to our Shareholders 

MGE Energy is committed to building long-term value 

for our shareholders. To do so, we carefully grow our 

company through strategic investments to meet the 

evolving needs of our customers. 

Our investments have grown the company significantly 

over the last ten years. MGE Energy’s assets more 

than doubled to $1.6 billion. Today, our asset growth 

continues with a multiyear emission-controls project  

at the Columbia Energy Center that will dramatically 

reduce the emissions at this key generation facility. Our  

commitment of $140 million makes this the second 

largest capital expenditure in our company’s history.

Letter
to our Shareholders 

Continuous 
improvement 

At MGE Energy, we are not complacent. 
To enable the next generation to inherit  
a better future, we continually challenge 
ourselves to improve and to innovate.

Environmental  
commitments:  
MGE is the first  
utility in Wisconsin  
to be awarded the 
highest participation 

Advantage: Company Name  Advantage: Environment   

level in Green Tier, the Wisconsin 
Department of Natural Resources’ 
environmental leadership program.

We received the top-level designation 
based on our history of superior  
environmental performance. Under 
Green Tier, we will build on our past 
success with a focus on reducing  
emissions and partnering with others  
on local environmental initiatives. Our 
five-year, voluntary Green Tier agree-
ment underscores our commitment 
to the communities we serve. 

Energy improvements: To ensure a 
cleaner tomorrow, new emission-control 
equipment is under construction at the 
Columbia Energy Center. This equipment 
is projected to reduce both sulfur dioxide 

Electric vehicles provide another  
alternative to gasoline-powered  
vehicles. MGE has just completed a 
network of 26 public charging stations. 
We now are conducting research on how 
our customers who own electric vehicles 
plug in at home and on the road. CNG 
and electricity can help reduce our  
country’s use of foreign oil.

Compressed natural gas (CNG) is a viable option  
for fueling vehicles. MGE’s Dan Clausen and  
Debbie Branson work with our business customers 
interested in CNG. 

MGE’s dedicated 
workforce

In 2012, our workforce was called upon 
to meet some special challenges. During 
one of the hottest summers on record, 
we met our customers’ summer demand 
for power, which peaked just 1% short  
of our all-time record.

and mercury emissions by 90% when 
the controls go online in 2014. MGE  
Energy owns 22% of this coal-fired 
power plant that was built in the 1970s.

We also regularly enhance and improve 
our electric distribution system. In 2012, 
we received a No. 1 electric reliability 
ranking from a nationwide utility industry 
survey based on customer outage times 
in 2011. MGE customers experienced 
the fewest minutes without power,  
only 38 minutes on average per year,  
compared to the nationwide average  
of more than six hours. MGE has ranked 
in the top three utilities in the country for 
reliability in each of the last five years.

Innovations: We embrace the future by 
testing new technologies and developing 
solutions that make sense for today and 
tomorrow. For example, we installed one 
of the first micro-combined heat and 
power (micro-CHP) units in Wisconsin. 
This natural gas-fired unit produces  
heat and electricity simultaneously for 
a building at the Henry Vilas Zoo. The 
micro-CHP is one of more than 30  
technology demonstration projects  
that we have installed. We test the 
performance of these technologies and 
evaluate their potential role in meeting 
our future energy needs.

We also are exploring the roles of natural 
gas and electricity as transportation  
fuels. We are working with businesses 
to promote compressed natural gas 
(CNG) where it is a good fit for their 
transportation needs. With the stability 
of lower natural gas prices and abundant 
supplies, CNG can provide a clean,  
affordable option to gasoline. 

New state-of-the-art emission-control technologies 
are under construction at the Columbia Energy 
Center. The project is scheduled for completion  
in 2014.

Our employees were honored at Wisconsin’s Utility 
Worker Appreciation Day for their role in helping  
restore power and gas service after Hurricane 
Sandy devastated the East Coast. 

In the fall, MGE responded when East 
Coast utilities asked for assistance  
following Hurricane Sandy. MGE sent 
crews to help restore electricity in  
Connecticut and natural gas service  
on Long Island, N.Y. To restore power, 
they cleared trees, battled a snowstorm 
and worked 14-hour days. They slept 
on cots in trailers and came home 
tired. Meanwhile, our crews in Madison 
stepped up to cover their absences.

In December, it was our turn to suffer 
the brunt of nature when a major storm 
dumped 12 to 20 inches of snow with 
winds gusting up to 50 miles per hour.
About 12,000 customers lost power. 
Our employees met the challenge, and 
despite extreme weather conditions, 
power was fully restored within 38 hours. 

At MGE Energy, we take care of  
customer needs today while making 
the improvements needed for tomorrow.  
As a community energy company, we 
are committed to creating a brighter 
future for our next generation.

Wanda Maloney stands on a table in the 
home where Brady Judd grew up with  
his parents Robin and Vint Judd. 

Caring for  
their future

A great-grandparents’ early  
investment yielded lifelong  
returns for one young man.

When Brady Judd was born  
in 1989, shareholders James  
and Wanda Maloney opened  
a custodial MGE Energy stock  
account to help pay college 
tuition for their great-grandson. 
With annual contributions  
and reinvested dividends, the 
investment steadily increased.

James and Wanda, who passed 
away several years ago, weren’t 
there to see Brady graduate  
from the University of Wisconsin-
Madison in 2012. But their legacy 
lives on.

Brady explains, “The MGE  

Energy stock and my great-

grandparents’ encouragement 
set the expectation early  
in my life that I would  

graduate from college. It’s 
a big accomplishment.”

Innovating
to meet future energy needs

Offering new options  
for transportation

As we plan for the future, we believe it is  

important to promote technologies that can 

help lead to a cleaner environment. For that 

reason, we are advancing alternative fuels for 

transportation—compressed natural gas (CNG) 

and electricity. These fuels reduce air emissions,  

decrease our nation’s reliance on foreign oil and  

offer a more affordable option than gasoline. 

Fueling is becoming more convenient with new 

installations of electric vehicle charging stations 

and CNG fueling stations.

Investing in our electric system

To make our electric distribution system “smarter” over time, 
MGE invests in new software and equipment. With our  
improved systems, we can avoid power outages and more 
quickly correct problems for customers. 

A nationwide utility industry survey gave MGE a No. 1 reliability 
ranking. MGE customers experienced the fewest minutes without  
power, only 38 minutes on average per year. MGE’s reliability 
ranked in the top three utilities nationwide in each of the last 
five years. Our innovations today are creating a stronger electric 
system for the future.

Energy alternatives are evidenced in the Hagstrom  
family garage. Jack Hagstrom, 16, fuels their 
Chevy Volt with his father, Jim, who is 
participating in an MGE study that 
evaluates electric vehicle 
charging patterns.

Josh Shepard, an MGE crew leader, works on the distribution 
system near downtown Madison. Upgrades of the electric system 
help maintain high reliability.

“

We need more advancements  

to save resources and hold down  

fuel costs. Electric vehicles are an 

important part of what we need  

6

to do for tomorrow. 

”

Jack Hagstrom, age 16

 
Testing technology helps the zoo

Supporting family farms

MGE moves forward with innovations and tests new technologies 
to understand which technologies will best meet our future 
needs. Since 2000, we have installed more than 30 technology 
demonstration projects throughout our community. 

Most recently, we placed a micro-combined heat and power  
(micro-CHP) unit in the aviary building at the Henry Vilas Zoo 
in Madison. It is one of the first micro-CHPs in Wisconsin. This 
evolving technology uses a natural gas-fired engine to produce 
heat and electricity simultaneously. The unit helps heat the aviary 
while it produces electricity for the grid.

While family farmers harvest their crops, we harvest the wind. 
We pay the farmers an annual fee to use a portion of their land 
to site our wind turbines. This steady source of income can help 
families through the financial ups and downs of farming and can 
help preserve farmland for future generations. 

MGE owns a 17-turbine wind farm in Wisconsin and an  
18-turbine wind farm in Iowa. Partnering with farmers is an 
innovative way to ensure we all benefit from clean energy  
produced here at home.

“MGE is one of our strongest community partners—always  
suggesting new ideas that make the zoo more sustainable,” says 
Ronda Schwetz, director of the Henry Vilas Zoo. 

Kevin LeFevre cuts hay on the Kewaunee County farm that has been 
in his family for generations. LeFevre has leased part of his land to 
MGE since 1999.

Investing
to create a cleaner environment 

Offering green options  
for our energy future 

MGE’s Green Power Tomorrow program gives 

our customers the option to support renewable 

energy from the sun and wind. Nearly 10%  

of our customers buy green power. Many  

of them, like the Statz family of Madison, 

choose to purchase 100% of their energy  

from renewable sources. The Statz children are 

learning firsthand about the energy choices that 

can help create a cleaner tomorrow.

Earning top Green Tier recognition 

MGE is the first utility in Wisconsin to join the Department of 
Natural Resources’ Green Tier program at its highest level. 
This voluntary program recognizes performance that exceeds 
requirements related to health, safety and environment. MGE 
earned this top designation because of our demonstration of  
superior environmental performance. 

As a participant in Green Tier, we will continue our voluntary  
commitment to make significant improvements through  
proactive management strategies and new local partnerships.

The Statz family home is powered by green energy. 
Drew, 14, recognizes that even using the laptop 
has an impact. His father Eric  
and brother Jake discuss a 
future that includes 
renewable energy.

Laura Coleman, an MGE environmental specialist, conducts research 
on Lake Monona. Under Green Tier, MGE has made commitments 
to help improve water quality through local partnerships. 

“

Our future needs to have multiple  

energy options. We need to decrease 

our contributions to greenhouse gases 

while using various types of energy 

sources. 

”

Reducing power plant emissions

Turning biogas into a resource

MGE is investing approximately $140 million in new emission-
control equipment at the Columbia Energy Center. The environ-
mental controls for the coal-fired plant are scheduled to begin 
operation in 2014. They are projected to reduce both sulfur 
dioxide and mercury emissions by 90%. The controls will help 
us deliver a dependable and environmentally responsible power 
supply into the future.

This significant construction project is the second most  
expensive project in our history. MGE owns 22% of this 
1,000-megawatt plant. 

MGE is partnering on a new anaerobic digester to be  
constructed in western Dane County. The digester will  
convert cow manure from several local farms into electricity.  
It is projected to annually produce 11 million kilowatt-hours, 
which can power approximately 1,600 homes.

This manure digester will remove phosphorus that would  
otherwise discharge into our local watershed. Removing  
the phosphorus will result in cleaner lakes and streams.  
Our financial assistance will help protect one of our  
community’s most important assets—our regional watershed.

Randy Pollek, MGE’s joint plant manager, oversees MGE’s interests 
at the Columbia Energy Center in Portage, Wis., where scrubbers, 
baghouses and activated carbon injection systems are being installed. 

Converting cow manure into electricity reduces environmental  
impacts by removing phosphorus from our watershed and by  
reducing greenhouse gas emissions.

Educating
to foster wise energy choices 

Learning by doing  
at the Children’s Museum 

Educating tomorrow’s energy consumers is one 

of our most important responsibilities. MGE  

creates opportunities for energy education  

from libraries to community programs. At the 

Madison Children’s Museum, MGE installed  

a solar demonstration project that allows visitors  

to learn about photovoltaic energy. We want the 

next generation to learn about the renewable 

energy and resources available in our own 

backyards and on our own rooftops.

Becoming more energy efficient 

Businesses large and small are learning about energy efficiency 
and sustainability through the MPower Business ChaMpion 
program. MGE not only provides grants for the program, we  
offer on-site energy evaluations. Participating businesses sign 
up for an intensive yearlong program run by Sustain Dane, a 
local nonprofit organization. 

Through monthly meetings, businesses learn from energy  
experts and from each other to complete improvement  
projects. Flad Architects, one of 50 local businesses to  
participate in the MPower program, pursued energy  
improvements that benefit their business and their clients.

Steve Tone and Laura Schellinger and their 12-year-old 
twins, Sydney and Shelby, learn about energy while  

caring for birds and plants at the Madison  
Children’s Museum rooftop garden, 

where MGE solar panels play a  

role in education. 

Meeting at Flad Architects’ headquarters to discuss energy upgrades 
are (left to right) Jesse Shields of MGE, Annemarie Kalson of Sustain 
Dane, and Garrick Maine and Steve Jackson of Flad. 

“

We learn more when we participate  

and interact. That’s why we volunteer 

in the rooftop garden—there you  

1010

can see the power of solar energy  
everywhere.  

Sydney Tone, age 12

”

Partnering with local schools

Planting ideas for tomorrow 

As a community energy company, MGE is involved with local 
schools. We visit classrooms and teach energy topics to  
approximately 2,000 fourth graders every year. In addition, 
the K-12 Energy Education Program helps teachers learn more 
about energy efficiency and renewable energy—knowledge 
they can incorporate into curriculums.

We have photovoltaic systems on 11 schools in our service 
area. We installed the solar units so students and educators 
can learn more about clean, renewable energy. Energy data 
is provided online at mge.com/solarschools. 

Imagine a building where gardens grow fresh vegetables in the 
soil and photovoltaic installations grow renewable energy on 
the roof. That describes the new Resilience Research Center,  
a community collaboration led by the Center for Resilient Cities. 
This center includes the Badger Rock Middle School, which is 
a new Madison charter school emphasizing sustainability and 
urban agriculture. 

MGE has installed two different solar technologies on the  
building’s rooftop “solar garden.” The students can study the 
performance of the two different solar technologies and can 
compare energy production. 

Jim Reichling, a chemistry and physics teacher at Madison’s  
La Follette High School, is one of the 275 Madison-area teachers 
who participated in the Wisconsin K-12 Energy Education Program. 

Badger Rock Middle School students (left to right) Jason Macera, 
Ryan Felix and Luz Gonzales learn about local sustainability in the 
center’s vegetable garden.

Engaging
to build a healthy and vibrant community

Building for new jobs

The Madison area has a nationally recognized health care 
sector that has grown by 25% over the last decade. We want 
to help ensure this sector continues to grow with new jobs  
and opportunities for the future. 

New medical clinics are rising on the site of a former dairy  
production plant in Madison’s central city. MGE was a key  
player in ensuring this $25 million development project by  
Ghidorzi Companies could take place. We decommissioned  
a small substation adjacent to the site as part of a system  
upgrade. MGE then went to work to install a new transformer 
and distribution service for the 76,800-square-foot building.

Connecting our diverse 
customers to sustainability 

The New Green Challenge is taking energy  

efficiency and sustainability into the homes  

of Madison’s African-Americans and Latinos. 

The six-month challenge encourages customers  

to live more efficiently by saving energy 

and water and by reducing waste. As they  

participate, the families then reach out to  

the community and share their experiences 

online and through radio station broadcasts.

Helping customers save energy

Accelerating high-tech businesses

MGE helps our customers connect to energy efficiency programs 
in our area. Through our assistance, customers can find 
customized energy solutions for their homes and businesses. 
MGE has a history of working with customers to help them make 
smart energy decisions. Since the mid-1980s, our customers 
have saved more than 100 megawatts through conservation. 

The Hinterthuers of Madison made significant improvements to 
their 1920s-era home after an energy audit arranged by MGE. 
They learned the draftiest room in their house had once been a 
sunroom. After ripping down walls, they restored the sunroom 
with new energy-efficient windows.

We work in partnerships to help grow the bioscience and  
tech-based businesses in Madison. 

Two years ago, the University Research Park turned to 
MGE to help design energy-efficient laboratory space in an 
84,000-square-foot facility called the Accelerator. The retrofit 
was completed in 2012. The renovated building now has 85% 
occupancy including two bioscience companies that needed 
space for business expansion. The Research Park also is home 
to the MGE Innovation Center, which has helped grow more 
than 70 early-stage businesses since 1989.

Madison residents Adam, Maggie, Carrie and Brynn Hinterthuer 
enjoy cozy family time in the sunroom area they recently remodeled 
after a home energy audit. 

Bob DiFrancesco checks equipment at Epicentre, located in the 
Accelerator facility. Epicentre is a bioscience company that manufac-
tures innovative kits for life science research.

Filing Format 

This combined Form 10-K is being filed separately by MGE Energy, Inc. (MGE Energy) and Madison Gas and Electric 
Company (MGE). MGE is a wholly owned subsidiary of MGE Energy and represents a majority of its assets, liabilities, 
revenues, expenses, and operations. Thus, all information contained in this report relates to, and is filed by, 
MGE Energy. Information that is specifically identified in this report as relating solely to MGE Energy, such as its 
financial statements and information relating to its nonregulated business, does not relate to, and is not filed by, MGE. 
MGE makes no representation as to that information. The terms "we" and "our," as used in this report, refer to 
MGE Energy and its consolidated subsidiaries, unless otherwise indicated. 

Forward-Looking Statements 

This report, and other documents filed by MGE Energy and MGE with the Securities and Exchange Commission (SEC) 
from time to time, contain forward-looking statements that reflect management's current assumptions and estimates 
regarding future performance and economic conditions—especially as they relate to future load growth, revenues, 
expenses, capital expenditures, financial resources, regulatory matters, and the scope and expense associated with future 
environmental regulation. These forward-looking statements are made pursuant to the provisions of the Private 
Securities Litigation Reform Act of 1995. Words such as "believe," "expect," "anticipate," "estimate," "could," 
"should," "intend," and other similar words generally identify forward-looking statements. Both MGE Energy and MGE 
caution investors that these forward-looking statements are subject to known and unknown risks and uncertainties that 
may cause actual results to differ materially from those projected, expressed, or implied.  

The factors that could cause actual results to differ materially from the forward-looking statements made by a registrant 
include (a) those factors discussed in Item 1A. Risk Factors, Item 7. Management's Discussion and Analysis of 
Financial Condition and Results of Operations, and Item 8. Financial Statements and Supplementary Data, and (b) other 
factors discussed herein and in other filings made by that registrant with the SEC. 

Readers are cautioned not to place undue reliance on these forward-looking statements, which apply only as of the date 
of this report. MGE Energy and MGE undertake no obligation to publicly release any revision to these forward-looking 
statements to reflect events or circumstances after the date of this report. 

Where to Find More Information 

The public may read and copy any reports or other information that MGE Energy and MGE file with the SEC at the 
SEC's public reference room at 100 F Street, NE, Washington, D.C. 20549. The public may obtain information on the 
operation of the Public Reference Room by calling the SEC at 1-800-SEC-0330. These documents also are available to

PART I. 

Item 1. Business. 

MGE Energy operates in the following business segments: 

  Regulated electric utility operations – generating, purchasing, and distributing electricity through MGE. 

  Regulated gas utility operations – purchasing and distributing natural gas through MGE. 

  Nonregulated energy operations – constructing, owning, and leasing electric generating capacity that assists MGE 
through MGE Energy's wholly owned subsidiaries MGE Power Elm Road and MGE Power West Campus. 

  Transmission investments – representing our investment in American Transmission Company LLC, a company 

engaged in the business of providing electric transmission services primarily in Wisconsin. 

  All other – investing in companies and property that relate to the regulated operations and financing the regulated 

operations, through its wholly owned subsidiaries MAGAEL and CWDC, and Corporate functions. 

MGE's utility operations represent a majority of the assets, liabilities, revenues, expenses, and operations of 
MGE Energy. MGE Energy's nonregulated energy operations currently include an undivided interest in two coal-fired 
generating units located in Oak Creek, Wisconsin, which we refer to as the Elm Road Units, and an undivided interest in 
a cogeneration facility located on the Madison campus of the University of Wisconsin, which we refer to as the West 
Campus Cogeneration Facility or WCCF. 

As a public utility, MGE is subject to regulation by the PSCW and the FERC. The PSCW has authority to regulate most 
aspects of MGE's business including rates, accounts, issuance of securities, and plant siting. The PSCW also has 
authority over certain aspects of MGE Energy as a holding company of a public utility. FERC has jurisdiction, under the 
Federal Power Act, over certain accounting practices and certain other aspects of MGE's business.  

MGE Energy's subsidiaries are also subject to regulation under local, state, and federal laws regarding air and water 
quality and solid waste disposal. See "Environmental" below. 

MGE Energy was organized as a Wisconsin corporation in 2001. MGE was organized as a Wisconsin corporation in 
1896. Their principal offices are located at 133 South Blair Street, Madison, Wisconsin 53703, and their telephone 
number is 608-252-7000. 

Electric Utility Operations 

MGE distributes electricity in a service area covering a 316 square-mile area of Dane County, Wisconsin. The service 
area includes the city of Madison, Wisconsin. It owns or leases ownership interests in electric generation facilities 
located in Wisconsin and Iowa. 

At December 31, 2012, MGE supplied electric service to approximately 140,000 customers, with approximately 90% 
located in the cities of Fitchburg, Madison, Middleton, and Monona and 10% in adjacent areas. Of the total number of 
customers, approximately 86% were residential and 14% were commercial or industrial. Electric retail revenues for 
2012, 2011, and 2010 were comprised of the following:

See Item 2. Properties, for a description of MGE's electric utility plant. 

MGE is registered with two regional entities, The Midwest Reliability Organization and Reliability First Corporation. 
The essential purposes of these entities are the development and implementation of regional and NERC reliability 
standards; and determining compliance with those standards, including enforcement mechanisms. 

Transmission 

American Transmission Company LLC (ATC) is owned by the utilities that contributed facilities or capital to it in 
accordance with Wisconsin law. ATC's purpose is to provide reliable, economic transmission service to all customers in 
a fair and equitable manner. ATC plans, constructs, operates, maintains, and expands transmission facilities that it owns 
to provide adequate and reliable transmission of power. ATC is regulated by FERC for all rate terms and conditions of 
service and is a transmission-owning member of the MISO. 

Regional Transmission Organizations 

MISO 
MGE is a nontransmission owning member of the MISO. MISO, a FERC approved RTO, is responsible for monitoring 
the electric transmission system that delivers power from generating plants to wholesale power transmitters. MISO's 
role is to ensure equal access to the transmission system and to maintain or improve electric system reliability in the 
Midwest.  

MISO maintains a bid-based energy market. MGE offers substantially all of its generation on the MISO market and 
purchases much of its load requirement from the MISO market in accordance with the MISO Tariff. MGE participates 
in the ancillary services market (ASM) operated by MISO. The ASM is an extension of the existing energy market in 
which MISO assumes the responsibility of maintaining sufficient generation reserves. In the ASM, MISO provides the 
reserves for MGE's load, and MGE may offer to sell reserves from its generating units.  

MGE participates in the voluntary capacity auction, which provides an optional monthly forum for buyers and sellers of 
aggregate planning resource credits to interact. Load serving entities may participate in the voluntary capacity auction 
potentially to obtain the necessary aggregate planning resource credits needed to meet their planning reserve margin 
requirement. Generator owners may participate to sell any excess aggregate planning resource credits that are not 
needed by them.  

PJM  
MGE is a member of PJM. PJM, an RTO, is a neutral and independent party that coordinates and directs the operation 
of the transmission grid within its area of coverage, administers a competitive wholesale electricity market, and plans 
regional transmission expansion improvements to maintain grid reliability and relieve congestion.  

Fuel supply and generation 

MGE satisfies its customers' electric demand with internal generation and purchased power. During the years ended 
December 31, 2012, 2011, and 2010, MGE's electric energy delivery requirements were satisfied by the following 
sources:

Coal 
MGE and two other utilities jointly own Columbia, a coal-fired generating facility, which accounts for 29% (225 MW) 
of MGE's net summer rated capacity. Power from this facility is shared in proportion to each owner's ownership interest. 
MGE has a 22% ownership interest in Columbia. The other owners are WPL (a subsidiary of Alliant), which operates 
Columbia, and WPSC. The Columbia units burn low-sulfur coal obtained (pursuant to contracts from one to five years 
in length) from the Powder River Basin coal fields located in Wyoming. The coal inventory supply for the Columbia 
units increased from approximately 31 days on December 31, 2011, to approximately 37 days on December 31, 2012. 
The co-owners' current goal is to maintain approximately a 35 day inventory. 

MGE Power Elm Road and two other owners own undivided interests in the coal-fired Elm Road Units in Oak Creek, 
Wisconsin, which accounts for 14% of MGE's net summer rated capacity. Power from this facility is shared in 
proportion to each owner's ownership interest. MGE Power Elm Road owns an 8.33% ownership interest in the Elm 
Road Units and its interest in the Elm Road Units is leased to MGE. The other owners are Wisconsin Energy 
Corporation (which owns approximately 83% of the Elm Road Units and is the operator of those units) and WPPI 
Energy, Inc. The Elm Road Units burn bituminous coal obtained (pursuant to contracts) from northern West Virginia 
and southwestern Pennsylvania. MGE's share of the coal inventory supply for the Elm Road Units increased from 
approximately 36 days on December 31, 2011, to approximately 49 days on December 31, 2012. 

See discussion below under Nonregulated Operations regarding MGE's interest in the Elm Road Units. 

Natural gas and oil 
MGE owns gas-fired combustion turbines. These turbines are primarily located in Madison and Marinette, Wisconsin, 
and have a total of 155 MW of net summer rated capacity. 

MGE also owns the Blount Generating Facility located in Madison, Wisconsin, which is fueled by gas and other 
alternative renewable sources. As planned, capacity was reduced at Blount from 190 MW to 100 MW as of 
December 31, 2011.  

See discussion below under Nonregulated Operations regarding MGE's interest in the West Campus Cogeneration 
Facility. 

Renewable generation sources 
MGE owns 30 MW, consisting of 18 turbines, in a wind-powered electric generating facility in Worth County, Iowa. 
MGE also owns 11 MW, consisting of 17 turbines, in a wind-powered electric generating facility in Kewaunee County, 
Wisconsin.  

Purchased power 
MGE enters into short and long-term purchase power commitments with third parties to meet a portion of its anticipated 
electric energy supply needs. The following table identifies purchase power commitments at December 31, 2012, with 
unaffiliated parties for the next five years.

Gas Utility Operations 

MGE transports and distributes natural gas in a service area covering 1,631 square miles in seven south-central 
Wisconsin counties. The service area includes the city of Madison, Wisconsin and surrounding areas. 

