DEAR FELLOW SHAREHOLDERS

In 2016, we again delivered on our financial commitments.  We achieved Adjusted EBITDA of $1.815 billion and
Adjusted Free Cash Flow of $736 million, mee(cid:2)ng our guidance for the eighth consecu(cid:2)ve year.  This achievement
reflects the collec(cid:2)ve effort of our en(cid:2)re organiza(cid:2)on, par(cid:2)cularly in light of the challenging power markets we
faced last year.  Yet, delivering on this commitment was just the beginning for us in 2016.

COMMITMENT TO OUR STRATEGY 

Over the past year, we con(cid:2)nued to execute on our strategic
objec(cid:2)ves to further op(cid:2)mize our wholesale power genera(cid:2)on
footprint and to complement our fleet with customer­driven
solu(cid:2)ons. Across the board, the Calpine team succeeded on
these fronts.

• We divested our Mankato and Osprey power plants
at a(cid:4)rac(cid:2)ve economics. Collec(cid:2)vely, we sold these
non­core plants at an Enterprise Value to Adjusted
EBITDA mul(cid:2)ple of approximately 12x, consistent with
our track record of value­crea(cid:2)ng dives(cid:2)tures. Our
effec(cid:2)ve por(cid:6)olio management efforts (including both
dives(cid:2)tures and acquisi(cid:2)ons) over the past several years
have allowed us to successfully achieve our geographic
diversity and market scale objec(cid:2)ves.

• We recycled the proceeds of our asset sales into the
purchases of two retail pla(cid:6)orms: Calpine Energy

Solu(cid:2)ons (“Solu(cid:2)ons,” formerly Noble Americas Energy
Solu(cid:2)ons) and North American Power. The addi(cid:2)on of
Solu(cid:2)ons strategically expanded our retail customer
base to include large­scale commercial and industrial
organiza(cid:2)ons with highly customized product needs.
Given a geographic footprint that dovetails nicely with
our wholesale fleet, and given its ability to target new
customers via a direct marke(cid:2)ng approach, Solu(cid:2)ons is
a natural partner to Champion Energy Services, the
retail pla(cid:6)orm we acquired in 2015. At the same (cid:2)me,
our acquisi(cid:2)on of North American Power represents a
bolt­on to the Champion pla(cid:6)orm that expands our
residen(cid:2)al presence in the Northeast while leveraging
the exis(cid:2)ng Champion organiza(cid:2)on. As you can see from
the figure at le(cid:7), our retail pla(cid:6)orm now has a na(cid:2)onal
footprint and a full spectrum of service offerings to
various types of customers. Therefore, we believe that
our retail por(cid:6)olio is now strategically complete.
• Beyond expanding our retail presence, we remained
focused on our customer­facing origina(cid:2)on efforts to
further op(cid:2)mize our wholesale fleet. During the past
year, we have signed approximately 900 MW of term
power and steam contracts across our core regions.

COMMITMENT TO OUR SHAREHOLDERS

ost importantly, Calpine remains commi(cid:5)ed to its shareholders.
As we look to 2017, we will be focused on three key areas that
we believe will drive value for the organiza(cid:2)on:

• Maintain opera(cid:2)onal excellence, which includes not only
our best­in­class plant performance but also our ability
to deliver on our financial guidance.

• Successfully integrate our retail pla(cid:8)orms and posi(cid:2)on
them for further growth. We now have three dis(cid:2)nct
retail sales channels: direct large commercial and
industrial (C&I), indirect or broker­driven business with
small C&I, and residen(cid:2)al mass market. Ours is a strong
pla(cid:8)orm that strategically complements our wholesale
footprint, and as we move forward with integra(cid:2)on, we
will balance common back­end systems with unique
customer acquisi(cid:2)on approaches across the en(cid:2)(cid:2)es.
• And finally, we are focused on shrinking our balance

sheet to both improve the risk profile of the company
and create greater flexibility. We have announced a
plan to pay down $2.7 billion of debt by the end of
2019 and have already begun execu(cid:2)ng upon it.
Despite our solid confidence in our business, the lack
of sponsorship in the public equi(cid:2)es space today has
focused us on delevering first and foremost, even while
leaving us with several hundred million dollars of capital
available for deployment.

We, like you, believe that the equity markets are overlooking
the compelling opportunity presented by our con(cid:2)nued strong
Adjusted Free Cash Flow, declining growth capital expenditures
and our ability to substan(cid:2)ally delever through 2019. It is our
belief that as we con(cid:2)nue to deliver on all our commitments,
including those to our shareholders, the equity market will
recognize the value our stock represents. Although the near
term path is set, over (cid:2)me we believe the strong cash flow
genera(cid:2)on of our business will enable not only further
delevering but also new investment and the return of capital
to our shareholders.

Thank you for your con(cid:2)nued support of Calpine.

Sincerely,

Frank Cassidy
Chairman of the Board

Thad Hill
President and Chief Execu(cid:2)ve Officer

The acquisition of Calpine Energy Solutions, one of the nation's largest
direct commercial and industrial retailers, has expanded our retail 
presence and enhanced the value of our power generation fleet.

Frank Cassidy, Chairman of the Board, and 
Thad Hill, President and Chief Executive Officer

COMMITMENT TO THE FUTURE

The Calpine investment thesis centers on the future of the
power genera(cid:2)on industry and the secular trends that are
shaping it. Regardless of any change in federal administra(cid:2)on,
an irreversible shi(cid:3) is already underway. The abundance
and sustained affordability of natural gas, coupled with the
increasing penetra(cid:2)on of intermi(cid:5)ent renewable genera(cid:2)on,
point to the cri(cid:2)cal role flexible natural­gas fired resources
will play in providing resilience and reliability to our na(cid:2)on’s
electric grid. We remain commi(cid:5)ed to that vision. Indeed, we
believe that our assets are unparalleled in quality, suitability
and longevity, and we focus on best­in­class opera(cid:2)ons and
maintenance to preserve their value. In addi(cid:2)on, we con(cid:2)nue
to advocate for market­based regulatory policies that preserve
the compe(cid:2)(cid:2)ve wholesale power markets in which we operate.

COMMITMENT TO OUR ORGANIZATION AND 
OUR COMMUNITIES

Calpine values its people, both within our organiza(cid:2)on and
within our communi(cid:2)es. Our accomplishments along these
lines over the past year include the following:

• We delivered our best­ever safety performance,

achieving a record­low total reportable incident rate in
2016. There is no more important achievement than that.

• We maintained our focus on costs, which helped in a

more difficult commodity environment.

• We made key leadership moves within the organiza(cid:2)on,
including bringing on veteran power industry leader
Charlie Gates as our Execu(cid:2)ve Vice President, Power
Opera(cid:2)ons. Charlie’s more than 34 years of industry
experience has been invaluable to our team and to the
leaders within it. We have also transi(cid:2)oned Trey Griggs
to the role of President, Calpine Retail, where he will
focus on the integra(cid:2)on and growth of our retail
businesses as an important sales channel for our
wholesale power.

• Within our communi(cid:2)es, we donated more than

$700,000 to chari(cid:2)es while suppor(cid:2)ng the Houston
Marathon, MS 150, Astros Founda(cid:2)on, Earth Day,
Calpine’s Texas Regional Charity Golf Tournament and
many other deserving local charitable events.

PART I

Item 1.  Business

BUSINESS AND STRATEGY

Business

We are a premier competitive power company with 80 power plants primarily in the U.S. We sell the power and related 
services we produce to our wholesale customers who include commercial and industrial end-users, state and regional wholesale 
market operators, and our retail affiliates who serve retail customers. We measure our success by delivering long-term shareholder 
value. We accomplish this through our focus on operational excellence at our power plants and in our customer and commercial 
activity, as well as through our disciplined approach to capital allocation. 

Our capital allocation philosophy seeks to maximize levered cash returns to equity while maintaining a strong balance 
sheet. We seek to enhance shareholder value through a diverse and balanced capital allocation approach that includes portfolio 
management, organic or acquisitive growth, returning capital to shareholders and debt reduction. The mix of this activity shifts 
over time given the external market environment and the opportunity set. In the current environment, we believe that paying down 
debt and strengthening our balance sheet is a high return investment for our shareholders. We also consider the repurchases of our 
own shares of common stock as an attractive investment opportunity, and we utilize the expected returns from this investment as 
the benchmark against which we evaluate all other capital allocation decisions. We believe this philosophy closely aligns our 
objectives with those of our shareholders.

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 (included in our West segment), Texas (included in our Texas segment) and the Northeast and Mid-
Atlantic regions (included in our East segment) 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 flexible and reliable 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. as well as the largest single producing power generation asset of all renewable energy in 
the state of California. 

We continue to focus on getting closer to our customers through expansion of our retail platform which began with the 
acquisition of Champion Energy in 2015 and was followed by the acquisitions of Calpine Solutions in late 2016 and North American 
Power in early 2017. Our retail portfolio has been established to provide an additional source of liquidity for our generation fleet 
as we hedge retail load from our wholesale generation assets as appropriate.

We sell 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 and other 
governmental  entities,  power  marketers  as  well  as  retail  commercial,  industrial,  governmental  and  residential  customers. We 
purchase primarily natural gas and some fuel oil as fuel for our power plants and engage in related natural gas transportation and 
storage transactions. We also purchase power for sale to our customers and purchase electric transmission rights to deliver power 
to our customers. Additionally, consistent with our Risk Management Policy, we enter into natural gas, power, environmental 
product, fuel oil and other physical and financial commodity contracts to hedge certain business risks and optimize our portfolio 
of power plants. Seasonality and weather can have a significant effect on our results of operations and are also considered in our 
hedging and optimization activities.

Subsequent to the completion of the sale of Osprey Energy Center on January 3, 2017 and the retirement of the Clear 
Lake Power Plant on February 1, 2017, our portfolio, including partnership interests, consists of 80 power plants, including one 
under construction, with an aggregate current generation capacity of 25,908 MW and 828 MW under construction. Inclusive of 
our power generation portfolio and our retail sales platforms, we serve customers in 25 states in the U.S. and in Canada and Mexico. 
Our fleet, including projects under construction, consists of 65 natural gas-fired combustion turbine-based plants, one fuel oil-
fired steam-based plant, 13 geothermal steam turbine-based plants and one photovoltaic solar plant. In 2016, our fleet of power 
plants produced approximately 110 billion KWh of electric power for our customers. In addition, we are one of the largest consumers 
of natural gas in North America. In 2016, we consumed 839 Bcf or approximately 8% of the total estimated natural gas consumed 

3

for power generation in the U.S. Our retail affiliates provided approximately 65 billion KWh to customers in 2016. We are actively 
seeking to continue to grow our wholesale and retail sales efforts. 

We believe our unique fleet compares favorably with those of our major competitors on the basis of environmental 
stewardship, scale and geographical diversity. The discovery and exploitation of natural gas from shale combined with our modern, 
efficient and flexible combined-cycle power plants has created short-term and long-term advantages. In the short-term, we are 
often the lowest cost resource to dispatch compared to Eastern coal types and oil as demonstrated in recent years when we realized 
meaningfully higher capacity factors than we have historically, given our ability to displace other fuel types and older technologies. 
In the long-term, when compared on a full life-cycle cost, we believe our power plants will be even more competitive when 
considering the greater non-fuel operating costs and potential environmental liabilities associated with other technologies and the 
flexibility needed to support the integration of intermittent renewable resources.

The environmental profile of our power plants reflects our commitment to environmental leadership and stewardship. 
We have invested the capital necessary to develop a power generation portfolio that has substantially lower air emissions compared 
to our major competitors’ power plants that use 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 affecting aquatic life. Since our plants are modern and efficient and utilize cleaner 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 scale provides the opportunity to have meaningful regulatory input, to leverage our procurement efforts for better 
pricing, terms and conditions on our goods and services, and to develop and offer a wide array of products and services to our 
customers. Finally, geographic diversity helps us manage and mitigate the effect of weather, regulatory and regional economic 
differences across our markets to provide more consistent financial performance.

To optimize the price received for the products that we produce, we utilize both wholesale and retail customer sales 
channels which include an active wholesale origination function, a residential retail channel (primarily focused in Texas and the 
Northeast and Mid-Atlantic regions), and channels that serve commercial and industrial end users through both brokered and direct 
sales.

Our principal offices are located in Houston, Texas with the principal offices of our retail affiliates located in Houston, 
Texas and San Diego, California. We also have 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  competitive  power  company  in  the  U.S.  as  viewed  by  our  employees, 
shareholders, customers and policy-makers as well as the communities in which our facilities are located. We seek to deliver long-
term shareholder value through operational excellence at our power plants and in our customer and commercial activity, as well 
as through our disciplined approach to capital allocation. Our strategy to achieve this is reflected in the following five major 
initiatives listed below and subsequently described in further detail:

• 

• 

• 

• 

• 

Focus on being a premier operating company; 

Focus on expanding our customer sales channels;

Focus on optimizing our portfolio;

Focus on advocacy and corporate responsibility; and

Focus on disciplined capital allocation.

1.  Focus on Being a 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 operate and maintain 
our fleet with the objective of ensuring that our plants remain among the most flexible in the sector and are best positioned 
to  capture  value  in  response  to  grid  needs,  especially  in  light  of  the  continued  integration  of  intermittent  renewable 
resources. 

4

•  During 2016, our employees achieved a total recordable incident rate of 0.55 recordable injuries per 100 employees 
which places us in the first quartile performance for power generation companies with 1,000 or more employees. 

•  Our entire fleet achieved a forced outage factor of 2.8% and a starting reliability of 97.9% during the year ended 

December 31, 2016. 

•  During 2016, our outage services subsidiary completed 17 major inspections and eight hot gas path inspections. 

•  For the past 16 years, our Geysers Assets have reliably generated, on average, approximately six million MWh of 

renewable power per year. 

2.  Focus on Expanding our Customer Sales Channels — We continue to focus on getting closer to our customers through 
expansion of our retail platform which began with the acquisition of Champion Energy in 2015 and was followed by the 
acquisitions of Calpine Solutions in late 2016 and North American Power in early 2017. Our retail platform geographically 
and strategically complements our wholesale generation fleet by providing forward liquidity with sufficient margins. The 
combination of our wholesale origination and retail platforms provides Calpine access to both direct and mass market 
sales channels. Our direct sales efforts aim to provide our larger customers with customized products, leveraging both 
our successful wholesale origination efforts and Calpine Solutions’ presence among large commercial and industrial 
organizations to secure new contracts. Our mass market approach relies upon our expanded Champion Energy retail 
platform to serve the needs of both residential and smaller commercial and industrial customers across the country. We 
believe that our retail platform is strategically complete and are now focused on integrating it into our business and 
optimizing its financial performance. A summary of our more significant customer sales channel efforts and retail growth 
in 2016 and through the filing of this Report is as follows: 

Wholesale

•  Our ten-year PPA with Southern California Edison for 50 MW of capacity and renewable energy from our Geysers 

Assets commencing in January 2018 was approved by the CPUC in the second quarter of 2016.  

•  We entered into a new five-year PPA with USS-POSCO Industries to provide 50 MW of energy and steam from our 
Los Medanos Energy Center commencing in January 2017 which also provides for annual extensions through 2024.

•  We entered into a new five-year steam agreement, subject to certain conditions precedent, with a wholly-owned 
subsidiary of The Dow Chemical Company to provide steam from our Texas City Power Plant through 2021. 

•  We entered into a new five-year PPA with a third party to provide 50 MW of capacity from our RockGen Energy 

Center commencing in June 2017, which increases to 100 MW of capacity commencing in June 2019.  

•  We entered into a new ten-year PPA with the Tennessee Valley Authority to provide 615 MW of energy and capacity 

from our Morgan Energy Center commencing in February 2016.  

Retail

• 

In 2016, our retail subsidiaries served approximately 65 million MWh of customer load consisting of approximately 
6.5 million annualized residential customer equivalents at December 31, 2016. 

•  During the third quarter of 2016, Champion Energy was ranked highest in customer satisfaction among Texas retail 
electric providers according to the J.D. Power 2016 Electric Provider Retail Customer Satisfaction Study. This is the 
sixth time Champion Energy has received the top ranking in the past seven years.  

•  During 2016, Champion Energy expanded its service territory to include commercial and industrial customers in 

Maine, Connecticut and California. 

•  On December 1, 2016, we completed the purchase of Calpine Solutions, formerly Noble Solutions, along with a 
swap contract for approximately $800 million plus approximately $350 million of net working capital at closing. 
We  recovered  approximately  $250  million  in  cash  subsequent  to  closing  and  expect  to  recover  an  additional 
approximately $200 million through collateral synergies and the runoff of acquired legacy hedges, substantially 
within the first year. Calpine Solutions is a commercial and industrial retail electricity provider with customers in 
19 states in the U.S., including presence in California, Texas, the Mid-Atlantic and Northeast, where our wholesale 
power generation fleet is primarily concentrated. The acquisition of this best-in-class direct energy sales platform is 
consistent with our stated goal of getting closer to our end-use customers and expands our retail customer base, 
complementing our existing retail business while providing us a valuable sales channel for reaching a much greater 
portion of the load we seek to serve. 

5

•  On January 17, 2017, we completed the purchase of North American Power for approximately $105 million, excluding 
working capital and other adjustments. North American Power is a growing retail energy supplier for homes and 
small businesses and is primarily concentrated in the Northeast U.S. where Calpine has a substantial power generation 
presence and where Champion Energy has a substantial retail sales footprint that will be enhanced by the addition 
of North American Power, which will be integrated into our Champion Energy retail platform. 

3.  Focus on Optimizing our Portfolio — Our goal is 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 actively seek to divest non-core assets where 
we  can  find  opportunities  to  do  so  accretively.  During  2016  and  through  the  filing  of  this  Report,  we  strategically 
repositioned our portfolio by adding capacity in our core regions, divesting positions in non-core markets and retiring 
uneconomic plants through the following transactions:

•  On February 5, 2016, we completed the purchase of Granite Ridge Energy Center, a power plant with a nameplate 
capacity of 745 MW (summer peaking capacity of 695 MW), for approximately $500 million, excluding working 
capital and other adjustments. The addition of this modern, efficient, natural gas-fired, combined-cycle power plant 
increased capacity in our East segment, specifically the constrained New England market. 

•  On April 1, 2016, we entered into an asset sale agreement for the sale of substantially all of the assets comprising our 
South Point Energy Center to Nevada Power Company d/b/a NV Energy for approximately $76 million plus the 
assumption  by  the  purchaser  of  existing  transmission  capacity  contracts  with  a  future  net  present  value  payment 
obligation of approximately $112 million, approximately $9 million in remaining tribal lease costs and approximately 
$21 million in near-term repairs, maintenance and capital improvements to restore the power plant to full capacity. 
The sale is subject to certain conditions precedent, as well as federal and state regulatory approvals. This transaction 
supports our effort to divest non-core assets outside our strategic concentration. In December 2016, the Nevada Public 
Utility Commission issued an order rejecting the asset sale agreement. In January 2017, Nevada Power Company 
filed a motion for reconsideration of this order. In February 2017, the FERC approved Nevada Power Company’s 
acquisition of the South Point Energy Center. However, on February 8, 2017, the Nevada Public Utility Commission 
denied Nevada Power Company’s purchase of the South Point Energy Center. Nevada Power Company has the right 
to appeal this decision. We are also currently assessing our options; however, we do not anticipate that the denial of 
the sale by the Nevada Public Utility Commission will have a material effect on our financial condition, results of 
operations or cash flows.  

•  During the third quarter of 2016, we filed with ERCOT to retire our 400 MW Clear Lake Power Plant. ERCOT 
subsequently approved our plan to discontinue operations. Built in 1985, Clear Lake utilizes an older technology. Due 
to growing maintenance costs and lack of adequate compensation in Texas, we retired the power plant on February 
1, 2017. The book value associated with our Clear Lake Power Plant is immaterial.  

•  On October 26, 2016, we completed the sale of our Mankato Power Plant, a 375 MW natural gas-fired, combined-
cycle power plant and 345 MW expansion project under advanced development located in Minnesota, to Southern 
Power  Company,  a  subsidiary  of  Southern  Company,  for  $396  million,  excluding  working  capital  and  other 
adjustments. This transaction supports our effort to divest non-core assets outside our strategic concentration. 

•  On January 3, 2017, we completed the sale of our Osprey Energy Center to Duke Energy Florida, Inc. for approximately 
$166 million, excluding working capital and other adjustments. This transaction supports our effort to divest non-core 
assets outside our strategic concentration. 

In addition, our significant ongoing projects under construction and growth initiatives are discussed below:

• 

York 2 Energy Center — York 2 Energy Center is an 828 MW dual-fuel, combined-cycle project that is co-located 
with our York Energy Center in Peach Bottom Township, Pennsylvania. Once complete, the power plant will feature 
two combustion turbines, two heat recovery steam generators and one steam turbine. The project is under construction 
and the initial 760 MW of capacity cleared PJM’s last three base residual auctions with the 68 MW of incremental 
capacity clearing the last two base residual auctions. Due to construction delays, we are now targeting COD in late 
2017. 

•  Guadalupe Peaking Energy Center — In April 2015, we executed an agreement with Guadalupe Valley Electric 
Cooperative (“GVEC”) related to the construction of a 418 MW natural gas-fired peaking power plant to be co-
located with our Guadalupe Energy Center. Under the terms of the agreement, construction of the Guadalupe Peaking 
Energy Center (“GPEC”) may commence at our discretion, so long as the power plant reaches COD by June 1, 
2019. When the power plant begins commercial operation, GVEC will purchase a 50% ownership interest in GPEC. 
Once  built,  GPEC  will  feature  two  fast-ramping  combustion  turbines  capable  of  responding  to  peaks  in  power

demand. This project represents a mutually beneficial response to our customer’s desire to have direct access to 
peaking  generation  resources,  as  it  leverages  the  benefits  of  our  existing  site  and  development  rights  and  our 
construction and operating expertise, as well as our customer’s ability to fund its investment at attractive rates, all 
while affording us the flexibility of timing the plant’s construction in response to market pricing signals. 

4.  Focus  on Advocacy  and  Corporate  Responsibility — We  recognize  that  our  business  is  heavily  influenced  by  laws, 
regulations and rules at federal, state and local levels as well as by rules of the ISOs and RTOs that oversee the competitive 
markets in which we operate. We believe that being active participants in the legislative, regulatory and rulemaking 
processes may yield better outcomes for all stakeholders, including Calpine. Our three basic areas of focus are competitive 
wholesale power markets, competitive retail power markets and environmental stewardship in power generation. Below 
are some recent examples of our advocacy efforts:

Ensuring Competitive Market Structure/Rules 

• 

Successfully advocated for the PUCT to evaluate the performance of the Operating Reserve Demand Curve, and to 
pursue improvements as necessary. The PUCT received several rounds of comments from Calpine and other market 
participants, and we are currently awaiting a decision from the agency. 

•  Worked individually and with trade groups to remove language in the proposed federal energy bill that would have 

resulted in rules that could potentially undermine the PJM and ISO-NE capacity markets.

Stopping Non-Competitive/Subsidized Generation 

• 

Participated with a coalition of generators and others opposed to the sole source PPAs between regulated utilities 
and their unregulated generation affiliates in Ohio. In response to this opposition, the FERC decided that the contracts 
were not exempt from their Edgar Standard review regarding affiliate power sales restrictions and directed both 
utilities to submit the PPAs for review and approval prior to transacting under the contracts. As a result, both of the 
regulated utilities dropped their efforts.   

•  Worked with other generators to stop legislation in Connecticut that would have provided out-of-market subsidies 
to the Millstone nuclear power plant. We expect this legislation to be reintroduced this year and will continue to 
oppose. 

5.  Focus on Disciplined Capital Allocation — We seek to enhance shareholder value through optimizing our portfolio, 
prudently managing our balance sheet and returning capital to shareholders. We continue our disciplined approach to 
capital allocation, benchmarking each decision against the opportunity to repurchase shares of our own common stock. 
In  the  current  environment,  we  believe  that  paying  down  debt  and  strengthening  our  balance  sheet  is  a  high  return 
investment for our shareholders. We further optimized our capital structure by refinancing, redeeming or amending several 
of our debt instruments during the year ended December 31, 2016: 

•  On February 8, 2016, we amended our Corporate Revolving Facility, extending the maturity by two years to June 27, 
2020, and increasing the capacity by an additional $178 million to $1,678 million through June 27, 2018, reverting 
back to $1,520 million through the maturity date. Further, we increased the letter of credit sublimit by $250 million 
to $1.0 billion and extended the maturity by two years to June 27, 2020. 

• 

In May 2016, we repaid our 2019 and 2020 First Lien Term Loans with the proceeds from our New 2023 First Lien 
Term Loan and 2026 First Lien Notes which extended the maturity on approximately $1.2 billion of corporate debt. 

•  On  December  1,  2016,  we  amended  our  Corporate  Revolving  Facility  to  increase  the  aggregate  revolving  loan 
commitments available thereunder by approximately $112 million to $1,790 million for the full term through the 
maturity date of June 27, 2020.  

• 

• 

In December 2016, we used cash on hand to redeem $120 million of our 2023 First Lien Notes, plus accrued and 
unpaid interest. 

In December 2016, we repriced our 2023 First Lien Term Loans by lowering the margin over LIBOR by 0.25% to 
2.75% and extended the maturity of our 2024 First Lien Term Loan from May 2022 to January 2024. 

