Strong financial performance 

mge energy continues to focus on its core utility business 
and on long-term shareholder value.

our stock price, over the last 10 years, has outpaced the 
major national indices. from year end 2000 to 2010, mge 
energy stock grew 89% in part due to significant utility 
investments to help meet our customers’ energy needs.

in addition, mge energy’s three-year total return ranks 2nd 
highest in the eei index of 58 U.S. shareholder-owned electric 
utilities.  our  three-year  stock  price  appreciation,  with 
dividends reinvested, was 36.9%. a $1,000 investment in 
mge energy in 2008 would have grown to $1,370.

We also remain committed to paying dividends. in 2010, your 
Board  of  Directors  increased  the  dividend  for  the  35th 
consecutive year. our annual dividends paid per share reached 
$1.49 in 2010.

mge energy is one of only five U.S. investor-owned gas and 
electric  utilities  to  increase  dividend  payments  for  35 
consecutive years. We have been recognized as a Dividend 
achiever by mergent. in its analysis, only 7.3% of 3,700 
dividend-paying common stocks were in this elite group. 

this also was a strong year for earnings. in 2010, mge energy 
produced earnings of $2.50 per share.

earnings benefitted from an increase in electric retail sales 
volumes due to much warmer summer weather compared 
to the same period in 2009. the weather in the third quarter 
of 2010 was the warmest in recent history. the elm road 
generating Station began commercial operation in february 
2010, which also improved earnings. 

madison gas and electric (mge), our main subsidiary, has 
maintained the highest credit rating of any investor-owned 
combination utility in the nation from both Standard & poor’s 
(S&p) and from moody’s. in giving its rating, S&p cited mge’s 
“solid operational performance, a cost-conscious management 
team and a focus on a straightforward electric and gas utility 
business model.” 

in addition, mge energy’s financial performance was ranked 
among the top 40 gas and electric companies in the nation 
and as no. 1 in Wisconsin by Public Utilities Fortnightly. this 
industry journal evaluated shareholder value from 2006 to 
2009. their review also recognized our disciplined financial 
management.

Letter to Our Shareholders

MGE has an 8.33% ownership interest in the Elm Road Generating Station 
in Oak Creek. After five years of construction, the plant began energy 
production in 2010. 

cleaner, reliaBle energy 

commUnity energy griD

over the last decade, mge has steadily modernized its 
generation  fleet  to  increase  efficiencies  and  reduce  air 
emissions.  We  have  built  state-of-the-art,  coal-fired 
generating units, switched some generation from coal to 
cleaner-burning natural gas and brought more renewable 
energy online.

in 2010, we began receiving energy from the new elm road 
generating Station in oak creek. Unit 1 came online february 
2010. Unit 2 came online January 2011. emission test results 
from the elm road units show outstanding environmental 
performance.  removal  rates  for  key  pollutants  include 
nitrogen oxides, 85%; mercury, 90%; and sulfur dioxide, 97%.

electricity from this world-class plant will allow mge to stop 
burning coal at its older, less efficient Blount generating 
Station in downtown madison. earlier in 2010, we switched 
to natural gas as the primary fuel at Blount, with coal as the 
secondary fuel. We plan to stop burning all coal at Blount by 
the end of 2011.

in addition, we have increased our wind energy. We have  
12 times the wind capacity that we had in 2005. mge owns 
two wind farms and has long-term energy contracts with 
three other wind farms.

We depend on larger generation facilities to provide the bulk 
of our power. However, we also are actively taking advantage 
of the energy located in our backyards. mge owns small-
scale generation projects throughout its service area ranging 
from backup generators to solar photovoltaic panels. in 
addition, we have developed partnership programs that 
encourage customers to install renewable energy systems 
and sell the electricity back to us.

through our leadership efforts, more than 200 distributed 
energy projects throughout our community allow everyone 
to benefit from resources here at home. these local resources, 
together with our traditional power sources, form a community 
grid to meet our customers’ needs. 

tHe next generation 

technological advancements are bringing changes for all 
businesses—including utilities. at mge, we carefully test, 
evaluate and incorporate new technologies when they can 
effectively serve our customers. 

mge is taking the next step with three new technologies. 
the U.S. Department of energy is providing a $5.5 million 
grant, and mge is matching the grant to implement this 
technology. our application was one of 100 projects chosen 
from a list of nearly 400 proposals nationwide.

New, advanced electric meters are inspected by Joe Gary (left), MGE’s 
manager of Gas and Electric Measurement, and Jerry Peplinski, a senior 
engineer. MGE is installing more than 4,500 new meters. 

MGE is piloting new technology as it installs a network of 24 public  
charging stations throughout the Madison area. Owners of electric  
vehicles, such as this Chevy Volt, can plug in to recharge their cars. 

our  projects,  which  are  already  underway,  will  benefit 
customers by improving efficiency, reliability and service. 
they are:

•  new distribution grid software to upgrade our electric 
system management. the software will receive information 
from various remote sensors, diagnose disturbances and 
improve electric service restoration on our local grid.

• advanced meters with two-way communication capabilities.

•  a network of public charging stations and in-home vehicle 
charging systems for plug-in hybrid and electric vehicles. 
Time magazine has named these coulomb technologies 
charging stations one of the 50 best inventions of 2010.
the first mass-produced electric vehicles are now entering 
the U.S. market. our network of stations is part of an mge 
pilot project to study how electric vehicle charging affects 
the grid.

the charging stations serve today’s electric vehicle owners. 
But, tomorrow, they may help supply our community energy 
grid. this developing technology allows electric vehicles to 
not only draw power from the grid but to send energy back 
into the grid. Vehicle batteries may become an energy source 
for times when demand for electricity is high. this developing 
technology could help meet future needs for energy.

areas. the study evaluated 23 indicators, such as income per 
capita  and  job  growth.  the  study  noted  that  the  top 
economies have successfully weathered the recession that 
began in 2008. Money magazine also recognized madison—
naming it among the top 20 most recession-proof economies 
in the nation. 

BoarD of DirectorS

mark D. Bugher was elected to the mge energy Board of 
Directors in august 2010. as a community energy company, 
we recruit board members with strong ties to the greater 
madison area. mr. Bugher is Director of the University research

poWering oUr commUnity energy griD

mge is working hard to take advantage of local energy 
produced here in our community. We are tapping the sun, 
wind and landfill gas to create electricity that flows into the 
mix of energy resources to serve all of our customers.

over the last 10 years, we have been developing projects, 
programs and partnerships to capture resources in our own 
backyard.

through our clean power partners program, solar installations 
on customer rooftops become small energy generators within 
our larger electric grid. customers install their own photovoltaic 
systems, and then mge purchases power from those systems 
for its green pricing program.

partnering with Dane county, mge can power approximately 
4,500 homes per year from electricity produced by methane 
gas at a local landfill.

We provide backup generation for business customers who 
pay  extra  for  the  assured  supply  of  reserve  power. the 
program’s diesel generators also can help serve all customers 
by providing about 50 megawatts of power when needed  
for reliability.

mge also owns more than a dozen solar demonstration 
projects sprinkled throughout our service area as well as an 
experimental wind turbine.

the result is that we have more than 200 local energy sources 
helping produce energy here at home.

mge provides the coordination and expertise for these energy 
sources to work together safely, reliably and optimally as part 
of our community grid. We connect our locally produced 
electricity with the larger utility-scale power plants and wind 
farms. We serve our community with energy sources from 
our own backyards as well as the larger midwest region.

Next Generation > Technology

MGE is tapping new energy sources and technologies to harness 
renewable power and to better manage the power grid.

  groWing mge’S tecHnology DemonStration program 

exploring and understanding new technologies is vital for 
our future. through our technology demonstration program, 
we install and test technologies to learn how they can most 
effectively serve our customers. these technologies range 
from solar photovoltaics to geothermal systems, from urban 
wind turbines to electric vehicles. 

We site our demonstration projects in public places so we 
can educate the community about the performance of these 
new technologies and their potential role in meeting our 
energy needs.

MGE’s technology demonstration projects are located throughout the 
Madison area.

two new hybrid trucks joined the mge vehicle fleet in 2010. 
typical bucket trucks require power from an idling engine 
to operate an aerial lift. With mge’s new trucks, a hybrid 
component operates the aerial lift bucket with electricity 
from  the  battery.  a  vehicle  that  operates  its  bucket 
mechanism without idling wastes no fuel and emits no 
pollutants while the bucket is in use.

mge is evaluating the performance of these new vehicles 
by using them daily in the field. the new trucks join other 
hybrid vehicles in our fleet, including two plug-in electric

reducing the facility’s environmental footprint.

Danisco is an example of the growing sector of bio-based 
businesses  combining  Wisconsin’s  strong  agricultural 
economy with research from the University of Wisconsin- 
madison. a new midwest Biolink center is underway to help 
move bio-based research into the marketplace.

Todd Peterson is the manager of health, safety and environment at 
Danisco’s Madison facility.

Sustainability and energy efficiency were important 

considerations during a recent expansion at Danisco. 

We worked closely with MGE and made the right 

decisions for energy reliability and energy savings.

– Todd Peterson, Danisco

perched on madison’s capitol Square is a rooftop garden 
where learning, fun and solar energy production go together. 
mge installed a solar photovoltaic system on the roof of the 
new madison children’s museum. the museum, which opened 
in 2010, is a perfect location for one of our technology 
demonstration projects. While children learn about renewable 
energy at the museum, mge tracks the performance of this 
solar installation and posts it at mge.com/solar. mge provided 
funding  to  help  make  the  museum  a  model  for  energy 
efficiency and sustainable building features.

