letter to our  
shareholders 

Gary J. Wolter, MGE Energy Chairman,  
President and Chief Executive Officer

What does it take to drive change?  

Financial performance 

What does it take to constantly seek the 

best opportunities to improve our business 

for those we serve? Driving change takes  

vision, work and commitment. It builds  

upon past success. This is the way we  

do business at MGE Energy – the way  

we set our course for the future. 

While we encourage innovation and 
forward thinking in our business, we also 
stick to the time-tested fundamentals of 
financial management. 

We invest in our core utility business, 
maintain a strong balance sheet and 
focus on growing long-term value for 
shareholders. This steady approach has 
proven itself during these times of  
prolonged economic uncertainty. 

MGE Energy’s total return has continued 
to steadily increase. A $1,000 invest-
ment in MGE Energy, with dividends 
reinvested, would have grown to  
$1,568 during the five years ending 
Dec. 31, 2011. 

Our stock price reached a record  
high of $47.85 on Dec. 30, 2011.  
MGE Energy’s stock price has outpaced 
major national indices over the last  
10 years. From Dec. 31, 2001,  
through Dec. 31, 2011, our stock  
price grew 77%.

2

In that same 10-year period, our market 
value has grown from $452 million to 
$1.1 billion at the close of 2011. 

In addition to growing the value of your 
company, we remain committed to grow-
ing dividends. In 2011, your Board of 
Directors increased the dividend for the 
36th consecutive year. Our dividends  
per share reached $1.52 in 2011.  
MGE Energy is one of only five investor-
owned gas and electric utilities in the 
nation to increase dividend payments  
for 36 or more consecutive years. 

MGE Energy produced record earnings 
of $2.64 per share in 2011. We have 
produced record earnings in four of the 
last five years. In 2011, our earnings 
benefitted from new electric generation 
going into service and an extremely 
warm summer. 

Assets have steadily grown due to new  
investments, primarily in electric  
generation. As we have grown, our 
regulated subsidiary Madison Gas and 
Electric (MGE) has maintained its high 
credit ratings. For 2011, Standard 
& Poor’s and Moody’s gave MGE the 
highest credit rating in the nation for 
investor-owned, combination utilities. 

National recognition 

MGE Energy’s consistently strong  
financial performance has been recog-
nized nationally.  

For the fourth consecutive year, our 
financial performance was rated among 
the top 40 gas and electric companies 
in the country and as No. 1 in Wisconsin 
by the industry journal Public Utilities 
Fortnightly. 

MGE Energy also consistently ranks as 
a Dividend Achiever by Mergent, Inc. 
For 2011, only 6% of 3,700 dividend-
paying common stocks were included  
on this select list of companies. 

In addition, Value Line, Inc., gave us top 
ratings for both financial strength and 
investment safety. MGE Energy is the 
only investor-owned utility to receive the 
top rating for investment safety among 
20 Midwestern utilities in the central 
U.S. region. 

We remain committed to delivering  
steady, long-term value for our 
shareholders.

Electric vehicles 

MGE is driving change with electric 
vehicles. We are actively preparing for 
a new market of customers—those who 
run their vehicles on electricity. New 
technology is improving electric vehicles, 
batteries and charging stations. MGE 
is at the forefront of this transition to 
vehicles that plug in rather than gas up. 

This year, we are completing a network 
of 26 charging stations across our  
service territory. We anticipate our  
customers will be early adopters of elec-
tric vehicles based on the popularity of 
hybrid vehicles in our service territory. 

To prepare for serving this new energy 
use, we have recruited electric vehicle 
owners to participate in research with 
us. We monitor vehicle charging at our 
stations and at customers’ homes to 
learn how charging patterns may affect 
the electric grid. 

The research will help us understand  
the impact of the technology so we  
can manage it successfully. The  
research also will help us educate our 
customers and foster this new demand 
for electricity.

MGE is a nationwide leader with its network 
of charging stations to serve the emerging 
market of plug-in electric vehicles. New 
smart phone apps allow electric vehicle 
owners to find an available charging station 
in the Madison area.

creasing emissions 

by more than  

50% for both  

sulfur dioxide and 

nitrogen oxides.”

Construction of new emission controls  
for the Columbia Energy Center will begin 
this spring. 

Our next major project will be con-
structing additional emission-reduction  
equipment at the Columbia Energy 
Center near Portage, Wis. MGE owns 
22% of this coal-fired facility. MGE 
plans to invest $140 million toward  
the total project costs of more than 
$600 million. Once the new controls  
begin operation in 2014, they are  
projected to reduce both sulfur dioxide 
and mercury emissions by 90%.

Improving generation

We have made great strides in  
modernizing our fleet of power plants 
and in reducing air emissions. From 
2004 through 2011, MGE has spent 
approximately $348 million on new 
generation. These investments have 
increased generation capacity by 43% 
while at the same time decreasing  
emissions by more than 50% for both 
sulfur dioxide and nitrogen oxides. 

The natural-gas fired West Campus 
Cogeneration Facility in Madison added 
150 megawatts (MW) to our fleet in 
2005. The Top of Iowa wind farm  
added 30 MW three years later. 

Our most recent investment was the  
Elm Road Generating Station in Oak 
Creek, Wis. We receive about 100 MW 
from our 8.3% ownership share of  
this world-class, cleaner coal facility.  
State-of-the-art controls greatly reduce 
emissions compared to a standard  
coal-fired plant.

This new generating capacity enabled 
us to make considerable changes at our 
Blount Generating Station in Madison. 
On Dec. 31, 2011, we retired the  
older, least efficient units at Blount—
representing about 90 MW of capacity. 

We also made a permanent fuel switch. 
Blount no longer operates on coal. The 
plant’s remaining 100 MW of capacity 
now only operates on cleaner-burning 
natural gas.

Installing new technology

Technology touches many aspects of  
our business. We are driving change  
by putting innovative, new technologies 
to work. We learn how they can  
enhance operations and improve  
customer service. 

In 2011, we developed a set of online 
tools for customers. These tools use data 
specific to our service area so customers 
can more effectively understand, track 
and compare their energy use. 

“ We are active  

partners in economic 

development. We 

drive change by 

working to keep  

our local economy 

moving forward.”

MGE installed approximately 4,500 
new meters for large- to medium-sized 
commercial and industrial customers 
in 2011. These meters benefit MGE 
with more detailed and timely data to 
improve load forecasting and capital 
investment planning. 

We also are installing new software to 
manage our distribution grid and to 
interact with the advanced meters.  
MGE consistently ranks in the top 
10 among investor-owned utilities for 
electric reliability. The new distribution 
management system will help  

further reduce service outages and 
improve our response time. Investments 
like these allow us to ensure a depend-
able electric system. 

Smart growth 

At MGE, we are active partners in  
economic development. We drive change 
by working to keep our local economy 
moving forward. MGE supports venture 
funds and business incubators and  
offers a variety of services to businesses 
looking to expand or relocate to our area. 

In 2011, more than $1.4 billion of 
commercial and institutional construc-
tion was under way in the Madison metro 
area. Major companies are making local 
investments. The biotech company 
Promega broke ground on a new  
$90 million manufacturing facility in 
August 2011. TEAM Companies, man-
aged by TDS, recently completed a  
$14 million expansion to one of its  
energy-intensive data centers. 

The Madison economy was rated  
12th strongest among 366 metro areas  
nationwide by the independent economic 
research company Policom. 

Since 2006, the number of high-tech/
biotech companies in the Madison area 
grew from 510 to 610—a 20% increase. 
In addition, high-tech/biotech employ-
ment grew by approximately 3,000 jobs, 
or 11%. These companies contribute  
a total of more than $6 billion to our 
local economy. 

Driving change 

At MGE, we drive change through new 
technology, operational improvements 
and a vision for a better tomorrow. At 
the same time, we remain committed to 
providing excellent customer service and 
to building long-term shareholder value. 

Thank you for your confidence in  
MGE Energy.

MGE is dedicated to helping these local 
high-tech/biotech companies succeed. 
We work as their energy partners—  
offering options such as enhanced  
distribution service and backup  
generation to ensure power quality.

Charging  
electric vehicles 

MGE is a nationwide leader with its  
newly installed network of charging 
stations in the Madison area. We are 
prepared to serve the growing number of 
customers who are choosing to purchase 
electric vehicles. Different technologies 
help serve the electric vehicle market. 
New smart phone apps allow drivers 
to easily check for open and available 
charging stations. A charge pass card 
gets them connected.  

Our customers want the convenience of 
being able to plug in and recharge their 
cars while they are at work, out shopping 
or catching a show downtown. We are 
out ahead—supplying the infrastructure 
and expertise to develop this new market 
of electric use.

This electric plug from a charging station 
connects to electric vehicles. MGE is  
ready for vehicles that plug in rather  
than gas up. Our network of 26 stations  
is nearly completed. 

Employees at Networked Insights discuss 
social media analytics, which they use  
to help business clients improve their  
marketing efforts.  

Growing venture funds 

MGE had the foresight seven years ago 
to help form a venture fund along with 
other investment partners. The Venture 
Debt Fund targets start-up technology  
companies and is vital in launching  
new businesses. Through the fund,  
we have helped 17 start-ups.

In 2011, the Venture Debt Fund entered 
its third round of capitalization. We  
currently are funding nearly a dozen area 
companies, including the local high-tech 
marketing firm Networked Insights. From 
its small start, Networked Insights now 
has Fortune 500 clients and influences  
$5 billion of media spending. It contin-
ues to grow with a recent $20 million 
venture fund investment by Goldman 
Sachs Asset Management.

The Overlook Apartments, owned by Stone 
House Development, has a significant  
solar installation that feeds energy into  
our community grid.

Sparking imaginations

Educating the next generation of energy 
consumers is an important part of our 
role as a community energy company. 
We have partnered on the recent expan-
sion at the Aldo Leopold Nature Center 
in Monona. The center’s new addition 
provides innovative and interactive  
educational opportunities that help  
visitors learn about climate change. 

Outside, on the center’s roof, we have 
installed one of our largest solar energy 
installations. Inside, we have a sig-
nificant interactive exhibit that teaches 
children about renewable energy sources 
and sustainability. The new addition  
officially opens in conjunction with  
Earth Day 2012. 

Students visit MGE’s interactive energy dis-
play at the local Aldo Leopold Nature Center.

Energizing  
our community grid

At MGE, we know our customers  
expect us to be ready with energy  
advice and assistance. Gaining years  
of experience with our own renewable 
energy installations, we lend our  
expertise to customers. 

Through our innovative programs,  
more than 150 customers contribute 
renewable energy to our community 
distribution grid.

Improving our  
distribution system

MGE puts effort and expertise into build-
ing its electric distribution system. As a 
result, our electric reliability consistently 
ranks in the top 10 among investor-
owned utilities nationwide. Through a 
multiyear project, we have upgraded 
the voltage on distribution equipment 
to keep pace with energy demand in 
Madison’s downtown and east side.

Now, we are installing new software to 
manage the distribution system. This 
smarter system can detect problems and 
can allow us to quickly isolate outages.

Improving our distribution system involves  
the hands-on work of experienced line 
technicians and new software creating 
smarter systems that can respond faster. 

Expanding  
high-tech businesses 

Local high-tech businesses depend on 
MGE as an energy partner. We under-
stand their unique energy needs. MGE 
engineers and planners work closely with 
these local companies. We offer custom-
ized infrastructure, such as redundant 
electric feeds and backup generation, to 
provide an extra reliable energy supply.

When the local biotechnology company 
Promega decided to expand, it chose 
Madison over other locations. Now, a 
$90 million specialized manufactur-
ing facility is under construction on its 
campus. In addition, TEAM Companies, 
managed by TDS Hosted and Managed 
Services LLC, recently completed a  
$14 million expansion that triples the 
space of its data center. 

The new Wisconsin Energy Institute  
building is due to open in 2013. The 
institute will focus on research in energy 
storage and renewable energy.

Building a smarter future

More than $1.4 billion of commercial 
and institutional construction took  
place in the Madison area in 2011.  
The University of Wisconsin-Madison  
accounts for more than half of that  
construction with hospital expansions, 
new classrooms and research facilities.