•  As part of our stated goal to reduce debt and interest expense, on February 3, 2017, we issued a notice of redemption 
to repay the remaining $453 million of our outstanding 2023 First Lien Notes using cash on hand along with the 
proceeds from the New 2019 First Lien Term Loan which contains a substantially lower variable rate of LIBOR plus 
1.75% per annum. We intend to repay the New 2019 First Lien Term Loan in full by the end of 2018. This accelerates 
debt reduction and achieves substantial annual interest savings of more than $20 million.

THE MARKET FOR POWER

Our Power Markets and Market Fundamentals

The power industry represents one of the largest industries in the U.S. and affects nearly every aspect of our economy, 
with  an  estimated  end-user  market  of  approximately  $380  billion  in  power  sales  in  2016  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 legislative 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 (included in our Texas segment) and the 
Northeast and Mid-Atlantic regions (included in our East 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 competitive 
wholesale power markets in the Southeast and the Midwest. In addition to our sales of electrical power and steam, we produce 
several ancillary products for sale to our customers.

• 

• 

• 

• 

• 

First,  we  are  a  provider  of  power  to  utilities,  independent  electric  system  operators,  industrial  and  agricultural 
companies, retail power providers, municipalities and other governmental entities, power marketers as well as retail 
commercial,  industrial,  governmental  and  residential  customers.  We  continue  to  focus  on  getting  closer  to  our 
customers through expansion of our retail platform which began with the acquisition of Champion Energy in 2015 
and was followed by the acquisitions of Calpine Solutions in late 2016 and North American Power in early 2017. 
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 energy (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. We also 
sell “full requirements” electricity for wholesale and retail customers, whereby we utilize our power plants as well 
as market purchases to serve the total electricity demand of the customer even as it varies across time. 

Second, we provide capacity for sale to utilities, independent electric system operators and retail power providers. 
In various markets, retail power providers (or independent electric system operators on their behalf) 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, Mid-Atlantic and certain Midwest regional markets to address this issue. California 
has a bilateral capacity program. Texas does not presently have a capacity market or a requirement for retailers to 
ensure adequate resources.

Third, we sell RECs from our Geysers Assets in northern California. 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 or in neighboring areas. 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. We also purchase 
RECs from other sources for resale to our customers.

Fourth, our cogeneration power plants produce steam, in addition to electricity, for sale to industrial customers for 
use in their manufacturing processes 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. For 
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 emission allowances and credits, including those 
under California’s AB 32 GHG reduction program, RGGI, the federal Acid Rain and CSAPR programs and emission reduction 
credits under the federal Nonattainment New Source Review program.

8

Although all of the products mentioned above contribute to our financial performance and are the primary components 
of our Commodity Margin, the most important are our sales of wholesale power and capacity. We utilize long-term customer 
contracts for our power and steam sales where possible. For power and capacity that are not sold under customer contracts or 
longer-dated capacity auctions, we use our hedging program and retail channels and sell power into shorter term markets throughout 
the regions in which we participate.

When selling 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 rational 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 factors that most significantly affect our operations are reserve margins in each of our markets, 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 and power plant operating 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, higher capacity prices and improved bilateral contracting opportunities. Typically, the market price effect 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 have varied across our regional markets. Key trends include 
lower weather normalized load growth in some regions due to increased energy efficiency as well as rooftop solar installations, 
new  renewable  and  natural  gas-fired  supply  additions,  and  significant  retirements  of  older,  less  efficient  fossil-fueled  plants. 
Reserve margins by NERC regional assessment area for each of our segments are listed below:

In recent years and in some regional markets such as PJM, the ability of customers to curtail load or temporarily utilize 
onsite backup generation instead of grid-provided electricity, known as “demand response,” has become a meaningful portion of 
“supply” and thus contributes to reserve margin estimates. While demand response reduces demand for centralized generation 
during peak times, it typically does so at a very high variable cost. To the extent demand response resources are treated like other 
sources of supply (e.g., their variable cost-based bids are allowed to affect the market clearing price for power), high resulting 
prices benefit lower-cost units like ours. Further, demand response may discourage new investment in competing centralized 
generation plants (for example, by winning capacity auctions instead of new units). This may contribute to higher energy price 
volatility during peak energy demand periods.

The Price and Supply of Natural Gas

Approximately 96% 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 391 MW of capacity from power plants where we purchase fuel oil to 
meet generation requirements, but generally do not expect fuel oil requirements to be material to our portfolio of power plants. 
In our East segment, where the supply of natural gas can be constrained under some weather circumstances, we have approximately 
6,100 MW of dual-fueled capable power plants. 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  population  centers),  transportation 
availability and supplier financial stability issues can and do occur. When natural gas supply interruptions do occur, some of our 
power plants benefit from the ability to operate on fuel oil instead of natural gas.

The price of natural gas, economic growth and environmental regulations affect our Commodity Margin and liquidity. 
The effect 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.

Lower natural gas prices over the past six years have had a significant effect on power markets. Beginning in 2009, there 
was a significant decrease in NYMEX Henry Hub natural gas prices from a range of $6/MMBtu to $13/MMBtu during 2008 to 
an average natural gas price of $4.26/MMBtu, $2.63/MMBtu and $2.55/MMBtu during 2014, 2015 and 2016, respectively. 

The availability of non-conventional natural gas supplies, in particular shale natural gas, has been the primary driver of 
reduced natural gas prices. Access to significant deposits of shale natural gas has altered the natural gas supply landscape in the 
U.S. and has had a profound effect 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. 
Despite moderate increases in natural gas prices and some significant, weather induced regional price spikes in the winter of 2014, 
there is an emerging view that lower priced natural gas will be available for the medium to long-term future. Further, high levels 
of natural gas production relative to available pipeline export capacity in some locations such as the Marcellus shale production 
region  have  put  additional,  seasonal  downward  pressure  on  local  natural  gas  prices.  Overall,  low  natural  gas  prices  and 
corresponding low power prices have challenged the economics of nuclear and coal-fired plants, leading to numerous announced 
and potential unit retirements.

Much of our generating capacity is located in California (included in our West segment), Texas (included in our Texas 
segment) and the Northeast and Mid-Atlantic (included in our East segment) where natural gas-fired units set power prices during 
many hours. When natural gas is the price-setting fuel (i.e., natural gas prices are above coal prices in our Texas or East segments), 
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. Additionally, in the Northeast and Mid-Atlantic 
regions, we have generating units capable of burning either natural gas or fuel oil. For these units, on the rare occasions when the 
cost of consuming natural gas is excessively high relative to fuel oil, our unhedged Commodity Margin may increase as a result 
of our ability to use the lower cost fuel.

Where we operate under long-term contracts, changes in natural gas prices can have a neutral effect 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 enhance the competitiveness 
of our modern, natural gas-fired fleet by making investment in other technologies such as coal, nuclear or renewables less economic 
and, in fact, making it more challenging for existing coal and nuclear resources to continue operating economically.

Beginning in the second half of 2014 and continuing throughout 2015, global oil prices declined significantly. Brent 
crude oil (a commonly cited global oil index) spot prices fell from a 2014 high of $115 per barrel in June 2014 to a low of $35 

10

per barrel in December 2015 while moderately recovering to an average price of $44 per barrel in 2016 (per the EIA). Since U.S. 
power and natural gas prices are generally not linked to oil prices, the oil market shift has not been material to our financial 
performance. The effect going forward will also likely not be material to our financial performance. While lower oil prices may 
lead to lower oil extraction and lower power demand in some parts of the U.S., such as North Dakota and Texas, lower oil prices 
are generally considered a boon to economic growth more broadly, which typically contributes to higher electricity demand.

Weather Patterns and Natural Events

Weather generally has a significant short-term effect 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 affected by relatively cool summers or mild winters. However, 
our geographically diverse portfolio mitigates the effect on our Commodity Margin of weather in specific regions of the U.S. 
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 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, operating Heat Rate and plant operating expense. 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 effect on our Commodity Margin.

Regulatory and Environmental Trends

We believe that that our fleet is generally favored by regulatory requirements for the industry to reduce air and water 
emissions, including those described below, given the characteristics of our power plant portfolio. Many of these trends, but not 
all, are positive for our portfolio of power plants:

•  Economic pressures continue to increase for coal-fired power generation as natural gas prices remain low and state 
and federal agencies enact environmental regulations 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. Depending on how the new presidential administration approaches existing and proposed 
rules, older, less efficient fossil-fuel power plants that emit much higher amounts of GHG, SO2, NOX, Hg and acid 
gases, which operate nationwide, but more prominently in the eastern U.S., may need to install expensive air pollution 
controls or reduce or discontinue operations. Any retirements or curtailments could enhance our growth opportunities 
through greater utilization of our existing power plants and development of new power plants. The estimated capacity 
for fossil-fueled plants 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 earn premium compensation for that flexibility; 

11

however,  risks  also  exist  that  renewables  have  the  ability  to  lower  overall  wholesale  power  prices  which  could 
negatively affect us. Significant economic and reliability concerns for renewable generation have been raised, but 
we expect that renewable market penetration will continue, assisted by state-level renewable portfolio standards and 
federal  tax  incentives. The  Consolidated Appropriations Act  which  extended  the  production  tax  credit  for  wind 
through the end of 2016 with gradual decreases thereafter until the tax credit expires completely in 2019 and extended 
the 30% investment tax credit for solar through the end of 2019 with gradual decreases through 2021 after which 
the investment tax credit declines to 10% was enacted in December 2015. Increased renewable penetration has a 
particularly negative effect on inflexible baseload units and may lead to retirement of additional baseload units, 
which would benefit us; however, our energy margin may also decrease due to lower market clearing prices which 
result from the growth of zero marginal cost renewables supply in the market. To the extent market structures evolve 
to appropriately compensate units for providing flexible capacity to ensure reliability, our capacity revenue may 
increase.

•  One  small  but  growing  source  of  competing  renewable  generation  in  some  of  our  regional  markets  (primarily 
California) is customer-sited (primarily rooftop) solar generation. Levelized costs for solar installation have fallen 
significantly over the past several years, aided by federal tax subsidies and other local incentives, and are now in 
some regions lower than customer retail electric rates. To the extent on-site solar generation is compensated at the 
full retail rate (an increasingly controversial policy known as “net energy metering”), rooftop solar installations may 
continue to grow. Should net energy metered solar installations remain at relatively low levels of penetration or net 
energy metering policies be weakened (by rate structure reforms that charge customers fixed amounts regardless of 
the level of electricity consumed, thus lowering the variable portion of the rates), rooftop solar growth might diminish. 
Absent incentives and supportive policies, rooftop solar is currently generally not competitive with wholesale power.

•  The regulators in our core markets remain committed to the competitive wholesale power model, particularly in 
ERCOT, PJM and ISO-NE 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. However, certain states have taken or are 
considering subsidizing or otherwise providing economic support to existing, uneconomic power plants such as 
nuclear power plants. These efforts, if successful, could reduce the number of nuclear unit retirements that would 
result from currently low market prices. 

•  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. Performance standards 
for demand side resources have been made more stringent recently 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, transmission lines and pipelines continue to increase 

in stringency and complexity, resulting in prolonged, expensive development cycles and high capital investments.

We believe many of these trends, but not all, are positive for our existing 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 various risk factors which 

could affect our business. A description of these risk factors is included under Item 1A. “Risk Factors.”

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, the Northeast and Mid-Atlantic, our natural gas-fired power 
plants compete directly with all other sources of power. The EIA estimates that in 2016, 34% of the power generated in the U.S. 
was fueled by natural gas, 30% by coal, 20% by nuclear facilities and the remaining 16% of power generated by hydroelectric, 
fuel  oil,  geothermal  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.  While  the  new  presidential 
administration’s  plans  have  not  yet  been  announced,  existing  and  proposed  regulations  continue  to  target  lower  air  pollutant 

12

emissions such as NOX, SO2, GHG, Hg and acid gases and also limit the use of once-through cooling and some methods of 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 increases 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 and a stable and affordable supply of natural gas, 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 retire. Meanwhile, 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 nuclear energy is currently seen as unlikely to increase in the future. 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. The nuclear projects that are currently under construction in the U.S. are experiencing cost overruns and 
delays. Further, low power prices are challenging the economics of existing nuclear facilities, resulting in the retirement or potential 
retirement  of  certain  existing  nuclear  generating  units  and  triggering  efforts  on  the  part  of  nuclear  power  plant  owners  and 
stakeholders to seek out-of-market subsidies to maintain operations. 

Competition from renewable generation is likely to increase in the future. Federal and state financial incentives and RPS 
requirements continue to foster renewables development. The Consolidated Appropriations Act which extended the production 
tax credit for wind through the end of 2016 with gradual decreases thereafter until the tax credit expires completely in 2019 and 
extended the 30% investment tax credit for solar through the end of 2019 with gradual decreases through 2021 after which the 
investment tax credit declines to 10% was enacted in December 2015. In October 2015, the EPA promulgated the Clean Power 
Plan  which  requires  future  reductions  in  GHG  emissions  from  existing  power  plants  and  provides  flexibility  in  meeting  the 
emissions reduction requirements including adding renewable generation, although the ultimate implementation of this rule is 
uncertain given the change in presidential administration. 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, 
while  subsidized  renewables  growth  is  likely  to  continue,  natural  gas  units  will  likely  be  needed  as  baseload  and  “back-up” 
generation in the long-term.

Retail electricity and natural gas is similarly a commodity-driven business with numerous industry participants. We 
compete against other integrated power companies, regulated utilities, other retail power providers, brokers, trading companies 
including those owned by financial institutions, retail load aggregators, municipalities and cooperatives to supply power and 
power-related products to our customers in major markets in the U.S. and Canada. 

We believe our ability to compete in both wholesale and retail markets 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, efficiency and production 
cost management;

effectively utilize our sales channels to reach our customers;

accurately assess and effectively manage our risks; and

accomplish all of the above with an environmental effect that is lower than the competition and further decreasing 
over time.

 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. Our retail subsidiaries also provide us with a hedging 
outlet for our wholesale power plant portfolio.

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 power and in natural gas, natural 
gas transportation, electric transmission, REC prices, carbon allowance prices in California and the Northeast 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 

13

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 exposure and our hedging activities related to our fuel oil exposure are not material to 
our financial condition, results of operations or cash flows.

We produced approximately 110 billion KWh of electricity in 2016 across North America and consumed approximately 
839 Bcf of natural gas, making us one of the largest producers of electricity and consumers of natural gas in North America. Our 
retail affiliates provided approximately 65 billion KWh to customers in 2016. Our retail portfolio has been established to provide 
an additional source of liquidity for our generation fleet as we hedge retail load from our wholesale generation assets as appropriate. 

The primary power markets in which we conduct our wholesale power operations are California (included in our West 
segment), Texas (included in our Texas segment) and the Northeast and Mid-Atlantic (included in our East segment) which have 
centralized markets for which power demand and prices are determined on a spot basis (day ahead and real time). 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 including our retail affiliates, commercial and industrial wholesale and retail 
end users, financial institutions, power trading and marketing companies, residential end users (through our retail subsidiaries) 
and other third parties. Our retail affiliates conduct business in 20 states including California, Texas, the Mid-Atlantic and Northeast 
where our wholesale power generation fleet is concentrated.

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, retail power sales including through our 
retail affiliates, steam sales, buying and selling standard physical power and natural gas products, buying and selling exchange 
traded instruments, buying and selling environmental and capacity products, natural 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.  
We have economically hedged a portion of our expected generation and natural gas portfolio as well as retail load supply obligations, 
where appropriate, mostly through power and natural gas forward physical and financial transactions including retail power sales; 
however, we currently remain susceptible to significant price movements for 2017 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 estimates and reporting. Additionally, we seek to manage the associated risks through diversification, 
by controlling position sizes, by using portfolio position limits, and by actively managing hedge positions to lock in margin. We 
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.

We have historically used interest rate hedging instruments to adjust the mix between our fixed and variable rate debt. 
To the extent eligible, our interest rate hedging instruments 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.

Seasonality and weather can have a significant effect 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

Subsequent to the completion of the sale of Osprey Energy Center on January 3, 2017 and the retirement of the Clear 
Lake Power Plant on February 1, 2017, we own 80 power plants, including one under construction, with an aggregate generation 
capacity of 25,908 MW and 828 MW under construction. 

Natural Gas-Fired Fleet

Our natural gas-fired power plants primarily utilize two types of designs: 2,260 MW of simple-cycle combustion turbines 
and 22,194 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 fuel 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. Each of our power plants currently in operation is capable of producing power for 
sale to a utility, another third-party end user, our retail customers or an intermediary such as a marketing company. At 15 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 Steam Adjusted Heat Rate for 2016 for the power plants we operate was 7,324 Btu/KWh which results in a power 
conversion efficiency of approximately 47%. The power conversion efficiency is a measure of how efficiently a fossil fuel power 
plant converts thermal energy to electrical energy. Our 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%.

Our  natural  gas  fleet  is  relatively  young  with  a  weighted  average  age,  based  upon  MW  capacities  in  operation,  of 
approximately 16 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 per MWh produced 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: General Electric 7FA, General Electric 
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  13  operating  power  plants  in  northern  California.  Geothermal  power  is 
considered 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 generate power. 
For the past 16 years, our Geysers Assets have reliably generated, on average, approximately six million MWh of renewable power 
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 
of approximately 90% in 2016.

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 14 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 two 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.

17

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 2015. Our evaluation of our geothermal reserves, including our review of any 
applicable independent studies conducted, indicated that our Geysers Assets should continue to supply sufficient steam to generate 
positive cash flows at least through 2073. In reaching this conclusion, our evaluation, consistent with the due diligence study of 
2015, 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 107 leases comprising approximately 29,000 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 2016 is:

• 

• 

• 

26% related to leases with the federal government via the Office of Natural Resources Revenue,

30% related to leases with the California State Lands Commission and

44% 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 relative to the total steam 
generated by our Geysers Assets as a whole.

Our geothermal leases are generally for initial terms varying from five to 20 years and 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

We also have 725 MW of older, less efficient technology at our Edge Moor Energy Center which has conventional steam 
turbine technology. We also have 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,

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)  We suspended operations at our Sutter Energy Center to assess the future of the facility.

(6)  We have entered into an agreement to sell South Point Energy Center. South Point Unit 2 experienced a combustion turbine

(11) 

In accordance with a power purchase agreement, a third party will purchase a 50% ownership interest in this power plant 
upon achieving commercial operation.

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 

21

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 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 either 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. In 2015, our 
emissions of GHG amounted to approximately 50 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 NOx, a precursor of atmospheric ozone and acid rain. 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.

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 96.5% less CO2. There are 15 active geothermal power plants located 
in The Geysers region of northern California. We own and operate 13 of them. We recognize the importance of our Geysers Assets 
and we are committed to extending 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 effect of our operations on water as a 

natural resource:

•  We receive and inject an average of approximately 14 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 
two 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.

•  Three of our power plants (Sutter Energy Center, Otay Mesa Energy Center and Fore River Energy Center) employ 

air cooled condensers for cooling, consuming virtually no water for cooling.

• 

In 12 of our operating natural gas-fired power plants 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 38 million gallons per day of valuable surface and/or groundwater for cooling.

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 have an effect on our business. 
Some of the more significant governmental and regulatory matters that affect our business are discussed below.

Environmental Matters

In November 2016, the United States held elections which resulted in the Republican presidential candidate, Donald 
Trump, being elected as the 45th President of the United States and the Republican Party maintaining control of both houses of 
the U.S. Congress. At this time, we cannot predict the effect the result of the election will have on current or pending environmental 
regulations  promulgated  by  the  EPA.  However,  we  intend  to  continue  to  advocate  for  reasonable  regulations  protecting  the 
environment which positively benefit our competitive market position by recognizing the value of our investments in clean and 
efficient power generation technology.

Federal Air Emissions Regulations

CAA

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. In addition to regulation of air emissions at the federal level, a number of states in which we do business 
have implemented regulations that go beyond current federal environmental requirements. We continue to monitor and actively 
participate in federal and state initiatives which further our environmental and business objectives and where we anticipate an 
effect on our business.

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, 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 

23

 
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. The EPA also regulates emissions of certain pollutants that affect visibility in national parks 
and wilderness areas (“Regional Haze”). Finally, the EPA has begun regulating GHG emissions from various industries, including 
the power sector. 

CAA  regulations  primarily  affect  higher-emitting  units  in  the  national  power  generating  fleet.  Our  commitment  to 
environmental stewardship is reflected in our history of investing in low-emitting power plant technologies. As a result, these 
regulations generally do not have a meaningful, direct adverse effect on our generating fleet, although they may impose significant 
costs on the power industry overall. 

NAAQS — Ozone 

As part of its ongoing CAA obligation to periodically review NAAQS to ensure that air quality is protective of human 
health and the environment, on October 1, 2015, the EPA set a new standard for ground-level of ozone of 70 parts per billion, 
down from the standard set in 2008 of 75 parts per billion. This is significant to the power sector because ground-level ozone is 
a product of complex chemical reactions contributed to by NOx, which are one of the primary emissions of concern from power 
plants. 

Air quality in the Houston area, where seven of our power plants are located, has improved over the last two decades. 
As a result, the Houston area was determined by the EPA to be attaining the 1-hour ozone standard, effective November 19, 2015, 
and the 1997 8-hour ozone standard, effective January 29, 2016. The Houston area remains in nonattainment relative to the 2008 
ozone standard, and in fact, was downgraded in overall status relative to that standard on December 14, 2016. The area’s status 
has not yet been determined for the 2015 ozone standard, but is likely to be in nonattainment as well, which could lead to further, 
more stringent regulation of NOx emissions from mobile sources and a number of industry sources, particularly the power industry.

Pursuant to authority granted under the CAA, the TCEQ adopted regulations to attain the earlier NAAQS for ozone 
including 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. Due to the more stringent ozone standard promulgated in 2015, allowable NOx 
emissions under this program could be reduced at some point in the future, which could cause us to incur additional compliance 
costs. However, we cannot estimate such costs until such program changes are proposed and finalized.

Mercury and Air Toxics Standards

On February 16, 2012, the EPA promulgated the NESHAP 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 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 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.  MATS  required  existing  coal-fired  units  without 
emissions controls 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 to comply 
with MATS, which many sources have successfully requested. Further, 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. Very few of these “second year” extensions have been issued. None of our facilities are subject to MATS.

MATS has been heavily litigated since its promulgation. On June 13, 2016, the U.S. Supreme Court denied a request to 
stay MATS which effectively ends the legal challenges to stop MATS from being implemented. On April 25, 2016, the EPA 
published in the Federal Register the final, revised “necessary and appropriate” determination to address the narrow issue for 
which the U.S. Supreme Court, and subsequently the D.C. Circuit, had remanded the MATS rule to the EPA for further action. 
This effectively addresses previous litigation related to MATS, although this action itself is now the subject of further litigation.

24

 
 
Multi-Pollutant Programs — CSAPR

Pursuant to authority granted under the CAA, the EPA has promulgated a series of regulations to reduce region-wide 
emissions of NOx and SO2 in the eastern U.S. The most recent of these regulations is CSAPR, which became effective on January 
1, 2015. The purpose of CSAPR and predecessor regulations is to facilitate attainment of ozone and fine particulates NAAQS. 
These regulations have required reductions of SO2 emissions in affected states by over 70%, and NOX emissions by over 60% 
from 2003 levels by 2015 through Cap-and-Trade programs. Further region-wide reductions in NOx and SO2 will be required by 
a CSAPR update published on October 26, 2016. 

CSAPR and prior regional multipollutant regulations have been heavily litigated since their inception beginning in 2002. 
This litigation has played out with the regional program largely remaining in place as written, with some modifications required 
by the courts. Specifically, the court vacated the CSAPR SO2 budgets for four states, including Alabama and Texas, and remanded 
the CSAPR SO2 program for those states to the EPA for correction. This action didn’t affect the CSAPR SO2 program in other 
states, or the CSAPR NOx program in these four states.

MATS and CSAPR primarily affect coal-fired power plants; therefore, these rules do not directly affect our power plants. 

Regional Haze

The EPA first issued the Regional Haze rule in 1999, with a focus on emissions of SO2, NOx, and particulate matter, 
particularly PM2.5. The Regional Haze program includes two major components: demonstration of Reasonable Further Progress, 
and installation of Best Achievable Retrofit Technology (“BART”). States submit State Implementation Plans (“SIP”) to the EPA 
for approval. These SIPs delineate all of the relevant emission controls programs in the state, and demonstrate that the state is 
making reasonable progress toward the Regional Haze program visibility goals. In addition, states must require the installation of 
a minimum level of controls that are considered cost-effective on coal- and oil-fired power plants within the state. In the eastern 
U.S., regional NOx and SO2 programs like CSAPR are relied upon in Regional Haze SIPs to achieve much of the required emission 
reductions, and are also allowed by EPA policy to substitute for the installation of BART. If the EPA does not approve a SIP, it 
may instead issue a Federal Implementation Plan (“FIP”), which will specify the control requirements for sources in a state. On 
January 4, 2016, the EPA finalized its rule partially disapproving Texas’ Regional Haze SIP and imposing a FIP that requires 
installation of SO2 emission controls at several coal-fired power plants in Texas. Litigation ensued, and the SIP disapproval and 
FIP are currently stayed by court action. Because the CSAPR SO2 program for Texas was vacated, the requirement to install BART 
for SO2 emissions is now applicable. Accordingly, the EPA proposed a FIP for BART controls on December 9, 2016. This FIP 
would require installation or upgrade of SO2 controls on 16 units at seven coal-fired power plants in Texas. While the ultimate 
outcome of these actions will not directly affect our fleet, it does have the potential to affect the power market in Texas because 
the affected facilities would either have to further reduce emissions or retire, although the ultimate implementation of this rule is 
uncertain given the change in presidential administration.