Solar panels provide energy and educational opportunities at the new 
Madison Children’s Museum. A fun feature in the rooftop garden is a chicken 
that lays eggs based on the amount of solar energy produced.

mge’s West campus cogeneration facility provides a great 
opportunity for learning. the cogeneration facility is an 
extremely efficient power plant serving the madison area 
with electricity and providing steam heating and chilled 
water air-conditioning to the University of Wisconsin-madison 
campus. more than 42,000 students attend UW-madison. 

mge  works  with  faculty  to  conduct  tours  so  university 
students can see firsthand the engineering, design and 
expertise that go into operating this natural gas-fired facility.

Madison’s Hmong community is young in comparison 

to the mainstream. Thus, MGE’s partnership to 

educate Hmong youth on ways to conserve energy 

is critical for everyone.         – Mai Zong Vue

through strong community relations and outreach, mge 
has established a successful program to provide energy 
efficiency  and  safety  information  to  madison’s  Hmong 
community. part of that educational effort is working with 
children—our next-generation of energy users. children often 
bring new ideas and information home with them—making 
learning a family affair. mge’s Hmong program is modeled 
after our other outreach efforts in the madison community. 

Mai Zong Vue visits MGE’s Web site with her  
daughter. Vue is a second-generation 
Hmong who helps advocate for the 
growing Hmong population in the 
Madison area.

learning is fun when you toss in a few tricks, jokes and some 
juggling. mge’s magicenergy® show focuses on saving 
energy, helping the environment and becoming a smart 
energy consumer. mge developed magicenergy with local 
performer Bob kann 10 years ago. mge takes the show to 
libraries, schools and other venues. the show is tailored for 
elementary and middle-school students, and we also offer 
a curriculum guide for teachers.  

MGE’s MaGicEnergy program teaches the benefits of saving energy. 
During a show at the Monona Public Library, entertainer Bob Kann shows

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 identified 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 in 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: 

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

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

  Nonregulated energy operations – constructing, owning, and leasing new electric generating capacity that will assist 
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 (ATC), a company 

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

  All Other – investing in companies and property which relate to the regulated operations, financing the regulated 

operations, or providing construction services to the other subsidiaries through its wholly owned subsidiaries MGE 
Construct, MAGAEL and CWDC, and Corporate functions. 

MGE's utility operations represent a majority of the assets, liabilities, revenues, expenses, and operations of 
MGE Energy. MGE Energy's nonregulated energy operations currently include an undivided interest in a cogeneration 
facility located on the Madison campus of the University of Wisconsin, which we refer to as the West Campus 
Cogeneration Facility and 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. 

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 and transmission line 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, 2010, 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 
2010, 2009, and 2008 were comprised of the following: 

Residential .........................................................

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

MGE is registered with two Regional Entities, The Midwest Reliability Organization and Reliability First Corporation. 
The essential purposes of these entities are: (1) the development and implementation of regional and NERC reliability 
standards, and (2) determining compliance with those standards, including enforcement mechanisms. 

Transmission 

American Transmission Company is owned by the utilities that contributed facilities or capital 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. At December 31, 2010, MGE Transco held a 3.6% 
ownership interest in ATC. 

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. In January 2009, 
MISO implemented and MGE began participating in the ancillary services market (ASM). 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 will provide the reserves for MGE's load, and MGE may offer to sell reserves from its generating 
units.  

In June 2009, MISO implemented and MGE began participating in the voluntary capacity auction. The voluntary 
capacity auction 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 to potentially obtain the necessary 
aggregate planning resource credits to meet their planning reserve margin requirement. Generator owners may 
participate to sell any excess aggregate planning resource credits that are not needed.  

PJM  
MGE is a member of PJM. PJM, an RTO, is a neutral and independent party that coordinates and directs the operation 
of the region's transmission grid, 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, that is affected by this market.  

Fuel supply and generation 

MGE satisfies its customers' electric demand with internal generation and purchased power. During the years ended 
December 31, 2010, 2009, and 2008, 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 28% (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 units decreased from approximately 47 days on December 31, 2009, to 
approximately 21 days on December 31, 2010. The co-owners' current goal is to maintain approximately a 35 day 
inventory. The inventory is expected to return to that level over the next several months, as coal inventory increases 
during scheduled annual maintenance outages.  

MGE also owns the Blount Generating Facility located in Madison, Wisconsin, which is fueled by gas, coal and other 
alternative renewable sources. In 2006, MGE announced a plan to reduce capacity at Blount from 190 MW to 100 MW 
by the end of 2011. In March 2009, MGE received notification from MISO that in order to meet national electric system 
reliability standards, MGE will need to keep Blount available at its full capacity until MISO declares that the 90 MW 
are no longer needed for system reliability. Currently, MGE estimates the reduction in capacity will occur in 2013. In 
January 2010, MGE announced it will change its primary fuel at Blount from coal to natural gas. Coal will become the 
secondary fuel at Blount. This switch to natural gas as a primary fuel occurred in March 2010. The transition from 
burning coal to burning only natural gas will still occur by the end of 2011. After the transition, the entire plant will be 
operated exclusively on natural gas. 

See discussion below under Nonregulated Operations for 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. 

See discussion above regarding gas-fired generation at Blount Generating Facility and see discussion below under 
Nonregulated Operations for 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 to meet a portion of its anticipated electric energy 
supply needs. The following table identifies purchase power commitments at December 31, 2010 with unaffiliated 
parties for the next five years.

Wind Development Rights 
During 2009, MGE Energy, through its subsidiary MAGAEL, LLC, entered into agreements 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 may 
potentially be used to develop wind farms in three counties in Iowa up to approximately 175 MWs; however, neither 
MAGAEL nor MGE Energy has any obligation to build any wind generators at these sites.  

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.

On December 31, 2010, MGE supplied natural gas service to approximately 143,000 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 2010, 2009, and 2008 were comprised of the following:

Gas operations accounted for approximately 31.5%, 36.7%, and 41.2% of MGE's total 2010, 2009, and 2008 regulated 
revenues, respectively. 

MGE can curtail gas deliveries to its interruptible customers. Approximately 14% of retail gas deliveries in 2010 and 
15% in 2009 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 5,419,478 Dth 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 include winter maximum daily quantities of: 

• 
• 

166,150 Dth (including 96,078 Dth of storage withdrawals) on ANR. 
60,108 Dth on NNG. 

Nonregulated Energy Operations 

MGE Energy, through its subsidiaries, seeks to develop generation sources that will assist MGE in meeting the 
electricity needs of its customers. Decisions on the type of energy source and its size, timing, ownership, and financing 
depend upon a number of factors including the growth of customer demand in MGE's service area and surrounding 
areas, the effectiveness of customer demand management efforts, the costs and availability of alternative power sources, 
mandates regarding renewable energy resources, the availability of transmission capacity, issues associated with siting 
power generation sources, available financing and ownership structures, regulatory treatment and recovery, construction 
lead times and risks, environmental regulations, and other factors. The decisions tend to involve long-time horizons due 
to the lead time involved in siting and constructing new generation sources and the associated transmission 
infrastructure. 

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. 

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 on February 2, 2010, and has the capacity to produce 615 MW of 
electricity. Unit 2 entered commercial operation on January 12, 2011, and has the capacity to produce 615 MW of 
electricity. Wisconsin Energy Corporation owns approximately 83% of the Elm Road Units and is the operator for those 
units. MGE Power Elm Road owns an 8.33% ownership interest in both units. Both units are used to provide electricity 
to MGE's customers. 

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

MGE Power Elm Road's estimated share of capital costs for its ownership interest in the Elm Road Units is 
approximately $180 million (excluding capitalized interest). These costs have been financed primarily through funds 
received from MGE Energy, which came from the sale of common stock (via the Stock Plan), short-term debt, and 
operating cash flows. On February 4, 2010, MGE Power Elm Road issued $50 million of 5.04% senior secured notes 
due 2040 to reimburse MGE Energy for a portion of its funds. As of December 31, 2010, $122.6 million related to this 
project was placed in-service and $55.1 million (excluding capitalized interest) related to this project is reflected in the 
construction work in progress balance on MGE Energy's and MGE's consolidated balance sheets. 

On November 1, 2005, MGE received approval from the PSCW to defer payments made to MGE Power Elm Road for 
carrying costs during construction of the facility, management fees, and community impact mitigation costs. MGE 
began collecting the carrying costs in rates in 2006. MGE estimates total carrying costs to be approximately $62.6 
million. Of these costs, $17.1 million is estimated to relate to the capitalized interest on the debt portion of the facility. 
These costs will be recognized over the period in which the facility will be depreciated. The remaining $45.5 million is 
estimated to represent the equity portion and is being recognized over the period recovered in rates. 

See Footnote 21 of Notes to Consolidated Financial Statements in Item 8. Financial Statements and Supplementary Data 
of this Form 10-K for more information regarding the Elm Road Units. 

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 installation approval of pollution controls. 

Air quality 

Air quality regulations promulgated by the EPA and 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) 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 electric generating units.

Clean Air Interstate Rule (CAIR) and the Proposed Transport Rule 
The CAIR requires NOx and SO2 emission reductions, from Midwest and eastern U.S. fossil fuel-fired electric 
generating units (EGUs) in two phases and includes a regional cap-and-trade system. The first phase began in 2009 for 
NOx and in 2010 for SO2, and contemplates reductions from 2003 levels of 55% and 40%, respectively, increasing in 
the second phase (in 2015) to 65% and 70%, respectively (from 2003 levels). MGE owns or has partial ownership in 
several generation units currently subject to the CAIR: Blount Generating Station, Columbia, the Elm Road Units, M34 
(West Marinette Combustion Turbine) and Fitchburg Combustion Turbines.  

