012, the D.C. Circuit decided to hold in abeyance a related case regarding 
Step 3 of the EPA’s Tailoring Rule (American Petroleum Institute v. EPA). The parties were directed to file motions to govern 
future proceedings in American Petroleum Institute within 30 days of the D.C. Circuit’s decision regarding en banc review in 
Coalition for Responsible Regulation. The case is still being held in abeyance and no motion has been filed seeking to release the 
case from abeyance.

In a related development, the EPA published a proposed New Source Performance Standard (“NSPS”) for GHG emissions 
from new electric generating units on April 13, 2012. The proposed rule would establish an output-based CO2 emissions standard 
of 1,000 lbs/MWh gross for new fossil fuel-fired generating units, which include boilers, integrated gasification combined-cycle 
units and stationary combined-cycle turbine units greater than 25 MW. The emissions standard is based on the performance of 
natural gas combined-cycle technology. The proposed NSPS would not apply to simple-cycle plants, plants that burn biomass, 
existing sources, sources being modified, or so-called “transitional sources” (i.e., coal-fired plants that received PSD permits by 
the publication date of the proposed rule (April 13, 2012) and commence construction within 12 months of the publication date 
of the proposal).

The proposed NSPS would have no impact on Calpine’s fleet or development plans. According to the EPA, the proposed 
NSPS would result in no notable compliance costs because, even in its absence, the electric sector would choose to build natural 
gas-fired electric generating units that already comply with the proposed standard.

The comment period on the proposed NSPS rule closed on June 25, 2012. Although the proposal is not yet final, several 
developers of permitted coal-fired power plants that could not meet the proposed NSPS without installation of carbon capture and 
storage technology filed suit in the D.C. Circuit, challenging the EPA’s proposal. On December 13, 2012, the D.C. Circuit dismissed 
the industry challenge to the proposed NSPS because the proposed rule is not “final agency action” subject to judicial review.

The EPA expects to finalize the proposed NSPS in March 2013.

Fees on Permissible Emissions

Section 185 of the CAA requires major stationary sources of NOX and volatile organic compounds (“VOCs”), such as 
power plants and refineries, in areas that fail to attain the NAAQS for ozone by the attainment date to pay a fee to the state or, if 
the state fails to collect the fee, the EPA. The fee is set in the CAA at $5,000 per ton of NOX or VOC (adjusted for inflation or 
approximately $9,000 per ton in 2011) and is payable on emissions that exceed 80% of each individual power plant’s baseline 

23

emissions, which are established in the year before the attainment date; however, the EPA has provided guidance for the calculation 
of alternative baselines. The fee will remain in effect until the designated area achieves attainment.

We operate seven power plants in Texas and one in California that are located within a designated nonattainment area 
subject to Section 185. On January 5, 2010, the EPA issued guidance on developing fee programs required under Section 185, but 
that guidance was vacated by the D.C. Circuit in 2011 due to the EPA’s failure to follow notice-and-comment rulemaking procedures 
in its publication. On August 20, 2012, the EPA finalized approval of San Joaquin Valley Unified Air Pollution Control District’s 
(“SJVUAPCD”) fee-equivalent program, which the EPA determined is not less stringent than the program required by Section 
185, and, therefore, is approvable as an equivalent alternative program. Environmentalists have challenged EPA’s approval of this 
program in the U.S. Court of Appeals for the Ninth Circuit. The lawsuit is currently pending.

The TCEQ proposed a rule in November 2012 to create a Section 185 program, using an approach similar to that used 
in the approved SJVUAPCD program. We estimate that compliance with this fee could result in additional costs to us of up to $4 
million on an annual basis and our financial statements include accruals for our estimated Section 185 fees. In addition to this 
annual fee, we have accrued our estimate for Section 185 fees that may be applied retroactively, although it is unclear whether the 
EPA intends to require such retroactive fees to be collected. Our estimates are dependent upon a number of factors that could 
change in the future dependent upon, among other things: the EPA approval of state rulemakings, the designation of nonattainment 
status, the outcome of pending and potential litigation challenging the EPA’s approvals, the number of our operational power plants 
located in these areas and our emissions of NOX and VOC.

On June 18, 2012, the EPA determined that the New York-Northern New Jersey-Long Island (“NY-NJ-CT”) one-hour 
ozone attainment area failed to achieve the one-hour NAAQS by the applicable deadline, but also that it is currently attaining the 
one-hour standard. As a result of this action, our facilities in New York and New Jersey will not incur Section 185 fees as of the 
date of that determination. The EPA has not taken a firm position on retroactive collection of Section185 fees.

Acid Rain Program

As a result of the 1990 CAA amendments, the EPA established a Cap-and-trade program for SO2 emissions from power 
plants throughout the U.S. Starting with Phase II of the program in 2000, a permanent ceiling (or cap) was set at 10 million tons 
per year, declining to 8.95 million tons per year by 2010. The EPA allocated SO2 allowances to power plants. Each allowance 
permits a unit to emit one ton of SO2 during or after a specified year, and allowances may be bought, sold or banked. All but a 
small percentage of allowances were allocated to power plants placed into service before 1990. Our power plants currently receive 
sufficient free SO2 allowances; therefore, we will have no compliance expense for this program.

Regional and State Air Emissions Activities

Several states and regional organizations are developing, or already have developed, state-specific or regional initiatives 
to reduce GHG emissions through mandatory programs. The most advanced programs include the RGGI in the northeast states 
and California’s suite of GHG policies promulgated pursuant to AB 32, including its Cap-and-trade program. The evolution of 
these programs could have a material impact on our business.

California: GHG — Cap-and-Trade Regulation

California’s AB 32 requires the state to return to 1990 GHG emissions levels by 2020. To meet these levels, CARB has 
promulgated a number of regulations, including the Cap-and-trade regulation. In late 2011, CARB finalized its Cap-and-trade 
regulation and mandatory reporting regulation, which took effect on January 1, 2012. These regulations were further amended by 
CARB in 2012.

Under the Cap-and-trade regulation, the first compliance period for covered entities like Calpine began on January 1, 
2013 and runs through the end of 2014. The second and third compliance periods cover 2015 through 2017 and 2018 through 
2020,  respectively.  Covered  entities  must  hold  compliance  instruments,  which  include  allowances  and  offsets,  in  an  amount 
equivalent to their emissions from sources of GHG located in California and from power imported into California. The first auction 
of GHG allowances was held on November 14, 2012 and included the sale of 2013 and 2015 vintage allowances. Quarterly auctions 
will be held every year from 2013 to 2020 with the next auction scheduled for February 19, 2013. The emissions market is currently 
functioning and the cost of the emissions permits is reflected in market pricing.

Currently,  there  are  two  pending  lawsuits  challenging  the  Cap-and-trade  regulation.  On  March  28,  2012,  two 
environmental organizations filed a lawsuit in San Francisco Superior Court seeking to invalidate the four protocols published by 
CARB for issuing offsets. On January 25, 2013, the court rejected the petitioners’ claims, holding that CARB’s development of 
the protocols was consistent with AB 32. The petitioners have until May 26, 2013 to appeal the decision in the California Court 
of Appeals. Additionally, on November 13, 2012, the California Chamber of Commerce filed a complaint in the Sacramento 

24

Superior Court challenging CARB’s authority to auction allowances. The Sacramento Superior Court is scheduled to hold a hearing 
on the merits in that case on May 31, 2013. We cannot predict the ultimate success of either of these lawsuits nor can we predict 
whether there will be any additional legal challenges filed against the regulation or what the associated impacts of any such 
litigation would be.

In  September  2012,  the  CARB  Board  directed  its  staff,  by  mid-2013,  to  propose  amendments  to  the  Cap-and-trade 
regulation that would, among other things, increase the auction purchase limit for covered entities and provide allowances to 
covered entities that have long-term contracts that do not allow the costs of compliance to be passed through to their customers. 
On January 8, 2013, CARB published a notice for a 15-day rulemaking concerning linkage of California’s and Quebec’s Cap-
and-trade programs (“Linkage Notice”). The Linkage Notice provides background for CARB’s expected request that the California 
Governor  make  certain  findings  under  Senate  Bill  (“SB”)  1018,  which  are  required  before  California  links  with  any  other 
jurisdiction’s  Cap-and-trade  program.  If  the  Governor  makes  these  findings  and  CARB  approves  the  proposed  amendments, 
California and Quebec could hold their first joint auction of GHG allowances in August 2013. CARB’s economic analysis estimates 
that linkage between California and Quebec has the potential to increase California’s GHG allowance prices by 5% to 15%.

Overall, we support AB 32 and expect the net impact of the Cap-and-trade regulation to be beneficial to Calpine. We also 

believe we are positioned to comply with these regulations.

Northeast and Mid-Atlantic States: CO2 – RGGI

On January 1, 2009, ten northeast and Mid-Atlantic states implemented a Cap-and-trade program, RGGI, which affects 
our power plants in Maine, New York and Delaware (together emitting about 3.9 million tons of CO2 annually). In 2011, New 
Jersey announced its withdrawal from the RGGI program effective as of the 2012 compliance year.

RGGI caps regional CO2 emissions and requires generators to acquire one allowance for every ton of CO2 emitted over 
a  three-year  compliance  period. Apart  from  state-specific  set-asides  and  other  factors,  the  vast  majority  of  the  region’s  CO2 
allowances are distributed to the market via quarterly public auctions. The most recent RGGI auction, conducted on December 5, 
2012, cleared at the program’s floor price of $1.93 per allowance.

We are required to purchase allowances by buying them in RGGI public auctions or via the secondary market, or by 
investment in qualified offsets, to cover CO2 emissions from our power plants in the RGGI region. We have also received annual 
allocations from New York’s long-term contract set-aside pool to cover some of the CO2 emissions attributable to our PPAs at 
both the Kennedy International Airport Power Plant and Stony Brook Power Plant. We do not anticipate any significant business 
or financial impact from RGGI, given the efficiency of our power plants in RGGI states.

The original memorandum of understanding under which the states created RGGI envisioned a review of the program 
after the first compliance period, which ended in 2011. The intent of the review is to assess the need for modifications to the RGGI 
program design. The program review has incorporated input from the states, regulated industry, and other stakeholders, including 
environmental advocacy groups. Calpine is actively participating in the process. As a result of the program review, a model rule 
was issued on February 7, 2013, with a significantly lower regional emission cap. To enact this change, RGGI states must promulgate 
the model rule or something substantially similar at the state level. The RGGI states have indicated a desire to incorporate the 
model rule into state regulations by the end of 2013, with a new emission cap taking effect in 2014. We do not expect any material 
impact to our business from this change in regulations.

Texas: NOX

Pursuant to authority granted under the CAA, regulations adopted by the TCEQ to attain the one-hour and eight-hour 
NAAQS for ozone included the establishment of a Cap-and-trade program for NOX emitted by power plants in the Houston-
Galveston-Brazoria ozone nonattainment area. We own and operate seven power plants that participate in this program, all of 
which received free NOX allowances based on historical operating profiles. At this time, our Houston-area power plants have 
sufficient NOX allowances to meet forecasted obligations under the program.

New Jersey: NOX

New Jersey’s High Electric Demand Day (“HEDD”) Rule limits NOx emissions from turbines and boilers. Beginning in 
2015, Phase 2 of the HEDD Rule will require investments in emissions controls on some of our peaking power plants. We have 
provided notice to PJM that our 158 MW Deepwater Energy Center, 68 MW Cedar Energy Center and 60 MW Missouri Avenue 
Energy Center will be physically unable to perform in the delivery year 2015 as a result of the HEDD Rule and that we plan to 
retire the units before the commencement of the PJM Reliability Pricing Model 2015/2016 delivery year. We received PJM’s 
response in May 2012 in which PJM indicated its agreement with our deactivation request provided certain planned transmission 

25

upgrades are completed as scheduled. In the event the transmission upgrades are not completed as planned, PJM may require one 
or more of the plants to continue to operate for a period of time, but we would be entitled to full cost recovery.

We plan to install emissions controls equipment at our 73 MW Carll’s Corner Energy Center and 67 MW Mickleton 
Energy Center as these power plants cleared PJM’s 2015/2016 base residual auction. Our 77 MW Middle Energy Center did not 
clear  PJM’s  2015/2016  base  residual  auction and  we  have  provided  notice  to  PJM  of  our  intent  to  retire  this  unit  before  the 
commencement of the PJM Reliability Pricing Model 2015/2016 delivery year. All six of our power plants impacted by the HEDD 
Rule will be fully depreciated by June 2015. We expect that the retirement of these power plants or installation of emissions 
controls will not have a material impact on our financial condition, results of operations or cash flows.

Renewable Portfolio Standards

Policymakers have been considering variations of an RPS at the federal and state level. Generally, an RPS requires each 
retail seller of electricity to include in its resource portfolio (the resources procured by the retail seller to supply its retail customers) 
a certain amount of power generated from renewable or clean energy resources by a certain date.

Federal RPS

Although there is currently no national RPS, President Obama has stated his goal is to have 80% of the nation’s electricity 
provided from clean energy resources, which includes natural gas resources, by 2035, and some U.S. Congressional members 
have expressed interest in national renewable or clean energy standard legislation. It is too early to determine whether or not the 
enactment of a national RPS will have a positive or negative impact on us. Depending on the RPS structure, an RPS could enhance 
the value of our existing Geysers Assets. However, an RPS would likely initially drive up the number of wind and solar resources, 
which could negatively impact the dispatch of our natural gas-fired power plants, primarily in Texas and California. Conversely, 
our natural gas power plants could benefit by providing complementary/back-up service for these intermittent renewable resources 
or by being included in a clean energy standard.

California RPS

On April 12, 2011, California’s Governor signed into law legislation establishing a new and higher RPS. The new law 
requires implementation of a 33% RPS by 2020, with intermediate targets between 2010 and 2020. The previous RPS legislation 
required certain retail power providers to generate or procure 20% of the power they sell to retail customers from renewable 
resources beginning in 2010. The new standard applies to all load-serving entities, including entities such as large municipal 
utilities that are not subject to CPUC jurisdiction. Under the new law, there are limits on different “buckets” of procurement that 
can be used to satisfy the RPS. Load-serving entities must satisfy at least a fraction of their compliance obligations with renewable 
power from resources located in California or delivered into California within the hour. Similarly, the legislation places limits on 
the use of “firmed and shaped” transactions and unbundled RECs – claims to the renewable aspect of the power produced by a 
renewable resource that can be traded separately from the underlying power. In general, the ability to use “firmed and shaped” 
transactions and unbundled RECs becomes more limited over the course of the implementation period. On December 1, 2011, the 
CPUC issued a decision on intermediate RPS procurement targets between the present and 2020. On December 15, 2011, the 
CPUC issued a decision clarifying exactly what transactions will fall into which bucket. In our role as an energy service provider, 
we are subject to the RPS requirements and continue to meet our compliance obligations. The increase in solar and wind generation 
on the state’s electrical grid has increased the need for flexible thermal generation which may be beneficial to Calpine.

Other

A number of additional states have an RPS in place. Existing state-specific RPS requirements may change due to regulatory 

and/or legislative initiatives, and other states may consider implementing enforceable RPS in the future.

Other Environmental Regulations

In addition to controls on air emissions, our power plants and the equipment necessary to support them are subject to 
other extensive federal, state and local laws and regulations adopted for the protection of the environment and to regulate land 
use. The laws and regulations applicable to us primarily involve the discharge of emissions into the water and the use of water, 
but can also include wetlands protection and preservation, endangered species, hazardous materials handling and disposal, waste 
disposal and noise regulations. Noncompliance with environmental laws and regulations can result in the imposition of civil or 
criminal fines or penalties. In some instances, environmental laws may also impose clean-up or other remedial obligations in the 
event of a release of pollutants or contaminants into the environment. The following federal laws are among the more significant 
environmental laws that apply to us. In most cases, analogous state laws also exist that may impose similar and, in some cases, 
more  stringent  requirements  on  us  than  those  discussed  below.  In  general,  our  relatively  clean  portfolio  as  compared  to  our 
competitors affords us some advantage in complying with these laws.

26

Clean Water Act and Water Intake Rule

The federal Clean Water Act establishes requirements relating to the discharge of pollutants into waters of the U.S. We 
are required to obtain wastewater and storm water discharge permits for wastewater and runoff, respectively, for some of our 
power plants. In addition, we are required to maintain a spill prevention control and countermeasure plan with respect to some of 
our natural gas-fired power plants. We believe that we are in material compliance with applicable discharge requirements of the 
Clean Water Act.

Section 316(b) of the Clean Water Act requires that the location, design, construction and capacity of cooling water intake 
structures reflect the best technology available for minimizing adverse environmental impact. The EPA finalized the Phase I Rule 
in 2001, which applies to new facilities. The EPA initially promulgated the Phase II Rule, applying to large existing facilities, in 
2004. However, the Phase II Rule was subsequently suspended and the EPA is required to finalize an updated rule applying to 
existing facilities by June 27, 2013. Calpine continues to participate in the rulemaking process; however, while the Section 316
(b) rule will likely affect our competitors, we do not expect these rules to have a material impact on our operations because only 
two peaking power plants we own employ once-through cooling systems, one of which (Deepwater Energy Center) is scheduled 
to retire in 2015.

Additionally, the EPA is bound by a consent decree to issue a final rule to establish revised effluent limitation guidelines 
for the steam electric point source category by January 31, 2014. This rule is unlikely to have a material impact on our operations.

In California, the EPA delegates the implementation of Section 316(b) to the California State Water Resources Control 
Board (“SWRCB”). SWRCB has promulgated its own once-through cooling policy that establishes a schedule for once-through 
cooling units to install cooling towers or reduce entrainment and impingement to comparable levels as would be achieved with a 
cooling tower, or be retired. The compliance dates for approximately 12,000 MW of once-through cooling capacity in California 
occur between 2012 and 2020. We do not anticipate that the SWRCB’s policy will have a negative impact on our operations, as 
none of our power plants in California utilize once-through cooling systems.

Safe Drinking Water Act

Part C of the Safe Drinking Water Act establishes the underground injection control program that regulates the disposal 
of wastes by means of deep well injection. Although geothermal production wells, which are wells that bring steam to the surface, 
are exempt under the Energy Policy Act of 2005 (“EPAct 2005”), we use geothermal re-injection wells to inject reclaimed wastewater 
back into the steam reservoir, which are subject to the underground injection control program. We believe that we are in material 
compliance with Part C of the Safe Drinking Water Act.

Resource Conservation and Recovery Act

The Resource Conservation and Recovery Act (“RCRA”), regulates the management of solid and hazardous waste. With 
respect  to  our  solid  waste  disposal  practices  at  our  power  plants  and  steam  fields  located  in The  Geysers  region  of  northern 
California, we are also subject to certain solid waste requirements under applicable California laws. We believe that our operations 
are in material compliance with RCRA and related state laws.

On June 21, 2010, the EPA proposed a rule to regulate coal combustion residuals (“CCRs”) under RCRA. A Notice of 
Data Availability (“NODA”) was issued on October 12, 2011; but, there has not been any public movement on the rule since then. 
The EPA seeks to establish more stringent dam safety requirements to enhance performance surface impoundments used to manage 
CCRs. The EPA also seeks to regulate disposal of CCRs and has proposed to either regulate them as hazardous waste under Subtitle 
C of RCRA, or as nonhazardous waste under Subtitle D of RCRA. Both options will impose additional waste management costs 
on our competitors who rely on coal as a fuel. The EPA estimates a net present value cost of $3 billion to $21 billion to coal plants. 
We do not use coal so the CCRs rule, when finalized, will have no direct impact on our financial condition, results of operations 
or cash flows.

Comprehensive Environmental Response, Compensation and Liability Act

The Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), also referred to as the 
Superfund,  requires  cleanup  of  sites  from  which  there  has  been  a  release  or  threatened  release  of  hazardous  substances,  and 
authorizes the EPA to take any necessary response action at Superfund sites, including ordering potentially responsible parties 
liable for the release to pay for such actions. Potentially responsible parties are broadly defined under CERCLA to include past 
and present owners and operators of, as well as generators of, wastes sent to a site. As of the filing of this Report, we are not subject 
to any material liability for any Superfund matters. However, we generate certain wastes, including hazardous wastes, and send 
certain of our wastes to third party waste disposal sites. As a result, there can be no assurance that we will not incur a liability 
under CERCLA in the future.

27

Federal Litigation regarding Liability for GHG Emissions

Litigation relating to common law tort liability for GHG emissions is working its way through the federal courts. While 
the U.S. Supreme Court has established that, in light of the EPA regulation of GHGs under the CAA, companies cannot be sued 
under federal common law theories of nuisance and negligence for their contribution to climate change, questions remain as to 
the viability of related state-law claims.

On September 21, 2009, the U.S. Court of Appeals for the Second Circuit (“Second Circuit”) issued a ruling in State of 
Connecticut v. American Electric Power Company Inc., reversing a lower court’s dismissal of two public nuisance claims filed 
by various states, municipalities and private entities against operators of coal-fired power plants. Plaintiffs argued that the power 
plant defendants contribute to global warming by emitting 650 million tons of CO2 per year and these emissions are causing and 
will continue to cause serious harm affecting human health and natural resources. The lower court held that plaintiffs’ claims 
presented a non-legal political question and dismissed the complaints. The Second Circuit vacated the lower court’s decision, 
ruling in favor of the plaintiffs. 

The Second Circuit’s decision was appealed to the U.S. Supreme Court. On June 20, 2011, the Supreme Court issued a 
decision rejecting the plaintiffs’ federal common law claim. The Court found that even if a federal common law claim could be 
made  by  plaintiffs,  the  CAA  essentially  “displaced”  that  claim.  The  case  was  remanded  to  the  Second  Circuit  for  further 
consideration of whether the plaintiffs may raise their claims under state common law or whether those claims are also preempted 
by federal law. The Second Circuit remanded to the district court for additional fact-finding. On December 6, 2011, the case was 
voluntarily dismissed. We cannot predict what impact the precedent of this case could have on our business.

The Supreme Court’s decision in the above matter has had significant consequences for other climate change cases, 
including Native Village of Kivalina v. ExxonMobil. In Kivalina, a federal district court in California sided with the defendants 
(multiple oil, energy and utility companies) against the Village of Kivalina, a small, self-governing tribe of Inupiat people who 
reside north of the Arctic Circle. The residents of Kivalina had sued the defendants for damages under federal nuisance law arguing 
that, as a result of global warming to which the defendants allegedly contributed, Kivalina is subject to coastal storm waves and 
surges. On September 30, 2009, the court ruled in favor of the defendants, finding that the political question doctrine precluded 
the court from considering the plaintiff’s federal public nuisance claim. On September 21, 2012, the U.S. Court of Appeals for 
the Ninth Circuit affirmed, holding that the intervening U.S. Supreme Court case in American Electric Power militated against 
judicial review of Kivalina’s claim because the CAA displaces federal common law addressing domestic GHG emissions. We 
cannot predict what impact the precedent of this case could have on our business.

Power and Natural Gas Matters

Federal Regulation of Power

FERC Jurisdiction

Electric utilities have been highly regulated by the federal government since the 1930s, principally under the Federal 
Power Act (“FPA”), and the U.S. Public Utility Holding Company Act of 1935. These statutes have been amended and supplemented 
by subsequent legislation, including PURPA, EPAct 2005, and PUHCA 2005. These particular statutes and regulations are discussed 
in more detail below.

The FPA grants the federal government broad authority over electric utilities and independent power producers, and vests 
its  authority  in  FERC.  Unless  otherwise  exempt,  any  person  that  owns  or  operates  facilities  used  for  the  wholesale  sale  or 
transmission of power in interstate commerce is a public utility subject to FERC’s jurisdiction. FERC governs, among other things, 
the disposition of certain utility property, the issuance of securities by public utilities, the rates, the terms and conditions for the 
transmission or wholesale sale of power in interstate commerce, the interlocking directorates, and the uniform system of accounts 
and reporting requirements for public utilities.

The majority of our power plants are subject to FERC’s jurisdiction; however, certain power plants qualify for available 
exemptions. FERC’s jurisdiction over EWGs under the FPA applies to the majority of our power plants because they are EWGs 
or are owned by EWGs, except our EWGs located in ERCOT. Power plants located in ERCOT are exempt from many FERC 
regulations under the FPA. Many of our power plants that are not EWGs are operated as QFs under PURPA. Several of our affiliates 
have been granted authority to engage in sales at market-based rates and blanket authority to issue securities, and have also been 
granted certain waivers of FERC reporting and accounting regulations available to non-traditional public utilities; however, we 
cannot assure that such authorities or waivers will not be revoked for these affiliates or will be granted in the future to other 
affiliates.

28

FERC has the right to review books and records of “holding companies,” as defined in PUHCA 2005, that are determined 
by FERC to be relevant to the companies’ respective FERC-jurisdictional rates. We are considered a holding company, as defined 
in PUHCA 2005, by virtue of our control of the outstanding voting securities of our subsidiaries that own or operate power plants 
used for the generation of power for sale, or that are themselves holding companies. However, we are exempt from FERC’s books 
and records inspection rights pursuant to one of the limited exemptions under PUHCA 2005 as we are a holding company due 
solely to our owning one or more QFs, EWGs and Foreign Utility Companies (“FUCOs”). If any of our entities were not a QF, 
EWG or FUCO, then we and our holding company subsidiaries would be subject to the books and records access requirement.

FERC’s policies and rules will continue to evolve, and FERC may amend or revise them, or may introduce new policies 

or rules in the future. The impact of such policies and rules on our business is uncertain and cannot be predicted at this time.

FERC Regulation of Market-Based Rates

Under the FPA and FERC’s regulations, the wholesale sale of power at market-based or cost-based rates requires that 
the seller have authorization issued by FERC to sell power at wholesale pursuant to a FERC-accepted rate schedule. FERC grants 
market-based rate authorization based on several criteria, including a showing that the seller and its affiliates lack market power 
in generation and transmission, that the seller and its affiliates cannot erect other barriers to market entry and that there is no 
opportunity for abusive transactions involving regulated affiliates of the seller. All of our affiliates that own domestic power plants, 
except for certain of those power plants that are QFs under PURPA or that are located in ERCOT, as well as our market-based 
rate companies, are currently authorized by FERC to make wholesale sales of power at market-based rates.

Market-based rate authorization could possibly be revoked for any of our market-based rate companies if they fail to 
continue to satisfy FERC’s current or future criteria, or if FERC eliminates or restricts the ability of wholesale sellers of power to 
make sales at market-based rates. If market-based rate authority was revoked or restricted, affected power plants could be required 
to make wholesale sales of power based on cost-of-service rates, which could negatively impact their revenues.

FERC’s regulations specifically prohibit the manipulation of the power markets by making it unlawful for any entity in 
connection with the purchase or sale of power, or the purchase or sale of power transmission service under FERC’s jurisdiction, 
to engage in fraudulent or deceptive practices.

To ward against market manipulation, FERC requires us and other sellers making sales pursuant to their market-based 
rate authority to file certain reports, including quarterly reports of contract and transaction data, notices of any change in status 
and triennial updated market power analyses. If a seller does not timely file these reports or notices, FERC can revoke the seller’s 
market-based rate authority. FERC’s regulations also contain four market behavior rules that apply to sellers with market-based 
rate authority. These rules address such matters as compliance with organized RTO or ISO market rules, communication of accurate 
information, price reporting to publishers of power or natural gas price indices, and record retention. Failure to comply with these 
regulations can lead to sanctions by FERC, including penalties and suspension or revocation of market-based rate authority.

FERC Regulation of Transfers of Jurisdictional Facilities

Dispositions of our jurisdictional facilities or certain types of financing arrangements may require prior FERC approval, 
which could result in revised terms or impose additional costs, or cause a transaction to be delayed or terminated. Pursuant to 
Section 203 of the FPA, as amended by EPAct 2005, a public utility must obtain authorization from FERC before the public utility 
is permitted to: sell, lease or dispose of FERC-jurisdictional facilities with a value in excess of $10 million; merge or consolidate 
facilities with those of another entity; or acquire any security or securities with a value in excess of $10 million issued by another 
public utility. FERC’s prior approval is also required for transactions involving certain transfers of existing generation facilities 
and certain holding companies’ acquisitions of facilities with a value in excess of $10 million. FERC’s regulations implementing 
Section 203 of the FPA provide blanket authorizations for certain types of transactions, including acquisitions by holding companies 
that are holding companies solely due to their ownership, directly or indirectly, of one or more QFs, EWGs and FUCOs, to acquire 
additional QFs, EWGs or FUCOs, or the securities of additional QFs, EWGs and FUCOs without prior FERC approval.

FERC Regulation of Qualifying Facilities

Cogeneration and certain small power production facilities are eligible to be QFs under PURPA, provided that they meet 
certain  power  and  thermal  energy  production  requirements,  and  efficiency  standards.  QF  status  provides  an  exemption  from 
PUHCA 2005 and grants certain other benefits to the QF, including, in some cases, the right to sell power to utilities at the utilities’ 
avoided cost (“PURPA put”). Certain types of sales by QFs are also exempt from FERC regulation of wholesale sales of the QFs’ 
power output. QFs are also exempt from most state laws and regulations. To be a QF, a cogeneration power plant must produce 
power and useful thermal energy for an industrial or commercial process, or heating or cooling applications in certain proportions 
to the power plant’s total energy output, and must meet certain efficiency standards.

29

An electric utility may be relieved of the mandatory purchase obligation under the PURPA put if FERC determines that 

such QFs have access to a competitive wholesale power market.

Station Power Ruling

On August 30, 2010, FERC issued an order reversing its prior rulings relating to a generator’s self-supply of station power 
in the markets administered by CAISO. In the August 2010 order, the FERC concluded that it does not have jurisdiction to determine 
when a generator self-supplies station power and when the generator purchases its power needs through a retail sale. The FERC 
found that its jurisdiction covers only the transmission of station power and the states have exclusive jurisdiction to determine 
when the use of station power results in a retail sale. Calpine and several other generators filed an appeal of the FERC’s decision. 
On December 18, 2012, the D.C. Circuit issued a decision in favor of the FERC. Although the decision concerns CAISO’s treatment 
of station power, the decision is applicable to all ISOs and RTOs and could result in our power plants paying more for station 
power service in the future.

FERC Enforcement Authority

FERC has civil penalty authority over violations of any provision of Part II of the FPA, as well as any rule or order issued 
thereunder. FERC is authorized to assess a maximum civil penalty of $1 million per violation for each day that the violation 
continues. The FPA also provides for the assessment of criminal fines and imprisonment for violations under Part II of the FPA. 
This penalty authority was enhanced in EPAct 2005. With this expanded enforcement authority, violations of the FPA and FERC’s 
regulations could potentially have more serious consequences than in the past.

NERC Compliance Requirements

Pursuant to EPAct 2005, NERC has been certified by FERC as the Electric Reliability Organization to develop and 
oversee the enforcement of electric system reliability standards applicable throughout the U.S., which are subject to FERC review 
and approval. FERC-approved reliability standards may be enforced by FERC independently, or, alternatively, by NERC and the 
regional reliability organizations with frontline responsibility for auditing, investigating and otherwise ensuring compliance with 
reliability standards, subject to FERC oversight. Monetary penalties of up to $1 million per day per violation may be assessed for 
violations of the reliability standards. Certain electric reliability standards which apply to us as a generator owner, generator 
operator or marketer of power (purchasing and selling entity) are effective and mandatory. In addition, the regional reliability 
organizations have the ability to formulate supplemental reliability standards to apply in their specific regions, which may be more 
stringent than the NERC reliability standards. We comply with different reliability standards, requirements and procedural rules 
in each region in which we operate. FERC has approved many NERC and regional reliability standards. It is expected that additional 
or modified reliability standards will be approved by FERC in the coming years, requiring us to take additional steps to remain 
fully compliant.

Regional and State Regulation of Power

The following summaries of the regional rules and regulations affecting our business focus on the West, Texas and North 
because these are the regions in which we have the most significant portfolios of power plants. While we provide a brief overview 
of the primary regional rules and regulations affecting our power plants located in other regions of the country, we do not provide 
an in-depth discussion of these rules and regulations because our asset portfolio in those regions is not as significant. All power 
plant and MW data is reported as of December 31, 2012.

West

We have 24 natural gas-fired power plants, including 2 under construction (1 new power plant and 1 expansion of an 
existing power plant), with the capacity to generate a total of 6,026 MW in the WECC NERC region, which extends from the 
Rocky Mountains westward. In addition, we own and operate 15 geothermal turbine-based power plants located in The Geysers 
region of northern California capable of producing a total of 725 MW. The majority of these power plants are located in California, 
in the CAISO region; however, we also own one power plant in both Arizona and Oregon.

CAISO is responsible for ensuring the safe and reliable operation of the transmission grid within the bulk of California 
and providing open, nondiscriminatory transmission services. Pursuant to a FERC-approved tariff, CAISO has certain abilities to 
impose penalties on market participants for violations of its rules. CAISO maintains various markets for wholesale sales of power, 
differentiated by time and type of electrical service, into which our subsidiaries may sell power from time to time. These markets 
are subject to various controls, such as price caps and mitigation of bids when transmission constraints arise. The controls and the 
markets themselves are subject to regulatory change at any time. CAISO runs integrated day-ahead and real-time markets for 
energy  and  ancillary  services.  The  energy  markets  include  centralized,  day-ahead  and  real-time  markets  for  energy,  a  nodal 
transmission  congestion  management  model  that  results  in  locational  marginal  pricing  at  each  generation  location,  financial 

30

congestion hedging instruments, a centralized day-ahead commitment process and an energy bid cap of $1,000 per MWh. The 
locational marginal pricing market design is intended to reward and encourage generation resources on favorable grid locations, 
such as some of the locations of our power plants.

Prior to May 7, 2012, our Sutter power plant, which is a 578 MW natural gas-fired, combined-cycle power plant, had no 
contracts for its output in 2012. In late 2011, we determined that the power plant will be uneconomic and may have to be shut 
down absent incremental compensation. Consequently, on November 22, 2011, we submitted a request to the CAISO to compensate 
us for our Sutter power plant under a provision of CAISO’s current tariff that is intended to avoid retirement of needed generating 
units. Under this tariff provision, the Capacity Procurement Mechanism (“CPM”) allows the CAISO to compensate assets that 
are needed in the future, but are not currently receiving sufficient revenues to sustain operation. On March 29, 2012, the CPUC 
issued a resolution ordering California’s three IOUs to negotiate to enter into contracts with us and on May 7, 2012, we announced 
that contracts were executed with California’s three IOUs for the purchase of resource adequacy from our Sutter power plant for 
the period from July through December 2012.

The CPUC and CAISO continue to evaluate long-term capacity procurement policies and products for the California 
power market. With the expectation of significant increases in renewables, both agencies are evaluating the need for generation 
flexibility  attributes  such  as  dispatchability,  ramping  and  load  following.  In  addition,  both  agencies  may  consider  forward 
procurement  mechanisms  or  obligations.  In  this  light,  the  CAISO  filed  a  request  at  the  FERC  for  a  backstop  mechanism  on 
December 12, 2012, which, if approved by FERC, will allow the CAISO to look forward five years and compensate generation 
units that are needed for capacity or generation attributes, but would otherwise retire. This proposal is similar to that which was 
filed by the CAISO with the FERC early in 2012 in an attempt to retain our Sutter power plant. In January 2013, we protested the 
CAISO filing, raising concerns with the CAISO’s approach and suggesting that a forward procurement obligation and central 
capacity clearing mechanism would be superior to the CAISO’s proposal. The CPUC continues to review its resource adequacy 
and long-term procurement planning and may include forward procurement in the coming months.

A recently implemented CPUC settlement changes significant aspects of policy towards California QFs, including our 
non-renewable QF facilities. The settlement resolves issues related to QFs under existing QF contracts and establishes new energy 
pricing options for QFs under QF contracts, including the option to shed QF host and efficiency obligations and become dispatchable, 
and specifies mechanisms for the California IOUs to procure both existing combined heat and power (“CHP”) that is not otherwise 
under contract and new CHP. Pursuant to the QF Settlement, we have converted two of our former QFs to dispatchable non-QF 
units, and we offered some of our resources into the IOUs’ recent CHP solicitations. The IOUs selected our CHP offers for our 
Los Medanos Energy Center and Gilroy Cogeneration Plant and the transactions are now awaiting regulatory approval. The impact 
of the larger CHP settlement has been positive to Calpine.

Our power plants located outside of California either sell power into the markets administered by CAISO or sell power 
through bilateral transactions outside CAISO. Those transactions occurring outside CAISO are subject to FERC regulation and 
oversight, but they are not subject to CAISO rules and regulations.

Texas

We have 13 natural gas-fired power plants in the TRE NERC region with the capacity to generate a total of 8,014 MW, 
all of which are physically located in the ERCOT market. ERCOT is the ISO that manages approximately 85% of Texas’ load and 
an electric grid covering about 75% of the state, overseeing transactions associated with Texas’ competitive wholesale and retail 
power markets. FERC does not regulate wholesale sales of power in ERCOT. The PUCT exercises regulatory jurisdiction over 
the rates and services of any electric utility conducting business within Texas. Our subsidiaries that own power plants in Texas 
have power generation company status at the PUCT, and are either EWGs or QFs and are exempt from PUCT rate regulation. 
ERCOT ensures resource adequacy through an energy-only model rather than the capacity-based resource adequacy model that 
is more common among RTOs or ISOs in the Eastern Interconnect. In ERCOT, there is a market price cap for energy and capacity 
purchased by ERCOT. Under certain market conditions, the offer cap could be lower. Our subsidiaries are subject to the offer cap 
rules, but only for sales of power and capacity services to ERCOT.

The  PUCT  continues  its  very  deliberative  approach  of  considering  design  changes  aimed  at  improving  the  ERCOT 
market’s scarcity pricing signals. Of the two rulemakings undertaken in April 2012, the project dealing with near term system-
wide offer cap (“SWOC”) resulted in the offer cap being raised from $3,000/MWh to $4,500/MWh and took effect on August 1, 
2012. In October 2012, the PUCT approved other changes including raising the SWOC beginning June 1, 2013 to $5,000/MWh, 
to $7,000/MWh on June 1, 2014 and finally to $9,000/MWh on June 1, 2015. In addition, the Peaker Net Margin (“PNM”) will 
increase from $262,500 to $300,000 and in subsequent years it will be calculated at three-times the cost of new entry based on a 
simple-cycle natural gas turbine. If the PNM is exceeded in any given year, the SWOC is automatically lowered for the remainder 
of the year to the Low System Offer Cap (“LCAP”). The LCAP will change to the higher of $2,000/MWh, an increase from $500/
MWh, or 50 times the daily Houston Ship Channel natural gas price index. Given the potential liquidity impacts of possibly higher 

31

offer caps, ERCOT stakeholders are considering the associated market credit and collateralization design changes in an effort to 
keep pace with the potential increase in the market’s risk exposure. With these changes and proposed changes, we expect higher 
prices when scarcity pricing conditions occur which could have a positive impact on our Commodity Margin.

The Brattle Group’s (“Brattle”) June 1, 2012 release of its report on investment incentives and resource adequacy in the 
ERCOT market laid a solid foundation for continuing deliberation by the PUCT, ERCOT and market participants on two threshold 
issues. The first is whether the ERCOT region should have a mandated annual planning reserve margin or simply a reliability 
reserve margin target that is allowed to float in concert with the dynamics of the current energy-only market construct. The second 
threshold issue for the PUCT is to decide the best one of the five resource adequacy policy options offered by Brattle. At the 
request of the PUCT, Brattle prepared two separate resource adequacy proposals for its consideration: a modified energy-only 
proposal  and  the  Texas  Capacity  Market,  a  centralized  forward  capacity  market  mechanism  similar  to  PJM’s.  Calpine  filed 
comments with the PUCT in support of the Texas Capacity Market concept. In addition, Brattle provided a demand response 
analysis that shows how much and how quickly price responsive demand can penetrate the ERCOT market. On October 25, 2012, 
the PUCT held a workshop to discuss the two Brattle proposals and received Brattle’s demand response analysis. The PUCT has 
not voted on either proposal or established a timetable for further consideration of the proposals or whether to adopt a reserve 
margin requirement versus continuing with the current reserve margin target. A decision from the PUCT is expected in 2013. We 
continue to support the development of a centralized forward capacity market, which, depending on implementation, we view as 
superior to any energy-only mechanism, to ensure ERCOT meets its reliability objective under any market conditions. As these 
proceedings are ongoing, we cannot predict what the ultimate impact may be nor the impact on our financial condition, results of 
operations or cash flows.