At December 31, 2012, MGE supplied natural gas service to approximately 145,000 customers in the cities of Elroy, 
Fitchburg, Lodi, Madison, Middleton, Monona, Prairie du Chien, Verona, and Viroqua; 24 villages; and all or parts of 
45 townships. Of the total number of customers, approximately 89% were residential and 11% were commercial or 
industrial.

Gas operations accounted for approximately 26.3%, 30.5%, and 31.5% of MGE's total 2012, 2011, and 2010 regulated 
revenues, respectively. 

MGE can curtail gas deliveries to its interruptible customers. Approximately 20% and 14% of retail gas deliveries in 
2012 and 2011, respectively, were to interruptible customers. 

Gas supply 

MGE has physical interconnections with ANR and NNG. MGE's primary service territory, which includes Madison and 
the surrounding area, receives deliveries at one NNG and four ANR gate stations. MGE also receives deliveries at NNG 
gate stations located in Elroy, Prairie du Chien, Viroqua, and Crawford County. Interconnections with two major 
pipelines provide competition in interstate pipeline service and a more reliable and economical gas supply mix, which 
includes gas from Canada and from the mid-continent and Gulf/offshore regions in the United States.  

During the winter months, when customer demand is high, MGE is primarily concerned with meeting its obligation to 
firm customers. MGE meets customer demand by using firm supplies under contracts finalized before the heating 
season, supplies in storage (injected during the summer), and other firm supplies purchased during the winter period. 

By contract, a total of 5,399,949 Dth of gas can be injected into ANR's storage fields in Michigan from April 1 through 
October 31. These gas supplies are then available for withdrawal during the subsequent heating season, November 1 
through March 31. Using storage allows MGE to buy gas supplies during the summer season, when prices are normally 
lower, and withdraw these supplies during the winter season, when prices are typically higher. Storage also gives MGE 
more flexibility in meeting daily load fluctuations. 

MGE's contracts for firm transportation service of gas include winter maximum daily quantities of: 

 
 

162,150 Dth (including 96,078 Dth of storage withdrawals) on ANR. 
60,108 Dth on NNG. 

Nonregulated Energy Operations 

MGE Energy, through its subsidiaries, has developed generation sources that assist MGE in meeting the electricity 
needs of its customers.  

Elm Road 

MGE Power Elm Road and two other owners own undivided interests in the coal-fired Elm Road Units in Oak Creek, 
Wisconsin. Unit 1 entered commercial operation in February 2010, and has the capacity to produce 615 MW of 
electricity. Unit 2 entered commercial operation in January 2011, and has the capacity to produce 615 MW of 
electricity. Wisconsin Energy Corporation owns approximately 83% of the Elm Road Units and is the operator for those 
units. MGE Power Elm Road owns an 8.33% ownership interest in both units. Both units are used to provide electricity 
to MGE's customers. 

MGE leases MGE Power Elm Road's ownership interest in the Elm Road Units pursuant to two separate facility leases. 
The financial terms of each facility lease include a capital structure of 55% equity and 45% long-term debt, return on 
equity of 12.7%, and a lease term of 30 years. At the end of the respective lease terms, MGE may, at its option, renew 
the facility lease for an additional term, purchase the leased ownership interest at fair market value or allow the lease to 
end. The Unit 1 and Unit 2 leases commenced with the commercial operation of each respective unit.

WCCF 

MGE Power West Campus and the UW jointly own undivided interests in a natural gas-fired cogeneration facility on 
the UW campus. The facility has the capacity to produce 20,000 tons of chilled water, 500,000 pounds per hour of 
steam, and approximately 150 MW of electricity. The UW owns 45% of the facility, which represents its interest in the 
chilled-water and steam assets. These assets are used to meet the UW's growing need for air-conditioning and steam-
heat capacity. MGE Power West Campus owns 55% of the facility, which represents its interest in the electric 
generating assets. These assets are used to provide electricity to MGE's customers. The UW's share of the plant and 
portion of the earnings from the WCCF are not reflected in the consolidated financial statements of MGE Energy or 
MGE. MGE Power West Campus' share of the cost of this project is reflected in property, plant, and equipment on 
MGE Energy's and MGE's consolidated balance sheets. 

MGE leases the electric generating assets owned by MGE Power West Campus and is responsible for operating the 
entire facility. The financial terms of the facility lease include a capital structure of 53% equity and 47% long-term debt, 
return on equity of 12.1%, and a lease term of 30 years. At the end of the lease term in 2035, MGE may, at its option, 
renew the facility lease for an additional term, purchase the generating facility at fair market value or allow the lease 
contract to end. 

Transmission Investments 

ATC owns and operates electric transmission facilities primarily in Wisconsin. MGE received an interest in ATC when 
it, like other Wisconsin electric utilities, contributed its electric transmission facilities to ATC. That interest is presently 
held by MGE Transco, which is jointly owned by MGE Energy and MGE. At December 31, 2012, MGE Transco held a 
3.6% ownership interest in ATC. 

In April 2011, ATC and Duke Energy announced the creation of a joint venture, Duke-American Transmission 
Company (DATC), that seeks to build, own, and operate new electric transmission infrastructure in North America to 
address increasing demand for affordable, reliable transmission capacity. 

Environmental 

MGE is subject to frequently changing local, state, and federal regulations concerning air quality, water quality, land 
use, threatened and endangered species, hazardous materials handling, and solid waste disposal. These regulations affect 
the manner in which MGE conducts its operations, the costs of those operations, as well as some capital and operating 
expenditures. They can also affect the siting, timing, and cost of new projects or other significant actions affecting the 
environment. Some of the most significant are addressed below. MGE is not able to predict with certainty the direction 
of future regulations or if compliance with any such regulations will involve additional expenditures for pollution 
control equipment, plant modifications, or curtailment of operations. Such actions could reduce capacity or efficiency at 
existing plants or delay the construction and operation of future generating facilities. MGE management would expect 
to seek and receive rate recovery for costs associated with approval and installation of any required pollution controls. 

Air Quality 

Air quality regulations promulgated by the Environmental Protection Agency (EPA) and Wisconsin Department of 
Natural Resources (WDNR) in accordance with the Federal Clean Air Act and the Clean Air Act Amendments of 1990 
impose restrictions on emission of particulates, sulfur dioxide (SO2), nitrogen oxides (NOx), hazardous air pollutants 
and other pollutants, and require permits for operation of emission sources. These permits must be renewed periodically. 
Various newly enacted and/or proposed federal and state initiatives are expected to result in additional operating and 
capital expenditure costs for fossil-fueled electric generating units.  

Vacation of EPA's Cross State Air Pollution Rule (CSAPR) and Reinstatement of the Clean Air Interstate Rule (CAIR) 
EPA has promulgated three interstate air pollution rules consisting of the NOx SIP Call, the Clean Air Interstate Rule 
(CAIR), and the Cross-State Air Pollution Rule (CSAPR). These rules were each designed to reduce nitrogen oxide 
(NOx) and/or sulfur dioxide (SO2) air emissions from electric generating units (EGUs) located in Wisconsin and other 
states. NOx and SO2 interact in the atmosphere to form ambient ozone and fine particulate matter pollution. As 
explained below, only the CAIR currently affects MGE's generation assets.  

In 2000, the U.S. Court of Appeals for the D.C. Circuit held that Wisconsin had been illegally included in a portion of 
the NOx SIP Call, but stayed the remaining legal challenges to the rule pending EPA's development of additional 
interstate transport rules. At this time, the requirements of the NOx SIP Call and the costs of compliance remain 
uncertain in view of the developments affecting the interstate transport rules. 

11 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In 2005, EPA promulgated the CAIR imposing additional controls on NOx and SO2 emissions from EGUs located in 
Wisconsin and other states. However, in December 2008, the U.S. Court of Appeals for the D.C. Circuit remanded the 
CAIR to the EPA with directions to revise or replace the rule. The Court's remand order directed that the CAIR remain 
in effect until the EPA promulgated a replacement rule. The Court's order did not include a deadline for the EPA to act. 

In August 2011, the EPA responded to the remand of the CAIR by promulgating the CSAPR. However, in August, 
2012, the U.S. Court of Appeals for the D.C. Circuit vacated CSAPR and instructed the EPA to continue administering 
the CAIR pending finalizing a valid alternative program to control interstate pollution. In January 2013, the U.S. Court 
of Appeals for the D.C. Circuit denied EPA's petition for reconsideration decision en banc. At this time, the CAIR 
remains currently effective. 

The CAIR generally requires NOx and SO2 emission reductions from fossil fuel-fired EGUs (25 MW or greater) in the 
eastern half of the United States in two phases and includes a regional cap-and-trade system. The first phase (currently 
in place) requires annual regional emission reductions from 2003 levels of 55% for NOx and 40% for SO2. The second 
phase, scheduled to begin in 2015, reduces regional NOx and SO2 emissions further from 2003 levels to 65% and 70%, 
respectively. MGE owns or has partial ownership in several generation units currently subject to the CAIR: Blount, 
Columbia, Elm Road Units, and its combustion turbines located in West Marinette and Fitchburg.  

Our evaluation of the CAIR demonstrates that MGE is in compliance with the CAIR's Phase I requirements without 
capital expenditures or modifications to our operations. We have also evaluated our potential expenditures if the CAIR 
remains in place for the Phase II reductions. Based on our Phase II evaluation, MGE will be able to meet Phase II NOx 
emissions reductions through using our NOx allowances provided through the rule, and we will meet Phase II SO2 
emissions reductions through installation of pollution controls. New SO2 controls at Columbia are already underway 
and are planned to be completed by early 2014 (see the discussion regarding the Columbia Environmental Project 
below). Once the new environmental control project is completed at Columbia, it is expected that the plant will emit 
SO2 below anticipated Phase II CAIR allocation levels. MGE expects that any costs incurred to meet Phase II of the 
CAIR will be fully recoverable through rates. MGE will continue monitoring the EPA's actions in response to the 
August 2012 CSAPR vacature, and the stayed NOx SIP Call litigation. 

Clean Air Visibility Rule (CAVR) 
Air modeling indicates that SO2 and NOx emissions (and to a lesser extent particulate matter, or PM) from Columbia 
may impair visibility at certain Class I Scenic Areas and may therefore be subject to the best available retrofit 
technology (BART) regulations, a subsection of the EPA's Clean Air Visibility Rule (CAVR), which may require 
pollution retrofits to be installed at Columbia. The EPA had proposed that Columbia's compliance with emissions 
limitations in the CAIR and the CSAPR could also serve as compliance with the BART regulations for SO2 and NOx 
emissions. However, this proposal is now uncertain because of the D.C. Court of Appeals remanding the CAIR to EPA 
and vacating the CSAPR. At this time, the BART regulatory obligations, compliance strategies and costs remain 
uncertain. 

Columbia 

Columbia is a coal-fired generating station operated by WPL in which WPL, WPSC, and MGE have ownership 
interests. In December 2009, the EPA sent a Notice of Violation (NOV) to MGE as one of the co-owners of Columbia. 
The NOV alleges that WPL and the Columbia co-owners failed to comply with appropriate pre-construction review and 
permitting requirements and, as a result, violated the Prevention of Significant Deterioration program requirements, 
Title V Operating Permit requirements of the CAA, and the Wisconsin SIP. In September 2010, the Sierra Club filed a 
civil lawsuit against WPL alleging violations of the CAA at Columbia and other Wisconsin facilities operated by WPL. 
See Footnote 18.e for additional information regarding these matters. MGE believes that the parties have reached a 
tentative agreement on the general terms of a settlement with the EPA and Sierra Club regarding various facilities, 
including Columbia. The parties are currently negotiating a consent decree based upon those general terms, which may 
change during the negotiations.  

Solid Waste 

Proposed Regulation of Coal Combustion Byproducts 
The EPA published a proposed rule on May 4, 2010, to regulate coal combustion byproducts from the electric 
generating sector. If adopted, the final regulations may require new or additional monitoring of storage sites, may re-
classify ash and other coal combustion byproducts, and may regulate ash storage site structural design. MGE is 
evaluating the impact of these proposed regulations on our operations. The EPA has indicated that the final rules will 
likely not be issued until late 2013 or early 2014. It is not possible for MGE to project the potential costs associated 
with the implementation of any of these initiatives until the rule is finalized. 

12 

 
 
 
 
 
 
 
 
 
 
 
 
Global climate change 

MGE is a producer of GHG emissions, primarily from the fossil fuel generating facilities it utilizes to meet customers' 
energy needs, as well as from its natural gas pipeline system and fleet vehicles. Climate change and the regulatory 
response to it could significantly affect our operations in a number of ways, including increased operating costs and 
capital expenditures, restrictions on energy supply options, permitting difficulties, and emission limits. MGE 
management would expect to seek and receive rate recovery of such compliance costs, if and when required. MGE will 
continue to monitor proposed climate change legislation and regulation. 

MGE is already addressing GHG emissions through voluntary actions. In 2005, MGE announced its Energy 2015 Plan, 
which commits to ensuring a balanced, economic energy supply with reduced environmental emissions. The Plan 
emphasizes increased renewable energy, energy efficiency, and new cleaner generation – three strategies that reduce 
GHG emissions. Under MGE's Energy 2015 Plan and other actions, our CO2 emissions are currently projected to 
decline from 2005 to 2015 even though total system energy is estimated to increase.  

Climate Change Legislation 

Federal Actions on Climate Change 
Currently, there is no specific federal proposal for climate change legislation in 2013. Several bills related to GHG 
regulation including bills to limit, prevent or delay the EPA's regulation of GHGs under the current Clean Air Act have 
been proposed previously but none have become law to date. 

State and Regional Actions on Climate Change 
It is not expected that the Wisconsin Legislature will enact broad GHG regulation in 2013. 

DNR's Green Tier Environmental Leadership Program 

MGE is the first utility in Wisconsin to be designated to participate in the highest level (Tier 2) of the DNR's Green Tier 
environmental leadership program. MGE is only the fifth state company to achieve Tier 2 status. Green Tier encourages 
a collaborative approach to environmental performance between the DNR and Wisconsin businesses, local 
governments, and other organizations. As part of Green Tier, participants voluntarily commit to reducing their 
environmental footprint by developing proactive management strategies. These plans act as a roadmap, helping 
organizations see opportunities to adopt new technologies and practices to continually improve their environmental 
performance. 

MGE is participating in the Green Tier program to continue its voluntary commitment to superior environmental 
performance. In cooperation with DNR, MGE will set goals to make significant environmental improvements. 

Employees 

As of December 31, 2012, MGE had 688 employees. MGE employs 210 employees who are covered by a collective 
bargaining agreement with Local Union 2304 of the International Brotherhood of Electrical Workers and 96 employees 
who are covered by a collective bargaining agreement with Local Union No. 39 of the Office and Professional 
Employees International Union. Both of these collective bargaining agreements expire on April 30, 2015. There are also 
5 employees covered by a collective bargaining agreement with Local Union No. 2006, Unit 6 of the United Steel, 
Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial, and Service Workers International Union. This 
collective bargaining agreement expires on October 31, 2015.

Item 1A. Risk Factors. 

MGE Energy and its subsidiaries, including MGE, operate in a market environment that involves significant risks, many 
of which are beyond their control. The following risk factors may adversely affect their results of operations, cash flows 
and market price for their publicly traded securities. While MGE Energy and MGE believe they have identified and 
discussed below the key risk factors affecting their business, there may be additional risks and uncertainties that are not 
presently known or that are not currently believed to be significant that may adversely affect their performance or 
financial condition in the future. 

Regulatory Risk 

We are subject to extensive government regulation in our business, which affects our costs and responsiveness to 
changing events and circumstances. 

Our business is subject to regulation at the State and Federal levels. We are subject to regulation as a holding company 
by the PSCW. MGE is regulated by the PSCW as to its rates, terms and conditions of service; various business practices 
and transactions; financing; and transactions between it and its affiliates, including MGE Energy. MGE is also subject 
to regulation by the FERC, which regulates certain aspects of its business. The regulations adopted by the State and 
Federal agencies affect the manner in which we do business, our ability to undertake specified actions since pre-
approval or authorization may be required, the costs of operations, and the level of rates charged to recover such costs. 
Our ability to attract capital is also dependent in part, upon our ability to obtain a fair return from the PSCW. 

We face risk for the recovery of fuel and purchased power costs.  

MGE burns natural gas in several of its peak electric generation facilities, and in many cases, the cost of purchased 
power is tied to the cost of natural gas. Under the electric fuel rules, MGE would defer electric fuel-related costs that 
fall outside a symmetrical cost tolerance band that is currently plus or minus 2%. Any over/under recovery of the actual 
costs is determined on an annual basis and will be adjusted in future billings to its electric retail customers. Under the 
electric fuel rules, MGE is required to defer the benefit of lower costs if its actual fuel costs fall outside the lower end of 
the range and would defer costs, less any excess revenues, if its actual fuel costs exceeded the upper end of the range. 
Excess revenues are defined as revenues in the year in question that provide MGE with a greater return on common

We are subject to changing environmental laws and regulations that may affect our costs and business plans. 

Our subsidiaries are subject to environmental laws and regulations that affect the manner in which they conduct 
business, including capital expenditures, operating costs and potential liabilities. Changes and developments in these 
laws and regulations may alter or limit our business plans, make them more costly, or expose us to liabilities for past or 
current operations. 

Numerous environmental laws and regulations govern many aspects of our present and future operations, including air 
emissions, water quality, wastewater discharges, solid waste, threatened and endangered species and hazardous waste. 
These evolving regulations can introduce uncertainty with respect to capital expenditures and operational planning, and 
can introduce costly delays if previous decisions need to be revisited as a result of judicial mandate or regulatory 
change. These regulations generally require us to obtain and comply with a wide variety of environmental permits and 
approvals, and can result in increased capital, operating, and other costs and operating restrictions, particularly with 
regard to enforcement efforts focused on obligations under existing regulations with respect to power plant emissions 
and compliance costs associated with regulatory requirements. These effects can be seen not only with respect to new 
construction but could also require the installation of additional control equipment or other compliance measures such 
as altered operating conditions at existing facilities. 

In addition, we may be a responsible party for environmental clean-up at current or future sites identified as containing 
hazardous materials or to which waste was sent that is subsequently determined to be hazardous. It is difficult to predict 
the costs potentially associated with a site clean-up due to the potential joint and several liability for all potentially 
responsible parties, the nature of the clean-up required and the availability of recovery from other potentially 
responsible parties. 

Additionally, depending on their form and phase-in provisions, GHG emission restrictions could have the potential for a 
significant financial impact on MGE, including the cost to install new emission control equipment, purchase 
allowances, or do fuel switching. 

Operating Risk 

We are affected by weather, which affects customer demand and can affect the operation of our facilities. 

The demand for electricity and gas is affected by weather. Very warm and very cold temperatures, especially for 
prolonged periods, can dramatically increase the demand for electricity and gas for cooling and heating, respectively, as 
opposed to the softening effect of more moderate temperatures. Our electric revenues are sensitive to the summer 
cooling season and, to a lesser extent, the winter heating season. Similarly, very cold temperatures can dramatically 
increase the demand for gas for heating. A significant portion of our gas system demand is driven by heating. Extreme 
summer conditions or storms may stress electric transmission and distribution systems, resulting in increased 
maintenance costs and limiting the ability to meet peak customer demand. 

We are affected by economic activity within our service area. 

Higher levels of development and business activity generally increase the numbers of customers and their use of 
electricity and gas. Likewise, periods of recessionary economic conditions generally adversely affect our results of 
operations. 

Our ability to manage our purchased power costs is influenced by a number of uncontrollable factors. 

We are exposed to additional purchased power costs to the extent that our power needs cannot be fully covered by the 
supplies available from our existing facilities and contractual arrangements. Those needs, and our costs, could be 
affected by: 

 

Increased demand due to, for example, weather, customer growth, or customer obligations, 

  The inability to transmit our contracted power from its generation source to our customers due to transmission line 

constraints, outages, or equipment failures, 

  Reductions in the availability of power from our owned or contracted generation sources due to equipment failures, 

shortages of fuel or environmental limitations on operations, and  

15 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Failure to perform on the part of any party from which we purchase capacity or energy, whether due to equipment 
failures or other causes. 

An unexpected change in demand or the availability of generation or transmission facilities can expose us to increased 
costs of sourcing electricity in the short-term market where pricing may be more volatile. 

The equipment and facilities in our operational system are subject to risks which may adversely affect our financial 
performance. 

Weather conditions, accidents, and catastrophic events, including terrorism, cyber terrorism, and acts of sabotage or 
war, can result in damage or failures of equipment or facilities and disrupt or limit our ability to generate, transmit, 
transport, purchase, or distribute electricity and gas. Efforts to repair or replace equipment and facilities may take 
prolonged periods or may be unsuccessful, or we may be unable to make the necessary improvements to our operational 
system, causing service interruptions. The resulting interruption of services would result in lost revenues and additional 
costs. We are also exposed to the risk of accidents or other incidents that could result in damage to or destruction of our 
facilities or damage to persons or property. Such issues could adversely affect revenues or increase costs to repair and 
maintain our systems. 

Failure to attract and retain an appropriately qualified workforce could affect our operations. 

Events such as an aging workforce and retirement of key employees without appropriate replacements may lead to 
operating challenges and increased costs. Some of the challenges include lack of resources, loss of knowledge, and 
length of time period associated with skill development. Failure to identify qualified replacement employees could 
result in decreased productivity and increased safety costs. If we are unable to attract and retain an appropriately 
qualified workforce, our operations could be negatively affected. 

We face construction risk in connection with the completion of the Columbia environmental project.  

The large-scale environmental project at the Columbia generating facility, which is being managed by WPL as plant 
operator, is subject to various risks that could cause costs to increase or delays in completion. These risks include 
shortages of, the inability to obtain, the cost of, and the consistency of, labor, materials and equipment; the inability of 
the general contractor or subcontractors to perform under their contracts; the inability to agree to terms of contracts or 
disputes in contract terms; work stoppages; adverse weather conditions; the inability to obtain necessary permits in a 
timely manner; changes in applicable laws or regulations; adverse interpretation or enforcement of permit conditions; 
governmental actions; legal action; and unforeseen engineering or technology issues. If the construction project is over 
budget, we may not be able to recover those excess costs. Inability to recover excess costs, or inability to complete the 
project in a timely manner, could adversely impact our financial condition and results of operations.  

Financial Risk 

We are exposed to commodity price risk relating to our purchases of natural gas, electricity, coal and oil. 

We face commodity price risk exposure with respect to our purchases of natural gas, electricity, coal and oil, SO2 
allowances and risk through our use of derivatives, such as futures, forwards and swaps, to manage that commodity 
price risk. We could experience increased costs as a result of volatility in the market values of those commodities. We 
could also experience losses on our derivative contracts as a result of that market value volatility or if a counterparty 
fails to perform under a contract. In the absence of actively quoted market prices and pricing information from external 
sources, the valuation of these derivative contracts involves our exercise of judgment and use of estimates. As a result, 
changes in the underlying assumptions or use of alternative valuation methods could affect the reported fair value of 
these contracts.  

We are exposed to interest rate risk.  

We are exposed to interest rate risk on our variable rate financing. Borrowing levels under commercial paper 
arrangements vary from period to period depending upon capital investments and other factors. Such interest rate risk 
means that we are exposed to increased financing costs and associated cash payments as a result of changes in the short-
term interest rates.  

16 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Interest rate movements and market performance affects our employee benefit plan costs. 

Prevailing interest rates affect our assessment and determination of discount rates that are a key assumption in the 
determination of the costs and funding of our defined benefit pension plans and may impact the amount of expense and 
timing of contributions to those plans. The performance of the capital markets affects the values of the assets that are 
held in trust to satisfy the future obligations under our pension and postretirement benefit plans. We have significant 
obligations in these areas and hold significant assets in these trusts. A decline in the market value of those assets may 
increase our current and longer-term funding requirements for these obligations. Changes in the value of trust fund 
assets may affect the level of required contributions to these trusts to meet benefit obligations. Reduced benefit plan 
assets could result in increased benefit costs in future years and may increase the amount and accelerate the timing of 
required future funding contributions.  

We are exposed to credit risk primarily through our regulated energy business. 

Credit risk is the loss that may result from counterparty nonperformance. We face credit risk primarily through MGE's 
regulated energy business. Failure of contractual counterparties to perform their obligations under purchase power 
agreements, commodity supply arrangements or other agreements may result in increased expenses for MGE as a result 
of being forced to cover the shortfall in the spot or short-term market, where prices may be more volatile. 

As a holding company, we are dependent on upstream cash flows from our subsidiaries for the payment of dividends 
on our common stock.  

As a holding company, we have no operations of our own, and our ability to pay dividends on our common stock is 
dependent on the earnings and cash flows of our operating subsidiaries and their ability to pay upstream dividends or to 
repay funds to us. Prior to funding us, our subsidiaries have financial obligations that must be satisfied, including 
among others, debt service and obligations to trade creditors, and are subject to contractual and regulatory restrictions 
on the payment of dividends.  

Disruptions in the financial markets or changes to our credit ratings may affect our ability to finance at a reasonable 
cost and in accordance with our planned schedule. 

The credit markets have experienced disruption and uncertainty in recent years. To the extent that such issues affect the 
ability or willingness of credit providers or investors to participate in the credit markets or particular types of 
investments, or affect their perception of the risk associated with particular types of investments, our cost of borrowing 
could be affected. We also rely on our strong credit ratings to access the credit markets. If our credit ratings are 
downgraded for any reason, borrowing costs could increase, potential investors could decrease, or we could be required 
to provide additional credit assurance, including cash collateral, to contract counterparties. 

General economic conditions may affect our operating revenues, our capital costs and our counterparty risks.  

Operational 
MGE Energy's and MGE's operations are affected by local, national and worldwide economic conditions. The 
consequences of a prolonged period of reduced economic activity may include lower demand for energy, uncertainty 
regarding energy prices and the capital and commodity markets, and increased credit risk. A decline in energy 
consumption may adversely affect our revenues and future growth. Increased credit risk reflects the risk that our retail 
customers will not pay their bills in a timely manner or at all, which may lead to a reduction in liquidity and an eventual 
increase in bad debt expense.  