In December 2008, the D.C. Circuit Court remanded the CAIR to the EPA for further review. In July 2010, the EPA 
introduced the proposed "Transport Rule" to replace CAIR. Similar to the CAIR, the Transport Rule is intended to 
reduce NOx and/or SO2 air emissions from fossil fuel-fired EGUs in the Midwest and eastern U.S. The proposed rule 
includes three alternative approaches to reducing emissions. Two of the proposed approaches allow limited allowance 
trading; one does not permit allowance trading. The EPA is seeking comments on these approaches. The EPA is 
targeting 2012 for implementation of the first phase of the Transport Rule. The CAIR remains in effect until the 
Transport Rule is in place. MGE anticipates that it may need to purchase NOx and SO2 allowances, install central 
equipment or implement other strategies to meet these requirements for its generation fleet. See Columbia subsection in 
Footnote 18.d for more information on the pending application to install environmental controls at Columbia. 

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, must 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.d for a discussion of 
these rules and their effects. 

Maximum Achievable Control Technologies (MACT) Standards for Hazard Air Pollutants 
In January 2010, as part of the EPA's process for developing MACT standards related to emissions of hazardous air 
pollutants for electric utilities, the EPA sent out an Information Collection Request (ICR) to hundreds of utilities across 
the United States that have coal and oil-burning EGUs. Information collected from the ICR will help the EPA develop a 
Utility MACT rule which the EPA has indicated they plan to publish by November 2011. Although we cannot predict 
the outcome of the Utility MACT Rule at this time, our coal and oil-burning EGUs may need to incur additional capital 
expenditures and install additional pollution controls to meet the Utility MACT standard(s).  

In April 2010, the EPA issued a draft MACT standard regarding hazardous air pollutant emission standards for 
industrial, commercial and institutional boilers (ICI Boiler MACT) in response to a court ruling that vacated a prior 
standard.  

Pending adoption of a final rule, the EPA has determined that case-by-case determinations be applied to all ICI boilers 
regardless of whether or not they were exempt under the vacated rule. The WDNR, following the EPA's interpretation, 
has required that all facilities with ICI boilers submit initial applications.  

MGE has boilers at Blount and Columbia classified as ICI boilers and has submitted the required initial applications to 
the WDNR. The WDNR has granted several extensions in anticipation of the EPA's ICI Boiler MACT rule being 
finalized. The latest extension granted by the WNDR lasts until March 15, 2011.  

If the boilers at Blount and Columbia are ultimately covered by the EPA ICI Boiler MACT rule when finalized, it may 
be necessary to test or limit emissions and/or install additional pollution controls. Because of the uncertainty with this 
rule at this time, we cannot predict when or if we will need additional resources or capital to comply. 

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 affect 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. However, with the 
introduction of the EPA's Transport Rule, the future of BART regulation and compliance strategies and costs is 
uncertain.  

The CAVR also requires states to submit a State Implementation Plan (SIP) that outlines how states will achieve 
reductions in visibility impairments over time. In January 2009, the EPA found Wisconsin proposed CAVR SIP 
deficient. Wisconsin has until January 2011 to submit a revised CAVR SIP. If no CAVR SIP is submitted within that 
two year period (which ends in January 2011), then the EPA must promulgate a Federal Implementation Plan (FIP) for 
the State of Wisconsin. Without a proposed CAVR implementation rule in place, it is unclear to what extent MGE's 
generation plants will be affected.  

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 United States Court of Appeals for the District of Columbia invalidated a portion of the NOx SIP Call 
concerning Wisconsin's alleged impacts on downwind, 1-hour ozone nonattainment areas. The EPA has also stated that 
portion of the NOx SIP Call concerning Wisconsin's alleged impacts on downwind 8-hour ozone nonattainment areas. If 
that 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, and WCCF. 

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 (NO2), particulate matter (PM), ozone, SO2, 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 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. See Footnote 18.d 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 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.d for additional information regarding these matters. 

Water quality 

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.d for information regarding these regulations. 

EPA Cooling Water Intake Rules (Section 316(b)) 
In 2004, the EPA promulgated final rules under Section 316(b) of the CWA addressing cooling water intake structures 
for existing large power plants. In a January 2007 court decision, significant parts of the rule were remanded to the EPA 
for further consideration. In July 2007, the EPA suspended the rule in its entirety and directed states to use their "best 
professional judgment" in evaluating intake systems. In December 2010, the EPA entered a settlement agreement which 
commits them to propose revised 316(b) rules by March 2011 and finalize requirements by June 2012. It is not known at 
this time whether and to what extent MGE's plants will be affected by this rule. 

WPDES permit – Elm Road 

Under a settlement agreement reached in July of 2008, the joint owners of Elm Road are committed to various 
environmental projects, including projects designed to address greenhouse gas emissions and water quality. MGE's 
share of those commitments involved a payment of $0.4 million for greenhouse gas reduction efforts. Additional 
payments of approximately $0.3 million, subject to regulatory approval, will be made annually over 24 years (2011-

13 

 
 
 
 
 
 
 
 
 
 
 
2034) to address water quality issues in Lake Michigan. In December 2009, the PSCW authorized recovery of the 2011 
payment to address water quality issues.  

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. As of December 31, 2009, the EPA has 
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. We will not know if additional costs exist at the 
site until cleanup is completed. At December 31, 2010, 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 the 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, that regulates 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 estimate the potential costs associated with 
the implementation of any of these initiatives at this time. 

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. 

Wisconsin Listing of Four Bat Species as Threatened in the State 
On December 8, 2010, the Wisconsin Board of Natural Resources approved modifications to existing rules to give four 
cave bat species threatened species status in Wisconsin. The cave bat threatened status designation may affect some 
MGE projects, specifically wind power projects and electric or natural gas distribution projects near wetlands. MGE 
will continue to monitor this rule and WDNR guidance that is developed to fully understand how it may affect our 
capital and operational projects. 

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. The probability 
and specific impact of such regulation cannot be reasonably estimated until final legislation and/or regulations are 
passed. MGE management would expect to seek and receive rate recovery of such compliance costs, if and when 
required. MGE will continue to monitor proposed climate change legislation and regulation. 

MGE is already addressing GHG emissions through voluntary actions. In 2005, MGE announced its Energy 2015 Plan, 
which commits to ensuring a balanced, economic energy supply with reduced environmental emissions. The Plan 
emphasizes increased renewable energy, energy efficiency and new cleaner generation – three strategies that reduce 
GHG emissions. Under MGE's Energy 2015 Plan and other actions, our CO2 emissions are currently projected to 
decline from 2005 to 2015 even though total system energy is estimated to increase. Implementation of our Energy 2015 
Plan is well underway and we are committed to achieving its goals. However, a number of factors, including but not 
limited to, changes in economic conditions, regulatory actions, customer response, energy supply issues and 
transmission delays, may require us to update and perhaps refine certain aspects of our Energy 2015 Plan accordingly. 
The cost of implementing our Energy 2015 Plan is not expected to result in any materially adverse effects on MGE's 
operations, cash flows, or financial position. Management believes that costs to implement the Energy 2015 Plan will be 
recoverable through rates.

EPA Rule on Greenhouse Gas Reporting 
In September 2009, the EPA issued its GHG mandatory reporting rule. MGE is collecting the data needed to file the 
required report on 2010 GHG emissions by March 31, 2011. Beginning on January 1, 2011 with a March 31, 2012 
reporting requirement, the EPA added sulfur hexafluoride (SF6) used in electrical transmission and GHG releases from 
natural gas transport to the reporting rule, two items that have the potential to affect MGE. MGE continues to monitor 
the EPA's evolving GHG reporting rule. 

EPA's Determination of Endangerment from Greenhouse Gases 
In December 2009, the EPA found that six GHGs, when emitted from new motor vehicles, contribute to greenhouse gas 
air pollution and endanger public health and welfare under CAA Section 202(a). This endangerment finding allowed for 
the creation of GHG emission standards from mobile sources, which were finalized by the EPA on March 31, 2010. 
This in turn paves the way for stationary source emissions of GHGs to be regulated under the CAA. See our discussion 
on the EPA's Prevention of Significant Deterioration and Title V Greenhouse Gas Tailoring Rule, and our discussion on 
the EPA's schedule to develop GHG emissions standards for utilities for additional information on how the EPA has 
begun regulating GHG emissions from stationary sources.  

EPA's Prevention of Significant Deterioration and Title V Greenhouse Gas Tailoring Rule 
On May 13, 2010, the EPA released its Greenhouse Gas "Tailoring Rule" to address the regulation of stationary sources 
for GHG emissions. Through this Tailoring Rule, the regulation of GHGs will be accomplished using the EPA's two 
principal stationary source CAA permitting programs: the pre-construction permitting Prevention of Significant 
Deterioration (PSD) program and the operations permitting (Title V) program.  

Beginning in January 2011,the EPA's Tailoring Rule has been designed to "phase in" facilities subject to PSD or Title V 
permitting (i.e. new facilities and existing facilities with certain qualifying modifications). Under the Tailoring Rule, it 
is understood that PSD requirements for covered new or modified sources include the requirement that a plant 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 also 
agreed to take final action on both of these by May 26, 2012. As part of this notice, the EPA has not indicated at what 
level emissions standards will be set. 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. 

Proposed Climate Change Legislation 

Federal Actions on Climate Change 
The 111th Congress ended without enactment of comprehensive climate change legislation in spite of significant 
activity. The U.S. House of Representatives in the 112th Congress has introduced several bills related to GHG regulation 
including bills to prevent the EPA from receiving funding for a cap-and-trade program for greenhouse gases as well as 
bills to prevent or delay the EPA's regulation of GHGs under the current Clean Air Act. 

State and Regional Actions on Climate Change 
Wisconsin Governor Doyle's Global Warming Task Force issued a July 2008 report with numerous recommendations to 
address GHG emissions. MGE participated as an active member of the Task Force. Several PSCW proceedings were 
commenced as a result of Task Force recommendations. Many of the recommendations made by the Task Force were 
included in state legislation in early 2010, but no legislation was enacted. It is unlikely the Wisconsin Senate or 
Assembly will push for broad GHG regulation in 2011. 