The PUCT continues to consider other proposals to improve proper wholesale price formation. At the request of the 
PUCT, ERCOT has been working to develop a proposal for an operating reserves demand curve for PUCT and ERCOT stakeholder 
consideration. The key feature of the proposal is a pricing methodology based on the Value of Lost Load (“VOLL”) and Loss of 
Load Probability (“LOLP”). The result of this calculation is a value that is dependent on the amount of available operating reserves, 
but added to the system-wide clearing price, without regard to whether the system is in scarcity conditions. It is possible some 
type of operating reserves demand curve proposal could be in place by summer 2013. We support the evaluation of this concept, 
but unlike a centralized forward capacity market, we do not view this concept as a solution for long-term resource adequacy in 
ERCOT.  We cannot predict, at this time, all of the details of a prospective proposal or the ultimate impact on our financial condition, 
results of operations or cash flows.

ERCOT’s  planning  function  has  undertaken  two  very  significant  study  efforts,  both  of  which  may  have  important 
implications for the region’s resource adequacy metrics and ultimately the value of power in the ERCOT market. A Loss of Load 
Expectation (“LOLE”) study has been conducted by a vendor and the final draft was delivered to stakeholders on January 18, 
2013. The study will show for one occurrence of the loss of firm load in a 10-year period what annual planning reserve margin 
percentage is required for resource planning. The study shows that a planning reserve margin is required that is materially greater 
than the currently approved 13.75% if the experienced weather and loading patterns of the summer of 2011 are included in the 
study’s model runs. Initial stakeholder reaction was to endorse the study’s methodology as well as to include the weather impacts 
of summer 2011. The range of possible annual planning reserve values supported by the study that the ERCOT Board of Directors 
might consider is from 15.8% to 18.9%. The study results will be further vetted with stakeholders and it is expected that the ERCOT 
Board of Directors could take action in changing the annual planning reserve margin at its March 2013 meeting. The second study 
effort will estimate the VOLL. That study is expected to be completed in mid-2013 and should provide meaningful estimates for 
the value of firm customer load in the various load categories when firm load shedding is necessary in emergency conditions. The 
current SWOC is $4,500/MWh and will escalate to $9,000/MWh in 2015, as discussed above, and the VOLL study may shed 
some light on whether the SWOC is high enough to approximate the VOLL.

ERCOT  implemented  a  nodal  market  structure  on  December 1,  2010. A  nodal  market  structure  results  in  locational 
marginal pricing at each generation location rather than establishing pricing in four zones as was done prior to December 1, 2010. 
The implementation costs for the ERCOT central operating systems for nodal were paid by generating resources through a MWh-
based surcharge. The Nodal Implementation Surcharge was levied at a rate of $0.375/MWh of all energy generated and was 
terminated in January 2013 with the retirement of the debt coverage of ERCOT’s nodal costs.

The Sunset Review Process, implemented by the Texas Legislature in 1977, is the regular assessment of the need for a 
state agency to exist and to consider new and innovative changes to improve each agency’s operations and activities. The Sunset 
Review Process works by setting a date on which an agency will be abolished unless legislation is passed to continue its functions. 
While significant changes were proposed by the Sunset Advisory Commission, the legislation did not become law. Therefore, the 
Sunset Advisory Commission has undertaken another review of these agencies and any resulting legislation will be considered in 
the 2013 legislative session. We cannot predict which changes, if any, will be placed into legislation and ultimately reach final 
passage. We will continue to participate in these processes where we anticipate any potential impact on our business.

North

regions.

We have a total of 30 power plants with 7,320 MW of peaking capacity located in the RFC, NPCC and MRO NERC 

We have 19 operating power plants with the capacity to generate a total of 4,491 MW in Eastern PJM. In addition, we 
have one operating power plant, with the capacity to generate 503 MW, located in Western PJM. Eastern PJM and Western PJM 
are both located in the RFC NERC region. PJM operates wholesale power markets, a locationally based capacity market, a forward 
capacity market and ancillary service markets. PJM also performs transmission planning for the region.

Certain states in the PJM market region, particularly New Jersey and Maryland, have taken actions that could impact the 
PJM capacity market. In New Jersey, legislation enacted in 2011 required the New Jersey Board of Public Utilities (“BPU”) to 
issue a request for proposals (“RFP”) for new generation. As a result of the RFP, the BPU directed New Jersey’s four public utilities 
to enter into standard offer capacity agreements with the winning generators for new capacity to be built in New Jersey. Several 
entities have appealed the BPU’s order directing the public utilities to enter into long-term contracts with those generators. The 
appeal process is continuing. Also, on February 9, 2011, we joined a group of generators and utilities in filing a complaint in 
federal district court challenging the constitutionality of the New Jersey legislation. On September 28, 2012, the judge in the 
proceeding denied all Motions for Summary Judgment. Discovery is continuing with a trial expected to be held in late March to 
early April 2013.

On September 29, 2011, the Maryland Public Service Commission (“MPSC”) issued a “Notice of Approval of Request 
for Proposals for New Generation to be Issued by Maryland Electric Distribution Companies” (the “Notice”). The Notice required 
the state’s IOUs to issue RFPs for up to 1,500 MW of capacity. The Notice specifies that proposals must be for new natural gas-
fired capacity capable of delivery into the PJM Southwest Mid-Atlantic Area Council (“SWMAAC”) delivery area. On April 12, 
2012, the MPSC issued a further order in this proceeding directing certain Maryland IOUs located in the SWMAAC area to enter 
into a contract for differences with CPV Maryland, LLC (“CPV”), a generation developer that is currently developing a 661 MW 
natural gas-fired, combined-cycle generation plant in SWMAAC. The facility’s scheduled COD is June 1, 2015. In May 2012, 
we filed with the Circuit Court of Baltimore County, Maryland a Petition for Review of the MPSC’s order, asking the court to 
review the order and declare it invalid. Several other parties filed similar appeals. The appeals have been consolidated, but the 
case has been suspended pending resolution of certain terms in the contracts between the IOUs and CPV. In a separate action, 
several generators have filed a complaint in federal district court challenging the constitutionality of the MPSC’s actions. That 
case is expected to go to trial in late February 2013.

At the FERC level, PJM has taken action to strengthen the Minimum Offer Price Rule (“MOPR”) in its tariff. PJM’s 
tariff changes are intended to address the negative implications from these state actions. The FERC issued an order in April 2011 
approving amendments to PJM’s MOPR tariff provisions. The FERC order is currently on appeal before the U.S. Court of Appeals 
for the Third Circuit. In December 2012, PJM filed further amendments to the MOPR that are intended to make the MOPR process 
more transparent and objective. On February 5, 2013, the FERC asked PJM to provide additional information about its proposal. 
While unclear, given the current timing of PJM’s response and a subsequent FERC decision, it is still possible for the changes to 
be in effect for the 2016/2017 PJM Reliability Pricing Model base residual auction, to be held on May 13-17, 2013.

We have a total of eight natural gas-fired power plants with the capacity to generate a total of 1,448 MW in the NPCC 
NERC region. Five of these power plants are located in New York. NYISO manages the transmission system in New York and 
operates the state’s wholesale power markets. NYISO manages both day-ahead and real-time energy markets using a locationally 
based marginal pricing mechanism that pays each generator the zonal marginally accepted bid price for the energy it produces.

Our remaining U.S.-based power plant in the NPCC NERC region is located in Maine. ISO-NE is the RTO for Connecticut, 
Maine, Massachusetts, New Hampshire, Rhode Island and Vermont. ISO-NE has broad authority over the day-to-day operation 
of  the  transmission  system  and  operates  a  day-ahead  and  real-time  wholesale  energy  market,  a  forward  capacity  market  and 
ancillary services markets. ISO-NE also provides for regional transmission planning.

We also have 50% ownership interests in two Canadian power plants, with the total capacity to generate 1,088 MW (544 
MW net attributable to Calpine), located in the NPCC NERC region in Ontario, Canada. The Whitby cogeneration facility is a 50 
MW facility located in Whitby, Ontario and the Greenfield Energy Centre is a 1,038 MW facility located in Courtright, Ontario. 
The Independent Electricity System Operator (“IESO”) of Ontario operates the Province’s wholesale power markets and directs 
the operation and ensures reliability of the IESO controlled grid. Hydro-One owns and operates the transmission system in Ontario, 
which is regulated by the Ontario Energy Board.

We have two natural gas-fired power plants with the capacity to generate a total of 878 MW operating within the MRO 
NERC region. MISO manages competitive locationally based wholesale day-ahead, real-time energy and ancillary services markets. 
MISO’s Resource Adequacy model requires load serving entities to account for capacity obligations under Module E of the MISO 

33

tariff. MISO currently conducts a monthly voluntary capacity auction to help purchasers find suppliers with capacity to meet their 
incremental capacity needs. In 2013, MISO will complete a transition to a new capacity market design. Among other things, the 
new design will move MISO from a monthly capacity product to an annual capacity product, and implement annual auctions, 
although market participation will remain voluntary for all load-serving entities. We do not believe that this new market design 
will have a material impact on our business.

Southeast

We have one operating natural gas-fired power plant with the capacity to generate 1,134 MW located in the SPP NERC 
region. SPP is an RTO approved by FERC that provides independent administration of the electric power grid. SPP currently 
manages an energy-only location based real-time wholesale energy market. This market provides both nominal load-following 
and transmission constraint relief. In October 2012, the FERC approved tariff changes to enact SPP’s proposed “Day 2” wholesale 
energy markets. SPP, which currently conducts a basic real-time nodal balancing market, will expand its market to a suite of new 
markets that will include centralized, security-constrained economic unit commitment with both a financially-binding, day-ahead 
nodal energy market and a physically-binding, real-time nodal energy market, a congestion management market using Transmission 
Congestion Rights, consolidate existing Balancing Areas and implement ancillary services markets for regulation and reserves. 
SPP will also have the authority to commit generation for reliability purposes and guarantee cost recovery for such units that are 
otherwise uneconomic. SPP will also have virtual load and generation markets that will permit hedging and speculation and plans 
to accommodate demand-side resource market participation. SPP did not propose any type of resource adequacy or capacity market 
in its new market design. We believe the market structure is generally beneficial to our Oneta Energy Center which is located in 
the SPP region.

We have nine natural gas-fired power plants with the capacity to generate a total of 4,102 MW operating within the SERC 
and the FRCC NERC regions. Opportunities to negotiate bilateral, individual contracts and long-term transactions with IOUs, 
municipalities and cooperatives exist within these regions. In addition to entering into bilateral transactions, there is a limited 
opportunity to sell into the short-term market.

In the Entergy sub-region, MISO has replaced SPP as the designated Independent Coordinator of Transmission. In this 
capacity, the Independent Coordinator of Transmission provides oversight of the Entergy transmission system. Entergy and MISO 
continue to move forward with their proposal to transfer functional control of Entergy’s transmission system to MISO by December 
2013.  Entergy  has  received  conditional  approvals  for  change  of  control  applications  filed  with  the Arkansas  Public  Service 
Commission, the City of New Orleans, the Louisiana Public Service Commission, the Mississippi Public Service Commission, 
and the PUCT. We support Entergy membership in an RTO as soon as possible.

Other State Regulation of Power

State Public Utility Commissions, or PUC(s), have historically had broad authority to regulate both the rates charged by, 
and the financial activities of, electric utilities operating in their states and to promulgate regulation for implementation of PURPA. 
Since all of our affiliates are either QFs or EWGs, none of our affiliates are currently subject to direct rate regulation by a state 
PUC. However, states may assert jurisdiction over the siting and construction of power generating facilities including QFs and 
EWGs and, with the exception of QFs, over the issuance of securities and the sale or other transfer of assets by these facilities. In 
California, for example, the CPUC was required by statute to adopt and enforce maintenance and operation standards for power 
plants “located in the state,” including EWGs but excluding QFs, for the purpose of ensuring their reliable operation. As the owner 
and operator of power plants in California, our subsidiaries are subject to the power plant maintenance and operation standards 
and the general duty standards that are enforced by the CPUC.

State PUCs also maintain extensive control over the procurement of wholesale power by the utilities that they regulate. 
Many of these utilities are our customers, and agreements between us and these counterparties often require approval by state 
PUCs. For example, in California, the CPUC determines how much new generation can be purchased by the IOUs, and shapes 
the rules of the IOUs’ requests for offers. In addition, the CPUC determines the rules of California’s Resource Adequacy program. 
The Resource Adequacy program is currently based on a loosely structured year- and month-ahead bilateral capacity market.

Regulation of Transportation and Sale of Natural Gas

Since the majority of our power generating capacity is derived from natural gas-fired power plants, we are broadly 
impacted by federal regulation of natural gas transportation and sales. Furthermore, our two natural gas transportation pipelines 
in Texas are subject to dual jurisdiction by the FERC and the Texas Railroad Commission. These pipelines are intrastate pipelines 
within the meaning of Section 2(16) of the Natural Gas Policy Act (“NGPA”). FERC regulates the rates charged by these pipelines 
for transportation services performed under Section 311 of the NGPA, and the Texas Railroad Commission regulates the rates and 
services provided by these pipelines as gas utilities in Texas.

34

We also operate a proprietary pipeline system in California, which is regulated by the U.S. Department of Transportation 
and the Pipeline and Hazardous Materials Safety Administration with regard to safety matters. Additionally, some of our power 
plants own and operate short pipeline laterals that connect the natural gas-fired power plants to the North American natural gas 
grid. Some of these laterals are subject to state and/or federal safety regulations.

Under the Natural Gas Act (“NGA”), the NGPA and the Outer Continental Shelf Lands Act, the FERC is authorized to 
regulate pipeline, storage and liquefied natural gas, or LNG, facility construction; the transportation of natural gas in interstate 
commerce; the abandonment of facilities; and the rates for services. The FERC is also authorized under the NGA to regulate the 
sale of natural gas at wholesale.

The FERC has civil penalty authority for violations of the NGA and NGPA, as well as any rule or order issued thereunder. 
The FERC’s regulations specifically prohibit the manipulation of the natural gas markets by making it unlawful for any entity in 
connection with the purchase or sale of natural gas, or the purchase or sale of transportation service under the FERC’s jurisdiction, 
to engage in fraudulent or deceptive practices. Similar to its penalty authority under the FPA described above, the FERC is authorized 
to assess a maximum civil penalty of $1 million per violation for each day that the violation continues. The NGA and NGPA also 
provide for the assessment of criminal fines and imprisonment time for violations.

Federal Regulation of Futures and Other Derivatives

CFTC Regulation of Futures Transactions

The CFTC has regulatory oversight of the futures markets, including trading on NYMEX for energy, and licensed futures 
professionals such as brokers, clearing members and large traders. In connection with its oversight of the futures markets and 
NYMEX, the CFTC regularly investigates market irregularities and potential manipulation of those markets. Recent laws also 
give the CFTC certain powers with respect to broker-type markets referred to as “exempt commercial markets” or ECMs, including 
the Intercontinental Exchange. The CFTC monitors activities in the OTC, ECM and physical markets that may be undertaken for 
the purpose of influencing futures prices. With respect to ECMs, the CFTC exercises only light-handed regulation primarily related 
to  trade  reporting,  price  dissemination  and  record  retention  (including  retention  of  fraudulent  claims  and  allegations). Thus, 
transactions executed on an ECM generally are not regulated directly by the CFTC. However, the CFTC may make special calls 
of market participants in the ECM and ECM transactions have come under the CFTC’s scrutiny during investigations of fraud 
and  manipulation  in  which  the  CFTC  has  broadly  applied  its  statutory  authority  to  punish  persons  who  are  alleged  to  have 
manipulated, or attempted to manipulate, the price of any commodity in interstate commerce or for future delivery. Moreover, 
while ECM transactions are not required to be cleared, if they are cleared, such cleared ECM transactions would be subject to 
regulation by the CFTC. We also expect the CFTC’s powers and oversight to be increased by the Dodd-Frank Act. However, as 
discussed below, the extent of such increased powers and oversight, and its effect on ECM transactions, if any, is not yet certain. 

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010

CFTC Regulation of Derivatives Transactions

The Dodd-Frank Act, which was signed into law on July 21, 2010, contains a variety of provisions designed to regulate 
financial markets, including credit and derivatives transactions. Title VII of the Dodd-Frank Act addresses regulatory reform of 
the OTC derivatives market in the U.S. and significantly changes the regulatory framework of this market. Certain Title VII 
regulations have been finalized and are effective though some regulations remain subject to a delayed compliance schedule. Other 
key regulations have not been finalized as of this time or remain in draft form. Until all of these regulations have been finalized, 
the extent to which the provisions of Title VII might affect our derivatives activities cannot be completely known. A number of 
features in the legislation may impact our existing business. One of these is the requirement for central clearing of many OTC 
derivative transactions with clearing organizations. Moreover, whereas our OTC transactions have traditionally been negotiated 
on a bilateral basis, including the collateral arrangements thereunder, they now may be subject to the collateral and margining 
procedures of the clearing organization. Certain end-users may be able to benefit from an exception which would exempt them 
from mandatory clearing requirements. If the derivatives transactions which we enter into are determined to be subject to mandatory 
clearing requirements, we will seek to comply with the regulatory requirements in order to benefit from the end-user exception. 
Uncleared OTC derivatives transactions under the Dodd-Frank Act will also be subject to collateral and margining procedures 
established by CFTC regulation. These Title VII regulations have not, as of the date of this Report, been finalized. Other features 
of the Dodd-Frank Act which will have an impact on our derivative activities include trade reporting and trade execution. The 
effect of the Dodd-Frank Act on traditional dealers and market-makers as well as the consequential effect on market liquidity and, 
hence, pricing is uncertain. Nevertheless, we expect to be able to continue to participate in financial markets for our derivative 
transactions.

Some of the key regulatory rulemakings regarding the definition of specific entity designations and the swap definition 
rules for the Dodd-Frank Act were finalized in the second and third quarters of 2012. The CFTC also recently issued several no-

35

action letters, interpretations and an exemptive order impacting the implementation schedule and interpretations of key provisions 
in the CFTC’s Dodd-Frank Act implementation rules. We have reviewed our derivative activities over a one month survey period, 
as a proxy for future activity, and our intended future activities, and have determined that we are not a swap dealer as defined 
under the CFTC’s final entity definition rule and, therefore, are not required to register as a swap dealer. We have established an 
internal working group for a thorough and ongoing evaluation of the impact and timing of these recent rulemakings on our operations 
as a non-swap dealer; however, it is difficult to fully assess the ultimate impact of the Dodd-Frank Act on us until all rulemakings 
are finalized and implemented.

While we are closely monitoring this rulemaking process from the CFTC (including related no-action relief, interpretations 
and orders), we have reviewed and assessed the impact of the CFTC’s Title VII regulations on our business and related processes, 
and we have adjusted our internal procedures where necessary to comply with the applicable statutory law and related Title VII 
regulations which are effective at this time. We will continue to monitor all relevant developments and rulemaking initiatives, and 
we expect to successfully implement any new applicable requirements. At this time, we cannot predict the impact or possible 
additional costs to us related to the implementation of, or compliance with, the potential future requirements under the Dodd-
Frank Act.

Other provisions

The Dodd-Frank Act also requires regulatory agencies, including the SEC, to establish regulations for implementation 
of many of the provisions of the Dodd-Frank Act. In August 2012, as mandated by the Dodd-Frank Act, the SEC adopted final 
rules requiring resource extraction issuers to report, on an annual basis, any payments made by the issuer to the U.S. Federal 
Government or a foreign government for the purpose of the commercial development of oil, natural gas or minerals. The annual 
disclosure filing of these payments must be made with the SEC for fiscal years ending after September 30, 2013 (i.e. beginning 
with our fiscal year ending December 31, 2013). For calendar year end companies, like Calpine, the initial information reporting 
period runs from October 1, 2013 through December 31, 2013, and must be provided to the SEC by May 30, 2014. Our report 
will  include  information  about  the  total  amount  of  payments  made  to  the  U.S.  Federal  Government  in  conjunction  with  our 
geothermal leases from which we extract steam for our Geysers Assets.

The Dodd-Frank Act contains provisions to improve transparency and accountability concerning the supply of certain 
minerals, known as conflict minerals (namely tin, tantalum, tungsten or gold), originating from the conflict zones of the Democratic 
Republic of Congo (“DRC”) and adjoining countries. In August 2012, as mandated by the Dodd-Frank Act, the SEC adopted final 
rules requiring all issuers that file reports with the SEC to report, on an annual basis, supply chain and sourcing information for 
companies that use conflict minerals mined from the DRC and adjoining countries in their products. These new requirements will 
require due diligence efforts in fiscal 2013, with initial disclosure requirements beginning in May 2014. Based on our preliminary 
analysis, we do not believe that any of our products contain conflict minerals; however, our assessment process to determine 
whether conflict minerals are necessary to the functionality or production of any of our products is not complete.

Geothermal Operations

The focus on induced seismicity caused by hydro-fracturing associated with natural gas and geothermal exploration and 
production could cause government entities or agencies to more stringently regulate that activity and such regulation could impact 
the exploration, development and operation of geothermal power plants, including our Geysers Assets.

EMPLOYEES

At December 31, 2012, we employed 2,151 full-time employees, of whom 158 were represented by collective bargaining 
agreements. We have 103 employees represented by collective bargaining agreements which expire within one year. We have 
never experienced a work stoppage or strike.

Item 1A. Risk Factors

Commercial Operations

Our financial performance is impacted by price fluctuations in the wholesale power and natural gas markets and other 

market factors that are beyond our control.

Market prices for power, generation capacity, ancillary services, natural gas and fuel oil are unpredictable and fluctuate 
substantially. Unlike most other commodities, power can only be stored on a very limited basis and generally must be produced 
concurrently with its use. As a result, power prices are subject to significant volatility due to supply and demand imbalances, 
especially in the day-ahead and spot markets. Long- and short-term power and natural gas prices may also fluctuate substantially 
due to other factors outside of our control, including:

36

• 

• 

• 

increases and decreases in generation capacity in our markets, including the addition of new supplies of power as a 
result of the development of new power plants, expansion of existing power plants or additional transmission capacity;

changes in power transmission or fuel transportation capacity constraints or inefficiencies;

power supply disruptions, including power plant outages and transmission disruptions;

•  Heat Rate risk;

•  weather conditions;

• 

• 

• 

• 

• 

• 

• 

• 

quarterly and seasonal fluctuations;

coal prices;

changes in the demand for power or in patterns of power usage, including the potential development of demand-side 
management tools and practices;

development of new fuels or new technologies for the production or storage of power;

federal and state regulations and actions of the ISOs;

federal and state power, market and environmental regulation and legislation, including mandating an RPS or creating 
financial incentives, each resulting in new renewable energy generation capacity creating oversupply;

changes in prices related to RECs; and

changes in capacity prices and capacity markets.

These factors have caused our operating results to fluctuate in the past and will continue to cause them to do so in the 

future.

Our revenues and results of operations depend on market rules, regulation and other forces beyond our control.

Our revenues and results of operations are influenced by factors that are beyond our control, including:

• 

• 

• 

• 

• 

• 

rate caps, price limitations and bidding rules imposed by ISOs, Regional Transmission Organizations and other 
market regulators that may impair our ability to recover our costs and limit our return on our capital investments;

regulations promulgated by the FERC and the CFTC;

sufficient liquidity in the forward commodity markets to conduct our hedging activities;

some of our competitors (mainly utilities) receive entitlement-guaranteed rates of return on their capital investments, 
with returns that exceed market returns and may impact our ability to sell our power at economical rates;

structure and operating characteristics of our capacity markets such as our PJM capacity auctions and our NYISO 
markets; and

regulations and market rules related to our RECs.

Accounting for our hedging activities may increase the volatility in our quarterly and annual financial results.

We engage in commodity-related marketing and price-risk management activities in order to economically hedge our 
exposure to market risk with respect to power sales from our power plants, fuel utilized by those assets and emission allowances. 
We generally attempt to balance our fixed-price physical and financial purchases, and sales commitments in terms of contract 
volumes and the timing of performance and delivery obligations through the use of financial and physical derivative contracts. 
These derivatives are accounted for under U.S. GAAP, which requires us to record all derivatives on the balance sheet at fair value 
unless they qualify for, and we elect, the normal purchase normal sale exemption. In order to simplify our reporting, we elected 
to discontinue the application of hedge accounting treatment during the first quarter of 2012 for all commodity derivatives, including 
the remaining commodity derivatives previously accounted for as cash flow hedges. Accordingly, prospective changes in fair value 
from the date of this election are reflected in unrealized mark-to-market activity on our Consolidated Statements of Operations 
and could create more volatility in our earnings. The fair value of our commodity derivative instruments residing in AOCI during 
the previous application of hedge accounting was reclassified to earnings during 2012 as the related economic transactions affected 
earnings or the forecasted transaction became probable of not occurring. As a result, we are unable to accurately predict the impact 
that our risk management decisions may have on our quarterly and annual financial results.

37

The use of hedging agreements may not work as planned or fully protect us and could result in financial losses.

We typically enter into hedging agreements, including contracts to purchase or sell commodities at future dates and at 
fixed prices, in order to manage our commodity price risks. These activities, although intended to mitigate price volatility, expose 
us to other risks. When we sell power forward, we may be required to post significant amounts of cash collateral or other credit 
support to our counterparties, and we give up the opportunity to sell power at higher prices if spot prices are higher in the future. 
Further, if the values of the financial contracts change in a manner that we do not anticipate, or if a counterparty fails to perform 
under a contract, it could harm our financial condition, results of operations and cash flows.

We do not typically hedge the entire exposure of our operations against commodity price volatility. To the extent we do 
not hedge against commodity price volatility, our financial condition, results of operations and cash flows may be diminished 
based upon adverse movement in commodity prices.

Our ability to enter into hedging agreements and manage our counterparty credit risk could adversely affect us.

Our  customer  and  supplier  counterparties  may  experience  deteriorating  credit.  These  conditions  could  cause 
counterparties in the natural gas and power markets, particularly in the energy commodity derivative markets that we rely on for 
our hedging activities, to withdraw from participation in those markets. If multiple parties withdraw from those markets, market 
liquidity  may  be  threatened,  which  in  turn  could  adversely  impact  our  business  and  create  more  volatility  in  our  earnings. 
Additionally, these conditions may cause our counterparties to seek bankruptcy protection under Chapter 11 or liquidation under 
Chapter 7 of the Bankruptcy Code. Our credit risk may be exacerbated to the extent collateral held by us cannot be realized or is 
liquidated at prices not sufficient to recover the full amount of the exposure due to us. There can be no assurance that any such 
losses or impairments to the carrying value of our financial assets would not materially and adversely affect our financial condition, 
results of operations and cash flows.

Competition could adversely affect our performance.

The power generation industry is characterized by intense competition, and we encounter competition from utilities, 
industrial companies, marketing and trading companies and other independent power producers. In addition, many states are 
implementing  or  considering  regulatory  initiatives  designed  to  increase  competition  in  the  domestic  power  industry.  This 
competition  has  put  pressure  on  power  utilities  to  lower  their  costs,  including  the  cost  of  purchased  power,  and  increasing 
competition in the supply of power in the future could increase this pressure. In addition, construction during the last decade has 
created excess power supply and higher reserve margins in the power trading markets, putting downward pressure on prices.

In  certain  situations,  our  PPAs  and  other  contractual  arrangements,  including  construction  agreements,  commodity 
contracts, maintenance agreements and other arrangements, may be terminated by the counterparty and/or may allow the 
counterparty to seek liquidated damages.

The situations that could allow a counterparty to terminate the contract and/or seek liquidated damages include:

• 

• 

• 

• 

• 

• 

• 

the cessation or abandonment of the development, construction, maintenance or operation of a power plant;

failure of a power plant to achieve construction milestones or commercial operation by agreed-upon deadlines;

failure of a power plant to achieve certain output or efficiency minimums;

our failure to make any of the payments owed to the counterparty or to establish, maintain, restore, extend the term 
of or increase any required collateral;

failure of a power plant to obtain material permits and regulatory approvals by agreed-upon deadlines;

a material breach of a representation or warranty or our failure to observe, comply with or perform any other material 
obligation under the contract; or

events of liquidation, dissolution, insolvency or bankruptcy.

Revenue may be reduced significantly upon expiration or termination of our PPAs.

Some of the capacity from our existing portfolio is sold under long-term PPAs that expire at various times. We seek to 
sell any capacity not sold under long-term PPAs, on a short-term basis as market opportunities arise. Our uncontracted capacity 
is generally sold on the spot market at current market prices as merchant energy. When the terms of each of our various PPAs 
expire, it is possible that the price paid to us for the generation of power under subsequent arrangements or in short term markets 
may be significantly less than the price that had been paid to us under the PPA. Power plants without long-term PPAs involve risk 
and uncertainty in forecasting future demand load for merchant sales because they are exposed to market fluctuations for some 
38

or all of  their generating capacity and  output. A  significant under- or  over-estimation of load requirements may increase our 
operating costs. Without the benefit of long-term PPAs, we may not be able to sell any or all of the capacity from these power 
plants at commercially attractive rates and these power plants may not be able to operate profitably. Certain of our PPAs have 
values in excess of current market prices. We are at risk of loss of margins to the extent that these contracts expire or are terminated 
and we are unable to replace them on comparable terms. Additionally, our PPAs contain termination provisions standard to contracts 
in our industry such as negligence, performance default or prolonged events of force majeure.

An economic downturn could result in a reduction in our revenue and operating cash flows or result in our customers, 

counterparties, vendors or other service providers failing to perform under their contracts with us.

To the extent that an economic downturn returns and affects the markets in which we operate, demand for power and 
power prices may be depressed, and our revenues and operating cash flows could be negatively impacted. In addition, challenges 
affecting the economy could cause our customers, counterparties, vendors and service providers to experience deteriorating credit 
and serious cash flow problems. As a result, these conditions could cause counterparties in the natural gas and power markets, 
particularly in the energy commodity derivative markets that we rely on for our hedging activities, to be unable to perform under 
existing contracts, or to withdraw from participation in those markets. If multiple parties withdraw from those markets, market 
liquidity may be threatened, which in turn could adversely impact our business. Additionally, these conditions may cause our 
counterparties to seek bankruptcy protection under Chapter 11 or liquidation under Chapter 7 of the Bankruptcy Code.

Power Operations

Our power generating operations performance involves significant risks and hazards and may be below expected levels of 

output or efficiency.

The  operation  of  power  plants  involves  risks,  including  the  breakdown  or  failure  of  power  generation  equipment, 
transmission lines, pipelines or other equipment or processes, performance below expected levels of output or efficiency and risks 
related to the creditworthiness of our contract counterparties and the creditworthiness of our counterparties’ customers or other 
parties, such as steam hosts, with whom our counterparties have contracted. From time to time our power plants have experienced 
unplanned outages, including extensions of scheduled outages due to equipment breakdowns, failures or other problems and are 
an inherent risk of our business. Unplanned outages typically can result in lost revenues, increase our maintenance expenses and 
may reduce our profitability, which could have a material adverse effect on our financial condition, results of operations and cash 
flows.

In addition, an unplanned outage may prevent the affected power plant from performing under any applicable PPAs, 
commodity contracts or other contractual arrangements. Such failure may allow a counterparty to terminate an agreement and/or 
seek liquidated damages, and we could incur costs to cover our hedges. Although insurance is maintained to partially protect 
against operating risks, the proceeds of insurance may not be adequate to cover lost revenues or increased expenses. As a result, 
we could be unable to service principal and interest payments under, or may otherwise breach, our financing obligations, particularly 
with respect to the affected power plant, which could result in losing our interest in the affected power plant or, possibly, one or 
more other power plants.

We may be subject to future claims, litigation and enforcement.

Our power generating operations are inherently hazardous and may lead to catastrophic events, including loss of life, 
personal injury and destruction of property, and subject us to litigation. Natural gas is highly explosive and power generation 
involves hazardous activities, including acquiring, transporting and delivering fuel, operating large pieces of rotating equipment 
and delivering power to transmission and distribution systems. These and other hazards can cause severe damage to and destruction 
of property, plant and equipment and suspension of operations. In the worst circumstances, catastrophic events can cause significant 
personal injury or loss of life. Further, the occurrence of any one of these events may result in us being named as a defendant in 
lawsuits asserting claims for substantial damages. We maintain an amount of insurance protection that we consider adequate; 
however, we cannot provide any assurance that the insurance will be sufficient or effective under all circumstances and against 
all hazards or liabilities to which we are subject.

Additionally, we are party to various litigation matters, including regulatory and administrative proceedings arising out 
of the normal course of business. We review our litigation activities and determine if an unfavorable outcome to us is considered 
“remote,” “reasonably possible” or “probable” as defined by U.S. GAAP. Where we have determined an unfavorable outcome is 
probable and is reasonably estimable, we have accrued for potential litigation losses. A successful claim against us that is not fully 
insured could be material. The liability we may ultimately incur with respect to such litigation matters, in the event of a negative 
outcome, may be in excess of amounts currently accrued, if any. Where we determine an unfavorable outcome is not probable or 
reasonably estimable, we do not accrue for any potential litigation loss. The ultimate outcome of these litigation matters cannot 
39

presently be determined, nor can the liability that could potentially result from a negative outcome be reasonably estimated. As a 
result, we give no assurance that such litigation matters would, individually or in the aggregate, not have a material adverse effect 
on our financial condition, results of operations or cash flows. See also Note 15 of the Notes to Consolidated Financial Statements 
for a description of our more significant litigation matters.

We rely on power transmission and fuel distribution facilities owned and operated by other companies.

We depend on facilities and assets that we do not own or control for the transmission to our customers of the power 
produced by our power plants and the distribution of natural gas fuel or fuel oil to our power plants. If these transmission and 
distribution systems are disrupted or capacity on those systems is inadequate, our ability to sell and deliver power products or 
obtain fuel may be hindered. ISOs that oversee transmission systems in regional power markets have imposed price limitations 
and other mechanisms to address volatility in their power markets. Existing congestion, as well as expansion of transmission 
systems, could affect our performance, which in turn could adversely impact our business.

Our power project development and construction activities involve risk and may not be successful.

The development and construction of power plants is subject to substantial risks. In connection with the development of 

a power plant, we must generally obtain:

• 

• 

• 

• 

• 

necessary power generation equipment;

governmental permits and approvals including environmental permits and approvals;

fuel supply and transportation agreements;

sufficient equity capital and debt financing;

power transmission agreements;

•  water supply and wastewater discharge agreements or permits; and

• 

site agreements and construction contracts.

To the extent that our development and construction activities continue or expand, we may be unsuccessful on a timely 
and profitable basis. Although we may attempt to minimize the financial risks of these activities by securing a favorable PPA and 
arranging adequate financing prior to the commencement of construction, the development of a power project may require us to 
expend significant cash sums for preliminary engineering, permitting, legal and other expenses before we can determine whether 
a project is feasible, economically attractive or financeable. The process for obtaining governmental permits and approvals is 
complicated and lengthy, often taking more than one year, and is subject to significant uncertainties. We may be unable to obtain 
all necessary licenses, permits, approvals and certificates for proposed projects, and completed power plants may not comply with 
all applicable permit conditions, statutes or regulations. In addition, regulatory compliance for the construction and operation of 
our  power  plants  can  be  a  costly  and  time-consuming  process.  Intricate  and  changing  environmental  and  other  regulatory 
requirements may necessitate substantial expenditures to obtain and maintain permits. If a project is unable to function as planned 
due to changing requirements, loss of required permits or regulatory status or local opposition, it may create expensive delays, 
extended periods of non-operation or significant loss of value in a project resulting in potential impairments.

We may be unable to obtain an adequate supply of fuel in the future.

We obtain substantially all of our physical natural gas and fuel oil supply from third parties pursuant to arrangements 
that vary in term, pricing structure, firmness and delivery flexibility. Our physical natural gas and fuel oil supply arrangements 
must be coordinated with transportation agreements, balancing agreements, storage services, financial hedging transactions and 
other contracts so that the natural gas and fuel oil is delivered to our power plants at the times, in the quantities and otherwise in 
a manner that meets the needs of our generation portfolio and our customers. We must also comply with laws and regulations 
governing natural gas transportation.

While adequate supplies of natural gas and fuel oil are currently available to us at prices we believe are reasonable for 
each of our power plants, we are exposed to increases in the price of natural gas and fuel oil, and it is possible that sufficient 
supplies to operate our portfolio profitably may not continue to be available to us. In addition, we face risks with regard to the 
delivery to and the use of natural gas and fuel oil by our power plants including the following:

• 

• 

transportation may be unavailable if pipeline infrastructure is damaged or disabled;

pipeline tariff changes may adversely affect our ability to, or cost to, deliver natural gas and fuel oil supply;

40

• 

third-party suppliers may default on natural gas supply obligations, and we may be unable to replace supplies currently 
under contract;

•  market liquidity for physical natural gas and fuel oil or availability of natural gas and fuel oil services (e.g. storage) 

may be insufficient or available only at prices that are not acceptable to us;

• 

• 

• 

• 

natural gas and fuel oil quality variation may adversely affect our power plant operations;

our natural gas and fuel oil operations capability may be compromised due to various events such as natural disaster, 
loss of key personnel or loss of critical infrastructure; 

fuel supplies diverted to residential heating for humanitarian reasons; and

any other reasons.

Our power plants and construction projects are subject to impairments.

If we were to experience a significant reduction in our expected revenues and operating cash flows for an extended period 
of time from a prolonged economic downturn or from advances or changes in technologies, we could experience future impairments 
of our power plant assets as a result. There can be no assurance that any such losses or impairments to the carrying value of our 
financial assets would not have a material adverse impact our financial condition, results of operations and cash flows.

Our geothermal power reserves may be inadequate for our operations.

In connection with each geothermal power plant, we estimate the productivity of the geothermal resource and the expected 
decline in productivity. The productivity of a geothermal resource may decline more than anticipated, resulting in insufficient 
reserves being available for sustained generation of the power capacity desired. In addition, we may not be able to successfully 
manage the development and operation of our geothermal reservoirs or accurately estimate the quantity or productivity of our 
steam reserves. An incorrect estimate or inability to manage our geothermal reserves or a decline in productivity could adversely 
affect our results of operations or financial condition. In addition, the development and operation of geothermal power resources 
are subject to substantial risks and uncertainties. The successful exploitation of a geothermal power resource ultimately depends 
upon many factors including the following:

• 

• 

• 

• 

• 

• 

the heat content of the extractable steam or fluids;

the geology of the reservoir;

the total amount of recoverable reserves;

operating expenses relating to the extraction of steam or fluids;

price levels relating to the extraction of steam, fluids or power generated; and

capital expenditure requirements relating primarily to the drilling of new wells.

Significant events beyond our control, such as natural disasters or acts of terrorism, could damage our power plants or our 

corporate offices and may impact us in unpredictable ways.

Certain of our geothermal and natural gas-fired power plants, particularly in the West, are subject to frequent low-level 
seismic disturbances. More significant seismic disturbances are possible. In addition, other areas in which we operate, particularly 
in Texas and the Southeast, experience tornados and hurricanes. Similarly, operations at our corporate offices in Houston, Texas 
could be substantially affected by a hurricane. Such events could damage or shut down our power plants, power transmission or 
the fuel supply facilities upon which our generation business is dependent. Our existing power plants are built to withstand relatively 
significant  levels  of  seismic  and  other  disturbances,  and  we  believe  we  maintain  adequate  insurance  protection.  However, 
earthquake, property damage or business interruption insurance may be inadequate to cover all potential losses sustained in the 
event of serious damages or disturbances to our power plants or our operations due to natural disasters.