Liquidity 
Long-term instability in the financial markets, as a result of recession or otherwise, also may affect the cost of capital 
and our ability to raise capital. Although MGE Energy and MGE believe they have sufficient liquidity despite the 
disruption of capital and credit markets, the costs of such funds may increase.  

Counterparty creditworthiness 
Credit risk also includes the risk that trading counterparties that owe us money or product will breach their obligations. 
MGE's risk management policy is to limit transactions to a group of high quality counterparties. Should the 
counterparties to these arrangements fail to perform, we may be forced to enter into alternative arrangements. In that 
event, our financial results could be adversely affected and we could incur losses.

(1)  Net summer rated capacity is determined by annual testing and may vary from year to year due to, among other 

things, the operating and physical conditions of the units. 

(2)  Baseload generation. 

(3)  MGE's 22% share of two 512-MW units. The other owners are WPL (a subsidiary of Alliant), which operates 

Columbia, and WPSC. 

(4)  Facility is jointly owned. MGE Power West Campus owns a controlling interest in the electric generation plant and 
the UW owns a controlling interest in the chilled-water and steam plants. MGE leases the electric generating assets 
owned by MGE Power West Campus and is responsible for operating the facility. Amounts shown represent MGE's 
share of the net summer rated capacity. Based on the terms of the joint plant agreement between MGE and the UW, 
the UW has the ability to reduce net capability of these units by approximately 17 MW in the summer. The net 
summer rated capacity shown reflects this decrease. 

(5)  MGE's 8.33% share in each of two 615 MW coal-fired generating units. The other owners are Wisconsin Energy 

Corporation, which operates the units, and WPPI Energy, Inc. MGE leases the electric generating assets owned by

See discussion below as well as the "Liquidity and Capital Resources - Financing Activities" under Item 7, 
Management's Discussion and Analysis of Financial Condition and Results of Operations, for a description of 
restrictions applicable to dividend payments by MGE. 

Dividend Restrictions 

Dividend payments by MGE to MGE Energy are subject to restrictions arising under a PSCW rate order and, to a lesser 
degree, MGE's first mortgage bonds. The PSCW order limits the amount of dividends that MGE may pay MGE Energy 
when its common equity ratio, calculated in the manner used in the rate proceeding, is less than 55%. Under those 
circumstances, MGE may not pay annual dividends in excess of $39.8 million plus dividends on MGE Energy shares 
issued in excess of the issued share number used in the rate proceeding forecast if the proceeds are invested in MGE. 
MGE's thirteen month rolling average common equity ratio at December 31, 2012, is 58.3%, as determined under the

calculation used in the rate proceeding. MGE paid cash dividends of $20.4 million to MGE Energy in 2012. The rate 
proceeding calculation includes as indebtedness imputed amounts for MGE's outstanding purchase power capacity 
payments and other PSCW adjustments, but does not include the indebtedness associated with MGE Power Elm Road 
and MGE Power West Campus, which are consolidated into MGE's financial statements but are not direct obligations of 
MGE. 

MGE has covenanted with the holders of its first mortgage bonds not to declare or pay any dividend or make any other 
distribution on or purchase any shares of its common stock unless, after giving effect thereto, the aggregate amount of 
all such dividends and distributions and all amounts applied to such purchases, after December 31, 1945, shall not 
exceed the earned surplus (retained earnings) accumulated subsequent to December 31, 1945. As of December 31, 
2012, approximately $281.6 million was available for the payment of dividends under this covenant.

* Under the Stock Plan, common stock shares deliverable to plan participants may be either newly issued shares or 
shares purchased on the open market, as determined from time to time by MGE Energy. In June 2009, 
MGE Energy switched to using open market purchases to provide shares to meet obligations to participants in the 
Stock Plan. The shares are purchased on the open market through a securities broker-dealer and then are reissued 
under the Stock Plan as needed to meet share delivery requirements. The volume and timing of share repurchases 
in the open market depends upon the level of dividend reinvestment and optional share purchases being made from 
time to time by plan participants. As a result, there is no specified maximum number of shares to be repurchased 
and no specified termination date for the repurchases. All shares issued through the Stock Plan, whether newly 
issued or reissued following open market purchases, are issued and sold pursuant to a registration statement that 
was filed with the SEC and is currently effective.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations. 

General 

MGE Energy is an investor-owned public utility holding company operating through subsidiaries in five business 
segments:  

  Regulated electric utility operations, conducted through MGE, 
  Regulated gas utility operations, conducted through MGE, 
  Nonregulated energy operations, conducted through MGE Power and its subsidiaries, 
  Transmission investments, representing our equity investment in ATC, and  
  All other, which includes corporate operations and services.  

Our principal subsidiary is MGE, which generates and distributes electric energy, distributes natural gas, and represents 
a majority portion of our assets, liabilities, revenues, and expenses. MGE generates and distributes electricity to 
approximately 140,000 customers in Dane County, Wisconsin, including the city of Madison, and purchases and 
distributes natural gas to approximately 145,000 customers in the Wisconsin counties of Columbia, Crawford, Dane, 
Iowa, Juneau, Monroe, and Vernon. 

Our nonregulated energy operations own interests in electric generating capacity that is leased to MGE. The 
ownership/leasing structure was adopted under applicable state regulatory guidelines for MGE's participation in these 
generation facilities, consisting principally of a stable return on the equity investment in the new generation facilities 
over the term of the related leases. The nonregulated energy operations include an ownership interest in two coal-fired 
generating units in Oak Creek, Wisconsin and a partial ownership of a cogeneration project on the UW-Madison 
campus. A third party operates the units in Oak Creek, and MGE operates the cogeneration project. Due to the nature of 
MGE's participation in these facilities, the results of our nonregulated operations are also consolidated into MGE's 
consolidated financial position and results of operations under applicable accounting standards. 

Executive Overview 

Our primary focus today and for the foreseeable future is our core utility customers at MGE as well as creating long-
term value for our shareholders. MGE continues to face the challenge of providing its customers with reliable power at 
competitive prices. MGE meets this challenge by investing in more efficient generation projects, including renewable 
energy sources. In the future, MGE will continue to focus on growing earnings while controlling operating and fuel 
costs. MGE will continue to maintain safe and efficient operations in addition to providing customer value. We believe 
it is critical to maintain a strong credit standing consistent with financial strength in MGE as well as the parent company 
in order to accomplish these goals. 

We earn our revenue and generate cash from operations by providing electric and natural gas utility services, including 
electric power generation and electric power and gas distribution. The earnings and cash flows from the utility business 
are sensitive to various external factors, including: 

  Weather, and its impact on customer sales of electricity and gas, 
  Economic conditions, including current business activity and employment and their impact on customer demand, 
  Regulation and regulatory issues, and their impact on the timing and recovery of costs, 
  Energy commodity prices,  
  Equity price risk pertaining to pension related assets, 
  Credit market conditions, including interest rates and our debt credit rating,  
  Environmental laws and regulations, including adopted and pending environmental rule changes, 
  Construction risk in connection with the Columbia environmental project, 

and other factors listed in Item 1A. Risk Factors. 

For the year ended December 31, 2012, MGE Energy's earnings were $64.4 million or $2.79 per share compared to 
$60.9 million or $2.64 per share for the same period in the prior year. MGE's earnings for the year ended December 31, 
2012, were $40.8 million compared to $37.3 million for the same period in the prior year.

Our net income during 2012 compared to 2011 primarily reflects the effects of the following factors: 

  A 4.7% increase in retail electric revenues, driven by increased residential customer demand primarily as a result of 
warmer-than-normal weather. Cooling degree days (a measure for determining the impact of weather during the 
cooling season) increased by 31% compared to the prior period. 

  A 5.5% decrease in gas sales reflecting lower customer demand due to a milder winter. Heating degree days (a 

measure for determining the impact of weather during the heating season) decreased by 15% compared to the prior 
period.  

  MGE has recognized $1.4 million (after tax) in AFUDC equity related to the Columbia environmental project for 

the year ended December 31, 2012. 

Our net income during 2011 compared to 2010 primarily reflects the effects of the following factors: 

  A 3.0% increase in retail electric revenues due to increased customer demand. 

  A 3.0% increase in gas sales reflecting higher customer demand due to a colder winter. Heating degree days 

increased by 3% compared to the prior period.  

  The electric and gas utilities received a one-time $2.6 million (pretax) gain on a sale of property to ATC in 

March 2010.  

  Higher nonregulated energy revenues are attributable to both Elm Road Units being in commercial operation. Elm 
Road Unit 1 was placed in-service in February 2010, and Elm Road Unit 2 was placed in-service in January 2011.  

During 2012, the following events occurred: 

Columbia Environmental Project: In early 2011, the PSCW authorized the construction of air emission reduction 
systems and associated equipment on Columbia Units 1 and 2. MGE's estimated share of the capital expenditures 
required to complete this project is approximately $140 million. MGE expects to incur capital expenditures as follows: 
$68 million in 2013 and $12 million in 2014. As of December 31, 2012, MGE has accumulated $59.9 million 
(excluding carrying costs) related to its share of the project, which is reflected in the Construction Work in Progress 
balance on MGE Energy's and MGE's consolidated balance sheets. Of this amount, MGE has accumulated 
$55.6 million in 2012.  

ATC: MGE Transco contributed $2.1 million for voluntary capital contributions to ATC for the year ended 
December 31, 2012.  

Smart Grid Investment Grant: MGE was approved in 2010 by the U.S. Department of Energy (DOE) under the federal 
stimulus program for a $5.5 million grant for smart grid projects. The DOE grant requires MGE to match the grant 
funding, bringing the total cost of the projects to more than $11 million. The projects involve the installation of 
technologies to boost efficiency, enhance service and improve reliability for customers. The stimulus grant is being used 
to fund the following projects: advanced metering infrastructure, plug-in hybrid electric vehicles support, and 
distribution management. As of December 31, 2012, MGE has spent $8.4 million related to these projects and has 
outstanding agreements to purchase $1.3 million in smart grid related products for 2013.

During 2013, several items may affect us, including: 

2013 Rate Filing: In December 2012, the PSCW authorized MGE to increase 2013 rates for retail electric customers by 
3.8% and to increase rates for gas customers by 1.0%. The change in retail electric rates was driven by costs for new 
environmental equipment at Columbia, final construction costs for the Elm Road Units, transmission reliability 
enhancements, and purchased power costs. 

In December 2012, as part of WEPCO's (the operator and primary owner of the Elm Road Units) 2013 Wisconsin rate 
case, the PSCW determined that 100% of the construction costs for the Elm Road Units were prudently incurred, and 
approved the recovery in rates of more than 99.5% of these costs. In addition, the PSCW deferred the final decision 
regarding the $1.8 million fuel flexibility project (MGE Power Elm Road's share) until a future rate proceeding. 

Environmental Initiatives: There are proposed legislation, rules and initiatives involving matters related to air emissions, 
water effluent, hazardous materials and greenhouse gases, all of which affect generation plant capital expenditures and 
operating costs as well as future operational planning. Such legislation and rulemaking could significantly affect in 
particular the costs of owning and operating fossil-fueled generating plants, such as Columbia and the Elm Road Units, 
from which we derive approximately 43% of our electric generating capacity. We would expect to seek and receive 
recovery of any such costs in rates; however, it is difficult to estimate the amount of such costs due to the uncertainty as 
to the timing and form of the legislation and rules, and the scope and time of the recovery of costs in rates. In addition, 
MGE is involved in claims surrounding the alleged failure, among other things, to obtain necessary air permits and 
implement necessary emission controls associated with past activities at Columbia. MGE and the other co-owners are 
defending against these claims. See Columbia discussion in Footnote 18.e in Notes to Consolidated Financial 
Statements. 

Columbia Environmental Project: During 2013, our share of the capital expenditures associated with the Columbia 
environmental project will be approximately $68 million. We intend to fund any remaining capital commitments with 
funds generated from normal operations, and the issuance of long-term and short-term debt. 

General economic conditions: Economic conditions both inside and outside our service area are expected to continue to 
affect the level of demand for our utility services and may affect the collection of our accounts receivable and the 
creditworthiness of counterparties with whom we do business. We have in place lines of credit aggregating 
$115.0 million for MGE Energy (including MGE) and $75.0 million for MGE to address our liquidity needs. 

The following discussion is based on the business segments as discussed in Footnote 23.

Electric operating revenues increased $16.5 million or 4.4% for the year ended December 31, 2012, due to the 
following:

(0.8) 
(0.7) 
16.5  

  Rates changes. Rate changes have resulted in $19.0 million of additional revenue in 2012 compared to the same 

period in the prior year. The change is primarily a result of an electric retail rate increase which was authorized by 
the PSCW. Effective January 1, 2012, the retail rate increased 4.3% or $15.7 million for electric retail customers. 
The increase in electric rates was driven by MGE's electric fuel and purchased power costs, increased transmission 
costs, an update to the Elm Road Units' costs, and an increase for energy efficiency programs. Other factors also 
contributed to the revenue increase over the prior year, including customer mix (sales to various customer classes), 
demand charges, and customer fixed charges.  

  Volume. During the year ended December 31, 2012, there was a 0.3% decrease in total retail sales volumes 

compared to the same period in the prior year, reflecting decreased industrial customer demand, offset in part by an 
increase in residential demand. 

  Adjustments to revenues. The adjustments to revenues amount includes the elimination of carrying costs for Elm 

Road Units and WCCF that were collected in electric rates, which are recognized as nonregulated energy operating 
revenues in our Nonregulated Energy Operations segment.  

 

Sales to the market. Sales to the market represent wholesale sales made to third parties who are not ultimate users 
of the electricity. These sales may include spot market transactions on the markets operated by MISO and PJM. 
These sales may also include bilateral sales to other utilities or power marketers.  

Electric fuel and purchased power 

The expense for fuel for electric generation decreased $4.3 million or 8.5% during the year ended December 31, 2012, 
compared to the same period in the prior year. Internal electric generation costs decreased $3.2 million as a result of a 
6.3% decrease in the per-unit cost (largely due to lower natural gas prices), and lower generation volumes of 1.1% or 
$1.1 million. 

Excluding the fuel rules adjustments discussed below, purchased power expense increased $3.6 million during the year 
ended December 31, 2012, compared to the same period in the prior year. This increase in expense reflects a 
$3.0 million or 4.7% increase in per-unit cost of purchased power and a $0.6 million or 0.9% increase in the volume of 
power purchased from third parties.  

The PSCW adopted new fuel rules effective January 1, 2011, that require MGE to defer electric fuel-related costs that 
fall outside a 2% cost tolerance band around the amount used in the most recent rate proceeding. Any fuel rules 
adjustments are reflected in purchased power expense. During the year ended December 31, 2012, MGE's actual fuel 
costs fell below the lower end of this tolerance band, which resulted in MGE deferring $6.2 million in fuel-related cost 
savings to be returned to customers and increased purchased power costs. Any over/under recovery of the deferred costs 
is determined on an annual basis and adjusted in future billings to customers. After combining the fuel rules adjustments 
with the actual savings discussed above, purchased power expense increased $9.8 million ($6.2 million fuel rules 
difference plus the $3.6 million purchased power expense increase discussed above) during the year ended 
December 31, 2012, compared to the prior year.

Electric operating and maintenance expenses 

Electric operating and maintenance expenses increased $4.7 million during the year ended December 31, 2012, 
compared to the same period in 2011. The following changes contributed to the net change: 

(In millions) 
Increased administrative and general costs ....................... $

0.9  
0.6  
0.2  
(1.7) 
4.7  

For the year ended December 31, 2012, increased administrative and general costs are primarily due to increased 
pension costs, reflecting changes in the discount rate and assumptions regarding investment returns used in calculating 
such costs. Increased customer service costs are due to higher energy conservation spending. Increased transmission 
costs are due to higher transmission network costs. Production costs decreased primarily due to decreased costs at 
Columbia and Blount. 

Electric depreciation expense 

Electric depreciation expense decreased $2.3 million for the year ended December 31, 2012, compared to the same 
period in the prior year. This decrease is related to the retirement of Blount assets at the end of 2011 due to the switch 
from operating with coal to natural gas.

  Rates changes. Rates charged to retail customers for the year ended December 31, 2011, were 2.2% or $8.2 million 

higher than those charged during the same period in the prior year. 

In January 2011, the PSCW authorized MGE to increase 2011 rates for retail electric customers by 2.3% or 
$8.0 million. The increase in retail electric rates is driven by costs for MGE's share of the Elm Road Units.  

  Adjustments to revenues. The adjustments to revenues amount includes the elimination of carrying costs for Elm 

Road Units and WCCF that were collected in electric rates, which are recognized as nonregulated energy operating 
revenues in our Nonregulated Energy Operations segment. The amount eliminated was $6.0 million and 
$7.0 million for the years ended December 31, 2011 and 2010, respectively. 

During the year ended December 31, 2010, MGE recovered in electric rates the costs associated with the estimated 
commencement of lease payments for Elm Road Unit 2, which did not commence until the commercial operation 
of the Unit in 2011. These amounts were deferred on MGE's balance sheet. At December 31, 2010, $3.6 million 
was included in adjustments to revenues to defer these revenues and will be returned to customers in MGE's next 
base rate case. 

  Volume. During the year ended December 31, 2011, there was a 0.8% increase in total retail sales volumes 

compared to the same period in the prior year, reflecting increased commercial customer demand. 

 

Sales to the market. Sales to the market represent wholesale sales made to third parties who are not ultimate users 
of the electricity. These sales may include spot market transactions on the markets operated by MISO or PJM. 
These sales may also include bilateral sales to other utilities or power marketers. Generating units are dispatched by 
MISO based on cost considerations as well as reliability of the system. Sales to the market typically occur when 
MGE has more generation and purchases online than is needed for its own system demand. The excess electricity is 
then sold to others in the market. For the year ended December 31, 2011, market volumes increased compared to 
the prior year, reflecting increased opportunities for sales, however, market settlement resulted in lower revenue 
per kWh for the year ended December 31, 2011, reflecting lower market prices. Also included in the sales to the 
market is a decrease in revenues pertaining to the ancillary services and capacity markets, which have no 
corresponding market volumes. 

  Other Revenues. Other revenues decreased a total of $0.3 million compared to the same period in the prior year. 

Electric fuel and purchased power 

The expense for fuel for electric generation increased $8.9 million or 21.2% during the year ended December 31, 2011, 
compared to the same period in the prior year, reflecting higher generation at the Elm Road Units. Elm Road Unit 1 and 
Unit 2 entered commercial operation in February 2010 and January 2011, respectively. 

Purchased power expense decreased by $7.2 million or 10.0% during the year ended December 31, 2011, compared to 
the same period in the prior year. This decrease in expense reflects a $7.8 million or 10.9% decrease in the volume of 
power purchased from third parties, driven by Elm Road Unit 2 becoming operational in January 2011.  

Electric operating and maintenance expenses 

Electric operating and maintenance expenses increased $0.6 million during the year ended December 31, 2011, 
compared to the same period in 2010. The following changes contributed to the net change: 

(In millions) 
Increased production costs ................................................ $
Increased distribution costs ...............................................
Decreased transmission costs ............................................
Decreased customer service costs .....................................
Total .................................................................................. $

0.7

For the year ended December 31, 2011, increased production costs largely reflect increased maintenance at the Blount 
plant and increased production at the Elm Road Units. Increased distribution costs are primarily due to increased tree 
trimming expenses. These increases were partially offset by decreased transmission costs, primarily due to a decrease in 
network service fees pertaining to ATC.

the prior year. This increase is related to higher levels of gas assets. 

Other Income (Deductions), Net - MGE Energy and MGE 

For the year ended December 31, 2011, other income, net for the electric and gas segments decreased by $2.9 million, 
compared to the same period in the prior year. This decrease is primarily due to a one-time $2.6 million pretax gain on a 
sale of property to ATC during March 2010. 

Nonregulated Energy Operations - MGE Energy and MGE 

Nonregulated energy operating revenues 

Operating revenues from nonregulated energy operations increased $9.0 million for the year ended December 31, 2011, 
when compared to the same period in the prior year, reflecting the commencement of commercial operations at Elm 
Road Unit 2 in January 2011.  

MGE received approval from the PSCW to collect from customers the carrying costs incurred by MGE Power Elm 
Road during construction of the Elm Road Units. The total carrying costs on the Elm Road Units is $62.2 million. A 
portion of this amount is being recognized over the period in which Elm Road Units costs are recovered in rates and a 
portion is being deferred and will be recognized over the period in which the Units are depreciated. See Footnote 2 for 
additional information regarding these carrying charges. For the years ended December 31, 2011 and 2010, MGE Power 
Elm Road recognized $3.9 million and $4.8 million, respectively, related to carrying costs on the Elm Road Units.  

Nonregulated depreciation expense 

Nonregulated depreciation expense increased $1.8 million for the year ended December 31, 2011, compared to the same 
period in the prior year. This additional depreciation is related to the commencement of commercial operations at Elm 
Road Unit 2 in January 2011. 

Nonregulated energy interest expense, net 

For the years ended December 31, 2011 and 2010, interest expense, net at the nonregulated energy operations segment 
was $6.3 million and $2.7 million, respectively. Interest expense at the nonregulated energy segment for both the years 
ended December 31, 2011 and 2010, includes interest expense incurred on $50 million of borrowings at MGE Power 
West Campus, and $50 million of borrowings at MGE Power Elm Road, which were long-term and fixed-rate during 
both periods. Interest expense at the nonregulated energy segment for the year ended December 31, 2011, also includes 
interest incurred on $30 million of additional borrowings at MGE Power Elm Road, which were issued in late 
February 2011, and were long-term and fixed-rate during 2011. 

Transmission Investment Operations - MGE Energy and MGE

Consolidated Income Taxes - MGE Energy and MGE 

MGE Energy's effective income tax rate for the year ended December 31, 2011, was 37.1% compared to 37.0% for the 
same period in 2010, and MGE's effective income tax rate for the years ended December 31, 2011 and 2010, was 
37.0%. 

For 2009 tax return purposes, MGE Energy and MGE changed their income tax method of accounting for electric 
repairs. The effect on the 2010 financial statements of the finalization pertaining to the electric repairs adjustment is an 
increase to deferred tax expense and a corresponding decrease in the current tax provision in the amount of 
approximately $6.0 million. 

The tax method change did not have an impact on income before income tax expense in the income statements of 
MGE Energy and MGE. 

Noncontrolling Interest, Net of Tax - MGE 

The noncontrolling interest, net of tax, reflects the accounting required for MGE Energy's interest in MGE Power Elm 
Road (the Elm Road Units) and MGE Power West Campus (WCCF). MGE Energy owns 100% of MGE Power Elm 
Road and MGE Power West Campus; however, due to the contractual agreements for these projects with MGE, the 
entities are considered VIEs and their results are consolidated with those of MGE, the primary beneficiary of the VIEs.

The cash flows for the year ended December 31, 2012, reflect an $11.1 million benefit of lower taxes payable, 
compared to the same period in the prior year, primarily due to the additional benefit from the income tax method 
change in accounting for repairs and bonus depreciation.  

Working capital accounts resulted in $0.3 million in cash used for operating activities for the year ended December 31, 
2012, primarily due increased accounts receivable and increased unbilled revenues, partially offset by a decreased 
receivable – margin account and decreased prepaid taxes. Working capital accounts resulted in $7.0 million in cash 
provided by operating activities for the year ended December 31, 2011, primarily due to decreased inventories (due to 
lower natural gas costs), decreased unbilled revenues and increased accounts payable, partially offset by an increased 
receivable – margin account. 

An increase in pension contribution resulted in an additional $5.2 million in cash used for operating activities for the 
year ended December 31, 2012, when compared to the same period in the prior year. These contributions reflect 
amounts required by law and discretionary amounts. See Footnote 13 for further discussion of MGE Energy's pension 
and other postretirement benefits. 

MGE Energy's other noncurrent items, net resulted in $7.0 million of operating cash inflows for the year ended 
December 31, 2012, compared to $3.9 million of operating cash outflows in the prior year. This increase in cash inflows 
is a result of fuel related cost savings to be returned to customers.  

2011 vs. 2010 

Cash provided by operating activities for the year ended December 31, 2011, was $130.8 million, an increase of 
$6.7 million when compared to the same period in the prior year, primarily due to working capital changes and the 
benefit of less taxes paid as a result of a tax method change in accounting for repairs and bonus depreciation that was 
available in 2011 for capital improvements placed in service during that year. 

MGE Energy's net income increased $3.2 million for the year ended December 31, 2011, when compared to the same

resulted in $3.8 million in cash used by operating activities for the year ended December 31, 2010, primarily due to 
increased receivables and decreased payables, partially offset by decreased prepaid taxes (a result of a tax method 
change in accounting for repairs) and decreased inventories. 

An increase in pension contribution resulted in an additional $6.8 million in cash used for operating activities for the 
year ended December 31, 2011, when compared to the same period in the prior year. These contributions reflect 
amounts required by law and discretionary amounts. See Footnote 13 for further discussion of MGE Energy's pension 
and other postretirement benefits. 

MGE Energy's other noncurrent items, net resulted in $3.9 million of operating cash outflows for the year ended 
December 31, 2011, compared to $8.9 million of operating cash inflows in the prior year. This decrease in cash inflows 
is a result of the regulatory liability for Elm Road Units related costs. In 2010, MGE started collecting lease payments 
based on the expected commercial operation dates of the Elm Road Units. The difference between the expected start 
date and the actual start date of the lease payments on those Units will be returned to customers in the next base rate 
case.

Capital expenditures for the year ended December 31, 2012, were $98.4 million. This amount represents a $33.3 million 
increase from the expenditures made in the same period in the prior year. This increase is due to increased expenditures 
on the Columbia environmental project of $43.0 million offset by a decrease in electric utility capital expenditures in 
2012.  