GHG Emissions

Over the past several years, the EPA has proposed and issued rules related to GHG emissions within the power sector.  
The new presidential administration, however, has not indicated support for some of these rules, including, most notably, the Clean 
Power Plan. 

The EPA’s regulation of GHG in response to the 2007 decision of the U.S. Supreme Court in Massachusetts v. EPA has 
been controversial and heavily litigated at every step of the regulatory process. Within the power industry, the EPA first proposed 
to regulate GHG emissions through the PSD and Title V programs, the two major permitting programs of the CAA. 

These permitting rules were the subject of more than 60 petitions for review by industry and the states. The U.S. Supreme 
Court ultimately heard the case, and on June 23, 2014, rejected the PSD and Title V permitting rules in part but upheld the EPA’s 
authority to impose GHG limits on large new or modified sources if such sources were required to obtain permits for other pollutants. 
Our clean portfolio and additions thereto already meet the technology required by these rules. Therefore, we believe we are well-
positioned to benefit from this regulatory development. 

In January 2014, the EPA proposed New Source Performance Standards (“NSPS”) for GHG emissions from new power 
plants. In June 2014, the EPA proposed the Clean Power Plan which required a reduction in GHG emissions from existing power 
plants of 30% from 2005 levels by 2030. In June 2014, the EPA also proposed GHG NSPS provisions for modified and reconstructed 
sources. 

On October 23, 2015, the EPA published the final NSPS for GHG emissions from new, modified and reconstructed power 
plants and the Clean Power Plan. The final Clean Power Plan requires a reduction in GHG emissions from existing power plants 
of 32% from 2005 levels by 2030. Litigation challenging the Clean Power Plan has been filed by at least 25 states and a number 

25

 
 
 
of industry opponents. In addition to litigation challenging the rule on the merits, several motions for stay of the rule and for 
expedited consideration of the appeals were also filed. On February 9, 2016, the U.S. Supreme Court issued a stay of the Clean 
Power Plan until the D.C. Circuit issues a ruling on the merits and through final determination in any further appeal to the U.S. 
Supreme Court from the D.C. Circuit decision. Oral arguments were held on September 27, 2016 in the D.C. Circuit. Overall, we 
support the Clean Power Plan and believe we are well positioned to comply with its provisions. We expect the Clean Power Plan 
to  be  beneficial  to  Calpine,  although  the  ultimate  implementation  of  this  rule  is  uncertain  given  the  change  in  presidential 
administration.

In addition to federal GHG rules, several states and regional organizations have developed state-specific or regional 
initiatives to reduce GHG emissions through mandatory programs. The most advanced programs include California’s suite of 
GHG policies promulgated pursuant to AB 32, including its Cap-and-Trade program, and RGGI in the Northeast. The evolution 
of these programs could have a material effect on our business.

In both of these programs, a cap is established defining the maximum allowable emissions of GHGs emitted by sources 
subject to the program. Affected sources are required to hold one allowance for each ton of CO2 emitted (and, in the case of 
California’s program, other GHGs) during the applicable compliance period. Both programs also contain provisions for the use 
of qualified offsets in lieu of allowances. Allowances are distributed through auctions or through allocations to affected companies. 
In addition, there are functional secondary markets for allowances. We obtain allowances in a variety of ways, including participation 
in auctions, as part of PPAs, and through bilateral or exchange transactions.

State Air Emissions Regulations

California: GHG - Cap-and-Trade Regulation

AB 32 requires the state to reduce statewide GHG emissions in reference to 1990 levels. To meet this mandate, the CARB 
has promulgated a number of regulations, including the Cap-and-Trade Regulation and Mandatory Reporting Rule, which took 
effect on January 1, 2012. These regulations have since been amended by the CARB several times.

Under the Cap-and-Trade Regulation, the first compliance period for covered entities like us began on January 1, 2013 
and ended on December 31, 2014. The second and third compliance periods, wherein the program applies to a broader scope of 
entities, including transportation fuels and natural gas distribution, run through the end of 2017 and 2020, respectively. Covered 
entities must surrender compliance instruments, which include both allowances and offset credits, in an amount equivalent to their 
GHG emissions.

The California Cap-and-Trade market has been linked to the GHG Cap-and-Trade market in Québec since 2014. Joint 
auctions of allowances issued by both jurisdictions, which can be used interchangeably, are held quarterly. The Canadian province 
of Ontario also began implementing its own Cap-and-Trade Program in 2017, with the goal of linking with the California- Québec 
market as soon as 2018. The Governor of New York has also previously announced that New York would explore the possibility 
of linking RGGI, a carbon market operating in nine northeastern states, with the California-Québec and Ontario markets.

 In addition to the 2020 goal, California also has a long-term goal established by a 2005 executive order to reduce statewide 
GHG emissions to 80% below 1990 levels by 2050. Additionally, in 2015, California Governor Jerry Brown issued an executive 
order that establishes an interim GHG reduction target of 40% below 1990 levels by 2030 and orders the CARB to update its 
Climate Change Scoping Plan to express the 2030 target in tons of GHG emissions. 

The 2030 target was enacted into law on September 8, 2016, when Governor Brown signed Senate Bill 32 (“SB 32”). 
SB 32 amends AB 32 by requiring the CARB to ensure that statewide GHG emissions are reduced to at least 40% below 1990 
levels by 2030. SB 32 was joined to companion legislation, Assembly Bill 197 (“AB 197”), which Governor Brown also signed 
into law on September 8, 2016. AB 197 amends AB 32 to specify that CARB must prioritize emission reduction rules and regulations 
that result in direct emission reductions from sources of GHG emissions. While the author of AB 197 confirmed in an accompanying 
statement that AB 197 does not preclude the CARB from adopting market-based compliance mechanisms pursuant to AB 32, 
neither SB 32, nor AB 197, expressly affirms the CARB’s authority to extend the Cap-and-Trade Regulation beyond 2020. 

The CARB has proposed amendments to the Cap-and-Trade Regulation that would extend the program beyond 2020 
and add provisions so that its implementation can be relied upon to satisfy the requirements of the federal Clean Power Plan 
regulation. Due to uncertainty created by litigation currently pending at the California Court of Appeals challenging the Cap-and-
Trade Regulation’s auctions as an unlawful tax and potential claims that might be brought challenging the CARB’s adoption of 
the proposed amendments to the Cap-and-Trade Regulation, Governor Brown proposed as part of his release of the proposed 
budget on January 10, 2017, legislation confirming the CARB’s authority to continue implementing the Cap-and-Trade Program’s 
auctions. The Governor previously announced that, if such legislation should not pass in 2017, he would seek authorization for 
continuation of the Cap-and-Trade Program through the voter initiative process.

26

 
The CARB is currently developing an update to its AB 32 Scoping Plan, laying out the strategies California will utilize 
to  achieve  the  2030  target  established  by  SB  32,  including  continuation  of  the  Cap-and-Trade  Program.  The  CARB  is  also 
considering two alternatives to its proposed Scoping Plan scenario, one which would not include continuation of the Cap-and-
Trade Program and one which would rely upon implementation of a carbon tax in lieu of the Cap-and-Trade Program.  

Overall,  we  support AB  32  and  expect  the  net  effect  of  the  Cap-and-Trade  Regulation  to  be  beneficial  to  Calpine, 
particularly by increasing the appeal of our Geysers Assets. We also believe we are well positioned to comply with the Cap-and-
Trade Regulation.

Northeast GHG Regulation: RGGI

Nine states in the Northeast participate in RGGI, a Cap-and-Trade program, which affects our power plants in Maine, 

Massachusetts, New Hampshire, New York and Delaware (together emitting about 5.4 million tons of CO2 annually).

We receive 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 effect from RGGI, given the efficiency of our power plants in RGGI states.

Consistent with the original memorandum of understanding under which the states created RGGI, the overall success of 
the RGGI program was reviewed in 2013, and is in the process of being reviewed again. The 2013 program review led to a number 
of changes, most significant of which was a reduction of the aggregate RGGI cap from 165 million tons to 91 million tons, slightly 
less than RGGI-wide emissions in 2012. We do not expect any material effect to our business from this change in regulations. At 
this time, it is not possible to predict the outcome of the current program review.

Massachusetts: Global Warming Solutions Act

On December 16, 2016, the Massachusetts Department of Environmental Protection proposed regulations that would 
impose new GHG limits on power plants and other sources. These regulations are notable because they are structured as declining 
caps on emissions from regulated facilities with a limited allowance trading program. We are engaged in the rulemaking process, 
but are unable to predict the outcome of these regulations at this time. Although we view the regulations as proposed as likely to 
result in market distortions impeding the efficient operation of both power and emissions markets, we believe that we will be able 
to comply with its provisions if this regulation is finalized.

Maryland: Greenhouse Gas Emissions Reduction Act

On April 4, 2016, the Governor of Maryland  signed into law the Reauthorization  of the Greenhouse Gas Emissions 
Reduction Act which builds on the 2009 Greenhouse Gas Emissions Reduction Act that required a 25% reduction of GHG emissions 
from 2006 levels by 2020. The legislation requires the Maryland Department of the Environment (“MDE”), in coordination with 
other Maryland agencies, to develop plans, adopt regulations and implement programs to reduce GHGs. The legislation includes 
several “off ramps” designed to protect manufacturers and electric generators. Under the bill, the State must demonstrate MDE’s 
compliance plans will have a positive effect on Maryland’s economy and will protect existing manufacturing jobs.

Ontario: Climate Change Mitigation and Low-Carbon Economy Act

Ontario is implementing a new GHG law with an associated Cap-and-Trade program which became effective January 1, 
2017. This program requires power generators to either acquire related CO2 allowances on their own behalf or, in most cases, the 
natural gas pipeline supplying the power generation facility will procure such allowances and bill the power generator in the form 
of a CO2 surcharge on its natural gas transportation invoice. Greenfield LP has a long-term Clean Energy Supply Contract with 
the IESO, successor to the Ontario Power Authority. We believe the contract contemplates and provides for the full pass-through 
of CO2 cost, although there have been communications from the IESO which indicate an alternative view. Greenfield LP is currently 
negotiating to remedy this matter. On a related note, Whitby has a PPA with the Ontario Electricity Financial Corporation, successor 
to Ontario Hydro. Whitby is also seeking to recover related CO2 cost being applied to its natural gas transportation invoice. As 
this issue is ongoing, we cannot predict the ultimate effect on our financial condition, results of operations or cash flows.

Other Environmental Regulations

RPS

We are subject to an RPS in multiple states in which we do business. 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.

27

 
 
 
 
California RPS

California’s RPS requires retail power providers to generate or procure 33% and 50% of the power they sell to retail 
customers from renewable resources by 2020 and 2030, respectively, with intermediate targets leading up to 2020 and 2030. 
Behind-the-meter solar generally does not count towards California’s RPS requirements. Under California’s RPS, there are limits 
on different “buckets” of procurement that can be used to satisfy the RPS. Load-serving entities must satisfy a growing fraction 
of their compliance obligations with renewable power from resources located in California or delivered into California within the 
hour, such as our Geysers Assets. While the RPS generally depresses wholesale energy prices, the intermittency of many renewable 
resources raises operational flexibility challenges that present opportunities for natural gas-fired generation to provide capacity 
and ancillary services products.

Other States

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 an enforceable RPS in the future. Our retail subsidiaries 
operate in states that have an RPS in place and are required to procure a certain amount of power from renewable sources or 
purchase renewable energy credits in order to comply with the RPS requirements.

Miscellaneous

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 wastewater and the use of water, but can also 
include wetlands protection and preservation, protection of 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.

Clean Water Act 

The federal Clean Water Act establishes requirements relating to the discharge of pollutants into waters of the U.S., 
including  from  cooling  water  intake  structures. We  are  required  to  obtain  wastewater  and  storm  water  discharge  permits  for 
wastewater and runoff, respectively, for some of our power plants. We are subject to the requirements for cooling water intake 
structures at one of our power plants. In addition, we are required to maintain spill prevention control and countermeasure plans 
for some of our power plants. We believe that we are in compliance with applicable discharge requirements of the Clean Water 
Act.

In California, the EPA delegates the implementation of Section 316(b) to the California State Water Resources Control 
Board (“SWRCB”). The SWRCB has promulgated its own once-through cooling policy that establishes a schedule for once-
through cooling units to install closed-cycle wet cooling (i.e., 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 effect 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 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 compliance with RCRA and related state laws.

28

 
 
 
 
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.

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. In general, these state law-related claims have been unsuccessful in assigning tort liability 
for GHG emissions to power generators. We cannot predict the outcomes of these cases or what effect such cases, if successful, 
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 the 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. The 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.

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 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 approximately $1.2 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.

Pursuant to EPAct 2005, NERC has been certified by the FERC as the Electric Reliability Organization to develop and 
enforce reliability standards and critical infrastructure protection standards, which protect the bulk power system against potential 
29

 
disruptions from cyber and physical security breaches. The NERC standards are applicable throughout the U.S. and 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.  The  critical  infrastructure  protection  standards  focus  on 
controlling access to critical physical and cybersecurity assets, including supervisory control and data acquisition systems for the 
electric grid. Compliance with these standards is mandatory. Monetary penalties of approximately $1.2 million per day per violation 
may be assessed for violations of the reliability and critical infrastructure protection standards. 

The composition of the FERC commissioners will change as a result of the new presidential administration. Cheryl 
LaFleur, a Democrat, was recently named Acting Chairman of the FERC, replacing Norman Bay, another Democrat.  Shortly after 
the LaFleur announcement, Norman Bay announced that he would resign from the FERC, effective February 3, 2017.  This leaves 
only two commissioners at the FERC which results in a lack of quorum that is required for the commissioners to issue orders. It 
is expected that Chairman LaFleur will delegate authority to the FERC staff to manage some issues, but it is expected that much 
of the FERC’s work will be delayed until additional commissioners are named by the President and confirmed by the U.S. Senate. 
With new commissioners, the FERC’s focus and direction will likely change, resulting in possible changes in the FERC’s policies 
and rules in the future, but we cannot predict at this time the effect those changes may have on our business.  

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. 
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.

Power Regions

The following is a brief overview of the most significant regulatory issues affecting our business in our core power 
regions – CAISO, ERCOT, PJM, ISO-NE and NYISO. The CAISO market is in our West segment. The ERCOT market is in our 
Texas segment. The PJM, ISO-NE and NYISO markets are in our East segment. 

CAISO

The majority of our power plants in our West segment are located in California, in the CAISO region. We also own one 

power plant in Arizona and one in 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. 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. 

The CPUC and CAISO continue to evaluate capacity procurement policies and products for the California power market. 
With the expectation of significant increases in renewables, both entities are evaluating the need for operational flexibility, including 
the ability to start and ramp quickly as well as the ability to operate efficiently at low output levels or cycle off. We are an active 
participant in these discussions and support products and policies that would provide appropriate compensation for the required 
attributes. As these proceedings are ongoing, we cannot predict the ultimate effect on our financial condition, results of operations 
or cash flows, although we believe our fleet offers many features that can, and do, provide operational flexibility to the power 
markets.

In July 2016, we filed a protest with the FERC in response to a complaint filed against the CAISO on June 17, 2016, by 
the owner of a natural gas-fired power plant located in Kern County, California (“La Paloma”). Our protest requested the FERC 
to reject the relief sought in the complaint as a one-off solution to a larger problem and, rather, to convene a technical conference 
to consider whether the California wholesale power market allows modern, efficient natural gas-fired power plants that are needed 
for reliability and flexibility to recover their costs, including a return of, and on, capital and to consider necessary changes to the 
market structure to ensure revenue adequacy. On October 3, 2016, the FERC denied our request for a technical conference but 
encouraged the CAISO to continue an investigation into possible compensation for generation units that are needed but otherwise 
uneconomic to operate. The CAISO is increasingly concerned with the premature retirement of uneconomic generation resources. It 
is evaluating the viability of units it deems at risk of retirement in local, reliability constrained areas through its transmission 

30

planning process. It is also considering modifications to the review and approval of compensation for units threatened by economic 
retirement, but needed for reliability under the Capacity Procurement Mechanism portion of its tariff.

ERCOT

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. In ERCOT, there is a market offer price cap for energy and capacity services 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 is considering changes regarding its approach to resource adequacy, including price formation and scarcity 
pricing as operating reserves decline. ERCOT successfully launched the Operating Reserve Demand Curve (“ORDC”) functionality 
on June 1, 2014. This application produces a price “adder” to the clearing price of energy that increases as reserve capacity declines. 
The  PUCT  requested  a  review  of  the  effectiveness  of  the  ORDC  and  requested  input  from  ERCOT  and  market  participants, 
including any recommendations to improve the ORDC. The PUCT continues to consider the appropriate reliability standard that 
should be used to set ERCOT’s planning reserve margin. As these proceedings are ongoing and the timing of these changes is 
uncertain, we cannot predict the ultimate effect on our financial condition, results of operations or cash flows.

PJM

PJM operates wholesale power markets, a locationally based energy market, a forward capacity market and ancillary 
service markets. PJM also performs transmission planning and operation for the region. The rules and regulations affecting PJM 
power markets and transmission are subject to change at any time.

PJM experienced several unusual cold weather events during January 2014. PJM maintained system reliability, but the 
system was challenged. In order to address some of these challenges, PJM filed proposed capacity market rule changes in December 
2014 which include much stronger performance incentives and more significant penalties for failure to perform during emergency 
power system conditions. The FERC approved PJM’s proposed changes with minor alterations. Additional risk premiums associated 
with the capacity market rule changes are expected to produce commensurately higher capacity market prices and appear to have 
done so to date. Several entities have appealed the FERC’s orders approving PJM’s capacity market rule changes. The appellate 
case is pending. We support PJM’s capacity market rule changes and believe that, overall, they enhance the competitiveness and 
reliability of the PJM power market.

In Ohio, after FirstEnergy Corp. (“FE”) submitted various proposals to the Public Utility Commission of Ohio (“PUCO”) 
to enhance its generation company revenue, the PUCO approved a Distribution Modernization Rider (“DMR”) for the FE utilities 
that results in approximately $200 million per year for three years of ratepayer subsidized payments to FE. The PUCO’s order 
approving the DMR has been challenged by several parties. Appeals to the Ohio Supreme Court remain pending. In a related 
move, the Ohio Utilities, led by American Electric Power, Inc. and FE, have indicated their intentions to advocate for some form 
of re-regulation in this year’s legislative session which began on January 3, 2017. Re-regulation will require enabling legislation, 
and to date no proposal has been made public by the utilities. 

Over significant opposition, the Illinois legislature voted to approve an out-of-market nuclear subsidy scheme put forward 
by Exelon Corporation (“Exelon”). Zero emission credits are to be paid to Exelon’s nuclear units beginning with the planning year 
commencing June 1, 2017. It is expected that the legislation will be challenged in court, although we cannot predict the outcome 
of any possible litigation. If left unchecked, we believe these subsidies will adversely affect the power markets in PJM by artificially 
suppressing prices.

ISO-NE

 We have three power plants in our East segment located in Massachusetts, Maine and New Hampshire, all of which 
participate in the regional wholesale market in which ISO-NE is the RTO. ISO-NE has broad authority over the day-to-day operation 
of the transmission system and, among other responsibilities, operates a day-ahead and real-time wholesale energy market, a 
forward capacity market and an ancillary services market.

ISO-NE has requested that the FERC approve a revised Cost of New Entry (“Net CONE”) parameter for Forward Capacity 
Auctions beginning in 2018 which is lower than the previous Net CONE. The potential effect on our business is currently unknown.

31

 
In 2016, Massachusetts passed legislation mandating the issuance of Requests for Proposals for up to 2,800 MW of 
renewable generation including hydro and offshore wind that would be procured under long-term contracts. Massachusetts is also 
considering the procurement of up to 600 MW of storage resources under the provisions of the 2016 energy bill. As the provisions 
of the legislation are still being finalized, we cannot predict the ultimate effect on our financial condition, results of operations or 
cash flows.

NYISO

We have five power plants in our East segment located in New York where NYISO is the RTO which 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.

On August 1, 2016, the New York State Public Service Commission  (“PSC”) approved the Clean Energy Standard which 
requires 50% of the state’s generation to be produced by renewable resources by 2030. In addition, the Clean Energy Standard 
provides for out-of-market financial subsidies for some of the state’s existing nuclear generation facilities. In October 2016, a 
group of generators and our trade association, the Electric Power Supply Association, filed a lawsuit in federal court challenging 
the PSC’s ruling on constitution grounds. We cannot predict the outcome of that litigation, but if left unchecked, we believe these 
subsidies will adversely affect the power markets in NYISO by artificially suppressing prices.

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 affected 
by federal regulation of natural gas transportation and sales. Furthermore, one of our natural gas transportation pipelines in Texas 
is subject to dual jurisdiction by the FERC and the Texas Railroad Commission. This pipeline is an intrastate pipeline within the 
meaning  of  Section 2(16)  of  the  Natural  Gas  Policy Act  (“NGPA”).  FERC  regulates  the  rates  charged  by  this  pipeline  for 
transportation services performed under Section 311 of the NGPA, and the Texas Railroad Commission regulates the rates and 
services provided by this pipeline as a gas utility in Texas. We also own a pipeline in Texas that is subject to the Texas Railroad 
Commission regulation as a Texas gas utility. 

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.

The FERC has civil penalty authority for violations of the Natural Gas Act (“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 approximately $1.2 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). 

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 

32

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.

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 effect 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 
expect to successfully implement any new applicable requirements.

EMPLOYEES

At December 31, 2016, we employed 2,372 full-time employees, of whom 184 were represented by collective bargaining 
agreements. Two collective bargaining agreements, representing a total of 44 employees, will expire within one year. We have 
never experienced a work stoppage or a strike.

Item 1A. Risk Factors

Commercial Operations

Our financial performance is affected 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:

• 

• 

• 

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;

•  weather conditions, particularly unusually mild summers or warm winters in our market areas;

• 

• 

• 

• 

• 

• 

• 

• 

• 

quarterly and seasonal fluctuations;

an economic downturn which could negatively affect demand for power;

changes in the supply of commodities, including but not limited to coal, natural gas and fuel oil;

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 other environmental allowance products; 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, RTOs 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;

33

• 

• 

• 

• 

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 affect 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. As a result, we are unable to accurately predict 
the effect that our risk management decisions may have on our quarterly and annual financial results.

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 risks related to commodity price movements, deviations in weather and 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 or customer 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.

In addition, we have various internal policies and procedures designed to monitor hedging activities and positions. These 
policies and procedures are designed, in part, to prevent unauthorized purchases or sales of products by our employees. We cannot 
assure, however, that these steps will detect and prevent all violations of our Risk Management Policy, particularly if deception 
or other intentional misconduct is involved. A significant policy violation that is not detected could result in a material financial 
loss for us.

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

us.

Our wholesale counterparties, retail customers and suppliers 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 affect our business and create more volatility in our earnings. 
Additionally,  these  conditions  may  cause  our  counterparties  or  customers  to  seek  bankruptcy  protection  under  Chapter 11  or 
liquidation under Chapter 7 of the U.S. 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 in the power generation industry 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. 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.

34

Other companies we compete with may have greater liquidity, greater access to credit and other financial resources, lower 
cost structures, greater ability to incur losses, longer-standing relationships with customers, greater potential for profitability from 
ancillary services or greater flexibility in the timing of their sale of generation capacity and ancillary services than we do.

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 or customer and/or may 
allow the counterparty or customer to seek liquidated damages.

The situations that could allow a counterparty or customer 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 non-contracted 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 
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.

Our retail subsidiaries may experience customer attrition or may not be able to originate new business at the same levels 

as in the past which could adversely affect our performance.

There is extensive competition in the retail power markets in which our retail subsidiaries operate. Competitors may offer 
lower prices or other incentives which may attract customers away from our retail subsidiaries. We may also face competition 
from a number of other energy service providers, other energy industry participants, or nationally branded providers of consumer 
products and services who may develop business that will compete with our retail subsidiaries.

The introduction or expansion of competing technologies for power generation and demand-side management tools could 

adversely affect our performance.

The power generation business has seen a substantial change in the technologies used to produce power. With federal 
and state incentives for the development and production of renewable sources of power, we have seen market penetration of 
competing technologies, such as wind, solar, and commercial-sized power storage. Additionally, the development of demand-side 
management tools and practices can effect peak demand requirements for some of our markets at certain times during the year. The 
continued development of subsidized, competing power generation technologies and significant development of demand-side 
management tools and practices could alter the market and price structure for power and negatively affect our financial condition, 
results of operations and cash flows.

35

 
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 which 
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 accrue 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 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 affect 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:

36

• 

• 

• 

• 

• 

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.

Additionally, the PJM power market has recently experienced an increase in natural gas-fired generation assets that supply 
electricity to the area. As a result, there has been a corresponding increase in the need for natural gas transmission assets to supply 
the generation assets with fuel to generate power. When extreme cold temperatures rapidly increase the demand for natural gas 
used for residential heating, it can also create constraints on natural gas pipelines that serve power generation assets. When these 
conditions exist, it could interrupt the fuel supply to our natural gas-fired power plants in the PJM power market, although some 
of our natural gas-fired power plants in this region are dual-fuel and benefit from the ability to operate on both natural gas and 
fuel oil.