In addition to physical damage to our power plants, the risk of future terrorist activity could result in adverse changes in 
the insurance markets and disruptions in the power and fuel markets. These events could also adversely affect the U.S. economy, 
create instability in the financial markets and, as a result, have an adverse effect on our ability to access capital on terms and 
conditions acceptable to us.

41

We depend on our management and employees.

Our success is largely dependent on the skills, experience and efforts of our people. The loss of the services of one or 
more members of our senior management or of numerous employees with critical skills could have a negative effect on our business, 
financial condition and results of operations and future growth if we were unable to replace them.

Some of our employees are represented by collective bargaining agreements.

We have 158 employees represented by collective bargaining agreements; however, the amount of employees subject to 
collective bargaining agreements only represents a small percentage (approximately 7%) of our employee base. In the event that 
our union employees participate in a strike, work stoppage or engage in other forms of labor disruption, we would be responsible 
for procuring replacement labor and could experience reduced power generation or outages. 

We depend on computer and telecommunications systems we do not own or control and failures in our systems or cyber 

security attacks could significantly disrupt our business operations.

We have entered into agreements with third parties for hardware, software, telecommunications and other information 
technology services in connection with the operation of our power plants. In addition, we have developed proprietary software 
systems,  management  techniques  and  other  information  technologies  incorporating  software  licensed  from  third  parties.  It  is 
possible we could incur interruptions from cyber security attacks, computer viruses or malware. We believe that we have positive 
relations with our related vendors and maintain adequate anti-virus and malware software and controls; however, any interruptions 
to our arrangements with third parties, to our computing and communications infrastructure, or our information systems could 
significantly disrupt our business operations.

Capital Resources; Liquidity

We have substantial liquidity needs and could face liquidity pressure.

As of December 31, 2012, our consolidated debt outstanding was $10.8 billion, of which approximately $7.8 billion was 
outstanding under our First Lien Notes and First Lien Term Loans. In addition we had $626 million issued in letters of credit and 
our pro rata share of unconsolidated subsidiary debt was approximately $224 million. Although we significantly extended our 
maturities during 2011 and 2010, we could face liquidity challenges as we continue to have substantial debt and substantial liquidity 
needs in the operation of our business. Our ability to make payments on our indebtedness, to meet margin requirements and to 
fund planned capital expenditures and development efforts will depend on our ability to generate cash in the future from our 
operations and our ability to access the capital markets. This, to a certain extent, is dependent upon industry conditions, as well 
as general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control, as discussed 
further in “— Commercial Operations” above. Although we are permitted to enter into new project financing credit facilities to 
fund our development and construction activities, there can be no assurance that we will not face liquidity pressure in the future. 
See additional discussion regarding our capital resources and liquidity in Item 7. “Management’s Discussion and Analysis of 
Financial Condition and Results of Operations — Liquidity and Capital Resources.”

Our substantial indebtedness could adversely impact our financial health and limit our operations.

Our level of indebtedness has important consequences, including:

• 

• 

• 

• 

• 

• 

limiting our ability to borrow additional amounts for working capital, capital expenditures, debt service requirements, 
potential growth or other purposes;

limiting our ability to use operating cash flows in other areas of our business because we must dedicate a substantial 
portion of these funds to service our debt;

increasing our vulnerability to general adverse economic and industry conditions;

limiting our ability to capitalize on business opportunities and to react to competitive pressures and adverse changes 
in governmental regulation;

limiting our ability or increasing the costs to refinance indebtedness or to repurchase equity issued by certain of our 
subsidiaries to third parties; and

limiting  our  ability  to  enter  into  marketing,  hedging  and  optimization  activities  by  reducing  the  number  of 
counterparties with whom we can transact as well as the volume and type of those transactions.

42

The soundness of financial institutions could adversely affect us.

We have exposure to many different financial institutions and counterparties including those under our First Lien Notes, 
First  Lien  Term  Loans,  Corporate  Revolving  Facility  and  other  credit  and  financing  arrangements  as  we  routinely  execute 
transactions  in  connection  with  our  hedging  and  optimization  activities,  including  brokers  and  dealers,  commercial  banks, 
investment banks and other institutions and industry participants. Many of these transactions expose us to credit risk in the event 
that any of our lenders or counterparties are unable to honor their commitments or otherwise defaults under a financing agreement.

We may be unable to obtain additional financing or access the credit and capital markets in the future at prices that are 

beneficial to us or at all.

If our available cash, including future cash flows generated from operations, is not sufficient in the near term to finance 
our operations, post collateral or satisfy our obligations as they become due, we may need to access the capital and credit markets. 
Our ability to arrange financing (including any extension or refinancing) and the cost of the financing is dependent upon numerous 
factors, including general economic and capital market conditions. Market disruptions such as those experienced in the U.S. and 
abroad in recent years, may increase our cost of borrowing or adversely affect our ability to access capital. In addition, we believe 
these conditions have and may continue to have an adverse effect on the price of our common stock, which in turn may also reduce 
our ability to access capital or credit markets. Other factors include:

• 

• 

• 

• 

• 

• 

• 

low credit ratings may prevent us from obtaining any material amount of additional debt financing;

conditions in energy commodity markets;

regulatory developments;

credit availability from banks or other lenders for us and our industry peers;

investor confidence in the industry and in us;

the continued reliable operation of our current power plants; and

provisions of tax, regulatory and securities laws that are conducive to raising capital.

While we have utilized non-recourse or lease financing when appropriate, market conditions and other factors may prevent 
us from completing similar financings in the future. It is possible that we may be unable to obtain the financing required to develop, 
construct, acquire or expand power plants on terms satisfactory to us. We have financed our existing power plants using a variety 
of leveraged financing structures, including senior secured and unsecured indebtedness, construction financing, project financing, 
term loans and lease obligations. In the event of a default under a financing agreement which we do not cure, the lenders or lessors 
would generally have rights to the power plant and any related assets. In the event of foreclosure after a default, we may not be 
able to retain any interest in the power plant or other collateral supporting such financing. In addition, any such default or foreclosure 
may trigger cross default provisions in our other financing agreements. 

Our First Lien Notes, First Lien Term Loans, Corporate Revolving Facility, CCFC Notes and our other debt instruments 
impose restrictions on us and any failure to comply with these restrictions could have a material adverse effect on our liquidity 
and our operations.

The restrictions under our First Lien Notes, First Lien Term Loans, Corporate Revolving Facility, CCFC Notes and other 
debt instruments could adversely affect us by limiting our ability to plan for or react to market conditions or to meet our capital 
needs and, if we were unable to comply with these restrictions, could result in an event of default under these debt instruments. 
These restrictions require us to meet certain financial performance tests on a quarterly basis and limit or prohibit our ability, subject 
to certain exceptions to, among other things:

• 

• 

• 

incur or guarantee additional first lien indebtedness up to certain consolidated net tangible asset ratios;

enter into certain types of commodity hedge agreements that can be secured by first lien collateral;

enter into sale and leaseback transactions;

•  make certain investments;

• 

• 

• 

create or incur liens;

consolidate or merge with or transfer all or substantially all of our assets to another entity, or allow substantially all 
of our subsidiaries to do so;

lease, transfer or sell assets and use proceeds of permitted asset leases, transfers or sales;

43

• 

• 

engage in certain business activities; and

enter into certain transactions with our affiliates.

Our First Lien Notes, First Lien Term Loans, Corporate Revolving Facility, CCFC Notes and our other debt instruments 
contain events of default customary for financings of their type, including a cross default to debt other than non-recourse project 
financing debt, a cross-acceleration to non-recourse project financing debt and certain change of control events. If we fail to comply 
with the covenants and are unable to obtain a waiver or amendment, or a default exists and is continuing under such debt, the 
lenders or the holders or trustee of the First Lien Notes, as applicable, could give notice and declare outstanding borrowings and 
other obligations under such debt immediately due and payable.

Our ability to comply with these covenants may be affected by events beyond our control, and any material deviations 
from our forecasts could require us to seek waivers or amendments of covenants or alternative sources of financing or to reduce 
expenditures. We may not be able to obtain such waivers, amendments or alternative financing, or if obtainable, it could be on 
terms that are not acceptable to us. If we are unable to comply with the terms of our First Lien Notes, First Lien Term Loans, 
Corporate Revolving Facility, CCFC Notes and our other debt instruments, or if we fail to generate sufficient cash flows from 
operations, or if it becomes necessary to obtain such waivers, amendments or alternative financing, it could adversely impact our 
financial condition, results of operations and cash flows.

Our credit status is below investment grade, which may restrict our operations, increase our liquidity requirements and 

restrict financing opportunities.

Our corporate and debt credit ratings are below investment grade. There is no assurance that our credit ratings will 
improve in the future, which may restrict the financing opportunities available to us or may increase the cost of any available 
financing. Our current credit rating has resulted in the requirement that we provide additional collateral in the form of letters of 
credit or cash for credit support obligations and may adversely impact our subsidiaries’ and our financial position and results of 
operations.

Certain of our obligations are required to be secured by letters of credit or cash, which increase our costs; if we are unable 

to provide such security it may restrict our ability to conduct our business.

Companies  using  derivatives,  which  include  many  commodity  contracts,  are  subject  to  the  inherent  risks  of  such 
transactions. Consequently, many such companies, including us, may be required to post cash collateral for certain commodity 
transactions; and,  the level of  collateral will  increase as  a  company increases  its hedging  activities. We use  margin  deposits, 
prepayments  and  letters  of  credit  as  credit  support  for  commodity  procurement  and  risk  management  activities.  Future  cash 
collateral requirements may increase based on the extent of our involvement in standard contracts and movements in commodity 
prices, and also based on our credit ratings and general perception of creditworthiness in this market. Certain of our financing 
arrangements for our power plants have required us to post letters of credit which are at risk of being drawn down in the event 
we, or the applicable subsidiary, default on our obligations.

Many of our collateral agreements require that letters of credit posted as collateral must be issued by a financial institution 
with a minimum credit rating of “A”. Currently the financial institutions that issue letters of credit under our Corporate Revolving 
Facility and other letter of credit facilities meet or exceed the minimum credit rating criteria. However, if one or more of these 
financial institutions is no longer able to meet the minimum credit rating criteria, then we could be required to post collateral 
funding from our cash and cash equivalents which could negatively impact our liquidity.

Additionally, changes in market regulations can increase the use of credit support and collateral. The potential impact of 
the Dodd-Frank Act is uncertain, but it is possible that future regulations, when finalized, under the Dodd-Frank Act could directly 
or indirectly result in increased credit support and collateral requirements.

These letter of credit and cash collateral requirements increase our cost of doing business and could have an adverse 
impact on our overall liquidity, particularly if there was a call for a large amount of additional cash or letter of credit collateral 
due to an unexpectedly large movement in the market price of a commodity. As of December 31, 2012, we had $626 million issued 
in letters of credit under our Corporate Revolving Facility and other facilities, with $757 million remaining available for borrowing 
or for letter of credit support under our Corporate Revolving Facility. In addition, we have ratably secured our obligations under 
certain of our power and natural gas agreements that qualify as eligible commodity hedge agreements under our Corporate Revolving 
Facility with the assets previously subject to liens under our First Lien Credit Facility.

44

We may not have sufficient liquidity to hedge market risks effectively.

We are exposed to market risks through our sale of power, capacity and related products and the purchase and sale of 
fuel, transmission services and emission allowances. These market risks include, among other risks, volatility arising from location 
and timing differences that may be associated with buying and transporting fuel, converting fuel into power and delivering the 
power to a buyer.

We undertake these activities through agreements with various counterparties, many of which require us to provide 
guarantees, offset or netting arrangements, letters of credit, a second lien on assets and/or cash collateral to protect the counterparties 
against the risk of our default or insolvency. The amount of such credit support that must be provided typically is based on the 
difference between the price of the commodity in a given contract and the market price of the commodity. Significant movements 
in  market  prices  can  result  in  our  being  required  to  provide  cash  collateral  and  letters  of  credit  in  very  large  amounts.  The 
effectiveness of our strategy may be dependent on the amount of collateral available to enter into or maintain these contracts, and 
liquidity requirements may be greater than we anticipate or will be able to meet. Without a sufficient amount of working capital 
to post as collateral in support of performance guarantees or as a cash margin, we may not be able to manage price volatility 
effectively or to implement our strategy. An increase in the amount of letters of credit or cash collateral required to be provided 
to our counterparties may negatively affect our liquidity and financial condition.

Further, if any of our power plants experience unplanned outages, we may be required to procure replacement power at 
spot  market  prices  in  order  to  fulfill  contractual  commitments.  Without  adequate  liquidity  to  meet  margin  and  collateral 
requirements, we may be exposed to significant losses, may miss significant opportunities and may have increased exposure to 
the volatility of spot markets.

Our ability to receive future cash flows generated from the operation of our subsidiaries may be limited.

Almost all of our operations are conducted through our subsidiaries and other affiliates. As a result, we depend almost 
entirely upon their earnings and cash flows to service our indebtedness, post collateral and finance our ongoing operations. Certain 
of our project debt and other agreements restrict our ability to receive dividends and other distributions from our subsidiaries. 
Some of these limitations are subject to a number of significant exceptions (including exceptions permitting such restrictions in 
connection with certain subsidiary financings). Accordingly, the financing agreements of certain of our subsidiaries and other 
affiliates generally restrict their ability to pay dividends, make distributions or otherwise transfer funds to us prior to the payment 
of their other obligations, including their outstanding debt, operating expenses, lease payments and reserves or during the existence 
of a default.

We may utilize project financing, preferred equity and other types of subsidiary financing transactions when appropriate 
in the future, which could increase our debt and may be structurally senior to other debt such as our First Lien Notes, First 
Lien Term Loans and Corporate Revolving Facility.

Our ability and the ability of our subsidiaries to incur additional indebtedness are limited in some cases by existing 
indentures,  debt  instruments  or  other  agreements.  Our  subsidiaries  may  incur  additional  construction/project  financing 
indebtedness, issue preferred equity to finance the acquisition and development of new power plants and engage in certain types 
of non-recourse financings to the extent permitted by existing agreements, and may continue to do so in order to fund our ongoing 
operations. Any such newly incurred subsidiary preferred equity would be added to our current consolidated debt levels and would 
likely be structurally senior to our debt, which could also intensify the risks associated with our already existing leverage.

Our First Lien Notes, First Lien Term Loans and Corporate Revolving Facility are effectively subordinated to certain project 

indebtedness.

Certain of our subsidiaries and other affiliates are separate and distinct legal entities and, except in limited circumstances, 
have no obligation to pay any amounts due with respect to our indebtedness or indebtedness of other subsidiaries or affiliates, and 
do not guarantee the payment of interest on or principal of such indebtedness. In the event of our bankruptcy, liquidation or 
reorganization (or the bankruptcy, liquidation or reorganization of a subsidiary or affiliate), such subsidiaries’ or other affiliates’ 
creditors, including trade creditors and holders of debt issued by such subsidiaries or affiliates, will generally be entitled to payment 
of their claims from the assets of those subsidiaries or affiliates before any assets are made available for distribution to us or the 
holders of our indebtedness. As a result, holders of our indebtedness will be effectively subordinated to all present and future debts 
and  other  liabilities  (including  trade  payables)  of  certain  of  our  subsidiaries. As  of  December 31,  2012,  our  subsidiaries  had 
approximately $1.0 billion in debt from our CCFC subsidiary and approximately $1.8 billion in secured project financing from 
other subsidiaries, which are effectively senior to our First Lien Notes, First Lien Term Loans and Corporate Revolving Facility. 
We may incur additional project financing indebtedness in the future, which will be effectively senior to our other secured and 
unsecured debt.

45

Governmental Regulation

Existing and proposed federal and state RPS and energy efficiency, as well as economic support for renewable sources of 

power under the U.S economic stimulus legislation could adversely impact our operations.

Federal policymakers have been considering imposing a national RPS on retail power providers. California already has 
an RPS in effect and in 2011 signed into law legislation requiring implementation of a 33% RPS by 2020. A number of additional 
states, including Maine, Minnesota, New York, Texas and Wisconsin, have an array of different RPS in place. Existing state-
specific RPS requirements may change due to regulatory and/or legislative initiatives, and other states may consider implementing 
enforceable RPS in the future. A national RPS or more robust RPS in states in which we are active, coupled with economic 
incentives provided under the federal stimulus package, would likely initially drive up the number of wind and solar resources, 
increasing power supply to various markets which could negatively impact the dispatch of our natural gas-fired power plants, 
primarily in Texas and California.

Similarly, federal legislators are considering national energy efficiency initiatives. Several states already have energy 
efficiency initiatives in place while others are considering imposing them. Improved energy efficiency when mandated by law or 
promoted by government sponsored incentives can decrease demand for power which could negatively impact the dispatch of our 
natural gas-fired power plants, primarily in Texas and California.

State legislative and regulatory action, such as the actions taken in New Jersey and Maryland to impermissibly increase 

power plant construction in those states, could adversely impact our competitive position and business.

Certain states in the PJM market region, particularly New Jersey and Maryland, have taken actions that could impact the 
PJM capacity market. In New Jersey, legislation enacted in 2011 required the New Jersey Board of Public Utilities (“BPU”) to 
issue a request for proposals (“RFP”) for new generation. As a result of the RFP, the BPU directed New Jersey’s four public utilities 
to enter into standard offer capacity agreements with the winning generators for new capacity to be built in New Jersey. Several 
entities have appealed the BPU’s order directing the public utilities to enter into long-term contracts with those generators. The 
appeal process continues. Also, on February 9, 2011, we joined a group of generators and utilities in filing a complaint in federal 
district court challenging the constitutionality of the New Jersey legislation. On September 28, 2012, the judge in the proceeding 
denied all Motions for Summary Judgment. Discovery is continuing with a trial expected to be held in late March to early April 
2013.

On September 29, 2011, the Maryland Public Service Commission (“MPSC”) issued a “Notice of Approval of Request 
for Proposals for New Generation to be Issued by Maryland Electric Distribution Companies” (the “Notice”). The Notice required 
the state’s IOUs to issue RFPs for up to 1,500 MW of capacity. The Notice specifies that proposals must be for new natural gas-
fired capacity capable of delivery into the PJM Southwest Mid-Atlantic Area Council (“SWMAAC”) delivery area. On April 12, 
2012, the MPSC issued a further order in this proceeding directing certain Maryland IOUs located in the SWMAAC area to enter 
into a contract for differences with CPV Maryland, LLC (“CPV”), a generation developer that is currently developing a 661 MW 
natural gas-fired, combined-cycle generation plant in SWMAAC. The facility’s scheduled COD is June 1, 2015. In May 2012, 
we filed with the Circuit Court of Baltimore County, Maryland a Petition for Review of the MPSC’s order, asking the court to 
review the order and declare it invalid. Several other parties filed similar appeals. The appeals have been consolidated, but the 
case has been suspended pending resolution of certain terms in the contracts between the IOUs and CPV. In a separate action, 
several generators have filed a complaint in federal district court challenging the constitutionality of the MPSC’s actions. That 
case is expected to go to trial in late February 2013.

At the FERC level, PJM has taken action to strengthen the Minimum Offer Price Rule (“MOPR”) in its tariff. PJM’s 
tariff changes are intended to address the negative implications from these state actions. The FERC issued an order in April 2011 
approving amendments to PJM’s MOPR tariff provisions. The FERC order is currently on appeal before the U.S. Court of Appeals 
for the Third Circuit. In December 2012, PJM filed further amendments to the MOPR that are intended to make the MOPR process 
more transparent and objective. On February 5, 2013, the FERC asked PJM to provide additional information about its proposal. 
While unclear, given the current timing of PJM’s response and a subsequent FERC decision, it is still possible for the changes to 
be in effect for the 2016/2017 PJM Reliability Pricing Model base residual auction, to be held on May 13-17, 2013.

Unless these anticompetitive actions in New Jersey and Maryland are overturned by the courts or mitigated by the FERC, 
they could have an adverse impact on the deregulated PJM electricity markets by discouraging the construction of new generation 
which in turn could have a negative impact on our business prospects and financial results.

Increased oversight and investigation by the CFTC relating to derivative transactions, as well as certain financial institutions, 

could have an adverse impact on our ability to hedge risks associated with our business.

The CFTC has regulatory oversight of the futures markets, including trading on NYMEX for energy, and licensed futures 
professionals such as brokers, clearing members and large traders. In connection with its oversight of the futures markets and 
NYMEX, the CFTC regularly investigates market irregularities and potential manipulation of those markets. Recent laws also 
give the CFTC certain powers with respect to broker-type markets referred to as “exempt commercial markets” or ECMs, including 
the Intercontinental Exchange. The CFTC monitors activities in the OTC, ECM and physical markets that may be undertaken for 
the purpose of influencing futures prices. With respect to ECMs, the CFTC exercises only light-handed regulation primarily related 
to  trade  reporting,  price  dissemination  and  record  retention  (including  retention  of  fraudulent  claims  and  allegations). Thus, 
transactions executed on an ECM generally are not regulated directly by the CFTC. However, the CFTC may make special calls 
of market participants in the ECM and ECM transactions have come under the CFTC’s scrutiny during investigations of fraud 
and  manipulation  in  which  the  CFTC  has  broadly  applied  its  statutory  authority  to  punish  persons  who  are  alleged  to  have 
manipulated, or attempted to manipulate, the price of any commodity in interstate commerce or for future delivery. Moreover, 
while ECM transactions are not required to be cleared, if they are cleared, such cleared ECM transaction would be subject to 
regulation by the CFTC. We also expect the CFTC’s powers and oversight to be increased by the Dodd-Frank Act. However, as 
discussed below, the extent of such increased powers and oversight, and its effect on ECM transactions, if any, is not yet certain.

The unknown impact from the Dodd-Frank Act as well as the rules to be promulgated under it could have an adverse impact 
on our ability to hedge risks associated with our business, require the implementation of additional policies and require us to 
incur administrative compliance costs.

The  Dodd-Frank Act  contains  a  variety  of  provisions  designed  to  regulate  financial  markets,  including  credit  and 
derivatives transactions. Title VII of the Dodd-Frank Act addresses regulatory reform of the OTC derivatives market in the U.S. 
and  significantly  changes  the  regulatory  framework  of  this  market.  Certain Title VII  regulations  have  been  finalized  and  are 
effective though some regulations remain subject to a delayed compliance schedule. Other key regulations have not been finalized 
as of this time or remain in draft form. Until all of these regulations have been finalized, the extent to which the provisions of Title 
VII might affect our derivatives activities cannot be completely known. A number of features in the legislation may impact our 
existing  business.  One  of  these  is  the  requirement  for  central  clearing  of  many  OTC  derivative  transactions  with  clearing 
organizations. Moreover, whereas our OTC transactions have traditionally been negotiated on a bilateral basis, including the 
collateral arrangements thereunder, they now may be subject to the collateral and margining procedures of the clearing organization. 
Certain end-users may be able to benefit from an exception which would exempt them from mandatory clearing requirements. If 
the derivatives transactions which we enter into are determined to be subject to mandatory clearing requirements, we will seek to 
comply with the regulatory requirements in order to benefit from the end-user exception. Uncleared OTC derivatives transactions 
under the Dodd-Frank Act will also be subject to collateral and margining procedures established by CFTC regulation. These Title 
VII regulations have not, as of the date of this Report, been finalized. Other features of the Dodd-Frank Act which will have an 
impact on our derivative activities include trade reporting and trade execution. The effect of the Dodd-Frank Act on traditional 
dealers and market-makers as well as the consequential effect on market liquidity and, hence, pricing is uncertain. Nevertheless, 
we expect to be able to continue to participate in financial markets for our derivative transactions.

Some of the key regulatory rulemakings regarding the definition of specific entity designations and the swap definition 
rules for the Dodd-Frank Act, which was signed into law on July 21, 2010, were finalized in the second and third quarters of 2012. 
The CFTC also recently issued several no-action letters, interpretations and an exemptive order impacting the implementation 
schedule  and  interpretations  of  key  provisions  in  the  CFTC’s  Dodd-Frank Act  implementation  rules. We  have  reviewed  our 
derivative activities over a one month survey period, as a proxy for future activity, and our intended future activities, and have 
determined that we are not a swap dealer as defined under the CFTC’s final entity definition rule and, therefore, are not required 
to register as a swap dealer. We have established an internal working group for a thorough and ongoing evaluation of the impact 
and timing of these recent rulemakings on our operations as a non-swap dealer; however, it is difficult to fully assess the ultimate 
impact of the Dodd-Frank Act on us until all rulemakings are finalized and implemented.

While we are closely monitoring this rulemaking process from the CFTC (including related no-action relief, interpretations 
and orders), we have reviewed and assessed the impact of the CFTC’s Title VII regulations on our business and related processes, 
and we have adjusted our internal procedures where necessary to comply with the applicable statutory law and related Title VII 
regulations which are effective at this time. We will continue to monitor all relevant developments and rulemaking initiatives, and 
we expect to successfully implement any new applicable requirements. At this time, we cannot predict the impact or possible 
additional costs to us related to the implementation of, or compliance with, the potential future requirements under the Dodd-
Frank Act.

The Dodd-Frank Act contains provisions to improve transparency and accountability concerning the supply of certain 
minerals, known as conflict minerals (namely tin, tantalum, tungsten or gold), originating from the conflict zones of the Democratic 
Republic of Congo (“DRC”) and adjoining countries. In August 2012, as mandated by the Dodd-Frank Act, the SEC adopted final 
rules requiring all issuers that file reports with the SEC to report, on an annual basis, supply chain and sourcing information for 
companies that use conflict minerals mined from the DRC and adjoining countries in their products. These new requirements will 
require due diligence efforts in fiscal 2013, with initial disclosure requirements beginning in May 2014. Based on our preliminary 
analysis, we do not believe that any of our products contain conflict minerals; however, our assessment process to determine 
whether conflict minerals are necessary to the functionality or production of any of our products is not complete. Should we 
conclude that we are subject to the conflict minerals reporting requirements, we will have to determine the most efficient means 
of complying with the disclosure requirements, including diligence procedures to determine the sources of conflict minerals that 
are necessary to the functionality or  production of our products and, if applicable, potential changes to products, processes or 
sources of supply as a consequence of such verification activities. It is also possible that we may face reputational harm if we 
determine that certain of our products contain minerals not determined to be “conflict free” and/or we are unable to alter our 
products, processes or sources of supply to avoid such materials.

Changes in the regulation of the power markets in which we operate could negatively impact us.

We have a significant presence in the major competitive power markets for California, Texas and the Mid-Atlantic region 
of the U.S. While these markets are largely de-regulated, they continue to evolve. Existing regulations within the markets in which 
we operate may be revised or reinterpreted and new laws or regulations may be issued. We cannot predict the future development 
of regulation or legislation nor the ultimate effect such changes in these markets could have on our business; however, we could 
be negatively impacted.

Existing and future anticipated GHG/Carbon and other air emissions regulations could cause us to incur significant costs 

and adversely affect our operations generally or in a particular quarter when such costs are incurred.

Environmental laws and regulations have generally become more stringent over time, and this trend is likely to continue. 
In particular, there is growing likelihood that carbon tax or limits on carbon, CO2 and other GHG emissions will be implemented 
at the federal or expanded at the state or regional levels.

In 2009, ten states in the northeast began the compliance period of a Cap-and-trade program, RGGI, to regulate CO2 
emissions from power plants. California has implemented AB 32 which places a statewide cap on GHG emissions and requires 
the state to return to 1990 emission levels by 2020. In December 2010, CARB adopted a regulation establishing a GHG Cap-and 
trade program which is in effect for electric utilities and other “major industrial sources,” and in 2015 for certain other GHG 
sources.

In 2011, the EPA finalized regulations governing GHG emissions from major sources as well as emissions of criteria and 
hazardous air pollutants from the electric generation sector. We continue to monitor and actively participate in the EPA initiatives 
where we anticipate a material impact on our business.

Further, air regulations enacted in New Jersey that further limit NOX emissions from turbines and boilers beginning in 
2015 will impact six of our power plants that will either need to retire or install additional NOX controls to continue operating 
beyond 2015. We plan to install emissions controls equipment at two of these power plants and have provided notice to PJM of 
our intent to retire the four remaining power plants before the commencement of the PJM Reliability Pricing Model 2015/2016 
delivery year. We do not expect the retirement of these power plants or installation of emissions controls to have a material impact 
on our financial condition, results of operations or cash flows.

We are subject to other complex governmental regulation which could adversely affect our operations.

Generally, in the U.S., we are subject to regulation by FERC regarding the terms and conditions of wholesale service 
and the sale and transportation of natural gas, as well as by state agencies regarding physical aspects of the power plants. The 
majority of our generation is sold at market prices under the market-based rate authority granted by the FERC. If certain conditions 
are not met, FERC has the authority to withhold or rescind market-based rate authority and require sales to be made based on cost-
of-service rates. A loss of our market-based rate authority could have a materially negative impact on our generation business. 
FERC could also impose fines or other restrictions or requirements on us under certain circumstances.

The construction and operation of power plants require numerous permits, approvals and certificates from the appropriate 
foreign, federal, state and local governmental agencies, as well as compliance with numerous environmental laws and regulations 
of federal, state and local authorities. Should we fail to comply with any environmental requirements that apply to power plant 

48

construction or operations, we could be subject to administrative, civil and/or criminal liability and fines, and regulatory agencies 
could take other actions to curtail our operations.

Furthermore, certain environmental laws impose strict, joint and several liability for costs required to clean up and restore 
sites where hazardous substances have been disposed or otherwise released. We are generally responsible for all liabilities associated 
with the environmental condition of our power plants, including any soil or groundwater contamination that may be present, 
regardless of when the liabilities arose and whether the liabilities are known or unknown, or arose from the activities of predecessors 
or third parties.

If we were deemed to have market power in certain markets as a result of the ownership of our stock by certain significant 
shareholders, we could lose FERC authorization to sell power at wholesale at market-based rates in such markets or be required 
to engage in mitigation in those markets.

Certain of our significant shareholder groups own power generating assets, or own significant equity interests in entities 
with power generating assets, in markets where we currently own power plants. We could be determined to have market power if 
these existing significant shareholders acquire additional significant ownership or equity interest in other entities with power 
generating assets in the same markets where we generate and sell power.

If FERC makes the determination that we have market power, FERC could, among other things, revoke market-based 
rate authority for the affected market-based companies or order them to mitigate that market power. If market-based rate authority 
was revoked for any of our market-based rate companies, those companies would be required to make wholesale sales of power 
based on cost-of-service rates, which could negatively impact their revenues. If we are required to mitigate market power, we 
could be required to sell certain power plants in regions where we are determined to have market power. A loss of our market-
based rate authority or required sales of power plants, particularly if it affected several of our power plants or was in a significant 
market, could have a material negative impact on our financial condition, results of operations and cash flows.

Risks Relating to Our Common Stock

Our principal shareholders own a significant amount of our common stock, giving them influence over corporate transactions 

and other matters.

As of December 31, 2012, four current holders (or related groups of holders) of our common stock have made filings 
with the SEC reporting beneficial ownership, directly or indirectly, individually or as members of a group, of 5% or more of the 
shares of our common stock. These shareholders, who together beneficially owned approximately 40% of our common stock at 
December 31, 2012, may be able to exercise substantial influence over all matters requiring shareholder approval, including the 
election of directors and approval of significant corporate action, such as mergers and other business combination transactions. If 
two or more of these shareholders (or groups of shareholders) vote their shares in the same manner, their combined stock ownership 
may effectively give significant influence over the election of our entire Board of Directors and significant influence over our 
management, operations and affairs. Currently, one member of our Board of Directors, the Chairman of our Board, is affiliated, 
directly or indirectly, with SPO Advisory Corp., one of these shareholders.

Circumstances may occur in which the interests of these shareholders could be in conflict with the interests of other 
shareholders. This concentration of ownership may also have the effect of delaying or preventing a change in control over us 
unless it is supported by these shareholders. Accordingly, the ability of our other shareholders to influence us through voting of 
their shares may be limited or the market price of our common stock may be adversely affected. Additionally, we have filed a 
registration statement on Form S-3 registering the resale of the common stock held by certain members of one of the three groups 
of these shareholders, which permits them to sell a large portion of their shares of common stock without being subject to the 
“trickle out” or other restrictions of Rule 144 under the Securities Act. Sales by any of the four shareholders of all or a substantial 
portion of their shares within a short period of time, could adversely affect the market price of our common stock or could further 
concentrate holdings of our common stock in the remaining three shareholders who hold more than 5% of our common stock.

Transfers of our equity, or issuances of equity, may impair our ability to utilize our federal income tax NOL carryforwards 

in the future.

Under federal income tax law, our NOL carryforwards can be utilized to reduce future taxable income subject to certain 
limitations, including if we were to undergo an ownership change as defined by Section 382 of the IRC. We experienced an 
ownership change on the Effective Date as a result of the cancellation of our old common stock and the distribution of our new 
common stock pursuant to our Plan of Reorganization. However, this ownership change and resulting annual limitations are not 
expected to result in the expiration of our NOL carryforwards if we are able to generate sufficient future taxable income within 
the carryforward periods. If a subsequent ownership change were to occur as a result of future transactions in our stock, accompanied 

49

by a significant reduction in our market value immediately prior to the ownership change, our ability to utilize the NOL carryforwards 
may be significantly limited.

Forward-Looking Information

This  Management’s  Discussion  and Analysis  of  Financial  Condition  and  Results  of  Operations  should  be  read  in 
conjunction with our accompanying Consolidated Financial Statements and related notes. See the cautionary statement regarding 
forward-looking statements on page 1 of this Report for a description of important factors that could cause actual results to differ 
from expected results. See also Item 1A. “Risk Factors.”

INTRODUCTION AND OVERVIEW

Our Business

We are one of the largest power generators in the U.S. measured by power produced. We own and operate primarily 
natural gas-fired and geothermal power plants in North America and have a significant presence in major competitive wholesale 
power markets in California, Texas and the Mid-Atlantic region of the U.S. We sell wholesale power, steam, capacity, renewable 
energy credits and ancillary services to our customers, which include utilities, independent electric system operators, industrial 
and agricultural companies, retail power providers, municipalities, power marketers and others. We have invested in clean power 
generation to become a recognized leader in developing, constructing, owning and operating an environmentally responsible 
portfolio  of  power  plants.  We  purchase  natural  gas  and  fuel  oil  as  fuel  for  our  power  plants,  engage  in  related  natural  gas 
transportation and storage transactions, and we purchase electric transmission rights to deliver power to our customers. We also 
enter into natural gas and power physical and financial contracts to hedge certain business risks and optimize our portfolio of 
power plants. Our goal is to be recognized as the premier wholesale power company in the U.S. as measured by our employees, 
customers, regulators, shareholders and communities in which our facilities are located. We seek to achieve sustainable growth 
through financially disciplined power plant development, construction, acquisition, operation and ownership. We will continue to 
pursue opportunities to improve our fleet performance and reduce operating costs. In order to manage our various physical assets 
and contractual obligations, we will continue to execute commodity agreements within the guidelines of our Risk Management 
Policy. 

We assess our business on a regional basis due to the impact on our financial performance of the differing characteristics 
of these regions, particularly with respect to competition, regulation and other factors impacting supply and demand. Our reportable 
segments are West (including geothermal), Texas, North (including Canada) and Southeast. 

Our portfolio, including partnership interests, consists of 92 power plants, including 4 under construction (1 new power 
plant and 3 expansions of existing power plants),  located throughout 20 states in the U.S. and in Canada, with an aggregate 
generation capacity of 27,321 MW and 1,163 MW under construction. Our fleet, including projects under construction, consists 
of 74 combustion turbine-based plants, 2 fossil steam-based plants, 15 geothermal turbine-based plants and 1 photovoltaic solar 
plant. Our segments have an aggregate generation capacity of 6,751 MW with an additional 773 MW under construction in the 
West, 8,014 MW with additional 390 MW under construction in Texas, 7,320 MW in the North and 5,236 MW in the Southeast. 
Our Geysers Assets are included in our West segment.

Current Year Operational Developments

Our objective is to be the “best-in-class” in regards to certain operational performance metrics, such as safety, availability, 
reliability, efficiency and cost management. In addition, we continue to grow our presence in core markets with an emphasis on 
expansions or modernizations of existing power plants. Our notable operational performance metrics, significant projects under 
construction, organic growth initiatives and modernizations are discussed below:

•  We produced approximately 116 billion KWh of electricity in 2012, 23% more than the same period in 2011 (includes 
generation from power plants owned but not operated by us and our share of generation from our unconsolidated 
power plants).

•  Our entire fleet achieved a forced outage factor of 1.6% in 2012, our lowest on record and an improvement of 36% 

from 2011.

•  Our entire fleet achieved an impressive starting reliability of 98.3% in 2012.

•  During 2012, our outage services subsidiary completed 11 major inspections and 19 hot gas path inspections.

•  For the past twelve consecutive years, our Geysers Assets have reliably generated approximately 6 million MWh per 

year and, in 2012, achieved an exceptional availability factor of approximately 97%.

54

•  Construction of our Russell City Energy Center and modernization at our Los Esteros Critical Energy Facility continue 

to move forward with expected completion dates during the summer of 2013. 

•  We continue to make progress with our turbine modernization program and have ongoing development and expansion 
activities which include the advanced development of the Garrison Energy Center located in Dover, Delaware and 
the expansions of our Deer Park and Channel Energy Centers in Texas which are now under construction.

Enhancing Shareholder Value

We continue to make significant progress to deliver financially disciplined growth, to enhance shareholder value through 
our capital allocation and share repurchases and to set the foundation for continued growth and success. Given our strong cash 
flow from operations, we are committed to remaining financially disciplined in our capital allocation decisions. The year ended 
December 31, 2012 was marked by the following accomplishments:

•  As of the filing of this Report, we have completed our previously announced $600 million share repurchase program, 
having repurchased a total of 35,568,833 shares of our outstanding common stock at an average price paid of $16.87 
per share. In February 2013, our Board of Directors authorized the repurchase of an additional $400 million in shares 
of our common stock, bringing the cumulative authorization total to $1.0 billion.

•  During the first quarter of 2012, we terminated our legacy interest rate swaps formerly hedging our First Lien Credit 
Facility for a payment of approximately $156 million which eliminated our exposure from these instruments to 
further declines in interest rates.

•  On October 9, 2012, we issued our 2019 First Lien Term Loan and used the proceeds to reduce our overall cost of 
debt and simplify our capital structure by redeeming a portion of our First Lien Notes and repaying project debt.

•  On November 7, 2012, we completed the purchase of a modern, natural gas-fired, combined-cycle power plant with 
a nameplate capacity of 800 MW located in Bosque County, Texas for approximately $432 million which increased 
capacity in our Texas segment.

•  On December 27, 2012, we, through our indirect, wholly-owned subsidiary Calpine Power Company, completed the 
sale of 100% of our ownership interest in each of the Broad River Entities for approximately $423 million. This 
transaction resulted in the disposition of our Broad River power plant, an 847 MW natural gas-fired, peaking power 
plant located in Gaffney, South Carolina, and includes a five year consulting agreement with the buyer. We expect 
to use the sale proceeds for our capital allocation activities and for general corporate purposes.

•  On December 31, 2012, we completed the sale of Riverside Energy Center, LLC to WP&L for approximately $402 
million. We expect to use the sale proceeds for our capital allocation activities and for general corporate purposes.

For a further discussion of our capital management and significant financing transactions completed in 2012, see “— 

Liquidity and Capital Resources.”

Customer-Oriented Origination Business

We continue to focus on providing products and services that are beneficial to our customers. A summary of certain 

significant contracts entered into in 2012 is as follows:

•  We entered into a new twenty-year PPA with Western Farmers Electric Cooperative to provide 160 MW of power 
generated by our Oneta Energy Center, commencing in June 2014. The capacity under contract will increase in 
increments, up to a maximum of 280 MW in years 2019 through 2035.