In addition, in November 2007, Wisconsin, along with Illinois, Iowa, Kansas, Michigan, Minnesota, and Manitoba, 
Canada signed on to the Midwestern GHG Accord – an accord designed to develop a Midwestern GHG reduction 
program. The Advisory Group recommended numerous regional actions be taken to help reduce GHGs. Wisconsin has 
not developed rules or legislation to implement these recommendations.

Employees 

As of December 31, 2010, MGE had 701 employees. MGE employs 222 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. 

16 

 
 
 
 
 
 
 
 
 
 
 
 
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 be required to make a refund to 
customers if the fuel rules costs fall outside the lower end of the range and would be allowed to request a surcharge if 
the fuel rules costs exceeded the upper end of the range. The range is defined by the PSCW and is currently plus or 
minus 2%. MGE assumes the risks and benefits of variances that are within the bandwidth.  

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 projects, 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, particularly with regard to enforcement efforts focused on power plant emissions obligations. These 
effects can be seen not only with respect to new construction, such as our participation in the Elm Road generating 
units, but could also require the installation of additional control equipment or other compliance measures such as 
altered operating conditions at existing facilities such as Columbia or Blount. 

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, if adopted, legislative and regulatory GHG initiatives 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 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, 

17 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  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. 

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. 

Our financial performance depends on the equipment and facilities in our distribution system being operational. 

Weather conditions, accidents, catastrophic events, and failures of equipment or facilities can disrupt or limit our ability 
to deliver electricity and gas. Efforts to repair or replace equipment and facilities may not be successful, or we may be 
unable to make the necessary improvements to our distribution system, causing service interruptions. The resulting 
interruption of services could result in lost revenues and additional costs. 

We face construction risk in connection with the completion of generating units. 

We have assumed risks under the agreements related to our ownership interest in two 615 MW coal-fired generating 
units in Oak Creek, Wisconsin. If the units' final construction costs exceed the fixed costs allowed in the PSCW order, 
this excess will not be recoverable from MGE or its customers unless specifically allowed by the PSCW. Any Oak 
Creek project costs above the authorized amount will be subject to a prudence determination made by the PSCW. 

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. MGE Energy had $22.5 million of variable-rate debt 
outstanding at December 31, 2010, including $3.5 million for MGE. 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. Also, interest rates affect discount rates which are a key assumption for our defined benefit pension 
plans and may impact the amount of expense and timing of contributions to the plan.  

Market performance affects our employee benefit plan asset values. 

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 may affect our ability to finance at a reasonable cost and in accordance with 
our planned schedule. 

The credit markets have experienced some recent disruption and uncertainty. 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.  

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.

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

(4) On January 19, 2006, MGE announced that it would cease coal-fired generation at Blount in 2011, subject to 
certain conditions, including regulatory approvals. In March 2010, natural gas became the primary fuel and coal 
became the secondary fuel. 

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

(6) MGE's 8.33% share in each of two 615 MW coal-fired generating units. MGE leases the electric generating assets 
owned by MGE Power Elm Road. Unit 1 entered commercial operation in February 2010. Amounts shown represent 
MGE's share of the net summer rated capacity of Unit 1. Unit 2 entered commercial operation in January 2011. 

(7) Three facilities are owned by MGE and three facilities are leased. 

(8) These facilities are owned by MGE. 

(9) Nameplate capacity rating is 11 MW. 

(10) Nameplate capacity rating is 30 MW.

Gas facilities include 2,547 miles of distribution mains, which are owned by MGE. 

A significant portion of MGE's electric and gas distribution facilities is 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, 2010, there were $1.2 million of first mortgage bonds outstanding. See Footnote 9 for additional 
information regarding MGE's first mortgage bonds. 

MGE Power West Campus has collaterally assigned its right to lease payments from MGE for the WCCF in order to 
secure the repayment of $50 million of senior secured notes issued by MGE Power West Campus. See Footnote 9 for 
additional information regarding these senior notes. 

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 $50 million of senior secured notes issued by MGE Power Elm Road. See Footnote 9 for

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 $28.8 million plus dividends on 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, 2010, is estimated to be 58.5% as determined under the 
calculation used in the rate proceeding. MGE paid cash dividends of $26.2 million to MGE Energy in 2010.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 West 
Campus and MGE Power Elm Road, 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, 
2010, approximately $248.6 million was available for the payment of dividends under this covenant.

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

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

General 

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

  Electric utility operations, conducted through MGE, 
  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 as well as certain construction 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 143,000 customers in the Wisconsin counties of Columbia, Crawford, Dane, 
Iowa, Juneau, Monroe, and Vernon. 

Our nonregulated energy operations own interests in new 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 partial ownership of a cogeneration 
project on the UW-Madison campus and an undivided 8.33% ownership interest in two 615 MW coal-fired generating 
units in Oak Creek, Wisconsin, one of which entered commercial operation on February 2, 2010 and the other of which 
entered commercial operation on January 12, 2011. MGE operates the cogeneration project, and a third party operates 
the units in Oak Creek. 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 plans to meet 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, 
  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 pending environmental rule changes, 

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

For the year ended December 31, 2010, MGE Energy's earnings were $57.7 million or $2.50 per share compared to 
$51.0 million or $2.21 per share for the same period in the prior year. MGE's earnings for the year ended December 31, 
2010, were $37.7 million compared to $35.9 million for the same period in the prior year.

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

  A 10.0% increase in retail electric revenues reflecting 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 (a 

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

March 2010.  

  Higher nonregulated energy revenues are attributable to Elm Road Unit 1 entering commercial operation in 

February 2010.  

Our net income during 2009 compared to 2008 primarily reflects the effects of the following factors: 

  A 3.9% decrease in electric revenue, reflecting lower customer demand primarily as a result of cooler-than-normal 
summer weather. According to the National Weather Service, July 2009 was the coolest on record in Madison, 
where MGE's primary service territory resides. Cooling degree days (a measure for determining the impact of 
weather during the cooling season) for 2009 decreased by 32% compared to 2008. Reduced economic activity also 
contributed to the reduced demand for service. 

  Retail gas sales were relatively flat compared to the prior year. In 2008, the gas utility had expensed a $1.3 million 
settlement (excludes premium) associated with a weather hedge (heating degree collar) as a result of colder-than-
normal weather. The gas utility had no weather hedges during 2009.  

  Higher nonregulated energy revenues primarily attributable to higher carrying costs being recognized for the Elm 
Road Units. Carrying costs during construction of the nonregulated energy projects, related to the equity portion, 
are recognized over the period of time the costs are recovered in rates.  

  A $0.6 million increase in earnings from our interest in ATC. 

  A decline in the All Other segment is primarily attributable to gains on sales of investments recognized in the year 

ended December 31, 2008. 

During 2010, the following events occurred: 

Elm Road Units: Elm Road Unit 1 entered commercial operation on February 2, 2010. On February 4, 2010, our 
subsidiary, MGE Power Elm Road, which owns an ownership interest in those Units, issued $50 million of its 5.04% 
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.  

ATC: MGE Transco contributed $0.7 million for voluntary capital contributions to ATC for the year ended 
December 31, 2010.

Smart Grid Investment Grant: MGE has been approved 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 proposed projects to more than $11 million. The proposed projects will install 
technologies to boost efficiency, enhance service and improve reliability for customers. The stimulus grant will help 
fund the following projects: advanced metering infrastructure, plug-in hybrid electric vehicles support, and distribution 
management. As of December 31, 2010, MGE has spent $2.5 million related to these projects. 

During 2011, several items may affect us, including: 

2011 Rate Filing: In January 2011, the PSCW authorized MGE to increase 2011 rates for retail electric customers by 
2.3% and increase rates for gas customers by 1.0%. The increase in retail electric rates was primarily driven by costs for 
MGE's share of the Elm Road Units.  

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 million 
for MGE Energy (including MGE) and $75 million for MGE to address our liquidity needs. 

Elm Road Unit: Elm Road Unit 2 entered commercial operation on January 12, 2011. 

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 the 
costs of owning and operating fossil-fueled generating plants, such as Columbia and Elm Road Unit 1, from which we 
derive approximately 34% 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 activities previously undertaken 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. 

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

(5.4) 
28.4  

  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. 

Electric fuel and purchased power 

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: 

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

6.2  
4.9  
3.4  
1.4  
15.9  

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.

 

 

Gas costs/rates. The average retail rate per therm for the year ended December 31, 2010, decreased 4.5% 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, is 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, is 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 $11.3 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

  Volume. During the year ended December 31, 2009, there was a 4% decrease in total retail sales volumes when 

compared to the same period in the prior year, as a result of cooler-than-normal weather. The demand for electricity 
is affected by weather conditions. According to the National Weather Service, July 2009 was the coolest on record in 
Madison, where MGE's primary service territory resides. Cooling degree days for 2009 decreased by 32% compared 
to 2008. Reduced economic activity also contributed to the reduced demand for service. 

  Rates changes. Rates charged to retail customers for the year ended December 31, 2009, were 2.1% or $7.6 million 

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

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 from 2008. The decrease in retail electric rates is driven by a decrease 
in fuel and purchased power costs, a 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 currently included in rates. 

As a result of lower than expected fuel and purchased power costs in 2008, a fuel refund was approved by the 
PSCW. In March 2009, the PSCW completed their audit of 2008 electric fuel costs and issued a final order 
approving the amount to be refunded to customers. A refund of $5.7 million (includes interest) was applied to 
customers' accounts in March 2009. See "Other revenues" discussion below for more information on this refund. 

In May 2009, the PSCW approved an interim order authorizing MGE to implement a credit of $0.00204 per kWh, 
due to a decrease in actual electric fuel costs, when compared to those fuel costs projected in MGE's most recent 
rate order. During the year ended December 31, 2009, $4.1 million had been credited to electric customers. See 
"Other revenues" discussion below for more information on this interim order. 