University technology research often 
leads to private-sector development 
and new start-up businesses. We are an 
active partner with the MGE Innovation 
Center in the University Research Park. 
This high-tech business incubator has 
helped more than 70 early-stage compa-
nies grow since it opened in 1989. 

Upgrading our  
substation capacity

We carefully track growth in our service 
area and then strategically upgrade 
substations to ensure we can meet the 
electric load. A $14 million improve-
ment is under way at the Walnut Street 
Substation, which serves the University 
of Wisconsin-Madison campus and sur-
rounding area. With new construction on

campus, the substation’s electric load 
is expected to grow by 2% annually over 
the next five years. MGE also began a 
$2.5 million improvement at the Femrite 
Substation on Madison’s east side. 

The expansion of the Walnut Street Substa-
tion includes a three-story building to safely 
house the control gear.

Ending Blount’s coal use 

MGE discontinued coal burning at its 
Blount Generating Station in Madison at 
the end of 2011. Only cleaner-burning 
natural gas now fuels this plant. In 
2010, MGE began Blount’s transition 
away from coal by making natural gas 
the primary fuel. In addition, we retired 
Blount’s older, least efficient units.

We also invested in a new coal-fired 
facility. The new Elm Road Generating 
Station became fully operational in 
2011. MGE owns 100 megawatts of 
capacity at this new power plant in  
Oak Creek. With its state-of-the-art 
environmental controls, this plant has 
significantly fewer emissions compared 
to Blount’s former coal operations. 

Blount Generating Station’s coal yard is 
now vacant because the Madison plant 
uses only cleaner-burning natural gas.

Unwavering  

commitment drives 

change. Six years 

ago, MGE announced 

major energy-supply 

plan changes. We  

not only met the 

goals of that plan,  

we met them ahead 

of schedule. 

Achieving our  
Energy 2015 objectives

One of our core responsibilities is  
to plan for and provide the reliable  
energy that fuels our community. By 
listening to customers, we make busi-
ness decisions that reflect their needs 
and values. Customer input helped form 
our Energy 2015 plan. This 10-year plan 
detailed our goals for a cleaner and more 
efficient energy supply.

Although it is not yet 2015, MGE  
already has accomplished all the goals 
in our plan.

Growing our renewable energy capacity is 
one way we successfully meet the energy 
needs of our community.

Standing in front of the flower-like solar in-
stallation are (left to right) Roberta Sladky, 
director of Olbrich Gardens; Marty Petillo, 
Olbrich Garden’s green team coordinator; 
and Dave Toso, an MGE senior engineer. 

MGE owns a wind farm in Wisconsin and 
one in Iowa and purchases additional wind 
energy through long-term agreements. 

Growing our  
green leadership 

Energy 2015 pledged to increase  
renewable energy by five to 10 times. 
We have surpassed that goal and now 
have 12 times the wind energy capacity 
we had in 2006. Approximately 9% of 
our customers purchase green energy 
through our Green Power Tomorrow 
program.

In 2011, our program was second in the 
nation among investor-owned utilities 
for its customer participation rate and in 
green power sold as a percentage of all 
electricity sales, according to an annual 
U.S. Department of Energy’s National 
Renewable Energy Laboratory report. 

Showcasing new  
technologies 

Madison’s Olbrich Gardens is now home 
to a 20-foot-tall solar photovoltaic  
installation with triangular-shaped  
modules that form a flower. MGE  
owns and maintains this system as  
one of many technology demonstration 
projects we have installed throughout 
our community. These projects help us 
learn about renewable energy sources 
and the role they can play in meeting 
our community’s energy needs.

Consistent success 

drives change. At 

MGE, we don’t stand 

still. Instead, we seek 

out ways to build on 

past success and 

continuously improve.

Reducing air emissions

We have steadily reduced air emissions 
over time through strategic investments 
and decisions. MGE has modernized its 
fleet of power plants and at the same 
time increased its renewable energy 
capacity. 

Now at the Columbia Energy Center, we 
are taking the next step by constructing 
additional emission-reduction equip-
ment. MGE owns 22% of this coal-fired 
facility and plans to invest $140 million 
toward the total project costs of more 
than $600 million. The new equip-
ment is projected to reduce both sulfur 
dioxide and mercury emissions by 90%. 
Construction is due for completion  
in 2014.

MGE has made continuous improvements 
in reducing air emissions for a cleaner, 
brighter and more sustainable future.

Dan White, CEO of Filament Games, 
launched his successful company in a  
business incubator supported by MGE.

Growing locally 

MGE supports nine local business incu-
bators that serve a total of 125 tenants. 
We cultivate these partnerships to help 
start-up businesses grow their ideas into 
viable products and services. Small  
businesses generate jobs that help grow 
the Madison economy.

One example is Filament Games, a 
production studio that creates online 
educational games. Clients range from 
the National Geographic to Sandra Day 
O’Connor’s iCivics. Filament Games 
graduated from the Madison Enterprise 
Center, a downtown business incubator, 
to new offices. In five years, the  
company has grown from three to  
25 employees with a steady trajectory 
for increasing employment.

Helping our customers 
with energy decisions

MGE has a proven track record 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.

To help customers even further, we have 
created a number of online tools. Our 
newest webtool allows customers to 
compare their homes’ gas and electric 
use to an average Madison home or 
homes of similar size. Customers also 
can compare their energy use from  
year to year. We offer a similar tool  
for businesses. Understanding energy 
use allows our customers to be better 
energy consumers.

New homeowners Patrick and Stephanie 
Shea check mge.com/compare to learn 
more about their home’s energy use. 

Investing in our future

We help build success in our communi-
ties by supporting vital local agencies, 
such as the Boys and Girls Club of  
Dane County. 

James Blilie has benefitted from finan-
cial literacy programs at the Boys and 
Girls Club. At age seven, he opened a

supported by great community and family 
mentors. The eighth-grader adds, “I just 
want to keep investing for the future.”

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 
(a) include 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 
the public from commercial document retrieval services, the website maintained by the SEC at http://www.sec.gov, 
MGE Energy's website at http://www.mgeenergy.com, and MGE's website at http://www.mge.com. Copies may be 
obtained from our websites free of charge. Information contained on MGE Energy's and MGE's websites shall not be 
deemed incorporated into, or to be a part of, this report.

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 8.33% ownership interest 
in two 615 MW 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, 2011, MGE supplied electric service to approximately 139,000 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 
2011, 2010, and 2009 were comprised of the following:

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 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. MGE has one 
purchase power agreement, for a total of 50 MW, with a generator that is located within this market.  

Fuel supply and generation 

MGE satisfies its customers' electric demand with internal generation and purchased power. During the years ended 
December 31, 2011, 2010, and 2009, 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 long-term contracts) from the 
Powder River Basin coal fields located in Wyoming and Montana. MGE's share of the coal inventory supply for the 
Columbia units increased from approximately 21 days on December 31, 2010, to approximately 31 days on 
December 31, 2011. 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. WEC owns approximately 83% of the Elm Road 
Units and is the operator of those units. 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 decreased from approximately 104 days on December 31, 2010, to approximately 36 days on December 31, 2011. 
The larger coal inventory at December 31, 2010, reflected the anticipated start of commercial operations at the second 
Elm Road Unit, which occurred in January 2011. 

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 156 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. The plant no longer burns coal and now operates on natural gas. 

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, 2011, 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. 

On December 31, 2011, MGE supplied natural gas service to approximately 144,000 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 revenues for 2011, 2010, and 2009 were comprised of the following:

Gas operations accounted for approximately 30.5%, 31.5%, and 36.7% of MGE's total 2011, 2010, and 2009 regulated 
revenues, respectively. 

MGE can curtail gas deliveries to its interruptible customers. Approximately 14% of retail gas deliveries in 2011 and 
2010 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 5,430,949 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. WEC 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, 2011, MGE Transco held a 
3.6% ownership interest in ATC. 

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.  

Stay of EPA's Cross State Air Pollution Rule (CSAPR) and Reinstatement of the Clean Air Interstate Rule (CAIR) 
The CAIR, which became effective in 2009, generally requires NOx and SO2 emission reductions from fossil fuel-fired 
electric generating units (25 MW or greater) (EGUs) 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 Generating Station, Columbia, Elm Road, and its combustion 
turbines located in West Marinette and Fitchburg.  

In December 2008, the U.S. Court of Appeals for the D.C. Circuit remanded the CAIR to the EPA for further review. In 
August 2011, the EPA published the Cross-State Air Pollution Rule (CSAPR) to replace the CAIR. Similar to the 
CAIR, CSAPR requires NOx and/or SO2 air emissions reductions fossil fuel-fired EGUs (25 MW or greater) in 28 states 
in the eastern half of the U.S. CSAPR established state emission restrictions, referred to as budgets, for SO2 and NOx 
beginning in 2012 (Phase I). Under CSAPR, SO2 emission budgets in certain states, including Wisconsin, will be 
lowered further in 2014 (Phase II). CSAPR affects the same electric generation units at MGE as CAIR: Blount  

11 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Generating Station, Columbia, Elm Road, and the combustion turbines at West Marinette and Fitchburg. While the 
CAIR relied on a regional cap-and-trade program that allowed unlimited trading amongst states, CSAPR establishes 
enforceable state-wide emission caps with modest variability limits. These caps limit the amount of emissions trading 
allowed to meet compliance requirements. Plants in Wisconsin that are subject to CSAPR have been allocated CSAPR 
emission allowances and will need to hold sufficient allowances to cover emissions on an annual basis. If CSAPR 
allowances are not adequate for a given plant, emissions will need to be reduced at the plant level by fuel-switching, 
installation of controls, curtailment of operations or a combination thereof. CSAPR's 2012 emission caps for the State of 
Wisconsin are significantly lower than Wisconsin's recent annual emissions. MGE's Columbia plant, which is operated 
by WPL (MGE has a 22% ownership interest), has significantly fewer SO2 allocations under CSAPR in 2012 and 2013 
than recent actual emissions.  

In December 2011, the U.S. Court of Appeal for the D.C. Circuit stayed the implementation of CSAPR pending judicial 
review. The ruling leaves the CAIR in place while the court considers the merits and challenges to CSAPR. MGE 
expects to hold sufficient emissions allowances under the CAIR for 2012.  

If CSAPR is reinstated in 2013, the Columbia co-owners will need to evaluate and implement interim operational 
strategies to address anticipated SO2 allowance deficiencies under CSAPR. Current analysis shows that for 2013, 
additional allowances (if available) may need to be purchased, Columbia generation may need to be reduced to comply 
with CSAPR limits, or a combination of these two strategies may be employed. These interim measures may increase 
MGE's costs. MGE expects that the costs pertaining to meeting CSAPR requirements will be fully recoverable through 
rates. Planned new SO2 controls at Columbia are expected to be completed by mid 2014. MGE's share of this project 
will be approximately $140 million. Once the new environmental control project is completed at Columbia, it is 
expected that the plant will emit below anticipated CSAPR allocation levels. 

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). Units that are subject to 
BART and shown to impair Class I Scenic Areas may be required to install pollution controls to combat their 
contribution to visibility at those locations. BART is applied on a case-by-case basis. 

Under CAIR, both the EPA and WDNR concluded that compliance with CAIR emissions limitations would serve as 
compliance with BART requirements for SO2 and NOx emissions. Thus, owners subject to BART obligations had the 
option of purchasing allowances under the CAIR rather than installing pollution controls. In December 2011, the EPA 
proposed that compliance with CSAPR emissions limitations could also serve as compliance with BART for SO2 and 
NOx emissions. However, with the uncertainty regarding the future of CAIR and CSAPR, the future of BART 
regulation and compliance strategies and costs are also uncertain. 

Wisconsin State Mercury Rule 
Wisconsin has adopted a phased approach to mercury emission reductions. Under phase one, as of January 2010, "major 
utilities," such as the operators of Columbia and the Elm Road Units, had to achieve a 40% fleet-wide mercury 
emissions reduction (as compared to an average of 2002, 2003, and 2004 baseline mercury emissions). 