•  We entered into a new five-year PPA with Southwestern Public Service Company, a subsidiary of Xcel Energy, to 
provide an additional 200 MW of power generated by our Oneta Energy Center commencing on June 1, 2014.

•  We entered into a new five-year resource adequacy contract with PG&E for approximately 280 MW of combined 

heat and power capacity from our Los Medanos Energy Center commencing in the summer 2013.

•  We entered into a new seven-year resource adequacy contract with Southern California Edison Company (“SCE”) 
for approximately 280 MW of combined heat and power capacity from our Los Medanos Energy Center and a new 
five-year resource adequacy contract with SCE for approximately 120 MW of combined heat and power capacity 
from our Gilroy Cogeneration Plant, both commencing in January 2014.

•  We amended an existing PPA with Dow Chemical Company for an incremental energy sale of up to approximately 

158,000 MWh per year of energy from our Los Medanos Energy Center which runs through February 2025.

•  We entered into a new fifteen-year PPA with American Electric Power Service Corporation, as agent for Public 
Service Company of Oklahoma, to provide 260 MW of energy, capacity and ancillary services from our Oneta Energy 
Center commencing in June 2016.

55

•  We entered into a new ten-year PPA with the Tennessee Valley Authority to provide the full output of power generated 
by our Decatur Energy Center, a natural gas-fired, combined-cycle power plant that can generate up to 795 MW, 
commencing in January 2013.

Our Regulatory and Environmental Profile

We are subject to complex and stringent energy, environmental and other governmental laws and regulations at the federal, 
state and local levels in connection with the development, ownership and operation of our power plants. Federal and state legislative 
and regulatory actions continue to change how our business is regulated. The EPA is moving forward on climate change regulation, 
and has already promulgated regulations related to other air pollutant emissions, and some states and regions in the U.S. have 
implemented or are considering implementing regulations to reduce GHG emissions. We are actively participating in these debates 
at the federal, regional and state levels. For a further discussion of the environmental and other governmental regulations that 
affect us, see “— Governmental and Regulatory Matters” in Item 1. of this Report. Although we cannot predict the ultimate effect 
future climate change regulations or legislation could have on our business, we believe that we will be less adversely impacted 
by potential Cap-and-trade limits, carbon taxes or required environmental upgrades as a result of future potential regulation or 
legislation addressing GHG, other air emissions, as well as water use or emissions, than compared to our competitors who use 
other fossil fuels or steam condensation technologies.

Since our inception in 1984, we have been a leader in environmental stewardship and have invested in clean power 
generation to become a recognized leader in developing, constructing, owning and operating an environmentally responsible 
portfolio of power plants. The combination of our Geysers Assets and our high efficiency portfolio of natural gas-fired power 
plants results in substantially lower emissions of these gases compared to our competitors’ power plants using other fossil fuels, 
such as coal. Consequently, our power generation portfolio has the lowest GHG footprint per MWh of any major wholesale power 
producer in the U.S. In addition, we strive to preserve our nation’s valuable water and land resources. To condense steam, we 
primarily use cooling towers with a closed water cooling system or air cooled condensers. Since our power plants are modern and 
efficient and utilize clean burning natural gas, we do not require large areas of land for our power plants nor do we require large 
specialized landfills for the disposal of coal ash or nuclear plant waste.

Our Market and Our Key Financial Performance Drivers

The market Spark Spread, sales of RECs, revenues from our PPAs and steam sales and the results from our marketing, 
hedging and optimization activities are the primary drivers of our Commodity Margin and contribute significantly to our financial 
results. The market Spark Spread is primarily impacted by fuel prices, weather and reserve margins, which impact our supply and 
demand fundamentals. Those factors, plus the relationship between our operating Heat Rate compared to the Market Heat Rate, 
our power plant operating performance and availability are key to our financial performance.

Fluctuations in natural gas price levels affect our Commodity Margin (depending on our hedge levels and holding other 
factors constant). When less efficient, higher cost natural gas-fired units set power prices in our regional markets, higher natural 
gas prices tend to increase our Commodity Margin. In these instances, while our production costs increase when natural gas prices 
are higher, our competitors’ costs (and power prices) increase at a greater rate, leading to higher Commodity Margin. Similarly, 
when natural gas prices decline, our Commodity Margin tends to decline.

In 2012, given very low natural gas prices, natural gas-fired, combined-cycle units in many markets were frequently 
cheaper to dispatch than coal-fired power plants. When coal-fired electricity production costs exceed natural gas-fired production 
costs, coal-fired units tend to set power prices. In these hours, lower natural gas prices tend to increase our Commodity Margin, 
since our production costs fall while power prices remain constant (depending on our hedge levels and holding other factors 
constant).

Efficient operation of our fleet creates the opportunity to capture Commodity Margin in a cost effective manner. However, 
unplanned outages during periods when Commodity Margin is positive could result in a loss of that opportunity. We generally 
measure our fleet performance based on our availability factors, Heat Rate and plant operating expense. The higher our availability 
factor, the better positioned we are to capture Commodity Margin. The less natural gas we must consume for each MWh of power 
generated, the lower our Heat Rate. The lower our operating Heat Rate compared to the Market Heat Rate, the more favorable the 
impact on our Commodity Margin. Holding all other factors constant, our Commodity Margin increases when we are able to lower 
our operating Heat Rate compared to the Market Heat Rate and conversely decreases when our operating Heat Rate increases 
compared to the Market Heat Rate. See also “— The Market for Power — Our Power Markets and Market Fundamentals” in 
Item 1. of this Report for additional information on how these factors impact our Commodity Margin.

(1)  Represents generation and capacity from power plants that we both consolidate and operate. See “— Description of Our 
Power Plants – Table of Operating Power Plants and Projects Under Construction and Advanced Development” for our 
total equity generation and capacities.

We evaluate our Commodity revenue and Commodity expense on a collective basis because the price of power and 
natural gas tend to move together as the price for power is generally determined by the variable operating cost of the next marginal 
generator to be dispatched to meet demand. The spread between our Commodity revenue and Commodity expense represents a 
significant portion of our Commodity Margin. Our financial performance is correlated to how we maximize our Commodity 
Margin through management of our portfolio of power plants, as well as our hedging and optimization activities. See additional 
segment discussion in “Commodity Margin and Adjusted EBITDA.”

Commodity revenue, net of Commodity expense, increased $69 million for the year ended December 31, 2012, compared 

to the year ended December 31, 2011, primarily due to:

• 

• 

• 

• 
• 

higher contribution from hedges primarily in our Texas segment during the third quarter of 2012 compared to the 
third quarter of 2011;
higher generation in our Texas and North segments due to lower natural gas prices during 2012 compared to 2011 
and higher generation in our West segment due to improved market conditions, less hydroelectric generation and a 
nuclear power plant outage in California during 2012; and
an extreme cold weather event in Texas that occurred on February 2, 2011, and resulted in unplanned outages at 
some of our power plants, negatively impacting our revenue for the year ended December 31, 2011, which did not 
reoccur in 2012; partially offset by
lower regulatory capacity revenue during 2012 compared to 2011; and
the expiration of contracts which decreased revenue during the year ended December 31, 2012 compared to the year 
ended December 31, 2011.

Generation increased 23% primarily due to lower natural gas prices in our Texas segment during certain periods in the 
first  half  of  2012  and  in  our  North  segment  during  certain  periods  throughout  2012  and  improved  market  conditions,  less 
hydroelectric generation and a nuclear power plant outage in our West segment during the year ended December 31, 2012. During 
the year ended December 31, 2012, generation increased as natural gas prices were low enough that during certain periods some 
of our modern, natural gas-fired, combined-cycle power plants in Texas and PJM became less expensive on a marginal basis than 
coal-fired generation resulting in these plants running baseload. The increase in generation also resulted in a 1% decrease in our 
Steam Adjusted Heat Rate for the year ended December 31, 2012, compared to the year ended December 31, 2011, as our power 
plants tend to operate more efficiently under baseload operations. Our average total MW in operation increased by 84 MW primarily 
due to the acquisition of our 762 MW Bosque Energy Center, our 565 MW York Energy Center which achieved COD in March 
2011 and an increase in capacity resulting from our turbine modernization program partially offset by the temporary shut down 
of our Los Esteros Critical Energy Facility associated with the upgrade from simple-cycle to combined-cycle technology.

Unrealized mark-to-market gain/loss from hedging our future generation and fuel needs, for the year ended December 
31, 2012, compared to the year ended December 31, 2011, had an unfavorable variance of $57 million primarily driven by the 
realization of favorable natural gas hedge positions in 2012 previously reported in unrealized mark-to-market gain/loss at December 
31, 2011, partially offset by settlements during 2012 of Heat Rate hedge positions that were unfavorable based on forward curves 
at December 31, 2011.

Despite a 23% increase in generation, our normal, recurring plant operating expense was largely unchanged for the year 
ended December 31, 2012, compared to the year ended December 31, 2011, after accounting for $20 million in reimbursements 
for insurance claims from prior periods that disproportionately reduced our plant operating expense for the year ended December 
31, 2011.

Depreciation and amortization expense increased by $12 million for the year ended December 31, 2012, compared to the 
year ended December 31, 2011, primarily resulting from a decrease of $17 million for the year ended December 31, 2011 related 
to a revision in the expected settlement dates of the asset retirement obligations related to our natural gas-fired and geothermal 
power plants, partially offset by a decrease of $2 million resulting from lower depreciation associated with the sale of Broad River 
in December 2012.

Gain on sale of assets, net consists of a $215 million gain related to the sale of 100% of our ownership interests in each 
of the Broad River Entities, and a $7 million gain related to the sale of our Riverside Energy Center, both of which closed in 
December 2012. See Note 3 of the Notes to Consolidated Financial Statements for further information.

58

 
 
 
Income from unconsolidated investments in power plants increased for the year ended December 31, 2012, compared 
to the year ended December 31, 2011, primarily due to a $3 million favorable change in fair value related to hedging activities 
associated with derivative contracts at Greenfield LP, a $2 million increase in operating income for Whitby due to the expiration 
of an unfavorable natural gas transportation contract in 2011 and a $1 million increase in operating income for Greenfield LP due 
to lower natural gas prices in 2012 compared to 2011.

Interest expense decreased by $24 million for the year ended December 31, 2012, compared to the year ended December 
31, 2011, primarily due to a decrease in our annual effective interest rate on our consolidated debt, excluding the impacts of 
capitalized interest and unrealized gains (losses) on interest rate swaps, to 7.3% for the year ended December 31, 2012, from 7.6% 
for the year ended December 31, 2011. The issuance of our First Lien Term Loans in 2011 and 2012 allowed us to reduce our 
overall cost of debt by replacing a portion of our First Lien Notes and variable rate project debt with corporate level term loans 
carrying a lower variable interest rate. See Note 6 of the Notes to Consolidated Financial Statements for further information 
regarding the issuance of our First Lien Term Loans, the repayment of the portion of our First Lien Notes and the repayment of 
variable rate project debt.

Loss on interest rate derivatives had a favorable change of $131 million for the year ended December 31, 2012, compared 
to the year ended December 31, 2011, primarily resulting from $91 million of historical unrealized losses previously deferred in 
AOCI and reclassified into income in January 2011 in connection with the retirement of the First Lien Credit Facility term loans. 
Also contributing to the year-over-year change was a favorable change of $40 million resulting from interest rate swap breakage 
costs related to the repayment of project debt in June 2011 and changes in fair value and settlements subsequent to the reclassification 
date of the interest rate swaps formerly hedging our First Lien Credit Facility term loans. See Note 8 of the Notes to Consolidated 
Financial Statements for further discussion of our interest rate swaps formerly hedging our First Lien Credit Facility term loans.

Debt extinguishment costs for the year ended December 31, 2012, consisted of $18 million associated with the redemption 
premium, the write-off of unamortized deferred financing costs and debt premium and discount related to repayment of a portion 
of our First Lien Notes and variable rate project debt during the fourth quarter of 2012, and $12 million associated with the purchase 
of two of the three third party interests in GEC Holdings, LLC in March 2012 that were previously recorded as preferred interests 
and classified as debt under U.S. GAAP. Debt extinguishment costs for the year ended December 31, 2011, primarily consisted 
of $74 million associated with the repayment of the NDH Project Debt in March 2011, $19 million associated with the retirement 
of the First Lien Credit Facility term loans in January 2011 in connection with the issuance of the 2023 First Lien Notes and $5 
million related to the write-off of unamortized deferred financing costs related to the repayment of project debt in June 2011. 

During the year ended December 31, 2012, we recorded an income tax expense of $19 million compared to an income 
tax benefit of $22 million for the year ended December 31, 2011. The unfavorable year-over-year change primarily resulted from 
a one-time $76 million benefit to reduce our valuation allowance due to the election to consolidate the CCFC group with the 
Calpine group for 2011 federal income tax reporting purposes. Also, contributing to the unfavorable year-over-year change was 
a decrease of $14 million in income tax expense for 2011 due to the expiration of a statute of limitation related to an uncertain tax 
position. The overall unfavorable year-over-year change in income tax expense was partially offset by a refund of approximately 
$10 million received in October 2012 related to the IRS approval of our 2004 amended federal income tax return and a decrease 
in income tax expense for 2012 of $39 million primarily related to the application of intraperiod tax allocation and a decrease in 
various state and foreign jurisdiction income taxes for the year ended December 31, 2012, compared to the year ended December 
31, 2011.

Commodity revenue, net of Commodity expense, increased $63 million for the year ended December 31, 2011, compared 

to the year ended December 31, 2010, primarily due to:

• 

• 

• 

• 

the Conectiv Acquisition which closed on July 1, 2010, and our York Energy Center which achieved COD in March 
2011; partially offset by
the negative impact in Texas of unplanned outages at some of our power plants caused by an extreme cold weather 
event in early February 2011, which required us to purchase physical replacement power at prices substantially above 
our hedged price;
lower Spark Spreads in our West segment resulting from a significant increase in hydroelectric generation in California 
in 2011 compared to 2010; and 
the expiration of certain hedge contracts which benefited the year ended December 31, 2010.

Our average total MW in operation increased by 2,241 MW, or 9%, primarily due to the Conectiv Acquisition which 
closed on July 1, 2010 and our York Energy Center which achieved COD in March 2011 partially offset by the sale of a 25% 
undivided interest in the assets of our Freestone power plant in December 2010. Generation increased 3% due primarily to higher 
generation in the North due to the Conectiv Acquisition and our York Energy Center and higher generation in Texas driven by 
extreme heat and drought conditions during the third quarter of 2011. The increase in generation was partially offset by lower 
generation in the West resulting from weaker price conditions which also largely contributed to a 4% decrease in our average 
capacity factor, excluding peakers in 2011 compared to 2010. 

Unrealized mark-to-market gain/loss from hedging our future generation and fuel needs had an unfavorable variance of 
$168 million primarily driven by the realization of favorable hedge positions in 2011 reported in unrealized mark-to-market gain/
loss at December 31, 2010, resulting in an unfavorable year-over-year change partially offset by unrealized gains on fuel and 
purchased energy positions reported at December 31, 2011.

Other revenue decreased for the year ended December 31, 2011, compared to the year ended December 31, 2010, due 
primarily to a decrease in other revenue of $15 million due to an adjustment related to prior periods on a major maintenance 
contract which resulted in higher revenue recognized in the second quarter of 2010.

Plant operating expense increased by $36 million for the year ended December 31, 2011, compared to the year ended 
December 31, 2010. Our normal, recurring plant operating expense decreased $32 million and costs related to unscheduled outages 
decreased $22 million, due largely to insurance recoveries for the year ended December 31, 2011, compared to the year ended 
December 31, 2010. The increase in plant operating expense was primarily due to an increase of $28 million related to our Mid-
Atlantic assets acquired in the Conectiv Acquisition, an increase of $7 million related to our York Energy Center which achieved 
COD in March 2011, an increase of $41 million in major maintenance expense resulting from our plant outage schedule, an increase 
of $6 million in costs from scrap parts related to outages, an increase in costs of $5 million related to our voluntary departure 
incentive program which was initiated in the second quarter of 2011 and an increase of $3 million in stock-based compensation 
expense.

Depreciation and amortization expense decreased for the year ended December 31, 2011, compared to the year ended 
December 31, 2010, primarily resulting from a decrease of $39 million due to rotable parts being fully depreciated for some of 
our units, a decrease of $17 million related to a revision in the expected settlement dates of the asset retirement obligations of our 
power plants and a decrease of $5 million due to the sale of a 25% undivided interest in the assets of our Freestone power plant 
in December 2010. The decrease was partially offset by an increase of $24 million related to our Mid-Atlantic assets acquired in 
the Conectiv Acquisition, an increase of $6 million related to York Energy Center which achieved COD in March 2011 and an 
increase of $11 million related to depreciation for assets placed into service during 2011.

61

 
Sales, general and other administrative expense decreased for the year ended December 31, 2011, compared to the year 
ended December 31, 2010, primarily resulting from $26 million in Conectiv Acquisition-related costs incurred during the year 
ended December 31, 2010. The decrease was partially offset by $10 million due to the reversal of a bad debt allowance in the first 
quarter of 2010 as a result of Lyondell Chemical Co.’s emergence from Chapter 11 bankruptcy and the bankruptcy court’s acceptance 
of our claim in the first quarter of 2010.

Other operating expenses decreased for the year ended December 31, 2011, compared to the year ended December 31, 
2010, resulting from a decrease of $10 million in operating lease expense due to our purchase from a third party of the entity that 
held the lease of South Point in December 2010 and a decrease of $3 million in royalty expense due to lower revenues from our 
Geysers Assets resulting from lower prices in 2011 compared to 2010.

Impairment losses for the year ended December 31, 2010 consisted of an impairment of approximately $95 million related 
to South Point (see Note 3 of the Notes to Consolidated Financial Statements for further information related to our acquisition of 
the South Point lease and subsequent impairment of our South Point assets) and approximately $21 million associated with two 
development projects that originated prior to our Chapter 11 bankruptcy proceedings. During the third quarter of 2010, we learned 
the projects would not receive PPAs that would support their continued development and made the determination that continued 
development was unlikely.

Gain on sale of assets, net consists of a $119 million gain recorded in the fourth quarter of 2010 related to the sale of a 
25% undivided interest in the assets of our Freestone power plant. See Note 3 of the Notes to Consolidated Financial Statements 
for further information.

Income from unconsolidated investments in power plants had a favorable variance for the year ended December 31, 2011, 
compared to the year ended December 31, 2010, primarily due to a $4 million year-over-year increase in operating income for 
Greenfield LP related to mechanical issues which impacted plant performance during the third quarter of 2010.

Interest expense decreased for the year ended December 31, 2011, compared to the year ended December 31, 2010, 
primarily due to a $45 million favorable change in unrealized mark-to-market activity related to the interest rate swaps hedging 
our variable rate debt that do not qualify for hedge accounting and a decrease of $7 million due to capitalized interest related to 
project debt for two of our facilities under construction. Also contributing to the favorable year-over-year change in interest expense 
was a decrease in our annual effective interest rate on our consolidated debt, excluding the impacts of capitalized interest and 
unrealized gains (losses) on interest rate swaps, which decreased to 7.6% for the year ended December 31, 2011, from 7.9% for 
the year ended December 31, 2010.

Loss on interest rate derivatives had a favorable change of $78 million for the year ended December 31, 2011, compared 
to the year ended December 31, 2010, primarily resulting from a year-over-year decrease of $115 million in historical unrealized 
losses previously deferred in AOCI and reclassified into income related to interest rate swaps formerly hedging our First Lien 
Credit Facility term loans. See Note 8 of the Notes to Consolidated Financial Statements for further discussion of our interest rate 
swaps formerly hedging our First Lien Credit Facility term loans. The favorable change was partially offset by an unfavorable 
year-over-year  change  of  approximately  $20  million  due  to  realized  interest  rate  swap  settlements  and  changes  in  fair  value 
subsequent to the reclassification date of the interest rate swaps formerly hedging our First Lien Credit Facility term loans. Also 
contributing to the unfavorable year-over-year change was an increase of $17 million resulting from interest rate swap breakage 
costs related to the repayment of project debt in June 2011. 

Debt extinguishment costs for the year ended December 31, 2011, primarily consisted of $74 million associated with the 
repayment of the NDH Project Debt in March 2011, $19 million associated with the retirement of the First Lien Credit Facility 
term loans in January 2011 in connection with the issuance of the 2023 First Lien Notes and $5 million related to the write-off of 
unamortized deferred financing costs related to the repayment of project debt in June 2011. Debt extinguishment costs for the year 
ended December 31, 2010, consisted of $61 million associated with the retirement of term loans under the First Lien Credit Facility 
in May, July and October 2010 in connection with the issuance of the 2019, 2020 and 2021 First Lien Notes and $30 million 
associated with the acquisition of the Broad River lease which was accounted for as a refinancing of existing debt under U.S. 
GAAP. See Note 3 of the Notes to Consolidated Financial Statements for further information regarding our acquisition of the 
Broad River lease. 

During the year ended December 31, 2011, we recorded an income tax benefit of $22 million compared to $68 million 
for the year ended December 31, 2010. The year-over-year change primarily resulted from an unfavorable variance in income tax 
expense of $128 million related to the application of intraperiod tax allocation and an increase in various state and foreign jurisdiction 
income taxes of $19 million for the year ended December 31, 2011, compared to the year ended December 31, 2010. The unfavorable 
variance in income tax expense was partially offset by a decrease in federal income tax of $101 million due primarily from a one-
time $76 million benefit to reduce our valuation allowance due to the election to consolidate the CCFC group with the Calpine 
group for 2011 for federal income tax reporting purposes and a decrease of $14 million due to the expiration of a statute of limitation 
62

related to an uncertain tax position. See Note 10 of the Notes to Consolidated Financial Statements for further discussion of the 
election to consolidate the CCFC group and the Calpine group for federal tax reporting purposes.

Income from discontinued operations for the year ended December 31, 2010, primarily consisted of $160 million associated 
with the gain, net of tax, on the sale of our 100% ownership interests in Blue Spruce and Rocky Mountain in December 2010. 
Also included in the income from discontinued operations for the year ended December 31, 2010, are the results of operations for 
Blue Spruce and Rocky Mountain. See Note 3 of the Notes to Consolidated Financial Statements for further discussion of our 
discontinued operations.

COMMODITY MARGIN AND ADJUSTED EBITDA

Management’s Discussion and Analysis of Financial Condition and Results of Operations includes financial information 
prepared in accordance with U.S. GAAP, as well as the non-GAAP financial measures, Commodity Margin and Adjusted EBITDA, 
discussed below, which we use as measures of our performance. Generally, a non-GAAP financial measure is a numerical measure 
of financial performance, financial position or cash flows that excludes (or includes) amounts that are included in (or excluded 
from) the most directly comparable measure calculated and presented in accordance with U.S. GAAP.

We use Commodity Margin, a non-GAAP financial measure, to assess our performance by our reportable segments. 
Commodity Margin includes our power and steam revenues, sales of purchased power and physical natural gas, capacity revenue, 
REC revenue, sales of surplus emission allowances, transmission revenue and expenses, fuel and purchased energy expense, fuel 
transportation expense, RGGI compliance and other environmental costs, and realized settlements from our marketing, hedging 
and optimization activities including natural gas transactions hedging future power sales, but excludes the unrealized portion of 
our mark-to-market activity and other revenues. We believe that Commodity Margin is a useful tool for assessing the performance 
of our core operations and is a key operational measure reviewed by our chief operating decision maker. Commodity Margin is 
not a measure calculated in accordance with U.S. GAAP and should be viewed as a supplement to and not a substitute for our 
results of operations presented in accordance with U.S. GAAP. Commodity Margin does not intend to represent income from 
operations, the most comparable U.S. GAAP measure, as an indicator of operating performance and is not necessarily comparable 
to similarly titled measures reported by other companies. See Note 16 of the Notes to Consolidated Financial Statements for a 
reconciliation of Commodity Margin to income (loss) from operations by segment.

West — Commodity Margin in our West segment decreased by $67 million, or 6%, for the year ended December 31, 
2012 compared to the year ended December 31, 2011, due to lower contribution from hedges, lower market power prices associated 
with our Geysers Assets which are based on absolute power price and lower revenue due to the expiration of contracts. The decrease 
was partially offset by an increase in Commodity Margin on our open position driven by higher market Spark Spreads and a 40% 
increase in generation driven primarily by improved market conditions, less hydroelectric generation and a nuclear power plant 
outage in California during 2012. Our average total MW in operation decreased 153 MW, or 2%, due primarily to the temporary 
shut down of our Los Esteros Critical Energy Facility at the end of 2011 associated with the upgrade from simple-cycle to combined-
cycle technology partially offset by an increase in capacity resulting from our turbine modernization program.

Texas — Commodity Margin in our Texas segment increased by $101 million, or 22%, for the year ended December 31, 
2012 compared to the year ended December 31, 2011, due to higher contribution from our hedging activities that secured favorable 
pricing despite lower settled market prices driven by milder weather primarily in the third quarter of 2012 compared to the same 
period in 2011. We also realized higher Commodity Margin from a 10% increase in generation in 2012 driven by lower natural 
gas prices. Generation increased as natural gas prices were low enough during certain periods in the first half of 2012 that some 
of our modern, natural gas-fired, combined-cycle power plants in Texas became less expensive on a marginal basis than coal-fired 
generation resulting in these plants running baseload. Also contributing to the year-over-year increase was the negative impact to 
Commodity Margin in the first quarter of 2011 due to unplanned outages at some of our power plants caused by an extreme cold 
weather event which occurred on February 2, 2011. Our average total MW in operation increased 139 MW due to the acquisition 
of  our  762  MW  Bosque  Energy  Center  in  the  fourth  quarter  of  2012  and  an  increase  in  capacity  resulting  from  our  turbine 
modernization program.

North — Commodity Margin in our North segment increased by $25 million, or 4%, for the year ended December 31, 
2012 compared to the year ended December 31, 2011, primarily due to our York Energy Center which achieved COD in March 
2011, higher contribution from hedges and a 40% increase in generation resulting from lower natural gas prices. During the year 
ended December 31, 2012, generation increased as natural gas prices were low enough that during certain periods some of our 
Mid-Atlantic modern, natural gas-fired, combined-cycle power plants became less expensive on a marginal basis than coal-fired 
generation resulting in these power plants running baseload. The increase in Commodity Margin was partially offset by lower 
regulatory capacity revenues and a decline in nodal pricing in PJM during the year ended December 31, 2012 compared to 2011. 
Average total MW in operation increased 107 MW, or 1%, due primarily to our 565 MW York Energy Center and an increase in 
capacity resulting from our turbine modernization program.

Southeast — Commodity Margin in our Southeast segment increased by $5 million, or 2%, for the year ended December 
31, 2012 compared to the year ended December 31, 2011, primarily due to higher contribution from hedges and an 11% increase 
in generation largely driven by lower natural gas prices. The increase in Commodity Margin was largely offset by the negative 
impact from the expiration of a contract during the third quarter of 2012.

West — Commodity Margin in our West segment for the year ended December 31, 2011 was comparable to the year 
ended December 31, 2010. During the year ended December 31, 2011, we experienced higher Commodity Margin contribution 
from hedges as well as the positive impact of origination activities in 2011 compared to 2010. These positive factors were offset 
by lower Spark Spreads resulting from a significant increase in hydroelectric generation in California in 2011 compared to 2010, 
and lower Commodity Margin resulting from an unscheduled outage at OMEC during the second quarter of 2011. Consistent with 
weaker price conditions, generation decreased 23% for the year ended December 31, 2011 compared to 2010. Average availability 
decreased by 4% due to an increase in the duration of outages during the second quarter of 2011 compared to the second quarter 
of 2010, as the weaker price environment provided an opportunity to extend the duration of scheduled maintenance outages due 
to limited opportunity costs. Our average total MW in operation decreased 16 MW primarily due to the retirement of our Pittsburg 
power plant in March 2010 as well as the expiration of our operating lease and subsequent retirement of our Watsonville (Monterey) 
cogeneration power plant in May 2010 which was partially offset by an increase related to the completion of turbine modernizations 
at two of our power plants in 2011.

Texas — Commodity Margin in our Texas segment decreased by $35 million, or 7%, for the year ended December 31, 
2011, compared to the year ended December 31, 2010. Despite an increase in Commodity Margin contributions from hedges, 
Commodity Margin was negatively impacted by unplanned outages at some of our power plants caused by an extreme cold weather 
event which occurred on February 2, 2011. Power prices increased dramatically as a result of the cold weather event and the plant 
outages,  which  required  us  to  purchase  physical  replacement  power  at  prices  substantially  above  our  hedged  prices. Also 
contributing to the year-over-year decrease in Commodity Margin was the sale of a 25% undivided interest in the assets of our 
Freestone power plant in December 2010 which also drove a 178 MW, or 2%, decrease in our average total MW in operation 
which was partially offset by an increase related to the completion of turbine modernizations at several of our power plants in 
2011 and 2010. The decrease in Commodity Margin was partially offset by significantly higher power prices driven by extreme 
heat and drought conditions which increased Spark Spreads during the third quarter of 2011 on our relatively small open position.

North — Commodity Margin in our North segment increased by $169 million, or 32%, primarily due to the Conectiv 
Acquisition which closed on July 1, 2010 and our York Energy Center which achieved COD in March 2011 which were both also 
the primary driver of the year-over-year increase in generation as well as the 2,435 MW increase in average total MW in operation 
during the year ended December 31, 2011 compared to the year ended December 31, 2010. The increase in Commodity Margin 
was partially offset by lower capacity prices in the second half of 2011 compared to the same period in 2010. Average capacity 
factor, excluding peakers, increased 9% primarily due to scheduled outages at two of our power plants in the fourth quarter of 
2010.

Southeast — Commodity Margin in our Southeast segment decreased by $32 million, or 12%, for the year ended December 
31, 2011 compared to the year ended December 31, 2010 largely due to the expiration of certain hedge contracts which benefited 
the year ended December 31, 2010 as well as lower Commodity Margin that resulted from unscheduled outages that occurred 
during the second and third quarters of 2011.

Adjusted EBITDA

We define Adjusted EBITDA as EBITDA adjusted for certain items described below and presented in the accompanying 
reconciliation. Adjusted EBITDA is not a measure calculated in accordance with U.S. GAAP, and should be viewed as a supplement 
to and not a substitute for our results of operations presented in accordance with U.S. GAAP. Our Corporate Revolving Facility 
includes a similar measure as a basis for our material covenants under the debt agreement that excludes our net interest in our 
unconsolidated  subsidiaries  and  includes  distributions  received  from  unconsolidated  investments.  However,  we  believe  that 
inclusion of our share of the Adjusted EBITDA of our unconsolidated subsidiaries is useful in evaluating our overall performance 
and therefore we include Adjusted EBITDA from our unconsolidated investments and exclude distributions received from our 
unconsolidated investments in our definition of Adjusted EBITDA. Adjusted EBITDA is not intended to represent cash flows from 
operations or net income (loss) as defined by U.S. GAAP as an indicator of operating performance. Furthermore, Adjusted EBITDA 
is not necessarily comparable to similarly-titled measures reported by other companies.

We believe Adjusted EBITDA is also used by and is useful to investors and other users of our financial statements in 
evaluating our operating performance because it provides them with an additional tool to compare business performance across 
companies and across periods. We believe that EBITDA is widely used by investors to measure a company’s operating performance 
without regard to items such as interest expense, taxes, depreciation and amortization, which can vary substantially from company 
to company depending upon accounting methods and book value of assets, capital structure and the method by which assets were 
acquired.

Additionally, we believe that investors commonly adjust EBITDA information to eliminate the effect of restructuring 
and other expenses, which vary widely from company to company and impair comparability. As we define it, Adjusted EBITDA 
represents EBITDA adjusted for the effects of impairment losses, gains or losses on sales, dispositions or retirements of assets,

any unrealized gains or losses from accounting for derivatives, stock-based compensation expense, operating lease expense, non-
cash  gains  and  losses  from  foreign  currency  translations,  major  maintenance  expense,  gains  or  losses  on  the  repurchase  or 
extinguishment of debt, Conectiv Acquisition-related costs and any extraordinary, unusual or non-recurring items plus the Adjusted 
EBITDA from our discontinued operations and adjustments to reflect the Adjusted EBITDA from our unconsolidated investments. 
We adjust for these items in our Adjusted EBITDA as our management believes that these items would distort their ability to 
efficiently view and assess our core operating trends.

In summary, our management uses Adjusted EBITDA as a measure of operating performance to assist in comparing 
performance from period to period on a consistent basis and to readily view operating trends, as a measure for planning and 
forecasting overall expectations and for evaluating actual results against such expectations, and in communications with our Board 
of Directors, shareholders, creditors, analysts and investors concerning our financial performance.

The tables below provide a reconciliation of Adjusted EBITDA to our income (loss) from operations on a segment basis 
and to net income (loss) attributable to Calpine on a consolidated basis for years ended December 31, 2012, 2011 and 2010 (in 
millions).

LIQUIDITY AND CAPITAL RESOURCES

Our  business  is  capital  intensive.  Our  ability  to  successfully  implement  our  strategy  is  dependent  on  the  continued 
availability of capital on attractive terms. In addition, our ability to successfully operate our business is dependent on maintaining 
sufficient liquidity. We believe that we have adequate resources from a combination of cash and cash equivalents on hand and 
cash expected to be generated from future operations to continue to meet our obligations as they become due.

Liquidity

At December 31, 2012, we had $1,284 million in cash and cash equivalents and $253 million of restricted cash. Amounts 
available for future borrowings were $757 million under our Corporate Revolving Facility. The following table provides a summary 
of our liquidity position at December 31, 2012 and 2011 (in millions):

____________

(1) 

(2) 

Includes $11 million and $34 million of margin deposits held by us posted by our counterparties at December 31, 2012 and 
2011, respectively.

Includes availability under our CDHI letter of credit facility. On January 10, 2012, we increased the CDHI letter of credit 
facility to $300 million and extended the maturity date to January 2, 2016. As a result of the completion of the sale of 
Riverside  Energy  Center,  LLC,  a  wholly-owned  subsidiary  of  CDHI,  on  December  31,  2012,  we  are  required  to  cash 
collateralize letters of credit issued in excess of $225 million until replacement collateral is contributed to the CDHI collateral 
package which we are in the process of arranging. At December 31, 2012, we had $28 million of cash collateral posted in 
support of outstanding letters of credit under our CDHI letter of credit facility. We do not believe that this change will have 
a material impact on our liquidity.

Our principal source for future liquidity is cash flows generated from our operations. Our principal uses of liquidity and 
capital resources, outside of those required for our operations, include, but are not limited to, collateral requirements to support 
our commercial hedging and optimization activities, debt service obligations including principal and interest payments and capital 
expenditures for construction, project development and other growth initiatives. In addition, we may use capital resources to 
opportunistically repurchase our shares of common stock. The ultimate decision to allocate capital to share repurchases will be 
based upon the expected returns compared to alternative uses of capital. We believe that cash on hand and expected future cash 
flows from operations will be sufficient to meet our liquidity needs for our operations, both in the near and longer term.

Cash Management — We manage our cash in accordance with our cash management system subject to the requirements 
of our Corporate Revolving Facility and requirements under certain of our project debt and lease agreements or by regulatory 
agencies. Our cash and cash equivalents, as well as our restricted cash balances are invested in money market accounts with 
investment banks that are not FDIC insured. We place our cash, cash equivalents and restricted cash in what we believe to be 
creditworthy financial institutions and certain of our money market accounts invest in U.S. Treasury securities or other obligations 
issued or guaranteed by the U.S. Government, its agencies or instrumentalities.

We have never paid cash dividends on our common stock. Future cash dividends, if any, will be at the discretion of our 
Board of Directors and will depend upon, among other things, our future operations and earnings, capital requirements, general 
financial condition, contractual and financing restrictions and such other factors as our Board of Directors may deem relevant.

71

 
Liquidity Sensitivity

Significant changes in commodity prices and Market Heat Rates can have an impact on our liquidity as we use margin 
deposits, cash prepayments and letters of credit as credit support (collateral) with and from our counterparties for commodity 
procurement and risk management activities. Utilizing our portfolio of transactions subject to collateral exposure, we estimate 
that as of January 18, 2013, an increase of $1/MMBtu in natural gas prices would result in an increase of collateral required by 
approximately $52 million. If natural gas prices decreased by $1/MMBtu, we estimate that our collateral requirements would 
increase by approximately $69 million. Changes in Market Heat Rates also affect our liquidity. For example, as demand increases, 
less efficient generation is dispatched, which increases the Market Heat Rate and results in increased collateral requirements. 
Historical relationships of natural gas and Market Heat Rate movements for our portfolio of assets have been volatile over time 
and are influenced by the absolute price of natural gas and the regional characteristics of each power market. We estimate that at 
January 18, 2013, an increase of 500 Btu/KWh in the Market Heat Rate would result in an increase in collateral required by 
approximately $30 million. If Market Heat Rates were to fall at a similar rate, we estimate that our collateral required would 
decrease by $28 million. These amounts are not necessarily indicative of the actual amounts that could be required, which may 
be higher or lower than the amounts estimated above, and also exclude any correlation between the changes in natural gas prices 
and Market Heat Rates that may occur concurrently. These sensitivities will change as new contracts or hedging activities are 
executed.

In order to effectively manage our future Commodity Margin, historically we have economically hedged a portion of 
our generation and natural gas portfolio mostly through power and natural gas forward physical and financial transactions; however, 
we currently remain susceptible to significant price movements for 2013 and beyond. In addition to the price of natural gas, the 
future impact on our Commodity Margin is highly dependent on other factors such as:

• 

• 

• 

the level of Market Heat Rates;

our continued ability to successfully hedge our Commodity Margin;

the speed, strength and duration of an economic recovery;

•  maintaining acceptable availability levels for our fleet;

• 

• 

• 

• 

the impact of current and pending environmental regulations in the markets in which we participate;

improving the efficiency and profitability of our operations;

increasing future contractual cash flows; and

our significant counterparties performing under their contracts with us.

Additionally, scheduled outages related to the life cycle of our power plant fleet in addition to unscheduled outages may 
result in maintenance expenditures that are disproportionate in differing periods. In order to manage such liquidity requirements, 
we maintain additional liquidity availability in the form of our Corporate Revolving Facility (noted in the table above), letters of 
credit and the ability to issue first priority liens for collateral support. It is difficult to predict future developments and the amount 
of credit support that we may need to provide should such conditions occur, we experience another economic recession or energy 
commodity prices increase significantly. 

Our letters of credit, capital management, construction, upgrades and growth initiatives are further discussed below.

Letter of Credit Facilities

Capital Management and Significant Financing Transactions

In connection with our goals of enhancing long-term shareholder value and leveraging our three scale regions, we have 
completed, initiated or made progress toward completing the following key capital and financing transactions during 2012, as 
further described below.

72

2019 First Lien Term Loan

On October 9, 2012, we entered into and borrowed $835 million under our 2019 First Lien Term Loan, which bears 
interest, at our option, at either (i) the base rate, equal to the higher of the Federal Funds effective rate plus 0.5% per annum or 
the Prime Rate (as such terms are defined in the 2019 First Lien Term Loan credit agreement), plus an applicable margin of 2.25%, 
or (ii) LIBOR plus 3.25% per annum subject to a LIBOR floor of 1.25%. We used the net proceeds received to redeem 10% of 
the aggregate principal amount of each series of our existing First Lien Notes at a redemption price of 103% of the principal 
amount redeemed and to repay project debt totaling $218 million, plus accrued and unpaid interest for each. The 2019 First Lien 
Term Loan allows us to reduce our overall cost of debt by replacing a portion of our First Lien Notes with fixed interest rates 
ranging from 7.25% to 8.0% with a corporate level term loan carrying a lower variable interest rate currently at 4.5% and to repay 
variable rate project debt. The 2019 First Lien Term Loan carries substantially the same terms as the First Lien Term Loans and 
matures on October 9, 2019. The 2019 First Lien Term Loan also contains substantially similar covenants, qualifications, exceptions 
and limitations as the First Lien Term Loans and First Lien Notes.