Cash used for investment activities increased $1.4 million for the year ended December 31, 2012, when compared to the 
same period in the prior year as a result of increased capital contributions to ATC and other investments.

In early 2011, the PSCW authorized the construction of air emission reduction systems and associated equipment on 
Columbia Units 1 and 2. MGE's estimated share of the capital expenditures required to complete this project is 
approximately $140 million. MGE expects to incur capital expenditures as follows: $68 million in 2013 and $12 million 
in 2014. MGE Energy intends to fund any remaining capital commitments for Columbia with funds generated from 
normal operations, and the issuance of long-term and short-term debt. As of December 31, 2012, MGE had incurred 
$51.6 million (excluding carrying costs) in construction expenditures at Columbia related to the project and had accrued 
$8.3 million in incurred, but unpaid capital expenditures. MGE has recognized $1.4 million (after tax) in AFUDC equity 
related to this project for the year ended December 31, 2012. 

MGE Energy used funds received as dividend payments from MGE Power West Campus and MGE Power Elm Road as 
well as internally generated cash to meet its 2012 capital requirements and cash obligations, including dividend 
payments.

Dividend Restrictions 

Dividend payments by MGE to MGE Energy are subject to restrictions arising under a PSCW rate order and, to a lesser 
degree, MGE's first mortgage bonds. The PSCW order limits the amount of dividends that MGE may pay MGE Energy 
when its common equity ratio, calculated in the manner used in the rate proceeding, is less than 55%. Under those 
circumstances, MGE may not pay dividends in excess of $39.8 million for both 2012 and 2011, plus dividends on 
MGE Energy shares issued in excess of the shares issued in the rate proceeding forecast if the proceeds are invested in 
MGE. MGE's thirteen month rolling average common equity ratio at December 31, 2012 and 2011, is 58.3% and 
57.3%, respectively, as determined under the calculation used in the rate proceeding. MGE was not restricted from 
paying cash dividends in 2012. Cash dividends of $20.4 million and $26.6 million were paid by MGE to MGE Energy 
in 2012 and 2011, respectively. The rate proceeding calculation includes as indebtedness imputed amounts for MGE's 
outstanding purchase power capacity payments and other PSCW adjustments, but does not include the indebtedness 
associated with MGE Power Elm Road and MGE Power West Campus, which are consolidated into MGE's financial 
statements but are not direct obligations of MGE.

MGE has covenanted with the holders of its first mortgage bonds not to declare or pay any dividend or make any other 
distribution on or purchase any shares of its common stock unless, after giving effect thereto, the aggregate amount of 
all such dividends and distributions and all amounts applied to such purchases, after December 31, 1945, shall not 
exceed the earned surplus (retained earnings) accumulated subsequent to December 31, 1945. As of December 31, 
2012, approximately $281.6 million was available for the payment of dividends under this covenant. 

Credit Facilities 

At December 31, 2012, MGE Energy and MGE had the following aggregate bank commitments and available capacity

July 31, 2015 

Borrowings under each credit agreement may bear interest at a rate that floats daily based upon a prime rate or at a rate 
fixed for a specified interest period based upon a LIBOR-based index, plus an adder. In the case of the LIBOR-based 
rates, the adder is based upon the senior unsecured credit rating for MGE and does not exceed 0.85%.  

The agreements require the borrower to maintain a ratio of consolidated debt to consolidated total capitalization not to 
exceed a maximum of 65%. The ratio calculation excludes assets, liabilities, revenues, and expenses included in MGE's 
financial statements as a result of the consolidation of VIEs, such as MGE Power Elm Road and MGE Power West 
Campus. At December 31, 2012, the ratio of consolidated debt to consolidated total capitalization for each of 
MGE Energy and MGE, as calculated under the credit agreements' covenant, were 38.4% and 35.5%, respectively. See 
Footnote 10, for additional information regarding the credit facilities. 

Capitalization Ratios 

MGE Energy's capitalization ratios were as follows: 

Common shareholders' equity ................
Long-term debt* ....................................

MGE Energy  

2012   
61.6 % 
38.4 % 

2011   
60.2 % 
39.8 % 

*Includes the current portion of long-term debt. 

Credit Ratings 

MGE Energy's and MGE's access to the capital markets, including, in the case of MGE, the commercial paper market, 
and their respective financing costs in those markets, may depend on the credit ratings of the entity that is accessing the 
capital markets.  

None of MGE Energy's or MGE's borrowing is subject to default or prepayment as a result of a downgrading of credit 
ratings, although a downgrading of MGE's credit ratings could increase fees and interest charges under both 
MGE Energy's and MGE's credit agreements.

(a)  Long-term debt consisting of secured first mortgage bonds, unsecured medium-term notes, Industrial Development 
Revenue Bonds issued by MGE, and private placement debt issued by MGE, MGE Power Elm Road and MGE 
Power West Campus.  

(b)  No short-term debt outstanding. See Footnote 10 of the Notes to Consolidated Financial Statements.  

(c)  Amount represents interest expense on long-term facilities. See Footnote 9 of the Notes to Consolidated Financial 

Statements for further discussion of the long-term debt outstanding at December 31, 2012. 

(d)  Operating leases. See Footnote 18 of the Notes to Consolidated Financial Statements. 

(e)  Purchase obligations for MGE Energy and MGE consist primarily of the purchase of electricity and natural gas, 
electric transmission, natural gas storage capacity, natural gas pipeline transportation, and the purchase and 
transport of coal. See Footnote 18 of the Notes to Consolidated Financial Statements. 

(f)  Other obligations are primarily related to investment commitments, easements, maintenance and service 

agreements, smart grid projects, green energy projects, water quality environmental projects, fuel credit, and 
uncertain tax positions. 

(g)  Purchase obligations for MGE Energy and MGE related to contracts for equipment and services related to the 
construction of the Columbia environmental project. See Footnote 18 of the Notes to Consolidated Financial 
Statements. 

The above amounts do not include any contributions for MGE's pension and postretirement plans. Contributions to the 
plans for 2013 are expected to be approximately $32 million, of which $30 million was paid in January 2013. For 2014 
and 2015, contributions are expected to be between $11 million to $13 million each year. The contributions for years 
after 2015 are not yet currently estimated. MGE has adopted the asset smoothing as permitted in accordance with the 
Pension Protection Act of 2006, including modifications made by WRERA. Due to uncertainties in the future economic 
performance of plan assets, discount rates, and other key assumptions, estimated contributions are subject to change. 
MGE may also elect to make additional discretionary contributions. 

The above amounts do not include future voluntary capital calls to ATC. On January 31, 2013, MGE Transco made a 
voluntary $0.2 million capital contribution to ATC. The amount and timing of future voluntary capital calls is uncertain 
and primarily dependent on the operations and expansion of ATC.

used to support commercial paper issuances. At December 31, 2012, there were no borrowings under this facility. 

Other Matters 

Elm Road 

In December 2012, as part of WEPCO's (the operator and primary owner of the Elm Road Units) 2013 Wisconsin rate 
case, the PSCW determined that 100% of the construction costs for the Elm Road Units were prudently incurred, and 
approved the recovery in rates of more than 99.5% of these costs. In addition, the PSCW deferred the final decision 
regarding the $1.8 million fuel flexibility project (MGE Power Elm Road's share) until a future rate proceeding. 

The warranty periods for both of the Elm Road Units have expired. WEPCO and Bechtel (the construction contractor 
for the Elm Road Units) are working through outstanding warranty claims. According to WEPCO, the warranty claim 
for the costs incurred to repair steam turbine corrosion damage identified on both units will be resolved through a 
binding arbitration hearing scheduled for October 2013. In accordance with the contract with Bechtel, final acceptance 
of the units cannot occur until, among other things, all disputes have been settled. 

ATC 

In April 2011, ATC and Duke Energy announced the creation of a joint venture, Duke-American Transmission 
Company (DATC), that seeks to build, own and operate new electric transmission infrastructure in North America to 
address increasing demand for affordable, reliable transmission capacity. DATC has announced various transmission 
projects to be constructed over the next 10 years. These projects are subject to approval by various regulatory agencies. 
At December 31, 2012, MGE Transco held a 3.6% ownership interest in ATC. Additional capital contributions by MGE 
Transco to ATC may be required. 

PJM Resettlement 

MGE is a member of PJM. PJM, an RTO, is a neutral and independent party that coordinates and directs the operation 
of the transmission grid within its area of coverage, administers a competitive wholesale electricity market, and plans 
regional transmission expansion improvements to maintain grid reliability and relieve congestion. In 2009, PJM 
determined certain market participants, including MGE, were not eligible to receive transmission loss credits. In 
September 2009, MGE paid PJM $1.2 million at that time as part of this resettlement. 

In July 2011, FERC reversed the 2009 decision and determined PJM should refund certain amounts back to market 
participants, including MGE. In May 2012, FERC denied rehearing requests by financial marketers and ordered the 
resettlement. In July 2012, MGE received a $1.2 million refund from PJM related to the resettlement, which was 
credited to purchased power.

that MGE would have to pay back the refund received from PJM. 

Critical Accounting Estimates - MGE Energy and MGE 

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 
of America requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, 
revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our 
estimates, including those related to unbilled revenues, allowance for doubtful accounts, pension obligations, income 
taxes, derivatives, and regulatory assets and liabilities. We base our estimates on historical experience and on various 
assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making 
judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Those 
values may differ from these estimates under different assumptions or conditions. We believe the following critical 
accounting estimates affect our more significant judgments used in the preparation of our consolidated financial 
statements. 

Unbilled Revenues 

Revenues from the sale of electricity and gas to customers are recorded when electricity/gas is delivered to those 
customers. The quantity of those sales is measured by customers' meters. Due to the large volume of those meters, it is 
impractical to read all of them at month end. Meters are read on a systematic basis throughout the month based on 
established meter-reading schedules. Consequently, at the end of any month, there exists a quantity of electricity and 
gas that has been delivered to customers but has not been captured by the meter readings. As a result, management must 
estimate revenue related to electricity and gas delivered to customers between their meter-read dates and the end of the 
period. These estimates include: 

  The amount of electricity expected to be lost in the process of its transmission and distribution to customers (line 

loss) and the amount of electricity actually delivered to customers. 

  The amount of gas expected to be lost in the process of its distribution to customers and the amount of gas actually 

delivered to customers. 

  The mix of sales between customer rate classes, which is based upon historical utilization assumptions. 

MGE monitors the reasonableness of the unbilled revenue estimate through the review of ratios such as unbilled electric 
consumption compared to billed electric sales. In the case of unbilled gas, the estimated unbilled consumption is 
compared to various other statistics, including percent of gas available for sale, change in unbilled month to month and 
change in unbilled compared to the prior year in order to confirm its reasonableness. 

Allowance for Doubtful Accounts 

MGE maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to 
make required payments. It determines the allowance based on historical write-off experience, regional economic data, 
and review of the accounts receivable aging. MGE reviews its allowance for doubtful accounts monthly. Although 
management believes that the allowance for doubtful accounts is MGE's best estimate of the amount of probable credit 
losses, if the financial condition of MGE's customers were to deteriorate, resulting in an impairment of their ability to 
make payments, additional allowances may be required.  

Pension and Other Postretirement Benefit Plans 

MGE provides employees with certain retirement (pension) and postretirement (health care and life insurance) benefits. 
In order to measure the expense and obligations associated with these benefits, management must make a variety of 
estimates, including discount rates used to value certain liabilities, the expected return on plan assets set aside to fund 
these costs, the rate of compensation increase, employee turnover rates, retirement rates, health care trends, mortality 
rates, and other factors. These accounting estimates bear the risk of change due to the uncertainty attached to the 
estimate as well as the fact that these estimates are difficult to measure. Different estimates used by us could result in 
recognizing different amounts of expense over different periods of time and recovery in rates is expected.  

43 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We use third-party specialists to assist us in evaluating our assumptions as well as appropriately measure the costs and 
obligations associated with these retirement benefits. The discount rate and expected return on plan assets are based 
primarily on available investment yields and the historical performance of our plan assets. They are critical accounting 
estimates because they are subject to management's judgment and can materially affect net income. 

  Assumed return on assets. This assumption represents the rate of return on plan assets reflecting the average rate of 
earnings expected on the funds invested (or to be invested) to provide for the benefits included in the projected 
benefit obligation. For 2012, MGE used an assumed return on assets of 8.10% for pension and 7.26% for other 
postretirement benefits. In 2013, the pension asset assumption will remain at 8.10%. MGE will lower the 
postretirement benefit assumption from 7.26% to 6.79% in 2013. The annual expected rate of return is based on 
projected long-term equity and bond returns, maturities and asset allocations. Holding other assumptions constant, 
for every 1% reduction in the expected rate of return on plan assets, annual pension and other postretirement cost 
would increase by approximately $2.1 million, before taxes. 

  Discount rate. The discount rate represents the rate at which pension obligations could effectively be settled on a 
present-value basis. MGE uses high-grade bond yields as a benchmark for determining the appropriate discount 
rate. 

  Medical trend assumptions. The health care cost trend rate is the assumed rate of increase in per-capita health care 

charges. 

See Footnote 13 of the Notes to Consolidated Financial Statements for additional discussion of these plans. 

Income Tax Provision 

MGE Energy's and MGE's income tax provisions, including both current and deferred components, are based on 
estimates, assumptions, calculations, and interpretation of tax statutes for the current and future years. Determination of 
current-year federal and state income tax will not be settled for years. 

Management regularly makes assessments of tax return outcomes relative to financial statement tax provisions and 
adjusts the tax provisions in the period when facts become final. 

Additionally, in determining our current income tax provision we assess temporary differences resulting from differing 
treatments of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which 
are recorded in our balance sheets. When we maintain deferred tax assets, we assess the likelihood that these assets will 
be recovered through adjustments to future taxable income. To the extent we believe recovery is not more likely than 
not, we establish a valuation allowance. We record an allowance reducing the asset to a value we believe will be 
recoverable based on our expectation of future taxable income. We believe the accounting estimate related to the 
valuation allowance is a critical accounting estimate because it is highly susceptible to change from period to period as 
it requires management to make assumptions about our future income over the lives of the deferred tax assets, and the 
impact of increasing or decreasing the valuation allowance is potentially material to our results of operations.  

Accounting for uncertainty in income taxes applies to all tax positions and requires a recognition threshold and 
measurement standard for the financial statement recognition and measurement of a tax position taken, or expected to 
be taken, in an income tax return. The threshold is defined for recognizing tax return positions in the financial 
statements as "more likely than not" that the position is sustainable, based on its merits. Subsequent recognition, 
derecognition, and measurement is based on management's best judgment given the facts, circumstances and 
information available at the reporting date.  

Accounting for Derivative Instruments 

MGE accounts for derivative financial instruments, except those qualifying for the normal purchase normal sale 
exception, at their fair value on the balance sheet. Fair value is determined using current quoted market prices, except 
for the ten-year PPA which is valued utilizing an internally-developed pricing model. This model includes observable 
and unobservable inputs.  

MGE received approval from the PSCW to establish a regulatory asset or liability for the deferral of the effects of mark-
to-market accounting on contracts related to MGE's regulated operations. 

44 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Regulatory Assets/Liabilities 

Regulatory assets represent costs that have been deferred to future periods when it is probable that the regulator will 
allow future recovery of those costs through rates. MGE bases its assessment of recovery on precedents established by 
the regulatory body. Regulatory liabilities represent previous collections from customers that are expected to be 
refunded to customers in future periods. Regulatory assets and regulatory liabilities typically include deferral of energy 
costs, the normalization of income taxes, the deferral of certain operating expenses, and non-ARO removal cost. The 
accounting for these regulatory assets and liabilities is in accordance with regulatory accounting standards. 

MGE continually assesses whether the regulatory assets and liabilities meet the criteria for probability of future 
recovery or deferral. This assessment considers factors such as changes in the regulatory environment, recent rate orders 
to other regulated entities under the same jurisdiction, and the status of any pending or potential deregulation legislation. 
If future recovery of costs becomes no longer probable, the assets and liabilities would be recognized as current-period 
revenues or expenses. 

Amortization of regulatory assets and liabilities is provided over the recovery or deferral period as allowed in the related 
regulatory agreement. 

Adoption of Accounting Principles and Recently Issued Accounting Pronouncements - MGE Energy and MGE 

See Footnote 22 of the Notes to Consolidated Financial Statements for discussion of new accounting pronouncements. 

Item 7A. Quantitative and Qualitative Disclosures About Market Risk. 

MGE Energy and MGE are potentially exposed to market risk associated with interest rates, commodity prices, and 
equity returns. MGE currently has no exposure to foreign currency risk. MGE manages some risk exposure through risk 
management policies and the use of derivative instruments. MGE's risk management policy prohibits speculative 
trading transactions. 

Commodity Price Risk 

MGE has commodity price risk exposure with respect to the price of natural gas, electricity, coal, emission credits, and 
oil. MGE employs established policies and procedures to reduce the market risks associated with changing commodity 
prices. MGE's commodity risks are somewhat mitigated by the current ratemaking process in place for recovering 
electric fuel cost, purchased energy costs, and the cost of natural gas. MGE's electric fuel costs are subject to fuel rules 
established by the PSCW.  

MGE's electric operations burn natural gas in several of its peaking power plants and, in many cases, the cost of 
purchased power is tied to the cost of natural gas. MGE bears regulatory risk for the recovery of such fuel and 
purchased power costs when they are higher than the base rate established in its current rate structure.  

The PSCW approved new fuel rules that became effective January 1, 2011. The new rules require the PSCW and 
Wisconsin utilities to defer electric fuel-related costs that fall outside a symmetrical cost tolerance band. Any over/under 
recovery of the actual costs is determined on an annual basis and will be adjusted in future billings to electric retail 
customers. Under the electric fuel rules, MGE is required to defer the benefit of lower costs if the actual electric fuel 
costs fall outside the lower end of the range and would defer costs, less any excess revenues, if the actual electric fuel 
costs exceeded the upper end of the range. Excess revenues are defined as revenues in the year in question that provide 
MGE with a greater return on common equity than authorized by the PSCW in MGE's latest rate order. The range is 
defined by the PSCW and has been modified throughout the years based on market conditions and other relevant 
factors. Currently, MGE is subject to a plus or minus 2% range. MGE assumes the risks and benefits of variances that 
are within the cost tolerance band. For 2012, fuel and purchased power costs included in MGE's base fuel rates are 
$100.7 million. See Footnote 17 of Notes to Consolidated Financial Statements for additional information. 

MGE recovers the cost of natural gas in its gas segment through the purchased gas adjustment clause (PGA). Under the 
PGA, MGE is able to pass through to its gas customers the cost of gas.  

MGE also reduces price risk caused by market fluctuations via physical contracts and financial derivative contracts, 
including futures, swaps, options, forwards, and other contractual commitments. The maximum length of time over 
which cash flows related to energy commodities can be hedged under applicable PSCW approvals is four years. 

45 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
MGE has financial gas and electric commodity contracts to hedge commodity price risk in the gas and electric 
segments. These contracts are primarily comprised of exchange-traded option and future contracts. MGE also holds 
FTRs, which are used to hedge the risk of increased transmission congestion charges. At December 31, 2012, the fair 
value of these instruments exceeded their cost basis by $0.3 million. Under the PGA clause and electric fuel rules, MGE 
may include in the costs of fuel (natural gas or power) the costs and benefits of the aforementioned fuel price risk 
management tools. Because these costs/benefits are recoverable, the related unrealized loss/gain has been deferred on 
the balance sheet as a regulatory asset/liability. 

MGE has also entered into a ten-year purchased power agreement that provides MGE with firm capacity and energy 
that began on June 1, 2012, and ends on May 31, 2022 (the "base term"). The agreement also allows MGE an option to 
extend the contract after the base term. The agreement is considered a derivative contract and is recognized at its fair 
value on the balance sheet. The fair value of the contract at December 31, 2012, reflects a loss position of $72.6 million. 

Interest Rate Risk 

Both MGE Energy and MGE may have short term borrowings at varying interest rates. MGE issues commercial paper 
for its short-term borrowings, while MGE Energy draws from its current credit facility to meet its short-term borrowing 
needs (see Footnote 10 of the Notes to Consolidated Financial Statements). Borrowing levels vary from period to period 
depending upon capital investments and other factors. Future short-term interest expense and payments will reflect both 
future short-term interest rates and borrowing levels. MGE Energy and MGE manage interest rate risk by limiting their 
variable rate exposure and continually monitoring the effects of market changes on interest rates. MGE is not exposed to 
changes in interest rates on a substantial portion of its long-term debt until that debt matures and is refinanced at market 
rates. 

Equity Price Risk - Pension-Related Assets 

MGE currently funds its liabilities related to employee benefits through trust funds. These funds, which include 
investments in debt and equity securities, are managed by various investment managers. Changes in market value of 
these investments can have an impact on the future expenses related to these liabilities. Holding other assumptions 
constant, for every 1% reduction in the expected rate of return on plan assets, annual pension and other postretirement 
cost would increase by approximately $2.1 million, before taxes. MGE's risk of expense and annuity payments, as a 
result of changes in the market value of the trust funds, is mitigated in part through future rate actions by the PSCW. 
The value of employee benefit plans trusts' assets have increased in value by approximately 14.5% during the year 
ended December 31, 2012, and 2.1% during the year ended December 31, 2011. 

Credit Risk - Counterparty 

Credit risk is the loss that may result from counterparty nonperformance. MGE is exposed to credit risk primarily 
through its merchant energy business. MGE uses credit policies to manage its credit risk, which include utilizing an 
established credit approval process, monitoring counterparty limits, employing credit mitigation measures such as 
collateral or prepayment arrangements, and using netting agreements. 

Due to the possibility of extreme volatility in the prices of energy commodities and derivatives, the market value of 
contractual positions with individual counterparties could exceed established credit limits or collateral provided by 
those counterparties. If such a counterparty were then to fail to perform its obligations under its contract (for example, 
fail to deliver the electricity MGE originally contracted for), MGE could sustain a loss that could have a material impact 
on its financial results. 

Additionally, if a counterparty were to default and MGE were to liquidate all contracts with that entity, MGE's credit 
loss would include the loss in value of mark-to-market contracts; the amount owed for settled transactions; and 
additional payments, if any, to settle unrealized losses on accrual contracts. As of December 31, 2012, no counterparties 
have defaulted. 

MGE is obligated to provide service to all electric and gas customers within its respective franchised territories. MGE's 
franchised electric territory includes a 316 square-mile area in Dane County, Wisconsin, and MGE's franchised gas 
territory includes a service area covering 1,631 square miles in Wisconsin. Based on results for the year ended 
December 31, 2012, no one customer constituted more than 10% of total operating revenues for MGE Energy and 
MGE. Credit risk for electric and gas is managed by MGE's credit and collection policies, which are consistent with 
state regulatory requirements. 

46 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Cash, cash equivalents, and customer accounts receivable are the financial instruments that potentially subject 
MGE Energy and MGE to concentrations of credit risk. MGE Energy and MGE place their cash and cash equivalents 
with high credit-quality financial institutions. MGE has limited concentrations of credit risk from customer accounts 
receivable because of the large number of customers and relatively strong economy in its service territory.

Report of Independent Registered Public Accounting Firm 

To the Board of Directors and Shareholders of MGE Energy, Inc.: 

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 MGE Energy, Inc. and its subsidiaries at December 31, 2012 and 2011, 
and the results of their operations and their cash flows for each of the three years in the period ended December 31, 
2012, in conformity with accounting principles generally accepted in the United States of America. In addition, in our 
opinion, the financial statement schedules listed in the index appearing under Item 15(a)(2) present fairly, in all material 
respects, the information set forth therein when read in conjunction with the related consolidated financial statements. 
Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting 
as of December 31, 2012, based on criteria established in Internal Control - Integrated Framework issued by the 
Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is 
responsible for these financial statements and financial statement schedules, for maintaining effective internal control 
over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included 
in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to 
express opinions on these financial statements, on the financial statement schedules, 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.

Report of Independent Registered Public Accounting Firm 

To the Board of Directors and Shareholder of Madison Gas and Electric Company: 

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 Madison Gas and Electric Company and its subsidiaries at December 31, 
2012 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended 
December 31, 2012, in conformity with accounting principles generally accepted in the United States of America. In 
addition, in our opinion, the financial statement schedule listed in the index appearing under Item 15(a)(2) presents 
fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated 
financial statements. These financial statements and financial statement schedule are the responsibility of the 
Company's management. Our responsibility is to express an opinion on these financial statements and financial 
statement schedule based on our audits. We conducted our audits of these statements in accordance with the standards 
of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform 
the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An 
audit includes 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. We believe that our audits provide a reasonable basis for our opinion.

Notes to Consolidated Financial Statements 
December 31, 2012, 2011, and 2010 

This report is a combined report of MGE Energy and MGE. The notes to the consolidated financial statements that 
follow include consolidated MGE Energy Footnotes and certain Footnotes related to MGE as signified below. 

1. 

Summary of Significant Accounting Policies. 

a.  Basis of Presentation - MGE Energy and MGE. 

The consolidated financial statements are prepared in conformity with accounting principles generally 
accepted in the United States of America (GAAP), which give recognition to the rate making accounting 
policies for regulated operations prescribed by the regulatory authorities having jurisdiction, principally the 
PSCW and FERC. MGE's accounting records conform to the FERC uniform system of accounts.  

b.  Principles of Consolidation - MGE Energy and MGE. 

MGE, a wholly owned subsidiary of MGE Energy, is a regulated electric and gas utility headquartered in 
Madison, Wisconsin. MGE Energy and MGE consolidate all majority owned subsidiaries in which it has 
controlling influence. MGE is the majority owner of MGE Transco. MGE Transco is a nonregulated entity 
formed to manage the investment in ATC.  

Wholly owned subsidiaries of MGE Energy include CWDC, MAGAEL, MGE Construct, and MGE Power. 
MGE Power owns 100% of MGE Power Elm Road and MGE Power West Campus. MGE Power and its 
subsidiaries are part of MGE Energy's nonregulated energy operations, which were formed to own and lease 
electric generation projects to assist MGE. 