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;

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

37

• 

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 effect on 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, including weather-related events, or acts of terrorism 
(including cyber attacks), could damage our power plants or our corporate offices or cause a loss of system load and may affect 
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 and a persistent risk of wildfires, such as the September 2015 wildfire incident at our Geysers Assets in Lake 
and Sonoma Counties, California, affecting five of our power plants in the region. More significant seismic disturbances are 
possible. In addition, other areas in which we operate, particularly in Texas and the Southeast, experience tornados and hurricanes. 
Operations at our corporate offices in Houston, Texas could be substantially affected by a hurricane. Any significant loss of system 
load resulting from a weather-related event could negatively affect our wholesale business and retail subsidiaries. Such events 
could damage or shut down our power plants, power transmission or the fuel supply facilities upon which our wholesale business 
and retail subsidiaries are 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 to our power plants 
or disruptions to our wholesale and retail operations due to natural disasters.

In addition to physical damage to our power plants, the risk of future terrorist activity (including cyber attacks) 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.

Our business, financial condition and results of operations could be adversely affected by strikes or work stoppages by 

unionized employees or by our inability to replace key employees.

Approximately 8% of our employees are subject to collective bargaining agreements. 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. 

In addition, 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.

38

We  depend  on  computer  and  telecommunications  systems  we  do  not  own  or  control  and  failures  in  our  systems  or  a 
cybersecurity attack or breach of our IT systems or technology could significantly disrupt our business operations or result in 
sensitive customer information being compromised which would negatively materially affect our reputation and/or results of 
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. We also 
rely on software systems owned and operated by third parties, such as ISOs and RTOs, to be functioning in order to be able to 
transmit the electricity produced by our power plants to our customers. It is possible we or a third party that we rely on could incur 
interruptions from a loss of communications, hardware or software failures, a cybersecurity attack or a breach of our IT systems 
or technology, computer viruses or malware. We believe that we have positive relations with our 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 to our information systems or any of those operated by a third party that we rely on could 
significantly disrupt our business operations.

A cyber attack of our systems or networks that impairs our information technology systems could disrupt our business 
operations and result in loss of service to customers. We have a comprehensive cybersecurity program designed to protect and 
preserve the integrity of our information technology systems. We have experienced and expect to continue to experience actual 
or attempted cyber attacks of our IT systems or networks; however, none of these actual or attempted cyber attacks has had a 
material effect on our operations or financial condition.

Additionally, our retail subsidiaries require access to sensitive customer information in the ordinary course of business. 
If a significant data breach occurred, the reputation of our retail subsidiaries may be adversely affected, customer confidence may 
be diminished, or our retail subsidiaries may be subject to legal claims, any of which may contribute to the loss of customers and 
have a material adverse effect on our retail subsidiaries.

Capital Resources; Liquidity

We have substantial liquidity needs and could face liquidity pressure.

As of December 31, 2016, our consolidated debt outstanding was $12.2 billion, of which approximately $8.9 billion was 
outstanding under our Senior Unsecured Notes, First Lien Term Loans and First Lien Notes. In addition, we had $991 million
issued in letters of credit and our pro rata share of unconsolidated subsidiary debt was approximately $130 million. Although we 
significantly extended our maturities during the last several years, 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. 

We  also  have  exposure  to  many  different  financial  institutions  and  counterparties  including  those  under  our  Senior 
Unsecured  Notes,  First  Lien  Term  Loans,  First  Lien  Notes,  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 
default  under  a  financing  agreement.  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 indebtedness could adversely affect our financial health and limit our operations.

Our 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;

39

• 

• 

• 

• 

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.

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 Senior Unsecured Notes, First Lien Term Loans, First Lien Notes, Corporate Revolving Facility, CCFC Term Loans  
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 Senior Unsecured Notes, First Lien Term Loans, First Lien Notes, Corporate Revolving Facility, 
CCFC Term Loans 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;

40

• 

• 

• 

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

engage in certain business activities; and

enter into certain transactions with our affiliates.

Our Senior Unsecured Notes, First Lien Term Loans, First Lien Notes, Corporate Revolving Facility, CCFC Term Loans 
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 Senior Unsecured Notes, First Lien Term 
Loans, First Lien Notes, Corporate Revolving Facility, CCFC Term Loans 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 affect 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.

There are a number of factors that rating agencies evaluate to arrive at credit ratings for us and our subsidiaries, including 
regulatory framework, ability to recover costs and earn returns, diversification, financial strength and liquidity. If one or more 
rating agencies downgrade us, borrowing costs would increase, the potential pool of investors and funding sources would likely 
decrease, and cash or letter of credit collateral demands may be triggered by the terms of a number of commodity contracts, leases 
and other agreements.

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 affect 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 affect our liquidity.

These letter of credit and cash collateral requirements increase our cost of doing business and could have an adverse 
effect 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, 2016, we had $991 million issued 
in letters of credit under our Corporate Revolving Facility and other facilities, with $1.3 billion 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 with the assets subject to 
liens under our First Lien Notes, First Lien Term Loans and Corporate Revolving Facility.

41

Additionally, changes in market regulations can increase the use of credit support and collateral.

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 Term Loans, 
First Lien Notes 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 Term Loans, First Lien Notes 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,  2016,  our  subsidiaries  had 
approximately $1.6 billion in debt from our CCFC subsidiary and approximately $1.6 billion in secured project financing from 
other subsidiaries, which are effectively senior to our First Lien Term Loans, First Lien Notes and Corporate Revolving Facility. 

42

We may incur additional project financing indebtedness in the future, which will be effectively senior to our other secured and 
unsecured debt.

Governmental Regulation

Federal tax incentives and regulations, existing and proposed state RPS and energy efficiency standards, as well as economic 

support for renewable sources of power under federal or state legislation could adversely affect our operations.

Renewables have the ability to take market share from us and to lower overall wholesale power prices which could 
negatively affect us. The Consolidated Appropriations Act which extended the production tax credit for wind through the end of 
2016 with gradual decreases thereafter until the tax credit expires completely in 2019 and extended the 30% investment tax credit 
for solar through the end of 2019 with gradual decreases through 2021 after which the investment tax credit declines to 10% was 
enacted in December 2015. In October 2015, the EPA promulgated the Clean Power Plan which requires future reductions in GHG 
emissions from existing power plants and provides flexibility in meeting the emissions reduction requirements including adding 
renewable  generation  (although  ultimate  implementation  of  this  rule  has  come  into  question  due  to  the  change  in  the  EPA 
administration). California has a RPS in effect and in 2015 enacted legislation requiring implementation of a 50% RPS by 2030. 
A number of additional states, including Maine, 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 more robust RPS in states in which we are active, coupled with federal tax incentives, 
would likely initially drive up the number of wind and solar resources, increasing power supply to various markets which could 
negatively affect the dispatch of our natural gas-fired power plants, primarily in Texas and California.

Similarly, several states 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 affect the dispatch of our natural gas-fired power plants, primarily in Texas and California.

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

could have an adverse effect 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). 

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

We have a significant presence in the major competitive power markets for California, Texas and the Northeast and Mid-
Atlantic regions of the U.S. While these markets are largely deregulated, 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 affected.

State legislative and regulatory action could adversely affect our competitive position and business.

Certain states have taken or are considering taking anticompetitive actions by subsidizing or otherwise providing economic 
support to existing, uneconomic power plants in a manner that could have an adverse effect on the deregulated power markets. We 
are actively participating in many of the legislative, regulatory and judicial processes challenging these actions at the state and 
federal levels. If these anticompetitive actions are ultimately upheld and implemented, they could adversely affect capacity and 
energy prices in the deregulated electricity markets which in turn could have a material negative effect on our business prospects 
and financial results.

Existing and future anticipated GHG/Carbon and other environmental 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.

43

Currently, nine states in the Northeast are required to comply with 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 including transportation fuels and natural gas distribution.

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 effect on our business.

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 the 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 effect 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. We could also be required to install expensive pollution control measures or limit or cease 
activities, including the retirement of certain generating plants, based on these regulations. Should we fail to comply with any 
environmental requirements that apply to power plant 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 the FERC makes the determination that we have market power, the 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 affect 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 effect on our financial condition, results of operations and cash flows.

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 at the beginning of this Report for a description of important factors that could cause actual results to

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 (included in our West segment), Texas (included in our Texas segment) and the Northeast and Mid-
Atlantic regions (included in our East segment) of the U.S. We sell 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 and other governmental entities, power marketers as well as retail commercial, industrial 
governmental and residential customers. We continue to focus on getting closer to our customers through expansion of our retail 
platform which began with the acquisition of Champion Energy in 2015 and was followed by the acquisitions of Calpine Solutions 
in late 2016 and North American Power in early 2017. We have invested in clean power generation to become a recognized leader 
in developing, constructing, owning and operating an environmentally responsible portfolio of flexible and reliable power plants. 

In  order  to  manage  our  various  physical  assets  and  contractual  obligations,  we  execute  commodity  and  commodity 
transportation agreements within the guidelines of our Risk Management Policy. We purchase primarily natural gas and some fuel 
oil as fuel for our power plants and engage in related natural gas transportation and storage transactions. We also purchase power 
for sale to our customers and purchase electric transmission rights to deliver power to our customers. Additionally, consistent with 
our Risk Management Policy, we enter into natural gas, power, environmental product, fuel oil and other physical and financial 
commodity contracts to hedge certain business risks and optimize our portfolio of power plants. Seasonality and weather can have 
a significant effect on our results of operations and are also considered in our hedging and optimization activities.

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

Subsequent to the completion of the sale of Osprey Energy Center on January 3, 2017 and the retirement of the Clear 
Lake Power Plant on February 1, 2017, our portfolio, including partnership interests, consists of 80 power plants, including one 
under construction, with an aggregate current generation capacity of 25,908 MW and 828 MW under construction. Our fleet, 
including projects under construction, consists of 65 natural gas-fired combustion turbine-based plants, one fuel oil-fired steam-
based plant, 13 geothermal steam turbine-based plants and one photovoltaic solar plant. Our segments have an aggregate generation 
capacity of 7,425 MW in the West, 9,027 MW in Texas and 9,456 MW with an additional 828 MW under construction in the East. 
Inclusive of our power generation portfolio and our retail sales platforms, we serve customers in 25 states in the U.S. and in Canada 
and Mexico.

In addition to the unique profile of our fleet, we believe our business is also advantaged by our capital allocation philosophy 
which seeks to maximize levered cash returns to equity while maintaining a strong balance sheet. We seek to enhance shareholder 
value through a diverse and balanced capital allocation approach that includes portfolio management, organic or acquisitive growth, 
returning capital to shareholders and debt reduction. The mix of this activity shifts over time given the external market environment 
and the opportunity set. In the current environment, we believe that paying down debt and strengthening our balance sheet is a 
high return investment for our shareholders. We also consider the repurchases of our own shares of common stock as an attractive 
investment opportunity, and we utilize the expected returns from this investment as the benchmark against which we evaluate all 
other capital allocation decisions. We believe this philosophy closely aligns our objectives with those of our shareholders.

Our  goal  is  to  be  recognized  as  the  premier  competitive  power  company  in  the  U.S.  as  viewed  by  our  employees, 
shareholders, customers and policy-makers as well as the communities in which our facilities are located. We seek to deliver long-
term shareholder value through operational excellence at our power plants and in our customer and commercial activity, as well 
as through our disciplined approach to capital allocation. A description of our strategy is included under Item 1. “Business — 
Strategy.”

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, decreased $288 million for the year ended December 31, 2016, compared 

to the year ended December 31, 2015, primarily due to:

(215) Lower energy margins due to decreased contribution from wholesale hedges, lower realized Spark Spreads in our 
Texas and West segments and the expiration of the Pastoria Energy Center PPA. These factors were partially offset 
by increased contribution from our retail hedging activity and the positive effect of a new PPA associated with 
our Morgan Energy Center in the East segment(1)

These items comprise the year-over-year change in our Commodity Margin which is a non-GAAP financial measure. See 
“Commodity Margin and Adjusted EBITDA” for a description of our Non-GAAP financial measures and a discussion of 
the year-over-year change in Commodity Margin by segment. 

(2)  Commodity Margin excludes amortization expense related to contracts recorded at fair value, non-cash GAAP-related 
adjustments to levelize revenues from tolling agreements, Commodity revenue and Commodity expense attributable to the 
noncontrolling interest and other unusual or non-recurring items.

Mark-to-market gain/loss from hedging our future generation, retail activities and fuel needs had a favorable variance of 

$112 million primarily driven by a decrease in net mark-to-market losses in the current year as compared to the prior year. 

Our normal, recurring plant operating expense decreased $38 million during 2016 compared to 2015. The decrease in 
our normal, recurring plant operating expense was primarily due to a $16 million decrease in repairs and maintenance expense 
and production-related expenses, a $7 million reduction in equipment failure costs related to outages, a $6 million decrease primarily 
from lower property taxes associated with two power plants in our Texas segment and a $9 million decrease in other miscellaneous 
expenses. The remaining net decrease of $3 million includes a $30 million decrease in major maintenance expense resulting from 
our plant outage schedule and costs from scrap parts related to outages, a $24 million decrease related to costs associated with a 
wildfire at our Geysers Assets in September 2015, a $40 million increase attributable to power plant portfolio changes and the 
acquisitions of our retail subsidiaries and an $11 million increase in stock based compensation expense and other miscellaneous 
items. 

In line with our strategy to focus on competitive wholesale markets and sell or contract power plants located in power 
markets dominated by regulated utilities or outside our strategic concentration, we completed the sale of the Mankato Power Plant 
in our East segment on October 26, 2016, resulting in a gain on sale of assets, net of $157 million during the year ended December 
31,  2016.  In  addition,  we  entered  into  an  asset  sale  agreement  on April  1,  2016  for  the  sale  of  substantially  all  of  the  assets 
comprising our South Point Energy Center to Nevada Power Company d/b/a NV Energy for approximately $76 million which 
resulted in an impairment loss of approximately $13 million that was recorded during the first quarter of 2016. See Note 3 of the 
Notes to Consolidated Financial Statements for further information regarding the sales of Mankato Power Plant and South Point 
Energy Center.

Debt modification and extinguishment costs for the year ended December 31, 2016, consisted of $15 million from the 
write-off of debt issuance costs in connection with the repayment of our 2019 and 2020 First Lien Term Loans in May 2016, $5 
million from the write-off of debt issuance costs in connection with repurchase of a portion of our 2023 First Lien Notes in 
December 2016 and $5 million in debt modification and extinguishment costs associated with the refinancing of project debt in 
51

 
 
 
November 2016. Debt modification and extinguishment costs for the year ended December 31, 2015, consisted of $26 million in 
debt extinguishment costs in connection with the repurchases of a portion of our 2023 First Lien Notes, which is comprised of 
$22 million of prepayment penalties and $4 million associated with the write-off of debt issuance costs and $13 million in debt 
modification costs related to the issuance of our 2024 First Lien Term Loan in May 2015. 

Other (income) expense, net increased by $10 million during 2016 compared to 2015 primarily due to a $5 million increase 
related to credit fees associated with our retail operations during 2016 and a $5 million increase resulting from a foreign currency 
translation loss related to our Canadian subsidiaries.

During the year ended December 31, 2016, we recorded income tax expense of $48 million compared to income tax 
benefit of $76 million for the year ended December 31, 2015. The unfavorable year-over-year change primarily resulted from an 
internal restructuring during 2015 of certain of our international entities by moving certain foreign subsidiaries under a different 
foreign parent. This restructuring resulted in our ability to further utilize foreign NOLs that were previously unavailable to offset 
the income tax obligation on future earnings and, thus, resulted in a partial release of our valuation allowance recorded against 
our NOLs. Additionally, the unfavorable year-over-year change resulted from recent acquisitions and domestic restructurings.

Mark-to-market gain/loss from hedging our future generation and fuel needs had an unfavorable variance of $455 million 

primarily driven by the maturity of favorable hedges during 2015 as compared to 2014.

Our normal, recurring plant operating expense decreased $3 million during 2015 compared to 2014 after excluding the 
net effect of a $8 million decrease from power plant portfolio changes, a $3 million decrease in stock based compensation expense, 
a $47 million increase in major maintenance expense resulting from our plant outage schedule and costs from scrap parts related 
to outages and a $16 million increase related to repairs to five of our geothermal power plants damaged by a wildfire in September 
of 2015. Repairs have been completed and our Geysers Assets are currently generating renewable power for our customers at pre-
fire levels.

Depreciation and amortization expense increased by $35 million during the year ended December 31, 2015, compared 
to the year ended December 31, 2014, primarily due to the acquisition of our Guadalupe and Fore River Energy Centers in February 
and  November  2014,  respectively,  the  acquisition  of  Champion  Energy  in  October  2015,  the  commencement  of  commercial 
operations at our Garrison Energy Center in June 2015 and the completion of our Deer Park and Channel Energy Center expansions 
in June 2014.

In line with our strategy to sell or contract power plants located in wholesale power markets dominated by regulated 
utilities and focus on competitive wholesale markets, we completed the sale of six of our power plants in our East segment on 
July 3, 2014, resulting in a gain on sale of assets, net of $753 million during the year ended December 31, 2014. In addition, we 
executed a term sheet with a third party related to our Osprey Energy Center in August 2014 for a new PPA with a term of 27 
months, after which the third party would purchase our Osprey Energy Center which resulted in an impairment loss of approximately 
$123 million that was recorded during the third quarter of 2014. See Notes 2 and 3 of the Notes to Consolidated Financial Statements 
for further information regarding the impairment and the sale of six power plants, respectively.

54

 
 
Interest expense decreased by $17 million for the year ended December 31, 2015, compared to the year ended December 
31, 2014, primarily due to a decrease in our annual effective interest rate on our consolidated debt, excluding the effect of capitalized 
interest and mark-to-market gains (losses) on interest rate hedging instruments, to 5.5% for the year ended December 31, 2015, 
from 5.9% for the year ended December 31, 2014. The issuance of our Senior Unsecured Notes in July 2014 and February 2015 
and our 2024 First Lien Term Loan in May 2015 allowed us to reduce our overall cost of debt by replacing a portion of our 2023 
First Lien Notes and all of our 2018 First Lien Term Loans with debt carrying lower interest rates.

Debt modification and extinguishment costs for the year ended December 31, 2015, consisted of $26 million in debt 
extinguishment costs in connection with the repurchases of a portion of our 2023 First Lien Notes, which is comprised of $22 
million  of  prepayment  penalties  and  $4  million  associated  with  the  write-off  of  debt  issuance  costs  and  $13  million  in  debt 
modification costs related to the issuance of our 2024 First Lien Term Loan in May 2015. Debt extinguishment costs for the year 
ended December 31, 2014, consisted primarily of $340 million related to the prepayment of our 2019 First Lien Notes, 2020 First 
Lien Notes and 2021 First Lien Notes, which is comprised of $306 million of prepayment penalties and $34 million associated 
with the write-off of unamortized debt discount and debt issuance costs.

During the year ended December 31, 2015, we recorded income tax benefit of $76 million compared to income tax 
expense of $22 million for the year ended December 31, 2014. The favorable year-over-year change primarily resulted from an 
internal restructuring of certain of our international entities by moving certain foreign subsidiaries under a different foreign parent 
during 2015. This restructuring resulted in our ability to further utilize foreign NOLs that were previously unavailable to offset 
the income tax obligation on future earnings and, thus, resulted in a partial release of our valuation allowance recorded against 
our NOLs. We do not currently believe that similar restructuring opportunities exist within our current tax structure. See Note 10 
of the Notes to Consolidated Financial Statements for further discussion of our NOLs and valuation allowance. In addition, a 
portion of the favorable year-over-year change relates to the recognition of a future tax benefit related to a tax credit associated 
with our capital expenditures.

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, environmental compliance expense, and realized settlements from our marketing, hedging, optimization 
and trading activities, but excludes 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 from operations by segment.

Commodity Margin by Segment for the Years Ended December 31, 2016 and 2015 

The following tables show our Commodity Margin and related operating performance metrics by segment for the years 
ended December 31, 2016 and 2015 (exclusive of the noncontrolling interest). In the comparative tables below, favorable variances

West — Commodity Margin in our West segment decreased by $115 million, or 10%, for the year ended December 31, 
2016 compared to the year ended December 31, 2015, primarily due to lower contribution from hedges, as we realized lower 
power prices at our Geysers Assets resulting from lower forward natural gas prices. Also contributing to the year-over-year decrease 
in Commodity Margin was the expiration of a PPA and a resource adequacy contract at our Pastoria Energy Center in December 
2015 and the expiration of the operating lease related to the Greenleaf power plants in June 2015. The decrease in Commodity 
Margin was partially offset by the receipt of a natural gas pipeline transportation billing credit during the second quarter of 2016. 
Generation decreased 25% primarily due to the suspension of operations at our Sutter Energy Center in 2016, the reclassification 
of our South Point Energy Center to inactive reserve in 2016 pending its sale in early 2017 and an increase in hydroelectric 
generation in California and the Pacific Northwest during the year ended December 31, 2016 compared to the same period in 
2015.

Texas — Commodity Margin in our Texas segment decreased by $81 million, or 11%, for the year ended December 31, 
2016 compared to the year ended December 31, 2015, primarily due to lower realized Spark Spreads resulting from a decrease in 
hedge value and lower market liquidations, partially offset by positive contribution from our retail hedging activity following the 
acquisitions of Champion Energy and Calpine Solutions in October 2015 and December 2016, respectively.

East — Commodity Margin in our East segment increased by $14 million for the year ended December 31, 2016 compared 
to  the  year  ended  December  31,  2015,  primarily  due  to  the  net  year-over-year  effect  of  our  portfolio  management  activities, 
including the acquisition of our 695 MW Granite Ridge Energy Center on February 5, 2016, the commencement of commercial 
operations at our 309 MW Garrison Energy Center in June 2015, partially offset by the sale of our 375 MW Mankato Power Plant 
in October 2016. Also contributing to the year-over-year increase in Commodity Margin was the positive effect of a new PPA 
associated with our Morgan Energy Center, which became effective in February 2016, and higher contribution from our retail 
hedging activity during 2016 following the acquisitions of Champion Energy and Calpine Solutions in October 2015 and December 
2016, respectively. The increase in Commodity Margin was partially offset by lower contribution from hedges in 2016 compared 
to 2015 and lower regulatory capacity revenue in PJM. Generation increased 17% primarily due to the acquisition of our 695 MW 
Granite Ridge Energy Center and the commencement of commercial operation at our 309 MW Garrison Energy Center.

West — Commodity Margin in our West segment increased by $56 million, or 5%, for the year ended December 31, 2015 
compared to the year ended December 31, 2014, primarily due to higher contribution from hedges, a 2% increase in generation 
from our power plants resulting from a decrease in hydroelectric generation in the Pacific Northwest and higher contractual REC 
revenues associated with our Geysers Assets resulting from more favorable REC pricing in 2015. The increase in Commodity 
Margin was partially offset by lower power prices and on-peak Spark Spreads resulting from lower natural gas prices, a wildfire 
in northern California in September 2015 which negatively affected our Geysers Assets and the expiration of the operating lease 
related to the Greenleaf power plants in June 2015.

Texas — Commodity Margin in our Texas segment decreased by $24 million, or 3%, for the year ended December 31, 
2015 compared to the year ended December 31, 2014, primarily due to lower contribution from summer hedges partially offset 
by the positive effect from hedging through our Champion Energy retail subsidiary beginning in the fourth quarter of 2015. Also 
contributing to the year-over-year decrease in Commodity Margin was lower on-peak Spark Spreads despite higher Market Heat 
Rates resulting from lower natural gas prices. The decrease in Commodity Margin was partially offset by a 24% increase in 
generation from our power plants resulting from higher off-peak Spark Spreads and lower natural gas prices that drove lower 
system-wide coal-fired generation from our competitors and a full year of operation in 2015 of our 1,000 MW Guadalupe Energy 
Center (which was acquired in February 2014) and our Deer Park and Channel Energy Center expansions (which were completed 
in June 2014).

East — Commodity Margin in our East segment increased by $76 million for the year ended December 31, 2015 compared 
to the year ended December 31, 2014, after excluding a decrease of $81 million resulting from the sale of six power plants with 
a total capacity of 3,498 MW on July 3, 2014, primarily due to higher contribution from hedges, a full year of operation in 2015 
of our 731 MW Fore River Energy Center which was acquired in November 2014 and the commencement of commercial operations 
at our 309 MW Garrison Energy Center in June 2015. Also contributing to the year-over-year increase in Commodity Margin was 
a 6% increase in generation resulting from lower natural gas prices that drove lower system-wide coal-fired generation from our 
competitors and the positive effect of a new contract for our Osprey Energy Center which became effective in the fourth quarter 
of 2014. The increase in Commodity Margin was partially offset by a significant decrease in power and natural gas prices in the 
first quarter of 2015 compared to the prior year period, given the unusually high price levels experienced during the polar vortex 
events in the first quarter of 2014 and lower regulatory capacity revenue in PJM during the first five months of 2015, partially 
offset by higher regulatory capacity revenue in PJM during the remaining seven months of 2015.

Adjusted EBITDA

We define Adjusted EBITDA, a non-GAAP financial measure, 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. 

58

GAAP. 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 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 mark-to-market gains or losses from accounting for derivatives, adjustments to exclude the Adjusted EBITDA related to the 
noncontrolling  interest,  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, modification or extinguishment of debt, non-
cash  GAAP-related  adjustments  to  levelize  revenues  from  tolling  agreements  and  any  unusual  or  non-recurring  items  plus 
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.

LIQUIDITY AND CAPITAL RESOURCES

We maintain a strong focus on liquidity. We manage our liquidity to help provide access to sufficient funding to meet 

our business needs and financial obligations throughout business cycles.