Acquisition of Bosque Energy Center

On November 7, 2012, we, through our indirect, wholly-owned subsidiary Calpine Bosque Energy Center, LLC, completed 
the purchase of a power plant with a nameplate capacity of 800 MW owned by Bosque Power Co., LLC, for approximately $432 
million. The modern, natural gas-fired, combined-cycle power plant increased capacity in our Texas segment and is located in 
Central Texas near the unincorporated community of Laguna Park in Bosque County. The site includes a 250 MW generation 
block with one natural-gas turbine, one heat recovery steam generator and one steam turbine that achieved COD in June 2001 and 
a 550 MW generation block with two natural-gas turbines that went online in June 2000 as well as two heat recovery steam 
generators and one steam turbine that achieved COD in June 2011. We funded the $432 million purchase price with cash on hand. 

Sale of Riverside Energy Center

Our 603 MW Riverside Energy Center had a PPA that provided WP&L an option to purchase the power plant and plant-
related assets upon written notice of exercise prior to May 31, 2012. On May 18, 2012, WP&L exercised their option to purchase 
Riverside Energy Center, LLC, one of our VIEs which owned Riverside Energy Center. The sale closed on December 31, 2012 
for approximately $402 million, and we recorded a pre-tax gain of approximately $7 million, which is included in (gain) on sale 
of assets, net on our Consolidated Statements of Operations. We expect to use the sale proceeds for our capital allocation activities 
and for general corporate purposes.

Sale of Broad River

On December 27, 2012, we, through our indirect, wholly-owned subsidiary Calpine Power Company, completed the sale 
of 100% of our ownership interest in each of the Broad River Entities for approximately $423 million. This transaction resulted 
in the disposition of our Broad River power plant, an 847 MW natural gas-fired, peaking power plant located in Gaffney, South 
Carolina, and includes a five year consulting agreement with the buyer. We recorded a pre-tax gain of approximately $215 million 
in December 2012, which is included in (gain) on sale of assets, net on our Consolidated Statements of Operations.We expect to 
use the sale proceeds for our capital allocation activities and for general corporate purposes.

CDHI

On January 10, 2012, we increased the CDHI letter of credit facility to $300 million and extended the maturity date to 
January 2, 2016. As a result of the completion of the sale of Riverside Energy Center, LLC, a wholly-owned subsidiary of CDHI, 
on December 31, 2012, we are required to cash collateralize letters of credit issued in excess of $225 million until replacement 
collateral is contributed to the CDHI collateral package which we are in the process of arranging. At December 31, 2012, we had 
$28 million of cash collateral posted in support of outstanding letters of credit under our CDHI letter of credit facility. We do not 
believe that this change will have a material impact on our liquidity.

Share Repurchase Program

On August 23, 2011, we announced that our Board of Directors had authorized the repurchase of up to $300 million in 
shares of our common stock. In April 2012, our Board of Directors authorized us to double the size of our share repurchase program, 
increasing our permitted cumulative repurchases to $600 million in shares of our common stock. As of the filing of this Report, 
we have completed our previously announced $600 million share repurchase program, having repurchased a total of 35,568,833 
shares of our outstanding common stock at an average price paid of $16.87 per share. In February 2013, our Board of Directors 
authorized the repurchase of an additional $400 million in shares of our common stock, bringing the cumulative authorization 
total to $1.0 billion.

73

Construction, Modernizations and Growth Initiatives

We remain focused on our goal to continue to grow our presence in core markets with an emphasis on expansions or 
modernizations of existing power plants. We intend to take advantage of favorable opportunities to continue to design, develop, 
acquire, construct and operate the next generation of highly efficient, operationally flexible and environmentally responsible power 
plants where such investment meets our rigorous financial hurdles, particularly if power contracts and financing are available and 
attractive returns are expected. Likewise, we will actively seek divestiture opportunities on our non-core assets if those opportunities 
meet our financial expectations. In addition, we believe that modernizations and expansions to our current assets or using existing 
equipment  offer  proven  and  financially  disciplined  opportunities  to  improve  our  operations,  capacity  and  efficiencies.  Our 
significant projects under construction, growth initiatives and modernizations are discussed below.

West:

Russell  City  Energy  Center  —  Construction  at  our  Russell  City  Energy  Center  continues  to  move  forward.  Upon 
completion, this project will bring on line approximately 429 MW of net interest baseload capacity (464 MW with peaking capacity) 
representing our 75% share. Construction is ongoing and COD is expected in the summer of 2013. Upon completion, the Russell 
City Energy Center is contracted to deliver its full output to PG&E under a ten-year PPA.

Los Esteros Critical Energy Facility — During 2009, we and PG&E negotiated a new PPA to replace the existing California 
Department of Water Resources contract and facilitate the modernization of our Los Esteros Critical Energy Facility from a 188 
MW simple-cycle generation power plant to a 309 MW combined-cycle generation power plant, which will also increase the 
efficiency and environmental performance of the power plant by lowering the Heat Rate. Construction is ongoing and COD is 
expected in the summer of 2013.

Texas:

Channel and Deer Park Expansions — In September and November 2011, we filed air permit applications with the 
TCEQ and the EPA to expand the baseload capacity of the Deer Park and Channel Energy Centers by approximately 260 MW 
each. We received air permit approvals from the TCEQ for our Deer Park and Channel expansion projects in September and 
October 2012, respectively, and from the EPA in November 2012. Construction on these expansion projects commenced in the 
fourth quarter of 2012. We expect COD during the summer of 2014 for these expansions and are currently evaluating funding 
sources including, but not limited to, nonrecourse financing, corporate financing or internally generated funds.

North:

Garrison Energy Center — We are actively permitting 618 MW of new combined-cycle capacity at a development site 
secured by a long-term lease with the City of Dover. For the first phase (309 MW), we have executed the Interconnection Services 
Agreement  and  the  Interconnection  Construction  Services Agreement  with  PJM.  For  the  second  phase  (309  MW),  we  have 
completed a feasibility study and are currently conducting a system impact study. Environmental permitting, site development 
planning and development engineering are underway and the first phase’s capacity cleared PJM’s 2015/2016 base residual auction. 
We  received  the  air  permit  and  executed  a  preliminary  notice  to  proceed  for  the  engineering,  procurement  and  construction 
agreement during the first quarter of 2013. We expect COD for the first phase by the summer of 2015 and are currently evaluating 
funding sources including, but not limited to, nonrecourse financing, corporate financing or internally generated funds. 

All Segments:

Turbine Modernization — We continue to move forward with our turbine modernization program. Through December 31, 
2012, we have completed the upgrade of eleven Siemens and eight GE turbines totaling over 200 MW and have committed to 
upgrade approximately three additional turbines.

2012 — 2011 

Net Cash Provided By Operating Activities 

Cash provided by operating activities for the year ended December 31, 2012, was $653 million compared to $775 million 

for the year ended December 31, 2011. The decrease in cash provided by operating activities was primarily due to: 

•  Working capital — Working capital employed increased by approximately $58 million for the year ended December 
31, 2012 compared to 2011 after adjusting for debt related balances and non-hedging interest rate swaps which did 
not impact cash provided by operating activities. The increase was primarily due to increased margin requirements 
during the year ended December 31, 2012.

• 

Interest paid — Cash paid for interest increased by $63 million to $719 million for the year ended December 31, 
2012, as compared to $656 million for 2011. The increase was primarily due to timing of interest payments on our 
First Lien Notes and First Lien Term Loans partially offset by lower payments on our NDH Project Debt and other 
project debt.

•  Prepayment premiums — For the year ended December 31, 2012, we paid $29 million in prepayment premiums 
related to a repayment of a portion of our First Lien Notes and our variable rate project debt compared to $13 million 
in prepayment premiums related to the extinguishment of the NDH Project Debt for the year ended December 31, 
2011.

•  Ground lease modification — For the year ended December 31, 2012, we paid $28 million related to a renegotiated 

ground lease at one of our operating plants. We made no similar payments for the year ended December 31, 2011.

75

 
 
Our decrease in cash provided by operating activities was partially offset by the following:

• 

Income from operations — Income from operations, adjusted for non-cash items increased by $45 million for the 
year  ended  December  31,  2012,  as  compared  to  2011.  Non-cash  items  consist  primarily  of  depreciation  and 
amortization,  gains  and  losses  on  sales  of  assets,  impairment  losses,  income  and  losses  from  unconsolidated 
investments and unrealized gains and losses in mark-to-market activity.

Net Cash Used In Investing Activities 

Cash flows used in investing activities for the year ended December 31, 2012, was $470 million compared to cash flows 

used in investing activities of $836 million for the year ended December 31, 2011. The decrease was primarily due to: 

•  Capital  expenditures  —  Payments  made  for  capital  expenditures  for  the  year  ended  December  31,  2012,  were 
approximately $637 million, compared to payments of approximately $683 million for the year ended December 31, 
2011. The year-over-year decrease was primarily due to the timing of cash payments. 

•  Higher proceeds from sales of power plants, interests and other — For the year ended December 31, 2012, we 
received proceeds of approximately $825 million related to the sale of 100% of our ownership interests in each of 
the Broad River Entities and the sale of our Riverside Energy Center, compared to proceeds of approximately $13 
million from the disposition of other plant assets for the year ended December 31, 2011.

• 

• 

Settlement of non-hedging interest rate swaps — During the year ended December 31, 2012 we terminated our legacy 
interest rate swaps formerly hedging our First Lien Credit Facility resulting in payments of $156 million, compared 
to payments of $189 million during the same period in 2011. 

Transmission credits — During the year ended December 31, 2012, we paid $12 million for transmission credits 
related to the construction of our Russell City Energy Center compared to $31 million paid during the year ended 
December 31, 2011.

The decrease in cash flows used in investing activities was partially offset by:

•  Purchase of power plant — In 2012 we purchased a natural gas-fired, combined-cycle power plant located in Bosque 

County, Texas for approximately $432 million. There were no acquisitions in 2011. 

•  Restricted cash — Restricted cash increased by $59 million for the year ended December 31, 2012, compared to a 
decrease of $54 million for the same period in 2011. The increase was primarily due to additional cash collateral 
requirements related to the change in capacity under the CDHI letter of credit facility associated with the completion 
of the sale of the Riverside Energy Center. The decrease in restricted cash in 2011 was primarily due to the maturity 
of project debt and the corresponding reduction in restricted cash requirements.

Net Cash Used In Financing Activities 

Cash flows used in financing activities were $151 million for the year ended December 31, 2012, compared to $14 million 

for the year ended December 31, 2011. The increase in cash flows used in financing activities was primarily due to:

• 

Lower net borrowings under the First Lien Term Loans — During the year ended December 31, 2012, we received 
proceeds of approximately $835 million from the issuance of the 2019 First Lien Term Loan, an $822 million decrease 
compared to the $1.7 billion in proceeds received from the 2018 First Lien Term Loans issued in the year ended 
December 31, 2011. 

•  Repayments of First Lien Term Loans — During the year ended December 31, 2012, we redeemed 10% of the 
aggregate principal amount of each series of our existing First Lien Notes for approximately $590 million and made 
no similar redemption during the year ended December 31, 2011. The redemption in 2012 was funded from the $835 
million in proceeds received from the issuance of the 2019 First Lien Term Loan.

• 

Stock repurchases — During the year ended December 31, 2012, we made payments under the share repurchase 
program of approximately $463 million, compared to payments of approximately $119 million for the year ended 
December 31, 2011.

•  Decreased  contributions  from  noncontrolling  interest  holder  —  During  the  year  ended  December  31,  2012,  we 
received no proceeds from a noncontrolling interest holder in Russell City Energy Company, LLC, compared to 
approximately $33 million for the year ended December 31, 2011.

76

The increase in cash flows used in financing activities was partially offset by:

•  Repayments on NDH Project Debt — During the year ended December 31, 2012, we made no repayments on the 
NDH Project Debt, compared to payments of approximately $1.3 billion for the year ended December 31, 2011. This 
repayment was funded by the $1.7 billion in proceeds received from the issuance of the 2018 First Lien Term Loans 
during the year ended December 31, 2011. 

• 

• 

• 

Lower repayments of project debt, notes payable and other — During the year ended December 31, 2012, we made 
repayments of approximately $289 million, primarily due to the retirement of the BRSP project debt. During the 
year ended December 31, 2011, we made repayments of $550 million, primarily due to the repayment of the Deer 
Park and Metcalf project debt.

Increased proceeds from project debt, notes payable and other — During the year ended December 31, 2012, we 
received proceeds of approximately $389 million related to our Russell City Project Debt and Los Esteros Project 
Debt, compared to $327 million for the same period in 2011.

Lower financing costs — During the year ended December 31, 2012, we paid financing costs of approximately $20 
million compared to approximately $81 million for the year ended December 31, 2011.

2011 — 2010

Net Cash Provided By Operating Activities 

Cash provided by operating activities for the year ended December 31, 2011, was $775 million compared to $929 million 

for the year ended December 31, 2010. The decrease in cash provided by operating activities was primarily due to: 

•  Working capital — Working capital employed increased by approximately $194 million for the year ended December 
31, 2011 compared to 2010 after adjusting for debt related balances and non-hedging interest rate swaps which did 
not impact cash provided by operating activities. The increase was primarily due to a reduction in margin requirements 
during the year ended December 31, 2010.

• 

Interest paid — Cash paid for interest, inclusive of interest rate swaps in hedging relationships, increased by $21 
million to $656 million for the year ended December 31, 2011, as compared to $635 million for 2010. The increase 
was primarily due to timing of interest payments on our First Lien Notes and 2018 First Lien Term Loans as compared 
to the previously outstanding First Lien Credit Facility and project debt.

•  Prepayment premiums — For the year ended December 31, 2011, we paid $13 million of prepayment premiums 

related to the extinguishment of the NDH Project Debt.

Our decrease in cash provided by operating activities was partially offset by the following:

• 

Income from operations — Income from operations, adjusted for non-cash items increased by $41 million for the 
year  ended  December  31,  2011,  as  compared  to  2010.  Non-cash  items  consist  primarily  of  depreciation  and 
amortization,  gains  and  losses  on  sales  of  assets,  impairment  losses,  income  and  losses  from  unconsolidated 
investments and unrealized gains and losses in mark-to-market activity.

Net Cash Used In Investing Activities 

Cash flows used in investing activities for the year ended December 31, 2011, were $836 million compared to cash flows 

used in investing activities of $831 million for the year ended December 31, 2010. The difference was primarily due to: 

•  Purchase of Conectiv assets and BRSP — We purchased the Conectiv assets and BRSP for approximately $1.7 billion 

in 2010. There were no acquisitions in 2011. 

•  Capital expenditures — Capital expenditures increased by $314 million primarily resulting from construction activity 
at the Russell City Energy Center, Los Esteros Critical Energy Facility and York Energy Center combined with our 
turbine modernization program. 

• 

• 

Lower proceeds from sales of power plants, interests and other — For the year ended December 31, 2011, we received 
proceeds of approximately $13 million from the disposal of other plant assets compared to proceeds of approximately 
$954 million primarily relating to the sale of Blue Spruce, Rocky Mountain and a 25% undivided interest in the 
assets of our Freestone power plant for the year ended December 31, 2010.

Settlement of non-hedging interest rate swaps — During the year ended December 31, 2011 we made payments on 
interest rate swap derivative instruments associated with swaps that formerly hedged variable rate debt which was 
converted to fixed rate debt of $189 million compared to payments of $69 million during the same period in 2010.

77

•  Restricted  cash  — The  net  decrease  in  restricted  cash  was  $54  million  for  the  year  ended  December  31,  2011, 
compared to $322 million for the same period in 2010. The decrease in restricted cash in 2011 as compared to 2010 
was primarily due to the maturity of project debt and the corresponding reduction in restricted cash requirements.

• 

Transmission credits — During the year ended December 31, 2011, we paid $31 million for transmission credits 
related to construction of our Russell City Energy Center.

Net Cash Provided By (Used In) Financing Activities 

Cash flows used in financing activities were $14 million for the year ended December 31, 2011, compared to cash flows 
provided by financing activities of $240 million for the year ended December 31, 2010. The change in cash flows provided by 
(used in) financing activities was primarily related to:

• 

• 

Issuance of the 2018 First Lien Term Loans — During the year ended December 31, 2011, we received proceeds of 
approximately $1.7 billion from the issuance of the 2018 First Lien Term Loans. We used the proceeds to repay our 
NDH Project Debt of approximately $1.3 billion resulting in a net increase of $374 million.

Issuance of the First Lien Notes — We received proceeds of approximately $1.2 billion from the issuance of the 
2023 First Lien Notes and used those proceeds to terminate the First Lien Credit Facility in accordance with its 
repayment terms resulting in a net increase of $5 million during the year ended December 30, 2011, compared to a 
net increase of $14 million during the year ended December 31, 2010.

•  Reduced  proceeds  from  project  debt  —  During  the  year  ended  December  31,  2011,  we  received  proceeds  of 
approximately $327 million related to our Russell City Project Debt and Los Esteros Project Debt. During 2010 we 
received proceeds of approximately $1.3 billion to fund the Conectiv Acquisition.

• 

• 

Lower repayments of project debt — During the year ended December 31, 2011, we made repayments on project 
debt of approximately $550 million, compared to approximately $937 million for the year ended December 31, 2010.

Increased contributions from noncontrolling interest holder — During the year ended December 31, 2011, we received 
proceeds of approximately $34 million from a noncontrolling interest holder in Russell City Energy Center, compared 
to contributions of approximately $17 million for the year ended December 31, 2010.

•  Decreased finance costs — During the year ended December 31, 2011, primarily due to the refinancing of the First 
Lien Credit Facility and the NDH Project Debt, we incurred $81 million in finance costs primarily related to the 
issuance of the First Lien Notes and project debt, compared to $136 million in finance costs primarily related to the 
issuance of the First Lien Notes and project debt.

• 

Stock repurchases — During the year ended December 31, 2011, we made payments of approximately $119 million 
under the share repurchase program announced on August 23, 2011. There were no similar repurchases during the 
same period in 2010.

Counterparties and Customers

Our counterparties primarily consist of three categories of entities who participate in the wholesale energy markets: 
financial institutions and trading companies; regulated utilities, municipalities, cooperatives, ISOs and other retail power suppliers; 
and oil, natural gas, chemical and other energy-related industrial companies. We have exposure to trends within the energy industry, 
including declines in the creditworthiness of our counterparties. We have concentrations of credit risk with a few of  our commercial 
customers relating to our sales of power, steam and hedging and optimization activities. Currently, certain of our counterparties 
within  the  energy  industry  have  below  investment  grade  credit  ratings.  We  believe  that  our  credit  policies  and  portfolio  of 
transactions adequately monitor and diversify our credit risk, and currently our counterparties are performing and financially 
settling timely according to their respective agreements.  

Credit Considerations

Our  credit  rating  has,  among  other  things,  generally  required  us  to  post  significant  collateral  with  our  hedging 
counterparties. Our collateral is generally in the form of cash deposits, letters of credit or first liens on our assets. See also Note 
9 of the Notes to Consolidated Financial Statements for our use of collateral. Our credit rating has also reduced the number of 
hedging counterparties willing to extend credit to us and reduced our ability to negotiate more favorable terms with them. However, 
we believe that we will continue to be able to work with our hedging counterparties to execute beneficial hedging transactions 
and provide adequate collateral. At December 31, 2012, our First Lien Notes, First Lien Term Loans, Corporate Revolving Facility 
and our corporate rating had the following ratings and commentary from Standard and Poor’s and Moody’s Investors Service:

Off Balance Sheet Arrangements

Our power plant operating leases are not reflected on our Consolidated Balance Sheets and contain customary restrictions 
on dividends up to Calpine Corporation, additional debt and further encumbrances similar to those typically found in project 
finance debt instruments. See Note 15 of the Notes to Consolidated Financial Statements for the future minimum lease payments 
under our power plant operating leases.

Some of our unconsolidated equity method investments have debt that is not reflected on our Consolidated Balance 
Sheets. As of December 31, 2012, our equity method investees (Greenfield LP and Whitby) had aggregate debt outstanding of 
$448 million. Based on our pro rata share of each of the investments, our share of such debt would be approximately $224 million. 
All such debt is non-recourse to us. See Note 5 of the Notes to Consolidated Financial Statements for additional information on 
our investments.

Guarantee Commitments — As part of our normal business operations, we enter into various agreements providing, or 
otherwise arranging, financial or performance assurance to third parties on behalf of our subsidiaries in the ordinary course of 
such subsidiaries’ respective business. Such arrangements include guarantees, standby letters of credit and surety bonds for power 
and  natural  gas  purchase  and  sale  arrangements  and  contracts  associated  with  the  development,  construction,  operation  and 
maintenance of our fleet of power plants. These arrangements are entered into primarily to support or enhance the creditworthiness 
otherwise attributed to a subsidiary on a stand-alone basis, thereby facilitating the extension of sufficient credit to accomplish the 
subsidiaries’ intended commercial purposes. Our primary commercial obligations as of December 31, 2012, are as follows (in 
millions):

Special Purpose Subsidiaries

Pursuant  to  applicable  transaction  agreements,  we  have  established  certain  of  our  entities  separate  from  Calpine 
Corporation and our other subsidiaries. In accordance with applicable accounting standards, we consolidate these entities. As of 
the date of filing of this Report, these entities included: GEC Holdings, LLC, Gilroy Energy Center, LLC, Creed, Goose Haven, 
Calpine Gilroy Cogen, L.P., Calpine Gilroy 1, Inc., Calpine King City Cogen, LLC, Calpine Securities Company, L.P. (a parent 
company of Calpine King City Cogen, LLC), Calpine King City, LLC (an indirect parent company of Calpine Securities Company, 
L.P.), Russell City Energy Company, LLC and OMEC. The financial information provided below represents the assets and liabilities 
for one of the special purpose subsidiaries as reflected on our Consolidated Balance Sheets and is provided below as required 
pursuant to certain applicable agreements. These amounts may differ materially from the assets and liabilities for these entities 
that present individual financial statements on a stand-alone basis to their project lenders.

GEC, a wholly-owned subsidiary of GEC Holdings, LLC, has been established as an entity with its existence separate 
from us and other subsidiaries of ours. On March 2, 2012, we closed on the purchase of two of the three third party interests in 
GEC Holdings, LLC pursuant to the purchase agreements that were executed in December 2011. The following table sets forth 
selected financial information of GEC at December 31, 2012 (in millions):

RISK MANAGEMENT AND COMMODITY ACCOUNTING

Our commercial hedging and optimization strategies are designed to maximize our risk-adjusted Commodity Margin by 
leveraging our knowledge, experience and fundamental views on natural gas and power. We actively manage our risk exposures 
with  a  variety  of  physical  and  financial  instruments  with  varying  time  horizons.  These  instruments  include  PPAs,  tolling 
arrangements, Heat Rate swaps and options, load sales, steam sales, buying and selling standard physical products, buying and 
selling exchange traded instruments, gas transportation and storage arrangements, electric transmission service and other contracts 
for the sale and purchase of power products.

We conduct our hedging and optimization activities within a structured risk management framework based on controls, 
policies and procedures. We monitor these activities through active and ongoing management and oversight, defined roles and 
responsibilities,  and  daily  risk  measurement  and  reporting.  Additionally,  we  seek  to  manage  the  associated  risks  through 
diversification, by controlling position sizes, by using portfolio position limits, and by entering into offsetting positions that lock 
in a margin. We also are exposed to commodity price movements (both profits and losses) in connection with these transactions. 
These positions are included in and subject to our consolidated risk management portfolio position limits and controls structure. 
Changes in fair value of commodity positions that do not qualify for or we do not elect either hedge accounting or the normal 
purchase normal sale exemption are recognized currently in earnings and are separately stated on our Consolidated Statements of 
Operations in unrealized mark-to-market gain/loss as a component of operating revenues (for power contracts and Heat Rate swaps 
and options) and fuel and purchased energy expense (for natural gas contracts, swaps and options). Our future hedged status and 
marketing and optimization activities are subject to change as determined by our commercial operations group, Chief Risk Officer, 
senior management and Board of Directors.

In order to simplify our reporting, we elected to discontinue the application of hedge accounting treatment during the 
first quarter of 2012 for all commodity derivatives, including the remaining commodity derivatives previously accounted for as 
cash flow hedges. Accordingly, prospective changes in fair value from the date of this election are reflected in unrealized mark-
to-market activity on our Consolidated Statements of Operations and could create more volatility in our earnings. The fair value 
of our commodity derivative instruments residing in AOCI during the previous application of hedge accounting was reclassified 
to earnings during 2012 as the related economic transactions affected earnings or the forecasted transaction became probable of 
not occurring. 

At any point in time, the relative quantity of our products hedged or sold under longer-term contracts is determined by 
the availability of forward product sales opportunities and our view of the attractiveness of the pricing available for forward sales.  
Historically, we have economically hedged a portion of our expected generation and natural gas portfolio mostly through power 
and  natural  gas  forward  physical  and  financial  transactions;  however,  we  currently  remain  susceptible  to  significant  price 
movements for 2013 and beyond. When we elect to enter into these transactions, we are able to economically hedge a portion of 
our Spark Spread at pre-determined generation and price levels.

We have historically used interest rate swaps to adjust the mix between our fixed and variable rate debt. To the extent 
eligible, our interest rate swaps have been designated as cash flow hedges, and changes in fair value are recorded in OCI to the 
extent they are effective with gains and losses reclassified into earnings in the same period during which the hedged forecasted 
transaction affects earnings. The reclassification of unrealized losses from AOCI into earnings and the changes in fair value and 
settlements subsequent to the reclassification date of the interest rate swaps formerly hedging our First Lien Credit Facility is 
presented separately from interest expense as loss on interest rate derivatives on our Consolidated Statements of Operations. See 
Note 8 of the Notes to Consolidated Financial Statements for further discussion of our derivative instruments.

The primary factors affecting our market risk and the fair value of our derivatives at any point in time are the volume of 
open derivative positions (MMBtu, MWh and $ notional amounts); changing commodity market prices, primarily for power and 
natural gas; our credit standing and that of our counterparties for energy commodity derivatives; and prevailing interest rates for 
our interest rate swaps. Since prices for power and natural gas and interest rates are volatile, there may be material changes in the 
fair value of our derivatives over time, driven both by price volatility and the changes in volume of open derivative transactions. 
Our derivative assets have decreased to approximately $0.4 billion at December 31, 2012, when compared to approximately $1.1 
billion at December 31, 2011, and our derivative liabilities have decreased to approximately $0.6 billion at December 31, 2012, 
when compared to approximately $1.4 billion at December 31, 2011. At December 31, 2012, the fair value of our level 3 derivative 
assets and liabilities represent only a small portion of our total assets and liabilities measured at fair value (approximately 1%). 
See Note 7 of the Notes to Consolidated Financial Statements for further information related to our level 3 derivative assets and 
liabilities.

The change in fair value of our outstanding commodity and interest rate derivative instruments from January 1, 2012, 

through December 31, 2012, is summarized in the table below (in millions):

(1) 

Interest rate settlements consist of recognized losses of $146 million related to interest rate swaps that were terminated 
during 2012, $15 million related to recognition of losses from settlements of designated cash flow hedges and $13 million 
in losses from settlements of undesignated interest rate swaps (represents a portion of interest expense and loss on interest 
rate derivatives as reported on our Consolidated Statements of Operations).

(2)  Gains on settlement of commodity contracts not designated as hedging instruments of $144 million (represents a portion 
of Commodity revenue and Commodity expense as reported on our Consolidated Statements of Operations) and $72 million 
related to recognition of losses from other changes in derivative assets and liabilities not reflected in OCI or earnings, 
partially offset by de-designated cash flow hedges, previously reflected in AOCI.

(3)  Net commodity and interest rate derivative assets and liabilities reported in Notes 7 and 8 of the Notes to Consolidated 

Financial Statements.

The change since the last balance sheet date in the total value of the derivatives (both assets and liabilities) is reflected 
either in cash for option premiums paid or collected, in OCI, net of tax for cash flow hedges, or on our Consolidated Statements 
of Operations as a component (gain or loss) in earnings.

Our change in AOCI from an accumulated loss of $178 million at December 31, 2011, to an accumulated loss of $248 
million at December 31, 2012, was primarily driven by $56 million in losses on interest rate swaps due to a decrease in forward 
LIBOR rates, $3 million in losses related to capitalized realized losses on construction swaps hedging our Los Esteros Project 
Debt  and  Russell  City  Project  Debt,  $38  million  in  gains  reclassified  to  earnings  related  to  the  settlement  of  de-designated 
commodity derivative cash flow hedges, and $1 million in unrealized actuarial losses recorded in 2012, partially offset by $16 
million in losses on settlement of interest rate cash flow hedges reclassified to earnings, and a foreign currency translation gain 
of $3 million related to our Canadian subsidiaries and a $9 million income tax benefit recorded during the year ended December 
31, 2012.

Commodity Price Risk — Commodity price risks result from exposure to changes in spot prices, forward prices, price 
volatilities and correlations between the price of power, steam and natural gas. We manage the commodity price risk and the 
variability in future cash flows from forecasted sales of power and purchases of natural gas of our entire portfolio of generating 
assets and contractual positions by entering into various derivative and non-derivative instruments.

The net fair value of outstanding derivative commodity instruments at December 31, 2012, based on price source and 

the period during which the instruments will mature, are summarized in the table below (in millions):

We measure the energy commodity price risks in our portfolio on a daily basis using a VAR model to estimate the potential 
one-day risk of loss based upon historical experience resulting from market movements in comparison to internally established 
thresholds. Our VAR is calculated for our entire portfolio which is comprised of energy commodity derivatives, expected generation 
and natural gas consumption from our power plants, PPAs, and other physical and financial transactions. The portfolio VAR 
calculation  incorporates  positions  for  the  remaining  portion  of  the  current  calendar  year,  exclusive  of  the  current  month  of 
measurement, plus the following two calendar years. We measure VAR using a variance/covariance approach based on a confidence 
level of 95%, a one-day holding period and actual observed historical correlation. While we believe that our VAR assumptions 
and approximations are reasonable, different assumptions and/or approximations could produce materially different estimates.

The table below presents the high, low and average of our daily VAR for the years ended December 31, 2012 and 2011 

(in millions):

Due to the inherent limitations of statistical measures such as VAR, the VAR calculation may not capture the full extent 
of our commodity price exposure. As a result, actual changes in the value of our energy commodity portfolio could be different 
from the calculated VAR, and could have a material impact on our financial results. In order to evaluate the risks of our portfolio 
on a comprehensive basis and augment our VAR analysis, we also measure the risk of the energy commodity portfolio using 
several analytical methods including sensitivity tests, scenario tests, stress tests, and daily position reports.

During  the  fourth  quarter  of  2012,  we  began  to  experience  diminished  liquidity  in  the  forward  commodity  markets 
resulting  from  a  decrease  in  participation  of  counterparties  in  the  marketplace  with  which  to  transact  our  hedging  activities. 
Although this occurrence of diminished liquidity did not negatively impact our 2012 financial results, should it persist during 2013 
and beyond, it could decrease our ability to hedge our forward commodity price risk and create more volatility in our earnings.

Liquidity Risk — Liquidity risk arises from the general funding requirements needed to manage our activities and assets 
and  liabilities.  Increasing  natural  gas  prices  or  Market  Heat  Rates  can  cause  increased  collateral  requirements.  Our  liquidity 
management framework is intended to maximize liquidity access and minimize funding costs during times of rising prices. See 
further discussion regarding our uses of collateral as they relate to our commodity procurement and risk management activities 
in Note 9 of the Notes to Consolidated Financial Statements.

Credit Risk — Credit risk relates to the risk of loss resulting from nonperformance or non-payment by our counterparties 
related to their contractual obligations with us. Risks surrounding counterparty performance and credit could ultimately impact 
the amount and timing of expected cash flows. We also have credit risk if counterparties are unable to provide collateral or post 
margin. We monitor and manage our credit risk through credit policies that include:

• 

• 

• 

credit approvals;

routine monitoring of counterparties’ credit limits and their overall credit ratings;

limiting our marketing, hedging and optimization activities with high risk counterparties;

•  margin, collateral, or prepayment arrangements; and

• 

payment netting arrangements, or master netting arrangements that allow for the netting of positive and negative 
exposures of various contracts associated with a single counterparty.

We have concentrations of credit risk with a few of our commercial customers, primarily independent electric system 
operators, relating to our sales of power, steam and hedging and optimization activities. We believe that our credit policies and 
portfolio of transactions adequately monitor our credit risk, and currently our counterparties are performing and financially settling 
timely according to their respective agreements. We monitor and manage our total comprehensive credit risk associated with all 
of our contracts and PPAs irrespective of whether they are accounted for as an executory contract, a normal purchase normal sale 
or whether they are marked-to-market and included in our derivative assets and liabilities on our Consolidated Balance Sheets. 
Our counterparty credit quality associated with the net fair value of outstanding derivative commodity instruments is included in 
our derivative assets and liabilities at December 31, 2012, and the period during which the instruments will mature are summarized 
in the table below (in millions):

Interest Rate Risk — We are exposed to interest rate risk related to our variable rate debt. Interest rate risk represents the 
potential loss in earnings arising from adverse changes in market interest rates. Our variable rate financings are indexed to base 
rates, generally LIBOR. The following table summarizes the contract terms as well as the fair values of our debt instruments 
exposed to interest rate risk as of December 31, 2012. All outstanding balances and fair market values are shown gross of applicable

Projection based upon anticipated LIBOR rates.

Our variable rate financings are indexed to base rates, generally LIBOR. Interest rate risk represents the potential loss 
in earnings arising from adverse changes in market interest rates. The fair value of our interest rate swaps are validated based upon 
external quotes. Our interest rate swaps are with counterparties we believe are primarily high quality institutions, and we do not 
believe that our interest rate swaps expose us to any significant credit risk. Holding all other factors constant, we estimate that a 
10% decrease in interest rates would result in a change in the fair value of our interest rate swaps hedging our variable rate debt 
of approximately $(9) million at December 31, 2012.

APPLICATION OF CRITICAL ACCOUNTING POLICIES

The preparation of financial statements in accordance with U.S. GAAP requires management to make certain estimates 
and assumptions which are inherently imprecise and may differ significantly from actual results achieved. We believe the following 
are our more critical accounting policies due to the significance, subjectivity and judgment involved in determining our estimates 
used in preparing our Consolidated Financial Statements. See Note 2 of the Notes to Consolidated Financial Statements for a 
discussion of the application of these and other accounting policies. We evaluate our estimates and assumptions used in preparing 
our  Consolidated  Financial  Statements  on  an  ongoing  basis  utilizing  historic  experience,  anticipated  future  events  or  trends, 
consultation with third party advisors or other methods that involve judgment as determined appropriate under the circumstances. 
The resulting effects of changes in our estimates are recorded in our Consolidated Financial Statements in the period in which the 
facts and circumstances that give rise to the change in estimate become known.

Revenue Recognition

We routinely enter into physical commodity contracts for sales of our generated power to manage risk and capture the 
value inherent in our generation. Determining the proper accounting for our power contracts can require significant judgment and 
impact how we recognize revenue. In addition, we determine whether the contract should be accounted for on a gross or net basis. 
Determining the proper accounting treatment involves the evaluation of quantitative, as well as qualitative factors, to determine 
if the contract should be accounted for as one of the following:

• 

• 

• 

• 

a contract that qualifies as a lease;

a derivative;

a contract that meets the definition of a derivative but is eligible for the normal purchase normal sale exemption; or

a contract that is a physical or executory contract.

Lease Accounting — Revenue from contracts accounted for as operating leases, such as certain tolling agreements, with 
minimum lease rentals which vary over time must be levelized. Generally, we levelize these contract revenues on a straight-line 
basis over the term of the contract.

Executory and Physical Contracts Exempt from Derivative Accounting — We generally recognize revenue from the sale 
of power or host steam thermal energy for sale to our customers for use in industrial or other heating operations, upon transmission 
and delivery to the customer at the contractual price. In addition to revenues from power, host steam revenues and RECs from our 
Geysers Assets related to generation, our operating revenues also include:

• 

• 

• 

power and steam revenue consisting of fixed and variable capacity payments, including capacity payments received 
from PJM capacity auctions which are not related to generation;

other revenues such as RMR Contracts, resource adequacy and certain ancillary service revenues; and

other service revenues.

Capacity  payments,  RMR  Contracts,  RECs,  resource  adequacy  and  other  ancillary  revenues  are  recognized  when 

contractually earned and consist of revenues received from our customers either at the market price or a contract price.

See “ — Accounting for Derivative Instruments” directly below for a discussion of the significant judgments and estimates 
related to accounting for derivative instruments. We apply lease accounting to contracts that meet the definition of a lease and 
accrual accounting treatment to those contracts that are either exempt from derivative accounting or do not meet the definition of 
a derivative instrument.

Gross vs. Net Accounting — We determine whether the financial statement presentation of revenues should be on a gross 
or net basis. Where we act as principal, we record settlement of our physical commodity contracts on a gross or net basis dependent 
upon whether the contract results in physical delivery of the underlying product. With respect to our physical executory contracts, 
where we do not take title to the commodities but receive a variable payment to convert natural gas into power and steam in a 
tolling operation, we record revenues on a net basis.

Fair Value Measurements

We use fair value to measure certain of our assets, liabilities and expenses in our financial statements. Fair value is the 
amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants 
at the measurement date (i.e., the exit price). Generally, the determination of fair value requires the use of significant judgment 
and different approaches and models under varying circumstances. Under a market based approach, we consider prices of similar 
86

 
 
assets, consult with brokers and experts or employ other valuation techniques. Under an income based approach, we generally 
estimate future cash flows and then discount them at a risk adjusted rate.

Accordingly,  the  determination  of  fair  value  represents  a  critical  accounting  policy.  Our  most  significant  fair  value 
measurements represent the valuation of our derivative assets and liabilities, which are measured on a recurring basis (each reporting 
period) and measurements of impairments and acquired assets on a nonrecurring basis. We primarily apply the market approach 
and income approach for recurring fair value measurements (primarily our derivative assets and liabilities) using the best available 
information. We primarily utilize the income approach for nonrecurring fair value measurements such as impairments of our assets 
as market prices for similar assets may not be readily available and may not incorporate the expected future returns from our assets. 
We utilize valuation techniques that seek to maximize the use of observable inputs and minimize the use of unobservable inputs. 
We classify fair value balances based on the observability of those inputs. U.S. GAAP establishes a fair value hierarchy which 
classifies fair value measurements from level 1 through level 3 based upon the inputs used to measure fair value:

Level 1 — Quoted prices (unadjusted) are available in active markets for identical assets or liabilities as of the reporting 
date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide 
pricing information on an ongoing basis.

Level 2 — Pricing inputs include quoted prices for similar assets and liabilities in active markets, and inputs other than 
quoted prices that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial 
instrument.

Level 3 — Pricing inputs include significant inputs that are generally less observable or from unobservable sources. These 

inputs may be used with internally developed methodologies that result in management’s best estimate of fair value.

Derivative Instruments and Valuation Techniques

The primary factors affecting the fair value of our derivative instruments at any point in time are the volume of open 
derivative positions (MMBtu, MWh and $ notional amounts); changing commodity market prices, primarily for power and natural 
gas; our credit standing and that of our counterparties for energy commodity derivatives; and prevailing interest rates for our 
interest rate swaps. Prices for power and natural gas and interest rates are volatile, which can result in material changes in the fair 
value measurements reported in our financial statements in the future. Derivative contracts can be exchange-traded or OTC. For 
OTC derivatives that trade in liquid markets, model inputs can generally be verified and model selection does not involve significant 
management judgment. Certain OTC derivatives trade in less liquid markets with limited pricing information, and the determination 
of fair value for these derivatives is inherently more difficult.