Under phase two, beginning January 1, 2015, large coal-fired electric generating units (larger than 150 MW) must 
reduce mercury emissions by 90%, or follow a multi-pollutant reduction approach, which allows a stepped approach to 
mercury reduction while also reducing NOx and SO2 emissions at prescribed rates. See Footnote 18.g for a discussion of 
these rules and their effects. 

Maximum Achievable Control Technology (MACT) Standards for Hazardous Air Pollutants (HAPs) 
The EPA regulates hazardous air pollutants (HAPs) from various emissions sources under Section 112 of the Clean Air 
Act. MGE is currently tracking and evaluating three MACT requirements that affect our generating facilities.  

MACT for Utility Boilers (Also Referred to as the Mercury and Air Toxics Standards or MATS) 
In December 2011, the EPA finalized its Mercury and Air Toxics Standards for coal and oil-burning electric generating 
unit (EGU) boilers. This rule has been formerly referred to by several names including Utility MACT and National 
Emissions Standards for Hazardous Air Pollutants (NESHAPS) for EGUs. MATS will require standards for mercury, 
non-mercury HAPs metals, and acid gases emitted from coal and oil-burning EGU boilers. Standards differ for new and 
existing units. Standards are further differentiated based on unit categories established by the EPA. Existing facilities 
subject to MATS will be required to test for mercury, particulate matter (as a surrogate for non-mercury metals) and 
SO2 (as a surrogate for acid gases) to determine compliance with the rule. MATS goes into effect in 2015. MGE's 
Columbia and Elm Road Units will need to demonstrate compliance to MATS. MGE is still evaluating the final MATS  

12 

 
 
 
 
 
 
 
 
 
 
 
 
rule and cannot estimate with certainty any potential capital and/or operational expenses associated with the final 
version of this rule at this time. Initial evaluations, however, indicate that the Elm Road Unit's current pollution controls 
and Columbia's planned mercury pollution controls will allow both facilities to comply with the MATS rule. See 
Footnote 18.g for additional information on Columbia's Certificate of Authority for pollution control equipment.  

Reciprocating Internal Combustion Engine (RICE) MACT 
In December 2011, the EPA finalized its RICE MACT standard. RICE MACT applies to combustion turbines that 
contain a reciprocating internal combustion engine. Units subject to RICE MACT may have to install pollution controls 
to meet emissions standards or apply annual hourly limitations to some engines, especially those engines that both serve 
as emergency generators and backup generation. Much of the hourly restriction is based on how an engine is dispatched. 
Under the current RICE MACT, MGE may have to adjust its dispatching of dozens of small generation units used for 
emergency and backup generation. MGE is currently evaluating the cost that will be associated with potential dispatch 
adjustments. 

In January 2012, the EPA published in the Federal Register an intention to propose a revised RICE MACT based on a 
settlement agreement with several power companies. The proposed revisions should increase the annual hourly 
limitations and may reduce the dispatch limitations contained in the current rule. 

MACT for Industrial, Commercial and Institutional (ICI) Boilers 
In March 2011, the EPA finalized its MACT requirements for smaller boilers classified as industrial, commercial or 
institutional. This rule is commonly referred to as ICI Boiler MACT. ICI Boiler MACT includes provisions for ICI 
boilers that burn fossil fuels including coal, oil and natural gas. The rule affects smaller natural gas and oil-burning 
boilers that are used for onsite electricity and do not offer electricity in commerce. MGE has boilers such as these at 
Blount, Columbia, and Elm Road which are expected to meet the rule as it is currently written. However, in 
December 2011, the EPA issued proposed changes to the ICI Boiler MACT rule, referred to as the ICI MACT 
Reconsideration Rule. MGE is currently evaluating the provisions of this newly proposed reconsideration rule but does 
not expect significant operational or financial impacts from this rule at this time.  

Nitrogen Oxide Emission Budget 
In 1998, the EPA issued a rule that imposed a NOx emission budget for emission sources in Wisconsin (NOx SIP Call). 
In 2000, the U.S. Court of Appeals for the D.C. Circuit invalidated a portion of the NOx SIP Call concerning 
Wisconsin's alleged impacts on downwind, 1-hour ozone nonattainment areas. The EPA has also stayed the 
implementation of that portion of the NOx SIP Call concerning Wisconsin's alleged impacts on downwind 8-hour ozone 
nonattainment areas. If the portion of the rule concerning 8-hour ozone nonattainment areas is upheld, the resulting NOx 
emission budget for Wisconsin could potentially affect the level of permissible NOx emissions from Blount, Columbia, 
Elm Road Units and WCCF. NOx SIP Call requirements were set to sunset with the introduction of the CAIR and 
CSAPR. The uncertainty associated with the future of these rules creates the potential for NOx SIP Call to be 
reintroduced in Wisconsin. 

National Ambient Air Quality Standards (NAAQS) 
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 based on effects to human health and the environment. The 
EPA is required to review NAAQS every five years. Monitoring data is used to determine whether areas are in 
compliance with NAAQS. For areas found in noncompliance, states must develop plans to bring those areas into 
compliance. The plans can require emissions reductions and/or pollution controls. Changes in NAAQS standards can 
affect the emission limitations applicable to an emission unit and whether an area is in compliance and thus affect 
compliance costs for activities in those areas, including capital, operational and maintenance expenses at MGE 
generating facilities in those areas. See Footnote 18.g for discussion of recent developments affecting the NAAQS for 
particular matter, ozone, nitrogen dioxide and sulfur dioxide. 

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.g for additional information regarding these matters.

Water quality 

The EPA and WDNR water quality regulations promulgated in accordance with the Federal Water Pollution Control 
Act, or more commonly known as the Clean Water Act (CWA), restrict emissions of pollutants into surface waters and 
regulate surface water quality issues that affect aquatic life, such as water temperatures, intake structures, and wetlands 
filling. The CWA also sets discharge standards requiring 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 discharge limits in water discharge permits. MGE's power plants operate under the 
Wisconsin Pollution Discharge Elimination System (WPDES) permits to ensure compliance with these discharge limits. 
The WDNR has recently published regulations for phosphorus, mercury and thermal discharges from electric-steam 
generating plants. See Footnote 18.g for information regarding these regulations. 

EPA Cooling Water Intake Rules (Section 316(b)) 
In March 2011, the EPA proposed and asked for public comment on standards to reduce entrainment (drawing aquatic 
life into a plant's cooling system) and impingement (trapping aquatic life on screens) from existing structures designed 
to take in cooling water for plants such as electric generating facilities. This rule is commonly referred to as Phase II of 
Section 316(b). Both our Blount and Columbia generating plants are subject to the impingement and entrainment 
aspects of the current proposed rule. Our WCCF plant is subject to the impingement provisions only. The EPA is 
committed to finalize this rule by June 2012. Under the current proposed rule, equipment would need to be installed at 
Blount, WCCF and Columbia to meet these new standards. It is not possible to estimate the potential costs associated 
with the implementation of any of these initiatives until the rule is finalized. 

Solid waste 

Lenz Oil Site 
MGE is listed as a potentially responsible party for a site on the EPA's national priorities Superfund list. The Lenz Oil 
site in Lemont, Illinois, was used for storing and processing waste oil for several years. This site requires cleanup under 
the Comprehensive Environmental Response, Compensation and Liability Act. During 2009, the EPA agreed on a 
remedy for the Lenz Oil site. The remedy included a five year $2.2 million implementation plan. The EPA has asked all 
potentially responsible parties to pay upfront for this five year implementation plan. MGE has provided money for site 
cleanup; however, the cleanup process has not begun. MGE will not know if additional costs exist at the site until 
cleanup is completed. At December 31, 2011, MGE's portion is less than $0.1 million. Management believes that its 
share of the final cleanup costs for the Lenz Oil site will not result in any materially adverse effects on MGE's 
operations, cash flows, or financial position. Insurance may cover a portion of the cleanup costs. Management believes 
that any cleanup costs not covered by insurance will be recovered in current and future rates. 

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. The proposed 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. It is not possible to project the potential costs associated with 
the implementation of any of these initiatives until the rule is finalized. 

Other Environmental Issues 

Polychlorinated Biphenyls (PCBs) Regulations 
On April 7, 2010, the EPA published an Advanced Notice of Proposed Rulemaking (ANPR) for the additional 
regulation of polychlorinated biphenyls (PCBs). The EPA intends to reassess the use, distribution, marking, and storage 
for reuse of liquid PCBs in electric and nonelectric equipment. The rule may require additional testing and potentially a 
phase-out of PCBs in electrical and nonelectrical equipment. MGE has electrical equipment that contains liquid PCBs, 
thus any rule that is developed has a potential to affect our capital or operational costs. We cannot predict the extent of 
this rule's impact until the rule is proposed and/or finalized. 

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. 

14 

 
 
 
 
 
 
 
 
 
 
 
 
 
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.  

EPA's Prevention of Significant Deterioration and Title V Greenhouse Gas Tailoring Rule 
The EPA's Greenhouse Gas "Tailoring Rule" to address the regulation of stationary sources for GHG emissions became 
effective in January 2011. The Tailoring Rule is designed to "phase in" 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. The EPA has 
provided draft guidelines on conducting a BACT Analysis. MGE facilities may become subject to this rule if 
modifications at any facilities trigger PSD or if MGE invests in new facilities that trigger PSD. In addition, MGE's 
facilities will likely need to include GHG emissions information in their Title V permits as they are renewed. 

EPA's Plan to Establish Greenhouse Gas Emission Standards for Fossil-Fuel Fired Utilities 
On December 30, 2010, the EPA announced a proposed schedule for regulating GHGs under Section 111 of the Clean 
Air Act. As part of a settlement agreement with several states and environmental nongovernmental organizations, the 
EPA agreed to propose by July 26, 2011, New Source Performance Standards (NSPS) for new and/or modified fossil-
fuel burning EGUs and proposed guidelines for states' GHG emissions standards for existing EGUs. The EPA has 
delayed the release of a proposed regulation until sometime in 2012. Given the uncertainties associated with this 
initiative, we cannot estimate the effect that compliance may have on our generating operations, cash flows, and 
financial position. 

Climate Change Legislation 

Federal Actions on Climate Change 
Congress is not expected to enact comprehensive climate change legislation in 2012. 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 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 2012. 

Employees 

As of December 31, 2011, MGE had 712 employees. MGE employs 217 employees who are covered by a collective 
bargaining agreement with Local Union 2304 of the International Brotherhood of Electrical Workers and 98 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, 2012. There are also 
5 employees covered by a collective bargaining agreement with Local Union No. 2-111 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, 2012.

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 automatically 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 deferred 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 equity than authorized by the PSCW in MGE's latest rate order. MGE assumes the risks and benefits 
of variances that are within the cost tolerance band.  

16 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 power plant emissions obligations under existing regulations 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. 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, 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  

 

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

17 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 which 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 increased productivity and safety costs. If we are unable to attract and retain an appropriately qualified 
workforce, our operations could be negatively affected. 

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.  

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. 

18 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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. 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.

A significant portion of MGE's electric and gas distribution facilities are located above or underneath highways, streets, 
other public places or property that others own. MGE believes that it has satisfactory rights to use those places or 
property in the form of permits, grants, easements and licenses; however, it has not necessarily undertaken to examine 
the underlying title to the land upon which the rights rest. 

Encumbrances 

The principal plants and properties of MGE are subject to the lien of its Indenture of Mortgage and Deed of Trust dated 
as of January 1, 1946, as amended and supplemented, under which MGE's first mortgage bonds are issued. As of 
December 31, 2011, there were $1.2 million of first mortgage bonds outstanding. See Footnote 9 for additional 
information regarding MGE's first mortgage bonds. 

MGE Power Elm Road has collaterally assigned its right to lease payments from MGE for the Elm Road Units in order 
to secure the repayment of $76.0 million of senior secured notes issued by MGE Power Elm Road. See Footnote 9 for 
additional information regarding these senior notes. 

MGE Power West Campus has collaterally assigned its right to lease payments from MGE for the WCCF in order to

Market for Common Equity 

MGE Energy

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, 2011, is estimated to be 57.3% as 
determined under the calculation used in the rate proceeding. MGE paid cash dividends of $26.6 million to 
MGE Energy in 2011.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. 