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

The following table provides a summary of our liquidity position at December 31, 2016 and 2015 (in millions):

(1) 

Includes $16 million and $35 million of margin deposits posted with us by our counterparties at December 31, 2016 and 
2015, respectively. See Note 9 of the Notes to Consolidated Financial Statements for further information related to our 
collateral. On January 3, 2017, we received $162 million in cash proceeds from the sale of Osprey Energy Center. See Note 
3 of the Notes to Consolidated Financial Statements for further information related to our sale of Osprey Energy Center.

(2)  Our ability to use availability under our Corporate Revolving Facility is unrestricted. On February 8, 2016, we amended 
our Corporate Revolving Facility, extending the maturity by two years to June 27, 2020, and increasing the capacity by an 
additional $178 million to $1,678 million through June 27, 2018, reverting back to $1,520 million through the maturity 
date. Further, we increased the letter of credit sublimit by $250 million to $1.0 billion and extended the maturity by two 
years to June 27, 2020. On December 1, 2016, we amended our Corporate Revolving Facility, increasing the capacity by 
$112 million to $1,790 million for the full term through June 27, 2020.

(3)  Our ability to use corporate cash and cash equivalents is unrestricted. See Note 2 of the Notes to Consolidated Financial 
Statements for a description of the restrictions on our use of non-corporate cash and cash equivalents and restricted cash. 
Our $300 million CDHI letter of credit facility is restricted to support certain obligations under PPAs and power transmission 
and natural gas transportation agreements.

Our principal source for future liquidity is cash flows generated from our operations. 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. See “Cash Flow Activities” below for a further discussion of our change in cash and cash equivalents.

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,  capital  expenditures  for  construction,  project  development  and  other  growth  initiatives  and 
opportunistically  repaying  debt  to  manage  our  balance  sheet.  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. 

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 funds that are not 
FDIC insured. We place our cash, cash equivalents and restricted cash in what we believe to be creditworthy financial institutions.

We have never paid cash dividends on our common stock. Future cash dividends, if any, may be authorized at the discretion 
of our Board of Directors and will depend upon, among other things, our future operations and earnings, capital requirements, 

63

general financial condition, contractual and financing restrictions and such other factors as our Board of Directors may deem 
relevant.

Liquidity Sensitivity

Significant changes in commodity prices and Market Heat Rates can affect 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 December 31, 
2016, an increase of $1/MMBtu in natural gas prices would result in a decrease of collateral required by approximately $89 million. 
If natural gas prices decreased by $1/MMBtu, we estimate that our collateral requirements would increase by approximately $242 
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 December 31, 2016, an 
increase of 500 Btu/KWh in the Market Heat Rate would result in an increase in collateral required by approximately $25 million. 
If Market Heat Rates were to fall at a similar rate, we estimate that our collateral required would increase by $7 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, we have economically hedged a portion of our expected 
generation and natural gas portfolio as well as retail load supply obligations, where appropriate, mostly through power and natural 
gas forward physical and financial transactions including retail power sales; however, we currently remain susceptible to significant 
price movements for 2017 and beyond. In addition to the price of natural gas, 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;

changes in U.S. macroeconomic conditions;

•  maintaining acceptable availability levels for our fleet;

• 

• 

• 

• 

the effect 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.

Wildfire at our Geysers Assets

In September 2015, a wildfire spread to our Geysers Assets in Lake and Sonoma counties, California. The wildfire affected 
several of our geothermal power plants in the region, which sustained damage to ancillary structures such as cooling towers and 
communication/electric deliverability infrastructure. Repairs have been completed and our Geysers Assets are currently generating 
renewable power for our customers at pre-fire levels. The repair and replacement costs, as well as our net revenue losses relating 
to the wildfire, were limited to our insurance deductibles of approximately $36 million, all of which was recognized in 2015. The 
losses incurred in 2016 related to the wildfire were primarily offset by insurance proceeds. We record insurance proceeds in the 
same financial statement line as the related loss is incurred and recorded approximately $24 million and $2 million in business 
interruption proceeds in operating revenues during the years ended December 31, 2016 and 2015, respectively. The wildfire and 
insurance proceeds recovery did not have a material effect on our financial condition, results of operations or cash flows.

Operating Event at our Delta Energy Center

On  January  29,  2017,  we  experienced  an  operating  event  at  our  Delta  Energy  Center  that  resulted  in  an  emergency 
shutdown of the power plant, the duration of which has yet to be determined. We are currently assessing the damage to the plant, 
in particular the steam turbine and steam turbine generator. Based on preliminary information, we anticipate that insurance will 
cover a significant portion of our losses, after applicable deductibles.

NOLs

We have significant NOLs that will provide future tax deductions when we generate sufficient taxable income during the 
applicable carryover periods. At December 31, 2016, our consolidated federal NOLs totaled approximately $6.7 billion. See Note 
10 of the Notes to Consolidated Financial Statements for further discussion of our NOLs.

2016 — 2015

Net Cash Provided By Operating Activities 

Cash provided by operating activities for the year ended December 31, 2016, was $1,030 million compared to $876 

million for the year ended December 31, 2015. The increase was primarily due to:

• 

Income from operations — Income from operations, adjusted for non-cash items, decreased by $136 million for the 
year ended December 31, 2016, compared to the same period in 2015. Non-cash items consist primarily of depreciation 
and amortization, income from unconsolidated subsidiaries, gain on sale of assets and mark-to-market activity. The 

65

 
 
decrease in income from operations was primarily driven by a $186 million decrease in Commodity revenue, net of 
Commodity expense, excluding non-cash amortization, partially offset by a $41 million decrease in plant operating 
expense. See “Results of Operations for the Year Ended December 31, 2016 and 2015” above for further discussion 
of these changes.

•  Working capital employed — Working capital employed decreased by $202 million for the year ended December 
31, 2016, compared to the same period in 2015, after adjusting for changes in debt, restricted cash and mark-to-
market related balances which did not affect cash provided by operating activities. The decrease was primarily due 
to the recovery of cash margin posted by Calpine Solutions through position netting and letter of credit conversion 
opportunities.  

• 

Interest paid — Cash paid for interest decreased by $36 million to $584 million for the year ended December 31, 
2016, from $620 million for the year ended December 31, 2015.  The decrease was primarily due to our refinancing 
activities and timing of interest payments.

•  Debt modification & extinguishment payments — During the year ended December 31, 2016, we made cash payments 
of $5 million related to the repurchase penalties for a portion of the 2023 First Lien Notes and the refinancing and 
upsizing of Steamboat project debt as compared to $34 million during the year ended December 31, 2015, associated 
with the repurchase penalties for a portion of the 2023 First Lien Notes and debt modification costs related to the 
issuance of the 2024 First Lien Term Loan.  

Net Cash Used In Investing Activities 

Cash used in investing activities for the year ended December 31, 2016, was $1,919 million compared to $841 million 

for the year ended December 31, 2015. The increase was primarily due to:

•  Purchase of Calpine Solutions and Champion Energy — During the year ended December 31, 2016, we purchased 
the retail electric provider Calpine Solutions, formerly Noble Solutions, for $1.15 billion compared to the purchase 
of Champion Energy for $296 million during the year ended December 31, 2015.

•  Purchase of Granite Ridge Energy Center — During the year ended December 31, 2016, we purchased a natural 
gas-fired combined-cycle power plant located in Londonderry, New Hampshire for $526 million. There were no 
similar acquisitions during the year ended December 31, 2015.

•  Proceeds from the sale of Mankato Power Plant — During the year ended December 31, 2016, we received net 
proceeds after the pay-down of Steamboat project debt of approximately $164 million for the sale of Mankato Power 
Plant. There were no power plants sold during the year ended December 31, 2015.

•  Capital expenditures — Capital expenditures for the year ended December 31, 2016, were $489 million, a decrease 
of $76 million, compared to expenditures of $565 million for the year ended December 31, 2015. The decrease was 
primarily due to lower expenditures on construction projects and outages.

Net Cash Provided By Financing Activities 

Cash provided by financing activities for the year ended December 31, 2016, was $401 million compared to $154 million 

for the year ended December 31, 2015. The increase was primarily due to:

•  First Lien Term Loans, First Lien Notes and Senior Unsecured Notes — During the year ended December 31, 2016, 
we received proceeds of $545 million from the issuance of the 2017 First Lien Term Loan used to partially fund the 
purchase of Calpine Solutions and redeemed $120 million of the 2023 First Lien Notes. In addition, we utilized 
proceeds from the issuance of the New 2023 First Lien Term Loan and the 2026 First Lien Notes to repay the 2019 
and 2020 First Lien Term Loans of $1.2 billion. During the year ended December 31, 2015, we received proceeds 
of $650 million from the issuance of the 2024 Senior Unsecured Notes, proceeds of $545 million from the issuance 
of 2023 First Lien Term Loan used to fund the purchase of Granite Ridge Energy Center and repurchased $267 
million of the 2023 First Lien Notes. In addition, we utilized proceeds from the issuance of the 2024 First Lien Term 
Loan to repay the 2018 First Lien Term Loan of $1.6 billion.

• 

Stock repurchases — During the year ended December 31, 2016, we repurchased an immaterial amount of common 
stock as compared to $529 million paid to repurchase our common stock during the year ended December 31, 2015.

•  Project financing, notes payable and other — During the year ended December 31, 2016, we refinanced and upsized 
Steamboat project debt following the sale of Mankato Power Plant. The refinancing resulted in net proceeds received 

66

of $20 million after the noncash pay-down of the debt in the amount of $243 million in conjunction with the sale of 
Mankato and proceeds received from the upsizing and refinancing in the amount of $263 million. There were no 
similar activities during the year ended December 31, 2015.

2015 — 2014

Net Cash Provided By Operating Activities 

Cash provided by operating activities for the year ended December 31, 2015, was $876 million compared to $870 million 

for the year ended December 31, 2014. The increase was primarily due to:

• 

Income from operations — Income from operations, adjusted for non-cash items, increased by $59 million for the 
year ended December 31, 2015, compared to the year ended December 31, 2014. Non-cash items consist primarily 
of depreciation and amortization, income from unconsolidated subsidiaries, impairment losses, gain on sale of assets, 
net and mark-to-market activity. The increase in income from operations was primarily driven by a $94 million 
increase in Commodity revenue, net of Commodity expense, excluding non-cash amortization of purchased intangible 
assets, partially offset by a $49 million increase in plant operating expense for the year ended December 31, 2015 
compared to the year ended December 31, 2014. See “Results of Operations for the Years Ended December 31, 2015 
and 2014” above for further discussion of these changes.

•  Working capital employed — Working capital employed increased by $331 million for the year ended December 31, 
2015, compared to the year ended December 31, 2014, after adjusting for changes in debt, restricted cash and mark-
to-market related balances which did not affect cash provided by operating activities. The increase was primarily 
due to the change in net margining requirements for the year ended December 31, 2015, compared to the year ended 
December 31, 2014.

•  Debt modification and extinguishment payments — Cash paid for debt modification and extinguishment decreased 
$276 million to $34 million during the year ended December 31, 2015, from $310 million for the year ended December 
31, 2014. During the year ended December 31, 2015, we made cash payments of $13 million related to issuance 
costs associated with our 2024 First Lien Term Loan and cash payments of $21 million related to the repayment of 
a portion of our 2023 First Lien Notes, as compared to $310 million during the year ended December 31, 2014, 
which was associated with the repayment of our 2019 First Lien Notes, 2020 First Lien Notes and 2021 First Lien 
Notes and a portion of our 2023 First Lien Notes.

Net Cash Used In Investing Activities 

Cash used in investing activities for the year ended December 31, 2015, was $841 million compared to $84 million for 

the year ended December 31, 2014. The increase was primarily due to:

•  Proceeds from the sale of power plants and other — During the year ended December 31, 2014, we received proceeds 
of approximately $1.57 billion related to the completion of the sale of six power plants in our East segment.  There 
was no similar activity during the year ended December 31, 2015.

•  Purchase of Champion Energy, Fore River and Guadalupe Energy Centers — During the year ended December 31, 
2015, we purchased the retail electric provider Champion Energy for $296 million compared to the purchase of two 
natural gas-fired, combined-cycle power plants located in North Weymouth, Massachusetts and Guadalupe County, 
Texas for $541 million and $656 million, respectively, during the year ended December 31, 2014.

•  Capital expenditures — Capital expenditures for the year ended December 31, 2015, were $565 million, an increase 
of $73 million, compared to expenditures of $492 million for the year ended December 31, 2014. The increase was 
primarily due to higher expenditures on construction projects and outages during the year ended December 31, 2015, 
as compared to the year ended December 31, 2014.

Net Cash Provided By (Used In) Financing Activities 

Cash provided by financing activities for the year ended December 31, 2015, was $154 million compared to cash used 

in financing activities of $1,010 million for the year ended December 31, 2014. The increase was primarily due to:

•  First Lien Term Loans — During the year ended December 31, 2015, we received proceeds of approximately $1.6 
billion from the issuance of the 2024 First Lien Term Loan which was used to repay the 2018 First Lien Term Loan 
of $1.6 billion. In addition, we received proceeds of approximately $545 million from the issuance of the 2023 First 
Lien Term Loan which is intended to be used, together with operating cash on hand, to fund the acquisition of Granite 
Ridge Energy Center, to repay project and corporate debt and for general corporate purposes. There was no similar 
activity during the year ended December 31, 2014. 

67

 
•  CCFC refinancing — During the year ended December 31, 2014, we received proceeds of $420 million under the 
CCFC Term Loans, which were used to fund a portion of the purchase price paid in connection with the acquisition 
of the Guadalupe Energy Center. There was no similar activity during the year ended December 31, 2015.

•  First Lien Notes and Senior Unsecured Notes — During the year ended December 31, 2015, we received proceeds 
of $650 million from the issuance of the 2024 Senior Unsecured Notes which were used to replenish cash on hand 
used for the acquisition of Fore River Energy Center in the fourth quarter of 2014, to repurchase $147 million of our 
2023 First Lien Notes and for general corporate purposes. In addition, we redeemed $120 million of our 2023 First 
Lien Notes. During the year ended December 31, 2014, we received proceeds of $2.8 billion from the issuance of 
Senior Unsecured Notes, which were used to repurchase our 2019 First Lien Notes, 2020 First Lien Notes and 2021 
First Lien Notes of $2.8 billion and we repurchased $120 million of our 2023 First Lien Notes.

• 

Stock repurchases — During the year ended December 31, 2015, we made payments of $529 million to repurchase 
our common stock compared to $1.1 billion during the year ended December 31, 2014. The decrease is primarily 
due to the repurchase of $311 million of common stock from a shareholder in a private transaction during the year 
ended December 31, 2014.

Counterparties and Customers

Our counterparties and customers primarily consist of four categories of entities who participate in the energy markets: 
financial institutions and trading companies; regulated utilities, municipalities, cooperatives, ISOs and other retail power suppliers; 
oil, natural gas, chemical and other energy-related industrial companies; and commercial, industrial and residential retail customers. 
We  have  exposure  to  trends  within  the  energy  industry,  including  declines  in  the  creditworthiness  of  our  counterparties  and 
customers. We have concentrations of credit risk with a few of our wholesale counterparties relating to our sales of power and 
steam and our hedging, optimization and trading activities. Currently, certain of our counterparties and customers 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. Currently, our wholesale counterparties and retail customers are performing and financially 
settling timely according to their respective agreements with the exception of certain retail customers where our credit exposure 
is not material.

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 reduces the number of hedging 
counterparties willing to extend credit to us and reduces 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, 2016, our First Lien Notes, First Lien Term Loans, Corporate Revolving Facility, 
Senior Unsecured Notes 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 lease is not reflected on our Consolidated Balance Sheets and contains 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 lease.

Some of our unconsolidated equity method investments have debt that is not reflected on our Consolidated Balance 
Sheets. As of December 31, 2016, our investments in Greenfield LP and Whitby had aggregate debt outstanding of $259 million. 
Based on our pro rata share of each of the investments, our share of such debt would be approximately $130 million. All such debt 
is non-recourse to us.

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, retail contracts, contracts associated with the development, construction, operation 
and maintenance of our fleet of power plants and our Accounts Receivable Sales Program. See Note 15 of the Notes to Consolidated

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. A description of risk management activities 
is included under Item 1. “Business — Marketing, Hedging and Optimization Activities.” 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 hedging instruments. 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  increased  to  approximately  $2.3  billion  at  December 31,  2016,  when  compared  to 
approximately $2.0 billion at December 31, 2015, and our derivative liabilities have decreased to approximately $2.1 billion at 
December 31, 2016, when compared to approximately $2.2 billion at December 31, 2015. The fair value of our level 3 derivative 
assets and liabilities at December 31, 2016 represents approximately 14% and 3% of our total assets and liabilities measured at 
fair value, respectively, with the majority of that value attributable to the fair value of retail sales contracts acquired in the acquisition 
of Calpine Solutions, formerly Noble Solutions, in December 2016. 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 hedging instruments from January 1, 2016, 

through December 31, 2016, is summarized in the table below (in millions):

__________

(1)  Commodity contract settlements consist of the realization of previously recognized gains on contracts not designated as 
hedging instruments of $102 million (represents a portion of Commodity revenue and Commodity expense as reported on 
our Consolidated Statements of Operations) and $89 million related to current period gains from other changes in derivative 
assets and liabilities not reflected in OCI or earnings.

(2) 

Interest rate settlements consist of $33 million related to realized losses from settlements of designated cash flow hedges 
and $5 million related to realized losses from settlements of undesignated interest rate hedging instruments (represents a 
portion of interest expense as reported on our Consolidated Statements of Operations) and $8 million of losses on interest 
rate hedging instruments that were terminated as a result of the repayment and refinancing of debt in fourth quarter of 2016.

(3)  Consist of $238 million in gains related to hedges acquired from the acquisition of Calpine Solutions, formerly Noble 

Solutions.

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

Financial Statements.

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.

We measure the energy commodity price risk 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 potential market movements. Our VAR is calculated for our 
entire portfolio comprising energy commodity derivatives, expected generation and natural gas consumption from our power 
plants, PPAs, and other physical and financial transactions. 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, 2016 and 2015

(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 effect 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  analysis,  non-statistical  scenario  analysis,  including  stress  testing,  and  daily 
position report analysis.

We utilize the forward commodity markets to hedge price risk associated with our power plant portfolio. Our ability to 
hedge relies in part on market liquidity and the number of counterparties with which to transact. While the number of counterparties 
in these markets has decreased, to date this occurrence has not had a material adverse effect on our results of operations or financial 
condition. However, should these conditions persist or increase, it could decrease our ability to hedge our forward commodity 
price risk and create incremental volatility in our earnings. The effects of declining liquidity in the forward commodity markets 
is also mitigated by our retail subsidiaries which provides us with an additional outlet to transact hedging activities related to our 
wholesale power plant portfolio.

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 
or customers related to their contractual obligations with us. Risks surrounding counterparty and customer performance and credit 
could ultimately affect the amount and timing of expected cash flows. We also have credit risk if counterparties or customers 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’ and customer’s credit limits and their overall credit ratings;

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

•  margin, collateral, or prepayment arrangements; and

71

 
• 

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 wholesale counterparties and retail customers relating to our sales 
of power and steam and our hedging, optimization and trading activities. We believe that our credit policies and portfolio of 
transactions adequately monitor and diversify our credit risk, and currently our counterparties and customers 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 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  and  customer  credit  quality  associated  with  the  net  fair  value  of  outstanding  derivative  commodity 
instruments is included in our derivative assets and (liabilities) at December 31, 2016, 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, 2016. All outstanding balances and fair market values are shown gross of applicable

Projection based upon forward LIBOR rates inferred from spot rates at December 31, 2016.

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  hedging  instruments  are 
validated based upon external quotes. Our interest rate hedging instruments are with counterparties we believe are primarily high 
quality institutions, and we do not believe that our interest rate hedging instruments 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 hedging instruments hedging our variable rate debt of approximately $(15) million at December 31, 2016.

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.

72

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 
affect 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 (capacity payments) 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 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 and ISO-NE 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, unless qualified as a lease, 
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 
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. 

73

 
 
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 and customers for energy commodity derivatives; and prevailing interest 
rates for our interest rate hedging instruments. 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 or Intercontinental Exchange 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 hedging instruments and OTC power and natural gas 
forwards for which market-based pricing inputs in the principal or most advantageous market are representative of executable 
prices for market participants are classified as level 2 fair value measurements. These inputs are observable at commonly quoted 
intervals for substantially the full term of the instruments.

Our OTC power and natural gas forwards and options where pricing inputs are unobservable, as well as other complex 
and structured transactions primarily for the sale of power to both wholesale counterparties and retail customers are classified as 
level 3 fair value measurements. Complex or structured transactions are tailored to 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 effect 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 customers and the effect of credit enhancements, if any. We assess non-performance risk by adjusting 
the fair value of our derivatives based on our credit standing or the credit standing of our counterparties and customers involved 
and the effect 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 or customer. 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.

74

Impairments

When we determine that 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 effect 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 effect of such variations could be material.

Acquisitions of Assets and Liabilities

U.S. GAAP requires that the purchase price for an acquisition, such as the acquisitions of Granite Ridge Energy Center 
and Calpine Solutions, formerly Noble Solutions, 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 can result in the recognition of goodwill. 
In addition to the potential for the recognition of goodwill, differing fair values will affect the allocations of the purchase price to 
the individual assets and liabilities and can affect the gross amount and classification of assets and liabilities recorded on our 
Consolidated Balance Sheet and can affect 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. Revenues and expenses 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. 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 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 
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 only apply hedge accounting to our interest rate hedging instruments. We report the effective 
portion of the mark-to-market gain or loss on our interest rate hedging instruments 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 interest rate hedging instruments are recognized 
currently in earnings as a component of interest expense. 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 affects 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, interest rate, environmental 
product and fuel oil transactions that primarily act as economic hedges to our asset and interest rate portfolio, but either do not 

75

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 mark-to-market gain/
loss as a component of operating revenues (for physical and financial power and Heat Rate and commodity option activity) and 
fuel and purchased energy expense (for physical and financial natural gas, power, environmental product and fuel oil activity). 
Changes in fair value of interest rate derivatives not designated as hedging instruments are recognized currently in earnings as 
interest expense.

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

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 affect 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  effect  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 affect 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 affect 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 in unconsolidated 
subsidiaries on our Consolidated Balance Sheets. Our equity interest in the net income from Greenfield LP and Whitby for the 
years ended December 31, 2016, 2015 and 2014, are recorded in (income) from unconsolidated subsidiaries.

76

We have a 100% membership interest in Calpine Receivables, a bankruptcy remote entity created for the special purpose 
of purchasing trade accounts receivable from Calpine Solutions under the Accounts Receivable Sales Program. Calpine Receivables 
is a VIE as we have determined that we do not have the power to direct the activities of the VIE that most significantly affect the 
VIE’s economic performance nor the obligation to absorb losses or receive benefits from the VIE. Accordingly, we have determined 
that we are not the primary beneficiary of Calpine Receivables as we do not have the  power to affect its financial performance 
as the unaffiliated financial institutions that purchase the receivables from Calpine Receivables control the selection criteria of 
the receivables sold and appoint the servicer of the receivables which controls management of default. Thus, we do not consolidate 
Calpine Receivables in our Consolidated Financial Statements and we use the equity method of accounting to record our net 
interest in Calpine Receivables.

We hold a call option to purchase the Inland Empire Energy Center (a 775 MW natural gas-fired power plant located in 
California) 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 
change in the amounts and timing of when we recognize depreciation expense and therefore significantly affect our financial 
condition and results of operations from period to period. Different depreciation methods can affect 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 affect 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 is reduced by the assets’ estimated salvage values. 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 
where we own the power plant or have a favorable option to purchase the power plant or take ownership of the power plant 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 Goodwill, 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 property, plant and 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. We use a fundamental long-term view of the power market which is based on 

77

long-term production volumes, price curves and operating costs together with the regulatory and environmental requirements 
within each individual market to prepare our multi-year forecast. Since we manage and market our power sales as a portfolio rather 
than at the individual power plant level or customer level within each designated market, pool or segment, we group our power 
plants based upon the corresponding market for valuation purposes. If we determine that the undiscounted cash flows from an 
asset or group of assets to be held and used are less than the associated carrying amount, or if we have classified an asset as held 
for sale, we must estimate fair value to determine the amount of any impairment loss. 

We have temporarily suspended operations at our Sutter Energy Center. While the long-term market forecasted cash 
flows continue to support the carrying value of the asset, if the forecasted cash flows were to materially deteriorate, this could 
result in a permanent shut down of the facility and in the recognition of an impairment of our Sutter Energy Center and other 
plants within the respective market.

When we believe an impairment condition may exist on specifically identifiable finite-lived 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.” 

We test goodwill and all intangible assets not subject to amortization for impairments at least annually, or more frequently 
whenever an event or change in circumstances occurs that would more likely than not reduce the fair value of a reporting unit 
below its carrying amount. We test goodwill for impairment at the reporting unit level, which is identified one level below the 
Company’s  operating  segments  for  which  discrete  financial  information  is  available  and  management  regularly  reviews  the 
operating results. We perform an annual impairment assessment in the third quarter of each year, or more frequently if indicators 
of potential impairment exist, to determine whether it is more likely than not that the fair value of a reporting unit in which goodwill 
resides is less than its carrying value. For reporting units in which this assessment concludes that it is more likely than not that 
the fair value is more than its carrying value, goodwill is not considered impaired and we are not required to perform the two-step 
goodwill impairment test. Qualitative factors considered in this assessment include industry and market considerations, overall 
financial performance, and other relevant events and factors affecting the reporting unit.