For our level 2 and level 3 derivative instruments, we utilize models to measure fair value. Where models are used, the 
selection of a particular model to value an asset or liability depends upon the contractual terms and specific risks, as well as the 
availability of pricing information in the market. We generally use similar models to value similar instruments. Valuation models 
require a variety of inputs, including contractual terms, market prices, yield curves, credit curves and measures of volatility. These 
models  are  primarily  industry-standard  models,  including  the  Black-Scholes  option-pricing  model.  Substantially  all  of  these 
assumptions are observable in the marketplace throughout the full term of the instrument, can be derived from observable data or 
are supported by observable levels at which transactions are executed in the marketplace. In cases where there is no corroborating 
market information available to support significant model inputs, we initially use the transaction price as the best estimate of fair 
value.

Our derivative instruments that are traded on the NYMEX primarily consist of natural gas swaps, futures and options 

and are classified as level 1 fair value measurements.

Our derivative instruments that primarily consist of interest rate swaps and OTC power and natural gas forwards for 
which market-based pricing inputs are observable are classified as level 2 fair value measurements. Generally, we obtain our 
level 2 pricing inputs from market sources such as the Intercontinental Exchange and Bloomberg.

Our OTC power and natural gas forwards and options where pricing inputs are unobservable, as well as other complex 
and structured transactions are classified as level 3 fair value measurements. Complex or structured transactions are tailored to 
our or our customers’ needs and can introduce the need for internally-developed model inputs which might not be observable in 
or corroborated by the market. When such inputs have a significant impact on the measurement of fair value, the instrument is 
categorized in level 3. At each balance sheet date, we perform an analysis of all instruments subject to fair value measurement 
and include in level 3 all of those whose fair value is based on significant unobservable inputs.

The determination of fair value of our derivatives also includes consideration of our credit standing, the credit standing 
of our counterparties and the impact of credit enhancements, if any. We assess non-performance risk by adjusting the fair value 

87

of our derivatives based on our credit standing or the credit standing of our counterparties involved and the impact of credit 
enhancements, if any. Such valuation adjustments represent the amount of probable loss due to default either by us or a third party. 
Our credit valuation methodology is based on a quantitative approach which allocates a credit adjustment to the fair value of 
derivative transactions based on the net exposure of each counterparty. We develop our credit reserve based on our expectation 
of the market participants’ perspective of potential credit exposure. Our calculation of the credit reserve on net asset positions is 
based on available market information including credit default swap rates, credit ratings and historical default information. We 
also incorporate non-performance risk in net liability positions based on an assessment of our potential risk of default.

Impairments

When we determine an impairment exists, we determine fair value using valuation techniques such as the present value 
of expected future cash flows. In order to estimate future cash flows, we consider historical cash flows, existing and future contracts 
and PPAs and changes in the market environment and other factors that may affect future cash flows. To the extent applicable, the 
assumptions we use are consistent with forecasts that we are otherwise required to make (for example, in preparing our other 
earnings forecasts). The use of this method involves inherent uncertainty. We use our best estimates in making these evaluations 
and consider various factors, including forward price curves for power and fuel costs and forecasted operating costs. However, 
actual future market prices and project costs could vary from the assumptions used in our estimates, and the impact of such 
variations could be material.

We also discount the estimated future cash flows associated with the asset using a single interest rate representative of 
the risk involved with such an investment including contract terms, tenor and credit risk of counterparts. We may also consider 
prices of similar assets, consult with brokers, or employ other valuation techniques. We use our best estimates in making these 
evaluations; however, actual future market prices and project costs could vary from the assumptions used in our estimates, and 
the impact of such variations could be material.

Acquisitions of Assets and Liabilities

U.S.  GAAP  requires  that  the  purchase  price  for  an  acquisition,  such  as  our  Bosque  Energy  Center  and  Conectiv 
Acquisitions, be assigned and allocated to the individual assets and liabilities based upon their fair value. Generally, the amount 
recorded in the financial statements for an acquisition is the purchase price (value of the consideration paid), but a purchase price 
that exceeds the fair value of the assets acquired will result in the recognition of goodwill. In addition to the potential for the 
recognition of goodwill, differing fair values will impact the allocations of the purchase price to the individual assets and liabilities 
and can impact the gross amount and classification of assets and liabilities recorded on our Consolidated Balance Sheet and can 
impact the timing and the amount of depreciation expense recorded in any given period. We utilize our best effort to make our 
determinations and review all information available including estimated future cash flows and prices of similar assets when making 
our best estimate. We also may hire independent appraisers to help us make this determination as we deem appropriate under the 
circumstances.

Accounting for Derivative Instruments

We recognize all derivative instruments that qualify for derivative accounting treatment as either assets or liabilities and 
measure those instruments at fair value unless they qualify for, and we elect, the normal purchase normal sale exemption. For 
transactions in which we elect the normal purchase normal sale exemption, gains and losses are not reflected on our Consolidated 
Statements of Operations until the period of delivery. In order to simplify our reporting, we elected to discontinue the application 
of hedge accounting treatment during the first quarter of 2012 for all commodity derivatives, including the remaining commodity 
derivatives previously accounted for as cash flow hedges. Accordingly, prospective changes in fair value from the date of this 
election are reflected in unrealized mark-to-market gain/loss on our Consolidated Statements of Operations and could create more 
volatility in our earnings. Revenues and fuel costs derived from instruments that qualified for hedge accounting or represent an 
economic hedge are recorded in the same financial statement line item as the item being hedged. Although we have discontinued 
the application of hedge accounting treatment for our commodity derivative instruments, prior to this change and for our interest 
rate swaps, hedge accounting requires us to formally document, designate and assess the effectiveness of transactions that receive 
hedge accounting. We present the cash flows from our derivatives in the same category as the item being hedged (or economically 
hedged) within operating activities or investing activities (in the case of settlements for our interest rate swaps formerly hedging 
our  First  Lien  Credit  Facility  term  loans)  on  our  Consolidated  Statements  of  Cash  Flows  unless  they  contain  an  other-than-
insignificant financing element in which case their cash flows are classified within financing activities.

Hedge Accounting — Revenues and expenses derived from derivative instruments that qualify for hedge accounting are 
recorded  in  the  period  and  same  financial  statement  line  item  as  the  hedged  item.  Hedge  accounting  requires  us  to  formally 
document, designate and assess the effectiveness of transactions that receive hedge accounting. We present the cash flows from 
hedging derivatives in the same category as the item being hedged within operating activities on our Consolidated Statements of 

88

Cash Flows unless they contain an other-than-insignificant financing element in which case their cash flows are classified within 
financing activities.

Cash Flow Hedges — We report the effective portion of the unrealized gain or loss on a derivative instrument designated 
and qualifying as a cash flow hedging instrument as a component of OCI and reclassify such gains and losses into earnings in the 
same period during which the hedged forecasted transaction affects earnings. Gains and losses due to ineffectiveness on commodity 
hedging instruments are recognized currently in earnings and are separately stated on our Consolidated Statements of Operations 
in  unrealized  mark-to-market  gain/loss  as  a  component  of  operating  revenues  (for  power  contracts  and  swaps)  and  fuel  and 
purchased energy expense (for natural gas contracts and swaps). Gains and losses due to ineffectiveness on interest rate  hedging 
instruments are recognized currently in earnings as a component of interest expense (for interest rate swaps except as discussed 
below).  If  it  is  determined  that  the  forecasted  transaction  is  no  longer  probable  of  occurring,  then  hedge  accounting  will  be 
discontinued prospectively and future changes in fair value are recorded in earnings. If the hedging instrument is terminated or 
de-designated prior to the occurrence of the hedged forecasted transaction, the net accumulated gain or loss associated with the 
changes in fair value of the hedge instrument remains deferred in AOCI until such time as the forecasted transaction impacts 
earnings or until it is determined that the forecasted transaction is probable of not occurring. 

Derivatives Not Designated as Hedging Instruments — We enter into power, natural gas and interest rate transactions 
that primarily act as economic hedges to our asset and interest rate portfolio, but either do not qualify as hedges under the hedge 
accounting guidelines or qualify under the hedge accounting guidelines and the hedge accounting designation has not been elected. 
Changes in fair value of commodity derivatives not designated as hedging instruments are recognized currently in earnings and 
are separately stated on our Consolidated Statements of Operations in unrealized mark-to-market gain/loss as a component of 
operating revenues (for power contracts and Heat Rate swaps and options) and fuel and purchased energy expense (for natural 
gas contracts, swaps and options). Changes in fair value of interest rate derivatives not designated as hedging instruments are 
recognized currently in earnings as interest expense (for interest rate swaps except as discussed below).

Interest Rate Swaps Formerly Hedging our First Lien Credit Facility and Other Project Debt — During 2010, we repaid 
approximately $3.5 billion of our First Lien Credit Facility term loans, which had approximately $3.3 billion notional amount of 
interest rate swaps hedging the scheduled variable interest payments, and in January 2011, we repaid the remaining approximately 
$1.2 billion of First Lien Credit Facility term loans which had approximately $1.0 billion notional amount of interest rate swaps 
hedging the scheduled variable interest payments. With the repayment of the remaining First Lien Credit Facility term loans, 
unrealized losses of approximately $91 million in AOCI related to the interest rate swaps formerly hedging the First Lien Credit 
Facility, were reclassified out of AOCI and into earnings as an additional loss on interest rate derivatives during 2011. In addition, 
we reclassified approximately $17 million in unrealized losses in AOCI to loss on interest rate derivatives during 2011 resulting 
from the repayment of project debt in 2011. During 2010, we reclassified approximately $206 million out of AOCI and into earnings 
as additional loss on interest rate derivatives related to interest rate swaps formerly hedging our First Lien Credit Facility term 
loans. We have presented the reclassification of unrealized losses from AOCI into earnings and the changes in fair value and 
settlements subsequent to the reclassification date of the interest rate swaps formerly hedging our First Lien Credit Facility described 
above separate from interest expense as loss on interest rate derivatives on our Consolidated Statements of Operations. On March 
26, 2012, we terminated the legacy interest rate swaps formerly hedging our First Lien Credit Facility and paid the fair value of 
the swaps totaling approximately $156 million. Approximately $14 million of the settlement amount was recorded as a component 
of  loss  on  interest  rate  derivatives  on  our  Consolidated  Statement  of  Operations  for  the  year  ended  December 31,  2012,  and 
approximately $142 million reflected the realization of losses recorded in prior periods.

See Notes 7 and 8 of the Notes to Consolidated Financial Statements for further discussion of our derivative instruments 

and our interest rate swaps formerly hedging our First Lien Credit Facility term loans.

Accounting for VIEs and Financial Statement Consolidation Criteria

We consolidate all VIEs where we determined that we have both the power to direct the activities of a VIE that most 
significantly impact the VIE's economic performance and the obligation to absorb losses or receive benefits from the VIE. We 
have determined that we hold the obligation to absorb losses and receive benefits in all of our VIEs where we hold the majority 
equity interest. Therefore, our determination of whether to consolidate is based upon which variable interest holder has the power 
to direct the most significant activities of the VIE (the primary beneficiary). Our analysis includes consideration of the following 
primary  activities  which  we  believe  to  have  a  significant  impact  on  a  power  plant's  financial  performance:  operations  and 
maintenance, plant dispatch, and fuel strategy as well as our ability to control or influence contracting and overall plant strategy. 
Our approach to determining which entity holds the powers and rights is based on powers held as of the balance sheet date. 
Contractual terms that may change the powers held in future periods, such as a purchase or sale option, are not considered in our 
analysis. Based on our analysis, we believe that we hold the power and rights to direct the most significant activities of all our 
majority owned VIEs.

89

Under our consolidation policy and under U.S. GAAP we also:

• 

• 

perform an ongoing reassessment each reporting period of whether we are the primary beneficiary of our VIEs; and

evaluate  if  an  entity  is  a  VIE  and  whether  we  are  the  primary  beneficiary  whenever  any  changes  in  facts  and 
circumstances occur such that the holders of the equity investment at risk, as a group, lose the power from voting 
rights or similar rights of those investments to direct the activities of a VIE that most significantly impact the VIE's 
economic performance or when there are other changes in the powers held by individual variable interest holders.

Because we are required to perform ongoing reassessments of whether we are the primary beneficiary, future changes 
in our assessments of whether we are the primary beneficiary could require us to consolidate our VIEs that are currently not 
consolidated or deconsolidate our VIEs that are currently consolidated based upon our reassessments in future periods. Making 
these determinations can require the use of significant judgment to determine which variable interest holder has the power to direct 
the most significant activities of the VIE (the primary beneficiary) and can directly impact amounts reported on our Consolidated 
Financial Statements.

Disclosure Requirements

U.S. GAAP requires separate disclosure on the face of our Consolidated Balance Sheets of the significant assets of a 
consolidated VIE that can be used only to settle obligations of the consolidated VIE and the significant liabilities of a consolidated 
VIE for which creditors (or beneficial interest holders) do not have recourse to the general credit of the primary beneficiary. In 
determining which assets of our VIEs meet the separate disclosure criteria, we consider that this separate disclosure requirement 
is met where Calpine Corporation is substantially limited or prohibited from access to assets (primarily cash and cash equivalents, 
restricted cash and property, plant and equipment), and where our VIEs had project financing that prohibits the VIE from providing 
guarantees on the debt of others. In determining which liabilities of our VIEs meet the separate disclosure criteria, we consider 
that this separate disclosure requirement is met where there are agreements that prohibit the debt holders of the VIEs from recourse 
to the general credit of Calpine Corporation and where the amounts were material to our financial statements.

Unconsolidated VIEs

We have a 50% partnership interest in Greenfield LP and in Whitby. Greenfield LP and Whitby are also VIEs; however, 
we do not have the power to direct the most significant activities of these entities and therefore do not consolidate them. We account 
for these entities under the equity method of accounting and include our net equity interest in investments on our Consolidated 
Balance Sheets. Our equity interest in the net income from Greenfield LP and Whitby for the years ended December 31, 2012, 
2011 and 2010, are recorded in (income) from unconsolidated investments in power plants.

We hold a call option to purchase the Inland Empire Energy Center (a 775 MW natural gas-fired power plant located in 
California which achieved COD on May 3, 2010) from GE that may be exercised between years 2017 and 2024. GE holds a put 
option whereby they can require us to purchase the power plant, if certain plant performance criteria are met by 2025. We determined 
that we are not the primary beneficiary of the Inland Empire power plant, and we do not consolidate it due to the fact that GE 
directs the most significant activities of the power plant including operations and maintenance.

Long-Lived Assets and Depreciation Expense

Determination  of  the  appropriate  depreciation  method,  proper  useful  lives  and  salvage  values  involves  significant 
judgment, estimates, assumptions and historical experience. Changes in our estimates and methods can result in a significant 
impact in the amounts and timing of when we recognize depreciation expense and therefore significantly impact our financial 
condition and results of operations from period to period. Different depreciation methods can impact the timing and amount of 
depreciation expense affecting our results of operations and could result in different net book values of assets at a particular time 
during the useful life of the asset affecting our financial position. Estimates of useful lives also significantly impact the timing 
and amounts of depreciation expense and include significant estimates. If useful lives are too short, then the asset is depreciated 
too quickly and depreciation expense is overstated. Estimated useful lives can significantly decrease if routine maintenance or 
certain upgrades are not performed, premature mechanical failure of the asset occurs, significant increases in the planned level of 
usage occur, advances in technology make the asset obsolete, or if there are adverse changes in environmental regulations. Our 
depreciable cost basis of our assets are reduced by their estimated salvage values. Estimates involved with salvage values include 
future estimated costs of dismantlement and repair, market prices, environmental regulations and technological advancements. 
Dependent upon our ability to accurately estimate salvage values and the timing of disposal, the salvage values actually realized 
for our assets could significantly increase or decrease resulting in additional gains or losses in the year of disposal.

We depreciate our assets under the straight-line method over the shorter of their estimated useful lives or lease term. For 
our natural gas-fired power plants, we assume an estimated salvage value which approximates 10% of the depreciable cost basis 

90

where we own the land or have a favorable option to purchase the land at conclusion of the lease term and approximately 0.15% 
of the depreciable costs basis for rotable equipment. For our Geysers Assets, we typically assume no salvage values. We use the 
component depreciation method for our natural gas-fired power plant rotable parts and our information technology equipment and 
the composite depreciation method for most of all of the other natural gas-fired power plant asset groups and Geysers Assets.

Impairment Evaluation of Long-Lived Assets (Including Intangibles and Investments)

We evaluate our long-lived assets, such as property, plant and equipment, equity method investments, turbine equipment 
and specifically identified intangibles, on an annual basis or when events or changes in circumstances indicate that the carrying 
value of such assets may not be recoverable. Examples of such events or changes in circumstances are:

• 

• 

• 

• 

• 

• 

a significant decrease in the market price of a long-lived asset;

a significant adverse change in the manner an asset is being used or its physical condition;

an adverse action by a regulator or legislature or an adverse change in the business climate;

an accumulation of costs significantly in excess of the amount originally expected for the construction or acquisition 
of an asset;

a current-period loss combined with a history of losses or the projection of future losses; or

a change in our intent about an asset from an intent to hold to a greater than 50% likelihood that an asset will be sold 
or disposed of before the end of its previously estimated useful life.

When we believe an impairment condition on long-lived assets such as PP&E and turbine equipment may have occurred, 
we are required to estimate the undiscounted future cash flows associated with a long-lived asset or group of long-lived assets at 
the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities for long-
lived assets that are expected to be held and used. If we determine that the undiscounted cash flows from an asset to be held and 
used are less than the carrying amount of the asset, or if we have classified an asset as held for sale, we must estimate fair value 
to determine the amount of any impairment loss. Equipment assigned to each power plant is not evaluated for impairment separately; 
instead, we evaluate our operating power plants and related equipment as a whole unit. When we believe an impairment condition 
may exist on specifically identifiable intangibles or an investment, we must estimate their fair value to determine the amount of 
any impairment loss. Significant judgment is required in determining fair value as discussed above in “— Fair Value Measurements.” 

All construction and development projects are reviewed for impairment whenever there is an indication of potential 
reduction in fair value. If it is determined that it is no longer probable that the projects will be completed and all capitalized costs 
recovered through future operations, the carrying values of the projects would be written down to their fair value. When we 
determine that our assets meet the assets held-for-sale criteria, they are reported at the lower of the carrying amount or fair value 
less the cost to sell. We are also required to evaluate our equity method investments to determine whether or not they are impaired 
when the value is considered an “other than a temporary” decline in value.

See Note 2 of the Notes to Consolidated Financial Statements for further discussion of our impairment evaluation of 

long-lived assets.

Accounting for Income Taxes

To arrive at our consolidated income tax provision and other tax balances, significant judgment and estimates are required. 
Although we believe that our estimates are reasonable, no assurance can be given that the final tax outcome of these matters will 
not be different than that which is reflected in our historical tax provisions and accruals. Such differences could have a material 
impact on our income tax provision, other tax accounts and net income in the period in which such determination is made.

For federal income tax reporting purposes, our historical tax reporting group was comprised primarily of two separate 
groups, CCFC and its subsidiaries, which we referred to as the CCFC group, and Calpine Corporation and its subsidiaries other 
than CCFC, which we referred to as the Calpine group. During the first quarter of 2011, we elected to consolidate our CCFC and 
Calpine groups for federal income tax reporting purposes and Calpine filed a consolidated federal income tax return for the year 
ended December 31, 2011 that included the CCFC group. As a result of the consolidation, the CCFC group deferred tax liabilities 
will be eligible to offset existing Calpine group NOLs that were reserved by a valuation allowance. Accordingly, we recorded a 
one-time federal deferred income tax benefit of approximately $76 million during the first quarter of 2011 to reduce our valuation 
allowance. For the year ended December 31, 2010, the CCFC group was deconsolidated from the Calpine group for federal income 
tax reporting purposes. See Note 10 of the Notes to Consolidated Financial Statements for additional discussion of our Calpine 
and CCFC groups.

91

Our NOL carryforwards consist primarily of federal NOL carryforwards of approximately $7.3 billion, which expire 
between 2023 and 2031, and NOL carryforwards in 33 states and the District of Columbia totaling approximately $4.0 billion, 
which  expire  between  2013  and  2031,  substantially  all  of  which  are  offset  with  a  full  valuation  allowance.  We  also  have 
approximately  $1.0  billion  in  foreign  NOLs,  substantially  all  of  which  are  offset  with  a  full  valuation  allowance. The  NOL 
carryforwards available are subject to limitations on their annual usage. Under federal and applicable state income tax laws, a 
corporation is generally permitted to deduct from taxable income in any year NOLs carried forward from prior years subject to 
certain time limitations as prescribed by the taxing authorities. Under federal income tax law, our NOL carryforwards can be 
utilized to reduce future taxable income subject to certain limitations, including if we were to undergo an ownership change as 
defined by Section 382 of the IRC. We experienced an ownership change on the Effective Date as a result of the cancellation of 
our old common stock and the distribution of our new common stock pursuant to our Plan of Reorganization. However, this 
ownership change and the resulting annual limitations are not expected to result in the expiration of our NOL carryforwards if we 
are able to generate sufficient future taxable income within the carryforward periods. At December 31, 2012, approximately $2.4 
billion of our $7.3 billion federal NOLs are not subject to annual Section 382 limitations. When considering our cumulative annual 
Section  382  limitations,  in  addition  to  our  post-Effective  Date  NOLs  that  are  not  limited,  our  total  unrestricted  NOLs  are 
approximately $7.1 billion. If a subsequent ownership change were to occur as a result of future transactions in our common stock, 
accompanied by a significant reduction in our market value immediately prior to the ownership change, our ability to utilize the 
NOL carryforwards may be significantly limited. 

Deferred tax assets relating to tax benefits of employee stock-based compensation do not reflect stock options exercised 
and restricted stock that vested in 2012. Some stock option exercises and restricted stock vestings result in tax deductions in excess 
of previously recorded deferred tax benefits based on the equity award value at the grant date. Although these additional tax 
benefits or “windfalls” are reflected in net operating tax carryforwards pursuant to accounting for stock-based compensation under 
U.S. GAAP, the additional tax benefit associated with the windfall is not recognized until the deduction reduces taxes payable, 
which will not occur for Calpine until a future period. Accordingly, since the tax benefit does not reduce our current taxes payable 
in 2012 due to NOL carryforwards, these “windfall” tax benefits are not reflected in our NOL in deferred tax assets for 2012. 
Windfalls included in NOL carryforwards, but not reflected in deferred tax assets as of December 31, 2012 were $10 million. 

Under state income tax laws, our NOL carryforwards can be utilized to reduce future taxable income subject to certain 
limitations, including if we were to undergo an ownership change as defined by Section 382 of the IRC. During 2011, we analyzed 
the effect of our change in ownership on the Effective Date for each of our significant states to determine the amount of our NOL 
limitation. The analysis determined that $640 million of our state NOLs are expected to expire unutilized as a result of statutory 
limitations on the use of some of our pre-emergence date NOLs as of the Effective Date or the cessation of business operations 
in various tax jurisdictions. We reduced our deferred tax asset for state NOLs that we are unable to utilize and made an equal 
reduction in our valuation allowance in 2011. The result did not have an impact on our income tax expense in 2011. We estimate 
that approximately $117 million of our state NOLs expired unutilized during 2012 as a result of statutory state limitations relating 
to the time period NOLs can be carried forward, and accordingly, we reduced our deferred tax asset and made an equal reduction 
in our valuation allowance. The reduction did not have an impact to our income tax expense in 2012. We will likely make future 
annual adjustments to our state NOLs that have expired or are limited under Section 382 of the IRC.

In  the  ordinary  course  of  business,  there  are  many  transactions  and  calculations  where  the  ultimate  tax  outcome  is 
uncertain. Some of these uncertainties arise as a consequence of the treatment of capital assets, financing transactions, multistate 
taxation of operations and segregation of foreign and domestic income and expense to avoid double taxation. We recognize the 
financial statement effects of a tax position when it is more likely than not, based on the technical merits, that the position will be 
sustained upon examination. A tax position that meets the more-likely-than-not recognition threshold is measured as the largest 
amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority. We reverse 
a previously recognized tax position in the first period in which it is no longer more likely than not that the tax position would be 
sustained upon examination. The determination and calculation of uncertain tax positions involves significant judgment in the 
application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with our expectations could have a 
material impact on our financial condition or results of operations. As of December 31, 2012, we had $92 million of unrecognized 
tax benefits from uncertain tax positions.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as 
defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Our internal control over financial reporting is a process 
designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements 
for external purposes in accordance with U.S. GAAP.

Our internal control over financial reporting includes those policies and procedures that:

• 

• 

• 

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of our assets;

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements 
in accordance with U.S. GAAP, and that our receipts and expenditures are being made only in accordance with 
authorizations of our management and directors; and

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition 
of our assets that could have a material effect on our financial statements.

Management has assessed the effectiveness of our internal control over financial reporting as of December 31, 2012. In 
making  its  assessment  of  internal  control  over  financial  reporting,  management  used  the  criteria  described  in  Internal 
Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Based on management’s assessment, management has concluded that our internal control over financial reporting was 
effective as of December 31, 2012 to provide reasonable assurance regarding the reliability of financial reporting and the preparation 
of consolidated financial statements for external reporting purposes in accordance with U.S. GAAP.

Report of Independent Registered Public Accounting Firm

To the Board of Directors
and Stockholders of Calpine Corporation

In our opinion, the consolidated financial statements listed in the index appearing under Item 15(a)-1 present fairly, in all material 
respects, the financial position of Calpine Corporation and its subsidiaries at December 31, 2012 and 2011, and the results of their 
operations and their cash flows for each of the three years in the period ended December 31, 2012 in conformity with accounting 
principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed 
in the index appearing under Item 15(a)-2 presents fairly, in all material respects, the information set forth therein when read in 
conjunction  with  the  related  consolidated  financial  statements. Also  in  our  opinion,  the  Company  maintained,  in  all  material 
respects, effective internal control over financial reporting as of December 31, 2012 based on criteria established in Internal 
Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). 
The  Company’s  management  is  responsible  for  these  financial  statements  and  financial  statement  schedule,  for  maintaining 
effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial 
reporting,  included  in  Management’s  Report  on  Internal  Control  over  Financial  Reporting,  appearing  under  Item  9A.  Our 
responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company’s 
internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards 
of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits 
to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective 
internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included 
examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting 
principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our 
audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, 
assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal 
control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the 
circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability 
of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted 
accounting principles.  A company’s internal control over financial reporting includes those policies and procedures that (i) pertain 
to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets 
of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial 
statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are 
being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that 
could have a material effect on the financial statements.

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because 
of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
For the Years Ended December 31, 2012, 2011 and 2010

1. 

Organization and Operations

We are a wholesale power generation company engaged in the ownership and operation of primarily natural gas-fired 
and geothermal power plants in North America. We have a significant presence in major competitive wholesale power markets in 
California, Texas and the Mid-Atlantic region of the U.S. We sell wholesale power, steam, capacity, renewable energy credits and 
ancillary  services  to  our  customers,  which  include  utilities,  independent  electric  system  operators,  industrial  and  agricultural 
companies, retail power providers, municipalities, power marketers and others. We engage in the purchase of natural gas and fuel 
oil as fuel for our power plants and in related natural gas transportation and storage transactions, and in the purchase of electric 
transmission rights to deliver power to our customers. We also enter into natural gas and power physical and financial contracts 
to economically hedge our business risks and optimize our portfolio of power plants.

2. 

Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

Our Consolidated Financial Statements have been prepared in accordance with U.S. GAAP and include the accounts of 
all  majority-owned  subsidiaries  that  are  not  VIEs  and  all  VIEs  where  we  have  determined  we  are  the  primary  beneficiary. 
Intercompany transactions have been eliminated in consolidation.

Equity Method Investments — We use the equity method of accounting to record our net interests in VIEs where we have 
determined that we are not the primary beneficiary, which include Greenfield LP, a 50% partnership interest, and Whitby, a 50% 
partnership interest. Our share of net income (loss) is calculated according to our equity ownership percentage or according to the 
terms of the applicable partnership agreement. See Note 5 for further discussion of our VIEs and unconsolidated investments.

Change in Presentation — We have changed the presentation on our Consolidated Statements of Operations to separately 
present our Commodity revenue, unrealized mark-to-market gain (loss) and other revenue which are components of operating 
revenues and our Commodity expense and unrealized mark-to-market (gain) loss which are components of fuel and purchased 
energy expense. The change in presentation had no impact on our financial condition, results of operations or cash flows.

Reclassification — We have reclassified RGGI compliance and other environmental costs previously recorded in other 
operating expenses of $10 million and $9 million to Commodity expense on our Consolidated Statements of Operations for the  
years ended December 31, 2011 and 2010, respectively, to conform to the current year presentation.    

Jointly-Owned Plants — Certain of our subsidiaries own undivided interests in jointly-owned plants. These plants are 
maintained and operated pursuant to their joint ownership participation and operating agreements. We are responsible for our 
subsidiaries’ share of operating costs and direct expenses and include our proportionate share of the facilities and related revenues 
and  direct  expenses  in  these  jointly-owned  plants  in  the  corresponding  balance  sheet  and  income  statement  captions  of  our 
Consolidated Financial Statements. The following table summarizes our proportionate ownership interest in jointly-owned power 
plants:

Use of Estimates in Preparation of Financial Statements

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and 
assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures included in our 
Consolidated Financial Statements. Actual results could differ from those estimates.

116

Fair Value of Financial Instruments and Derivatives

The  carrying  values  of  accounts  receivable,  accounts  payable  and  other  receivables  and  payables  approximate  their 
respective fair values due to their short-term maturities. See Note 6 for disclosures regarding the fair value of our debt instruments 
and Notes 7 and 8 for disclosures regarding the fair values of our derivative instruments and margin deposits and certain of our 
cash balances.

Concentrations of Credit Risk

Financial instruments that potentially subject us to credit risk consist of cash and cash equivalents, restricted cash, accounts 
and notes receivable and derivative assets. Certain of our cash and cash equivalents, as well as our restricted cash balances, are 
invested in money market accounts with investment banks that are not FDIC insured. We place our cash and cash equivalents and 
restricted cash in what we believe to be creditworthy financial institutions and certain of our money market accounts invest in 
U.S. Treasury  securities  or  other  obligations  issued  or  guaranteed  by  the  U.S.  Government,  its  agencies  or  instrumentalities. 
Additionally,  we  actively  monitor  the  credit  risk  of  our  counterparties,  including  our  receivable,  commodity  and  derivative 
transactions. Our accounts and notes receivable are concentrated within entities engaged in the energy industry, mainly within the 
U.S. We generally have not collected collateral for accounts receivable from utilities and end-user customers; however, we may 
require collateral in the future. For financial and commodity derivative counterparties, we evaluate the net accounts receivable, 
accounts payable and fair value of commodity contracts and may require security deposits, cash margin or letters of credit to be 
posted if our exposure reaches a certain level or their credit rating declines.

Our counterparties primarily consist of three categories of entities who participate in the wholesale energy markets:

• 

• 

• 

financial institutions and trading companies;

regulated utilities, municipalities, cooperatives, ISOs and other retail power suppliers; and

oil, natural gas, chemical and other energy-related industrial companies.

We have concentrations of credit risk with a few of our commercial customers relating to our sales of power, steam and 
hedging  and  optimization  activities.  We  have  exposure  to  trends  within  the  energy  industry,  including  declines  in  the 
creditworthiness  of  our  counterparties  for  our  commodity  and  derivative  transactions.  Currently,  certain  of  our  marketing 
counterparties within the energy industry have below investment grade credit ratings. Our risk control group manages counterparty 
credit risk and monitors our net exposure with each counterparty on a daily basis. The analysis is performed on a mark-to-market 
basis using forward curves. The net exposure is compared against a counterparty credit risk threshold which is determined based 
on each counterparty’s credit rating and evaluation of their financial statements. We utilize these thresholds to determine the need 
for additional collateral or restriction of activity with the counterparty. We believe that our credit policies and portfolio of transactions 
adequately monitor and diversify our credit risk, and currently our counterparties are performing and financially settling timely 
according to their respective agreements. 

Cash and Cash Equivalents

We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents. We 
have certain project finance facilities and lease agreements that require us to establish and maintain segregated cash accounts, 
which have been pledged as security in favor of the lenders under such project finance facilities, and the use of certain cash balances 
on deposit in such accounts is limited, at least temporarily, to the operations of the respective projects. At December 31, 2012 and 
2011, we had cash and cash equivalents of $131 million and $306 million, respectively, that were subject to such project finance 
facilities and lease agreements.

Restricted Cash

Certain of our debt agreements, lease agreements or other operating agreements require us to establish and maintain 
segregated cash accounts, the use of which is restricted. These amounts are held by depository banks in order to comply with the 
contractual provisions requiring reserves for payments such as for debt service, rent, major maintenance and debt repurchases or 
with applicable regulatory requirements. Funds that can be used to satisfy obligations due during the next 12 months are classified 
as current restricted cash, with the remainder classified as non-current restricted cash. Restricted cash is generally invested in 
accounts earning market rates; therefore, the carrying value approximates fair value. Such cash is excluded from cash and cash 
equivalents on our Consolidated Balance Sheets and Statements of Cash Flows.

(1)  At both December 31, 2012 and 2011, amounts restricted for debt service included approximately $25 million of repurchase 

agreements with a financial institution containing maturity dates greater than one year.

Accounts Receivable and Payable

Accounts receivable and payable represent amounts due from customers and owed to vendors, respectively. Accounts 
receivable are recorded at invoiced amounts, net of reserves and allowances, and do not bear interest. Receivable balances greater 
than 30 days past due are individually reviewed for collectability, and if deemed uncollectible, are charged off against the allowance 
accounts after all means of collection have been exhausted and the potential for recovery is considered remote. We use our best 
estimate to determine the required allowance for doubtful accounts based on a variety of factors, including the length of time 
receivables are past due, economic trends and conditions affecting our customer base, significant one-time events and historical 
write-off experience. Specific provisions are recorded for individual receivables when we become aware of a customer’s inability 
to meet its financial obligations. We review the adequacy of our reserves and allowances quarterly.

The accounts receivable and payable balances also include settled but unpaid amounts relating to our marketing, hedging 
and optimization activities. Some of these receivables and payables with individual counterparties are subject to master netting 
arrangements whereby we legally have a right of offset and settle the balances net. However, for balance sheet presentation purposes 
and to be consistent with the way we present the majority of amounts related to marketing, hedging and optimization activities 
on our Consolidated Statements of Operations, we present our receivables and payables on a gross basis. We do not have any 
significant off balance sheet credit exposure related to our customers.

Inventory

At December 31, 2012 and 2011, we had inventory of $301 million and $294 million, respectively. Inventory primarily 
consists of spare parts, stored natural gas and fuel oil, emission reduction credits and natural gas exchange imbalances. Inventory, 
other than spare parts, is stated primarily at the lower of cost or market value under the weighted average cost method. Spare parts 
inventory is valued at weighted average cost and is expensed to plant operating expense or capitalized to property, plant and 
equipment as the parts are utilized and consumed.

Collateral

We use margin deposits, prepayments and letters of credit as credit support with and from our counterparties for commodity 
procurement and risk management activities. In addition, we have granted additional first priority liens on the assets previously  
subject to first priority liens under our First Lien Notes, First Lien Term Loans and Corporate Revolving Facility as collateral 
under certain of our power and natural gas agreements. These agreements qualify as “eligible commodity hedge agreements” 
under our First Lien Notes, First Lien Term Loans and Corporate Revolving Facility. The first priority liens have been granted in 
order to reduce the cash collateral and letters of credit that we would otherwise be required to provide to our counterparties under 
such agreements. The counterparties under such agreements would share the benefits of the collateral subject to such first priority 
liens ratably with the lenders under our First Lien Notes, First Lien Term Loans and Corporate Revolving Facility. Our interest 
rate swap agreements relate to hedges of certain of our project financings collateralized by first priority liens on the underlying 
assets. See Note 9 for a further discussion on our amounts and use of collateral.

Deferred Financing Costs

Costs incurred related to the issuance of debt instruments are deferred and amortized over the term of the related debt 
using  a  method  that  approximates  the  effective  interest  rate  method.  However,  when  the  timing  of  debt  transactions  involve 
contemporaneous exchanges of cash between us and the same creditor(s) in connection with the issuance of a new debt obligation 

118

 
 
 
and satisfaction of an existing debt obligation, deferred financing costs are accounted for depending on whether the transaction 
qualifies as an extinguishment or modification, which requires us to either write off the original deferred financing costs and 
capitalize the new issuance costs, or continue to amortize the original deferred financing costs and immediately expense the new 
issuance costs.

Property, Plant and Equipment, Net

Property, plant, and equipment items are recorded at cost. We capitalize costs incurred in connection with the construction 
of power plants, the development of geothermal properties and the refurbishment of major turbine generator equipment. When 
capital improvements to leased power plants meet our capitalization criteria they are capitalized as leasehold improvements and 
amortized over the shorter of the term of the lease or the economic life of the capital improvement. We expense maintenance when 
the service is performed for work that does not meet our capitalization criteria. Our current capital expenditures at our Geysers 
Assets are those incurred for proven reserves and reservoir replenishment (primarily water injection), pipeline and power generation 
assets and drilling of “development wells” as all drilling activity has been performed within the known boundaries of the steam 
reservoir.  We  have  capitalized  costs  incurred  during  ownership  consisting  of  additions,  repairs  or  replacements  when  they 
appreciably extend the life, increase the capacity or improve the efficiency or safety of the property. Such costs are expensed when 
they do not meet the above criteria. We purchased our Geysers Assets as a proven steam reservoir and accounted for the assets 
under purchase accounting. All well costs, except well workovers and routine repairs and maintenance, have been capitalized since 
our purchase date.

We depreciate our assets under the straight-line method over the shorter of their estimated useful lives or lease term. For 
our natural gas-fired power plants, we assume an estimated salvage value which approximates 10% of the depreciable cost basis 
where we own the land or have a favorable option to purchase the land at conclusion of the lease term and approximately 0.15% 
of the depreciable costs basis for rotable equipment. For our Geysers Assets, we typically assume no salvage values. We use the 
component depreciation method for our natural gas-fired power plant rotable parts and our information technology equipment and 
the composite depreciation method for most of all of the other natural gas-fired power plant asset groups and Geysers Assets.

Generally, upon normal retirement of assets under the composite depreciation method, the costs of such assets are retired 
against accumulated depreciation and no gain or loss is recorded. For the retirement of assets under the component depreciation 
method, generally, the costs and related accumulated depreciation of such assets are removed from our Consolidated Balance 
Sheets and a gain or loss is recorded as plant operating expense.

Impairment Evaluation of Long-Lived Assets (Including Intangibles and Investments)

We evaluate our long-lived assets, such as property, plant and equipment, equity method investments and definite-lived 
intangible assets for impairment, when events or changes in circumstances indicate that the carrying value of such assets may not 
be recoverable. Equipment assigned to each power plant is not evaluated for impairment separately; instead, we evaluate our 
operating power plants and related equipment as a whole unit. When we believe an impairment condition may have occurred, we 
are required to estimate the undiscounted future cash flows associated with a long-lived asset or group of long-lived assets at the 
lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities for long-
lived assets that are expected to be held and used. If we determine that the undiscounted cash flows from an asset to be held and 
used are less than the carrying amount of the asset, or if we have classified an asset as held for sale, we must estimate fair value 
to determine the amount of any impairment loss. All construction and development projects are reviewed for impairment whenever 
there is an indication of potential reduction in fair value. If it is determined that a construction or development project is no longer 
probable of completion and the capitalized costs will not be recovered through future operations, the carrying value of the project 
will be written down to its fair value.