MGE Energy and MGE consolidate variable interest entities (VIEs) for which it is the primary beneficiary. 
Variable interest entities are legal entities that possess any of the following characteristics: equity investors 
who have an insufficient amount of equity at risk to finance their activities, equity owners who do not have 
the power to direct the significant activities of the entity (or have voting rights that are disproportionate to 
their ownership interest), or equity holders who do not receive expected losses or returns significant to the 
VIE. If MGE Energy or MGE is not the primary beneficiary and an ownership interest is held, the VIE is 
accounted for under the equity method of accounting. When assessing the determination of the primary 
beneficiary, all relevant facts and circumstances are considered, including: the power, through voting or 
similar rights, to direct the activities of the VIE that most significantly impact the VIE's economic 
performance and the obligation to absorb the expected losses and/or the right to receive the expected returns 
of the VIE. Ongoing reassessments of all VIEs are performed to determine if the primary beneficiary status 
has changed. MGE has consolidated MGE Power Elm Road and MGE Power West Campus. Both entities 
are VIEs. MGE is considered the primary beneficiary of these entities as a result of contractual agreements. 
See Footnote 2 to the Consolidated Financial Statements for more discussion of these entities. 

The consolidated financial statements reflect the application of certain accounting policies described in this 
note. All significant intercompany accounts and transactions have been eliminated in consolidation.  

c.  Use of Estimates - MGE Energy and MGE. 

In order to prepare consolidated financial statements in conformity with GAAP, management must make 
estimates and assumptions. These estimates could affect reported amounts of assets, liabilities, and 
disclosures at the date of the financial statements, as well as the reported amounts of revenues and expenses 
during the reporting periods. Actual results could differ from management's estimates. 

d.  Cash Equivalents and Restricted Cash - MGE Energy and MGE. 

MGE Energy and MGE consider all highly liquid investments purchased with an original maturity of three 
months or less to be cash equivalents.  

MGE has certain cash accounts that are restricted to uses other than current operations and designated for a 
specific purpose. MGE's restricted cash accounts include cash held by trustees for certain employee benefits. 
These are included in other current assets.

e.  Receivable – Margin Account - MGE Energy and MGE. 

Cash amounts held by counterparties as margin for certain financial transactions are recorded as receivable – 
margin account. The balance is shown net of any collateral posted against derivative positions. As of 
December 31, 2012, there was no collateral posted against derivative positions. As of December 31, 2011, 
the balance is shown net of $3.0 million collateral. Changes in this cash account are considered cash flows 
from operating activities to match with the costs being hedged. The costs being hedged are fuel for electric 
generation, purchased power, and cost of gas sold. 

f.  Trade Receivables, Allowance for Doubtful Accounts, and Concentration Risk - MGE Energy and 

MGE. 

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. However, a 1% late 
payment charge is recorded on all receivables unpaid after the due date. The allowance for doubtful accounts 
associated with these receivables represents our best estimate of the amount of probable credit losses in our 
existing accounts receivable. We determine our allowance for doubtful accounts based on historical write-off 
experience, regional economic data, and review of the accounts receivable aging.  

MGE is obligated to provide service to all electric and gas customers within its franchised territories. MGE's 
franchised electric territory includes a 316 square-mile area in Dane County, Wisconsin, and MGE's 
franchised gas territory includes a service area covering 1,631 square-miles in Wisconsin. MGE manages 
this concentration and the related credit risk through its credit and collection policies, which are consistent 
with state regulatory requirements. 

g. 

Inventories - MGE Energy and MGE. 

Inventories consist of natural gas in storage, fossil fuels, materials and supplies, SO2 allowances, and 
renewable energy credits (RECs). MGE values natural gas in storage, fossil fuels, and materials and supplies 
using average cost.  

SO2 emission allowances are included in inventory and are recorded at weighted average cost. These 
allowances are charged to fuel expense as they are used in operations. MGE's emission allowance balances 
as of December 31, 2012 and 2011, were $0.1 million and $0.2 million, respectively. 

REC allowances are included in inventory and are recorded based on specific identification. These 
allowances are charged to purchase power expense as they are used in operations. MGE's REC allowance 
balances as of December 31, 2012 and 2011, were $0.5 million and $0.3 million, respectively. 

h.  Regulatory Assets and Liabilities - MGE Energy and MGE. 

Regulatory assets and regulatory liabilities are recorded consistent with regulatory treatment. Regulatory 
assets represent costs which are deferred due to the probable future recovery from customers through 
regulated rates. Regulatory liabilities represent the excess recovery of costs or accrued credits which were 
deferred because MGE believes it is probable such amounts will be returned to customers through future 
regulated rates. Regulatory assets and liabilities are amortized in the consolidated statements of income 
consistent with the recovery or refund included in customer rates. MGE believes that it is probable that its 
recorded regulatory assets and liabilities will be recovered and refunded, respectively, in future rates. See 
Footnote 6 for further information. 

i.  Debt Issuance Costs - MGE Energy and MGE. 

Premiums, discounts, and expenses incurred with the issuance of outstanding long-term debt are amortized 
over the life of the debt issue. Any call premiums or unamortized expenses associated with refinancing 
higher-cost debt obligations used to finance utility-regulated assets and operations are amortized consistent 
with regulatory treatment of those items. 

j.  Property, Plant, and Equipment - MGE Energy and MGE. 

Property, plant, and equipment is recorded at original cost. Cost includes indirect costs consisting of payroll 
taxes, pensions, postretirement benefits, other fringe benefits, and administrative and general costs. Also, 
included in the cost is AFUDC for utility property and capitalized interest for nonregulated property.  

60 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Additions for significant replacements of property are charged to property, plant, and equipment at cost; and 
minor items are charged to maintenance expense. The cost of removal of utility property less salvage value is 
charged to accumulated depreciation when property is retired. Depreciation rates on utility property are 
approved by the PSCW, based on the estimated economic lives of property, and include estimates for 
salvage value and removal costs. Depreciation rates on nonregulated property are based on the estimated 
economic lives of the property. See Footnote 3 for further information. 

Provisions at composite straight-line depreciation rates approximate the following percentages for the cost of 
depreciable property: 

Electric 
Gas  
Nonregulated  

2012   
2.9 % 
1.7 % 
2.3 % 

2011   
3.2 % 
1.6 % 
2.3 % 

2010   
3.3 % 
1.7 % 
2.3 % 

k.  Repairs and Maintenance Expense - MGE Energy and MGE. 

MGE utilizes the direct expensing method for planned major maintenance projects. Under this method, MGE 
expenses all costs associated with major planned maintenance activities as incurred. 

l.  Purchased Gas Adjustment Clause - MGE Energy and MGE. 

MGE's natural gas rates are subject to a fuel adjustment clause designed to recover or refund the difference 
between the actual cost of purchased gas and the amount included in rates. Differences between the amounts 
billed to customers and the actual costs recoverable are deferred and recovered or refunded in future periods 
by means of prospective monthly adjustments to rates. At December 31, 2012, MGE had under collected 
$0.1 million. At December 31, 2011, MGE had over collected $0.9 million. These amounts were netted in 
other current liabilities on the consolidated balance sheet. 

m.  Revenue Recognition - MGE Energy and MGE. 

Operating revenues are recorded as service is rendered or energy is delivered to customers. Meters are read 
on a systematic basis throughout the month based on established meter-reading schedules. At the end of the 
month, MGE accrues an estimate for the unbilled amount of energy delivered to customers. The unbilled 
revenue estimate is based on daily system demand volumes, weather factors, estimated line losses, estimated 
customer usage by class, and applicable customer rates.  

n.  Utility Cost Recovery - MGE Energy and MGE. 

MGE's rates include a provision for fuel costs. The PSCW allows Wisconsin utilities to defer electric fuel-
related costs, less excess revenues, that fall outside a symmetrical cost tolerance band. Any over/under 
recovery of the actual costs is determined on an annual basis and will be adjusted in future billings to electric 
retail customers. Such deferred amounts will be recognized in "Purchased Power Expense" in MGE Energy's 
and MGE's income statement each period. The cumulative effects of these deferred amounts will be recorded 
in current "Regulatory assets" or current "Regulatory liabilities" on MGE Energy's and MGE's consolidated 
balance sheets until they are reflected in future billings to customers. See Footnote 17.b for further 
information. 

o.  Allowance for Funds Used During Construction - MGE Energy and MGE. 

Allowance for funds used during construction is included in utility plant accounts and represents the cost of 
borrowed funds used during plant construction and a return on shareholders' capital used for construction 
purposes. In the consolidated income statements, the cost of borrowed funds (AFUDC-debt) is presented as 
an offset to interest expense and the return on shareholders' capital (AFUDC-equity funds) is shown as an 
item within other income. As approved by the PSCW, MGE capitalized AFUDC-debt and equity on 50% of 
applicable average construction work in progress during 2012, 2011, and 2010 at 8.36%. Also, MGE 
received specific approval to recover 100% AFUDC on certain environmental costs for Columbia. Although 
the allowance does not represent current cash income, it is recovered under the ratemaking process over the 
service lives of the related properties. See Footnote 20 for further information regarding Columbia AFUDC.

p.  Investments - MGE Energy and MGE. 

Investments in limited liability companies that have specific ownership accounts in which MGE Energy or 
MGE's ownership interest is more than minor are accounted for using the equity method. All other 
investments are carried at fair value or at cost, as appropriate. See Footnote 4 for further information. 

q.  Capitalized Software Costs - MGE Energy and MGE. 

Property, plant, and equipment includes the capitalized costs of internal use software totaling $14.5 million 
at December 31, 2012 and 2011. During 2012 and 2011, MGE recorded $1.3 million and $1.8 million, 
respectively, of amortization expense related to these costs. These costs are amortized on a straight-line basis 
over the estimated useful lives of the assets. For internal use software, the useful lives range from five to ten 
years. 

r. 

Impairment of Long-Lived Assets - MGE Energy and MGE. 

MGE reviews plant and equipment and other property for impairment when events or changes in 
circumstances indicate that the carrying amount of the assets may not be recoverable. MGE's policy for 
determining when long-lived assets are impaired is to recognize an impairment loss if the sum of the 
expected future cash flows (undiscounted and without interest charges) from an asset are less than the 
carrying amount of that asset. If an impairment loss is recognized, the amount that will be recorded will be 
measured as the amount by which the carrying amount of the asset exceeds the fair value of the asset. There 
is no impairment of long-lived assets at December 31, 2012. 

s. 

Income Taxes and Excise Taxes - MGE Energy and MGE. 

Income taxes 
Under the liability method, income taxes are deferred for all temporary differences between pretax financial 
and taxable income and between the book and tax basis of assets and liabilities using the tax rates scheduled 
by law to be in effect when the temporary differences reverse. Future tax benefits are recognized to the 
extent that realization of such benefits is more likely than not. A valuation allowance is recorded for those 
benefits that do not meet this criterion. 

Accounting for uncertainty in income taxes applies to all tax positions and requires a recognition threshold 
and measurement standard for the financial statement recognition and measurement of a tax position taken, 
or expected to be taken, in an income tax return. The threshold is defined for recognizing tax return positions 
in the financial statements as "more likely than not" that the position is sustainable, based on its merits. 
Subsequent recognition, derecognition, and measurement is based on management's best judgment given the 
facts, circumstances, and information available at the reporting date. 

Regulatory and accounting principles have resulted in a regulatory liability related to income taxes. Excess 
deferred income taxes result from past taxes provided at rates higher than current rates. The income tax 
regulatory liability and deferred investment tax credit reflect the revenue requirement associated with the 
return of these tax benefits to customers. 

Investment tax credits from regulated operations are amortized over related property service lives. 

Excise taxes 
MGE Energy, through its utility operations, pays a state license fee tax in lieu of property taxes on property 
used in utility operations. License fee tax is calculated as a percentage of adjusted operating revenues of the 
prior year. The electric tax rate is 3.19% for retail sales and 1.59% for sales of electricity for resale by the 
purchaser. The tax rate on sales of natural gas is 0.97%. The tax is required to be estimated and prepaid in 
the year prior to its computation and expensing. License fee tax expense, included in other general taxes, was 
$13.5 million, $12.9 million, and $12.6 million for the years ended December 31, 2012, 2011, and 2010, 
respectively. 

Operating income taxes, including tax credits and license fee tax are included in rates for utility related 
items.

t.  Share-Based Compensation - MGE Energy and MGE. 

Under MGE Energy's Performance Unit Plan, eligible participants may receive performance units that entitle 
the holder to receive a cash payment equal to the value of a designated number of shares of MGE Energy's 
common stock, plus dividend equivalent payments thereon, at the end of the set performance period. Per the 
plan's provisions, these awards are subject to a prescribed vesting schedule and must be settled in cash. 
Accordingly, no new shares of common stock are issued in connection with the plan.  

MGE Energy and MGE initially measure the cost of the employee services received in exchange for a 
performance unit award based on the current market value of MGE Energy common stock. The fair value of 
the award is subsequently re-measured at each reporting date through the settlement date. Changes in fair 
value during the requisite period are recognized as compensation cost over that period. 

u.  Treasury Stock - MGE Energy. 

Treasury shares are recorded at cost. Any shares of common stock repurchased are held as treasury shares 
unless cancelled or reissued. No treasury shares are outstanding as of December 31, 2012. 

v.  Comprehensive Income - MGE Energy and MGE. 

Total comprehensive income includes all changes in equity during a period except those resulting from 
investments by and distributions to shareholders. Comprehensive income is reflected in the consolidated 
statements of comprehensive income. 

w.  Derivative and Hedging Instruments - MGE Energy and MGE. 

As part of regular operations, MGE enters into contracts including options, swaps, futures, forwards, and 
other contractual commitments to manage its exposure to interest rates, commodity prices, and gas revenues. 
MGE recognizes all derivatives in the consolidated balance sheets at fair value, with changes in the fair 
value of derivative instruments to be recorded in current earnings or deferred in accumulated other 
comprehensive income (loss), depending on whether a derivative is designated as, and is effective as, a 
hedge and on the type of hedge transaction. Derivative activities are in accordance with the company's risk 
management policy.  

If the derivative qualifies for regulatory deferral, the derivatives are marked to fair value and any resulting 
loss or gain is offset with a corresponding regulatory asset or liability. Cash flows from such derivative 
instruments are classified on a basis consistent with the nature of the underlying hedged item. 

2. 

Variable Interest Entities - MGE Energy and MGE. 

a.  MGE Power Elm Road. 

MGE Power Elm Road is not a subsidiary of MGE; however, it has been consolidated in the financial 
statements of MGE. MGE Power Elm Road was created for the purpose of owning new generating assets. 
MGE Power Elm Road's sole principal assets are an 8.33% undivided ownership interest in two 615 MW 
coal-fired generating plants located in Oak Creek, Wisconsin, which it leases to MGE pursuant to long-term 
leases. Based on the nature and terms of the contractual agreements, MGE is expected to absorb a majority 
of the expected losses, residual value, or both, associated with the ownership of MGE Power Elm Road and 
therefore holds a variable interest in MGE Power Elm Road, even though it has no equity interest in MGE 
Power Elm Road. MGE Energy and MGE consolidate VIEs for which they are the primary beneficiary. 
MGE has the power to direct the activities that most significantly impact the Elm Road Units' economic 
performance and is also the party most closely associated with MGE Power Elm Road. As a result, MGE is 
the primary beneficiary.

Long-term debt consists of $73.3 million of senior secured notes that require that MGE Power Elm Road 
maintain a projected and actual debt service coverage ratio at the end of any calendar quarter of not less than 
1.25 to 1.00 for the trailing 12-month period. The debt is secured by a collateral assignment of lease 
payments that MGE is making to MGE Power Elm Road for use of the Elm Road Units pursuant to the 
related long-term leases. As of December 31, 2012, MGE Power Elm Road is in compliance with the 
covenant requirements. 

MGE has been and will continue to recover in rates the lease payments made to MGE Power Elm Road. 
Unit 1 entered commercial operation in February 2010, and Unit 2 entered commercial operation in 
January 2011. MGE received approval from the PSCW to collect in rates the carrying costs incurred by 
MGE Power Elm Road. The total carrying costs on the Elm Road Units is $62.2 million. MGE began 
collecting the carrying costs in rates in 2006. These amounts are being collected over multiple years. Of 
these costs, $17.0 million relates to the capitalized interest and the debt portion of the units. These costs will 
be recognized over the period in which the generating units will be depreciated. The remaining $45.2 million 
represents the equity portion and is being recognized over the period allowed for recovery in rates.  

b.  MGE Power West Campus. 

MGE Power West Campus is not a subsidiary of MGE; however, it has been consolidated in the financial 
statements of MGE. MGE Power West Campus was created for the purpose of owning new generating 
assets. MGE Power West Campus' sole principal asset is the WCCF, which it leases to MGE pursuant to a 
long-term lease. MGE is responsible for operation of the plant during the term of the lease. Based on the 
nature and terms of these contractual relationships, MGE absorbs a majority of the expected losses, residual 
value, or both, associated with the ownership and operation of the WCCF and therefore holds a variable 
interest in MGE Power West Campus, even though it has no equity interest in MGE Power West Campus. 
MGE has the power to direct the activities that most significantly impact WCCF's economic performance 
and is also the party most closely associated with MGE Power West Campus. As a result, MGE is the 
primary beneficiary. At December 31, MGE has included the following significant accounts on its balance 
sheet related to its interest in this VIE:

Long-term debt consists of $50 million of senior secured notes that require that MGE Power West Campus 
maintain a projected debt service coverage ratio of not less than 1.25 to 1.00 and debt to total capitalization 
ratio of not more than .65 to 1.00. The debt is secured by a collateral assignment of lease payments that 
MGE is making to MGE Power West Campus for use of the cogeneration facility pursuant to the long-term 
lease. As of December 31, 2012, MGE Power West Campus is in compliance with the covenant 
requirements. 

MGE has been and will continue to recover lease payments made to MGE Power West Campus in rates. 
Also, MGE received approval from the PSCW to collect approximately $12.1 million in carrying costs 
incurred by MGE Power West Campus during construction of the facility. The carrying costs are being 
recovered in rates over a 10 year period that started in 2005.

c.  Other Variable Interest Entities. 

MGE has a variable interest in two entities through purchase power agreements relating to purchased energy 
from the facilities. As of December 31, 2012 and 2011, MGE had 65 megawatts and 50 megawatts, 
respectively, of capacity available under these agreements. MGE evaluated the variable interest entities for 
possible consolidation. The interest holder is considered the primary beneficiary of the entity and is required 
to consolidate the entity if the interest holder has the power to direct the activities that most significantly 
impact the economics of the variable interest entity. MGE examined qualitative factors such as the length of 
the remaining term of the contracts compared with the remaining lives of the plants, who has the power to 
direct the operations and maintenance of the facilities, and other factors, and determined MGE is not the 
primary beneficiary of the variable interest entities. There is not a significant potential exposure to loss as a 
result of involvement with these two variable interest entities.

b.  ATC. 

ATC owns and operates electric transmission facilities primarily in Wisconsin. MGE received an interest in 
ATC when it, like other Wisconsin electric utilities, contributed its electric transmission facilities to ATC. 
That interest is presently held by MGE Transco, which is jointly owned by MGE Energy and MGE. 

MGE Transco has accounted for its investment in ATC under the equity method of accounting. For the years 
ended December 31, 2012, 2011, and 2010, MGE Transco recorded equity earnings from the investment in 
ATC of $9.1 million, $8.6 million, and $8.5 million, respectively. Dividend income received from ATC was 
$7.1 million for the year ended December 31, 2012, and $6.7 million for both the years ended December 31, 
2011 and 2010. During the years ended December 31, 2012, 2011, and 2010, MGE Transco made 
$2.1 million, $0.9 million, and $0.7 million, respectively, in capital contributions to ATC.  

During March 2010, MGE sold a parcel of land in Middleton, Wisconsin to ATC for $2.7 million, resulting 
in a gain of $2.6 million (pretax) in other income. The transaction was approved by the PSCW. 

At December 31, 2012 and 2011, MGE Transco held a 3.6% ownership interest in ATC. MGE Transco's 
investment balance is different from the amount of the underlying equity in the net assets of ATC. This 
difference is attributable to the allocation of certain tax impacts related to the initial asset transfer. 

At December 31, 2012 and 2011, MGE is the majority owner, and MGE Energy, the holding company, is the 
minority owner of MGE Transco. MGE Energy's proportionate share of the equity and net income of MGE 
Transco is classified within the MGE financial statements as noncontrolling interest.  

ATC's summarized financial data for the years ended December 31, 2012, 2011, and 2010, is as follows:

Joint Plant Ownership - MGE Energy and MGE. 

a.  Columbia. 

MGE and two other utilities jointly own Columbia, a coal-fired generating facility located in Portage, 
Wisconsin, which accounts for 29% (225 MW) of MGE's net summer rated capacity. Power from this 
facility is shared in proportion to each company's ownership interest. MGE has a 22% ownership interest in 
Columbia. The other owners are WPL, which operates Columbia, and WPSC. MGE's share of fuel, 
operating, and maintenance expenses for Columbia were $36.3 million, $37.1 million, and $35.9 million for 
the years ended December 31, 2012, 2011, and 2010, respectively. See Footnote 18 for discussion of MGE's 
future capital commitments in respect to the environmental projects at Columbia as a result of this ownership 
interest. 

Each owner provides its own financing and reflects its respective portion of facilities and operating costs in 
its financial statements. MGE's interest in Columbia, included in its gross utility plant in service, and the 
related accumulated depreciation reserves at December 31 were as follows:

b.  Elm Road. 

MGE Power Elm Road owns an 8.33% ownership interest in each of two 615 MW coal-fired generating 
units in Oak Creek, Wisconsin. Unit 1 entered commercial operation on February 2, 2010. Unit 2 entered 
commercial operation on January 12, 2011. MGE Power Elm Road's sole principal asset is that ownership 
interest in those generating units. MGE Power Elm Road's interest in the Elm Road Units is leased to MGE 
pursuant to long-term leases. 

The remainder of the ownership interest in the Elm Road Units is held by two other entities, one of which is 
also responsible for the Units' operation. Each owner provides its own financing and reflects its respective 
portion of the facility and costs in its financial statements. MGE's share of fuel, operating, and maintenance 
expenses for the Elm Road Units were $13.2 million, $18.0 million, and $7.4 million for the years ended 
December 31, 2012, 2011, and 2010, respectively. MGE Power Elm Road's interest in the portion of the Elm 
Road Units in-service and the related accumulated depreciation reserves at December 31 were as follows:

c.  WCCF. 

MGE Power West Campus and the UW jointly own the West Campus Cogeneration Facility located on the 
UW campus in Madison, Wisconsin. MGE Power West Campus owns 55% of the facility and the UW owns 
45% of the facility. The UW owns a controlling interest in the chilled-water and steam plants, which are 
used to meet the growing needs for air-conditioning and steam-heat capacity for the UW campus. MGE 
Power West Campus owns a controlling interest in the electric generation plant, which is leased and operated 
by MGE.

MGE expects to recover its regulatory assets and return its regulatory liabilities through rates charged to 
customers based on PSCW decisions made during the ratemaking process or based on PSCW long-standing 
policies and guidelines. The adjustments to rates for these regulatory assets and liabilities will occur over the 
periods either specified by the PSCW or over the corresponding period related to the asset or liability. We believe 
it is probable that MGE will continue to recover from customers the regulatory assets described above based on 
prior and current ratemaking treatment for such costs. All regulatory assets for which a cash outflow had been 
made are earning a return, except for amounts expended for environmental costs. 

Asset Retirement Obligation

Conservation Costs 
MGE has received regulatory treatment for certain conservation expenditures. The expenditures are used for 
demand-side management programs to promote energy efficiency on the customer's premises. Costs for demand-
side management programs are estimated in MGE's rates utilizing escrow accounting. The escrow accounting 
allows the utility to true-up its actual costs incurred and reflect the amount of the true-up in its next rate case 
filing and amortize the amount over the rate case period. The customer service - conservation escrow has been 
discontinued beginning January 1, 2013. These costs will be trued up in MGE's next rate case. 

Debt Related Costs 
This balance includes debt issuance costs of extinguished debt and other debt related expenses. The PSCW has 
allowed rate recovery on unamortized issuance costs for extinguished debt facilities. When the facility replacing 
the old facility is deemed by the PSCW to be more favorable for the ratepayers, the PSCW will allow rate 
recovery of any unamortized issuance costs related to the old facility. These amounts are recovered over the term 
of the new facility. 

Other debt related expenses include the difference between interest earned and interest expensed on debt during 
construction. The amounts are currently being amortized over the remaining life of the debt as part of the rate 
recovery allowed by the PSCW.  

Derivatives 
MGE has physical and financial contracts that are defined as derivatives. The amounts recorded for the net mark-
to-market value of the commodity based contracts is offset with a corresponding regulatory asset or liability 
because these transactions are part of the PGA or fuel rules clause authorized by the PSCW. A significant portion 
of the recorded amount is related to the ten-year purchased power agreement that provides MGE with firm 
capacity and energy during a base term from June 1, 2012, through May 31, 2022. This agreement is accounted 
for as a derivative contract. 

Elm Road 
In 2010, MGE started collecting lease payments based on the expected commercial operation dates of the Elm 
Road Units. The difference between the expected start date and the actual start date of the lease payments will be 
returned to customers in the next base rate case. Also, MGE has deferred payments made to MGE Power Elm 
Road for carrying costs during construction of the facility, management fees, community impact mitigation, and 
operating costs. MGE is collecting carrying costs in rates over a six year period beginning in 2010. All other 
costs are collected in rates over a one to two year period.  

Environmental Costs 
MGE has been allowed to defer actual costs on certain environmental matters, including clean up of two landfill 
sites and legal expenditures pertaining to the response to the EPA Clean Air Act enforcement matter at 
Columbia. For further discussion of the Columbia Clean Air Act litigation, see Footnote 18.e. 