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, 
2011, approximately $260.2 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 139,000 customers in Dane County, Wisconsin, including the city of Madison, and purchases and 
distributes natural gas to approximately 144,000 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 undivided 8.33% ownership interest 
in two 615 MW 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 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, 

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

For the year ended December 31, 2011, MGE Energy's earnings were $60.9 million or $2.64 per share compared to 
$57.7 million or $2.50 per share for the same period in the prior year. MGE's earnings for the year ended December 31, 
2011, were $37.3 million compared to $37.7 million for the same period in the prior year.

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 (a 

measure for determining the impact of weather during the heating season) 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.  

Our net income during 2010 compared to 2009 primarily reflects the effects of the following factors: 

  A 10.0% increase in retail electric revenues due to increased customer demand primarily as a result of warmer-

than-normal summer weather, particularly when compared to the cooler-than-normal weather of the prior period. 
Cooling degree days (a measure for determining the impact of weather during the cooling season) increased by 
125% compared to the prior period.  

  An 8.2% decrease in gas sales reflecting lower customer demand due to a milder winter. Heating degree days 

decreased by 8% compared to the prior period. In addition, the 2009 results reflect the receipt by the gas utility of 
the benefit of $1.9 million (pretax) from capacity release revenues and commodity savings as a result of GCIM.  

  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 Elm Road Unit 1 entering commercial operation in 

February 2010.  

During 2011, the following events occurred: 

Elm Road Units: Elm Road Unit 2 entered commercial operation in January 2011. On February 28, 2011, our 
subsidiary, MGE Power Elm Road, which owns an ownership interest in those Units, issued $30 million of its 4.74% 
senior secured notes to refinance a portion of the costs of those Units. The proceeds of those notes were used to repay 
borrowings under MGE Energy's credit facilities.  

Columbia Environmental Project: In March 2011, the PSCW authorized the construction of air emission reduction 
systems and associated equipment on Columbia Units 1 and 2. MGE's share of the capital expenditures required to 
comply with this project will be approximately $140 million, which is expected to be incurred in 2012 through 2014. 

ATC: MGE Transco contributed $0.9 million for voluntary capital contributions to ATC for the year ended 
December 31, 2011.  

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, 2011, MGE has spent $6.0 million related to these projects and has 
outstanding agreements to purchase $0.8 million in smart grid related products for 2012. 

2012 Rate Filing: In December 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% and to increase rates for gas customers by 0.3%. 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. 

During 2012, several items may affect us, including: 

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. MGE is currently unable to predict the impact of these claims on its financial condition 
or results of operations at this time. However, should there ultimately be an adverse outcome, MGE believes it could 
have a significant effect. 

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. 

Columbia Environmental Project: In March 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 comply with this project will be approximately $53 million in 2012, $68 million in 2013, and $15 million in 
2014.

  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:

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. 

Electric depreciation expense 

Electric depreciation expense increased $0.8 million for the year ended December 31, 2011, compared to the same 
period in the prior year. This increase is related to higher levels of electric assets.

  Gas costs/rates. The average retail rate per therm for the year ended December 31, 2011, decreased 4.2% compared 
to the same period in 2010. The primary contributor to this decrease is significantly lower natural gas commodity 
costs.  

  Retail gas deliveries. For the year ended December 31, 2011, retail gas deliveries increased 3.8% compared to the 

same period in 2010, reflecting colder weather during the winter months. 

Cost of gas sold 

For the year ended December 31, 2011, cost of gas sold decreased by $4.3 million, compared to the same period in the 
prior year. The cost per therm of natural gas decreased 7.4%, which resulted in $8.0 million of reduced expense. This 
decrease was partially offset by a 3.5% increase in the volume of gas purchased, which resulted in $3.7 million of 
increased expense.

For the year ended December 31, 2011, increased administrative and general costs were primarily due to increased use 
of outside services. 

Gas depreciation expense 

Gas depreciation expense increased $0.4 million for the year ended December 31, 2011, compared to the same period in 
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 

Transmission investment other income 

For the years ended December 31, 2011 and 2010, other income at the transmission investment segment was 
$8.6 million and $8.5 million, respectively. The transmission investment segment holds our interest in ATC, and its 
income reflects our equity in the earnings of ATC. See Footnote 4.b for additional information concerning ATC and 
summarized financial information regarding ATC. 

Consolidated Other General Taxes - MGE Energy and MGE 

MGE Energy's and MGE's other general taxes increased $0.3 million or 1.7% for the year ended December 31, 2011, 
when compared to the same period in 2010, due to increased Wisconsin license fee tax. The annual license fee tax 
expense is based on the prior year's adjusted operating revenues. Tax rates have not changed. 

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 the Elm Road 
Units and WCCF when those operations are consolidated into MGE's financial statements. 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. Also included in noncontrolling interest, net of tax, is MGE Energy's interest in MGE Transco.  

For the year ended December 31, 2011, MGE Energy (through its wholly owned subsidiary MGE Power) earned 
$14.6 million and $7.5 million, net of tax, for its interest in MGE Power Elm Road and MGE Power West Campus, 
respectively. Additionally, MGE Energy earned $1.9 million, net of tax, for its interest in MGE Transco for the year 
ended December 31, 2011. These amounts are recorded as noncontrolling interest, net of tax, on MGE's consolidated 
statement of income. 

For the year ended December 31, 2010, MGE Energy (through its wholly owned subsidiary MGE Power) earned 
$11.2 million and $7.7 million, net of tax, for its interest in MGE Power Elm Road and MGE Power West Campus, 
respectively. Additionally, MGE Energy earned $1.8 million, net of tax, for its interest in MGE Transco for the year 
ended December 31, 2010. These amounts are recorded as noncontrolling interest, net of tax, on MGE's consolidated 
statement of income.

  Volume. During the year ended December 31, 2010, there was a 4.1% increase in total retail sales volumes compared 
to the same period in the prior year, reflecting the warmer-than-normal weather experienced in the current period 
compared to the cooler-than-normal weather experienced in the prior period. 

  Rates changes. Rates charged to retail customers for the year ended December 31, 2010, were 3.9% or $13.4 million 

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

In December 2009, the PSCW authorized MGE to increase 2010 rates for retail electric customers by 3.3% or 
$11.9 million. The increase in retail electric rates is driven by costs for MGE's share of the Elm Road Units and 
transmission reliability enhancements.  

In May 2009, MGE implemented a credit of $0.00204 per kWh, due to a decrease in actual electric fuel costs. 
During the year ended December 31, 2009, $4.1 million had been credited to electric customers. 

  Fuel refund. As a result of lower than expected fuel and purchased power costs in 2008, a fuel refund was 

approved. The PSCW issued a final order approving the refund amount of $5.5 million, which was applied to 
customers' accounts in March 2009. This refund reduced revenues for the year ended December 31, 2009, but was 
offset in other revenues as described below. 

 

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, 2010, market volumes increased due to more 
internal generation available for sale to the market compared to the prior year, reflecting increased opportunities for 
sales.  

  Other revenues. Other electric revenues decreased $5.4 million for the year ended December 31, 2010, compared to 

the same period in the prior year. This is primarily a result of MGE recording $5.5 million in other electric 
revenues during the year ended December 31, 2009, to offset the impact of the 2008 fuel refund returned to 
customers in 2009.

  Adjustments to revenues. Included in rates for 2010 is a full year of lease payments associated with Elm Road 

Unit 1 and four months of lease payments associated with Elm Road Unit 2. However, the lease payments for Elm 
Road Unit 1 did not begin until February 2010 when the unit went into service and no lease payments were made 
for Elm Road Unit 2, since the unit was not in service until January 12, 2011. As a result, $3.6 million was 
included in adjustments to revenues to defer and return to customers the lease payments collected in rates. 

The adjustments to revenues amount also includes the elimination of carrying costs for WCCF and the Elm Road 
Units that were collected in electric rates, which are recognized as nonregulated energy operating revenues in our 
Nonregulated Energy Operations segment. The amount eliminated was $7.0 million and $10.7 million for the years 
ended December 31, 2010 and 2009, respectively.

The expense for fuel for electric generation increased $5.1 million or 13.7% during the year ended December 31, 2010, 
compared to the same period in the prior year, reflecting higher generation at Elm Road and Columbia. Elm Road 
Unit 1 entered commercial operation on February 2, 2010. 

Purchased power expense decreased by $13.9 million or 16.3% during the year ended December 31, 2010, compared to 
the same period in the prior year. This decrease in expense reflects a $12.4 million or 14.8% decrease in the volume of 
power purchased from third parties and a $1.5 million or 1.8% decrease in the per-unit cost of purchased power, driven 
by Elm Road Unit 1 becoming operational in February 2010 and increased production at Columbia.  

Electric operating and maintenance expenses 

Electric operating and maintenance expenses increased $15.9 million during the year ended December 31, 2010, 
compared to the same period in 2009. The following changes contributed to the net change:

For the year ended December 31, 2010, increased administrative and general costs were primarily due to increased 
pension costs and the amortization of deferred pension expenses from 2009. These pension costs were deferred and 
recovery in rates began in 2010. Transmission costs increased primarily due to an increase in network service fees 
pertaining to ATC. Production costs increased due to Elm Road Unit 1 becoming operational in February 2010. 
Distribution costs increased mainly as a result of increased overhead and underground line expenses.  

Electric depreciation expense 

Electric depreciation expense decreased $1.3 million for the year ended December 31, 2010, compared to the same 
period in the prior year. This decrease was a result of new depreciation rates becoming effective for 2010.

  Retail gas deliveries. For the year ended December 31, 2010, retail gas deliveries decreased 8.8% compared to the 

same period in 2009 as a result of milder weather during the winter months. 

  Gas costs/rates. The average retail rate per therm for the year ended December 31, 2010, decreased 4.4% compared 
to the same period in 2009. The primary contributor to this decrease is significantly lower natural gas commodity 
costs. In December 2009, the PSCW authorized MGE to decrease gas rates 0.74% or $1.5 million.  

 

Transportation and other revenues. Transportation and other revenues decreased a total of $2.3 million primarily due 
to a decrease in income realized under the GCIM. 

Under MGE's GCIM which ended in 2010, if actual gas commodity savings and capacity release revenues are 
above or below a benchmark set by the PSCW, then MGE's gas sales service customers and shareholders share in 
any increased costs or savings per percentages set by the PSCW. For the year ended December 31, 2009, 
shareholders received a benefit from capacity release revenues and commodity savings under GCIM of 
$1.9 million. 

Cost of gas sold 

For the year ended December 31, 2010, cost of gas sold decreased by $19.3 million, compared to the same period in the 
prior year. The volume of gas purchased decreased 7.9% which resulted in $9.7 million of reduced expense. In addition, 
an 8.4% decrease in the cost per therm of natural gas resulted in $9.6 million of reduced expense.  

Gas operating and maintenance expenses 

Gas operating and maintenance expenses increased $2.8 million for the year ended December 31, 2010, compared to the 
same period a year ago. The following changes contributed to the net change.

For the year ended December 31, 2010, increased administrative and general costs were primarily due to increased 
pension costs and the amortization of deferred pension expenses from 2009. The incremental pension costs were 
deferred in 2009 and rate recovery of these costs began in 2010. 

Gas depreciation expense 

Gas depreciation expense decreased $4.3 million for the year ended December 31, 2010, compared to the same period in 
the prior year. This decrease was a result of new depreciation rates becoming effective for 2010. 

Other Income (Deductions), Net 

For the year ended December 31, 2010, other income, net for the electric and gas segments increased by $3.2 million, 
compared to the same period in the prior year. This increase is primarily due to a one-time $2.6 million pretax gain on a 
sale of property to ATC during March 2010 and a one-time $0.5 million pretax gain on a sale of property during 
September 2010.  

Nonregulated Energy Operations - MGE Energy and MGE 

Nonregulated energy operating revenues 

Operating revenues from nonregulated energy operations increased $10.3 million for the year ended December 31, 
2010, when compared to the same period in the prior year, reflecting the commencement of commercial operations at 
Elm Road Unit 1 in February 2010.  