In order to estimate future cash flows, we consider historical cash flows, existing and future contracts and PPAs and 
changes in the market environment and other factors that may affect future cash flows. To the extent applicable, the assumptions 
we use are consistent with forecasts that we are otherwise required to make (for example, in preparing our earnings forecasts). 
The use of this method involves inherent uncertainty. We use our best estimates in making these evaluations and consider various 
factors, including forward price curves for power and fuel costs and forecasted operating costs. However, actual future market 
prices and project costs could vary from the assumptions used in our estimates, and the impact of such variations could be material.

When we determine that our assets meet the assets held-for-sale criteria, they are reported at the lower of their carrying 
amount or fair value less the cost to sell. We are also required to evaluate our equity method investments to determine whether or 
not they are impaired when the value is considered an “other than a temporary” decline in value.

Generally, fair value will be determined using valuation techniques such as the present value of expected future cash 
flows. We will also discount the estimated future cash flows associated with the asset using a single interest rate representative of 
119

the risk involved with such an investment including contract terms, tenor and credit risk of counterparties. We may also consider 
prices of similar assets, consult with brokers, or employ other valuation techniques. We use our best estimates in making these 
evaluations and consider various factors, including forward price curves for power and fuel costs and forecasted operating costs. 
However, actual future market prices and project costs could vary from the assumptions used in our estimates, and the impact of 
such variations could be material.

During 2012 and 2011, we did not record any impairment losses. During 2010, we impaired approximately $95 million 
related  to  South  Point  (see  Note 3  for  further  information  related  to  our  acquisition  of  the  South  Point  lease  and  subsequent 
impairment of our South Point assets) and development costs of approximately $21 million associated with two development 
projects that originated prior to our Chapter 11 bankruptcy proceedings. We continued to market these projects after our Effective 
Date, but during 2010 we determined that their continued development was unlikely. 

Asset Retirement Obligation

We record all known asset retirement obligations for which the liability’s fair value can be reasonably estimated. Over 
time, the liability is accreted to its present value each period and the capitalized cost is depreciated over the useful life of the related 
asset. At December 31, 2012 and 2011, our asset retirement obligation liabilities were $38 million and $27 million, respectively, 
primarily relating to land leases upon which our power plants are built and the requirement that the property meet specific conditions 
upon its return. 

Revenue Recognition

Our operating revenues are comprised of the following:

• 

• 

• 

power and steam revenue consisting of fixed and variable capacity payments, which are not related to generation 
including capacity payments received from PJM capacity auctions, variable payments for power and steam, which 
are related to generation, host steam and RECs from our Geysers Assets, other revenues such as RMR Contracts, 
resource adequacy and certain ancillary service revenues and realized settlements from our marketing, hedging and 
optimization activities;

unrealized revenues from derivative instruments as a result of our marketing, hedging and optimization activities; 
and

other service revenues.

Power and Steam

Physical Commodity Contracts — We recognize revenue primarily from the sale of power and steam thermal energy for 

sale to our customers for use in industrial or other heating operations upon transmission and delivery to the customer.

We routinely enter into physical commodity contracts for sales of our generated power to manage risk and capture the 
value inherent in our generation. Such contracts often meet the criteria of a derivative but are generally eligible for and designated 
under the normal purchase normal sale exemption. We apply lease accounting to contracts that meet the definition of a lease and 
accrual accounting treatment to those contracts that are either exempt from derivative accounting or do not meet the definition of 
a derivative instrument. Additionally, we determine whether the financial statement presentation of revenues should be on a gross 
or net basis.

With respect to our physical executory contracts, where we act as a principal, we take title of the commodities and assume 
the risks and rewards of ownership by receiving the natural gas and using the natural gas in our operations to generate and deliver 
the power. Where we act as principal, we record settlement of our physical commodity contracts on a gross basis. Where we do 
not take title of the commodities but receive a net variable payment to convert natural gas into power and steam in a tolling 
operation, we record the variable payment as revenue but do not record any fuel and purchased energy expense.

Capacity  payments,  RMR  Contracts,  RECs,  resource  adequacy  and  other  ancillary  revenues  are  recognized  when 

contractually earned and consist of revenues received from our customers either at the market price or a contract price.

Realized and Unrealized Revenues from Commodity Derivative Instruments

Realized Settlements of Commodity Derivative Instruments — The realized value of power commodity sales and purchase 
contracts that are net settled or settled as gross sales and purchases, but could have been net settled, are reflected on a net basis 
and are included in Commodity revenue on our Consolidated Statements of Operations.   

120

 
Unrealized  Mark-to-Market  Gain  (Loss)  —  The  changes  in  the  unrealized  mark-to-market  value  of  power-based 

commodity derivative instruments are reflected on a net basis as a separate component of operating revenues.

Leases — We have contracts, such as certain tolling agreements, which we account for as operating leases under U.S. 
GAAP. Generally, we levelize certain components of these contract revenues on a straight-line basis over the term of the contract. 
The total contractual future minimum lease rentals for our contracts accounted for as operating leases, excluding tolling agreements 
related to power plants under construction, at December 31, 2012, are as follows (in millions):

Accounting for Derivative Instruments

We enter into a variety of derivative instruments including both exchange traded and OTC power and natural gas forwards, 
options as well as instruments that settle on the power price to natural gas price relationships (Heat Rate swaps and options) and 
interest rate swaps. We recognize all derivative instruments that qualify for derivative accounting treatment as either assets or 
liabilities and measure those instruments at fair value unless they qualify for and are designated under the normal purchase normal 
sale exemption. Accounting for derivatives at fair value requires us to make estimates about future prices during periods for which 
price quotes are not available from sources external to us, in which case we rely on internally developed price estimates. See Note 
8 for a further discussion on our accounting for derivatives.

Fuel and Purchased Energy Expense

Fuel and purchased energy expense is comprised of the cost of natural gas and fuel oil purchased from third parties for 
the purposes of consumption in our power plants as fuel, and the cost of power and natural gas purchased from third parties for 
our  marketing,  hedging  and  optimization  activities  and  realized  settlements  and  unrealized  mark-to-market  gains  and  losses 
resulting from general market price movements against certain derivative natural gas contracts including financial gas transactions 
economically hedging anticipated future power sales that do not qualify for hedge accounting treatment.

Realized and Unrealized Expenses from Commodity Derivative Instruments

Realized  Settlements  of  Commodity  Derivative  Instruments  —  The  realized  value  of  natural  gas  purchase  and  sales 
commodity contracts that are net settled are reflected on a net basis and included in Commodity expense on our Consolidated 
Statements  of  Operations. Power  purchase  commodity  contracts  that  result  in  the  physical  delivery  of  power,  and  that  also 
supplement our power generation, are reflected on a gross basis and are included in Commodity expense on our Consolidated 
Statements of Operations. 

Unrealized Mark-to-Market (Gain) Loss — The changes in the unrealized mark-to-market value of natural gas-based 

commodity derivative instruments are reflected on a net basis as a separate component of fuel and purchased energy expense.

Plant Operating Expense

Plant operating expense primarily includes employee expenses, utilities, chemicals, repairs and maintenance, insurance 

and property taxes. We recognize these expenses when the service is performed or in the period in which the expense relates.

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized 
for the future tax consequences attributable to differences between the financial statement carrying values of existing assets and 
liabilities and their respective tax basis and tax credit and NOL carryforwards. Deferred tax assets and liabilities are measured 
using enacted tax rates expected to apply to taxable income in the years in which temporary differences are expected to be recovered 
or settled. The effect on deferred tax assets and liabilities due to a change in tax rates is recognized in income in the period that 
includes the enactment date.

121

 
 
 
 
We recognize the financial statement effects of a tax position when it is more-likely-than-not, based on the technical 
merits, that the position will be sustained upon examination. A tax position that meets the more-likely-than-not recognition threshold 
is measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with a 
taxing authority. We reverse a previously recognized tax position in the first period in which it is no longer more-likely-than-not 
that the tax position would be sustained upon examination. See Note 10 for a further discussion on our income taxes.

Earnings (Loss) per Share

Basic earnings (loss) per share is calculated using the weighted average shares outstanding during the period and includes 
restricted stock units for which no future service is required as a condition to the delivery of the underlying common stock. Diluted 
earnings (loss) per share is calculated by adjusting the weighted average shares outstanding by the dilutive effect of share-based 
awards using the treasury stock method. See Note 11 for a further discussion of our earnings (loss) per share.

Stock-Based Compensation

We use the Black-Scholes option-pricing model or the Monte Carlo simulation model to estimate the fair value of our 
employee stock options on the grant date. The Black-Scholes option-pricing model and the Monte Carlo simulation model take 
into account certain variables, which are further explained in Note 12.

New Accounting Standards and Disclosure Requirements

Fair  Value  Measurement — In  May  2011,  the  FASB  issued  Accounting  Standards  Update  2011-04,  “Fair  Value 
Measurement” to clarify and amend the application or requirements relating to fair value measurements and disclosures relating 
to fair value measurements. The update stems from the FASB and the International Accounting Standards Board project to develop 
common requirements for measuring fair value and for disclosing information about fair value measurements. The update did not 
impact any of our fair value measurements but did require disclosure of the following:

• 

• 

• 

quantitative information about the unobservable inputs used in a fair value measurement that is categorized within 
level 3 of the fair value hierarchy;

for those fair value measurements categorized within level 3 of the fair value hierarchy, both the valuation processes 
used and the sensitivity of the fair value measurement to changes in unobservable inputs and the interrelationships 
between those unobservable inputs, if any; and

the categorization by level of the fair value hierarchy for items that are not measured at fair value in the statement 
of financial position but for which the fair value is required to be disclosed.

The new requirements relating to fair value measurements are prospective and effective for interim and annual periods 
beginning after December 15, 2011, with early adoption prohibited. We adopted all of the requirements related to this update at 
January 1, 2012. Since this update did not impact any of our fair value measurements and only required additional disclosures, 
adoption of this standard did not have a material impact on our financial condition, results of operations or cash flows.

Disclosures about Offsetting Assets and Liabilities — In December 2011, the FASB issued Accounting Standards Update 
2011-11, “Balance Sheet - Disclosures about Offsetting Assets and Liabilities” to enhance disclosure requirements relating to the 
offsetting of assets and liabilities on an entity's balance sheet. The update requires enhanced disclosures regarding assets and 
liabilities that are presented net or gross in the statement of financial position when the right of offset exists, or that are subject to 
an enforceable master netting arrangement. In January 2013, the FASB issued Accounting Standards Update 2013-01, “Clarifying 
the Scope of Disclosures about Offsetting Assets and Liabilities” to provide clarification that the scope previously defined in 
Accounting Standards Update 2011-11 applies to derivatives, repurchase agreements, reverse repurchase agreements and securities 
borrowing and lending transactions that are subject to an enforceable master netting arrangement or similar agreement. The new 
disclosure requirements relating to these updates are retrospective and effective for annual and interim periods beginning on or 
after January 1, 2013. These updates only require additional disclosures, as such, the adoption of these standards will not have a 
material impact on our financial condition, results of operations or cash flows.

Comprehensive Income — In February 2013, the FASB issued Accounting Standards Update 2013-02, “Reporting of 
Amounts Reclassified Out of Accumulated Other Comprehensive Income” to amend the reporting of reclassifications out of AOCI 
to require an entity to report the effect of significant reclassifications out of AOCI on the respective line items in net income if the 
amount reclassified is required under U.S. GAAP to be reclassified in its entirety to net income in the same reporting period. An 
entity shall provide this information together in one location, either on the face of the statement where net income is presented, 
or as a separate disclosure in the notes to the financial statements. The new disclosure requirements relating to this update are 
prospective and effective for interim and annual periods beginning after December 15, 2012, with early adoption permitted. This 

122

update only requires additional disclosures, as such, the adoption of this standard will not have a material impact on our financial 
condition, results of operations or cash flows.

Acquisitions, Divestitures and Discontinued Operations

Acquisition of Bosque Energy Center

On November 7, 2012, we, through our indirect, wholly-owned subsidiary Calpine Bosque Energy Center, LLC, completed 
the purchase of a power plant with a nameplate capacity of 800 MW owned by Bosque Power Co., LLC, for approximately $432 
million. The modern, natural gas-fired, combined-cycle power plant increased capacity in our Texas segment and is located in 
Central Texas near the unincorporated community of Laguna Park in Bosque County. The site includes a 250 MW generation 
block with one natural-gas turbine, one heat recovery steam generator and one steam turbine that achieved COD in June 2001 and 
a 550 MW generation block with two natural-gas turbines that went online in June 2000 as well as two heat recovery steam 
generators and one steam turbine that achieved COD in June 2011. We funded the $432 million purchase price with cash on hand. 
The purchase price was primarily allocated to property, plant and equipment. Although the purchase price allocation has not been 
finalized, we do not expect to record any material adjustments to the preliminary purchase price allocation nor do we expect to 
recognize any goodwill as a result of this acquisition.

Conectiv Acquisition

On July 1, 2010, we, through our indirect, wholly-owned subsidiary NDH, completed the Conectiv Acquisition. The 
assets acquired included 18 operating power plants and the York Energy Center that was under construction and achieved COD 
on March 2, 2011, totaling 4,491 MW of capacity. We did not acquire Conectiv’s trading book, load serving auction obligations 
or collateral requirements. Additionally, we did not assume any of Conectiv’s off-site environmental liabilities, environmental 
remediation liabilities in excess of $10 million related to assets located in New Jersey that are subject to ISRA, or pre-close 
accumulated  pension  and  retirement  welfare  liabilities;  however,  we  did  assume  pension  liabilities  on  future  services  and 
compensation increases for past services for approximately 130 grandfathered union employees who joined Calpine as a result of 
the Conectiv Acquisition. During the second half of 2010, we initiated a voluntary retirement incentive program which reduced 
the number of employees covered by our pension obligation by 31 employees. The net proceeds of $1.3 billion received from the 
NDH  Project  Debt  were  used,  together  with  available  operating  cash,  to  pay  the  Conectiv  Acquisition  purchase  price  of 
approximately $1.64 billion and also fund a cash contribution from Calpine Corporation to NDH of $110 million to fund completion 
of the York Energy Center. The NDH Project Debt was repaid in March 2011 with proceeds from borrowings under our 2018 First  
Lien Term Loans.

The Conectiv Acquisition provided us with a significant presence in the Mid-Atlantic market, one of the most robust 
competitive power markets in the U.S., and positioned us with three scale markets instead of two (California and Texas) giving 
us  greater  geographic  diversity.  We  accounted  for  the  Conectiv Acquisition  under  the  acquisition  method  of  accounting  in 
accordance with U.S. GAAP.

The following table summarizes the pro forma operating revenues and net income (loss) attributable to Calpine for 2010 
as if the Conectiv Acquisition had occurred on January 1, 2009. The pro forma information has been prepared by adding the

Acquisition of Broad River and South Point Leases

On December 8, 2010, we, through our indirect, wholly-owned subsidiary, Calpine BRSP, purchased entities from CIT 
Capital USA Inc. that held the leases for our Broad River and South Point power plants by assuming debt with a fair value of 
approximately $297 million and a cash payment of approximately $40 million. Prior to this purchase, our Broad River power plant 
was operated under a sale-leaseback transaction that was accounted for as a failed sale-leaseback financing transaction and our 
South Point power plant was accounted for as an operating lease. The purchase of the entities holding the power plant leases only 

123

added an incremental $85 million in consolidated debt, as the transaction eliminated approximately $212 million recorded as debt 
and accrued interest owed to CIT Capital USA Inc. under our Broad River power plant lease. The Calpine BRSP project debt was 
repaid in October 2012 with proceeds from borrowings under our 2019 First Lien Term Loan.

We recorded a total pre-tax loss of approximately $125 million on our Consolidated Statement of Operations for the year 

ended December 31, 2010, for this transaction, which was recorded as shown below (in millions):

Broad River: debt extinguishment costs..................................................................................................................... $

Broad River — Prior to the purchase, we operated the Broad River power plant under a lease that was accounted for as 
a failed sale-leaseback financing transaction under U.S. GAAP. The lease liability was included in project financing, notes payable 
and other debt balance and the power plant assets were included in our property, plant and equipment. As a result of the purchase, 
we did not adjust the historical value of the assets. We allocated the value of the consideration paid in the transaction based upon 
the fair value of both power plants, and the result was an allocation of assumed debt that was greater than the prior debt obligation 
resulting in a pre-tax loss of approximately $30 million. Because we primarily exchanged future lease obligations for a debt 
obligation, the resulting loss is recorded as debt extinguishment costs in accordance with U.S. GAAP.

South Point — Prior to the purchase, we accounted for the South Point lease as an operating lease. We allocated the 
consideration paid in the transaction based upon the fair value of both power plants. The result was an allocation of consideration 
paid for South Point that was in excess of the fair value of assets acquired by approximately $95 million, which was primarily 
due to the elimination of a lease levelization asset associated with the prior lease, which was no longer proper on a consolidated 
basis. The resulting loss has been reported as an impairment loss for accounting purposes.

While the transaction resulted in a one-time, pre-tax loss, in the longer-term, the acquisition of these entities grants us 
greater flexibility and more control of the future operation of both plants and simplified a previously complex leasing arrangement.

Sale of Riverside Energy Center

Our 603 MW Riverside Energy Center had a PPA that provided WP&L an option to purchase the power plant and plant-
related assets upon written notice of exercise prior to May 31, 2012. On May 18, 2012, WP&L exercised their option to purchase 
Riverside Energy Center, LLC, one of our VIEs which owned Riverside Energy Center. The sale closed on December 31, 2012 
for approximately $402 million, and we recorded a pre-tax gain of approximately $7 million, which is included in (gain) on sale 
of assets, net on our Consolidated Statements of Operations. We expect to use the sale proceeds for our capital allocation activities 
and for general corporate purposes. The sale of Riverside Energy Center did not meet the criteria for treatment as discontinued 
operations.

Sale of Broad River

On December 27, 2012, we, through our indirect, wholly-owned subsidiary Calpine Power Company, completed the sale 
of 100% of our ownership interest in each of the Broad River Entities for approximately $423 million. This transaction resulted 
in the disposition of our Broad River power plant, an 847 MW natural gas-fired, peaking power plant located in Gaffney, South 
Carolina, and includes a five year consulting agreement with the buyer. We recorded a pre-tax gain of approximately $215 million 
in December 2012, which is included in (gain) on sale of assets, net on our Consolidated Statements of Operations. We expect to 
use the sale proceeds for our capital allocation activities and for general corporate purposes. The sale of the Broad River Entities 
did not meet the criteria for treatment as discontinued operations.

Sale of Blue Spruce and Rocky Mountain

On December 6, 2010, we, through our indirect, wholly-owned subsidiaries Riverside Energy Center, LLC and CDHI, 
completed the sale of 100% of our ownership interests in Blue Spruce and Rocky Mountain for approximately $739 million, and 
we recorded a pre-tax gain of approximately $209 million during the fourth quarter of 2010. The results of operations for Blue 
Spruce and Rocky Mountain are reported as discontinued operations on our Consolidated Statement of Operations for the year 
ended December 31, 2010.

Variable Interest Entities and Unconsolidated Investments

We consolidate all of our VIEs where we have determined that we are the primary beneficiary. There were no changes 
to our determination of whether we are the primary beneficiary of our VIEs for the year ended December 31, 2012. We have the 
following types of VIEs consolidated in our financial statements:

Subsidiaries with Project Debt — All of our subsidiaries with project debt not guaranteed by Calpine have PPAs that 
provide financial support and are thus considered VIEs. We retain ownership and absorb the full risk of loss and potential for 
reward once the project debt is paid in full. Actions by the lender to assume control of collateral can occur only under limited 
circumstances such as upon the occurrence of an event of default, which we have determined to be unlikely. See Note 6 for further 
information regarding our project debt and Note 2 for information regarding our restricted cash balances.

Subsidiaries with PPAs — Certain of our majority owned subsidiaries have PPAs that limit the risk and reward of our 

ownership and thus constitute a VIE. 

VIE with a Purchase Option — OMEC has an agreement that provides a third party a fixed price option to purchase power 
plant assets exercisable in the year 2019 with an aggregate capacity of 608 MW. This purchase option limits the risk and reward 
of our ownership and, thus, constitutes a VIE. 

Consolidation of VIEs

We consolidate our VIEs where we determine that we have both the power to direct the activities of a VIE that most 
significantly impact the VIE’s economic performance and the obligation to absorb losses or receive benefits from the VIE. We 
have determined that we hold the obligation to absorb losses and receive benefits in all of our VIEs where we hold the majority 
equity interest. Therefore, our determination of whether to consolidate is based upon which variable interest holder has the power 
to direct the most significant activities of the VIE (the primary beneficiary). Our analysis includes consideration of the following 
primary  activities  which  we  believe  to  have  a  significant  impact  on  a  power  plant’s  financial  performance:  operations  and 
maintenance, plant dispatch, and fuel strategy as well as our ability to control or influence contracting and overall plant strategy. 
Our approach to determining which entity holds the powers and rights is based on powers held as of the balance sheet date. 
Contractual terms that may change the powers held in future periods, such as a purchase or sale option, are not considered in our 
analysis. Based on our analysis, we believe that we hold the power and rights to direct the most significant activities of all our 
majority-owned VIEs.

Under our consolidation policy and under U.S. GAAP we also:

• 

• 

perform an ongoing reassessment each reporting period of whether we are the primary beneficiary of our VIEs; and

evaluate  if  an  entity  is  a  VIE  and  whether  we  are  the  primary  beneficiary  whenever  any  changes  in  facts  and 
circumstances occur such that the holders of the equity investment at risk, as a group, lose the power from voting 
rights or similar rights of those investments to direct the activities of a VIE that most significantly impact the VIE’s 
economic performance or when there are other changes in the powers held by individual variable interest holders.

Noncontrolling Interest — We own a 75% interest in Russell City Energy Company, LLC, one of our VIEs, which is also 
25% owned by a third party. We fully consolidate this entity in our Consolidated Financial Statements and account for the third 
party ownership interest as a noncontrolling interest.

VIE Disclosures

Our consolidated VIEs include natural gas-fired power plants with an aggregate capacity of 8,255 MW and 11,391 MW, 
at December 31, 2012 and 2011, respectively. For these VIEs, we may provide other operational and administrative support through 
various affiliate contractual arrangements among the VIEs, Calpine Corporation and its other wholly-owned subsidiaries whereby 
we support the VIE through the reimbursement of costs and/or the purchase and sale of energy. In addition to amounts contractually 
required, we provided support to these VIEs in the form of cash and other contributions of $20 million and $87 million for the 
years ended December 31, 2012 and 2011, respectively. During the year ended December 31, 2010, we provided $540 million to 
NDH, an indirect, wholly-owned subsidiary, to fund the Conectiv Acquisition, including $110 million to complete the construction 
of the York Energy Center. Additionally, we provided support to our other VIEs in the form of cash and other contributions other 
than amounts contractually required of $46 million during the year ended December 31, 2010. 

U.S. GAAP requires separate disclosure on the face of our Consolidated Balance Sheets of the significant assets of a 
consolidated VIE that can be used only to settle obligations of the consolidated VIE and the significant liabilities of a consolidated 

126

VIE for which creditors (or beneficial interest holders) do not have recourse to the general credit of the primary beneficiary. In 
determining which assets of our VIEs meet the separate disclosure criteria, we consider that this separate disclosure requirement 
is met where Calpine Corporation is substantially limited or prohibited from access to assets (primarily cash and cash equivalents, 
restricted cash and property, plant and equipment), and where our VIEs had project financing that prohibits the VIE from providing 
guarantees on the debt of others. In determining which liabilities of our VIEs meet the separate disclosure criteria, we consider 
that this separate disclosure requirement is met where there are agreements that prohibit the debt holders of the VIEs from recourse 
to the general credit of Calpine Corporation and where the amounts were material to our financial statements.

Unconsolidated VIEs and Investments

We have a 50% partnership interest in Greenfield LP and in Whitby. Greenfield LP and Whitby are also VIEs; however, 
we do not have the power to direct the most significant activities of these entities and therefore do not consolidate them. We account 
for these entities under the equity method of accounting and include our net equity interest in investments on our Consolidated 
Balance Sheets. At December 31, 2012 and 2011, our equity method investments included on our Consolidated Balance Sheets 
were comprised of the following (in millions):

Our risk of loss related to our unconsolidated VIEs is limited to our investment balance. Holders of the debt of our 
unconsolidated investments do not have recourse to Calpine Corporation and its other subsidiaries; therefore, the debt of our 
unconsolidated investments is not reflected on our Consolidated Balance Sheets. At December 31, 2012 and 2011, equity method 
investee debt was approximately $448 million and $462 million, respectively, and based on our pro rata share of each of the 
investments, our share of such debt would be approximately $224 million and $231 million at December 31, 2012 and 2011, 
respectively.

Our equity interest in the net income from Greenfield LP and Whitby for the years ended December 31, 2012, 2011 and 
2010, are recorded in (income) from unconsolidated investments in power plants. The following table sets forth details of our

Greenfield LP — Greenfield LP is a limited partnership between certain subsidiaries of ours and of Mitsui & Co., Ltd. 
and contains the Greenfield Energy Centre, a 1,038 MW natural gas-fired, combined-cycle power plant located in Ontario, Canada 
which is operated by a third party. We and Mitsui & Co., Ltd. each hold a 50% interest in Greenfield LP. Greenfield LP holds an 
18-year term loan with an original principal amount of CAD $648 million. Borrowings under the project finance facility bear 
interest at Canadian LIBOR plus 1.125% or Canadian prime rate plus 0.125%.

Whitby — Whitby is a limited partnership between certain subsidiaries of ours and Atlantic Packaging Ltd., which operates 
the Whitby facility, a 50 MW natural gas-fired, simple-cycle cogeneration power plant located in Ontario, Canada. We and Atlantic 
Packaging Ltd. each hold a 50% partnership interest in Whitby.

Inland Empire Energy Center Put and Call Options — We hold a call option to purchase the Inland Empire Energy Center 
(a 775 MW natural gas-fired power plant located in California which achieved COD on May 3, 2010) from GE that may be 
exercised between years 2017 and 2024. GE holds a put option whereby they can require us to purchase the power plant, if certain 
plant performance criteria are met by 2025. We determined that we are not the primary beneficiary of the Inland Empire power 
plant, and we do not consolidate it due to the fact that GE directs the most significant activities of the power plant including 
operations and maintenance.

(1)  Our weighted average interest rate calculation includes the amortization of deferred financing costs and debt discount.

Our First Lien Notes are secured equally and ratably with indebtedness incurred under our First Lien Term Loans and 
Corporate  Revolving  Facility,  subject  to  certain  exceptions  and  permitted  liens,  on  substantially  all  of  our  and  certain  of  the 
guarantors’ existing and future assets. Additionally, our First Lien Notes rank equally in right of payment with all of our and the 
129

 
 
 
guarantors’ other existing and future senior indebtedness, and will be effectively subordinated in right of payment to all existing 
and future liabilities of our subsidiaries that do not guarantee our First Lien Notes.

Subject to certain qualifications and exceptions, our First Lien Notes will, among other things, limit our ability and the 

ability of the guarantors to:

• 

• 

• 

• 

• 

incur or guarantee additional first lien indebtedness;

enter into certain types of commodity hedge agreements that can be secured by first lien collateral; 

enter into sale and leaseback transactions; 

create or incur liens; and 

consolidate, merge or transfer all or substantially all of our assets and the assets of our restricted subsidiaries on a 
combined basis.

On October 9, 2012, we issued notice to the holders of our First Lien Notes of our intent to redeem 10% of the aggregate 
principal amount of each series of our existing First Lien Notes. On November 7, 2012, we completed the redemption at a redemption 
price of 103% of the principal amount redeemed, plus accrued and unpaid interest. This redemption was funded using a portion 
of the proceeds received from the issuance of the 2019 First Lien Term Loan discussed further below.

First Lien Term Loans

Our First Lien Term Loans provide for senior secured term loan facilities and bear interest, at our option, at either (i) the 
base rate, equal to the higher of the Federal Funds effective rate plus 0.5% per annum or the Prime Rate (as such terms are defined 
in the First Lien Term Loans credit agreements), plus an applicable margin of 2.25%, or (ii) LIBOR plus 3.25% per annum subject 
to a LIBOR floor of 1.25%. An aggregate amount equal to 0.25% of the aggregate principal amount of the First Lien Term Loans 
will be payable at the end of each quarter with the remaining balance payable on the maturity date. The First Lien Term Loans are 
subject to certain qualifications and exceptions, similar to our First Lien Notes. The 2018 First Lien Term Loans have a maturity 
date of April 1, 2018.

On October 9, 2012, we entered into and borrowed $835 million under our 2019 First Lien Term Loan, which bears 
interest at the same rate as our First Lien Term Loans (discussed above). We used the net proceeds received to redeem 10% of the 
aggregate principal amount of each series of our existing First Lien Notes at a redemption price of 103% of the principal amount 
redeemed and to repay project debt totaling $218 million, plus accrued and unpaid interest for each. The 2019 First Lien Term 
Loan allows us to reduce our overall cost of debt by replacing a portion of our First Lien Notes with fixed interest rates ranging 
from 7.25% to 8.0% with a corporate level term loan carrying a lower variable interest rate currently at 4.5% and to repay variable 
rate project debt.

The 2019 First Lien Term Loan carries substantially the same terms as the 2018 First Lien Term Loans and matures on 
October 9, 2019. The 2019 First Lien Term Loan also contains substantially similar covenants, qualifications, exceptions and 
limitations as the 2018 First Lien Term Loans and First Lien Notes. We recorded debt extinguishment costs of approximately $18 
million associated with the redemption premium, the write-off of unamortized deferred financing costs and debt premium and 
discount during the fourth quarter of 2012.

Our project financings are collateralized solely by the capital stock or partnership interests, physical assets, contracts 
and/or cash flows attributable to the entities that own the power plants. The lenders’ recourse under these project financings is 
limited to such collateral.

CCFC Notes

On May 19, 2009, our wholly-owned subsidiaries, CCFC and CCFC Finance, issued approximately $1.0 billion aggregate 
principal amount of 8.0% CCFC Notes in a private placement. The CCFC Notes and the related guarantees are secured, subject 
to certain exceptions and permitted liens, by all real and personal property of CCFC and CCFC’s material subsidiaries (including 
the CCFC Guarantors), consisting primarily of six natural gas power plants as well as the equity interests in CCFC and the CCFC 
Guarantors. The CCFC Notes are not guaranteed by Calpine Corporation and are without recourse to Calpine Corporation or any 
of our other non-CCFC or CCFC Finance subsidiaries or assets; however, CCFC generates the majority of its cash flows from an 
intercompany  tolling  agreement  with  CES  and  has  various  service  agreements  in  place  with  other  subsidiaries  of  Calpine 
Corporation. The CCFC Notes mature on June 1, 2016 and the weighted average interest rates, which includes the amortization 
of deferred financing costs and debt discount, was 8.9% for both 2012 and 2011.

(1)  Amounts are accounted for as financing transactions under U.S. GAAP and are included in our project financing, notes 

payable and other amounts above.

The primary types of property leased by us are power plants and related equipment. The leases generally provide for the 
lessee to pay taxes, maintenance, insurance, and certain other operating costs of the leased property. The remaining lease terms 
range up to 36 years (including lease renewal options). Some of the lease agreements contain customary restrictions on dividends 
up  to  Calpine  Corporation,  additional  debt  and  further  encumbrances  similar  to  those  typically  found  in  project  financing 
agreements. At December 31, 2012 and 2011, the asset balances for the leased assets totaled approximately $880 million and $879 
million with accumulated amortization of $312 million and $318 million, respectively. See Note 15 for discussion of capital leases 
guaranteed by Calpine Corporation.

The Corporate Revolving Facility represents our primary revolving facility. Borrowings under the Corporate Revolving 
Facility bear interest, at our option, at either a base rate or LIBOR rate. Base rate borrowings shall be at the base rate, plus an 
applicable margin ranging from 2.00% to 2.25% as provided in the Corporate Revolving Facility credit agreement. Base rate is 
defined as the higher of (i) the Federal Funds Effective Rate, as published by the Federal Reserve Bank of New York, plus 0.50% 
and (ii) the rate the administrative agent announces from time to time as its prime per annum rate. LIBOR rate borrowings shall 
be at the British Bankers’ Association Interest Settlement Rates for the interest period as selected by us as a one, two, three, six 
or, if agreed by all relevant lenders, nine or twelve month interest period, plus an applicable margin ranging from 3.00% to 3.25%. 
Interest payments are due on the last business day of each calendar quarter for base rate loans and the earlier of (i) the last day of 
the interest period selected or (ii) each day that is three months (or a whole multiple thereof) after the first day for the interest 
period selected for LIBOR rate loans. Letter of credit fees for issuances of letters of credit include fronting fees equal to that 
percentage per annum as may be separately agreed upon between us and the issuing lenders and a participation fee for the lenders 
equal to the applicable interest margin for LIBOR rate borrowings. Drawings under letters of credit shall be repaid within two 
business days or be converted into borrowings as provided in the Corporate Revolving Facility credit agreement. We incur an 
unused commitment fee ranging from 0.50% to 0.75% on the unused amount of commitments under the Corporate Revolving 
Facility. 

132

The Corporate Revolving Facility does not contain any requirements for mandatory prepayments, except in the case of 
certain designated asset sales in excess of $3 billion in the aggregate. However, we may voluntarily repay, in whole or in part, the 
Corporate Revolving Facility, together with any accrued but unpaid interest, with prior notice and without premium or penalty. 
Amounts repaid may be reborrowed, and we may also voluntarily reduce the commitments under the Corporate Revolving Facility 
without premium or penalty. The Corporate Revolving Facility matures on December 10, 2015. 

The Corporate Revolving Facility is guaranteed and secured by each of our current domestic subsidiaries that was a 
guarantor under the First Lien Credit Facility and will also be additionally guaranteed by our future domestic subsidiaries that are 
required to provide such a guarantee in accordance with the terms of the Corporate Revolving Facility. The Corporate Revolving 
Facility ranks equally in right of payment with all of our and the guarantors’ other existing and future senior indebtedness and will 
be effectively subordinated in right of payment to all existing and future liabilities of our subsidiaries that do not guarantee the 
Corporate Revolving Facility. The Corporate Revolving Facility also requires compliance with financial covenants that include a 
minimum cash interest coverage ratio and a maximum net leverage ratio.

CDHI

We also have a letter of credit facility related to CDHI. On January 10, 2012, we increased the CDHI letter of credit 
facility to $300 million and extended the maturity date to January 2, 2016. As a result of the completion of the sale of Riverside 
Energy Center, LLC, a wholly-owned subsidiary of CDHI, on December 31, 2012, we are required to cash collateralize letters of 
credit issued in excess of $225 million until replacement collateral is contributed to the CDHI collateral package which we are in 
the process of arranging. At December 31, 2012, we had $28 million of cash collateral posted in support of outstanding letters of 
credit under our CDHI letter of credit facility. We do not believe that this change will have a material impact on our liquidity.

Fair Value of Debt

We record our debt instruments based on contractual terms, net of any applicable premium or discount. We did not elect 
to apply the alternative U.S. GAAP provisions of the fair value option for recording financial assets and financial liabilities. The 
following table details the fair values and carrying values of our debt instruments at December 31, 2012 and 2011 (in millions):

Excludes a lease that is accounted for as a failed sale-leaseback transaction under U.S. GAAP.

On January 1, 2012, we adopted Accounting Standards Update 2011-04 “Fair Value Measurement” which requires the 
categorization by level of the fair value hierarchy for items not measured at fair value on our Consolidated Balance Sheets but for 
which fair value is required to be disclosed. We measure the fair value of our First Lien Notes, First Lien Term Loans and CCFC 
Notes using market information, including quoted market prices or dealer quotes for the identical liability when traded as an asset 
(categorized  as  level  2). We  measure  the  fair  value  of  our  project  financing,  notes  payable  and  other  debt  instruments  using 
discounted cash flow analyses based on our current borrowing rates for similar types of borrowing arrangements (categorized as 
level 3). We do not have any debt instruments with fair value measurements categorized as level 1 within the fair value hierarchy.

7. 

Assets and Liabilities with Recurring Fair Value Measurements

Cash Equivalents — Highly liquid investments which meet the definition of cash equivalents, primarily investments in 
money market accounts, are included in both our cash and cash equivalents and our restricted cash on our Consolidated Balance 
Sheets. Certain of our money market accounts invest in U.S. Treasury securities or other obligations issued or guaranteed by the 
U.S. Government, its agencies or instrumentalities. Our cash equivalents are classified within level 1 of the fair value hierarchy.

Margin Deposits and Margin Deposits Held by Us Posted by Our Counterparties — Margin deposits and margin deposits 
held by us posted by our counterparties represent cash collateral paid between our counterparties and us to support our commodity 

133

 
 
contracts. Our margin deposits and margin deposits held by us posted by our counterparties are generally cash and cash equivalents 
and are classified within level 1 of the fair value hierarchy.

Derivatives — The primary factors affecting the fair value of our derivative instruments at any point in time are the 
volume of open derivative positions (MMBtu, MWh and $ notional amounts); changing commodity market prices, primarily for 
power and natural gas; our credit standing and that of our counterparties for energy commodity derivatives; and prevailing interest 
rates for our interest rate swaps. Prices for power and natural gas and interest rates are volatile, which can result in material changes 
in the fair value measurements reported in our financial statements in the future.

We utilize market data, such as pricing services and broker quotes, and assumptions that we believe market participants 
would use in pricing our assets or liabilities including assumptions about the risks inherent to the inputs in the valuation technique. 
These inputs can be either readily observable, market corroborated or generally unobservable. The market data obtained from 
broker pricing services is evaluated to determine the nature of the quotes obtained and, where accepted as a reliable quote, used 
to validate our assessment of fair value. We use other qualitative assessments to determine the level of activity in any given market. 
We primarily apply the market approach and income approach for recurring fair value measurements and utilize what we believe 
to be the best available information. We utilize valuation techniques that seek to maximize the use of observable inputs and minimize 
the use of unobservable inputs. We classify fair value balances based on the observability of those inputs.

The fair value of our derivatives includes consideration of our credit standing, the credit standing of our counterparties 
and the impact of credit enhancements, if any. We have also recorded credit reserves in the determination of fair value based on 
our expectation of how market participants would determine fair value. Such valuation adjustments are generally based on market 
evidence, if available, or our best estimate.

Our level 1 fair value derivative instruments primarily consist of natural gas swaps, futures and options traded on the 

NYMEX.

Our level 2 fair value derivative instruments primarily consist of interest rate swaps and OTC power and natural gas 
forwards for which market-based pricing inputs are observable. Generally, we obtain our level 2 pricing inputs from market sources 
such as the Intercontinental Exchange and Bloomberg. To the extent we obtain prices from brokers in the marketplace, we have 
procedures  in  place  to  ensure  that  prices  represent  executable  prices  for  market  participants.  In  certain  instances,  our  level 2 
derivative  instruments  may  utilize  models  to  measure  fair  value.  These  models  are  primarily  industry-standard  models  that 
incorporate various assumptions, including quoted interest rates, correlation, volatility, as well as other relevant economic measures. 
Substantially all of these assumptions are observable in the marketplace throughout the full term of the instrument, can be derived 
from observable data or are supported by observable levels at which transactions are executed in the marketplace.

Our level 3 fair value derivative instruments may consist of OTC power and natural gas forwards and options where 
pricing inputs are unobservable, as well as other complex and structured transactions. Complex or structured transactions are 
tailored to our or our customers’ needs and can introduce the need for internally-developed model inputs which might not be 
observable in or corroborated by the market. When such inputs have a significant impact on the measurement of fair value, the 
instrument  is  categorized  in  level 3.  Our  valuation  models  may  incorporate  historical  correlation  information  and  extrapolate 
available broker and other information to future periods. In cases where there is no corroborating market information available to 
support significant model inputs, we initially use the transaction price as the best estimate of fair value. OTC options are valued 
using industry-standard models, including the Black-Scholes option-pricing model. At each balance sheet date, we perform an 
analysis of all instruments subject to fair value measurement and include in level 3 all of those whose fair value is based on 
significant unobservable inputs.