Medicare Part D Subsidy 
In the first quarter of 2010, the Patient Protection and Affordable Care Act (the PPACA) was enacted. The 
PPACA changed the tax treatment of federal subsidies paid to sponsors of retiree health benefit plans. As a result 
of the PPACA, these subsidy payments will become taxable in 2013. MGE received rate recovery beginning in 
2013 of the incremental tax expense as a result of this legislation.  

Pension and OPRB Costs 
The PSCW has allowed MGE to defer the 2009 incremental pension and OPRB costs above the amounts 
recovered in rates. Recovery of the costs began in 2010. The costs are being recovered in rates over a four year 
period for electric portion and a two year period for gas portion. 

Tax Recovery Related to AFUDC Equity 
AFUDC equity represents the after-tax equity cost associated with utility plant construction and results in a 
temporary difference between the book and tax basis of such plant. It is probable under PSCW regulation that 
MGE will recover in future rates the future increase in taxes payable represented by the deferred income tax 
liability. The amounts will be recovered in rates over the depreciable life of the asset for which AFUDC was 
applied. Tax recovery related to AFUDC equity represents the revenue requirement related to recovery of these 
future taxes payable, calculated at current statutory tax rates. 

69 

 
 
 
 
 
 
 
 
 
 
 
 
 
Unfunded Pension and Other Postretirement Liability 
MGE is required to recognize the unfunded status of defined benefit pension and other postretirement pension 
plans as a net liability or asset on the balance sheet with an offset to other comprehensive income. The amount 
normally charged to other comprehensive income for the unfunded status represents future expenses that are 
expected to be recovered in rates.  

Deferred Fuel Savings  
The PSCW approved new fuel rules that became effective January 1, 2011. The new rules require the PSCW and 
Wisconsin utilities to defer electric fuel-related costs that fall outside a symmetrical cost tolerance band. Any 
over/under recovery of the actual costs is determined on an annual basis and will be adjusted in future billings to 
electric retail customers. Under the electric fuel rules, MGE is required to defer the benefit of lower costs if the 
actual fuel rules costs fall outside the lower end of the range and would defer costs, less any excess revenues, if 
the actual fuel rules costs exceeded the upper end of the range. Excess revenues are defined as revenues in the 
year in question that provide MGE with a greater return on common equity than authorized by the PSCW in 
MGE's latest rate order. See Footnote 17.b for further discussion.  

Income Taxes  
Excess deferred income taxes result from past taxes provided at rates higher than current rates. The regulatory 
liability and deferred investment tax credit reflects the revenue requirement associated with the return of these tax 
benefits to customers.  

Non-ARO Removal Costs 
In connection with accounting for asset retirement obligations, companies are required to reclassify cumulative 
collections for non-ARO removal costs as a regulatory liability, with an offsetting entry to accumulated 
depreciation. Under the current rate structure, these removal costs are being recovered as a component of 
depreciation expense. 

Renewable Energy Credits 
MGE receives renewable energy credits from certain purchase power. The value of the credits are recorded as 
inventory and expensed when the credit is redeemed or expired. A regulatory liability has been established for 
the value of the renewable energy credits included in inventory. In Wisconsin, renewable energy credits expire 
four years after the year of acquisition. This benefit will be returned to customers in the year the credit is 
redeemed or expired.

Common Equity. 

a.  Common Stock - MGE Energy and MGE. 

MGE Energy sells shares of its common stock through its Stock Plan. Those shares may be newly issued 
shares or shares that MGE Energy has purchased in the open market for resale to participants in the Stock 
Plan. All sales under the stock plan are covered by a shelf registration statement that MGE Energy filed with 
the SEC. For the years ended December 31, 2012 and 2011, MGE Energy did not issue any new shares of 
common stock under the Stock Plan.  

In June 2009, MGE Energy switched from issuing new shares of common stock under the Stock Plan to 
purchasing shares on the open market to provide shares to meet obligations to participants in the Stock Plan. 
The shares are purchased on the open market through a securities broker-dealer and then are reissued under 
the Stock Plan as needed to meet share delivery requirements. The volume and timing of share repurchases 
in the open market depends upon the level of dividend reinvestment and optional share purchases being 
made from time to time by plan participants. As a result, there is no specific maximum number of shares to 
be repurchased and no specified termination date for the repurchases.  

During the years ended December 31, 2012 and 2011, MGE Energy paid $36.0 million (or $1.56 per share) 
and $35.0 million (or $1.52 per share), respectively, in cash dividends on its common stock. Dividends on 
common stock at MGE are subject to restrictions imposed by the PSCW and the covenants of MGE's 
outstanding first mortgage bonds. See Footnote 9 for further discussion of these covenants. During the years 
ended December 31, 2012 and 2011, MGE paid $20.4 million and $26.6 million, respectively, in cash 
dividends to MGE Energy.

b.  Preferred Stock - MGE Energy and MGE. 

MGE had 1,175,000 shares of $25 par value cumulative preferred stock that is authorized but unissued at 
December 31, 2011. In October 2012, MGE amended and restated its existing Restated Articles of 
Incorporation, which eliminated the previously authorized cumulative preferred stock. There were no shares 
of cumulative preferred stock authorized, issued, or outstanding at December 31, 2012. 

c.  Dilutive Shares Calculation - MGE Energy. 

MGE Energy does not hold any dilutive securities.

(a)  MGE Power Elm Road and MGE Power West Campus are not subsidiaries of MGE; however, they have 

been consolidated in the consolidated financial statements of MGE (see Footnote 2). MGE Power Elm Road 
and MGE Power West Campus are 100% owned by MGE Power, and MGE Power is 100% owned by 
MGE Energy. MGE Energy's proportionate share of the equity and net income (through its wholly owned 
subsidiary MGE Power) of MGE Power Elm Road and MGE Power West Campus is classified within the 
MGE financial statements as noncontrolling interest. 

(b)  At December 31, 2012, MGE is the majority owner, and MGE Energy is the minority owner, of MGE 
Transco. MGE Energy's proportionate share of the equity and net income of MGE Transco is classified 
within the MGE financial statements as noncontrolling interest.

(a)  MGE's utility plant is subject to the lien of its Indenture of Mortgage and Deed of Trust, under which its 

first mortgage bonds are issued. The Mortgage Indenture provides that dividends or any other 
distribution or purchase of shares may not be made if the aggregate amount thereof since December 31, 
1945 would exceed the earned surplus (retained earnings) accumulated subsequent to December 31, 
1945. As of December 31, 2012, approximately $281.6 million was available for the payment of 
dividends under this covenant. 

(b)  On April 2, 2012, $19.3 million of 4.875% Series 2002B, Industrial Development Revenue Bonds were 
remarketed at an interest rate of 3.45%. The net proceeds of the 4.875% Series 2002B Bonds were 
originally loaned to MGE pursuant to a Loan Agreement dated as of April 1, 2002 with the City of 
Madison, which issued the Series 2002B Bonds in 2002. MGE is responsible for the payment of 
principal, premium, if any, and interest on the Bonds. The 4.875% Series 2002B Bonds were originally 
issued bearing an interest rate of 4.875% per annum for a period that ended April 1, 2012, at which point 
the Bonds were subject to mandatory tender by their holders and remarketing. The Series 2002B Bonds 
were remarketed and carry an interest rate of 3.45% per annum, which is payable semi-annually on 
April 1 and October 1, until their maturity on October 1, 2027. The Series 2002B Bonds are redeemable 
on or after April 1, 2017, at a redemption price equal to 100% of the principal amount of the Bonds to 
be redeemed, plus accrued interest to the redemption date.

(c)  On April 2, 2012, MGE issued $28 million in principal amount of its 4.38% senior notes, due April 1, 

2042. The Notes were issued pursuant to a Note Purchase Agreement. The Notes are unsecured and are 
not issued under, or governed by, MGE's Indenture dated as of September 1, 1998, which governs 
MGE's Medium-Term Notes. MGE used the net proceeds from the sale of the Notes, together with other 
available corporate funds, to repay and retire on April 3, 2012, its obligations under a Loan Agreement 
dated as of April 1, 2002 with the City of Madison, Wisconsin, under which MGE received the net 
proceeds from the issuance of $28 million aggregate principal amount of 5.875% Series 2002A, 
Industrial Development Revenue Bonds that were issued by the City of Madison for MGE's benefit. The 
5.875% Series 2002A Bonds were redeemed and retired on April 3, 2012, at 100% of their principal 
amount plus accrued interest with the proceeds of that loan repayment. Any interest savings in 2012 will 
be deferred. 

(d)  The indenture under which MGE's Medium-Term notes are issued provides that those notes will be 
entitled to be equally and ratably secured in the event that MGE issues any additional first mortgage 
bonds. 

(e)  Issued by MGE pursuant to a Note Purchase Agreement. Under that Note Purchase Agreement: (i) note 

holders have the right to require MGE to repurchase their notes at par in the event of an acquisition of 
beneficial ownership of 30% or more of the outstanding voting stock of MGE Energy, (ii) MGE must 
maintain a ratio of its consolidated indebtedness to consolidated total capitalization not to exceed a 
maximum of 65%, and (iii) MGE cannot issue "Priority Debt" in an amount exceeding 20% of its 
consolidated assets. Priority Debt is defined as any indebtedness of MGE secured by liens other than 
specified liens permitted by the Note Purchase Agreement and certain unsecured indebtedness of certain 
subsidiaries. As of December 31, 2012, MGE is in compliance with the covenant requirements. 

(f)  Issued by MGE Power West Campus. The agreements require it to maintain a projected debt service 

coverage ratio of not less than 1.25 to 1.00, and debt to total capitalization ratio of not more than .65 to 
1.00. The notes are secured by a collateral assignment of lease payments that MGE is making to MGE 
Power West Campus for use of its ownership interest in the West Campus Cogeneration Facility 
pursuant to a long-term lease. As of December 31, 2012, MGE Power West Campus is in compliance 
with the covenant requirements. 

(g)  Issued by MGE Power Elm Road pursuant to a Note Purchase Agreement. The Note Purchase 

Agreement requires MGE Power Elm Road to maintain a projected and actual debt service coverage 
ratio at the end of any calendar quarter of not less than 1.25 to 1.00 for the trailing 12-month period. The 
notes are secured by a collateral assignment of lease payments that MGE is making to MGE Power Elm 
Road for use of its ownership interest in the Elm Road Units pursuant to long-term leases. As of 
December 31, 2012, MGE Power Elm Road is in compliance with the covenant requirements.

10.  Notes Payable to Banks, Commercial Paper, and Lines of Credit. 

a.  MGE Energy. 

At December 31, 2012, MGE Energy had an unsecured, committed revolving line of credit of $40.0 million 
expiring July 31, 2015. At December 31, 2012, no borrowings were outstanding under this facility. 

The agreement requires MGE Energy to maintain a ratio of its consolidated indebtedness to consolidated 
total capitalization not to exceed a maximum of 65%. A change in control constitutes a default under the 
agreement. Change in control events are defined as (i) a failure by MGE Energy to hold 100% of the 
outstanding voting equity interest in MGE or (ii) the acquisition of beneficial ownership of 30% or more of 
the outstanding voting stock of MGE Energy by one person or two or more persons acting in concert. As of 
December 31, 2012, MGE Energy is in compliance with the covenant requirements. 

b.  MGE. 

For short-term borrowings, MGE generally issues commercial paper (issued at the prevailing discount rate at 
the time of issuance), which is supported by unused committed bank lines of credit. At December 31, 2012, 
MGE had an unsecured, committed revolving line of credit for $75.0 million expiring July 31, 2015. On 
August 27, 2010, MGE entered into an amendment that requires MGE to have a period of at least one day, 
during any 365-day period, on which the principal amount of all outstanding loans thereunder shall be zero. 
At December 31, 2012, no borrowings were outstanding under this facility.  

The agreement requires MGE to maintain a ratio of consolidated debt to consolidated total capitalization not 
to exceed a maximum of 65%. The ratio calculation excludes assets, liabilities, revenues, and expenses 
included in MGE's financial statements as the result of the consolidation of VIEs, such as MGE Power West 
Campus and MGE Power Elm Road. A change in control constitutes a default under the agreement. Change 
in control events are defined as (i) a failure by MGE Energy to hold 100% of the outstanding voting equity 
interest in MGE or (ii) the acquisition of beneficial ownership of 30% or more of the outstanding voting 
stock of MGE Energy by one person or two or more persons acting in concert. As of December 31, 2012, 
MGE is in compliance with the covenant requirements.

11.  Fair Value of Financial Instruments - MGE Energy and MGE. 

Fair value is defined as the price that would be received to sell an asset or would be paid to transfer a liability (an 
exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between 
market participants at the measurement date. The standard clarifies that fair value should be based on the 
assumptions market participants would use when pricing the asset or liability including assumptions about risk. 
The standard also establishes a three level fair value hierarchy based upon the observability of the assumptions 
used and requires the use of observable market data when available. The levels are: 

Level 1 - Pricing inputs are quoted prices within active markets for identical assets or liabilities. 

Level 2 - Pricing inputs are quoted prices within active markets for similar assets or liabilities; quoted prices 
for identical or similar instruments in markets that are not active; and model-derived valuations that are 
correlated with or otherwise verifiable by observable market data. 

Level 3 - Pricing inputs are unobservable and reflect management's best estimate of what market participants 
would use in pricing the asset or liability. 

a.  Fair Value of Financial Assets and Liabilities Recorded at the Carrying Amount. 

At December 31, 2012 and 2011, the carrying amount of cash and cash equivalents approximates fair market 
value due to the short maturity of those investments and obligations. The estimated fair market value of 
MGE Energy's and MGE long-term debt is based on quoted market prices for similar financial instruments at 
December 31. Since long-term debt is not traded in an active market, it is classified as Level 2. The 
estimated fair market value of MGE Energy's and MGE's financial instruments are as follows:

        (a)  These amounts are shown gross and exclude $3.0 million of collateral that was posted
               against derivative positions with counterparties. 

No transfers were made in or out of Level 1 or Level 2 for the year ended December 31, 2012. 

Investments include exchange-traded investment securities valued using quoted prices on active exchanges 
and are therefore classified as Level 1.

Derivatives include exchange-traded derivative contracts, over-the-counter transactions, a ten-year 
purchased power agreement, and FTRs. Most exchange-traded derivative contracts are valued based on 
unadjusted quoted prices in active markets and are therefore classified as Level 1. A small number of 
exchange-traded derivative contracts are valued using quoted market pricing in markets with insufficient 
volumes and are therefore classified as Level 3. Transactions done with an over-the-counter party are on 
inactive markets and are therefore classified as Level 3. These transactions are valued based on quoted prices 
from markets with similar exchange traded transactions. FTRs are priced based upon monthly auction results 
for identical or similar instruments in a closed market with limited data available and are therefore classified 
as Level 3.  

The ten-year purchased power agreement (see Footnote 16) was valued using an internally-developed 
pricing model and therefore is classified as Level 3. The model projects future market energy prices and 
compares those prices to the projected power costs to be incurred under the contract. Inputs to the model 
require significant management judgment and estimation. Future energy prices are based on a forward power 
pricing curve using exchange-traded contracts in the electric futures market, where such exchange-traded 
contracts exist, and upon calculations based on forward gas prices, where such exchange-traded contracts do 
not exist. A basis adjustment is applied to the market energy price to reflect the price differential between the 
market price delivery point and the counterparty delivery point. The historical relationship between the 
delivery points is reviewed and a discount (below 100%) or premium (above 100%) is derived. This 
comparison is done for both peak times when demand is high and off peak times when demand is low. If the 
basis adjustment is lowered, the fair value measurement will decrease and if the basis adjustment is 
increased, the fair value measurement will increase. 

The projected power costs anticipated to be incurred under the purchased power agreement are determined 
using many factors, including historical generating costs, future prices, and expected fuel mix of the 
counterparty. An increase in the projected fuel costs would result in a decrease in the fair value measurement 
of the purchased power agreement. A significant input that MGE estimates is the counterparty's fuel mix in 
determining the projected power cost. MGE also considers the assumptions that market participants would 
use in valuing the asset or liability. This consideration includes assumptions about market risk such as 
liquidity, volatility, and contract duration. The fair value model uses a discount rate that incorporates 
discounting, credit, and model risks. 

This model is prepared by members of MGE's Energy Supply group. It is reviewed on a quarterly basis by 
management in Energy Supply and Finance to review the assumptions, inputs, and fair value measurements. 

The following table presents the significant unobservable inputs used in the pricing model.

    On peak ...........................................................

The deferred compensation plan allows participants to defer certain cash compensation into a notional 
investment account. These amounts are included within other deferred liabilities in the consolidated balance 
sheets of MGE Energy and MGE. The notional investments earn interest based upon the semiannual rate of 
U.S. Treasury Bills having a 26 week maturity increased by 1% compounded monthly with a minimum 
annual rate of 7%, compounded monthly. The notional investments are based upon observable market data, 
however since the deferred compensation obligations themselves are not exchanged in an active market they 
are classified as Level 2.

(b)  MGE's exchange-traded derivative contracts, over-the-counter party transactions, ten-year 

purchased power agreement, and FTRs are subject to regulatory deferral. These derivatives are 
therefore marked to fair value and are offset with a corresponding regulatory asset or liability. A 
portion of MGE's derivative contracts fall under the incentive mechanism within the PGA clause 
and, prior to 2011, shareholders had the ability to receive a set percentage of the benefit or loss 
from these deals if certain thresholds were achieved. Under these derivatives, only the gains or 
losses associated with customers are subject to regulatory deferral. The remaining shareholder 
portion is reflected in other comprehensive income. As a result of the above described treatment, 
there are no unrealized gains or losses that flow through earnings.

Income Taxes. 

a.  MGE Energy and MGE Income Taxes. 

MGE Energy files a consolidated federal income tax return that includes the operations of all subsidiary 
companies. The subsidiaries calculate their respective federal income tax provisions as if they were separate 
taxable entities.  

On a consolidated and separate company basis, MGE Energy's and MGE's income tax provision consists of 
the following provision (benefit) components for the years ended December 31:

As of December 31, 2012, MGE Energy had approximately $63.4 million and $3.4 million of net operating 
loss and tax credit carryforwards, respectively. The net operating loss and tax credit carryforwards resulted 
in deferred tax assets of $22.2 million and $3.4 million, respectively, as of December 31, 2012.  

As of December 31, 2012, MGE had approximately $64.2 million and $3.4 million of net operating loss and 
tax credit carryforwards, respectively. The net operating loss and tax credit carryforwards resulted in 
deferred tax assets of $22.5 million and $3.4 million, respectively, as of December 31, 2012. 

The net operating loss carryforwards and tax credit carryforwards begin to expire in 2031. Both 
MGE Energy and MGE anticipate having future taxable income sufficient to utilize these deferred tax assets. 

The valuation allowance reduces MGE Energy's and MGE's deferred tax assets for state carryforward losses 
to estimated realizable value due to the uncertainty of future income estimates in various state tax 
jurisdictions. 

For tax purposes, as of December 31, 2012, both MGE Energy and MGE had approximately $7.5 million of 
state tax net operating loss deductions that expire between 2013 and 2023 if unused.

b.  Accounting for Uncertainty in Income Taxes - MGE Energy and MGE. 

MGE Energy and MGE account for the difference between the tax benefit amount taken on prior year tax 
returns, or expected to be taken on a current year tax return, and the tax benefit amount recognized in the 
financial statements as an unrecognized tax benefit.  

A tabular reconciliation of unrecognized tax benefits and interest from January 1, 2010, to December 31, 
2012, is as follows:

Unrecognized tax benefits are liabilities shown with Other Deferred Liabilities on the December 31, 2012, 
and December 31, 2011, consolidated balance sheets. The interest component is offset by a regulatory asset. 

MGE Energy filed an application with its 2009 tax returns to change its income tax methods of accounting 
for electric generation, transmission and distribution repairs and its 2010 tax returns for gas distribution 
repairs. These method changes accelerated tax deductions for repairs in accordance with Treasury 
Regulations and case law, as compared to the prior method of claiming tax depreciation on project costs. 
During 2011, the IRS issued guidance on the treatment of electric transmission and distribution repairs. This 
guidance has prompted the reversal of a majority of the unrecognized tax benefits for these repairs. At 
December 31, 2012, MGE Energy and MGE have an unrecognized tax benefit in the amount of $3.2 million 
related to temporary tax differences associated with the change in income tax method of accounting for 
electric generation, transmission and distribution repairs and gas distribution repairs. At December 31, 2011, 
unrecognized tax benefits in the amount of $2.4 million primarily related to temporary tax differences 
associated with the change in income tax method of accounting for electric generation repairs, and gas 
distribution repairs. There were no unrecognized tax benefits at December 31, 2012, related to federal 
permanent differences and tax credits. Unrecognized tax benefits at December 31, 2011, related to federal 
permanent differences and tax credits was $0.2 million. 

The unrecognized tax benefits at December 31, 2012, are not expected to significantly increase or decrease 
within the next twelve months. However, the IRS may issue guidance on the treatment of electric generation 
and/or gas distribution repairs. In addition, statutes of limitations will expire for MGE Energy and MGE tax 
returns. The impact of the statutes of limitations expiring is not anticipated to be material. Due to the filing 
of an amended return and subsequent examination, the 2007 federal and Wisconsin returns remains open. 
The following table shows tax years that remain subject to examination by major jurisdiction:

c.  Medicare Part D Subsidy - MGE Energy and MGE. 

In March 2010, the Patient Protection and Affordable Care Act (the PPACA) was enacted. The PPACA 
effectively changes the tax treatment of federal subsidies paid to sponsors of retiree health benefit plans that 
provide a benefit that is at least actuarially equivalent to the benefits under Medicare Part D. As a result of 
the PPACA, these subsidy payments will become taxable in tax years beginning after December 31, 2012. In 
connection with accounting for Income Taxes, companies are required to reflect the impact of the change in 
tax law in the period that includes the enactment date of March 23, 2010. MGE anticipates recovery in rates 
of the incremental tax expense as a result of the legislation. In 2012, MGE specifically identified amounts 
within the retiree health benefit plans to be used for payment of future health insurance premiums, reducing 
the amount that MGE anticipates recovering in rates.  

13.  Pension Plans and Other Postretirement Benefits - MGE Energy and MGE. 

MGE maintains qualified and nonqualified pension plans, health care, and life insurance benefits, and two 
defined contribution 401(k) benefit plans for its employees and retirees. MGE's costs for the 401(k) plans were 
$2.1 million, $1.8 million, and $1.6 million in 2012, 2011, and 2010, respectively. A measurement date of 
December 31 is utilized for all pension and postretirement benefit plans. 

All employees hired after December 31, 2006, have been enrolled in the defined contribution pension plan, rather 
than the defined benefit pension plan previously in place.

The expected long-term rate of return on the pension plan assets is 8.10% and 8.25% for 2012 and 2011, 
respectively. In 2013, the return on asset assumption will remain at 8.10%. 

c.  Explanation of Long-Term Rate of Return. 

MGE employs a building-block approach in determining the expected long-term rate of return for asset 
classes. Historical markets are studied and long-term historical relationships among asset classes are 
analyzed, consistent with the widely accepted capital market principle that assets with higher volatility 
generate a greater return over the long run. Current market factors, such as interest rates and dividend yields, 
are evaluated before long-term capital market assumptions are determined. 

The expected long-term nominal rate of return for plan assets is primarily a function of expected long-term 
real rates of return for component asset classes and the plan's target asset allocation in conjunction with an 
inflation assumption. Peer data and historical returns are reviewed to check for appropriateness. 

The asset allocation for MGE's pension plans at the end of 2012 and 2011, and the target allocation for 2013, 
by asset category, follows: 

Equity securities..................................

d.  Investment Strategy. 

MGE employs a total return investment approach whereby a mix of equities, fixed income, and real estate 
investments are used to maximize the expected long-term return of plan assets for a prudent level of risk. 
Risk tolerance is established through careful consideration of plan liabilities, plan-funded status, and 
corporate financial condition. The investment portfolio contains a diversified blend of equity, fixed income, 
and real estate investments. Target asset allocations are as follows: 45.5% United States equity, 17.5% non-
United States equity, 30.0% fixed income, and 7.0% real estate. Investment risk is measured and monitored 
on an ongoing basis through periodic investment portfolio reviews and liability measurements.

e.  Concentrations of Credit Risk. 

  MGE evaluated its pension and other postretirement benefit plans' asset portfolios for the existence of 

significant concentrations of credit risk as of December 31, 2012. Types of concentrations that were 
evaluated include, but are not limited to, investment concentrations in a single entity, type of industry, and 
foreign country. As of December 31, 2012, there were no significant concentrations (defined as greater than 
10 percent of plan assets) of risk in MGE pension and postretirement benefit plan assets. 

f.   Fair Value Measurements of Plan Assets. 

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit 
price) in the principal or most advantageous market for the asset or liability in an orderly transaction between 
market participants at the measurement date. The standard clarifies that fair value should be based on the 
assumptions market participants would use when pricing the asset or liability including assumptions about 
risk. The standard also establishes a three level fair value hierarchy based upon the observability of the 
assumptions used and requires the use of observable market data when available. The levels are: 

Level 1 - Pricing inputs are quoted prices within active markets for identical assets or liabilities. 

Level 2 - Pricing inputs are quoted prices within active markets for similar assets or liabilities; quoted 
prices for identical or similar instruments in markets that are not active; and model-derived valuations 
that are correlated with or otherwise verifiable by observable market data. 

Level 3 - Pricing inputs are unobservable and reflect management's best estimate of what market 
participants would use in pricing the asset or liability. 

The following is a description of the valuation methodologies used for assets measured at fair value as of 
December 31, 2012: 

Cash and Cash Equivalents – This category includes highly liquid investments with maturities of less than 
three months which are traded in active markets. 

Equity Securities – These securities consist of U.S. and international stock funds. The U.S. stock funds are 
primarily invested in domestic equities. Securities in these funds are typically priced using the closing price 
from the applicable exchange, NYSE, NASDAQ, etc. The international funds are composed of international 
equities. Securities are priced using the closing price from the appropriate local stock exchange. 