MGE also received approval from the PSCW to collect carrying costs expected to be incurred by MGE Power Elm 
Road during construction of the Elm Road Units. MGE estimates that the total carrying costs on the Elm Road Units 
will be approximately $62.6 million. A portion of this amount is being recognized over the period recovered in rates and 
a portion is being deferred and will be recognized over the period in which the Units are depreciated. See Footnote 21 
for additional information regarding these carrying charges. For the years ended December 31, 2010 and 2009, MGE 
Power Elm Road recognized $4.8 million and $8.1 million, respectively, related to carrying costs on the Elm Road 
Units.  

Nonregulated depreciation expense 

Nonregulated depreciation expense increased $2.5 million for the year ended December 31, 2010, compared to the same 
period in the prior year. This additional depreciation is related to the commencement of commercial operations at Elm 
Road Unit 1 in February 2010. 

Nonregulated energy interest expense, net 

For the years ended December 31, 2010 and 2009, interest expense, net at the nonregulated energy operations segment 
was $2.7 million. Interest expense at the nonregulated energy segment for both the years ended December 31, 2010 and 
2009, includes interest expense incurred on $50 million of borrowings at MGE Power West Campus, which were long-
term and fixed-rate during both periods, and $50 million of borrowings at MGE Power Elm Road, which were long-
term and fixed-rate during 2010. 

Included in the nonregulated interest expense is interdepartmental interest expense and capitalized interest at MGE 
Power Elm Road. During the years ended December 31, 2010 and 2009, MGE Power Elm Road was charged 
$0.3 million and $3.4 million, respectively, in interest expense by Corporate on funds borrowed for the Elm Road Units. 
This expense is eliminated upon consolidation for MGE Energy only. The interest expense at MGE Power Elm Road is 
offset in capitalized interest.  

During the year ended December 31, 2009, MGE Power Elm Road recorded $0.1 million in net interest income on cash 
advanced to ERS for construction of transmission equipment and work done by ATC related to the Elm Road Units. No 
interest income on cash advanced to ERS was recorded during the year ended December 31, 2010.

Transmission Investment Operations - MGE Energy and MGE 

Transmission investment other income 

For the years ended December 31, 2010 and 2009, other income at the transmission investment segment was 
$8.5 million and $8.2 million, respectively. The transmission investment segment holds our interest in ATC, and its 
income reflects our equity in the earnings of ATC. See Footnote 4.b for additional information concerning ATC and 
summarized financial information regarding ATC. 

All Other Nonregulated Operations - MGE Energy 

All other interest income, net 

All other interest income, net for the years ended December 31, 2010 and 2009, was less than $0.1 million and 
$2.8 million, respectively. Interest income for the year ended December 31, 2010, represents $0.3 million in 
interdepartmental interest income from MGE Power Elm Road, offset by $0.3 million in interest expense on short-term 
debt. Interest income for the year ended December 31, 2009, represents $3.4 million in interdepartmental interest 
income from MGE Power Elm Road, partially offset by $0.6 million in interest expense on short-term debt. 

Consolidated Other General Taxes  

MGE Energy's and MGE's other general taxes decreased $0.8 million or 4.5% for the year ended December 31, 2010, 
when compared to the same period in 2009, due to decreased Wisconsin license fee tax. The annual license fee tax 
expense is based on the prior year's adjusted operating revenues. Tax rates have not changed. 

Consolidated Income Taxes - MGE Energy and MGE 

MGE Energy's effective income tax rate for the year ended December 31, 2010, was 37.0% compared to 35.6% for the 
same period in 2009, and MGE's effective income tax rate for the year ended December 31, 2010, was 37.0% compared 
to 35.4% for the same period in 2009. The effective income tax rate differences for both MGE Energy and MGE are 
primarily due to a decrease in the federal wind energy credit. The 10-year tax credit attributable to the Kewaunee wind 
farm lapsed during 2009. 

For 2009 tax return purposes, MGE Energy and MGE changed its income tax methods 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 the WCCF and 
Elm Road Units. MGE Energy owns 100% of MGE Power West Campus and MGE Power Elm Road; 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. Also included in noncontrolling interest, net of 
tax, is MGE Energy's interest in MGE Transco.  

For the year ended December 31, 2010, MGE Energy (through its wholly owned subsidiary MGE Power) earned 
$7.7 million and $11.2 million, net of tax, for its interest in MGE Power West Campus and MGE Power Elm Road, 
respectively. Additionally, MGE Energy earned $1.8 million, net of tax, for its interest in MGE Transco for the year 
ended December 31, 2010. These amounts are recorded as noncontrolling interest, net of tax, on MGE's consolidated 
statement of income. 

For the year ended December 31, 2009, MGE Energy (through its wholly owned subsidiary MGE Power) had earned 
$7.6 million and $4.9 million, net of tax, for its interest in MGE Power West Campus and MGE Power Elm Road, 
respectively. Additionally, MGE Energy had earned $1.5 million, net of tax, for its interest in MGE Transco for the year 
ended December 31, 2009. These amounts are recorded as noncontrolling interest, net of tax, on MGE's consolidated 
statement of income.

Cash Provided by Operating Activities 

MGE Energy 

MGE Energy's consolidated net cash provided by operating activities is derived mainly from the electric and gas 
operations of its principal subsidiary, MGE.  

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 
period in the prior year. 

The cash flows for the year ended December 31, 2011, reflect an $8.3 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 $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. Working capital accounts 
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 by operating activities for the 
year ended December 31, 2011, when compared to the same period in the prior year. These contributions were made to 
comply with the Employee Retirement Income Security Act (ERISA) and the Pension Protection Act of 2006, and 
additional contributions were at management's discretion. 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. 

2010 vs. 2009 

Cash provided by operating activities for the year ended December 31, 2010, was $124.0 million, an increase of 
$6.1 million when compared to the same period in the prior year, primarily due to the benefit of less taxes paid as a 
result of a tax method change in accounting for repairs and higher net income.

Capital expenditures for the year ended December 31, 2010, were $60.1 million. This amount represents a $17.8 million 
decrease from the expenditures made in the same period in the prior year. This decrease is related to decreased 
construction activity of $14.8 million related to the Elm Road Units and a decrease of $3.3 million in other utility 
capital expenditures.

MGE 

2011 vs. 2010 

MGE's cash used for investing activities increased $8.3 million for the year ended December 31, 2011, when compared 
to the same period in the prior year.  

Capital expenditures for the year ended December 31, 2011, were $65.2 million. This amount represents a $5.1 million 
increase from the expenditures made in the same period in the prior year. This increase is related to increased utility 
expenditures of $15.7 million, partially offset by $10.6 million in decreased construction activity related to the Elm 
Road Units. 

Additionally, proceeds of $2.7 million were received for a one time sale of property to ATC in March 2010 and 
$0.6 million were received for a one time sale of property in September 2010.

In March 2011, the PSCW authorized the construction of air emission reduction systems and associated equipments on 
Columbia Units 1 and 2. The operator's current estimate shows that MGE's share of the capital expenditures required to 
comply with this project will be approximately $140 million. As of December 31, 2011, MGE has incurred $4.4 million 
(excluding carrying costs) in construction expenditures at Columbia related to the project. MGE expects to incur capital 
expenditures as follows: $53 million in 2012, $68 million in 2013, and $15 million in 2014. MGE plans to finance this 
project primarily from internal sources, although it expects some long-term debt financing to be necessary. 

MGE Energy's and MGE's liquidity is primarily affected by their construction requirements. On February 4, 2010, MGE 
Power Elm Road issued $50 million of its 5.04% senior secured notes due 2040, the proceeds of which were used to 
repay short-term debt. Also, on February 28, 2011, MGE Power Elm Road issued an additional $30 million of 4.74% 
senior secured notes due 2041. The proceeds from this additional financing were used to repay existing short-term 
indebtedness, consisting of bank loans, which were used to finance a portion of the construction of the Elm Road Units. 

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 2011 capital requirements and cash obligations, including dividend 
payments.

$19.3 million in the prior year.  

On February 4, 2010, MGE Power Elm Road issued $50.0 million of long-term debt. The proceeds from the financing 
were distributed to MGE Energy, which had been using its short-term credit facilities to help finance the Elm Road 
Units. As a result, distributions to parent from noncontrolling interest increased $45.8 million for the year ended 
December 31, 2010. 

Cash used by financing activities for affiliate financing of the Elm Road Units decreased by $8.3 million for the year 
ended December 31, 2010, compared to the prior year. 

In the year ended December 31, 2010, MGE repaid $16.5 million of long-term debt and issued $80.0 million of long-
term debt.  

In addition, for the year ended December 31, 2010, net short-term debt repayments were $30.0 million compared to 
$17.5 million in the prior year.  

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 and $28.8 million for 2011 and 2010, 
respectively, 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, 2011 
and 2010, is estimated to be 57.3% and 58.5%, respectively, as determined under the calculation used in the rate 
proceeding. MGE was not restricted from paying cash dividends in 2011. Cash dividends of $26.6 million and 
$26.2 million were paid by MGE to MGE Energy in 2011 and 2010, 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. 

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, 
2011, approximately $260.2 million was available for the payment of dividends under this covenant.

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, 2011, the ratio of consolidated debt to consolidated total capitalization for each of 
MGE Energy and MGE, as calculated under the credit agreements' covenant, were 39.8% and 36.2%, respectively. See 
Footnote 10, for additional information regarding the credit facilities. 

Capitalization Ratios 

MGE Energy's capitalization ratios were as follows:

*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 results 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. 

Contractual Obligations and Commercial Commitments for MGE Energy and MGE

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, 2011. 

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

(e)  Purchase obligations for 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 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. 

(h)  On April 1, 2012, MGE's $19.3 million, 4.875%, Series B, Industrial Development Revenue Bonds, issued through 

the city of Madison, Wisconsin, are subject to a mandatory repurchase and remarketing, as the result of the 
expiration of the current interest rate period on those bonds. The actual maturity date for these IRB's is October 1, 
2027, and are shown as long-term in the table due to MGE's intent and ability to remarket the bonds for a 
subsequent interest period ending on their maturity date. 

The above amounts do not include any contributions for MGE's pension and postretirement plans. Contributions to the 
plans for 2012 are expected to be approximately $22 million, of which $20 million was paid in January 2012. For 2013 
through 2015 contributions are expected to be between $11 million to $13 million each year. The contributions for years 
after 2015 are currently not yet 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.

made a voluntary $0.4 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.  

MGE Energy's and MGE's commercial commitments as of December 31, 2011, representing commitments triggered by

(a)  Amount includes the facility discussed in (c) plus an additional line of credit. MGE Energy has available at any 
time a $40.0 million committed revolving credit agreement, expiring in July 2015. At December 31, 2011, 
MGE Energy had no borrowings under this credit facility. Accordingly, MGE Energy's available credit under this 
credit facility was $40.0 million at December 31, 2011. 

(b)  MGE has guaranteed repayment of certain receivables it sold to a financial institution under a chattel paper 

agreement. See Footnote 18 of the Notes to Consolidated Financial Statements.  

(c)  Amount includes a $75.0 million committed revolving credit agreement expiring in July 2015. This credit facility is 
used to support commercial paper issuances. At December 31, 2011, there were no borrowings under this facility. 

Blount Station 

In 2006, MGE announced a plan to switch from coal to natural gas and reduce capacity at Blount from 190 MW to 
100 MW by the end of 2011, subject to required regulatory approvals. 

In 2011, MGE received the necessary notification from MISO that the 90 MW of capacity at Blount was no longer 
needed to meet reliability standards and was available for retirement on or after December 31, 2011. As a result, the 
reduction in capacity and the transition to operate on natural gas occurred at Blount at the end of 2011. MGE was 
previously estimating the reduction in capacity to occur in 2013.  

MGE has entered into agreements providing severance benefits to employees affected by this plan. These benefits are 
being recognized ratably over the expected future service period of the employees. Total benefits expected to be paid 
are $0.3 million in 2012. MGE does not plan to seek recovery of severance costs resulting from the reduction of the 
capacity. 