In 2008, the PSCW approved a $0.00239 per kWh interim fuel surcharge subject to refund, with interest, on MGE's 
electric rates to cover increased fuel and purchased power expenses. For the year ended December 31, 2008, this 
interim surcharge resulted in a $5.1 million increase to electric rates. See "Other revenues" below for additional 
information on this interim fuel surcharge. 

 

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, 2009, sales to the market decreased $3.2 million 
when compared to the same period in the prior year, reflecting decreased opportunities for sales.  

  Other revenues. Other electric revenues increased $11.0 million for the year ended December 31, 2009, compared 

to the same period in the prior year. 

As a result of the refund provision in the May 2008 interim fuel surcharge order, MGE recognized an estimated 
refund to customers totaling $5.5 million during the year ended December 31, 2008, and reflected this reduction in 
other electric revenues. During the year ended December 31, 2009, MGE recorded $5.5 million in other electric 
revenues to offset the impact of the 2008 fuel refund. 

Also included in other revenues for the year ended December 31, 2009, is a $0.3 million projected refund which 
was accrued related to the May 2009 interim order.

Other electric revenues reflect 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 $10.7 million and $11.0 million for the years ended 
December 31, 2009 and 2008, respectively. 

Electric fuel and purchased power 

As a result of more favorable prices for purchased power as compared to internal generation, power purchases were 
increased, and internal generation reduced, causing fuel for electric generation to decrease and purchased power 
expense to increase. 

The expense for fuel for electric generation decreased $17.9 million or 32.6% during the year ended December 31, 
2009, compared to the same period in the prior year. This decrease in expense reflects a $12.8 million decrease related 
to the lower electric generation and a $5.1 million decrease related to fuel cost. 

Purchased power expense increased by $10.4 million or 14.0% during the year ended December 31, 2009, compared to 
the same period in the prior year. This increase in expense reflects an $18.2 million or 27.3% increase in the volume of 
power purchased offset by a $7.8 million or 10.5% decrease in the per-unit cost of purchased power.  

Electric operating and maintenance expenses 

Electric operating and maintenance expenses decreased $4.6 million during the year ended December 31, 2009, 
compared to the same period in 2008. The following changes contributed to the net change:

For the year ended December 31, 2009, production costs and maintenance costs decreased due to lower internal 
generation, compared to the same period in the prior year. In addition, customer accounts costs decreased due to lower 
uncollectible accounts expense. Transmission costs increased primarily due to network service fees pertaining to ATC. 

Electric depreciation expense 

Electric depreciation expense increased $1.4 million for the year ended December 31, 2009, compared to the same 
period in the prior year as a result of additional electric plant assets.

 

 

Gas costs/rates. The average retail rate per therm for the year ended December 31, 2009, decreased 20.9% 
compared to the same period in 2008. The primary contributor to this decrease is significantly lower natural gas 
costs.  

Transportation and other revenues. Transportation and other revenues decreased a total of $0.7 million primarily 
due to a decrease in income realized under the GCIM. 

Under MGE's GCIM, 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 and 2008, shareholders 
received the benefit of $1.9 million and $2.4 million, respectively, from capacity release revenues and commodity 
savings under the GCIM. 

Cost of gas sold 

For the year ended December 31, 2009, cost of gas sold decreased by $48.5 million, compared to the same period in the 
prior year. The cost per therm of natural gas decreased 27.6%, which resulted in $46.9 million of reduced expense. In 
addition, a 0.9% decrease in the volume of gas purchased resulted in $1.6 million less expense.  

Gas operating and maintenance expenses 

Gas operating and maintenance expenses decreased $1.7 million for the year ended December 31, 2009, compared to 
the same period a year ago. The following changes contributed to the net change.

Customer accounts costs decreased due to lower uncollectible accounts expense. 

Gas depreciation expense 

Gas depreciation expense increased $0.4 million for the year ended December 31, 2009, compared to the same period in 
the prior year as a result of additional gas plant assets. 

Other Income (deductions), Net 

Other income, net for the gas and electric segments increased $1.6 million for the year ended December 31, 2009, 
compared to the same period in the prior year. In 2008, the gas utility had expensed a $1.5 million settlement (includes 
premium) associated with a weather hedge (heating degree collar) as a result of colder-than-normal weather. The gas 
utility had no weather hedges during 2009. In addition, charitable contributions decreased by $1.5 million for the year 
ended December 31, 2009, compared to the prior year. Offsetting this change is a $0.8 million pretax gain on 
investments recognized in 2008 and a $0.4 million reduction in AFUDC-equity for the year ended December 31, 2009, 
compared to the prior year.

Nonregulated Energy Operations - MGE Energy and MGE 

Nonregulated energy operating revenues 

Operating revenues from nonregulated energy operations increased $1.7 million for the year ended December 31, 2009, 
when compared to the same period in the prior year. Operating revenues from nonregulated energy operations for both 
the year ended December 31, 2009 and 2008, include $14.9 million in interdepartmental revenues related to a leasing 
arrangement between MGE and MGE Power West Campus. Upon consolidation, these interdepartmental revenues are 
eliminated.  

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 $59.5 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 year ended December 31, 2009 and 2008, MGE 
Power Elm Road recognized $8.1 million and $6.4 million, respectively, related to carrying costs on the Elm Road 
Units.  

Nonregulated energy interest expense, net 

For the year ended December 31, 2009 and 2008, interest expense, net at the nonregulated energy operations segment 
was $2.7 million and $2.6 million, respectively. Interest expense at the nonregulated energy segment for both the year 
ended December 31, 2009 and 2008, includes $2.8 million in interest expense incurred on $50 million of long-term, 
fixed-rate borrowings at MGE Power West Campus. 

Also included in the nonregulated interest expense is interdepartmental interest expense and capitalized interest at MGE 
Power Elm Road. During the year ended December 31, 2009 and 2008, MGE Power Elm Road was charged 
$3.4 million and $4.8 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 by $3.4 million and $4.8 million, respectively, in capitalized interest.  

During the year ended December 31, 2009 and 2008, MGE Power Elm Road recorded $0.1 million in interest income 
on cash advanced to ERS for construction of transmission equipment and work done by ATC related to the Elm Road 
Units. 

Transmission Investment Operations - MGE Energy and MGE 

Transmission investment other income 

For the year ended December 31, 2009 and 2008, other income at the transmission investment segment was $8.2 million 
and $7.2 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 - other income 

Other income in the all other segment decreased $2.4 million for the year ended December 31, 2009, compared to the 
same period in the prior year primarily due to a $2.5 million pretax gain on investments recognized in the prior year.  

All other interest income, net 

All other interest income, net for the year ended December 31, 2009 and 2008, was $2.8 million. 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. Interest income for the year ended 
December 31, 2008, represents $4.8 million in interdepartmental interest income from MGE Power Elm Road, partially 
offset by $2.0 million in interest expense on short-term debt. The interdepartmental interest income is eliminated upon 
consolidation.

Consolidated Other General Taxes 

MGE Energy's and MGE's other general taxes increased $1.1 million or 6.3% for the year ended December 31, 2009, 
when compared to the same period in 2008, 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 increased. 

Consolidated Income Taxes 

MGE Energy's effective income tax rate for the year ended December 31, 2009, is 35.6% compared to 35.5% for the 
same period in 2008. MGE's effective income tax rate for the year ended December 31, 2009, is 35.4% compared to 
35.2% for the same period in the prior year. The effective income tax rate differences for both MGE Energy and MGE 
for 2009 compared to 2008 are insignificant, as the effective income tax rate components are substantially equivalent. 

Under 2009 Wisconsin Act 2, effective for years beginning on or after January 1, 2009, Wisconsin requires corporations 
to use combined reporting to compute their Wisconsin income for income tax purposes. Formerly, Wisconsin law 
required each corporation in a combined group to file separate returns. The combined reporting statute in Wisconsin did 
not have a significant impact on the effective income tax rates of MGE Energy and MGE. 

For 2009 tax return purposes, MGE Energy and MGE changed its income tax methods of accounting for repairs based 
on current Treasury Regulations and case law. The change in income tax methods of accounting involves, among other 
things, identification of appropriate units of property for repair work and computation of a cumulative one-time tax 
deduction able to be claimed in 2009. The effect on the 2009 financial statements of the cumulative adjustment is an 
increase to deferred tax expense and a corresponding decrease in the current tax provision in the amount of about 
$9.2 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 

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, 2009, MGE Energy (through its wholly owned subsidiary MGE Power) 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 earned $1.5 million, net of tax, for its interest in MGE Transco. These amounts 
are recorded as noncontrolling interest expense, net of tax, on MGE's consolidated statement of income. 

For the year ended December 31, 2008, MGE Energy (through its wholly owned subsidiary MGE Power) had earned 
$7.6 million and $3.9 million, net of tax, for its interest in MGE Power West Campus and MGE Power Elm Road, 
respectively. Additionally, MGE Energy had earned $0.8 million, net of tax, for its interest in MGE Transco. These 
amounts are recorded as noncontrolling interest expense, 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.  

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. 

MGE Energy's net income increased $6.7 million for the year ended December 31, 2010, when compared to the same 
period in the prior year. 

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. Working capital accounts resulted in $12.6 
million in cash provided by operating activities for the year ended December 31, 2009, primarily due to decreased 
receivables, decreased inventories (due to lower natural gas costs), and decreased unbilled revenues, partially offset by 
decreased accounts payable. 

The cash flows for the year ended December 31, 2010, reflect a $7.7 million benefit of lower taxes payable, compared 
to the same period in the prior year, primarily due to the additional benefit from the finalization of the income tax 
method change in accounting for electric repairs.  

Pension contribution resulted in an additional $1.6 million in cash used by operating activities for the year ended 
December 31, 2010, 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 contributed $8.9 million of operating cash inflows for the year ended 
December 31, 2010, compared to $0.6 million in the prior year. This increase 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. Any 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. 