For reporting units in which the impairment assessment concludes that it is more likely than not that the fair value is less 
than its carrying value, we perform the first step of the goodwill impairment test, which compares the fair value of the reporting 
unit to its carrying value. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, 
goodwill is not considered impaired and we are not required to perform additional analysis. If the carrying value of the net assets 
assigned to the reporting unit exceeds the fair value of the reporting unit, then we must perform the second step of the goodwill 
impairment test to determine the implied fair value of the reporting unit’s goodwill. If we determine during the second step that 
the carrying value of a reporting unit’s goodwill exceeds its implied fair value, we record an impairment loss equal to the difference.

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 
effect on our income tax provision, other tax accounts and net income in the period in which such determination is made.

As of December 31, 2016, our NOL carryforwards consisted primarily of federal NOL carryforwards of approximately 
$6.7 billion, which expire between 2024 and 2033, and NOL carryforwards in 21 states and the District of Columbia totaling 
approximately  $3.7  billion,  which  expire  between  2017  and  2036,  substantially  all  of  which  are  offset  with  a  full  valuation 
allowance. We also have approximately $647 million in foreign NOLs, which expire between 2025 and 2033, of which a portion  
is offset with a 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.

78

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 effect on our financial condition or results of operations. As of December 31, 2016, we had $59 million of unrecognized 
tax benefits from uncertain tax positions.

See Note 10 of the Notes to Consolidated Financial Statements for further discussion of our accounting for income taxes.

Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in 
our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules 
and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer 
and Chief Financial Officer, as appropriate, to allow timely decisions regarding required financial disclosure.

As of the end of the period covered by this Report, we carried out an evaluation, under the supervision and with the 
participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the 
design and operation of our disclosure controls and procedures as defined in Rule 13a-15(e) or Rule 15d-15(e) of the Exchange 
Act. Based upon, and as of the date of, this evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that 
our disclosure controls and procedures were effective such that the information required to be disclosed in our SEC reports is 
recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and is accumulated and

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.

79

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, 2016. In 
making  its  assessment  of  internal  control  over  financial  reporting,  management  used  the  criteria  described  in  Internal 
Control — Integrated Framework (2013) 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, 2016 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.

In  accordance  with  guidance  issued  by  the  SEC,  companies  are  permitted  to  exclude  acquisitions  from  their  final 
assessment of internal control over financial reporting for the first fiscal year in which the acquisition occurred. On December 1, 
2016 and as further discussed in Note 3 of the Notes to Consolidated Financial Statements, we completed the acquisition of Calpine 
Solutions,  formerly  Noble  Solutions,  which  represented  approximately  7%  of  total  assets  and  2%  of  revenues  of  our  related 
consolidated financial statement amounts as of and for the year ended December 31, 2016. We have elected to exclude Calpine 
Solutions’ operations from our assessment of internal control over financial reporting as of December 31, 2016. 

The  effectiveness  of  our  internal  control  over  financial  reporting  as  of  December 31,  2016,  has  been  audited  by 

PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Changes in Internal Control Over Financial Reporting

During the fourth quarter of 2016, there were no changes in our internal control over financial reporting (as defined in 
Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that materially affected, or are reasonably likely to materially affect, our 
internal control over financial reporting.

Item 9B.  Other Information

Effective February 9, 2017, Trey Griggs, formerly our Executive Vice President and Chief Commercial Officer, will

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, 2016 and 2015, and the results of their 
operations and their cash flows for each of the three years in the period ended December 31, 2016 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, 2016, based on criteria established in Internal 
Control - Integrated Framework (2013) 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.

As described in Management's Report on Internal Control Over Financial Reporting, management has excluded Calpine Energy 
Solutions LLC from its assessment of internal control over financial reporting as of December 31, 2016 because it was acquired 
by the Company in a purchase business combination during 2016. We have also excluded Calpine Energy Solutions LLC from 
our audit of internal control over financial reporting. Calpine Energy Solutions LLC is a wholly-owned subsidiary whose total 
assets and total revenues represent 7% and 2%, respectively, of the related consolidated financial statement amounts as of and for 
the year ended December 31, 2016.

CALPINE CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
For the Years Ended December 31, 2016, 2015 and 2014

1. 

Organization and Operations

We are a 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 
(included in our West segment), Texas (included in our Texas segment) and the Northeast and Mid-Atlantic regions (included in 
our East segment) of the U.S. We sell 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  and  other  governmental  entities,  power  marketers  as  well  as  retail  commercial,  industrial,  governmental  and 
residential customers. We continue to focus on getting closer to our customers through expansion of our retail platform which 
began with the acquisition of Champion Energy in 2015 and was followed by the acquisitions of Calpine Solutions in late 2016 
and North American Power in early 2017. We purchase primarily natural gas and some fuel oil as fuel for our power plants and 
engage in related natural gas transportation and storage transactions. We also purchase power for sale to our customers and purchase 
electric transmission rights to deliver power to our customers. Additionally, consistent with our Risk Management Policy, we enter 
into natural gas, power, environmental product, fuel oil and other physical and financial commodity contracts to hedge certain 
business risks and optimize our portfolio of power plants.

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, Whitby, a 50%
partnership interest and Calpine Receivables, a 100% membership 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 or limited liability company 
operating agreement. See Note 5 for further discussion of our VIEs and unconsolidated investments.

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.

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 Note 7 for disclosures regarding the fair values of our derivative instruments and margin deposits and certain of our cash 
balances.

99

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 financial instruments. 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 and customers, 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 and customers, 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 and customers primarily consist of four categories of entities who participate in the energy markets:

• 

• 

• 

• 

financial institutions and trading companies;

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

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

commercial, industrial and residential retail customers.

We have concentrations of credit risk with a few of our wholesale counterparties and retail customers relating to our sales 
of power and steam and our hedging, optimization and trading activities. We have exposure to trends within the energy industry, 
including declines in the creditworthiness of our counterparties and customers for our commodity and derivative transactions. 
Currently, certain of our counterparties and customers within the energy industry have below investment grade credit ratings. Our 
risk control group manages counterparty and customer credit risk and monitors our net exposure with each counterparty or customer 
on a daily basis. The analysis is performed on a mark-to-market basis using forward curves. The net exposure is compared against 
a credit risk threshold which is determined based on each counterparties’ and customer’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 or customer. We believe that our credit policies and portfolio of transactions adequately monitor and diversify our 
credit risk. Currently, our wholesale counterparties and retail customers are performing and financially settling timely according 
to their respective agreements with the exception of certain retail customers where our credit exposure is not material. 

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 cash and cash equivalents held in non-corporate accounts relating to certain project finance facilities and lease agreements 
that require us to establish and maintain segregated cash accounts. These accounts 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.

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, making these cash funds unavailable for general use. 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 and major maintenance 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 Condensed Balance Sheets and Statements of Cash Flows.

 We record business interruption insurance proceeds when they are realizable and recorded approximately $24 million
and  $2  million  of  business  interruption  proceeds  in  operating  revenues  for  the  years  ended  December 31,  2016  and  2015, 
respectively. We did not record any business interruption proceeds during the year ended December 31, 2014.

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 reviewed for collectability, depending upon the nature of the customer, and if deemed uncollectible, are 
charged off against the allowance account 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. 

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.

Accounts Receivable Sales Program

On December 1, 2016, in conjunction with our acquisition of Calpine Solutions, we entered into the Accounts Receivable 
Sales Program which allows us to sell, at a discount, up to $250 million in certain trade accounts receivable, arising from the sale 
of  power  and  natural  gas,  from  Calpine  Solutions  to  Calpine  Receivables  which  in  turn  sells  100%  of  the  receivables  to  an 
unaffiliated  financial  institution,  subject  to  certain  contractual  limitations.  The Accounts  Receivable  Sales  Program,  which 
supersedes a similar program by the previous owner, expires on December 1, 2017. Calpine Solutions continues to service the 
receivables sold in exchange for a servicing fee which was not material for the year ended December 31, 2016. We are not the 
primary  beneficiary  of  Calpine  Receivables  and,  accordingly,  do  not  consolidate  this  entity  in  our  Consolidated  Financial 
Statements. See Note 5 for a further discussion of our unconsolidated VIEs. Any portion of the purchase price for the sold receivables 
which is not paid in cash is recorded as a note receivable. The note receivable is recorded at fair value and does not materially 
differ from the carrying value of the trade accounts receivable held prior to sale due to the short-term nature of the receivables 
and  high  credit  quality  of  the  retail  customers  involved.  Receivables  sold  under  the Accounts  Receivable  Sales  Program  are 
accounted for as sales and excluded from accounts receivable on our Consolidated Balance Sheets and reflected as cash provided 
by operating activities on our Consolidated Statements of Cash Flows. Calpine has guaranteed the performance of Calpine Solutions 
under the Accounts Receivable Sales Program. See Note 15 for a further description of our guarantees.

At December 31, 2016, we had $211 million in trade accounts receivable outstanding that were sold under the Accounts 
Receivable Sales Program and $32 million in notes receivable which was recorded on our Consolidated Balance Sheet. We sold 
an aggregate of approximately $165 million in trade accounts receivable during the year ended December 31, 2016 and recorded 
proceeds of approximately $165 million during the year ended December 31, 2016. Any losses incurred on the sale of trade accounts 
receivable are recorded in other (income) expense, net on our Consolidated Statements of Operations which were not material 
during the year ended December 31, 2016.

101

 
 
 
Inventory

Inventory primarily consists of spare parts, stored natural gas and fuel oil, environmental products 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 and customers 
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 hedging instruments 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.

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, certain replacements or repairs when the 
repairs 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 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 power plant or have a favorable option to purchase the power plant or take ownership of the power plant 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.

Goodwill and Intangible Assets

Goodwill represents the excess of the purchase price over the fair value of the net assets acquired at the time of an 
acquisition. We assess the carrying amount of our goodwill annually during the third quarter and whenever the events or changes 
in circumstances indicate that the carrying value may not be recoverable. As of December 31, 2016 and 2015, our goodwill was 
$187 million and $29 million, respectively and is reflected in other assets on our Consolidated Balance Sheets.

We record intangible assets, such as acquired contracts, customer relationships and trademark and trade name at their 
estimated fair values. We use all information available to estimate fair values including quoted market prices, if available, and 
other widely accepted valuation techniques. Certain estimates and judgments are required in the application of the techniques used 
to measure fair value of our intangible assets, including estimates of future cash flows, selling prices, replacement costs, economic 
lives  and  the  selection  of  a  discount  rate,  which  are  not  observable  in  the  market  and  represent  a  Level  3  measurement. All 
recognized intangible assets consist of contractual rights and obligations with finite lives.

102

As  of  December 31,  2016  and  2015,  the  components  of  our  intangible  assets  are  reflected  in  other  assets  on  our

Impairment Evaluation of Long-Lived Assets (Including Goodwill, 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. We use a fundamental long-term view of the power market which is based on 
long-term production volumes, price curves and operating costs together with the regulatory and environmental requirements 
within each individual market to prepare our multi-year forecast. Since we manage and market our power sales as a portfolio rather 
than at the individual power plant level or customer level within each designated market, pool or segment, we group our power 
plants based upon the corresponding market for valuation purposes. If we determine that the undiscounted cash flows from an 
asset or group of assets to be held and used are less than the associated carrying amount, or if we have classified an asset as held 
for sale, we must estimate fair value to determine the amount of any impairment loss. 

We test goodwill and all intangible assets not subject to amortization for impairments at least annually, or more frequently 
whenever an event or change in circumstances occurs that would more likely than not reduce the fair value of a reporting unit 
below its carrying amount. We test goodwill for impairment at the reporting unit level, which is identified one level below the 
Company’s  operating  segments  for  which  discrete  financial  information  is  available  and  management  regularly  reviews  the 
operating results. We perform an annual impairment assessment in the third quarter of each year, or more frequently if indicators 
of potential impairment exist, to determine whether it is more likely than not that the fair value of a reporting unit in which goodwill 
resides is less than its carrying value. For reporting units in which this assessment concludes that it is more likely than not that 
the fair value is more than its carrying value, goodwill is not considered impaired and we are not required to perform the two-step 
goodwill impairment test. Qualitative factors considered in this assessment include industry and market considerations, overall 
financial performance, and other relevant events and factors affecting the reporting unit.

For reporting units in which the impairment assessment concludes that it is more likely than not that the fair value is less 
than its carrying value, we perform the first step of the goodwill impairment test, which compares the fair value of the reporting 
unit to its carrying value. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, 
goodwill is not considered impaired and we are not required to perform additional analysis. If the carrying value of the net assets 
assigned to the reporting unit exceeds the fair value of the reporting unit, then we must perform the second step of the goodwill
impairment test to determine the implied fair value of the reporting unit’s goodwill. If we determine during the second step that 

103

 
 
the carrying value of a reporting unit’s goodwill exceeds its implied fair value, we record an impairment loss equal to the difference. 
We did not record an impairment of our goodwill during the years ended December 31, 2016 and 2015. We did not have goodwill 
recorded on our Consolidated Balance Sheet during the year ended December 31, 2014.

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 contracts, capacity prices and PPAs, 
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 effect 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 
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 effect of 
such variations could be material.

In August 2014, we executed a term sheet with Duke Energy Florida, Inc. related to our Osprey Energy Center for a new 
PPA with a term of 27 months, after which Duke Energy Florida, Inc. would purchase our Osprey Energy Center subject to an 
asset sale agreement that was executed in the fourth quarter of 2014. As a result, we conducted an impairment review of our Osprey 
Energy Center during the third quarter of 2014. We estimated fair value of our Osprey Energy Center under a modified market 
approach  using  the  discounted  cash  flows  under  the  PPA  and  the  sale  proceeds  to  be  received,  which  incorporated  a  market 
participant's fair value of the power plant. We recorded an impairment loss of approximately $123 million which was recorded as 
a  separate  line  item  on  our  Consolidated  Statements  of  Operations  for  the  year  ended  December 31,  2014.  We  recorded  an 
impairment loss of $13 million during the year ended December 31, 2016 related to a power plant in our West segment. During 
the year ended December 31, 2015, we did not record any impairment losses. 

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, 2016 and 2015, our asset retirement obligation liabilities were $53 million and $47 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.

Debt Issuance 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 
and satisfaction of an existing debt obligation, debt issuance costs are accounted for depending on whether the transaction qualifies 
as an extinguishment or modification, which requires us to either write-off the original debt issuance costs and capitalize the new 
issuance costs, or continue to amortize the original debt issuance costs and immediately expense the new issuance costs. We 
retrospectively adopted Accounting Standards Update 2015-03 in the first quarter of 2016. As a result, our debt issuance costs 
related to a recognized debt liability are presented as a direct deduction from the carrying amount of the related debt liability, 
which is consistent with the presentation of debt discounts.

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 RTO and ISO capacity auctions, variable payments for power and steam, 
which are related to generation, retail power revenues, 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, optimization and trading activities;

•  mark-to-market revenues from derivative instruments as a result of our marketing, hedging, optimization and trading 

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. 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, unless qualified as a lease, 
are recognized when contractually earned and consist of revenues received from our customers either at the market price or a 
contract price.

Revenues from sales of power to retail customers are recognized upon delivery under the accrual method, unless we 
apply derivative accounting treatment to the retail contract. See Note 8 for further discussion on our accounting for derivatives. 
Unbilled retail revenues are based upon estimates of customer usage since the date of the last meter reading provided by the ISOs 
or electric distribution companies by applying the estimated revenue per KWh by customer class to the estimated number of KWhs 
delivered but not yet billed. Estimated amounts are adjusted when actual usage is known and billed. 

Realized and Mark-to-Market 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.   

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

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

105

 
 
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 at December 31, 2016, 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 hedging 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 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 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, the cost of power purchased from third parties for sale to retail customers,  
the cost of power and natural gas purchased from third parties for our marketing, hedging and optimization activities and realized 
settlements and mark-to-market gains and losses resulting from general market price movements against certain derivative natural 
gas and power contracts including financial natural gas transactions economically hedging anticipated future power sales that 
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.

Realized and Mark-to-Market 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. 

Mark-to-Market (Gain) Loss — The changes in the mark-to-market value of natural gas-based and certain power-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 (including 
equipment  failure  and  major  maintenance),  insurance  and  property  taxes.  We  recognize  these  expenses  when  the  service  is 
performed or in the period to 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.

106

 
 
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 per Share

Basic earnings 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 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 per share.

Stock-Based Compensation

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. 
Our performance share units are measured at fair value using a Monte Carlo simulation model at each reporting date until settlement. 
We include estimated forfeitures in the calculation of stock-based compensation expense. See Note 12 for a further discussion of 
our stock-based compensation.

Treasury Stock

Treasury stock purchases are accounted for under the cost method whereby the entire cost of the acquired stock is recorded 
as treasury stock.  Upon retirement of treasury stock, the amounts in excess of par value are charged entirely to additional paid-in 
capital. See Note 14 for a further discussion of treasury stock.

New Accounting Standards and Disclosure Requirements

Revenue Recognition — In May 2014, the FASB issued Accounting Standards Update 2014-09, “Revenue from Contracts 
with Customers.” The comprehensive new revenue recognition standard will supersede all existing revenue recognition guidance. 
The core principle of the standard is that a company should recognize revenue to depict the transfer of promised goods or services 
to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or 
services. The standard also requires expanded disclosures surrounding revenue recognition. The standard allows for either full 
retrospective or modified retrospective adoption. In August 2015, the FASB deferred the effective date of Accounting Standards 
Update 2014-09 for public entities by one year, such that the standard will become effective for fiscal years and interim periods 
within those fiscal years beginning after December 15, 2017. The standard permits entities to adopt early, but only as of the original 
effective date. In March 2016, the FASB issued Accounting Standards Update 2016-08 “Principal versus Agent Considerations 
(Reporting Revenue Gross versus Net)” which clarifies implementation guidance for principal versus agent considerations in the 
new  revenue  recognition  standard.  In  May  2016,  the  FASB  issued Accounting  Standards  Update  2016-12  “Narrow-Scope 
Improvements and Practical Expedients” which addresses assessing the collectability of a contract, the presentation of sales taxes 
and other taxes collected from customers, non-cash consideration and completed contracts and contract modifications at transition. 
We are currently evaluating the effect the revenue recognition standard will have on our revenue contracts such as our PPAs and 
tolling agreements; however, we do not anticipate the adoption of this standard will have a material effect on our financial condition, 
results of operations or cash flows. 

Consolidation  —  In  February  2015,  the  FASB  issued Accounting  Standards  Update  2015-02,  “Amendments  to  the 
Consolidation Analysis.” The standard amends the consolidation model used in determining whether a reporting entity should 
consolidate the financial results of certain of its partially- and wholly-owned subsidiaries. All of our subsidiaries are subject to 
reevaluation under the revised consolidation model. Specifically, the amendments (i) modify the evaluation of whether limited 
partnerships and similar legal entities are voting interest entities or VIEs, (ii) eliminate the presumption that a general partner 
should consolidate the financial results of a limited partnership, (iii) affect the consolidation analysis of reporting entities that are 
involved with VIEs, particularly those that have fee arrangements and related party relationships and (iv) provide an exception 
for certain types of entities. This standard became effective for fiscal periods beginning after December 15, 2015, including interim 
periods within that reporting period. We adopted Accounting Standards Update 2015-02 in the first quarter of 2016 which did not 
have a material effect on our financial condition, results of operations or cash flows.

Debt  Issuance  Costs  —  In April  2015,  the  FASB  issued Accounting  Standards  Update  2015-03,  “Simplifying  the 
Presentation of Debt Issuance Costs.” The standard requires debt issuance costs related to a recognized debt liability to be presented 
in the balance sheet as a direct deduction from the carrying amount of that debt liability, which is consistent with the presentation 

107

 
of  debt  discounts.  In August  2015,  the  FASB  issued Accounting  Standards  Update  2015-15,  “Presentation  and  Subsequent 
Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements” which allows an entity to present debt issuance 
costs associated with a line-of-credit arrangement as an asset regardless of whether there are any outstanding borrowings on the 
line-of-credit arrangement. The standards became effective for fiscal years beginning after December 15, 2015, including interim 
periods within that reporting period. We retrospectively adopted Accounting Standard Updates 2015-03 and 2015-15 in the first 
quarter of 2016 which resulted in a $152 million reclassification of debt issuance costs from other assets to debt, net of current 
portion on our Consolidated Condensed Balance Sheet at December 31, 2015.

Cloud Computing Arrangements — In April 2015, the FASB issued Accounting Standards Update 2015-05, “Customer’s 
Accounting  for  Fees  Paid  in  a  Cloud  Computing Arrangement.” The  standard  provides  guidance  regarding  whether  a  cloud 
computing arrangement represents a software license or a service contract. The standard became effective for fiscal years beginning 
after December 15, 2015, including interim periods. We adopted Accounting Standards Update 2015-05 in the first quarter of 2016 
which did not have a material effect on our financial condition, results of operations or cash flows.

Inventory — In July 2015, the FASB issued Accounting Standards Update 2015-11, “Simplifying the Measurement of 
Inventory.” The standard changes the inventory valuation method from the lower of cost or market to the lower of cost or net 
realizable value for inventory valued under the first-in, first-out or average cost methods. The standard is effective for fiscal years 
beginning after December 15, 2016, including interim periods and requires prospective adoption with early adoption permitted. 
We do not anticipate a material effect on our financial condition, results of operations or cash flows as a result of adopting this 
standard.

Leases — In February 2016, the FASB issued Accounting Standards Update 2016-02, “Leases.” The comprehensive new 
lease standard will supersede all existing lease guidance. The standard requires that a lessee should recognize a right-to-use asset 
and a lease liability for substantially all operating leases based on the present value of the minimum rental payments. Entities may 
make an accounting policy election to not recognize lease assets and liabilities for leases with a term of 12 months or less. For 
lessors, the accounting for leases remains substantially unchanged. The standard also requires expanded disclosures surrounding 
leases. The  standard  is  effective  for  fiscal  periods  beginning  after  December  15,  2018,  including  interim  periods  within  that 
reporting  period  and  requires  modified  retrospective  adoption  with  early  adoption  permitted.  We  have  completed  our  initial 
evaluation of the standard and believe that the key changes that will affect us relate to our accounting for operating leases that are 
currently off-balance sheet and tolling contracts which we currently account for as operating leases. Additionally, we are evaluating 
the potential effects of the removal of the real estate guidance currently applicable to lessors that will be abrogated under Accounting 
Standards Update 2014-09, “Revenue from Contracts with Customers.” We are also considering electing the practical expedient 
in our implementation of the standard.

Stock-Based Compensation — In March 2016, the FASB issued Accounting Standards Update 2016-09, “Improvements 
to  Employee  Share-Based  Payment  Accounting.”  The  standard  applies  to  several  aspects  of  accounting  for  stock-based 
compensation including the recognition of excess tax benefits and deficiencies and their related presentation in the statement of 
cash flows as well as accounting for forfeitures. The standard also requires that shares withheld to satisfy tax withholding obligations 
associated with the vesting of restricted stock awarded to employees be presented as a financing activity in the statement of cash 
flows. The standard is effective for fiscal years beginning after December 15, 2016, including interim periods and allows for 
prospective, retrospective or modified retrospective adoption, depending on the area covered in the standard, with early adoption 
permitted. We early adopted Accounting Standards Update 2016-09 in the third quarter of 2016. The cumulative-effect adjustment 
to accumulated deficit for all excess tax benefits not previously recognized as of the beginning of the year is substantially offset 
by a corresponding change in the valuation allowance. The implementation of Accounting Standards Update 2016-09 did not have 
a material effect on our financial condition, results of operations or cash flows.

Statement of Cash Flows — In August 2016, the FASB issued Accounting Standards Update 2016-15, “Classification of 
Certain Cash Receipts and Cash Payments.” The standard addresses several matters of diversity in practice in how certain cash 
receipts  and  cash  payments  are  presented  and  classified  in  the  statement  of  cash  flows  including  the  presentation  of  debt 
extinguishment costs and distributions received from equity method investments. The standard is effective for fiscal years beginning 
after December 15, 2017, including interim periods and allows for retrospective adoption with early adoption permitted. We do 
not anticipate a material effect on our financial condition, results of operations or cash flows as a result of adopting this standard.

Restricted Cash — In November 2016, the FASB issued Accounting Standards Update 2016-18, “Restricted Cash.” The 
standard requires restricted cash to be included with cash and cash equivalents when reconciling the beginning and ending amounts 
in the statement of cash flows and also requires disclosures regarding the nature of restrictions on cash, cash equivalents and 
restricted cash. The standard is effective for fiscal years beginning after December 15, 2017, including interim periods and requires 

108

 
 
 
for retrospective adoption with early adoption permitted. We do not anticipate a material effect on our financial condition, results 
of operations or cash flows as a result of adopting this standard.

Intangibles  —  Goodwill  and  Other  —  In  January  2017,  the  FASB  issued Accounting  Standards  Update  2017-04, 
“Simplifying the Test for Goodwill Impairment.” The standard eliminates the second step in the goodwill impairment test which 
requires an entity to determine the implied fair value of the reporting unit’s goodwill. Instead, an entity should recognize an 
impairment loss if the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, 
with the impairment loss not to exceed the amount of goodwill allocated to the reporting unit. The standard is effective for annual 
and interim goodwill impairment tests conducted in fiscal years beginning after December 15, 2019, with early adoption permitted. 
We do not anticipate a material effect on our financial condition, results of operations or cash flows as a result of adopting this 
standard.