Fixed Income Securities – These securities consist of U.S. bond funds and short-term funds. U.S. bond funds 
are priced by a pricing agent using inputs such as benchmark yields, reported trades, broker/dealer quotes, 
and issuer spreads. The short-term funds are valued initially at cost and adjusted for amortization of any 
discount or premium. 

Real Estate – The fair value of real estate properties is determined through an external appraisal process.  

Insurance Continuance Fund (ICF) – The fair value of the ICF is based on largely unobservable inputs, 
which are based on a commingled interest.

g.   Other Postretirement Benefits. 

The fair value of plan assets for the postretirement benefit plans is $32.1 million and $23.5 million at the end 
of 2012 and 2011, respectively. The expected long-term rate of return on these plan assets is 7.26% and 
7.39% for 2012 and 2011, respectively. In 2013, MGE will lower the return on asset assumption from 7.26% 
to 6.79%. 

Of the above amounts, $25.0 million and $20.1 million at the end of 2012 and 2011, respectively, were held 
in the master pension trust and are allocable to postretirement health expenses. The target asset allocation 
and investment strategy for the portion of assets held in the master pension trust are the same as that 
explained for MGE's pension plans. 

The remainder of postretirement benefit assets are held either in an insurance continuance fund for the 
payment of retiree life benefits or a health benefit trust for payment of retiree health claims. There is no 
formal target asset allocation for these assets, but the intent is to seek interest income and maintain stability 
of principal.

i.  Expected Cash Flows. 

Contributions to the plans for 2013 are expected to be approximately $32 million, of which $30 million was 
paid in January 2013. For 2014 and 2015, contributions are expected to be between $11 million to 
$13 million each year. The contributions for years after 2015 are not yet currently estimated. MGE has 
adopted the asset smoothing as permitted in accordance with the Pension Protection Act of 2006, including 
modifications made by WRERA. 

Due to uncertainties in the future economic performance of plan assets, discount rates, and other key 
assumptions, estimated contributions are subject to change. MGE may also elect to make additional 
discretionary contributions. 

In 2012, MGE made $28.9 million in employer contributions to its pension and postretirement plans.

The PSCW has allowed MGE to defer the 2009 incremental pension and OPRB costs above the amounts 
recovered in rates. During the years ended December 31, 2012 and 2011, $1.2 million and $2.6 million, 
respectively, has been recovered in rates.  

14. 

Share-Based Compensation - MGE Energy and MGE. 

Under MGE Energy's Performance Unit Plan, eligible participants may receive performance units that entitle the 
holder to receive a cash payment equal to the value of a designated number of shares of MGE Energy's common 
stock, plus dividend equivalent payments thereon, at the end of the set performance period. In accordance with 
the plan's provisions, these awards are subject to a prescribed vesting schedule and must be settled in cash. 
Accordingly, no shares of common stock will be issued in connection with the plan.  

On the grant date, MGE Energy and MGE measure the cost of the employee services received in exchange for a 
performance unit award based on the current market value of MGE Energy common stock. The fair value of the 
awards is re-measured quarterly, including at December 31, 2012, as required by applicable accounting 
standards. Changes in fair value as well as the original grant are recognized as compensation cost. Since this 
amount is re-measured throughout the vesting period, the compensation cost is subject to variability. These units 
are subject to a five year graded vesting schedule.

For nonretirement eligible employees, stock based compensation costs are accrued and recognized using the 
graded vesting method. Compensation cost for retirement eligible employees or employees that will become 
retirement eligible during the vesting schedule are recognized on an abridged horizon. 

In April 2011, the MGE Energy Board approved an amendment to the outstanding awards under the Performance 
Unit Plan to provide for the continued vesting of those awards in the event of a bona fide retirement, provided the 
retired individual does not provide services to a competitor. The amendment did not change the number of 
performance units covered by any outstanding awards then held by any of the participants.  

As a result of the changes made by the amendment, MGE accelerated the recognition of costs associated with the 
outstanding awards resulting in a compensation-related charge of $0.5 million in the second quarter of 2011. 

During both the years ended December 31, 2012 and 2011, MGE recorded $1.4 million in compensation expense 
as a result of awards under the Performance Unit Plan. Compensation expense during the year ended 
December 31, 2010, was $1.2 million. In January 2012, cash payments of $0.6 million were distributed relating 
to awards that were granted in 2007 and became payable under the Performance Unit Plan. No forfeitures 
occurred during the years ended December 31, 2012, 2011, and 2010. At December 31, 2012, $4.0 million of 
outstanding awards are vested, of this amount no cash settlements have occurred. 

15.  Regional Transmission Organizations - MGE Energy and MGE. 

MISO 
MGE is a nontransmission owning member of the MISO. MISO, a FERC approved RTO, is responsible for 
monitoring the electric transmission system that delivers power from generating plants to wholesale power 
transmitters. MISO's role is to ensure equal access to the transmission system and to maintain or improve electric 
system reliability in the Midwest. 

MISO maintains a bid-based energy market. MGE offers substantially all of its generation on the MISO market 
and purchases much of its load requirement from the MISO market in accordance with the MISO Tariff. MGE 
participates in the ancillary services market (ASM) operated by MISO. The ASM is an extension of the existing 
energy market in which MISO assumes the responsibility of maintaining sufficient generation reserves. In the 
ASM, MISO provides the reserves for MGE's load, and MGE may offer to sell reserves from its generating units.

MGE participates in the voluntary capacity auction, which provides an optional monthly forum for buyers and 
sellers of aggregate planning resource credits to interact. Load serving entities may participate in the voluntary 
capacity auction potentially to obtain the necessary aggregate planning resource credits needed to meet their 
planning reserve margin requirement. Generator owners may participate to sell any excess aggregate planning 
resource credits that are not needed by them.  

PJM  
MGE is a member of PJM. PJM, an RTO, is a neutral and independent party that coordinates and directs the 
operation of the transmission grid within its area of coverage, administers a competitive wholesale electricity 
market, and plans regional transmission expansion improvements to maintain grid reliability and relieve 
congestion. 

MGE reports on a net basis transactions on the MISO and PJM markets in which it buys and sells power within 
the same hour to meet electric energy delivery requirements. This treatment resulted in a $75.9 million, 
$102.1 million, and $94.9 million reduction to sales to the market and purchased power expense for the years 
ended December 31, 2012, 2011, and 2010, respectively. 

16.  Derivative and Hedging Instruments - MGE Energy and MGE. 

a.  Purpose. 

As part of its regular operations, MGE enters into contracts, including options, swaps, futures, forwards, and 
other contractual commitments, to manage its exposure to commodity prices and gas revenues. To the extent 
that these contracts are derivatives, MGE assesses whether or not the normal purchases or normal sales 
exclusion applies. For contracts to which this exclusion cannot be applied, MGE Energy and MGE recognize 
such derivatives in the consolidated balance sheets at fair value. The majority of MGE's derivative activities 
are conducted in accordance with its electric and gas risk management program, which is approved by the 
PSCW and limits the volume MGE can hedge with specific risk management strategies. The maximum 
length of time over which cash flows related to energy commodities can be hedged is four years. If the 
derivative qualifies for regulatory deferral, the derivatives are marked to fair value and are offset with a 
corresponding regulatory asset or liability. The deferred gain or loss is recognized in earnings in the delivery 
month applicable to the instrument. Gains and losses related to hedges qualifying for regulatory treatment 
are recoverable in gas rates through the PGA or in electric rates as a component of the fuel rules mechanism.  

b.  Notional Amounts. 

The gross notional volume of open derivatives is as follows:

FTRs .......................................................................

444,650 MWh 
1,980,000 Dth

4,030,000 Dth 
2,382 MW 

December 31, 2012  

December 31, 2011  

c.  Financial Statement Presentation. 

MGE Energy and MGE offset fair value amounts recognized for the right to reclaim collateral (a receivable) 
or the obligation to return collateral (a payable) against fair value amounts recognized for derivative 
instruments executed with the same counterparty under a master netting agreement. At December 31, 2012, 
MGE Energy and MGE had no collateral that was netted against the net derivative positions with 
counterparties. At December 31, 2011, MGE Energy and MGE had $3.0 million in collateral that was netted 
against the net derivative positions with counterparties.  

MGE purchases and sells exchange-traded and over-the-counter options, swaps, and future contracts. These 
arrangements are primarily entered into to help stabilize the price risk associated with gas or power 
purchases. These transactions are employed by both MGE's gas and electric segments. Additionally, as a 
result of the firm transmission agreements that MGE holds on transmission paths in the MISO market, MGE 
holds FTRs. An FTR is a financial instrument that entitles the holder to a stream of revenues or charges 
based on the differences in hourly day-ahead energy prices between two points on the transmission grid. The 
fair values of these instruments are reflected as a regulatory asset/liability depending on whether they are in a 
net loss/gain position. Depending on the nature of the instrument, the gain or loss associated with these  

88 

 
 
 
 
 
 
 
 
 
 
 
 
  
  
  
 
  
  
 
  
  
 
  
  
 
 
 
 
transactions will be reflected as cost of gas sold, fuel for electric generation, or purchased power expense in 
the delivery month applicable to the instrument. At December 31, 2012, the fair value of exchange traded 
derivatives and FTRs exceeded their cost basis by $0.3 million. At December 31, 2011, the cost basis of 
exchange traded derivatives and FTRs exceeded their fair value by $2.8 million. 

MGE is a party to a ten-year purchased power agreement that provides MGE with firm capacity and energy 
during a base term from June 1, 2012, through May 31, 2022. The agreement also allows MGE an option to 
extend the contract after the base term. The agreement is accounted for as a derivative contract and is 
recognized at its fair value on the consolidated balance sheet. However, the derivative qualifies for 
regulatory deferral and is recognized with a corresponding regulatory asset or liability depending on whether 
the fair value is in a loss or gain position. The fair value of the contract at December 31, 2012 and 2011, 
reflects a loss position of $72.6 million and $39.5 million, respectively. The actual fuel cost will be 
recognized in purchased power expense in the month of purchase. 

The following table summarizes the fair value of the derivative instruments on the consolidated balance 
sheet. All derivative instruments in this table are presented on a gross basis and are calculated prior to the 
netting of instruments with the same counterparty under a master netting agreement as well as the netting of 
collateral. For financial statement purposes, MGE Energy and MGE have netted instruments with the same 
counterparty under a master netting agreement as well as the netting of collateral.

(a)  MGE's commodity derivative contracts, FTRs, and ten-year PPA are subject to regulatory deferral. 

These derivatives are marked to fair value and are offset with a corresponding regulatory asset or 
liability. Realized gains and losses are deferred on the consolidated balance sheet and are recognized 
in earnings in the delivery month applicable to the instrument. As a result of the above described 
treatment, there are no unrealized gains or losses that flow through earnings.  

The ten-year PPA has a provision that may require MGE to post collateral if MGE's debt rating falls below 
investment grade (i.e., below BBB-) once MGE begins purchasing energy under the contract in 2012. The 
amount of collateral that it may be required to post varies from $20.0 million to $40.0 million, depending on 
MGE's nominated capacity amount. As of December 31, 2012, no collateral has been posted. Certain 
counterparties extend MGE a credit limit. If MGE exceeds these limits, the counterparties may require 
collateral to be posted. As of December 31, 2012 and 2011, no counterparties are in a net liability position.  

Nonperformance of counterparties to the non-exchange traded derivatives could expose MGE to credit loss. 
However, MGE enters into transactions only with companies that meet or exceed strict credit guidelines, and 
it monitors these counterparties on an ongoing basis to mitigate nonperformance risk in its portfolio. As of 
December 31, 2012, no counterparties have defaulted. 

17.  Rate Matters - MGE Energy and MGE. 

a.  Rate Proceedings. 

On December 14, 2012, the PSCW authorized MGE to increase 2013 rates for retail electric customers by 
3.8% or $14.9 million and to increase gas rates by 1.0% or $1.6 million. The change in retail electric rates 
was driven by costs for new environmental equipment at Columbia, final construction costs for the Elm 
Road Units, transmission reliability enhancements, and purchased power costs. The authorized return on 
common stock equity remains unchanged at 10.3%. 

On December 15, 2011, under a limited reopener of MGE's last rate order, the PSCW authorized MGE to 
increase 2012 rates for retail electric customers by 4.3% or $15.7 million and to increase gas rates by 0.3% 
or $0.6 million. The change in retail electric rates was driven by MGE's electric fuel and purchased power 
costs, increased transmission costs, an update to the Elm Road Units' costs, and an increase for energy 
efficiency programs. The PSCW also approved deferral of CSAPR costs. 

On January 12, 2011, the PSCW authorized MGE to increase 2011 rates for retail electric customers by 2.3% 
or $8.0 million and to increase gas rates by 1.0% or $1.9 million. The increase in retail electric rates was 
driven by costs for MGE's share of the Elm Road Units. Pursuant to the provisions of this rate order, the fuel 
rules bandwidth effective January 1, 2011, will be plus or minus 2%. Authorized return on common stock 
equity was set at 10.3% based on a 58.1% utility common equity.

On December 22, 2009, the PSCW authorized MGE to increase 2010 rates for retail electric customers by 
3.3% or $11.9 million, while gas rates decreased 0.74% or $1.5 million. The increase in retail electric rates 
was driven by costs for MGE's share of the Elm Road Units and transmission reliability enhancements. 
Pursuant to the provisions of this rate order, the fuel rules bandwidth effective January 1, 2010, was plus or 
minus 2%. Authorized return on common stock equity was set at 10.4% based on a 55.3% utility common 
equity.  

b.  Fuel Rules. 

The PSCW approved new fuel rules that became effective January 1, 2011. The new rules require the PSCW 
and Wisconsin utilities to defer electric fuel-related costs that fall outside a symmetrical cost tolerance band 
around the amount approved for a utility in its most recent base rate proceedings. Any over/under recovery 
of the actual costs is determined on an annual basis and will be adjusted in future billings to electric retail 
customers. The fuel rules bandwidth is currently set at plus or minus 2%. Under fuel rules, MGE would defer 
costs, less any excess revenues, if its actual electric fuel costs exceed 102% of the electric fuel costs allowed 
in its latest rate order. Excess revenues are defined as revenues in the year in question that provide MGE 
with a greater return on common equity than authorized by the PSCW in MGE's latest rate order. 
Conversely, MGE is required to defer the benefit of lower costs if actual electric fuel costs are less than 98% 
of the electric fuel costs allowed in that order.  

As of December 31, 2012, MGE has deferred $6.2 million (to be returned to customers in a future period) of 
electric fuel-related savings that are outside the range authorized by the PSCW. In 2010, a refund of 
$0.3 million of over collected 2009 fuel costs was refunded to customers on their April 2010 bills. 

18.  Commitments and Contingencies. 

a.  Purchase Contracts - MGE Energy and MGE. 

MGE Energy and MGE have entered into various commodity supply, transportation and storage contracts to 
meet their obligations to deliver electricity and natural gas to customers. As of December 31, 2012, the 
future minimum commitments related to these purchase contracts were as follows:

(a)  Total coal commitments for the Columbia and Elm Road Units, including transportation. Fuel 

procurement for MGE's jointly owned Columbia and Elm Road Units are handled by WPL and WEPCO, 
respectively, who are the operators of those facilities. If any minimum purchase obligations must be paid 
under these contracts, management believes these obligations would be considered costs of service and 
recoverable in rates. 

(b)  MGE's natural gas transportation and storage contracts require fixed monthly payments for firm supply 
pipeline transportation and storage capacity. The pricing components of the fixed monthly payments for 
the transportation and storage contracts are established by FERC but may be subject to change. 

(c)  These commitments include market-based pricing. Management expects to recover these costs in future 

customer rates.

(d)  MGE has several purchase power agreements to help meet future electric supply requirements. 

Management expects to recover these costs in future customer rates. In October 2008, MGE entered into a 
ten-year purchase power agreement to help meet future electric supply requirements. Under this 
agreement, MGE has agreed to purchase 50 MW of wind power from Osceola Windpower II, LLC, which 
is located in Iowa. This facility became operational in October 2008. MGE does not have any capacity 
payment commitments under this agreement. However, MGE is obligated to purchase its ratable share of 
the energy produced by the project. MGE's commitment related to its ratable share of energy produced by 
the project has been estimated and is included in the above numbers.  

b.  Chattel Paper Agreement and Other Guarantees - MGE Energy and MGE. 

MGE makes available to qualifying customers a financing program for the purchase and installation of 
energy-related equipment that will provide more efficient use of utility service at the customer's property. 
MGE is party to a chattel paper purchase agreement with a financial institution under which it can sell or 
finance an undivided interest with recourse, in up to $10.0 million of the financing program receivables, until 
July 31, 2013. At December 31, 2012, 2011, and 2010, respectively, MGE had sold a $4.5 million, 
$4.3 million, and $3.6 million interest in these receivables. MGE retains the servicing responsibility for these 
receivables. 

MGE accounts for servicing rights under the amortization method. Initial determination of the servicing asset 
fair value is based on the present value of the estimated future cash flows. The discount rate is based on the 
PSCW authorized weighted cost of capital. 

MGE maintains responsibility for collecting and remitting loan payments from customers to the financial 
institution and does not retain any interest in the assets sold to the financial institution. At both December 31, 
2012 and 2011, MGE had recorded a servicing asset of $0.2 million. At December 31, 2010, MGE had 
recorded a servicing asset of $0.1 million. MGE recognized a gain of $0.1 million for each of the years 
ended December 31, 2012 and 2011, in connection with the sale of loan assets. MGE recognized gains of 
less than $0.1 million for the year ended December 31, 2010, in connection with the sale of loan assets. The 
servicing asset amount amortized in 2012 was less than $0.1 million. The loan assets are sold to the financial 
institution at cost, which approximates fair value in view of their market rates of interest. During 2012, 2011, 
and 2010, MGE received approximately $1.2 million, $1.5 million, and $0.5 million, respectively, from the 
financial institution for the sale of loan assets. During those same years, payments of $1.2 million, 
$0.8 million, and $0.7 million, respectively, were made by MGE to the financial institution. 

MGE would be required to perform under its guarantee if a customer defaulted on its loan. The energy-
related equipment installed at the customer sites is used to secure the customer loans. The loan balances 
outstanding at December 31, 2012, approximate the fair value of the energy-related equipment acting as 
collateral. The length of the MGE guarantee to the financial institution varies from one to ten years 
depending on the term of the underlying customer loan. Principal payments for the next five years on the 
loans are:

c.  Leases - MGE Energy and MGE. 

MGE has noncancelable operating leases, primarily for combustion turbines, railcars, and computer 
equipment. The operating leases generally do not contain renewal options, with the exception of certain 
railcar operating leases. These leases have a renewal option of one year or less. MGE is required to pay all 
executory costs such as maintenance and insurance for its leases. 

Future minimum rental payments at December 31, 2012, under agreements classified as operating leases 
with noncancelable terms in excess of one year are as follows:

d.  Smart Grid Investment Grant - MGE Energy and MGE. 

MGE was approved in 2010 by the U.S. Department of Energy (DOE) under the federal stimulus program 
for a $5.5 million grant for smart grid projects. The DOE grant requires MGE to match the grant funding, 
bringing the total cost of the projects to more than $11 million. The projects involve the installation of 
technologies to boost efficiency, enhance service, and improve reliability for customers. The stimulus grant 
is being used to fund the following projects: advanced metering infrastructure, plug-in hybrid electric 
vehicles support, and distribution management. As of December 31, 2012, MGE has spent $8.4 million 
related to these projects and has outstanding agreements to purchase $1.3 million in smart grid related 
products for 2013. 

e.  Environmental - MGE Energy and MGE. 

Water Quality 

Water quality regulations promulgated by the EPA and WDNR in accordance with the Federal Water 
Pollution Control Act, or more commonly known as the Clean Water Act (CWA), impose restrictions on 
discharges of various pollutants into surface waters. The CWA also regulates surface water quality issues 
that affect aquatic life, such as water temperatures, intake structures, and wetlands filling. The CWA also 
includes discharge standards, which require the use of effluent-treatment processes equivalent to categorical 
"best practicable" or "best available" technologies. The CWA regulates discharges from "point sources" such 
as power plants through establishing discharge limits in water discharge permits. MGE's power plants 
operate under Wisconsin Pollution Discharge Elimination System (WPDES) permits to ensure compliance 
with these discharge limits. 

The WDNR and the EPA have proposed various regulations that focus on point-source discharges. 

WDNR's Thermal and Phosphorus Emissions Standards 
In December 2010, the WDNR published new regulations for phosphorus and thermal discharges from 
electric-steam generating plants. Blount's WPDES permit was renewed, effective October 1, 2012, with 
these new thermal and phosphorus effluent discharge limits in place. We believe that the thermal and 
phosphorus limits are achievable at all of our generation plants without additional capital expenditures. We 
will continue to monitor these requirements as our other plant permits come up for renewal. 

EPA Cooling Water Intake Rules (Section 316(b)) 
Section 316(b) of the Clean Water Act requires that the cooling water intake structures at electric power 
plants meet best available technology standards so that mortality from entrainment (drawing aquatic life into 
a plant's cooling system) and impingement (trapping aquatic life on screens) are reduced. Section 316(b) is 
implemented in Wisconsin through modifications to plants' WPDES permits. Although new facilities have 
been required to meet 316(b) standards for some time, regulations for existing facilities have not yet been 
finalized. 

In April 2011, the EPA asked for public comment on proposed standards for existing facilities under 316(b). 
In June 2012, the EPA published two Notices of Data Availability (NODA) seeking public comment on 
alternate compliance technologies. The EPA has until June 27, 2013 to issue the final rule, pursuant to a 
recently announced settlement agreement.  

The currently proposed rule and potential alternatives allow for a state permitting agency's discretion in 
determining best technology available at plants that are under their permitting authority and is not requiring 
cooling towers in all instances. The WDNR holds permitting authority for Wisconsin. Both Blount and 
Columbia generating plants are subject to both the impingement and entrainment aspects of the current 
proposed rule. WCCF is subject to the impingement aspect only. We anticipate that under the current 
proposed rule, equipment would need to be installed at Blount, WCCF and Columbia to meet these new 
standards. However it is not presently possible to estimate the potential costs associated with this rule 
because the rule has not been finalized. 

Energy Efficiency and Renewables 

The Wisconsin Energy Efficiency and Renewables Act requires that, by 2015, 10% of the state's electricity 
be generated from renewable resources. MGE expects the cost to comply with the Act and its accompanying 
regulations will be recoverable through current and future rates. 

93 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Air Quality 

Federal and state air quality regulations impose restrictions on emission of particulates (PM), sulfur dioxide 
(SO2), nitrogen oxides (NOx) and other pollutants and require permits for operation of emission sources. 
These permits have been obtained by MGE and must be renewed periodically. Various initiatives, including 
interstate pollution transport rules, maximum achievable control technology (MACT) standards, new source 
performance standards (NSPS), the Clean Air Visibility Rule (also known as the Regional Haze Rule), and 
mercury emissions limits are expected to result in additional operating and capital expenditure costs for 
electric generating units. 

Vacation of EPA's Cross State Air Pollution Rule (CSAPR) and Reinstatement of the Clean Air Interstate 
Rule (CAIR) 
EPA has promulgated three interstate air pollution rules consisting of the NOx SIP Call, the Clean Air 
Interstate Rule (CAIR) and the Cross-State Air Pollution Rule (CSAPR). These rules were each designed to 
reduce nitrogen oxide (NOx) and/or sulfur dioxide (SO2) air emissions from EGUs, including EGUs located 
in Wisconsin and other states. NOx and SO2 interact in the atmosphere to form ambient ozone and fine 
particulate matter pollution. As explained below, only the CAIR currently affects MGE's generation assets.  

In 2000, the U.S. Court of Appeals for the D.C. Circuit held that Wisconsin had been illegally included in a 
portion of the NOx SIP Call, but stayed the remaining legal challenges to the rule pending EPA's 
development of additional interstate transport rules. At this time, the requirements of the NOx SIP Call and 
the costs of compliance remain uncertain.   

In 2005, EPA promulgated the CAIR imposing additional controls on NOx and SO2 emissions from EGUs, 
including EGUs located in Wisconsin. However, in December 2008, the U.S. Court of Appeals for the D.C. 
Circuit remanded the CAIR to the EPA with directions to revise or replace the rule. The Court's remand 
order directed that the CAIR remain in effect until the EPA promulgated a replacement rule. The Court's 
order did not include a deadline for the EPA to act. 

In August 2011, the EPA responded to the remand of the CAIR by promulgating the CSAPR. However, in 
August 2012, the U.S. Court of Appeals for the D.C. Circuit vacated CSAPR and instructed the EPA to 
continue administering the CAIR pending finalizing a valid alternative program to control interstate 
pollution. In January 2013, the U.S. Court of Appeals for the D.C. Circuit denied EPA's petition for 
reconsideration decision en banc. At this time, the CAIR remains currently effective. 

The CAIR, which became effective in 2009 and remains effective currently, generally requires NOx and SO2 
emission reductions from fossil fuel-fired EGUs (25 MW or greater) in the eastern half of the United States 
in two phases and includes a regional cap-and-trade system. The first phase (currently in place) requires 
annual regional emission reductions from 2003 levels of 55% for NOx and 40% for SO2. The second phase 
(beginning in 2015) reduces regional NOx and SO2 emissions further from 2003 levels to 65% and 70%, 
respectively. MGE owns or has partial ownership in several generation units currently subject to the CAIR: 
Blount, Columbia, Elm Road Units, and its combustion turbines located in West Marinette and Fitchburg.  

Our evaluation of the CAIR demonstrates that MGE will be in compliance with the CAIR's Phase I 
requirements without capital expenditures or modifications to our operations. We have also evaluated our 
potential expenditures if the CAIR remains in place for the Phase II reductions. Based on our Phase II 
evaluation, MGE will be able to meet Phase II NOx emissions reductions through using our NOx allowances 
provided through the rule, and we will meet Phase II SO2 emissions reductions through installation of 
pollution controls. New SO2 controls at Columbia are already underway and are planned to be completed by 
early 2014 (see the discussion regarding the Columbia environmental project below). Once the new 
environmental control project is completed at Columbia, it is expected that the plant will emit SO2 below 
anticipated Phase II CAIR allocation levels. MGE expects that any costs incurred to meet Phase II of the 
CAIR will be fully recoverable through rates. MGE will continue monitoring the EPA's actions in response 
to the August 2012 CSAPR vacature, and the stayed NOx SIP Call litigation. 