134

Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the 
fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment 
and may affect our estimate of the fair value of our assets and liabilities and their placement within the fair value hierarchy levels. 
The following tables present our financial assets and liabilities that were accounted for at fair value on a recurring basis as of  
December 31, 2012 and 2011, by level within the fair value hierarchy:

(4) 

There were no significant transfers into level 3 for the years ended December 31, 2012 and 2010. We had $2 million in 
losses transferred out of level 2 into level 3 for the year ended December 31, 2011 due to changes in market liquidity in 
various power and natural gas markets. 

(5)  We had no significant transfers out of level 3 for the years ended December 31, 2012 and 2011. There were $3 million in 
losses transferred out of level 3 into level 2 for the year ended December 31, 2010 due to changes in market liquidity in 
various power markets.

At December 31, 2012, the derivative instruments classified as level 3 primarily included a longer-term OTC traded 
commodity contract extending through 2014. This contract is classified as level 3 because the contract terms exceed the period 
for which liquid market rate information is available. As such, the fair value of the contract incorporates extrapolation assumptions 
made in the determination of the market price for future delivery periods in which applicable commodity prices were either not 
observable or lacked corroborative market data. The fair value of the net derivative position classified as level 3 is predominantly 
driven by market commodity prices; however, given the nature of our net derivative position, we do not believe that a significant 
change in market commodity prices would have a material impact on our level 3 net fair value. The following table presents 
quantitative information for the unobservable inputs used in our most significant level 3 fair value measurements at December 31,

Derivative Instruments

Types of Derivative Instruments and Volumetric Information

Commodity Instruments — We are exposed to changes in prices for the purchase and sale of power, natural gas and other 
energy commodities. We use derivatives, which include physical commodity contracts and financial commodity instruments such 
as OTC and exchange traded swaps, futures, options, forward agreements and instruments that settle on the power price to natural 
gas price relationships (Heat Rate swaps and options) or instruments that settle on power price relationships between delivery 
points for the purchase and sale of power and natural gas to attempt to maximize the risk-adjusted returns by economically hedging 
a portion of the commodity price risk associated with our assets. By entering into these transactions, we are able to economically 
hedge a portion of our Spark Spread at estimated generation and prevailing price levels.

Interest Rate Swaps — A portion of our debt is indexed to base rates, primarily LIBOR. We have historically used interest 
rate swaps to adjust the mix between fixed and floating rate debt to hedge our interest rate risk for potential adverse changes in 
interest rates. As of December 31, 2012, the maximum length of time over which we were hedging using interest rate derivative 
instruments designated as cash flow hedges was 11 years.

As of December 31, 2012 and 2011, the net forward notional buy (sell) position of our outstanding commodity and 
interest rate swap contracts that did not qualify under the normal purchase normal sale exemption were as follows (in millions):

(1)  Approximately $4.1 billion at December 31, 2011 was related to hedges of our First Lien Credit Facility’s variable rate 
debt that was converted to fixed rate debt. On March 26, 2012, we terminated the interest rate swaps formerly hedging our 
First Lien Credit Facility.

Certain of our derivative instruments contain credit risk-related contingent provisions that require us to maintain collateral 
balances consistent with our credit ratings. If our credit rating were to be downgraded, it could require us to post additional collateral 
or could potentially allow our counterparty to request immediate, full settlement on certain derivative instruments in liability 
positions. Currently, we do not believe that it is probable that any additional collateral posted as a result of a one credit notch 
downgrade from its current level would be material. The aggregate fair value of our derivative liabilities with credit risk-related 
contingent provisions as of December 31, 2012, was $5 million for which we have posted collateral of $1 million by posting 
margin deposits or granting additional first priority liens on the assets currently subject to first priority liens under our First Lien 
Notes, First Lien Term Loans and Corporate Revolving Facility. However, if our credit rating were downgraded by one notch from 
its current level, we estimate that additional collateral of $1 million would be required and that no counterparty could request 
immediate, full settlement.

Accounting for Derivative Instruments

We recognize all derivative instruments that qualify for derivative accounting treatment as either assets or liabilities and 
measure those instruments at fair value unless they qualify for, and we elect, the normal purchase normal sale exemption. For 
transactions in which we elect the normal purchase normal sale exemption, gains and losses are not reflected on our Consolidated 
Statements of Operations until the period of delivery. In order to simplify our reporting, we elected to discontinue the application 
of hedge accounting treatment during the first quarter of 2012 for all commodity derivatives, including the remaining commodity 
derivatives previously accounted for as cash flow hedges. Accordingly, prospective changes in fair value from the date of this 
election are reflected in unrealized mark-to-market gain/loss on our Consolidated Statements of Operations and could create more 
volatility in our earnings. Revenues and fuel costs derived from instruments that qualified for hedge accounting or represent an 
economic hedge are recorded in the same financial statement line item as the item being hedged. Although we have discontinued 
the application of hedge accounting treatment for our commodity derivative instruments, prior to this change and for our interest 
rate swaps, hedge accounting requires us to formally document, designate and assess the effectiveness of transactions that receive 
hedge accounting. We present the cash flows from our derivatives in the same category as the item being hedged (or economically 
hedged) within operating activities or investing activities (in the case of settlements for our interest rate swaps formerly hedging 
our  First  Lien  Credit  Facility  term  loans)  on  our  Consolidated  Statements  of  Cash  Flows  unless  they  contain  an  other-than-
insignificant financing element in which case their cash flows are classified within financing activities.

137

Cash Flow Hedges — We report the effective portion of the unrealized gain or loss on a derivative instrument designated 
and qualifying as a cash flow hedging instrument as a component of OCI and reclassify such gains and losses into earnings in the 
same period during which the hedged forecasted transaction affects earnings. Gains and losses due to ineffectiveness on commodity 
hedging instruments are recognized currently in earnings and are separately stated on our Consolidated Statements of Operations 
in  unrealized  mark-to-market  gain/loss  as  a  component  of  operating  revenues  (for  power  contracts  and  swaps)  and  fuel  and 
purchased energy expense (for natural gas contracts and swaps). Gains and losses due to ineffectiveness on interest rate  hedging 
instruments are recognized currently in earnings as a component of interest expense (for interest rate swaps except as discussed 
below).  If  it  is  determined  that  the  forecasted  transaction  is  no  longer  probable  of  occurring,  then  hedge  accounting  will  be 
discontinued prospectively and future changes in fair value are recorded in earnings. If the hedging instrument is terminated or 
de-designated prior to the occurrence of the hedged forecasted transaction, the net accumulated gain or loss associated with the 
changes in fair value of the hedge instrument remains deferred in AOCI until such time as the forecasted transaction impacts 
earnings or until it is determined that the forecasted transaction is probable of not occurring. 

Derivatives Not Designated as Hedging Instruments — We enter into power, natural gas and interest rate transactions 
that primarily act as economic hedges to our asset and interest rate portfolio, but either do not qualify as hedges under the hedge 
accounting guidelines or qualify under the hedge accounting guidelines and the hedge accounting designation has not been elected. 
Changes in fair value of commodity derivatives not designated as hedging instruments are recognized currently in earnings and 
are separately stated on our Consolidated Statements of Operations in unrealized mark-to-market gain/loss as a component of 
operating revenues (for power contracts and Heat Rate swaps and options) and fuel and purchased energy expense (for natural 
gas contracts, swaps and options). Changes in fair value of interest rate derivatives not designated as hedging instruments are 
recognized currently in earnings as interest expense (for interest rate swaps except as discussed below).

Interest Rate Swaps Formerly Hedging our First Lien Credit Facility and Other Project Debt — During 2010, we repaid 
approximately $3.5 billion of our First Lien Credit Facility term loans, which had approximately $3.3 billion notional amount of 
interest rate swaps hedging the scheduled variable interest payments, and in January 2011, we repaid the remaining approximately 
$1.2 billion of First Lien Credit Facility term loans which had approximately $1.0 billion notional amount of interest rate swaps 
hedging the scheduled variable interest payments. With the repayment of the remaining First Lien Credit Facility term loans, 
unrealized losses of approximately $91 million in AOCI related to the interest rate swaps formerly hedging the First Lien Credit 
Facility, were reclassified out of AOCI and into earnings as an additional loss on interest rate derivatives during 2011. In addition, 
we reclassified approximately $17 million in unrealized losses in AOCI to loss on interest rate derivatives during 2011 resulting 
from the repayment of project debt in 2011. During 2010, we reclassified approximately $206 million out of AOCI and into earnings 
as additional loss on interest rate derivatives related to interest rate swaps formerly hedging our First Lien Credit Facility term 
loans. We have presented the reclassification of unrealized losses from AOCI into earnings and the changes in fair value and 
settlements subsequent to the reclassification date of the interest rate swaps formerly hedging our First Lien Credit Facility described 
above separate from interest expense as loss on interest rate derivatives on our Consolidated Statements of Operations. On March 
26, 2012, we terminated the legacy interest rate swaps formerly hedging our First Lien Credit Facility and paid the fair value of 
the swaps totaling approximately $156 million. Approximately $14 million of the settlement amount was recorded as a component 
of  loss  on  interest  rate  derivatives  on  our  Consolidated  Statement  of  Operations  for  the  year  ended  December 31,  2012,  and 
approximately $142 million reflected the realization of losses recorded in prior periods.

(1)  Cumulative cash flow hedge losses, net of tax, remaining in AOCI were $242 million and $172 million at December 31, 

2012 and 2011, respectively.

(2)  Reclassification of losses from OCI to earnings consisted of $32 million from the reclassification of interest rate contracts 
due to settlement for each of the years ended December 31, 2012 and 2011, $15 million in losses from terminated interest 
rate contracts due to the repayment of project debt in 2011, and $91 million in losses from existing interest rate contracts

reclassified from OCI into earnings due to the refinancing of variable rate First Lien Credit Facility term loans for the year 
ended December 31, 2011.

(3) 

Included in Commodity revenue and Commodity expense on our Consolidated Statements of Operations.

As a result of our election to discontinue hedge accounting treatment for our commodity derivatives accounted for as 
cash flow hedges, the fair value of our commodity derivative instruments that previously resided in AOCI on the de-designation 
date was reclassified to earnings during 2012 as the related hedged transactions affected earnings. Thus, there is no fair value 
amounts related to commodity derivatives remaining in AOCI at December 31, 2012. We estimate that pre-tax net losses of $41 
million (comprised of amounts related to interest rate swaps) would be reclassified from AOCI into earnings during the next 12 
months as the hedged transactions settle; however, the actual amounts that will be reclassified will likely vary based on changes 
in interest rates. Therefore, we are unable to predict what the actual reclassification from AOCI into earnings (positive or negative) 
will be for the next 12 months.

Use of Collateral

We use margin deposits, prepayments and letters of credit as credit support with and from our counterparties for commodity 
procurement and risk management activities. In addition, we have granted additional first priority liens on the assets currently 
subject to first priority liens under various debt agreements as collateral under certain of our power and natural gas agreements 
and certain of our interest rate swap agreements in order to reduce the cash collateral and letters of credit that we would otherwise 
be required to provide to the counterparties under such agreements. The counterparties under such agreements share the benefits 
of the collateral subject to such first priority liens pro rata with the lenders under our various debt agreements.

The table below summarizes the balances outstanding under margin deposits, natural gas and power prepayments, and 
exposure  under  letters  of  credit  and  first  priority  liens  for  commodity  procurement  and  risk  management  activities  as  of 
December 31, 2012 and 2011 (in millions):

Consolidation of CCFC and Calpine Tax Reporting Groups — For federal income tax reporting purposes, our historical 
tax reporting group was comprised primarily of two separate groups, CCFC and its subsidiaries, which we referred to as the CCFC 
group, and Calpine Corporation and its subsidiaries other than CCFC, which we referred to as the Calpine group. During the first 
quarter of 2011, we elected to consolidate our CCFC and Calpine groups for federal income tax reporting purposes and Calpine 
filed a consolidated federal income tax return for the year ended December 31, 2011 that included the CCFC group. As a result 
of the consolidation, the CCFC group deferred tax liabilities will be eligible to offset existing Calpine group NOLs that were 
reserved by a valuation allowance. Accordingly, we recorded a one-time federal deferred income tax benefit of approximately $76 
million during the first quarter of 2011 to reduce our valuation allowance. For the year ended December 31, 2010, the CCFC group 
was deconsolidated from the Calpine group for federal income tax reporting purposes.

Intraperiod Tax Allocation — In accordance with U.S. GAAP, intraperiod tax allocation provisions require allocation of 
a tax expense (benefit) to continuing operations due to current OCI gains (losses) and income from discontinued operations with 
a partial offsetting amount recognized in OCI and discontinued operations. The following table details the effects of our intraperiod 
tax allocations for the years ended December 31, 2012, 2011 and 2010 (in millions).

NOL Carryforwards — Our NOL carryforwards consist primarily of federal NOL carryforwards of approximately $7.3 
billion,  which  expire  between  2023  and  2031,  and  NOL  carryforwards  in  33  states  and  the  District  of  Columbia  totaling 
approximately  $4.0  billion,  which  expire  between  2013  and  2031,  substantially  all  of  which  are  offset  with  a  full  valuation 
allowance. We also have approximately $1.0 billion in foreign NOLs, substantially all of which are offset with a full valuation 
allowance. The NOL carryforwards available are subject to limitations on their annual usage. Under federal and applicable state 
income tax laws, a corporation is generally permitted to deduct from taxable income in any year NOLs carried forward from prior 
years subject to certain time limitations as prescribed by the taxing authorities. Under federal income tax law, our NOL carryforwards 
can be utilized to reduce future taxable income subject to certain limitations, including if we were to undergo an ownership change 
as defined by Section 382 of the IRC. We experienced an ownership change on the Effective Date as a result of the cancellation 
of our old common stock and the distribution of our new common stock pursuant to our Plan of Reorganization. However, this 
ownership change and the resulting annual limitations are not expected to result in the expiration of our NOL carryforwards if we 
are able to generate sufficient future taxable income within the carryforward periods. At December 31, 2012, approximately $2.4 
billion of our $7.3 billion federal NOLs are not subject to annual Section 382 limitations. When considering our cumulative annual 
Section  382  limitations,  in  addition  to  our  post-Effective  Date  NOLs  that  are  not  limited,  our  total  unrestricted  NOLs  are 
approximately $7.1 billion. If a subsequent ownership change were to occur as a result of future transactions in our common stock, 
accompanied by a significant reduction in our market value immediately prior to the ownership change, our ability to utilize the 
NOL carryforwards may be significantly limited. 

Deferred tax assets relating to tax benefits of employee stock-based compensation do not reflect stock options exercised 
and restricted stock that vested in 2012. Some stock option exercises and restricted stock vestings result in tax deductions in excess 
of previously recorded deferred tax benefits based on the equity award value at the grant date. Although these additional tax 
benefits or “windfalls” are reflected in net operating tax carryforwards pursuant to accounting for stock-based compensation under 
U.S. GAAP, the additional tax benefit associated with the windfall is not recognized until the deduction reduces taxes payable, 
which will not occur for Calpine until a future period. Accordingly, since the tax benefit does not reduce our current taxes payable 
in 2012 due to NOL carryforwards, these “windfall” tax benefits are not reflected in our NOL in deferred tax assets for 2012. 
Windfalls included in NOL carryforwards, but not reflected in deferred tax assets as of December 31, 2012 were $10 million. 

Under state income tax laws, our NOL carryforwards can be utilized to reduce future taxable income subject to certain 
limitations, including if we were to undergo an ownership change as defined by Section 382 of the IRC. During 2011, we analyzed 
the effect of our change in ownership on the Effective Date for each of our significant states to determine the amount of our NOL 
limitation. The analysis determined that $640 million of our state NOLs are expected to expire unutilized as a result of statutory 
limitations on the use of some of our pre-emergence date NOLs as of the Effective Date or the cessation of business operations 
in various tax jurisdictions. We reduced our deferred tax asset for state NOLs that we are unable to utilize and made an equal 
reduction in our valuation allowance in 2011. The result did not have an impact on our income tax expense in 2011. We estimate 
that approximately $117 million of our state NOLs expired unutilized during 2012 as a result of statutory state limitations relating 
to the time period NOLs can be carried forward, and accordingly, we reduced our deferred tax asset and made an equal reduction 
in our valuation allowance. The reduction did not have an impact to our income tax expense in 2012. We will likely make future 
annual adjustments to our state NOLs that have expired or are limited under Section 382 of the IRC.

In 2011, we had certain intercompany accounts payable/receivable balances that were eliminated as part of the final steps 
of our emergence from bankruptcy. There was no effect to our federal NOLs, however, there was a reduction in our state NOLs 
of $44 million which was partially offset by a reduction in current state taxable income of $24 million. The resulting net reduction 
to our state NOLs was offset by an equal reduction in our valuation allowance. The reduction did not have an impact on our income 
tax expense in 2011.

As a result of the settlement of certain bankruptcy claims and the final distribution to the holders of allowed unsecured 
claims in accordance with our Plan of Reorganization in 2011, we recognized approximately $66 million and $39 million for 

144

federal and state income tax purposes, respectively, in cancellation of debt income related to this distribution for federal income 
tax reporting in 2011.

Income Tax Audits — We remain subject to various audits and reviews by taxing authorities; however, we do not expect 
these will have a material effect on our tax provision. Any NOLs we claim in future years to reduce taxable income could be 
subject to IRS examination regardless of when the NOLs occurred. Due to significant NOLs, any adjustment of state returns or 
federal returns would likely result in a reduction of deferred tax assets rather than a cash payment of income taxes.

Canadian Tax Audits — In September 2009, we received notice from the Canadian Revenue Authority, or CRA, of their 
intent to conduct a limited scope income tax audit on four of our Canadian subsidiaries for the tax years 2005 through 2008. The 
CRA concluded that there were no adjustments on two of the subsidiaries, but further review was required on the remaining two 
subsidiaries. On April 23, 2012, the remaining two subsidiaries received proposed adjustments from the CRA regarding our transfer 
pricing positions. On June 21, 2012, we met with the CRA to discuss their proposed adjustments and provided clarification where 
we believed it was needed. In July 2012, we received additional questions from the CRA as a result of our meeting, and we 
responded to their request in September and October 2012. In December 2012, we received and responded to additional questions 
from the CRA. In January 2013, we received an adjusted reassessment on one of the two transfer pricing issues that we are disputing 
with the CRA and are currently evaluating the merits of the adjusted reassessment. If accepted, any adjustments to our transfer 
pricing would increase taxable income and would be offset entirely by existing NOL's to which a valuation allowance has been 
applied. Any interest assessments resulting from acceptance of the CRA offer would be immaterial. 

We continue to evaluate the remaining proposed adjustments on our other Canadian subsidiary; however, based on our 
current analysis which is supported by our tax advisors, we believe that our transfer pricing positions and policies are appropriate, 
and we intend to challenge the CRA’s proposed adjustments. If we are unsuccessful in our challenge, any adjustment to Canadian 
taxable income would first be offset against the existing NOLs that are available; however, we do not believe any reassessment 
resulting in an adjustment to taxable income which is greater than our existing NOLs, or including interest or penalties which 
cannot be offset by existing NOLs, would have a material adverse effect on our financial condition, results of operations or cash 
flows.

Valuation Allowance — U.S. GAAP requires that we consider all available evidence, both positive and negative, and tax 
planning strategies to determine whether, based on the weight of that evidence, a valuation allowance is needed to reduce the value 
of deferred tax assets. Future realization of the tax benefit of an existing deductible temporary difference or carryforward ultimately 
depends on the existence of sufficient taxable income of the appropriate character within the carryback or carryforward periods 
available under the tax law. Due to our history of losses, we were unable to assume future profits; however, since our emergence 
from Chapter 11, we are able to consider available tax planning strategies.

As of December 31, 2012, we have provided a valuation allowance of approximately $2.2 billion on certain federal, state 
and foreign tax jurisdiction deferred tax assets to reduce the amount of these assets to the extent necessary to result in an amount 
that is more likely than not to be realized. The net change in our valuation allowance was a decrease of $114 million, $50 million 
and $186 million for the years ended December 31, 2012, 2011 and 2010, respectively; all primarily related to changes in our 
estimates of our ability to utilize our NOL carryforwards.

Unrecognized Tax Benefits

At December 31, 2012, we had unrecognized tax benefits of $92 million. If recognized, $36 million of our unrecognized 
tax benefits could impact the annual effective tax rate and $56 million, related to deferred tax assets, could be offset against the 
recorded valuation allowance resulting in no impact to our effective tax rate. We also had accrued interest and penalties of $24 
million for income tax matters at December 31, 2012. We recognize interest and penalties related to unrecognized tax benefits in 
income tax expense (benefit) on our Consolidated Statements of Operations. We believe that it is reasonably possible that a decrease 
within the range of approximately nil and $28 million in unrecognized tax benefits could occur within the next 12 months primarily 
related to state and foreign tax issues.

U.S. Federal Income Tax Refund

In 2004, we deducted a portion of our foreign dividends as allowed by the IRC when we filed our federal income tax 
return. Upon further review and analysis, we determined our foreign dividends should have been offset against our current 2004 
operating loss. In 2009, we filed an amended federal income tax return that reflected this change and would result in a refund of 
approximately $10 million. This amended federal return has been under audit by the IRS since it was filed. In October 2012, the 
IRS approved our amended tax return, and we received a refund of approximately $13 million which included approximately $3 
million in accrued interest. The benefit of this refund is reflected in our Consolidated Financial Statements in the fourth quarter 
of 2012.

11.  Earnings (Loss) per Share

Pursuant to our Plan of Reorganization, all shares of our common stock outstanding prior to the Effective Date were 
canceled and the issuance of 485 million new shares of reorganized Calpine Corporation common stock was authorized to resolve 
allowed unsecured claims. A portion of the 485 million authorized shares was immediately distributed, and the remainder was 
reserved for distribution to holders of certain disputed claims that, although allowed as of the Effective Date, were unresolved. In 
June 2011, we settled the largest remaining claim outstanding and began the process of distributing the balance of the reserved 
shares, which was completed during the third quarter of 2011, pursuant to our Plan of Reorganization. Accordingly, although the 
reserved shares were not issued and outstanding for the entire balance of the periods presented, all conditions of distribution had 
been met for these reserved shares as of the Effective Date, and such shares are considered issued and are included in our calculation 
of weighted average shares outstanding. We also include restricted stock units for which no future service is required as a condition 
to the delivery of the underlying common stock in our calculation of weighted average shares outstanding.

As we incurred a net loss for the year ended December 31, 2011, diluted loss per share for this period is computed on 

the same basis as basic loss per share, as the inclusion of any other potential shares outstanding would be anti-dilutive.

Reconciliations of the amounts used in the basic and diluted earnings (loss) per common share computations for the years 

ended December 31, 2012, 2011 and 2010, are as follows (shares in thousands):

Stock-Based Compensation

Calpine Equity Incentive Plans

The Calpine Equity Incentive Plans provide for the issuance of equity awards to all non-union employees as well as the 
non-employee  members  of  our  Board  of  Directors. The  equity  awards  may  include  incentive  or  non-qualified  stock  options, 

146

restricted stock, restricted stock units, stock appreciation rights, performance compensation awards and other share-based awards. 
The equity awards granted under the Calpine Equity Incentive Plans include both graded and cliff vesting options which vest over 
periods between one and five years, contain contractual terms between approximately five and ten years and are subject to forfeiture 
provisions under certain circumstances, including termination of employment prior to vesting. At December 31, 2012, there were 
567,000 and 27,533,000 shares of our common stock authorized for issuance to participants under the Director Plan and the Equity 
Plan, respectively.

We use the Black-Scholes option-pricing model or the Monte Carlo simulation model, as appropriate, to estimate the fair 
value of our employee stock options on the grant date, which takes into account the exercise price and expected term of the stock 
option, the current price of the underlying stock and its expected volatility, expected dividends on the stock and the risk-free 
interest rate for the expected term of the stock option as of the grant date. For our restricted stock and restricted stock units, we 
use our closing stock price on the date of grant, or the last trading day preceding the grant date for restricted stock granted on non-
trading days, as the fair value for measuring compensation expense. Stock-based compensation expense is recognized over the 
period in which the related employee services are rendered. The service period is generally presumed to begin on the grant date 
and end when the equity award is fully vested. We use the graded vesting attribution method to recognize fair value of the equity 
award over the service period. For example, the graded vesting attribution method views one three-year option grant with annual 
graded vesting as three separate sub-grants, each representing 33 1/3% of the total number of stock options granted. The first sub-
grant vests over one year, the second sub-grant vests over two years and the third sub-grant vests over three years. A three-year 
option grant with cliff vesting is viewed as one grant vesting over three years.

Stock-based  compensation  expense  recognized  was  $25  million,  $24  million  and  $24  million  for  the  years  ended 
December 31, 2012, 2011 and 2010, respectively. We did not record any significant tax benefits related to stock-based compensation 
expense in any period as we are not benefiting from a significant portion of our deferred tax assets, including deductions related 
to stock-based compensation expense. In addition, we did not capitalize any stock-based compensation expense as part of the cost 
of an asset for the years ended December 31, 2012, 2011 and 2010. At December 31, 2012, there was unrecognized compensation 
cost of $6 million related to options, $25 million related to restricted stock and nil related to restricted stock units, which is expected 
to be recognized over a weighted average period of 0.8 years for options, 1.3 years for restricted stock and 0.4 years for restricted 
stock  units. We  issue  new  shares  from  our  share  reserves  set  aside  for  the  Calpine  Equity  Incentive  Plans  and  employment 
inducement options when stock options are exercised and for other share-based awards.

A summary of all of our non-qualified stock option activity for the Calpine Equity Incentive Plans for the year ended 

December 31, 2012, is as follows:

13.  Defined Contribution and Defined Benefit Plans

We maintain two defined contribution savings plans that are intended to be tax exempt under Sections 401(a) and 501
(a) of the IRC. Our non-union plan generally covers employees who are not covered by a collective bargaining agreement, and 
our union plan covers employees who are covered by a collective bargaining agreement. We recorded expenses for these plans of 
approximately $11 million, $10 million and $9 million for the years ended December 31, 2012, 2011 and 2010, respectively. 
Employer matching contributions are 100% of the first 5% of compensation a participant defers for the non-union plan. The 
employee deferral limit is 75% of eligible compensation under both plans.

As part of the Conectiv Acquisition, we assumed approximately $6 million of pension liability for approximately 130 
grandfathered  union  employees  who  joined  Calpine  as  a  result  of  the  Conectiv Acquisition  and  enrolled  them  into  the  New 
Development Holdings, LLC Union Retirement Plan, a defined benefit plan. PHI retained the pension liability associated with 
prior service cost; however, we are responsible for benefits for services after July 1, 2010 and future compensation increases 
related to prior service. During the second half of 2010, we initiated  a voluntary retirement incentive program which reduced our 
pension obligation by 31 employees. Under the New Development Holdings, LLC Union Retirement Plan, retirement benefits 
are  primarily  a  function  of  age  attained,  years  of  participation,  years  of  service,  vesting  and  level  of  compensation. As  of 
December 31, 2012 and 2011, our pension assets, liabilities and related costs were not material to us.  As of December 31, 2012 
and 2011, there were approximately $12 million and $10 million in plan assets and approximately $21 million and $18 million in 
pension liabilities, respectively. Our net pension liability recorded on our Consolidated Balance Sheets as of December 31, 2012 
and 2011, was approximately $9 million and $8 million, respectively. For the years ended December 31, 2012, 2011 and 2010, 
we recognized net periodic benefit costs of approximately $1 million, $1 million and $9 million, respectively. Net pension benefit 
costs for 2010 includes a one-time charge to pension expense for a voluntary retirement incentive program of approximately $8 
million. The voluntary retirement incentive program was accepted by 31 of the 48 eligible employees that were retained as part 
of the Conectiv Acquisition allowing these employees the ability to commence receiving retirement benefits early without reducing 

148

their overall pension benefits. Our net periodic benefit cost is included in plant operating expense on our Consolidated Statements 
of Operations. As of December 31, 2012 and 2011, the total amount recognized in AOCI for actuarial losses related to pension 
obligation was approximately $1 million and $3 million, respectively.

In making our estimates of our pension obligation and related costs, we utilize discount rates, rates of compensation 
increases and rates of return on our assets that we believe are reasonable. Due to relatively small size of our pension liability 
(which is not considered material), significant changes in these assumptions would not have a material effect on our pension 
liability. During 2012 and 2011, we made contributions of approximately $2 million and $3 million, respectively, and estimated 
contributions to the pension plan are expected to be approximately $1 million in 2013. Estimated future benefit payments to 
participants in each of the next five years are expected to be approximately $1 million in each year.

14.  Capital Structure

Common Stock

Pursuant to our Plan of Reorganization, all shares of our common stock outstanding prior to the Effective Date were 
canceled and the issuance of 485 million new shares of reorganized Calpine Corporation common stock was authorized to resolve 
allowed unsecured claims. A portion of the 485 million authorized shares was immediately distributed, and the remainder was 
reserved for distribution to holders of certain disputed claims that, although allowed as of the Effective Date, were unresolved. In 
June 2011, we settled the largest remaining claim outstanding and began the process of distributing the balance of the reserved 
shares, which was completed during the third quarter of 2011, pursuant to our Plan of Reorganization. 

Our authorized common stock consists of 1.4 billion shares of Calpine Corporation common stock. Common stock issued 
as of December 31, 2012 and 2011, was 492,495,100 shares and 490,468,815 shares, respectively, at a par value of $0.001 per 
share. Common stock outstanding as of December 31, 2012 and 2011, was 457,048,970 shares and 481,743,738 shares, respectively.

As of December 31, 2012 and 2011, we had treasury stock of 35,446,130 shares and 8,725,077 shares, respectively, with 
a cost of $594 million and $125 million, respectively. On August 23, 2011, we announced that our Board of Directors had authorized 
the repurchase of up to $300 million in shares of our common stock. In April 2012, our Board of Directors authorized us to double 
the size of our share repurchase program, increasing our permitted cumulative repurchases to $600 million in shares of our common 
stock. As of the filing of this Report, we have completed our previously announced $600 million share repurchase program, having 
repurchased a total of 35,568,833 shares of our outstanding common stock at an average price paid of $16.87 per share. In February 
2013, our Board of Directors authorized the repurchase of an additional $400 million in shares of our common stock, bringing the 
cumulative authorization total to $1.0 billion. Our treasury stock also consists of our common stock withheld to satisfy federal, 
state and local income tax withholding requirements for vested employee restricted stock awards. All treasury stock is held at cost.

15.  Commitments and Contingencies

Long-Term Service Agreements

As of December 31, 2012, the total estimated commitments for LTSAs associated with turbines installed or in storage 
were approximately $68 million. These commitments are payable over the terms of the respective agreements, which range from 
1 to 5 years. LTSA future commitment estimates are based on the stated payment terms in the contracts at the time of execution 
and are subject to an annual inflationary adjustment. Certain of these agreements have terms that allow us to cancel the contracts 
for a fee. If we cancel such contracts, the estimated commitments remaining for LTSAs would be reduced.

Power Plant, Land and Other Operating Leases

We have entered into certain long-term operating leases for power plants, extending through 2020, which include renewal 
options or purchase options at fair value and contain customary restrictions on dividends up to Calpine Corporation, additional 
debt and further encumbrances similar to those typically found in project finance agreements. Payments on our operating leases, 
which may contain escalation clauses or step rent provisions, are recognized on a straight-line basis. Certain capital improvements 
associated with leased power plants may be deemed to be leasehold improvements and are amortized over the shorter of the term 
of the lease or the economic life of the capital improvement. We have also entered into various land and other operating leases for 
ground facilities and operations, which extend through 2069. Future minimum lease payments under these leases are as follows

During the years ended December 31, 2012, 2011 and 2010, rent expense for power plant and land and other operating 

leases amounted to $51 million, $53 million and $60 million, respectively.

Production Royalties and Leases

We are obligated under numerous geothermal leases and right-of-way, easement and surface agreements. The geothermal 
leases generally provide for royalties based on production revenue with reductions for property taxes paid. The right-of-way, 
easement and surface agreements are based on flat rates or adjusted based on consumer price index changes and are not material. 
Under the terms of most geothermal leases, the royalties accrue as a percentage of power revenues. Certain properties also have 
net profits and overriding royalty interests that are in addition to the land base lease royalties. Some lease agreements contain 
clauses providing for minimum lease payments to lessors if production temporarily ceases or if production falls below a specified 
level. Production royalties for geothermal power plants for the years ended December 31, 2012, 2011 and 2010, were $22 million, 
$22 million and $25 million, respectively.

Lease payments are subject to adjustments for our pro rata portion of annual increases or decreases in building operating 
costs. During the years ended December 31, 2012, 2011 and 2010, rent expense for noncancellable operating leases was $12 
million, $13 million and $12 million, respectively.

Natural Gas Purchases

We enter into natural gas purchase contracts of various terms with third parties to supply natural gas to our natural gas-
fired power plants. The majority of our purchases are made in the spot market or under index-priced contracts. At December 31, 
2012, we had future commitments of approximately $3.0 billion for natural gas purchases under contracts with terms from 1 to 
13 years, and one contract with a term of 29 years.

Guarantees and Indemnifications

As part of our normal business operations, we enter into various agreements providing, or otherwise arranging, financial 
or performance assurance to third parties on behalf of our subsidiaries in the ordinary course of such subsidiaries’ respective 
business. Such arrangements include guarantees, standby letters of credit and surety bonds for power and natural gas purchase 
and sale arrangements and contracts associated with the development, construction, operation and maintenance of our fleet of 
power plants. These arrangements are entered into primarily to support or enhance the creditworthiness otherwise attributed to a 
subsidiary on a stand-alone basis, thereby facilitating the extension of sufficient credit to accomplish the subsidiaries’ intended 
commercial purposes.

At December 31, 2012, guarantees of subsidiary debt, standby letters of credit and surety bonds to third parties and 

guarantees of subsidiary operating lease payments and their respective expiration dates were as follows (in millions):

These are contingent off balance sheet obligations.

(5)  As of December 31, 2012, $3 million of cash collateral is outstanding related to these bonds.

We routinely arrange for the issuance of letters of credit and various forms of surety bonds to third parties in support of 
our subsidiaries’ contractual arrangements of the types described above and may guarantee the operating performance of some of 
151

our partially-owned subsidiaries up to our ownership percentage. The letters of credit issued under various credit facilities support 
CES  risk  management  and  other  operational  and  construction  activities.  In  the  event  a  subsidiary  were  to  fail  to  perform  its 
obligations under a contract supported by such a letter of credit or surety bond, and the issuing bank or surety were to make 
payment to the third party, we would be responsible for reimbursing the issuing bank or surety within an agreed timeframe, typically 
a period of one to ten days. To the extent liabilities are incurred as a result of activities covered by letters of credit or the surety 
bonds, such liabilities are included on our Consolidated Balance Sheets.

Commercial Agreements — In connection with the purchase and sale of power, natural gas and emission allowances to 
and from third parties with respect to the operation of our power plants, we may be required to guarantee a portion of the obligations 
of  certain  of  our  subsidiaries. These  guarantees  may  include  future  payment  obligations  and  effectively guarantee  our  future 
performance under certain agreements.

Asset Acquisition and Disposition Agreements — In connection with our purchase and sale agreements, we have frequently 
provided for indemnification to the counterparty for liabilities incurred as a result of a breach of a representation or warranty by 
the indemnifying party. These indemnification obligations generally have a discrete term and are intended to protect the parties 
against risks that are difficult to predict or impossible to quantify at the time of the consummation of a particular transaction.

Other — Additionally, we and our subsidiaries from time to time assume other guarantee and indemnification obligations 
in conjunction with other transactions such as parts supply agreements, construction agreements and equipment lease agreements. 
These guarantee and indemnification obligations may include future payment obligations and effectively guarantee our future 
performance under certain agreements.

Our potential exposure under guarantee and indemnification obligations can range from a specified amount to an unlimited 
dollar amount, depending on the nature of the claim and the particular transaction. Our total maximum exposure under our guarantee 
and indemnification obligations is not estimable due to uncertainty as to whether claims will be made or how any potential claim 
will be resolved. As of December 31, 2012, there are no outstanding claims related to our guarantee and indemnification obligations 
and  we  do  not  anticipate  that  we  will  be  required  to  make  any  material  payments  under  our  guarantee  and  indemnification 
obligations.

We are party to various litigation matters, including regulatory and administrative proceedings arising out of the normal 
course of business. At the present time, we do not expect that the outcome of any of these proceedings will have a material adverse 
effect on our financial condition, results of operations or cash flows.

On a quarterly basis, we review our litigation activities and determine if an unfavorable outcome to us is considered 
“remote,” “reasonably possible” or “probable” as defined by U.S. GAAP. Where we determine an unfavorable outcome is probable 
and is reasonably estimable, we accrue for potential litigation losses. The liability we may ultimately incur with respect to such 
litigation matters, in the event of a negative outcome, may be in excess of amounts currently accrued, if any; however, we do not 
expect that the reasonably possible outcome of these litigation matters would, individually or in the aggregate, have a material 
adverse effect on our financial condition, results of operations or cash flows. Where we determine an unfavorable outcome is not 
probable or reasonably estimable, we do not accrue for any potential litigation loss. The ultimate outcome of these litigation matters 
cannot presently be determined, nor can the liability that could potentially result from a negative outcome be reasonably estimated. 
As a result, we give no assurance that such litigation matters would, individually or in the aggregate, not have a material adverse 
effect on our financial condition, results of operations or cash flows.

Environmental Matters

We are subject to complex and stringent environmental laws and regulations related to the operation of our power plants. 
On occasion, we may incur environmental fees, penalties and fines associated with the operation of our power plants. At the present 
time, we do not have environmental violations or other matters that would have a material impact on our financial condition, 
results of operations or cash flows or that would significantly change our operations.

Segment and Significant Customer Information

We assess our business on a regional basis due to the impact on our financial performance of the differing characteristics 
of these regions, particularly with respect to competition, regulation and other factors impacting supply and demand. At December 
31, 2012, our reportable segments were West (including geothermal), Texas, North (including Canada) and Southeast. We continue 
to evaluate the optimal manner in which we assess our performance including our segments and future changes may result.

Commodity Margin is a key operational measure reviewed by our chief operating decision maker to assess the performance 

of our segments. The tables below show our financial data for our segments for the periods indicated (in millions).

17.  Quarterly Consolidated Financial Data (unaudited)

 Our quarterly operating results have fluctuated in the past and may continue to do so in the future as a result of a number 
of factors, including, but not limited to, our restructuring activities (including asset sales), the completion of development projects, 
the timing and amount of curtailment of operations under the terms of certain PPAs, the degree of risk management and marketing, 
hedging and optimization activities, energy commodity market prices and variations in levels of production. Furthermore, the 
majority of the dollar value of capacity payments under certain of our PPAs are received during the months of May through October.

Delivering Effective

Capital Allocation

As a management team, we are committed to being good stewards of your

capital. Our goal is to deliver Adjusted Free Cash Flow Per Share growth

of 15 – 20% compounded annually. We strive to do this by identifying high-

return growth projects while also opportunistically repurchasing our stock,

which we believe represents an investment in clean, efficient and flexible

natural gas-fired generation at attractive prices. As America moves toward

clean, affordable natural gas as the preferred fuel for power generation and

as the electric grid requires more flexible power generation to integrate inter-

mittent renewable power to assure reliability of electric supply, we believe

Calpine’s fleet is uniquely positioned to benefit from the combination of these

secular and fundamental trends that favor combined-cycle natural gas-fired

power generation as the technology of choice for America’s future.

Calpine’s management team rings the closing

bell at the New York Stock Exchange (L to R):

Thad Hill (President and COO), Jack Fusco

(CEO), Thad Miller (EVP and CLO) and

Zamir Rauf (EVP and CFO).