2009 vs. 2008 

Cash provided by operating activities for the year ended December 31, 2009, was $117.9 million, an increase of 
$43.2 million when compared to the same period in the prior year, primarily due to working capital changes. 

Working capital accounts resulted in $12.6 million in cash provided by operating activities for the year ended 
December 31, 2009, compared to $32.2 million in cash used for operating activities during the same period in the prior 
year. The increase in cash provided by working capital accounts is primarily attributable to decreased inventory (due to 
lower natural gas costs), lower accounts receivable (due to lower sales and commodity costs), and reduced collateral 
postings in the derivative portfolio. 

MGE Energy's net income decreased $1.8 million for the year ended December 31, 2009, when compared to the same 
period in the prior year. 

Cash flows related to tax effects increased $9.1 million for the year ended December 31, 2009, compared to the year 
ended December 31, 2008, primarily due to tax depreciation differences associated with bonus depreciation and the 
income tax method change in accounting for repairs.  

Pension contribution resulted in an additional $7.6 million in cash used by operating activities for the year ended 
December 31, 2009, when compared to the same period in the prior year. These contributions were made to comply 
with the ERISA and the Pension Protection Act of 2006, and additional contributions were at management's discretion.

2010 vs. 2009 

Cash provided by operating activities for the year ended December 31, 2010, was $115.2 million, a decrease of 
$6.1 million when compared to the same period in the prior year, primarily due to working capital changes.  

Net income increased $8.7 million for the year ended December 31, 2010, when compared to the same period in the 
prior year. 

Working capital accounts resulted in $10.9 million in cash used by operating activities for the year ended December 31, 
2010, primarily due to increased receivables, increased prepaid taxes (a result of a tax method change in accounting for 
repairs), and decreased payables, partially offset by decreased inventories. Working capital accounts resulted in 
$17.8 million in cash provided by operating activities for the year ended December 31, 2009, primarily due to decreased 
receivables, decreased inventories (due to lower natural gas costs), and decreased unbilled revenues, partially offset by 
decreased accounts payable. 

The cash flows for the year ended December 31, 2010, reflect a $7.8 million benefit of lower taxes payable, compared 
to the same period in the prior year, primarily due to the additional benefit from the finalization of the income tax 
method change in accounting for electric repairs. 

Pension contribution resulted in an additional $1.6 million in cash used by operating activities for the year ended 
December 31, 2010, when compared to the same period in the prior year. These contributions were made to comply 
with the ERISA and the Pension Protection Act of 2006, and additional contributions were at management's discretion.

Capital Requirements and Investing Activities  

MGE Energy 

2010 vs. 2009 

MGE Energy's cash used for investing activities decreased $22.6 million for the year ended December 31, 2010, when 
compared to the same period in the prior year.  

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.  

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.  

2009 vs. 2008

Capital expenditures for the year ended December 31, 2009, were $77.9 million. This amount represents a $27.8 million 
decrease from the expenditures made in the same period in the prior year. This decrease is related to lower construction 
activity of $22.8 million related to the Elm Road Units and a $7.8 million decrease of capital expenditures due to the 
completion in February 2008 of the Top of Iowa III wind generation project. These decreases were partially offset by an 
increase of $3.1 million in other utility capital expenditures.  

During the year ended December 31, 2009, MGE Energy received cash proceeds from the sale of equity investments of 
$0.1 million compared to the $3.6 million received for the same period in the prior year.

decrease from the expenditures made in the same period in the prior year. This decrease is related to lower construction 
activity of $22.8 million related to the Elm Road Units and a $7.8 million decrease of capital expenditures due to the 
completion in February 2008 of the Top of Iowa III wind generation project. These decreases were partially offset by an 
increase of $3.1 million in other utility capital expenditures.

MGE Energy intends to fund any remaining capital commitments for the Elm Road Units with funds generated from 
normal operations, the issuance of long-term debt, and short-term debt. 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. Based upon an oral 
understanding with a prospective note purchaser, which is subject to the completion and execution of definitive 
agreements, MGE Power Elm Road expects to issue an additional $30 million of 4.74% senior secured notes due 2041 
in the first quarter of 2011. The proceeds from this additional financing are expected to be used to payoff the 
outstanding bank loans under MGE Energy's line of credit, which were used as short-term financing during the 
construction of Elm Road. MGE Energy's major 2010 capital projects included the Elm Road Units. During 2010, 
$12.4 million in capital expenditures were incurred for the construction of the Elm Road Units. Included in this amount 
is $2.7 million of interest capitalized.  

As of December 31, 2010, MGE Power Elm Road's remaining capital commitments for the Elm Road Units are 
estimated to be $2.2 million in 2011. See Footnote 21a for additional information. 

MGE Energy used funds received as dividend payments from MGE Power West Campus as well as short and long-term 
external financing to meet its 2010 capital requirements and cash obligations, including dividend payments. External 
financing included short-term financing under existing lines of credit and proceeds from equity issued under the Stock 
Plan.  

Financing Activities 

MGE Energy 

2010 vs. 2009 

Cash used for MGE Energy's financing activities was $64.2 million for the year ended December 31, 2010, compared to 
$37.3 million of cash used for the year ended December 31, 2009. 

MGE Energy received $6.3 million in cash proceeds as the result of stock issued pursuant to the Stock Plan during the 
year ended December 31, 2009.

shares. All MGE Energy common stock shares under the Stock Plan are sold pursuant to a registration statement that 
has been filed with the SEC and is currently effective.  

For the year ended December 31, 2010, dividends paid were $34.4 million compared to $33.7 million in the prior year. 
This increase was a result of higher dividend per share ($1.49 vs. $1.46). 

For the year ended December 31, 2010, MGE Energy repaid $16.5 million of long-term debt and issued $80.0 million of 
long-term debt, including the issuance of $50 million of senior secured notes by MGE Power Elm Road, the proceeds of 
which were used to repay short-term debt. 

For the year ended December 31, 2010, net short-term debt repayments were $92.0 million compared to $60.0 million 
for the same period in the prior year.

During the year ended December 31, 2010, cash used for MGE's financing activities was $55.7 million compared to 
$41.8 million of cash used by MGE's financing activities in the prior year.  

Dividends paid from MGE to MGE Energy were $26.2 million for the year ended December 31, 2010 compared to 
$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

dividends were paid from MGE to MGE Energy for the year ended December 31, 2008. 

Equity contributions received by noncontrolling interest decreased $34.0 million as a result of MGE Power Elm Road 
requiring less funding for construction of property, plant and equipment. This decrease is slightly offset by $4.2 million 
of affiliate financing on the Elm Road Units received in the year ended December 31, 2009.

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 $28.8 million and $31.4 million for 2010 and 2009, 
respectively, plus dividends on 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, 2010 and 
2009, is estimated to be 58.5% and 57.5%, respectively, as determined under the calculation used in the rate proceeding. 
MGE was not restricted from paying cash dividends in 2010. Cash dividends paid to MGE Energy were reduced in 
2009 in order to build additional common stock equity in MGE. Cash dividends of $26.2 million and $19.3 million were 
paid to MGE Energy in 2010 and 2009, 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 West Campus and MGE Power Elm Road, 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, 
2010, approximately $248.6 million was available for the payment of dividends under this covenant. 

Credit Facilities 

At December 31, 2010, MGE Energy and MGE had the following aggregate bank commitments and available capacity

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 1.25%.  

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 West Campus and MGE Power Elm 
Road. At December 31, 2010, the ratio of consolidated debt to consolidated total capitalization for each of MGE Energy 
and MGE were 40.6% and 37.3%, respectively. See Footnote 10, for additional information regarding the credit 
facilities.

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

mandatory repurchase date. The actual maturity date for these IRB's is October 1, 2027. 

The above amounts do not include any contributions for MGE's pension and postretirement plans. Contributions to the 
plans for 2011 are expected to be approximately $21 million and for 2012 through 2015 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. 

The above amounts, also, do not include future voluntary capital calls to ATC. On January 31, 2011, MGE Transco 
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, 2010, 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 2013. At December 31, 2010, MGE Energy had 
borrowed $19.0 million under this credit facility. Accordingly, MGE Energy's available credit under this credit facility 
was $21.0 million at December 31, 2010. 

(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) Amounts include a $75.0 million committed revolving credit agreement expiring in July 2013. This credit facility is 
used to support commercial paper issuances. At December 31, 2010, there were no borrowings under this facility. At 
December 31, 2010, there was $3.5 million of commercial paper outstanding. 

Blount Station 

In 2006, MGE announced a plan, subject to certain conditions, that includes discontinuing coal use by the end of 2011 
at Blount. The original plan contemplated that the plant would continue to run on natural gas but would be reduced from 
its current approximate 190 MW capacity to 100 MW when coal burning is discontinued. MGE determined that certain 
employee positions would be eliminated as a result of this exit plan.  

In March 2009, MGE received notification from MISO that in order to meet national electric system reliability 
standards, MGE will need to keep Blount available at full capacity until MISO declares that the 90 MW are no longer 
needed for system reliability. To comply with the MISO directive, MGE will delay plans for retiring 90 MW of 
generation equipment at Blount. The transition from burning coal to burning only natural gas will still occur by the end

of 2011. After 2011, the entire plant will be operated exclusively on natural gas. MGE is working with MISO to develop 
a detailed agreement for this continued operation, which among other things will include a mechanism for cost 
recovery.  

In January 2010, MGE announced it will change its primary fuel at Blount from coal to natural gas. Coal will become 
the secondary fuel at Blount. This switch to natural gas as a primary fuel occurred in March 2010. As a result of this 
change, certain employee positions were eliminated and severance benefits in 2010 totaled $0.5 million. These 
severance benefits were accelerated into 2010 from 2011, but were offset by lower payroll charges in 2010. 