Clean Air Visibility Rule (CAVR) 
Air modeling indicates that SO2 and NOx emissions (and to a lesser extent particulate matter, or PM) from 
Columbia may impair visibility at certain Class I Scenic Areas and may therefore be subject to the best 
available retrofit technology (BART) regulations, a subsection of the EPA's Clean Air Visibility Rule 
(CAVR), which may require pollution retrofits. The EPA had proposed that Columbia's compliance with 
emissions limitations in the CAIR and the CSAPR could also serve as compliance with the BART  

94 

 
 
 
 
 
 
 
 
 
 
 
 
regulations for SO2 and NOx emissions. However, this proposal is now uncertain because of the D.C. Circuit 
remanding the CAIR to EPA and vacating the CSAPR. At this time, the BART regulatory obligations, 
compliance strategies and costs remain uncertain. 

Wisconsin State Mercury Rule 
Beginning January 1, 2015, phase two of the Wisconsin mercury rule will require large coal-fired EGUs 
(larger than 150 MW) to reduce mercury emissions by 90%, or choose a multi-pollutant reduction approach, 
which allows a stepped approach to mercury reduction while reducing NOx and SO2 emissions at prescribed 
rates. The Elm Road Units currently meet this requirement. The Columbia co-owners expect to meet the 
90% reduction option by installing baghouses and scrubbers by early 2014 (see the discussion regarding the 
Columbia environmental project below). With the finalization of the EPA's Mercury and Air Toxics 
Standard, or MATs, the WDNR is currently evaluating if the state mercury rule should be supplanted by the 
EPA's rule (see discussion on MATs below). 

Mercury and Air Toxics Standards (MATs) for Utility Boilers (Also Referred to as the Maximum Achievable 
Control Technology, or MACT) 
In December 2011, the EPA finalized its Mercury and Air Toxics Standards for coal and oil-burning EGU 
boilers. MATs will require emissions standards for mercury, non-mercury HAPs metals, and acid gases. 
MGE's Columbia and Elm Road Units are subject to MATs. The Elm Road Unit's current pollution controls 
and Columbia's planned mercury pollution controls (baghouse and scrubbers) are expected to allow both 
facilities to comply with the MATs rule (see the discussion regarding Columbia environmental project 
below). 

National Ambient Air Quality Standards 
The EPA has developed National Ambient Air Quality Standards (NAAQS) for six compounds currently 
identified as criteria pollutants: nitrogen dioxide, particulate matter, ozone, sulfur dioxide, lead, and carbon 
monoxide. The NAAQS for criteria pollutants establish acceptable ambient air levels of each pollutant based 
on a review of their effects to human health and the environment. The EPA is required to review NAAQS 
every five years. New standards that are lower than existing standards may be developed as a result of these 
five-year NAAQS review. Monitoring and modeling data may be used to determine whether areas are in 
compliance. States must develop implementation plans to bring noncomplying areas into compliance and 
such implementation plans can impose new emissions reductions and/or pollution controls requirements on 
stationary sources. 

Certain stationary sources, such as MGE's generation facilities, must meet NAAQS standards for emissions 
that travel offsite. Stationary source air quality modeling is used to determine whether emissions from 
permitted sources meet these NAAQS. Failure to meet NAAQS may require a permit applicant to incur 
capital or operational costs to bring a source into compliance. We cannot predict if MGE's permitted 
stationary sources will have difficulty meeting new standards not previously modeled. Modeling performed 
by the WDNR for MGE's permitted facilities has demonstrated compliance with current NAAQS. Additional 
modeling may be required in future permitting actions. 

MGE tracks NAAQS developments to determine if new standards may affect us. MGE is currently tracking 
two NAAQS developments: (1) determination and placement of monitoring networks in Wisconsin for the 
2010 nitrogen dioxide (NO2) NAAQS (Wisconsin is currently considered in attainment with NO2 NAAQS) 
and (2) stationary source modeling requirements under the 2010 sulfur dioxide (SO2) NAAQS. A concern 
has been raised regarding whether the current EPA-preferred dispersion model may not be accurate for SO2 
stationary source modeling and may overestimate off-site concentrations of SO2 from stationary sources. The 
WDNR is working to resolve issues with the model. 

Reciprocating Internal Combustion Engine (RICE) MACT Standard 
In January 2013, the EPA finalized amendments to its RICE MACT standard. RICE MACT applies to 
industrial or electrical engines that are classified as reciprocating internal combustion engines. Engines 
owned by MGE that would fall under the RICE MACT rule include backup generators and small engines at 
various locations, including our fleet of distributed generators that serve as electric system backup and 
emergency dispatch. MGE is still evaluating the impacts to our engines based on this new standard including 
how the currently finalized rule will impact the dispatch of and/or addition of pollution controls on our 
aforementioned distributed generators.  

95 

 
 
 
 
 
 
 
 
 
 
 
Greenhouse Gas Regulation 
The EPA's Greenhouse Gas "Tailoring Rule" regulates stationary sources for GHG emissions by "phasing 
in" over time different types of facilities subject to Prevention of Significant Deterioration (PSD) pre-
construction program or Title V permitting (i.e. new facilities and existing facilities with certain qualifying 
modifications). Under the Tailoring Rule, covered new or modified sources must meet Best Available 
Control Technology (BACT) requirements for emissions that trigger PSD, including GHG emissions. MGE 
generating facilities may become subject to this rule in the future if modifications at any facilities trigger 
PSD or if MGE invests in new facilities that trigger PSD. 

On March 27, 2012, the EPA proposed greenhouse gas (GHG) New Source Performance Standards (NSPS) 
for coal fired and natural gas combined cycle (NGCC) EGUs. The proposal applies to new EGUs only; the 
EPA has stated that it does not intend for these rules to apply to modified or existing units at this time. The 
proposed NSPS is not anticipated to significantly affect MGE's existing generation units.  

Columbia 

MGE and two other utilities jointly own Columbia, a coal-fired generating facility, which accounts for 
225 MW (29%) of MGE's net summer generating capability. WPL is the plant operator and permit holder, 
and owns 46.2% of Columbia. Wisconsin Public Service Corporation (WPSC) owns a 31.8% interest, and 
MGE owns a 22% interest in Columbia. Based upon current available information, compliance with various 
environmental requirements and initiatives is expected to result in significant additional operating and 
capital expenditures at Columbia.  

Columbia Environmental Project 
In early 2011, the PSCW issued a Certificate and Order authorizing the construction of scrubbers and bag 
houses and associated equipment on Columbia Units 1 and 2 to reduce SO2 and mercury emissions. The 
scrubbers and bag houses are expected to support compliance obligations for current and anticipated air 
quality regulations, including CAIR, CAIR's eventual replacement, the Mercury and Air Toxics Standards 
(MATs) and the Wisconsin Mercury Rule. WPL, the plant operator, currently estimates that MGE's share of 
the capital expenditures required for this project is approximately $140 million. The project is underway and 
estimated to be completed in early 2014. 

MGE's share of various contractual commitments entered for the project as of December 31, 2012, is 
$73.4 million. These costs are expected to be capitalized and included in the consolidated balance sheets of 
MGE Energy and MGE. See Footnote 20 for further information regarding the Columbia environmental 
construction project. 

Title V Operating Permit Petition 
In September 2008, the WDNR issued a Title V renewal operating permit to WPL for Columbia. However, a 
citizen group petitioned the EPA to object to the permit renewal. In October 2009, the EPA issued an order 
granting in part and denying in part the petition and sent the operating permit back to the WDNR for further 
review based on the EPA order. In February 2011, the citizen group involved filed an action against the EPA 
in the U.S. District Court for the Western District of Wisconsin seeking to have the EPA take over the permit 
process. However, on February 4, 2013 the parties involved dismissed the litigation without prejudice. In 
June 2012, the EPA notified the plant operator of its intent to assume responsibility for issuing the renewed 
operating permit for Columbia, but agreed to provide the plant operator with more time to potentially resolve 
the issues raised in the EPA's order. The matter is still pending. MGE believes the permits currently in effect 
for Columbia remain in place at this time. MGE continues to follow these developments and is unable to 
predict the outcome of this matter and its impact on its operations or financial condition. 

Columbia Clean Air Act Litigation 
In December 2009, the EPA sent a notice of violation (NOV) to MGE as one of the co-owners of the 
Columbia generating station. The NOV alleges that WPL, as operator, and the co-owners (WPS and MGE) 
failed to comply with appropriate pre-construction review and permitting requirements and, as a result, 
violated the PSD program requirements, the Title V operating permit requirements of the CAA and the 
Wisconsin State Implementation Plan (SIP). In September 2010, Sierra Club filed a lawsuit against WPL 
alleging violations of the CAA at Columbia and other WPL-operated Wisconsin facilities. WPL responded 
that the projects at Columbia were routine, or not projected to increase emissions, and therefore did not 
violate the permitting requirements of the CAA. MGE and the other Columbia co-owners are defending 
against these allegations while actively pursuing settlement options with the EPA and Sierra Club. 

96 

 
 
 
 
 
 
 
 
 
 
 
MGE believes that the parties have reached a tentative agreement on the general terms of a settlement with 
the EPA and Sierra Club regarding various facilities, including Columbia. Sierra Club has stipulated to a 
dismissal of its lawsuit, without prejudice, while the parties attempt to reach a final settlement. The parties 
are currently negotiating a consent decree based upon those general terms, which may change during the 
negotiations. Once the parties agree to final terms, the court must approve the settlement agreement before it 
becomes final and effective. In accordance with applicable accounting standards, MGE has accrued an 
amount for this matter representing its best estimate of its probable liability, based upon its assessment of the 
settlement discussions. That accrued amount is not material to the financial statements. MGE believes the 
likelihood of a materially greater liability than the accrued amount is remote based upon the current status of 
the settlement discussions.  

f.  Legal Matters - MGE Energy and MGE. 

MGE is involved in various legal matters that are being defended and handled in the normal course of 
business including the Columbia matters discussed above. MGE maintains accruals for such costs that are 
probable of being incurred and subject to reasonable estimation. The accrued amount for these matters is not 
material to the financial statements. 

g.  Elm Road - MGE Energy and MGE. 

The Elm Road Units have an outstanding warranty claim related to costs incurred to repair steam turbine 
corrosion damage. See Footnote 21 for further information regarding these warranty claims. 

h.  Other Commitments. 

MGE Energy holds investments in nonpublic entities. From time to time, these entities require additional 
capital infusions from their investors. MGE Energy has committed to contribute $2.0 million in capital for 
such infusions. The timing of these infusions is dependent on the needs of the investee and is therefore 
uncertain at this time. 

In addition, MGE Energy has a three year agreement with a venture debt fund expiring in December 2013. 
MGE Energy has committed to invest up to a total of $1.0 million into this fund. As of December 31, 2012, 
MGE Energy has $0.5 million remaining in commitments. The timing of infusions is dependent on the needs 
of the fund and is therefore uncertain at this time. 

MGE has a commitment to the City of Madison for certain "green energy" projects. These funds will 
primarily be used to construct or purchase assets that will be owned by MGE and will be included in the 
property, plant, and equipment balance on the MGE Energy's and MGE's consolidated financial statements 
once the costs are incurred. The timing of the capital expenditures is dependent on the feasibility of the 
individual projects. MGE paid $0.3 million in 2012, and expects to pay less than $0.1 million in both 2015 
and 2016. 

MGE has commitments of approximately $0.3 million, which will be made annually (subject to PSCW 
approval) from 2013-2034, for water quality environmental projects.  

MGE has entered into easements related to wind projects. Payments for these easements are $0.1 million in 
each of the next five years. 

19.  Asset Retirement Obligations - MGE Energy and MGE. 

a.  Conditional Asset Retirement Obligations. 

MGE recorded an obligation for the fair value of its legal liability for asset retirement obligations (AROs) 
associated with removal of the West Campus Cogeneration Facility and the Elm Road generating units, 
electric substations, combustion turbine generating units, wind generating facilities, and photovoltaic 
generating facilities, all of which are located on property not owned by MGE Energy and MGE and would 
need to be removed upon the ultimate end of the associated leases. The significant conditional AROs 
identified by MGE included the costs of abandoning in place gas services and mains, the abatement and 
disposal of equipment and buildings contaminated with asbestos and PCBs, and the proper disposal and 
removal of tanks, batteries, and underground cable. Changes in management's assumptions regarding  

97 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
settlement dates, settlement methods, or assigned probabilities could have a material effect on the liabilities 
recorded by MGE at December 31, 2012, as well as the regulatory asset recorded. 

MGE also may have AROs relating to the removal of various assets, such as certain electric and gas 
distribution facilities. These facilities are generally located on property owned by third parties, on which 
MGE is permitted to operate by lease, permit, easement, license, or service agreement. The asset retirement 
obligations associated with these facilities cannot be reasonably determined due to the indeterminate life of 
the related agreements. 

The following table shows a rollforward of the AROs from January 1, 2011, to December 31, 2012. 
Amounts include conditional AROs.

(a)  In 2012, MGE recorded a decrease in revisions in estimated cash flows of $1.3 million based on 

revised asbestos abatement estimates. In 2011, MGE recorded a decrease in revisions in estimated 
cash flows of $1.6 million based on revised remediation timing and cost information for its share of 
the Columbia ash landfill ARO. 

b.  Non-ARO Costs. 

Accumulated costs of removal that are non-ARO obligations are classified within the consolidated financial 
statements as regulatory liabilities. At December 31, 2012 and 2011, there were $14.0 million and 
$13.1 million, respectively, of these costs recorded as regulatory liabilities within the consolidated financial 
statements.  

20.  Columbia Environmental Project Construction - MGE Energy and MGE. 

MGE and two other utilities jointly own Columbia, a coal-fired generating facility. WPL is the plant operator and 
permit holder, and owns 46.2% of Columbia. WPSC owns a 31.8% interest and MGE owns a 22% interest in 
Columbia. In early 2011, the PSCW issued a Certificate and Order authorizing the construction of scrubbers and 
bag houses and associated equipment on Columbia Units 1 and 2 to reduce SO2 and mercury emissions. The 
scrubbers and bag houses are expected to support compliance obligations for current and anticipated air quality 
regulations, including CAIR, CAIR's eventual replacement, the Mercury and Air Toxics Standards (MATS) and 
the Wisconsin Mercury Rule. The operator's current estimate shows that MGE's share of the capital expenditures 
required for this project is approximately $140 million. As of December 31, 2012, MGE had accumulated 
$59.9 million (excluding carrying costs) related to its share of the project, which is reflected in the Construction 
Work in Progress balance on MGE Energy's and MGE's consolidated balance sheets. MGE expects to incur 
capital expenditures as follows: $68 million in 2013 and $12 million in 2014. These amounts may change as a 
result of modifications to the project estimate or timing differences. MGE has recognized $1.4 million (after tax) 
in AFUDC equity related to this project for the year ended December 31, 2012. 

MGE expects that the costs pertaining to this project will be fully recoverable through rates. Additionally, MGE 
is entitled to a carrying cost on the related construction costs at 100% of the determined AFUDC rate. 

21.  Elm Road - MGE Energy and MGE. 

MGE Power Elm Road owns an 8.33% ownership interest in each of two 615 MW coal-fired generating units in 
Oak Creek, Wisconsin. Unit 1 entered commercial operation in February 2010 and Unit 2 entered commercial 
operation in January 2011. MGE Power Elm Road's sole principal asset is that ownership interest in those 
generating units. Each generating unit owner provides its own financing and reflects its respective portion of the 
facility and costs in its financial statements. MGE Power Elm Road has leased the Elm Road Units to MGE 
pursuant to separate facility lease agreements for each unit. These leases were authorized by order of the PSCW 
in accordance with applicable provisions of Wisconsin law that authorized financing of new generation through

facility leases. The PSCW order establishes a cap on the construction costs that may be passed through the lease 
agreements to MGE and its customers, through rates. Additional costs attributable to force majeure events, as 
defined in the leases, do not count against this cap, but are subject to PSCW review and determination that the 
costs were prudently incurred. In December 2012, as part of WEPCO's (the operator and primary owner of the 
Elm Road Units) 2013 Wisconsin rate case, the PSCW determined that 100% of the construction costs for the 
Elm Road Units were prudently incurred, and approved the recovery in rates of more than 99.5% of these costs. 
In addition, the PSCW deferred the final decision regarding the $1.8 million fuel flexibility project (MGE Power 
Elm Road's share) until a future rate proceeding. 

The warranty periods for both of the Elm Road Units have expired. WEPCO and Bechtel (the construction 
contractor for the Elm Road Units) are working through outstanding warranty claims. According to WEPCO, the 
warranty claim for the costs incurred to repair steam turbine corrosion damage identified on both units will be 
resolved through a binding arbitration hearing scheduled for October 2013. In accordance with the contract with 
Bechtel, final acceptance of the units cannot occur until, among other things, all disputes have been settled. 

22.  Adoption of Accounting Principles and Recently Issued Accounting Pronouncements - MGE Energy and 

MGE. 

a.  Fair Value Measurements and Disclosures. 

In May 2011, the FASB issued authoritative guidance within the Codification's Fair Value Measurements 
and Disclosures topic that provides guidance on additional disclosures about fair value measurements, 
specifically related to Level 3 assets and liabilities. This authoritative guidance became effective January 1, 
2012. The authoritative guidance did not have a material financial impact, but required additional 
disclosures. See Footnote 11 for additional information. 

b.  Presentation of Comprehensive Income. 

In June 2011, the FASB issued authoritative guidance within the Codification's Comprehensive Income topic 
that provides guidance on presentation of comprehensive income. Comprehensive income will be presented 
either in a single continuous statement of comprehensive income or in two separate but consecutive 
statements. This authoritative guidance became effective January 1, 2012. The authoritative guidance had an 
effect on our financial statement presentation of comprehensive income. See the Consolidated Statements of 
Comprehensive Income for additional information. 

c.  Disclosures about Offsetting Assets and Liabilities. 

In December 2011, the FASB issued authoritative guidance within the Codification's Balance Sheet topic 
that provides guidance on disclosures about offsetting assets and liabilities. The new disclosure requirements 
mandate that entities disclose both gross and net information for instruments and transactions eligible for 
offset in the balance sheet as well as instruments and transactions subject to a master netting arrangement. In 
addition, the standard requires disclosure of collateral received and posted in connection with a master 
netting arrangement. On January 31, 2013, the FASB issued additional authoritative guidance which 
clarified the scope of disclosures about offsetting assets and liabilities. The revised guidance limits the scope 
of the new balance sheet offsetting disclosures to derivatives, repurchase agreements, and securities lending 
transactions to the extent that they are (1) offset in the financial statements or (2) subject to an enforceable 
master netting arrangement or similar agreement. This authoritative guidance became effective January 1, 
2013. The authoritative guidance will not have a financial impact, but will require additional disclosures. 

23. 

Segment Information - MGE Energy and MGE. 

The electric utility business purchases, generates and distributes electricity, and contracts for transmission 
service. The gas utility business purchases and distributes natural gas and contracts for the transportation of 
natural gas. Both the electric and gas segments operate through MGE Energy's principal subsidiary, MGE. 

The nonregulated energy operations are conducted through MGE Energy's subsidiaries: MGE Power, MGE 
Power Elm Road, and MGE Power West Campus. These subsidiaries have been formed to construct, own and 
lease electric generating capacity to assist MGE. MGE Power Elm Road has an ownership interest in two coal-
fired generating units in Oak Creek, Wisconsin, which are leased to MGE, and MGE Power West Campus owns 
a controlling interest in the electric generation plant of a natural gas-fired cogeneration facility on the UW 
campus. MGE Power West Campus's portion is also leased to MGE. 

99 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The transmission investment segment invests, through MGE Transco, in ATC, a company that provides electric 
transmission services primarily in Wisconsin. See Footnote 4 for further discussion of MGE Transco and the 
investment in ATC. 

The "All Others" segment includes: corporate, CWDC, MAGAEL, and MGE Construct. These entities' 
operations consist of investing in companies and property which relate to the regulated operations, financing the 
regulated operations, or providing construction services to the other subsidiaries. 

General corporate expenses include the cost of executive management, corporate accounting and finance, 
information technology, risk management, human resources and legal functions, and employee benefits that are 
allocated to electric and gas segments based on formulas prescribed by the PSCW. Identifiable assets are those 
used in MGE's operations in each segment. Assets not allocated consist primarily of cash and cash equivalents, 
restricted cash, investments, other accounts receivable, and prepaid assets. 

Sales between our electric and gas segments are based on PSCW approved tariffed rates. Additionally, 
intersegment operations related to the leasing arrangement between our electric segment and MGE Power Elm 
Road/MGE Power West Campus are based on terms previously approved by the PSCW. Consistent with internal 
reporting, management has presented the direct financing capital leases between MGE and MGE Power Elm 
Road/MGE Power West Campus based on actual lease payments included in rates. Lease payments made by 
MGE to MGE Power Elm Road and MGE Power West Campus are shown as operating expenses. The lease 
payments received by MGE Power Elm Road and MGE Power West Campus from MGE are shown as lease 
income in interdepartmental revenues. The depreciation expense associated with the Elm Road Units and WCCF 
is reflected in the nonregulated energy segment.

Item 9A. Controls and Procedures. 

MGE Energy and MGE 

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures 

During the fourth quarter of 2012, each registrant's management, including the principal executive officer and principal 
financial officer, evaluated its disclosure controls and procedures related to the recording, processing, summarization, 
and reporting of information in its periodic reports that it files with the SEC. These disclosure controls and procedures 
have been designed to ensure that material information relating to that registrant, including its subsidiaries, is 
accumulated and made known to that registrant's management, including its principal executive officer and its principal 
financial officer, by other employees of that registrant and its subsidiaries as appropriate to allow timely decisions 
regarding required disclosure, and that this information is recorded, processed, summarized, evaluated, and reported, as 
applicable, within the time periods specified in the SEC's rules and forms. Due to the inherent limitations of control 
systems, not all misstatements may be detected. These inherent limitations include the realities that judgments in 
decision making can be faulty and breakdowns can occur because of simple error or mistake. Additionally, controls can 
be circumvented by the individual acts of some persons, by collusion of two or more people, or by management 
override of the control. Also, the registrants do not control or manage certain of their unconsolidated entities, and thus, 
their access and ability to apply their procedures to those entities is more limited than is the case for their consolidated 
subsidiaries. 

As of December 31, 2012, the principal executive officer and principal financial officer of each registrant concluded 
that such registrant's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the 
Securities Exchange Act of 1934) were effective to accomplish their objectives. Each registrant intends to strive 
continually to improve its disclosure controls and procedures to enhance the quality of its financial reporting. 

During the quarter ended December 31, 2012, there were no changes in MGE Energy or MGE's internal controls over 
financial reporting that materially affected, or are reasonably likely to affect materially, MGE Energy or MGE's internal 
control over financial reporting. 

MGE Energy and MGE 

Management of MGE Energy and MGE are required to assess and report on the effectiveness of its internal control over 
financial reporting as of December 31, 2012. As a result of that assessment, management determined that there were no 
material weaknesses as of December 31, 2012 and, therefore, concluded that MGE Energy and MGE's internal control 
over financial reporting was effective. Management's Report on Internal Control Over Financial Reporting is included 
in Item 8. - Financial Statements and Supplementary Data.

MGE is a wholly owned subsidiary of MGE Energy and does not have a separate audit committee. Instead, that function 
is fulfilled for MGE by the MGE Energy Audit Committee. The Audit Committee approves each engagement of the 
independent registered public accounting firm to render any audit or nonaudit services before the firm is engaged to 
render those services. The Chair of the Audit Committee or other designated Audit Committee member may represent 
the entire Audit Committee for purposes of this approval. Any services approved by the Chair or other designated Audit 
Committee member are reported to the full Audit Committee at the next scheduled Audit Committee meeting. No de 
minimis exceptions to this approval process are allowed under the Audit Committee Charter; and thus, none of the 
services described in the preceding table were approved pursuant to Rule 2-01(c)(7)(i)(C) of Regulation S-X.

Dividend Restrictions 
Dividend payments by MGE to MGE Energy are subject to restrictions arising under a PSCW rate order and, to a 
lesser degree, MGE's first mortgage bonds. The PSCW order limits the amount of dividends that MGE may pay 
MGE Energy when its common equity ratio, calculated in the manner used in the rate proceeding, is less than 
55%. Under those circumstances, MGE may not pay dividends in excess of $39.8 million plus dividends on 
MGE Energy's shares issued in excess of the issued share number used in the rate proceeding forecast if the 
proceeds are invested in MGE. MGE's thirteen month rolling average common equity ratio at December 31, 
2012, is 58.3% as determined under the calculation used in the rate proceeding. MGE paid cash dividends of 
$20.4 million to MGE Energy in 2012. The rate proceeding calculation includes as indebtedness imputed 
amounts for MGE's outstanding purchase power capacity payments and other PSCW adjustments, but does not 
include the indebtedness associated with MGE Power Elm Road or MGE Power West Campus, which are 
consolidated into MGE's financial statements but are not direct obligations of MGE.  

MGE has covenanted with the holders of its first mortgage bonds not to declare or pay any dividend or make any 
other distribution on or purchase any shares of its common stock unless, after giving effect thereto, the aggregate 
amount of all such dividends and distributions and all amounts applied to such purchases, after December 31, 
1945, shall not exceed the earned surplus (retained earnings) accumulated subsequent to December 31, 1945. As 
of December 31, 2012, approximately $281.6 million was available for the payment of dividends under this 
covenant. 

See Footnote 9 and 10 of the Notes to Consolidated Financial Statement for long-term debt and lines of credit 
dividend restrictions.