Acquisitions and Divestitures 

Acquisition of Calpine Solutions, formerly Noble Solutions

On December 1, 2016, through our indirect, wholly-owned subsidiaries Calpine Energy Services Holdco II, LLC and 
Calpine Energy Financial Holdings, LLC, we completed the purchase of Calpine Solutions, formerly Noble Solutions, along with 
a  swap  contract  from  Noble Americas  Gas  &  Power  Corp.  and  Noble  Group  Limited  for  approximately  $800  million  plus 
approximately $350 million of net working capital. We recovered approximately $250 million in cash subsequent to closing and 
expect to recover an additional approximately $200 million through collateral synergies and the runoff of acquired legacy hedges, 
substantially within the first year. Calpine Solutions is a commercial and industrial retail electricity provider with customers in 
19 states in the U.S., including presence in California, Texas, the Mid-Atlantic and Northeast, where our wholesale power generation 
fleet is primarily concentrated. The acquisition of this large direct energy sales platform is consistent with our stated goal of getting 
closer to our end-use customers and expands our retail customer base, complementing our existing retail business while providing 
us a valuable sales channel for reaching a much greater portion of the load we seek to serve. We funded the acquisition with a 
combination of cash on hand and debt financing. The results of Calpine Solutions are reflected in the segment which corresponds 
with the geographic area in which the retail sales occur. 

The following table summarizes the consideration paid for Calpine Solutions as well as the preliminary determination 

of the identifiable assets acquired and liabilities assumed at the December 1, 2016 acquisition date (in millions):

We recorded goodwill of $162 million, all of which is deductible for tax purposes, in connection with the acquisition of 
Calpine Solutions which represent the excess of the purchase price over the fair values of Calpine Solution’s assets and liabilities. 
For the goodwill acquired, we allocated $68 million to our West segment, $15 million to our Texas segment and $79 million to 
our East segment.

The  revenue  and  earnings  of  Calpine  Solutions  since  its  acquisition  on  December  1,  2016  are  not  material  to  our

On  January  17,  2017,  we,  through  an  indirect,  wholly-owned  subsidiary,  completed  the  purchase  of  100%  of  the 
outstanding limited liability company membership interests in North American Power for approximately $105 million, excluding 
working capital and other adjustments. North American Power is a growing retail energy supplier for homes and small businesses 
and is primarily concentrated in the Northeast U.S. where Calpine has a substantial power generation presence and where Champion 
Energy has a substantial retail sales footprint that will be enhanced by the addition of North American Power, which will be 
integrated into our Champion Energy retail platform. We funded the acquisition with cash on hand and the purchase price will be 
primarily allocated to goodwill and intangible assets. The pro forma incremental effect of North American Power on our results 
of operations for each of the years ended December 31, 2016 and 2015 is not material.

Acquisition of Granite Ridge Energy Center

On February 5, 2016, we, through our indirect, wholly-owned subsidiary Calpine Granite Holdings, LLC, completed the 
purchase of Granite Ridge Energy Center, a power plant with a nameplate capacity of 745 MW (summer peaking capacity of 695
MW), from Granite Ridge Holdings, LLC, for approximately $500 million, excluding working capital and other adjustments. The 
addition of this modern, efficient, natural gas-fired, combined-cycle power plant increased capacity in our East segment, specifically 
the constrained New England market. Beginning operations in 2003, Granite Ridge Energy Center is located in Londonderry, New 
Hampshire and features two combustion turbines, two heat recovery steam generators and one steam turbine. We funded the 
acquisition with a combination of cash on hand and our 2023 First Lien Term Loan obtained in the fourth quarter of 2015, and 
the purchase price was primarily allocated to property, plant and equipment. The pro forma incremental effect of Granite Ridge 
Energy Center on our results of operations for each of the years ended December 31, 2016 and 2015 is not material.

Acquisition of Champion Energy

On October 1, 2015, we, through our indirect, wholly-owned subsidiary Calpine Energy Services Holdco, LLC, completed 
the purchase of Champion Energy Marketing, LLC from a subsidiary of Crane Champion Holdco, LLC, which owned a 75%
interest, and EDF Trading North America, LLC, which owned a 25% interest, for approximately $240 million, excluding working 
capital adjustments. The addition of this well-established retail sales organization is consistent with our stated goal of getting 
closer to our end-use customers and provides us a valuable sales channel for directly reaching a much greater portion of the load 
we seek to serve. The purchase price was funded with cash on hand and any excess of the purchase price over the fair values of 
Champion Energy’s assets and liabilities was recorded as goodwill; however, the goodwill we recorded as a result of this acquisition 
was immaterial. The purchase price allocation was finalized during the third quarter of 2016 which did not result in any material 
adjustments. The pro forma incremental effect of Champion Energy on our results of operations for each of the years ended 
December 31, 2015 and 2014 is not material.

Acquisition of Fore River Energy Center

On November 7, 2014, we, through our indirect, wholly-owned subsidiary Calpine Fore River Energy Center, LLC, 
completed the purchase of Fore River Energy Center, a power plant with a capacity of 731 MW, and related plant inventory from 
a subsidiary of Exelon Corporation, for approximately $530 million, excluding working capital adjustments. The addition of this 
modern, efficient, natural gas-fired, combined-cycle power plant increased capacity in our East segment, specifically the constrained 
New England market. Built in 2003, Fore River Energy Center is located in North Weymouth, Massachusetts and features two 
combustion turbines, two heat recovery steam generators and one steam turbine. Both turbines feature dual-fuel capability that 
will enable them to run on either natural gas or fuel oil, depending on market conditions. The purchase price was funded with cash 
on hand and primarily allocated to property, plant and equipment. The purchase price allocation was finalized during the third 
quarter of 2015 which did not result in any material adjustments or the recognition of goodwill. The pro forma incremental effect 
of Fore River Energy Center on our results of operations for the year ended December 31, 2014 is not material.

Acquisition of Guadalupe Energy Center

On February 26, 2014, we, through our indirect, wholly-owned subsidiary Calpine Guadalupe GP, LLC, completed the 
purchase of a power plant owned by MinnTex Power Holdings, LLC with a capacity of 1,000 MW, for approximately $625 million, 
excluding working capital adjustments. The addition of this modern, natural gas-fired, combined-cycle power plant increased 
capacity in our Texas segment, which is one of our core markets. The 110-acre site, located in Guadalupe County, Texas, which 
is northeast of San Antonio, Texas, includes two 525 MW generation blocks, each consisting of two GE 7FA combustion turbines, 
two heat recovery steam generators and one GE steam turbine. We also paid $15 million to acquire rights to an advanced development 
opportunity for an approximately 400 MW quick-start, natural gas-fired peaker. We funded the acquisition with $425 million in 
incremental CCFC Term Loans and cash on hand. See Note 6 for a further description of the incremental CCFC Term Loans. The 
purchase price was primarily allocated to property, plant and equipment and was finalized during the third quarter of 2014 which 
did not result in any material adjustments to the preliminary purchase price allocation nor the recognition of any goodwill. The 
pro forma incremental effect of Guadalupe Energy Center on our results of operations for the year ended December 31, 2014 is 
not material.

Sale of Osprey Energy Center

On January 3, 2017, we completed the sale of our Osprey Energy Center to Duke Energy Florida, Inc. for approximately 
$166 million, excluding working capital and other adjustments. This transaction supports our effort to divest non-core assets 
outside our strategic concentration. 

Sale of Mankato Power Plant

On October 26, 2016, we, through our indirect, wholly-owned subsidiaries, New Steamboat Holdings, LLC and Mankato 
Holdings, LLC, completed the sale of our Mankato Power Plant, a 375 MW natural gas-fired, combined-cycle power plant and 
345 MW expansion project under advanced development located in Minnesota, to Southern Power Company, a subsidiary of 
Southern Company, for $396 million, excluding working capital and other adjustments. This transaction supports our effort to 
divest non-core assets outside our strategic concentration. We used the proceeds from the sale to partially fund the Calpine Solutions, 
formerly Noble Solutions, acquisition and for other corporate purposes. We recorded a gain on sale of assets, net of approximately 
$157 million during the fourth quarter of 2016, and our federal and state NOLs almost entirely offset the projected taxable gain 
from the sale. 

Sale of South Point Energy Center

On April 1, 2016, we entered into an asset sale agreement for the sale of substantially all of the assets comprising our 
South Point Energy Center to Nevada Power Company d/b/a NV Energy for approximately $76 million plus the assumption by 
the purchaser of existing transmission capacity contracts with a future net present value payment obligation of approximately $112 
million, approximately $9 million in remaining tribal lease costs and approximately $21 million in near-term repairs, maintenance 
and capital improvements to restore the power plant to full capacity. The sale is subject to certain conditions precedent, as well 
as  federal  and  state  regulatory  approvals.  The  natural  gas-fired,  combined-cycle  plant  is  located  on  the  Fort  Mojave  Indian 
Reservation in Mohave Valley, Arizona, and features a summer peaking capacity of 504 MW. This transaction supports our effort 
to divest non-core assets outside our strategic concentration. In December 2016, the Nevada Public Utility Commission issued an 
order rejecting the asset sale agreement. In January 2017, Nevada Power Company filed a motion for reconsideration of this order. 
In February 2017, the FERC approved Nevada Power Company’s acquisition of the South Point Energy Center. However, on 
February 8, 2017, the Nevada Public Utility Commission denied Nevada Power Company’s purchase of the South Point Energy 
Center. Nevada Power Company has the right to appeal this decision. We are also currently assessing our options; however, we 

111

 
 
do not anticipate that the denial of the sale by the Nevada Public Utility Commission will have a material effect on our financial 
condition, results of operations or cash flows.

Sale of Six Power Plants

On July 3, 2014, we completed the sale of six of our power plants in our East segment to NatGen Southeast Power LLC, 
a wholly-owned subsidiary of LS Power Equity Partners III. The purchase and sale agreement, dated April 17, 2014, stipulates 
the sale of 100% of the limited liability company interests in (i) Mobile Energy LLC, (ii) Santa Rosa Energy Center, LLC, (iii) 
Carville Energy, LLC, (iv) Decatur Energy Center, LLC, (v) Columbia Energy LLC and (vi) Calpine Oneta Power, LLC and 
thereby sell assets comprising 3,498 MW of combined-cycle generation capacity in Oklahoma, Louisiana, Alabama, Florida and 
South Carolina for a sale price of approximately $1.57 billion in cash, plus approximately $2 million for working capital and other 
adjustments at closing. The divestiture of these power plants has better aligned our asset base with our strategic focus on competitive 
wholesale markets. 

We recorded a gain on sale of assets, net of approximately $753 million during the third quarter of 2014 and used existing 
federal and state NOLs to almost entirely offset the projected taxable gains from the sale. The sale of the six power plants did not 
meet the criteria for treatment as discontinued operations.

The six power plants included in the transaction are as follows:

Total depreciation expense, including amortization of leased assets, recorded for the years ended December 31, 2016, 

2015 and 2014, was $628 million, $595 million and $591 million, respectively.

We have various debt instruments that are collateralized by our property, plant and equipment. See Note 6 for a discussion 

of such instruments.

Buildings, Machinery and Equipment

This component primarily includes power plants and related equipment. Included in buildings, machinery and equipment 

are assets under capital leases. See Note 6 for further information regarding these assets under capital leases.

Geothermal Properties

This component primarily includes power plants and related equipment associated with our Geysers Assets.

Other

This component primarily includes software and emission reduction credits that are power plant specific and not available 

to be sold.

Capitalized Interest

The total amount of interest capitalized was $21 million, $15 million and $19 million for the years ended December 31, 

2016, 2015 and 2014, respectively.

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, 2016. 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. 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 affect 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 almost 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  effect  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 almost 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

113

• 

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 affect 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 9,491 MW and 10,266 MW, 
at December 31, 2016 and 2015, 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. Other than amounts contractually 
required, we provided support to these VIEs in the form of cash and other contributions of $115 million, $4 million and $47 million 
for the years ended December 31, 2016, 2015 and 2014, respectively.

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 and Investments in Unconsolidated Subsidiaries

We have a 50% partnership interest in Greenfield LP and in Whitby. Greenfield LP and Whitby are VIEs; however, we 
do not have the power to direct the most significant activities of these entities and therefore do not consolidate them. Greenfield 
LP is a limited partnership between certain subsidiaries of ours and of Mitsui & Co., Ltd., which operates the Greenfield Energy 
Centre, a 1,038 MW natural gas-fired, combined-cycle power plant located in Ontario, Canada. We and Mitsui & Co., Ltd. each 
hold a 50% interest in Greenfield LP. Whitby is a limited partnership between certain of our subsidiaries 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.

In December 2016, we acquired Calpine Receivables, a bankruptcy remote entity created for the special purpose of 
purchasing trade accounts receivable from Calpine Solutions under the Accounts Receivable Sales Program. Calpine Receivables 
is a VIE as we have determined that we do not have the power to direct the activities of the VIE that most significantly affect the 
VIE’s economic performance nor the obligation to absorb losses or receive benefits from the VIE. Accordingly, we have determined 
that we are not the primary beneficiary of Calpine Receivables as we do not have the  power to affect its financial performance 
as the unaffiliated financial institutions that purchase the receivables from Calpine Receivables control the selection criteria of 
the receivables sold and appoint the servicer of the receivables which controls management of default. Thus, we do not consolidate 
Calpine Receivables in our Consolidated Financial Statements and use the equity method of accounting to record our net interest 
in Calpine Receivables. 

We account for these entities under the equity method of accounting and include our net equity interest in investments 
in unconsolidated subsidiaries on our Consolidated Balance Sheets. At December 31, 2016 and 2015, our equity method investments 
included on our Consolidated Balance Sheets were comprised of the following (in millions):

Our risk of loss related to our investments in Greenfield LP, Whitby and Calpine Receivables 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, 2016 and 2015, Greenfield LP’s debt was approximately $259 million and $269 million, respectively, and based 
on our pro rata share of our investment in Greenfield LP, our share of such debt would be approximately $130 million and $135 
million at December 31, 2016 and 2015, respectively.

Our equity interest in the net income from our investments in unconsolidated subsidiaries for the years ended December 31, 
2016, 2015 and 2014, is recorded in (income) from unconsolidated subsidiaries. We did not have any income or receive any 
distributions from our investment in Calpine Receivables for the year ended December 31, 2016. The following table sets forth 
details of our (income) from unconsolidated subsidiaries and distributions for the years indicated (in millions):

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) 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.

Debt

We retrospectively adopted Accounting Standards Update 2015-03 in the first quarter of 2016. As a result, we recast our 
Consolidated Balance Sheet at December 31, 2015 resulting in a $152 million reclassification of debt issuance costs from other 
assets to debt, net of current portion. Our debt at December 31, 2016 and 2015, was as follows (in millions):

(1)  Our weighted average interest rate calculation includes the amortization of debt issuance costs.

In February 2015, we issued $650 million in aggregate principal amount of 5.5% senior unsecured notes due 2024 in a 
public offering. The 2024 Senior Unsecured Notes bear interest at 5.5% per annum with interest payable semi-annually on February 
1 and August 1 of each year, beginning on August 1, 2015. The 2024 Senior Unsecured Notes were issued at par, mature on 
February 1, 2024 and contain substantially similar covenant, qualifications, exceptions and limitations as our 2023 Senior Unsecured 
Notes and 2025 Senior Unsecured Notes. We used the net proceeds received from the issuance of our 2024 Senior Unsecured 
Notes to replenish cash on hand used for the acquisition of Fore River Energy Center in the fourth quarter of 2014, to repurchase 
approximately $147 million of our 2023 First Lien Notes and for general corporate purposes. We recorded approximately $9 
million in debt issuance costs related to the issuance of our 2024 Senior Unsecured Notes and approximately $19 million in debt 
extinguishment costs during the first quarter of 2015 related to the partial repurchase of our 2023 First Lien Notes.

On July 22, 2014, we issued $1.25 billion in aggregate principal amount of 5.375% senior unsecured notes due 2023 and 
$1.55 billion in aggregate principal amount of 5.75% senior unsecured notes due 2025 in a public offering. The 2023 Senior 
Unsecured Notes bear interest at 5.375% per annum and the 2025 Senior Unsecured Notes bear interest at 5.75% per annum, in 
each case payable semi-annually on April 15 and October 15 of each year, beginning on April 15, 2015. The 2023 Senior Unsecured 
Notes mature on January 15, 2023 and the 2025 Senior Unsecured Notes mature on January 15, 2025. Our Senior Unsecured Notes 
were issued at par.

Our Senior Unsecured Notes are:

• 

• 

• 

• 

general unsecured obligations of Calpine;

rank equally in right of payment with all of Calpine’s existing and future senior indebtedness;

effectively subordinated to Calpine’s secured indebtedness to the extent of the value of the collateral securing such 
indebtedness;

structurally subordinated to any existing and future indebtedness and other liabilities of Calpine’s subsidiaries; and

116

 
 
• 

senior in right of payment to any of Calpine’s subordinated indebtedness.

We used the net proceeds received from the issuance of our 2023 Senior Unsecured Notes and 2025 Senior Unsecured 
Notes, together with cash on hand, to repurchase our outstanding 2019 First Lien Notes, 2020 First Lien Notes and 2021 First 
Lien Notes during the third quarter of 2014. We recorded approximately $42 million in debt issuance costs and approximately 
$340 million in debt extinguishment costs during the third quarter of 2014 related to the repayment of our 2019 First Lien Notes, 
2020 First Lien Notes and 2021 First Lien Notes.

(1)  Our weighted average interest rate calculation includes the amortization of debt issuance costs and debt discount.

(2)  On December 21, 2016, we repriced our 2023 First Lien Term Loans by lowering the margin over LIBOR by 0.25% to 

2.75% and extended the maturity of our 2024 First Lien Term Loan From May 2022 to January 2024.

On May 31, 2016, we entered into a $562 million first lien senior secured term loan which bears interest, at our option, 
at either (i) the Base Rate, equal to the highest of (a) the Federal Funds Effective Rate plus 0.50% per annum, (b) the Prime Rate 
or (c) the Eurodollar Rate for a one month interest period plus 1.0% (in each case, as such terms are defined in the New 2023 First 
Lien Term Loan credit agreement), plus an applicable margin of 2.00%, or (ii) LIBOR plus 2.75% per annum (with no LIBOR 
floor) and matures on May 31, 2023. An aggregate amount equal to 0.25% of the aggregate principal amount of the New 2023 
First Lien Term Loans is payable at the end of each quarter with the remaining balance payable on the maturity date. We paid an 
upfront fee of an amount equal to 1.0% of the aggregate principal amount of the New 2023 First Lien Term Loan, which is structured 
as original issue discount and recorded approximately $11 million in debt issuance costs during the second quarter of 2016 related 
to the issuance of our New 2023 First Lien Term Loan. The New 2023 First Lien Term Loan contains substantially similar covenants, 
qualifications, exceptions and limitations as other First Lien Term Loans and the First Lien Notes. We used the proceeds from the 
New 2023 First Lien Term Loan and the 2026 First Lien Notes, discussed below, to repay the 2019 and 2020 First Lien Term 
Loans and recorded $15 million in debt extinguishment costs during the second quarter of 2016 associated with the repayment.

On December 1, 2016, we entered into a $550 million first lien senior secured term loan which bears interest, at our 
option, at either (i) the Base Rate, equal to the highest of (a) the Federal Funds Effective Rate plus 0.50% per annum, (b) the Prime 
Rate or (c) the Eurodollar Rate for a one month interest period plus 1.0% (in each case, as such terms are defined in the 2017 First 
Lien Term Loan credit agreement), plus an applicable margin of 0.75%, or (ii) LIBOR plus 1.75% per annum (with no LIBOR 
floor) and matures on November 30, 2017. An aggregate amount equal to 0.25% of the aggregate principal amount of the 2017 
First Lien Term Loans is payable on June 30, 2017 with the remaining balance payable on the maturity date. We paid an upfront 
fee of an amount equal to 1.0% of the aggregate principal amount of the 2017 First Lien Term Loan, which is structured as original 
issue discount and recorded approximately $9 million in debt issuance costs during the fourth quarter of 2016 related to the issuance 
of  our  2017  First  Lien  Term  Loan.  The  2017  First  Lien  Term  Loan  contains  substantially  similar  covenants,  qualifications, 
exceptions and limitations as other First Lien Term Loans and the First Lien Notes. We used the proceeds from the 2017 First Lien 
Term Loan to partially fund the acquisition of Calpine Solutions, formerly Noble Solutions. 

On May 28, 2015, we entered into a $1.6 billion first lien senior secured term loan which bears interest, at our option, 
at either (i) the base rate, equal to the highest of (a) the Federal Funds Effective Rate plus 0.5% per annum, (b) the Prime Rate or 
(c) the Eurodollar Rate for a one month interest period plus 1.0% (in each case, as such terms are defined in the 2024 First Lien 
Term Loan credit agreement, plus an applicable margin of 1.75%, or (ii) LIBOR plus 2.75% per annum subject to a LIBOR floor 

117

 
 
of 0.75% and matures on January 15, 2024. An aggregate amount equal to 0.25% of the aggregate principal amount of the 2024 
First Lien Term Loan is payable at the end of each quarter with the remaining balance payable on the maturity date. The 2024 
First Lien Term Loan contains substantially similar covenants, qualifications, exceptions and limitations as other First Lien Term 
Loans and the First Lien Notes. We used the net proceeds received, together with operating cash on hand, to repay the 2018 First 
Lien Term Loans. 

We accounted for this transaction as a debt modification rather than an extinguishment of debt and, accordingly, did not 
record any debt extinguishment costs associated with the repayment of our 2018 First Lien Term Loans. However, in accordance 
with  the  accounting  guidance  for  debt  modification  and  extinguishment,  we  recorded  approximately  $13  million  in  debt 
modification costs associated with issuance costs and approximately $6 million in debt issuance costs related to the 2024 First 
Lien Term Loan during the second quarter of 2015.

On December 15, 2015, we entered into a $550 million first lien senior secured term loan which bears interest, at our 
option, at either (i) the Base Rate, equal to the highest of (a) the Federal Funds Effective Rate plus 0.50% per annum, (b) the Prime 
Rate or (c) the Eurodollar Rate for a one month interest period plus 1.0% (in each case, as such terms are defined in the 2023 First 
Lien Term Loan credit agreement), plus an applicable margin of 2.00%, or (ii) LIBOR plus 2.75% per annum with no LIBOR 
floor and matures on January 15, 2023. An aggregate amount equal to 0.25% of the aggregate principal amount of the 2023 First 
Lien Term Loans is payable at the end of each quarter with the remaining balance payable on the maturity date. We paid an upfront 
fee of an amount equal to 1.0% of the aggregate principal amount of the 2023 First Lien Term Loan, which is structured as original 
issue discount and recorded approximately $12 million  in debt issuance costs during the fourth quarter of 2015 related to the 
issuance of our 2023 First Lien Term Loan. The 2023 First Lien Term Loan contains substantially similar covenants, qualifications, 
exceptions and limitations as other First Lien Term Loans and the First Lien Notes. We utilized $325 million of the proceeds 
received, together with cash on hand, to purchase Granite Ridge Energy Center and used the remaining proceeds to repay project 
and corporate debt and for general corporate purposes. The 2019 First Lien Term Loan and 2020 First Lien Term Loan carried 
substantially similar terms, covenants, qualifications, exceptions and limitations as our 2023 First Lien Term Loan.

On February 3, 2017, we entered into a $400 million first lien senior secured term loan which bears interest, at our option, 
at either (i) the Base Rate, equal to the highest of (a) the Federal Funds Effective Rate plus 0.50% per annum, (b) the Prime Rate 
or (c) the Eurodollar Rate for a one month interest period plus 1.0% (in each case, as such terms are defined in the New 2019 First 
Lien Term Loan credit agreement), plus an applicable margin of 0.75%, or (ii) LIBOR plus 1.75% per annum (with no LIBOR 
floor) and matures on December 31, 2019. An aggregate amount equal to 0.25% of the aggregate principal amount of the New 
2019 First Lien Term Loans is payable at the end of each quarter (beginning with the quarter ending June 2017) with the remaining 
balance payable on the maturity date. We paid an upfront fee of an amount equal to 1.0% of the aggregate principal amount of the 
New 2019 First Lien Term Loan, which is structured as original issue discount and expect to record approximately $8 million in 
debt issuance costs during the first quarter of 2017 related to the issuance of our New 2019 First Lien Term Loan. The New 2019 
First Lien Term Loan contains substantially similar covenants, qualifications, exceptions and limitations as other First Lien Term 
Loans and the First Lien Notes. We used the proceeds from the New 2019 First Lien Term Loan, together with cash on hand, to 
redeem the remaining outstanding 2023 First Lien Notes and expect to record approximately $21 million in debt extinguishment 
costs during the first quarter of 2017 associated with the redemption of the 2023 First Lien Notes.

In December 2016, we used cash on hand to redeem 10% of the original aggregate principal amount of our 2023 First Lien 
Notes, plus accrued and unpaid interest. During the fourth quarter of 2016, we recorded approximately $5 million in debt 
extinguishment costs related to the partial repurchase of our 2023 First Lien Notes.

(3)  On February 3, 2017, we issued a notice of redemption to repay the remaining $453 million of our outstanding 2023 First 
Lien  Notes  using  cash  on  hand  along  with  the  proceeds  from  the  New  2019 First  Lien  Term  Loan  which  contains  a 
substantially lower variable rate of LIBOR plus 1.75% per annum. 