MGE has entered into agreements providing severance benefits to employees affected by the exit plan. Estimated 
benefits expected to be paid are as follows: $0.3 million in 2012 and $0.3 million in 2013. MGE will recover in rates the 
costs associated with the capacity reduction at Blount. As such, the severance charges, in 2012 and 2013, for these 
employees have been deferred and recognized on the consolidated balance sheet of MGE Energy and MGE as a 
regulatory asset. 

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. Actual results may differ from these estimates 
under different assumptions or conditions. We believe the following critical accounting estimates affect our more 
significant judgments used in the preparation of our consolidated financial statements. 

Unbilled Revenues 

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

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

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

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

delivered to customers. 

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

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

Allowance for Doubtful Accounts 

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

47 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
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.  

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 2010, MGE used an assumed return on assets of 8.50% for pension and 7.39% for other 
postretirement benefits. In 2011, MGE will lower the return on asset assumption from 8.50% to 8.25% for pension. 
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 $1.4 million, before taxes. 

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

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

charges. 

See Footnote 13 for additional discussion of these plans. 

Income Tax Provision 

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

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

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

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

Accounting for Derivative Instruments 

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

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

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. 

Asset Retirement Obligation 

The ability to reasonably estimate an asset retirement obligation (ARO) is a matter of management judgment, based 
upon management's ability to estimate a settlement date or range of settlement dates and a method or potential method 
of settlement of its AROs. In determining whether our AROs could be reasonably estimated, management considers 
past practices, industry practices, management's intent, and the estimated economic life of the assets. The fair value of 
the AROs is then estimated using an expected present value technique. Changes in management's assumptions regarding 
settlement dates, settlement methods, or assigned probabilities could have a material effect on the liability recorded at 
December 31, 2010, as well as the regulatory asset recorded. The liabilities associated with AROs will be adjusted on an 
ongoing basis due to the passage of time and revisions to either the timing or the amount of the original estimates of 
undiscounted cash flows. These adjustments could have a significant impact on the consolidated balance sheets. See 
Footnote 20 of the Notes to Consolidated Financial Statements for more information regarding AROs. 

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

See Footnote 22 for discussion of new accounting pronouncements. 

Item 7A. Quantitative and Qualitative Disclosures About Market Risk 

MGE Energy and MGE are potentially exposed to market risk associated with interest rates, commodity prices, weather, 
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.  

49 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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.  

Under the electric fuel rules, MGE would be required to make a refund to customers if the fuel rules costs fall outside 
the lower end of the range and would be allowed to request a surcharge if the fuel rules costs exceeded the upper end of 
the range. 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 bandwidth. For 2010, fuel and purchased power costs included in MGE's base fuel rates 
are $102.0 million. See Footnote 17 for additional information. 

The PSCW approved new fuel rules on December 27, 2010, to be 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 its electric retail customers.  

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, subject to certain limited incentives.  

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 is two 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, 2010, the cost basis of these 
instruments exceeded their fair value by $0.2 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 which 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 the option to 
purchase power during a period of time preceding the base term as well as 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, 2010, reflects a loss position of $19.0 million. 

Interest Rate Risk 

Both MGE Energy and MGE have short term borrowings at varying interest rates. MGE issues commercial paper for its 
short-term borrowings, while MGE Energy draws from its current credit facility to meet its short-term borrowing needs 
(see Footnote 10 of the Notes to Consolidated Financial Statements). Borrowing levels vary from period to period 
depending upon capital investments and other factors. Future short-term interest expense and payments will reflect both 
future short-term interest rates and borrowing levels. MGE Energy and MGE manage interest rate risk by limiting their 
variable rate exposure and continually monitoring the effects of market changes on interest rates. MGE is not exposed to 
changes in interest rates on a substantial portion of its long-term debt until that debt matures and is refinanced at market 
rates. Assuming the current level of variable rate borrowings and assuming a 1% change in the 2010 average interest 
rate under these borrowings, it is estimated that our 2010 interest expense and net income would have changed by 
$0.2 million for MGE Energy and less than $0.1 million for MGE. 

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 $1.4 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 11.0% during the year 
ended December 31, 2010. During the year ending December 31, 2009, the value of our employee benefit plans trusts' 
assets increased by approximately 23.9%. 

50 

 
 
 
  
 
 
 
 
 
 
 
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, 2010, 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, 2010, 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, 
2010 and 2009, and the results of their operations and their cash flows for each of the three years in the period ended 
December 31, 2010, 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, 2010, 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.

Report of Independent Registered Public Accounting Firm 

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

In our opinion, the accompanying consolidated balance sheets and the related consolidated financial statements listed in 
the index appearing under Item 15(a)(1) present fairly, in all material respects, the financial position of Madison Gas 
and Electric Company and its subsidiaries at December 31, 2010 and 2009, and the results of their operations and their 
cash flows for each of the three years in the period ended December 31, 2010, in conformity with accounting principles 
generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in 
the index appearing under Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when 
read in conjunction with the related consolidated financial statements. These financial statements and financial 
statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on 
these financial statements and financial statement schedule based on our audits. We conducted our audits of these 
statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those 
standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial 
statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the 
amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates 
made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion.

Notes to Consolidated Financial Statements 
December 31, 2010, 2009, and 2008 

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 West Campus and MGE Power Elm Road. MGE Power and its 
subsidiaries are part MGE Energy's nonregulated energy operations, which were formed to own and lease 
new electric generation projects to assist MGE. 

Based on applicable authoritative guidance, variable interest entities (VIEs) 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. MGE Energy and MGE consolidate variable interest 
entities for which it is the primary beneficiary. 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 West Campus and MGE Power 
Elm Road. Both entities are VIEs. MGE is considered the primary beneficiary of these entities as a result of 
contractual agreements. See Footnotes 2 and 21 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, the disclosure of contingent assets and liabilities 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. 

63 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 derivatives positions. As of 
December 31, 2010 and 2009, the balance is shown net of $0.4 million and $0.6 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, 2010 and 2009, were $0.4 million and $0.6 million, respectively. 

REC allowances are included in inventory and are recorded based on specific identification. MGE's REC 
allowance balances as of December 31, 2010 and 2009, were $2.4 million and $1.3 million, respectively. 

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

Regulatory assets and regulatory liabilities are recorded consistent with regulatory treatment. Regulatory 
assets represent costs which are deferred due to the probable future recovery from customers through 
regulated rates. Regulatory liabilities represent the excess recovery of costs or accrued credits which were 
deferred because MGE believes it is probable such amounts will be returned to customers through future 
regulated rates. Regulatory assets and liabilities are amortized in the Consolidated Statement 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 in future rates.   

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. 
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 

64 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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.  

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

Electric 
Gas  
Nonregulated  

2010   
3.3 % 
1.7 % 
2.3 % 

2009   
3.6% 
3.3% 
2.5% 

2008   
3.7% 
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, 2010 and 2009, MGE had over 
collected $4.8 million and $7.6 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. At the end of the 
month, MGE accrues an estimate for the unbilled amount of energy delivered to customers. See 
Footnote 1.w for further discussion of unbilled revenues.  

MGE's rates include a provision for fuel costs. MGE records an adjustment to revenues for a fuel credit at 
the time MGE's actual fuel costs fall below the bandwidth prescribed by the PSCW and MGE concludes that 
it is probable that the credit will be approved by the PSCW staff. MGE will also record an adjustment to 
revenue when the PSCW institutes a "subject to refund" provision in an order. See Footnote 17 for further 
discussion of the fuel rules. 

n.  Capitalized Interest - MGE Energy and MGE. 

MGE Energy, through its subsidiary MGE Power Elm Road, calculates capitalized interest on construction 
projects for periods where financing is provided by MGE Energy through interim debt. 

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 2010 at 8.36%. Also, MGE received specific 
approval to recover 100% AFUDC on certain environmental costs for Columbia. Although the allowance 
does not represent current cash income, it is recovered under the ratemaking process over the service lives of 
the related properties.  

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. 

65 

 
 
 
  
  
 
 
 
  
  
 
 
 
  
  
 
 
 
  
  
 
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
q.  Capitalized Software Costs - MGE Energy and MGE. 

Property, plant and equipment includes the capitalized costs of internal use software totaling $12.5 million at 
December 31, 2010, and $9.5 million at December 31, 2009. During 2010 and 2009, MGE recorded 
$1.6 million and $1.4 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. MGE 
believes there is no impairment of long-lived assets at December 31, 2010. 

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. 

Regulation 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 
$12.6 million, $13.7 million, and $12.7 million for the years ended December 31, 2010, 2009, and 2008, 
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 will be issued in connection with the plan.  

66 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
MGE Energy and MGE will 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 will be 
subsequently re-measured at each reporting date through the settlement date. Changes in fair value during 
the requisite period will be 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. 

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.  Unbilled Revenues - MGE Energy and MGE. 

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, and customers' bills are based 
on readings of those meters. However, due to the large number of those meters, it is impractical to read all of 
the meters at month-end. Meters are therefore read on a systematic basis throughout the month based on 
established meter-reading schedules. At the end of any month, there exists a quantity of electric and gas 
service that has been delivered but not metered or billed. Management must estimate this usage and related 
revenue. This estimate represents electricity and gas delivered to customers between their meter-read date 
and the end of the period. 

In order to estimate unbilled revenues as of the end of a particular period, MGE performs a series of 
calculations based upon actual and estimated numbers and assumptions. MGE begins by calculating the 
amount of electricity and gas available for sale within its system during that period based upon known inputs 
(i.e., electricity purchases from third parties, gas pipeline reads, and MGE-generated electricity). These 
amounts are then adjusted to deduct the amounts actually included in customers' bills for that period. 