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, 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 

46 

 
 
 
 
 
 
  
   
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
 
  
  
  
  
  
  
 
  
   
  
 
  
 
  
 
  
  
  
 
 
  
  
  
 
  
 
  
  
  
 
 
  
 
  
  
  
  
  
  
 
 
 
 
 
 
 
 
 
 
 
 
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.  

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 investment yields available 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 2011, MGE used an assumed return on assets of 8.25% for pension and 7.39% for other 
postretirement benefits. In 2012, MGE will lower the return on asset assumption from 8.25% to 8.10% for pension 
and lower the postretirement benefit assumption from 7.39% to 7.26%. 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 $1.9 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.

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. 

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.

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 or as a supplemental fuel at several 
coal-fired 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 automatically defer electric fuel-related costs that fall outside a symmetrical cost tolerance band. 
Any over/under recovery of the deferred 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 2011, fuel and purchased power costs included in MGE's base fuel 
rates are $90.8 million. See Footnote 17 of Notes to Consolidated Financial Statements for additional information. 

MGE's gas segment is governed by the purchased gas adjustment clause (PGA). Under the PGA, MGE is able to pass 
through to 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 ranges from eighteen months to four years. 

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 congestion charges. At December 31, 2011, the cost basis of these 
instruments exceeded their fair value by $2.8 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 
beginning June 1, 2012, and ending 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 a derivative contract and is recognized at its fair value on the 
balance sheet. The fair value of the contract at December 31, 2011, reflects a loss position of $39.5 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 

49 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 $1.9 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 2.1% during the year ended 
December 31, 2011, and 11.0% during the year ended December 31, 2010. 

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 includes 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, 2011, 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, 2011, no one customer constituted more than 9% 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. 

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 accompanying 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, 
2011 and 2010, and the results of their operations and their cash flows for each of the three years in the period ended 
December 31, 2011, 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 accompanying 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, 2011, 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 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.

Notes to Consolidated Financial Statements 
December 31, 2011, 2010, and 2009 

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 generally accepted accounting 
principles, 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, 2011 and 2010, the balance is shown net of $3.0 million and $0.5 million, respectively. 
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, coal, 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, 2011 and 2010, were $0.2 million and $0.4 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, 2011 and 2010, were $0.3 million and $2.4 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.  

63 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Additions for significant replacements of property are charged to property, plant, and equipment at cost; 
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  

2011 
3.2 % 
1.6 % 
2.3 % 

2010   
3.3 % 
1.7 % 
2.3 % 

2009   
3.6% 
3.3% 
2.5% 

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, 2011 and 2010, MGE had over 
collected $0.9 million and $4.8 million, respectively. These amounts were recorded 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, estimated customer usage by class, weather 
factors, estimated line losses 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 automatically defer 
electric fuel-related costs, less excess revenues, that fall outside a symmetrical cost tolerance band. Any 
over/under recovery of the deferred 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. 

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 both 2011 and 2010 at 8.36% and 8.77% during 
2009. 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.

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, 2011, and $12.5 million at December 31, 2010. During 2011 and 2010, MGE recorded 
$1.8 million and $1.6 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, 2011. 

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 
$12.9 million, $12.6 million, and $13.7 million for the years ended December 31, 2011, 2010, and 2009, 
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 the 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 the 
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, 2011. 

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 common equity and 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 $76.0 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 long-
term lease. As of December 31, 2011, 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, 2011, 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.

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, 2011, 2010, and 2009, MGE Transco recorded equity earnings from the investment in 
ATC of $8.6 million, $8.5 million, and $8.2 million, respectively. Dividend income received from ATC was 
$6.7 million for both the years ended December 31, 2011 and 2010, and $6.3 million for the year ended 
December 31, 2009. During the year ended December 31, 2011, 2010, and 2009, MGE Transco made 
$0.9 million, $0.7 million and $3.6 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, 2011 and 2010, 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, 2011 and 2010, 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, 2011, 2010, and 2009, is as follows:

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. 

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.g. 

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 this 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. 

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. 

Asset Retirement Obligation  
See Footnote 20 for further discussion.

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.  

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 bonds as part of the rate 
recovery allowed by the PSCW.  

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. 

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.  

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 anticipates rate recovery of the 
incremental tax expense as a result of this legislation and will request recovery to begin in its next base rate case.  

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.  

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 its 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, 2011 and 2010, 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, 2011 and 2010, MGE Energy paid $35.0 million (or $1.52 per share) 
and $34.4 million (or $1.49 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, 2011 and 2010, MGE paid $26.6 million and $26.2 million, respectively, in cash 
dividends to MGE Energy.  

b.  Preferred Stock - MGE Energy and MGE. 

MGE has 1,175,000 shares of $25 par value redeemable preferred stock (cumulative) that is authorized but 
unissued at December 31, 2011 and 2010. 

c.  Dilutive Shares Calculation - MGE Energy.

(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. 

(b)  On April 1, 2012, MGE's $19.3 million, 4.875%, Series B, Industrial Development Revenue Bonds, 

issued through the City of Madison, Wisconsin, are subject to a mandatory repurchase and remarketing, 
as the result of the expiration of the current interest rate period on those bonds. The actual maturity date 
for these IRB's is October 1, 2027, and are shown as long-term debt due to MGE's intent and ability to 
market the bonds for a subsequent interest period ending on their maturity date. 

(c)  On April 1, 2012, MGE's $28.0 million, 5.875%, Industrial Development Revenue Bonds, issued 

through the City of Madison, Wisconsin, have an optional call provision, allowing the bonds to be called 
at par value. The maturity date for these IRB's is October 1, 2034.

(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, 2011, 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, 2011, 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, 2011, 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, 2011, MGE Energy had an unsecured, committed revolving line of credit of $40.0 million 
expiring July 31, 2015. At December 31, 2011, no borrowings were outstanding under this facility.

The agreements require 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, 2011, 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, 2011, 
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, 2011, 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, 2011, 
MGE is in compliance with the covenant requirements.

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

At December 31, 2011 and 2010, the carrying amount of cash, cash equivalents, and outstanding commercial 
paper 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. The estimated fair market value of MGE Energy's and MGE's 
financial instruments are as follows:

b.  Recurring Fair Value Measurements. 

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. 

The following table presents the balances of assets and liabilities measured at fair value on a recurring basis 
for MGE Energy and MGE.

                  against derivative positions with counterparties. 

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 party 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 
with markets with similar exchange traded transactions. The ten-year purchased power agreement (see

Footnote 16) was valued using an internally-developed pricing model and therefore classified as Level 3. 
The model includes both observable and unobservable inputs. Inputs to the model require significant 
management judgment and estimation. The model uses a forward power pricing curve based on exchange-
traded contracts in the electric futures market. As described above, the market prices from this source have 
insufficient volumes and are classified as Level 3 in the fair value hierarchy. To project future prices beyond 
the period in which these quoted market prices are available, MGE calculates the price based on forward gas 
prices and an implied heat rate. MGE 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 incorporates discounting, credit, and model risks. 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 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 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 Weeks 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.  

The following table summarizes the changes in Level 3 assets and liabilities measured at fair value on a 
recurring basis for both MGE Energy and MGE.

(d)  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:

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, 2011, both MGE Energy and MGE had approximately $7.5 million of 
state tax net operating loss deductions that expire between 2012 to 2020 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, 2009, to December 31, 
2011, is as follows:

Unrecognized tax benefits are liabilities shown with Other Deferred Liabilities on the December 31, 2011, 
and December 31, 2010, 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, 2011, MGE Energy and MGE have an unrecognized tax benefit 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 and gas distribution repairs. At December 31, 2010, unrecognized tax 
benefits in the amount of $4.4 million primarily related to temporary tax differences associated with the 
change in income tax method of accounting for electric generation, transmission and distribution repairs. 
Unrecognized tax benefits at December 31, 2011 and 2010, related to federal permanent differences and tax 
credits is $0.2 million, the realization of which would not significantly impact the effective tax rate. 

The unrecognized tax benefits at December 31, 2011, 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, the 2007 federal return 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. At December 31, 2011, MGE has a regulatory 
asset of $2.9 million representing the revenue requirement related to PPACA taxes payable, calculated at 
current statutory 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 
$1.8 million, $1.6 million, and $1.3 million in 2011, 2010, and 2009, 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 8.25% and 8.5% for 2011 and 2010, 
respectively. In 2012, MGE will lower the return on asset assumption from 8.25% to 8.1%. 

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 2011 and 2010, and the target allocation for 2012, 
by asset category, follows: 

Equity securities..................................
Debt 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, 2011. 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, 2011, 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, 2011: 

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 $23.5 million and $20.9 million at the end 
of 2011 and 2010, respectively. The expected long-term rate of return on these plan assets is 7.39% and 
7.44% for 2011 and 2010, respectively. In 2012, MGE will lower the return on asset assumption from 7.39% 
to 7.26%. 

Of the above amounts, $20.1 million and $17.9 million at the end of 2011 and 2010, 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.

long-term liability, and a $148.5 million regulatory asset in the balance sheet to properly reflect the unfunded 
status of the plans. 

At December 31, 2010, MGE Energy and MGE included a $0.8 million current liability, a $123.6 million 
long-term liability, and a $78.7 million regulatory asset in the balance sheet to properly reflect the unfunded

i.  Expected Cash Flows. 

Contributions to the plans for 2012 are expected to be approximately $22 million, of which $20 million was 
paid in January 2012. For 2013 through 2015 contributions are expected to be between $11 million to 
$13 million each year. The contributions for years after 2015 are currently not yet 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 2011, MGE made $23.7 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 both the year ended December 31, 2011 and 2010, $2.6 million has been 
recovered in rates.

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 
the 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, 2011, 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, the Company 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 the years ended December 31, 2011, 2010, and 2009, MGE recorded $1.4 million, $1.2 million and 
$0.8 million, respectively, in compensation expense as a result of awards under the Performance Unit Plan. In 
January 2011, cash payments of $0.5 million were distributed relating to awards that became payable under the 
Performance Unit Plan. No forfeitures occurred during the years ended December 31, 2011, 2010, and 2009. At 
December 31, 2011, $3.1 million of outstanding awards are vested, but 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 has one purchase power agreement, for a total of 50 MW, with a generator that is located 
within this market.  

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 $102.1 million, 
$94.9 million, and $74.4 million reduction to sales to the market and purchased power expense for the years 
ended December 31, 2011, 2010, and 2009, 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 ranges from eighteen 
months to 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:

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, 2011 
and 2010, MGE Energy and MGE had $3.0 million and $0.5 million, respectively, 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 and PJM 
markets, 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 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, 2011 and 
2010, the cost basis of exchange traded derivatives and FTRs exceeded their fair value by $2.8 million and 
$0.2 million, respectively. 

MGE has also entered into 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 the 
option to purchase power during a period of time preceding that base term as well as 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 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, 2011 and 2010, reflects a loss position of 
$39.5 million and $19.0 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 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 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. Certain counterparties extend MGE a credit limit. If MGE exceeds these 
limits, the counterparties may require collateral to be posted. As of December 31, 2011 and 2010, 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, 2011, no counterparties have defaulted. 

17.  Rate Matters - MGE Energy and MGE. 

a.  Rate Proceedings. 

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 is 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. 

On December 18, 2008, under a limited reopener, the PSCW authorized MGE to decrease 2009 rates for 
retail electric customers by 0.74% or $2.7 million, while gas rates remained unchanged from 2008. The 
decrease in retail electric rates was driven by a decrease in fuel and purchased power costs, decrease in costs

associated with the Elm Road Units and a decrease in ATC transmission costs. The PSCW also approved 
deferred accounting for incremental pension and other postretirement benefit costs above the levels included 
in rates.  

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 automatically defer electric fuel-related costs that fall outside a symmetrical cost 
tolerance band. Any over/under recovery of the deferred costs is determined on an annual basis and will be 
adjusted in future billings to electric retail customers. 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, 2011, MGE did not defer any electric fuel-related costs. In 2010, a refund of 
$0.3 million of over collected 2009 fuel costs was refunded on customers' April 2010 bills. In May 2009, the 
PSCW authorized an interim fuel credit as a result of decreased actual electric fuel costs. The order was 
subject to refund with interest at 10.8%. The interim fuel credit resulted in $4.6 million reduction in 
customer revenues. In 2008, MGE recorded a $5.5 million fuel reduction to other electric revenues to 
account for a fuel refund. In March 2009, the PSCW completed their audit of the 2008 electric fuel costs and 
issued a final order, which applied this refund to customers' accounts in March 2009. 