On May 31, 2016, we issued $625 million in aggregate principal amount of 5.25% senior secured notes due 2026 in a 
private placement. Our 2026 First Lien Notes bear interest at 5.25% payable semi-annually on June 1 and December 1 of each 
year, beginning on December 1, 2016. Our 2026 First Lien Notes mature on June 1, 2026 and contain substantially similar covenants, 
qualifications, exceptions and limitations as our First Lien Notes. We recorded approximately $9 million in debt issuance costs 
during the second quarter of 2016 related to the issuance of our 2026 First Lien Notes.

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 
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 May 3, 2013, CCFC entered into a credit agreement providing for a first lien senior secured term loan facility comprised 
of (i) a $900 million 7-year term loan and (ii) a $300 million 8.5-year term loan. The CCFC Term Loans bear interest, at CCFC’s 
option, at either (i) the Base Rate, equal to the higher of the Federal Funds Effective Rate plus 0.50% per annum or the Prime Rate 
(as such terms are defined in the Credit Agreement), plus an applicable margin of (a) 1.25% per annum with respect to the 7-year 
term loan and (b) 1.50% per annum with respect to the 8.5-year term loan, or (ii) LIBOR plus (a) 2.25% per annum with respect 
to the 7-year term loan and (b) 2.50% per annum with respect to the 8.5-year term loan (in each case subject to a LIBOR floor of 
0.75%). The term loans were offered to investors at an issue price equal to 99.75% of face value.

An amount equal to 0.25% of the aggregate principal amount of the CCFC Term Loans are payable at the end of each 
quarter commencing in September 2013, with the remaining balance payable on the relevant maturity date (May 3, 2020 with 
respect to the 7-year term loan and January 31, 2022 with respect to the 8.5-year term loan). CCFC may elect from time to time 
to convert all or a portion of the CCFC Term Loans from LIBOR loans to Base Rate loans or vice versa. In addition, CCFC may 
at any time, and from time to time, prepay the term loans, in whole or in part, without premium or penalty, upon irrevocable notice 
to the administrative agent. 

In February 2014, we executed an amendment to the credit agreement associated with the CCFC Term Loans, which 
allowed us to issue $425 million in incremental CCFC Term Loans to fund a portion of the purchase price paid in connection with 
the closing of our acquisition of Guadalupe Energy Center on February 26, 2014. Guadalupe Energy Center was purchased by 
Calpine Guadalupe GP, LLC, a wholly-owned subsidiary of CCFC. The incremental term loans carry substantially the same terms 
and conditions as the $300 million in aggregate principal amount of CCFC Term Loans issued in June 2013. The incremental term 
loans were offered to investors at an issue price equal to 98.75% of face value.

The CCFC Term Loans are secured by certain real and personal property of CCFC consisting primarily of seven natural 
gas-fired power plants. The CCFC Term Loans are not guaranteed by Calpine Corporation and are without recourse to Calpine 
Corporation or any of our non-CCFC subsidiaries or assets; however, CCFC generates the majority of its cash flows from an 
intercompany  tolling  agreement  with  Calpine  Energy  Services,  L.P.  and  has  various  service  agreements  in  place  with  other 
subsidiaries of Calpine Corporation.

(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 35 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, 2016 and 2015, the asset balances for the leased assets totaled approximately $864 million and $877 
million with accumulated amortization of $404 million and $390 million, respectively. Amortization of assets under capital leases 
is recorded in depreciation and amortization expense on our Consolidated Statements of Operations. See Note 15 for discussion 
of capital leases guaranteed by Calpine Corporation.

On February 8, 2016, we amended our Corporate Revolving Facility, extending the maturity by two years to June 27, 
2020, and increasing the capacity by an additional $178 million to $1,678 million through June 27, 2018, reverting back to $1,520 
million through the maturity date. Further, we increased the letter of credit sublimit by $250 million to $1.0 billion and extended 
the maturity by two years to June 27, 2020.

On December 1, 2016, we amended our Corporate Revolving Facility, increasing the capacity by $112 million to $1,790 

million for the full term through June 27, 2020. 

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 1.00% to 1.25% 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 2.00% to 2.25%. 
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 

121

 
 
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 0.25% to 0.50% on the unused amount of commitments under the Corporate Revolving 
Facility. 

The Corporate Revolving Facility does not contain any requirements for mandatory prepayments, except in the case of 
certain designated asset sales in excess of $3.0 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 is guaranteed and secured by certain of our current domestic subsidiaries 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 have a $300 million letter of credit facility related to CDHI which matures on January 2, 2018. 

Fair Value of Debt

Excludes a lease that is accounted for as a failed sale-leaseback transaction under U.S. GAAP.

We measure the fair value of our Senior Unsecured Notes, First Lien Term Loans, First Lien Notes and CCFC Term 
Loans 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.

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 and other interest-bearing 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. We do not have any cash equivalents 
invested in institutional prime money market funds which require use of a floating net asset value and are subject to liquidity fees 
and redemption restrictions. Our cash equivalents are classified within level 1 of the fair value hierarchy.

122

 
 
Margin Deposits and Margin Deposits Posted with Us by Our Counterparties — Margin deposits and margin deposits 
posted with us by our counterparties represent cash collateral paid between our counterparties and us to support our commodity 
contracts. Our margin deposits and margin deposits posted with us 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 and customers for energy commodity derivatives; and 
prevailing interest rates for our interest rate hedging instruments. 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 customers and the effect 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 power and natural gas swaps, futures and options traded 

on the NYMEX or Intercontinental Exchange.

Our level 2 fair value derivative instruments primarily consist of interest rate hedging instruments and OTC power and 
natural gas forwards for which market-based pricing inputs in the principal or most advantageous market are representative of 
executable prices for market participants. These inputs are observable at commonly quoted intervals for substantially the full term 
of the instruments. In certain instances, our level 2 derivative instruments may utilize models to measure fair value. These models 
are 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 primarily for the sale of power to both  
wholesale counterparties and retail customers. Complex or structured transactions are tailored to 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 effect 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. 
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.

For a definition of the different levels in the fair value hierarchy, see Item 7 “Management’s Discussion and Analysis of 

Financial Condition and Results of Operations — Application of Critical Accounting Policies — Fair Value Measurements”.

123

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, 2016 and 2015, by level within the fair value hierarchy:

At December 31, 2016 and 2015, the derivative instruments classified as level 3 primarily included commodity contracts, 
which are classified as level 3 because the contract terms relate to a delivery location or tenor for which observable market rate 
information is not available. The fair value of the net derivative position classified as level 3 is predominantly driven by market 
commodity prices. The following table presents quantitative information for the unobservable inputs used in our most significant

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, fuel oil, 
environmental products 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.

We also engage in limited trading activities related to our commodity derivative portfolio as authorized by our Board of 
Directors and monitored by our Chief Risk Officer and Risk Management Committee of senior management. These transactions 
are executed primarily for the purpose of providing improved price and price volatility discovery, greater market access, and 
profiting from our market knowledge, all of which benefit our asset hedging activities. Our trading results were not material for 
the years ended December 31, 2016, 2015 and 2014.

Interest Rate Hedging Instruments — A portion of our debt is indexed to base rates, primarily LIBOR. We have historically 
used interest rate hedging instruments to adjust the mix between fixed and variable rate debt to hedge our interest rate risk for 
potential adverse changes in interest rates. As of December 31, 2016, the maximum length of time over which we were hedging 
using interest rate hedging instruments designated as cash flow hedges was 9 years.

As of December 31, 2016 and 2015, the net forward notional buy (sell) position of our outstanding commodity derivative 
instruments that did not qualify or were not designated under the normal purchase normal sale exemption and our interest rate 
hedging instruments were as follows (in millions):

(1)  We entered into interest rate hedging instruments during the second quarter of 2016 to hedge approximately $2.5 billion of 
variable rate corporate debt for 2017 through 2019 which effectively places a ceiling on LIBOR at rates varying from 1.44%
to 1.8125% for hedged interest payments. See Note 6 for a further discussion of our First Lien Term Loans.

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, 2016, was $24 million for which we have posted collateral of $5 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 

126

its current level, we estimate that additional collateral of $6 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. Revenues and expenses 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. 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 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.

Cash Flow Hedges — We only apply hedge accounting to our interest rate hedging instruments. We report the effective 
portion of the mark-to-market gain or loss on our interest rate hedging instruments 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 interest rate hedging instruments are recognized 
currently in earnings as a component of interest expense. 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 affects 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, interest rate, environmental 
product and fuel oil 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 mark-to-market gain/
loss as a component of operating revenues (for physical and financial power and Heat Rate and commodity option activity) and 
fuel and purchased energy expense (for physical and financial natural gas, power, environmental product and fuel oil activity). 
Changes in fair value of interest rate derivatives not designated as hedging instruments are recognized currently in earnings as 
interest expense.

We elected not to offset fair value amounts recognized as derivative instruments on our Consolidated Balance Sheets 
that are executed with the same counterparty under master netting arrangements or other contractual netting provisions negotiated 
with the counterparty. Our netting arrangements include a right to set off or net together purchases and sales of similar products 
in the margining or settlement process. In some instances, we have also negotiated cross commodity netting rights which allow 
for the net presentation of activity with a given counterparty regardless of product purchased or sold. We also post cash collateral 
in support of our derivative instruments which may also be subject to a master netting arrangement with the same counterparty.

Derivatives Included on Our Consolidated Statements of Operations

Changes in the fair values of our derivative instruments (both assets and liabilities) are reflected either in cash for option 
premiums paid or collected and for the acquisition of derivative instruments in connection with the acquisition of Calpine Solutions, 
in OCI, net of tax, for the effective portion of derivative instruments which qualify for and we have elected cash flow hedge 
accounting treatment, or on our Consolidated Statements of Operations as a component of mark-to-market activity within our 
earnings.

The following tables detail the components of our total activity for both the net realized gain (loss) and the net mark-to-

(1)  We did not record any material gain (loss) on hedge ineffectiveness related to our interest rate hedging instruments designated 

as cash flow hedges during the years ended December 31, 2016, 2015 and 2014.

(2)  We  recorded  income  tax  expense  of  $1  million,  nil  and  nil  for  the  years  ended  December 31,  2016,  2015  and  2014, 

respectively, in AOCI related to our cash flow hedging activities. 

(3)  Cumulative cash flow hedge losses attributable to Calpine, net of tax, remaining in AOCI were $90 million, $127 million
and $149 million at December 31, 2016, 2015 and 2014, respectively. Cumulative cash flow hedge losses attributable to 
the noncontrolling interest, net of tax, remaining in AOCI were $8 million, $11 million and $12 million at December 31, 
2016, 2015 and 2014, respectively.

(4) 

Includes losses of $3 million, nil and $10 million that were reclassified from AOCI to interest expense for the years ended 
December 31, 2016, 2015 and 2014, respectively, where the hedged transactions became probable of not occurring.

We estimate that pre-tax net losses of $40 million would be reclassified from AOCI into interest expense 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.

9. 

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 hedging instruments 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.

131

 
 
 
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

For the years ended December 31, 2016, 2015 and 2014, our income tax rates did not bear a customary relationship to 
statutory  income  tax  rates,  primarily  as  a  result  of  the  effect  of  our  NOLs,  valuation  allowances  and  state  income  taxes. A 
reconciliation of the federal statutory rate of 35% to our effective rate from continuing operations for the years ended December 31, 
2016, 2015 and 2014, is as follows:

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) with a partial offsetting amount recognized in 
OCI. The intraperiod tax allocation included in continuing operations is not material for the years ended December 31, 2016, 2015 
and 2014.

NOL  Carryforwards —  As  of  December 31,  2016,  our  NOL  carryforwards  consisted  primarily  of  federal  NOL 
carryforwards of approximately $6.7 billion, which expire between 2024 and 2033, and NOL carryforwards in 21 states and the 
District of Columbia totaling approximately $3.7 billion, which expire between 2017 and 2036, substantially all of which are 
offset with a full valuation allowance. We also have approximately $647 million in foreign NOLs, which expire between 2025
and 2033, of which a portion is offset with a 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. 

Income Tax Audits — We remain subject to periodic audits and reviews by taxing authorities; however, we do not expect 
these audits 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. Any adjustment of state or federal returns would likely 
result in a reduction of deferred tax assets rather than a cash payment of income taxes in tax jurisdictions where we have NOLs.

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, we are able to consider 
available tax planning strategies.

As of December 31, 2016, we have provided a valuation allowance of approximately $1.6 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 $56 million for the year 
ended December 31, 2016, $199 million for the year ended December 31, 2015 and $410 million for the year ended December 31, 
2014, respectively; all primarily related to income generated in these periods.

In the normal course of business, we evaluate our existing corporate structure and continue to simplify where possible. 
In 2015, we implemented an internal restructuring of certain of our international entities by moving certain foreign subsidiaries 
under a different foreign parent. This restructuring resulted in our ability to further utilize foreign NOLs that were previously 
unavailable to offset the income tax obligation on future earnings and, thus, resulted in a release of approximately $69 million of 
valuation allowance against our NOLs. This reorganization did not have a material effect on our financial condition or cash flows. 

134

Unrecognized Tax Benefits

At December 31, 2016, we had unrecognized tax benefits of $59 million. If recognized, $19 million of our unrecognized 
tax benefits could affect the annual effective tax rate and $40 million, related to deferred tax assets, could be offset against the 
recorded valuation allowance resulting in no effect to our effective tax rate. We had accrued interest and penalties of $12 million
and $12 million for income tax matters at December 31, 2016 and 2015, respectively. We recognize interest and penalties related 
to unrecognized tax benefits in income tax expense (benefit) on our Consolidated Statements of Operations and recorded nil, $1
million and $(2) million for the years ended December 31, 2016, 2015 and 2014, respectively. We believe that it is reasonably 
possible that a decrease within the range of nil and $17 million in unrecognized tax benefits could occur within the next twelve 
months primarily related to foreign tax issues.

A reconciliation of the beginning and ending amounts of our unrecognized tax benefits for the years ended December 31, 

2016, 2015 and 2014, is as follows (in millions):

Balance, beginning of period ...................................................................................... $

11.  Earnings per Share

We 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. Reconciliations of the amounts used in the basic and 
diluted earnings per common share computations for the years ended December 31, 2016, 2015 and 2014, are as follows (shares

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, 
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 awards 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, 2016, there were 
567,000 and 40,533,000 shares of our common stock authorized for issuance to participants under the Director Plan and the Equity 
Plan, respectively. At December 31, 2016, 84,221 shares and 7,214,539 shares remain available for future issuance under the 
Director Plan and the Equity Plan, respectively.

135

Equity Classified Share-Based Awards

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 restricted stock grant with 
annual graded vesting as three separate sub-grants, each representing 33 1/3% of the total number of shares of restricted stock 
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 restricted stock grant with cliff vesting is viewed as one grant vesting over three years.

Stock-based compensation expense recognized for our equity classified share-based awards was $30 million, $31 million
and $31 million for the years ended December 31, 2016, 2015 and 2014, 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, 2016, 2015 and 2014. At December 31, 
2016, there was unrecognized compensation cost of $24 million related to restricted stock which is expected to be recognized over 
a weighted average period of 1.2 years. We issue new shares from our share reserves set aside for the Calpine Equity Incentive 
Plans when stock options are exercised and for other share-based awards.

There were no stock option grants during the years ended December 31, 2016, 2015 and 2014. A summary of all of our 

non-qualified stock option activity for the Calpine Equity Incentive Plans for the year ended December 31, 2016, is as follows:

Liability Classified Share-Based Awards

During the first quarter of 2016, our Board of Directors approved the award of performance share units to certain senior 
management employees. These performance share units will be settled in cash with payouts based on the relative performance of 
Calpine’s TSR over the three-year performance period of January 1, 2016 through December 31, 2018 compared with the TSR 
performance of the S&P 500 companies over the same period, as modified by the IPP Sector Modifier which may either increase 
or decrease the payout based on Calpine’s TSR within its IPP Peers. The performance share units vest on the last day of the 
performance period and will be settled in cash; thus, these awards are liability classified and are measured at fair value using a 
Monte Carlo simulation model at each reporting date until settlement. Stock-based compensation expense recognized related to 
our liability classified share-based awards was $1 million, $(5) million and $5 million for the years ended December 31, 2016, 
2015 and 2014, respectively.

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, $12 million and $12 million for the years ended December 31, 2016, 2015 and 2014, 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.

We also maintain a defined benefit pension plan whereby retirement benefits are primarily a function of age attained, 
years of participation, years of service, vesting and level of compensation. Only approximately 3% of our employees are eligible 
to participate in a defined benefit pension plan. As of December 31, 2016 and 2015, our pension assets, liabilities and related costs 
were not material to us. As of December 31, 2016 and 2015, there were approximately $18 million and $14 million in plan assets 
and  approximately  $26  million  and  $23  million  in  pension  liabilities,  respectively.  Our  net  pension  liability  recorded  on  our 
Consolidated Balance Sheets as of December 31, 2016 and 2015, was approximately $8 million and $9 million, respectively. For 
the years ended December 31, 2016, 2015 and 2014, we recognized net periodic benefit costs of approximately $2 million, $2 
million and $1 million, respectively. Our net periodic benefit cost is included in plant operating expense on our Consolidated 
Statements of Operations. As of December 31, 2016 and 2015, the total amount recognized in AOCI for actuarial losses related 
to pension obligation was approximately $5 million and $5 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 the 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 2016 and 2015, we made contributions of approximately $3 million and $2 million, respectively, and estimated 
contributions to the pension plan are expected to be approximately $2 million in 2016. 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

Our authorized common stock consists of 1.4 billion shares of Calpine Corporation common stock. Common stock issued 
as of December 31, 2016 and 2015, was 359,627,113 shares and 356,755,747 shares, respectively, at a par value of $0.001 per 

137

 
share. Common stock outstanding as of December 31, 2016 and 2015, was 359,061,764 shares and 356,662,004 shares, respectively.

As of December 31, 2016 and 2015, we had treasury stock of 565,349 shares and 93,743 shares, respectively, with a cost 
of $7 million and $1 million, respectively. Our treasury stock consists of shares repurchased as well as our common stock withheld 
to satisfy federal, state and local income tax withholding requirements for vested employee restricted stock awards and net share 
employee stock options exercises under the Equity Plan. All treasury stock is held at cost.

15.  Commitments and Contingencies

Long-Term Service Agreements

As of December 31, 2016, the total estimated commitments for LTSAs associated with turbines were approximately $247 
million. These commitments are payable over the terms of the respective agreements, which range from 1 to 15 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 a long-term operating lease for one of our power plants, extending through 2020, which includes 
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 
lease,  which  may  contain  escalation  clauses  or  step  rent  provisions,  are  recognized  on  a  straight-line  basis.  Certain  capital 
improvements associated with our leased power plant 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 2073. Future minimum rent payments under these 
lease agreements, including renewal options and rent escalation clauses, are as follows (in millions):

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, 2016, 2015 and 2014, were $22 million, 
$23 million and $28 million, respectively.

Office Leases

We  lease  our  corporate  and  regional  offices  under  noncancellable  operating  leases  extending  through  2022.  Future 

minimum lease payments under these leases are as follows (in millions):

costs. During the years ended December 31, 2016, 2015 and 2014, rent expense for noncancelable operating leases was $9 million, 
$11 million and $11 million, respectively.

Commodity Purchases

We enter into commodity purchase contracts of various terms with third parties to supply fuel to our natural gas-fired 
power plants and power to our retail customers. The majority of our purchases are made in the spot market or under index-priced 
contracts. These contracts are accounted for as executory contracts and therefore not recognized as liabilities on our Consolidated 
Balance Sheet. At December 31, 2016, we had future commitments for the purchase, transportation, or storage of commodities as 
detailed below (in millions):

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, retail contracts, contracts associated with the development, construction, operation and maintenance of 
our fleet of power plants and our Accounts Receivable Sales Program. 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.

____________

(1)  Represents Calpine Corporation guarantees of certain power plant capital leases and related interest. All guaranteed capital 

leases are recorded on our Consolidated Balance Sheets.

The standby letters of credit disclosed above represent those disclosed in Note 6.

Letters of credit are renewed annually and as such all amounts are reflected in the year of letter of credit expiration. The 
related commercial obligations extend for multiple years, therefore, renewal of the letter of credit will likely follow the 
term of the associated commercial obligation.

These are contingent off balance sheet obligations.

The majority of surety bonds do not have expiration or cancellation dates.

(2) 

(3) 

(4) 

(5) 

(6)  As of December 31, 2016, no cash collateral is outstanding related to these bonds.

(7)  Calpine has guaranteed the performance of Calpine Solutions under the Accounts Receivable Sales Program. The Accounts 

Receivable Sales Program expires on December 1, 2017.

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 
our partially-owned subsidiaries up to our ownership percentage. The letters of credit issued under various credit facilities support 
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 five 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, environmental products and 
fuel oil to and from third parties with respect to the operation of our power plants and our retail subsidiaries, we may be required 
to guarantee a portion of the obligations of certain of our subsidiaries. We may also be required to guarantee performance obligations 
associated with our marketing, hedging, optimization and trading activities to manage our exposure to changes in prices for energy 
commodities. 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, warranty or 
covenant 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,  maintenance  and  service 
agreements and equipment lease agreements. These guarantee and indemnification obligations may include indemnification from 
personal  injury  or  other  claims  by  our  employees  as  well  as  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 
140

will be resolved. As of December 31, 2016, there are no material 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.

Litigation

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, individually or in the 
aggregate, 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 effect on our financial condition, results 
of operations or cash flows or that would significantly change our operations. 

California Air Resources Board. On November 8, 2016, Russell City Energy Center, LLC received a notice of violation 
for an exceedance of CARB’s annual emission limits for Sulfur Hexafluoride (“SF6”) due to a leak of SF6 experienced for reporting 
year 2015 from one of the high voltage circuit breakers located in the Russell City Energy Center switchyard. SF6 is a gas used 
as an electrical insulator in high voltage circuit breakers and is a GHG. A monetary penalty has not yet been imposed by CARB. 
The liability we may ultimately incur with respect to this matter has not been determined, but it is not expected to be material.

16. 

Segment and Significant Customer Information

We assess our business on a regional basis due to the effect on our financial performance of the differing characteristics 
of these regions, particularly with respect to competition, regulation and other factors affecting supply and demand. At December 31, 
2016, our reportable segments were West (including geothermal), Texas and East (including Canada). The results of our retail 
subsidiaries are reflected in the segment which corresponds with the geographic area in which the retail sales occur. We continue 
to evaluate the optimal manner in which we assess our performance including our segments and future changes may result in 
changes to the composition of our geographic segments.

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).

Significant Customers

For the year ended December 31, 2016, we had no significant customer that individually accounted for more than 10% 
of our annual consolidated revenues. For the year ended December 31, 2015, we had two significant customers, PJM Settlement, 
Inc.  and  PG&E,  that  individually  accounted  for  more  than  10%  of  our  annual  consolidated  revenues.  For  the  year  ended 
December 31, 2014, we had one significant customer, PJM Settlement, Inc. that individually accounted for more than 10% of our 
annual consolidated revenues. Our revenues from PJM Settlement, Inc. for the years ended  December 31, 2015 and 2014 were 
approximately $724 million and $1.0 billion, respectively, and were attributed to our East segment. Our revenues from PG&E for 
the year ended  December 31, 2015 was approximately $642 million, which was attributed to our West segment.

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 and dispositions), 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, optimization and trading 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.

REGULATION G RECONCILIATIONS

ANNEX A

Adjusted EBITDA represents net income attributable to Calpine before net (income) attributable to the noncontrolling interest, 
interest, taxes, depreciation and amortization, adjusted for certain non-cash and non-recurring items as detailed in the following 
reconciliation. Adjusted EBITDA is not intended to represent cash flows from operations or net income as defined by U.S. GAAP 
as an indicator of operating performance and is not necessarily comparable to similarly titled measures reported by other companies.  

We  believe Adjusted  EBITDA  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 mark-
to-market gains or losses from accounting for derivatives, adjustments to exclude the Adjusted EBITDA related to the noncontrolling 
interest, 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, modification or extinguishment of debt, non-cash GAAP-related 
adjustments to levelize revenues from tolling agreements and any unusual or non-recurring items plus 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.  

Adjusted Free Cash Flow represents net income before interest, taxes, depreciation and amortization, as adjusted, less operating 
lease  payments,  major  maintenance  expense  and  maintenance  capital  expenditures,  net  cash  interest,  cash  taxes  and  other 
adjustments, including non-recurring items. Adjusted Free Cash Flow is presented because we believe it is a useful tool for assessing 
the financial performance of our company in the current period. Adjusted Free Cash Flow is a performance measure and is not 
intended to represent net income, the most directly comparable U.S. GAAP measure, or liquidity and is not necessarily comparable 
to similarly titled measures reported by other companies.

Excludes depreciation and amortization expense attributable to the noncontrolling interest.

Adjustments to reflect Adjusted EBITDA from unconsolidated investments include (gain) loss on mark-to-market activity of nil for each of the years 
ended December 31, 2016, 2015 and 2014, respectively.

Includes $257 million, $272 million and $242 million in major maintenance expense for the years ended December 31, 2016, 2015 and 2014, respectively, 
and $148 million, $189 million and $168 million in maintenance capital expenditures for the years ended December 31, 2016, 2015 and 2014, respectively.

Includes commitment, letter of credit and other bank fees from both consolidated and unconsolidated investments, net of capitalized interest and interest 
income.

Adjusted Free Cash Flow, as reported, excludes changes in working capital, such that it is calculated on the same basis as our guidance.

Adjusted EBITDA related to the six power plants sold in our East segment on July 3, 2014, was $43 million for the year ended December 31, 2014.