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, 2011, 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, 2012. At December 31, 2011, 2010, and 2009, respectively, MGE had sold a $4.3 million, 
$3.6 million, and $3.7 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 December 31, 
2011, MGE had recorded a servicing asset of $0.2 million. At each of the years ended December 31, 2010, 
and 2009, MGE had recorded a servicing asset of $0.1 million. MGE recognized a gain of $0.1 million for 
the year ended December 31, 2011, in connection with the sale of loan assets. MGE recognized gains of less 
than $0.1 million for each of the years ended December 31, 2010, and 2009, in connection with the sale of 
loan assets. The servicing asset amount amortized in 2011 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 2011, 2010, and 2009, MGE received approximately $1.5 million, $0.5 million, and 
$0.6 million, respectively, from the financial institution for the sale of loan assets. During those same years, 
payments of $0.8 million, $0.7 million, and $0.8 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, 2011, 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 associated customer loan. Principal payments for the next five years on the 
loans are:

c.  Wind Development Rights - MGE Energy and MGE. 

In August 2011, MGE Energy, through its subsidiary MAGAEL, LLC, terminated two existing wind 
development agreements. The termination of these agreements resulted in the termination of any further 
rights or obligations related to these wind development sites in Iowa. The original agreements were entered 
into in June 2009 to purchase land development rights, including land option agreements, electrical 
interconnection rights, wind data, engineering plans, licenses, permits, and governmental approvals for two 
wind development sites. These wind development rights potentially would have been used to develop wind 
farms of approximately 175 MW in three counties in Iowa. The payments made pursuant to these agreements 
totaled $2.0 million and will be returned to MAGAEL, LLC. As of December 31, 2011, the principal and 
interest balance outstanding is $1.0 million, expected to be received by December 31, 2012. 

d.  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.

e.  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, 2011, MGE has spent $6.0 million related to 
these projects and has outstanding agreements to purchase $0.8 million in smart grid related products for 
2012. 

f.  Receivable - Margin Account - MGE Energy and MGE. 

MGE enters into financial transactions to hedge its costs for fuel used in electric generation, purchased 
power, and cost of gas sold to customers. These transactions are conducted pursuant to a PSCW-approved 
risk management plan through an account held at MF Global. As a result of a bankruptcy filing on 
October 31, 2011, by affiliated MF Global entities, the Chicago Mercantile Exchange froze all MF Global-
related accounts (including MGE's account). As of December 31, 2011, MGE has approximately 
$0.7 million remaining in a customer-segregated margin account held at MF Global. At this time, MGE is 
unable to predict the ultimate impact of these events, including any regulatory recovery related to any losses 
we may incur. 

g.  Environmental - MGE Energy and MGE. 

Solid Waste 

Lenz Oil Site 
MGE is listed as a potentially responsible party for a site on the EPA's national priorities Superfund list. The 
Lenz Oil site in Lemont, Illinois, was used for storing and processing waste oil for several years. This site 
requires cleanup under the Comprehensive Environmental Response, Compensation and Liability Act. 
During 2009, the EPA agreed on a remedy for the Lenz Oil site. The remedy included a five year 
$2.2 million implementation plan. The EPA has asked all potentially responsible parties to pay upfront for 
this five year implementation plan. MGE has provided money for site cleanup; however, the cleanup process 
has not begun. MGE will not know if additional costs exist at the site until cleanup is completed. At 
December 31, 2011, MGE's portion is less than $0.1 million. Management believes that its share of the final 
cleanup costs for the Lenz Oil site will not result in any materially adverse effects on MGE's operations, cash 
flows, or financial position. Insurance may cover a portion of the cleanup costs. Management believes that 
any cleanup costs not covered by insurance will be recovered in current and future rates. 

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 
emissions 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 WDNR has recently published regulations for 
phosphorus, mercury and thermal discharges from electric-steam generating plants. 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. 

94 

 
 
 
 
 
  
  
 
 
 
  
 
 
 
 
 
 
 
 
 
 
WPDES Thermal Discharge Rules 
Effective October 2010, Wisconsin Pollution Discharge Elimination System (WPDES) permit holders that 
add heat to their discharge, or discharge to a surface water body at a temperature different from which they 
receive intake water, will need to comply with thermal discharge requirements upon permit(s) renewal. MGE 
submitted a thermal discharge analysis with its most recent Blount WPDES permit application, showing 
discharges within acceptable limits. If the WNDR does not concur with MGE's analysis, additional studies 
could be required at Blount. The Columbia WPDES permit renewal is currently under review and the 
thermal requirements will be documented in the eventual permit. Elm Road has an existing thermal limit in 
its permit. The WNDR may alter this limit when it renews the permit for the Elm Road Units. If any of 
MGE's plants are unable to demonstrate compliance with its associated WPDES permit requirements, then 
we may incur capital costs associated with plant modifications or operational controls or limitations. 

WPDES Phosphorus Nutrient Standards 
In December 2010, the WDNR established water quality standards for phosphorus and effluent limitations 
for permitted discharges into specific waterbodies. Phosphorus limitations will be added to water effluent 
discharge permits. Because the WDNR will be developing site-specific phosphorus limits based on the status 
of the receiving waterbody, it is difficult to predict what limits will be at MGE's facilities subject to these 
standards (Blount, Columbia, Elm Road and WCCF). MGE is awaiting phosphorus limits tied to its latest 
water effluent discharge permit renewal for Blount. MGE may incur additional capital or operational 
expenditures and/or need to install additional pollution controls to meet the new phosphorus limits. MGE 
has, however, identified potential compliance options and believes compliance can be managed without 
significant capital investments. 

EPA Cooling Water Intake Rules (Section 316(b)) 
In March 2011, the EPA proposed and asked for public comment on standards to reduce entrainment 
(drawing aquatic life into a plant's cooling system) and impingement (trapping aquatic life on screens) from 
existing structures designed to take in cooling water for plants such as electric generating facilities. This rule 
is commonly referred to as Phase II of Section 316(b). Both our Blount and Columbia generating plants are 
subject to the impingement and entrainment aspects of the current proposed rules. Our WCCF plant is 
subject to the impingement provisions only. The EPA is committed to finalize this rule by June 2012. Under 
the current proposed rule, equipment would need to be installed at Blount, WCCF and Columbia to meet 
these new standards. It is not possible to estimate the potential costs associated with the implementation of 
any of these initiatives until the rule is finalized. 

  WPDES Mercury Discharge Limit 
  WPDES permit holders in coal-fired electric power plants, are required to meet mercury effluent limits. If 
permit holders do not meet the mercury limits, then they must apply for a variance as part of their next 
permit renewal with the WDNR. MGE applied for a mercury variance for Blount as part of its permit 
renewal, in the fall of 2010. Final action on the permit renewal is expected in 2012. If the variance is not 
approved, MGE may have operational or capital costs associated with meeting the mercury effluent limits 
when the permit is renewed but we cannot estimate the cost of that compliance at this time.  

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. 

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 
the Clean Air Interstate Rule (CAIR) and related Transport Rule, maximum achievable control technology 
(MACT) standards, new source performance standards (NSPS), the Clean Air Visibility Rule (also known as 
the Regional Haze Rule), and state mercury emissions limits are expected to result in additional operating 
and capital expenditure costs for electric generating units.

Stay of EPA's Cross State Air Pollution Rule (CSAPR) and Reinstatement of the Clean Air Interstate Rule 
(CAIR) 
The CAIR, which became effective in 2009, generally requires NOx and SO2 emission reductions from fossil 
fuel-fired electric generating units (25 MW or greater) (EGUs) 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 Generating Station, Columbia, Elm Road, and its combustion turbines located in West Marinette and 
Fitchburg.  

In December 2008, the U.S. Court of Appeals for the D.C. Circuit remanded the CAIR to the EPA for further 
review. In August 2011, the EPA published the Cross-State Air Pollution Rule (CSAPR) to replace the 
CAIR. Similar to the CAIR, CSAPR requires NOx and/or SO2 air emissions reductions from fossil fuel-fired 
EGUs (25 MW or greater) in 28 states in the eastern half of the U.S. CSAPR established state emission 
restrictions, referred to as budgets, for SO2 and NOx beginning in 2012 (Phase I). Under CSAPR, SO2 
emission budgets in certain states, including Wisconsin, will be lowered further in 2014 (Phase II). CSAPR 
affects the same electric generation units at MGE as CAIR: Blount Generating Station, Columbia, Elm Road, 
and its combustion turbines located at West Marinette and Fitchburg. While the CAIR relied on a regional 
cap-and-trade program that allowed unlimited trading amongst states, CSAPR establishes enforceable state-
wide emission caps with modest variability limits. These caps limit the amount of emissions trading allowed 
to meet compliance requirements. Plants in Wisconsin that are subject to CSAPR have been allocated 
CSAPR allowances and will need to hold sufficient allowances to cover emissions on an annual basis. If 
CSAPR allowances are not adequate for a given plant, emissions will need to be reduced at the plant level by 
fuel-switching, installation of controls, curtailment of operations or a combination thereof. CSAPR's 2012 
emission caps for the State of Wisconsin are significantly lower than Wisconsin's recent annual emissions. 
MGE's Columbia plant, which is operated by WPL (MGE has a 22% ownership interest), has significantly 
fewer SO2 allocations under CSAPR in 2012 and 2013 than recent actual emissions.  

In December 2011, the U.S. Court of Appeal for the D.C. Circuit stayed CSAPR pending judicial review. 
The ruling leaves the CAIR in place while the court considers the merits and challenges to CSAPR. MGE 
expects to hold sufficient emissions allowances under the CAIR for 2012.  

If CSAPR is reinstated in 2013, the Columbia co-owners will need to evaluate and implement interim 
operational strategies to address anticipated SO2 allowance deficiencies under CSAPR. Current analysis 
shows that for 2013, additional allowances (if available) may need to be purchased, Columbia generation 
may need to be reduced to comply with CSAPR limits, or a combination of these two strategies may be 
employed. These interim measures may increase MGE's fuel costs. MGE expects that the costs pertaining to 
meeting CSAPR requirements will be fully recoverable through rates. Planned new SO2 controls at 
Columbia are expected to be completed by mid 2014. MGE's share of this project will be approximately 
$140 million. Once the new environmental control project is completed at Columbia, it is expected that the 
plant will emit below anticipated CSAPR allocation levels. 

Wisconsin State Mercury Rule 
As of January 2010, "major utilities" (such as the operators of the Columbia and Elm Road Units) had to 
achieve a 40% fleet-wide mercury reduction (as compared to an average of 2002, 2003, and 2004 baseline 
mercury emissions). Elm Road's majority owner has installed highly efficient mercury-reduction equipment 
on its units. The Columbia operator plans to meet its fleet-wide reduction in a number of ways, including 
utilizing mercury reduction equipment installed on one of Columbia's units. We do not anticipate any 
changes in dispatch at Columbia or the Elm Road Units as a result of this fleet-wide reduction requirement. 
However, any dispatch changes, if they were to become necessary to meet this requirement, could negatively 
affect our operating costs.  

Beginning January 1, 2015, phase two of the rule will require large coal-fired electric generating units (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 Columbia operator has indicated that it plans to meet the 90% reduction option by installing pollution 
controls needed to meet this and other rules (see the discussion regarding Columbia below).  

96 

 
 
 
 
 
 
 
 
 
 
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. 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 require emissions reductions and/or pollution controls. 

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. 

Particulate Matter NAAQS 
In October 2009, the EPA designated the counties where the Elm Road Units are located as not complying 
with the 24-hour NAAQS for fine particulate matter. The State of Wisconsin will need to develop a plan by 
early 2012 to address the affected counties. Implementation of the fine particulate NAAQS could affect 
capital, operational and maintenance expenses at MGE generating facilities in those areas.  

In February 2009, the U.S. Court of Appeals for the D.C. Circuit remanded the annual fine particulate matter 
standards to the EPA for further review. The current primary hourly and annual standards will remain in 
place as the EPA undertakes that review. In addition, the EPA was scheduled to evaluate particulate matter 
NAAQS in 2011 as part of its five-year review. The EPA has not completed this evaluation but is expected 
to propose rule changes in 2012. If the standards become more stringent as a result of any of these actions, 
more counties where our generation is located could be in nonattainment; however, that cannot be known 
until the standards are finalized. 

Nitrogen Dioxide NAAQS 
In January 2010, the EPA adopted a nitrogen dioxide (NO2) NAAQS focusing on near-roadway exposures to 
NO2. In February 2011, Wisconsin Governor Scott Walker recommended that all counties be considered 
unclassified (neither in attainment nor in nonattainment with the rule) for NO2 until data monitoring is 
improved in Wisconsin. In June 2011, the EPA responded to Governor Walker's recommendation with a 
letter indicating their intent to designate all areas in Wisconsin as unclassified/attainment. The EPA also 
stated that they intend to reclassify areas as appropriate once data monitoring is in place and sufficient data is 
available to make determinations. A final decision from the EPA on NO2 NAAQS designations is expected 
in early 2012. It is unclear at this time whether the counties in which MGE's generating facilities reside will 
be in attainment or nonattainment with this rule once monitoring data is collected and analyzed. 

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.  

Certificate of Authority 
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 or CSAPR, the Utility MACT Rule and the Wisconsin Mercury Rule. 
The operator's current estimate shows that MGE's share of the capital expenditures required for this project 
will be approximately $140 million. As of December 31, 2011, MGE had incurred $4.4 million (excluding 
carrying costs) in construction expenditures at Columbia related to the proposed project. This project is also 
expected to result in an increase to Columbia's ongoing operating expenses. 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 a 100% of the determined AFUDC rate. 

97 

 
 
 
 
 
 
 
 
 
 
 
 
As of December 31, 2011, Columbia entered into various contractual commitments with vendors for a 
portion of the aforementioned expenditures as well as other Columbia environmental projects. MGE is 
indirectly a party to these agreements as a result of its joint ownership of Columbia and is also contractually 
obligated, under the applicable ownership and operating agreements. MGE's share of these commitments is 
$1.5 million for 2012. These costs are expected to be capitalized and included in the consolidated balance 
sheets of MGE Energy and MGE. 

Title V Operating Permit Petition 
In September 2008, the WDNR issued a Title V renewal operating permit to WPL for Columbia. A citizen 
group petitioned the EPA to object to the issuance of 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. The WDNR took various preliminary actions and in 
February 2011, issued a letter stating its determination not to issue either the proposed construction permit or 
a revised operating permit for Columbia. 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. In May 2011, the WDNR proposed a revised operating permit for Columbia. The 
Columbia owners commented on the WDNR's draft permit and are awaiting the WDNR's response. 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 financial or 
operational conditions. 

Columbia Clean Air Act Litigation 
In December 2009, the EPA sent a Notice and Finding of Violation (NOV) to MGE as one of the co-owners 
of Columbia. The NOV alleges that WPL, as operator, and the Columbia co-owners failed to comply with 
appropriate pre-construction review and permitting requirements and as a result violated the PSD program 
requirements, Title V Operating Permit requirements of the CAA and the Wisconsin SIP. The parties are 
exploring possible settlement. 

In September 2010, Sierra Club filed a civil lawsuit against WPL alleging violations of the CAA at 
Columbia and other Wisconsin facilities operated by WPL. The Sierra Club and the co-owners are engaged 
in settlement discussions. The parties recently requested and received a temporary stay of proceedings to 
further explore settlement options. The trial date is now scheduled for December 2012. During the 
February 15, 2012 status conference, the Court reaffirmed the December 2012 trial date, but set a pre-trial 
schedule that allows the parties to work toward settlement.  

MGE and the other co-owners of Columbia are defending against these allegations while also exploring 
settlement options with the EPA and Sierra Club. WPL has informed MGE that WPL believes the projects at 
Columbia were routine or not projected to increase emissions and therefore did not violate the permitting 
requirements of the CAA.  

In response to similar EPA CAA enforcement initiatives, certain utilities have elected to settle with the EPA, 
while others have elected to litigate. If the EPA and/or Sierra Club successfully prove their claims that 
projects completed in the past at Columbia required either state or federal CAA permits, MGE may, under 
the applicable statutes, be required to pay civil penalties in amounts of up to $37,500 per day for each 
violation and/or complete actions for injunctive relief. Payment of fines and/or injunctive relief could be 
included in a settlement outcome. Injunctive relief contained in settlements or court-ordered remedies for 
other utilities in similar matters required the installation of pollution control technology, changed operating 
conditions (including use of alternative fuels other than coal), surrender of excess emission trading 
allowances, caps for emissions and limitations on generation (including retirement of generating units) and 
other beneficial environmental projects. If similar remedies are required for final resolution of these matters 
at Columbia, MGE would likely incur additional capital and operating expenditures. At this time, MGE is 
unable to predict with certainty the impact of these claims on its financial condition or results of operations 
but believes that should there ultimately be an adverse outcome, it could have a significant effect.  

h.  Other Legal Matters - MGE Energy and MGE. 

  MGE is involved in various other legal matters that are being defended and handled in the normal course of 

business. MGE maintains accruals for such costs that are probable of being incurred and subject to 
reasonable estimation. MGE has accrued for such matters in the financial statements. The ultimate outcomes 
of such matters are uncertain and may have an adverse effect on MGE Energy's and MGE's results of 
operations, financial position, or cash flows. 

98 

 
 
 
 
 
 
 
 
 
 
 
i.  Other Commitments. 

  MGE Energy holds an investment in a nonpublic entity. From time to time, this entity requires additional 
capital infusions from their investors. MGE Energy has committed to contribute $0.2 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, 2011, 
MGE Energy has $0.4 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 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 2011, and expects to pay $0.4 million in 2012. 

MGE's has commitments of approximately $0.3 million, which will be made annually (subject to PSCW 
approval) from 2012-2034, 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.  Blount Station - MGE Energy and MGE. 

In 2006, MGE announced a plan to switch from coal to natural gas and reduce capacity at Blount from 190 MW 
to 100 MW by the end of 2011, subject to required regulatory approvals.  

In 2011, MGE received the necessary notification from MISO that the 90 MW of capacity at Blount was no 
longer needed to meet reliability standards and was available for retirement on or after December 31, 2011. As a 
result, the reduction in capacity and the transition to operate on natural gas occurred at Blount at the end of 2011. 
MGE was previously estimating the reduction in capacity to occur in 2013. 

MGE has entered into agreements providing severance benefits to employees affected by this plan. These 
benefits are being recognized ratably over the expected future service period of the employees. Total benefits 
expected to be paid are $0.3 million in 2012. MGE does not plan to seek recovery of severance costs resulting 
from the reduction of the capacity. 

The following table presents the activity in the restructuring accrual from December 31, 2010, through 
December 31, 2011:

The exit plan has also resulted in accelerated depreciation for the Blount assets retired in 2011. The majority of 
these assets are being recovered in rates over a four-year period that began in 2008, with the remaining balance 
recovered by the end of 2013. For the years ended December 31, 2011 and 2010, $3.4 million of accelerated 
depreciation expense had been recognized and recovered in rates each year.

20.  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 removing 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 lease. 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 settlement dates, settlement methods, or assigned probabilities could have a material effect on the 
liabilities recorded by MGE at December 31, 2011, 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, 2010, to December 31, 2011. 
Amounts include conditional AROs.

(a)  In 2011 and 2010, MGE recorded revisions in estimated cash flows of a decrease of $1.6 million and an 

increase of $0.7 million, respectively, based on revised remediation timing and cost information for its 
share of the Columbia ash landfill ARO. In 2010, MGE recorded revisions in estimated cash flows of an 
increase of $1.2 million based on revised remediation timing and cost information for its wind 
generating facilities ARO. 

b.  Non-ARO Costs. 

Accumulated costs of removal that are non-ARO obligations are classified within the financial statements as 
regulatory liabilities. At December 31, 2011 and 2010, there were $13.1 million and $12.3 million of these 
costs recorded as regulatory liabilities within the financial statements, respectively.  

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. 

As of December 31, 2011, $195.9 million (including capitalized interest) related to this project was placed in-
service on MGE Energy's and MGE's consolidated balance sheets.

MGE Energy received notice from Elm Road Services, LLC, the project manager for the construction of the Elm 
Road Units, that the estimated total cost over-run of the units is $181 million or 8.3% over the amount initially 
approved by the PSCW, of which our share is approximately $14 million. The additional amount included the 
amounts payable to Bechtel, the builder of the Elm Road Units, pursuant to a settlement agreement entered into 
in 2009. The PSCW order approving the construction provides for recovery of excess costs of up to 5% of the 
total project, subject to a prudence review by the PSCW. Costs above the 5% cap would also be included in lease 
payments and recovered from customers if the PSCW finds that such costs were prudently incurred and were the 
result of force majeure conditions, an excused event and/or event of loss. The leases provide for a guaranteed in-
service date of September 29, 2009, for Unit 1 and September 29, 2010, for Unit 2, and imposes liquidated 
damages on ERS of $250,000 per day, of which our share is approximately $21,000 per day, for failure to 
achieve the guaranteed in-service date unless the delays result from force majeure conditions or an excused 
event. In light of the weather delays incurred on the project and other factors, we expect to request authorization 
from the PSCW to recover all costs associated with the Units and we expect the PSCW will grant relief from 
liquidated damages.  

ERS is entitled to receive $250,000 per day, of which our share is approximately $21,000 per day, from Bechtel 
under the construction contract with Bechtel for each day Bechtel failed to achieve the guaranteed in-service 
dates of September 29, 2009, and September 29, 2010, unless the delays resulted from force majeure conditions 
or an excused event. Pursuant to the terms of the 2009, settlement agreement and a change order signed 
concurrent with the turnover of Unit 2, Bechtel was granted total schedule relief of 120 days for Unit 1 and 81 
days for Unit 2. Therefore, Bechtel is responsible for 5 days of liquidated damages for Unit 1 and 23 days for 
Unit 2. All liquidated damages collected are for the benefit of our customers. Although we anticipate the PSCW 
will agree that the excused delays were caused by force majeure and other excusable conditions, there is no 
guarantee that it will grant the same schedule relief as has been granted to Bechtel. 

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

MGE. 

a.  Fair Value Measurements and Disclosures. 

In January 2010, 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. This 
authoritative guidance became effective January 1, 2010, except for the disclosures about purchases, sales, 
issuances, and settlements in the roll forward of activity in Level 3 fair value measurements, which were 
effective January 1, 2011. The authoritative guidance did not have any financial impact, but required 
additional disclosures. See Footnote 11 for additional information. 

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 will become effective 
January 1, 2012. The authoritative guidance will not have a material financial impact, but will require 
additional disclosures. 

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 will become effective January 1, 2012. The authoritative guidance 
will have an effect on our financial statement presentation of comprehensive income. 

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. This authoritative guidance will become effective January 1, 2013. The authoritative 
guidance will not have a financial impact, but will require additional disclosures.

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 is 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. 

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 other" 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.

MGE Energy and MGE 

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures 

During the fourth quarter of 2011, 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, 2011, 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, 2011, 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, 2011. As a result of that assessment, management determined that there were no 
material weaknesses as of December 31, 2011 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.

1. 

Basis of Presentation. 

MGE Energy is a holding company and conducts substantially all of its business operations through its

method. These condensed Parent Company financial statements and related notes have been prepared in 
accordance with Rule 12-04, Schedule I of Regulation S-X. These statements should be read in conjunction with 
the financial statements and the notes of the Annual Report on Form 10-K for the year ended December 31, 
2011.

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, 
2011, is estimated to be 57.3% as determined under the calculation used in the rate proceeding. MGE paid cash 
dividends of $26.6 million to MGE Energy in 2011. 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.  

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, 2011, approximately $260.2 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.