In the case of electricity, the amount is further reduced by estimating the quantity of electricity lost in the 
process of transmitting and distributing it to customers. The resulting unbilled quantities are then allocated to 
various customer classes based upon historical utilization patterns for those customers. MGE applies 
published tariffs to determine the associated revenues. Utilization patterns are based upon assumptions 
regarding weather, economic conditions, and consistency of use over the period in question. Actual use can 
be affected by variations in those items. The resulting estimate is then compared to other available statistics, 
including billed sales for the particular period, in order to confirm its reasonableness. 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 gas, the gross amount available for sale is adjusted by the estimated gas loss factor, which 
reflects an estimate of distribution system losses and heat content differentials between pipeline and 
distribution delivered volumes. The resulting available for sale to consumers amount, which is derived from 
daily pipeline reads, is then compared against the sales billed for the month, with the remainder equaling the 
estimated amount unbilled for the month. The estimated unbilled consumption for the month is then 
allocated across the applicable customer categories where an average per unit rate is applied to calculate the 
unbilled gas revenue. The estimated unbilled consumption is compared to various statistics, including 
unbilled as a percent of available for sale, change in unbilled month to month and change in unbilled 
compared to the prior year in order to confirm its reasonableness. Additionally on an annual basis the 
estimated gas loss factor is reviewed to determine if it is reasonable or whether a change in estimate should 
be made.  

x.  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 

67 

 
 
 
 
 
 
 
 
 
 
 
 
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 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 the VIE:

Long-term debt consists of $50.0 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. 

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.  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. At December 31, MGE has included the following significant accounts on its

MGE Energy's and MGE's available for sale securities represent publicly traded securities and private equity 
investments in common stock of companies in various industries. 

During the year ended December 31, 2010, certain investments were liquidated. As a result of these 
liquidations, MGE Energy and MGE received $0.2 million and $0.1 million, respectively, in cash proceeds. 
In addition, MGE Energy and MGE recorded a less than $0.1 million gain on the sale of investments in the 
income statement for the year ended December 31, 2010. 

During the year ended December 31, 2009, certain investments were liquidated. As a result of these 
liquidations, MGE Energy received $0.1 million in cash proceeds. In addition, MGE Energy recorded a $0.1 
million gain on the sale of investments in the income statement for the year ended December 31, 2009. 

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, 2010, 2009, and 2008, MGE Transco recorded equity earnings from the investment in 
ATC of $8.5 million, $8.2 million, and $7.2 million, respectively. Dividend income received from ATC was 
$6.7 million, $6.3 million, and $5.3 million for the years ended December 31, 2010, 2009, and 2008, 
respectively. During the years ended December 31, 2010, 2009 and 2008, MGE Transco made $0.7 million, 
$3.6 million and $3.4 million, respectively, in cash 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, 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, 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, 2010, 2009, and 2008 is as follows:

Joint Plant Ownership - MGE Energy and MGE. 

a.  Columbia. 

MGE and two other utilities jointly own Columbia, a coal-fired generating facility located in Portage, 
Wisconsin, which accounts for 28% (225 MW) of MGE's net summer rated capacity. Power from this 
facility is shared in proportion to each company's ownership interest. MGE has a 22% ownership interest in 
Columbia. The other owners are WPL (a subsidiary of Alliant), which operates Columbia, and WPSC. 
MGE's share of fuel, operating, and maintenance expenses for Columbia were $35.9 million, $30.1 million, 
and $32.6 million for the years ended December 31, 2010, 2009, and 2008, respectively. See Footnote 18 for 
discussion of MGE's future capital commitments as a result of this ownership interest. 

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

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

Each owner provides its own financing and reflects its respective portion of the facility and operating costs 
in its financial statements. MGE Power West Campus' interest in WCCF and the related accumulated 
depreciation reserves at December 31 were as follows:

Operating charges are allocated to the UW based on formulas contained in the operating agreement. Under 
the provisions of this arrangement, the UW is required to reimburse MGE for their allocated portion of fuel 
and operating expenses. For the years ended December 31, 2010, 2009, and 2008, the UW allocated share of 
fuel and operating costs were $4.0 million, $2.6 million, and $4.8 million, respectively. 

c.  Elm Road. 

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

The remainder of the ownership interest in the Elm Road Units is held by two other entities, one of which is 
also responsible for the Units' operation. Each owner provides its own financing and reflects its respective 
portion of the facility and costs in its financial statements. MGE Power Elm Road's interest in the portion of 
the Elm Road Units in-service and the related accumulated depreciation reserves at December 31 were as 
follows:

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. MGE is earning a return on all regulatory assets net of any 
related liabilities, except for amounts expended for environmental costs. 

Environmental Costs 
MGE has received regulatory treatment on environmental costs including clean up of two landfill sites and a 
substation site and certain environmental costs at Columbia. As it relates to the landfills and substation, the 
regulators have only allowed MGE to recover actual environmental expenditures incurred excluding any carrying 
cost. As of December 31, 2010, MGE has recorded $0.1 million in regulatory assets for these environmental 
costs.  

In addition, MGE has been allowed to defer actual costs plus carrying costs on certain Columbia environmental 
expenditures. As of December 31, 2010, MGE has recorded $1.0 million in regulatory assets related to these 
costs. The pre-construction portion of the costs will be transferred to construction work in progress once a 
Certificate of Authority is received from the PSCW. MGE expects recovery of these costs over the life of the 
installed equipment.

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. 

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. Accordingly, MGE has recorded such adjustments as a regulatory asset. 

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 and are classified as regulatory assets within the consolidated financial statements. 

Other debt related expenses include deferred charges related to the 2027A Series debt. That incremental 
difference between interest earned and interest expensed during construction is currently being amortized over 
the remaining life of the bonds as part of the rate recovery allowed by the PSCW.  

Blount Restructuring Costs 
In 2006, MGE announced a plan to reduce the capacity at Blount from 190 MW to 100 MW by the end of 2011. 
MGE will need to keep Blount available at full capacity until MISO declares that the 90 MW are no longer 
needed for system reliability which is currently anticipated in June 2013. MGE has determined that certain 
employee positions will be eliminated as a result of this plan. Accordingly, this plan has resulted in certain 
involuntary and voluntary severance benefits and retention bonus payments. Recovery of these amounts began in 
2008 and will continue through 2013. Costs will be recovered in rates in the year cash payments are expected to 
be made.  

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. 

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.  

Prior to the change in legislation discussed above, the regulatory liability at December 31, 2009 related to the 
difference in treatment of the Medicare Part D Subsidy for tax and book purposes. For income tax purposes, the 
benefit of this subsidy was excluded from the computation of the unfunded liability. However, for financial 
statement purposes, the unfunded liability included (or was reduced by) the benefit of the Medicare Part D 
Subsidy. Such tax benefits were expected to be returned to customers in rates in future periods.

Elm Road 
In 2010, MGE started collecting lease payments based on the expected commercial operation dates of the Elm 
Road Units. Any 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 
transition 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.  

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.  

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. 

Customer Fuel Credit 
See Footnote 17 for further discussion. 

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. 

7. 

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 are covered by a shelf registration statement that MGE Energy filed with the SEC. For the 
year ended December 31, 2010, MGE Energy did not issue any new shares of common stock under the Stock 
Plan. However, for the year ended December 31, 2009, MGE Energy issued 209,065 new shares of common 
stock under the Stock Plan for net proceeds of $6.3 million.  

Since 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 year ended December 31, 2010 and 2009, MGE Energy paid $34.4 million (or $1.49 per share) 
and $33.7 million (or $1.46 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 year 
ended December 31, 2010 and 2009, MGE paid $26.2 million and $19.3 million, respectively, in cash 
dividends to MGE Energy.

Noncontrolling Interest - MGE. 

a.  MGE Power West Campus. 

MGE Power West Campus is not a subsidiary of MGE; however, it has been consolidated in the 
consolidated financial statements of MGE (see Footnote 2). MGE Power West Campus is 100% owned by 
MGE Power and MGE Power is 100% owned by MGE Energy. MGE Energy's proportionate share of the 
equity and net income (through its wholly owned subsidiary MGE Power) of MGE Power West Campus is 
classified within the MGE financial statements as noncontrolling interest. Noncontrolling interest on the 
balance sheet related to MGE Power West Campus at December 31, 2010 and 2009, is $32.7 million and 
$29.0 million, respectively. For the years ended December 31, 2010, 2009, and 2008, MGE Power had 
earned $7.7 million, $7.6 million, and $7.6 million, net of tax, from its interest in MGE Power West 
Campus, respectively. This amount is recorded as noncontrolling interest, net of tax, on MGE's consolidated 
statement of income. 

b.  MGE Transco. 

At December 31, 2010, MGE is the majority owner, and MGE Energy is the minority owner, of MGE 
Transco. MGE Energy's proportionate share of the equity and net income of MGE Transco is classified 
within the MGE financial statements as noncontrolling interest. Noncontrolling interest on the balance sheet 
related to MGE Transco at December 31, 2010 and 2009, is $9.9 million and $9.8 million, respectively. For 
the years ended December 31, 2010, 2009, and 2008, MGE Energy had earned $1.8 million, $1.5 million, 
and $0.8 million, net of tax, from its interest in MGE Transco, respectively. These amounts are recorded as 
noncontrolling interest, net of tax, on MGE's consolidated statement of income.

(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)  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. 

(c)  On December 21, 2010, MGE redeemed the outstanding $15 million principal amount of its 6.58% 
Medium-Term Notes due April 1, 2012. It paid a redemption price equal to the principal amount of 
those notes, plus accrued interest to the redemption date, plus a make-whole premium equal to 
$1.1 million, which will be amortized over the life of the Notes. 

(d)  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. 

(e)  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

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

a.  MGE Energy. 

At December 31, 2010, MGE Energy had an unsecured, committed revolving line of credit of $40 million 
expiring July 30, 2013. At December 31, 2010, $19 million in 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 
agreements. 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. 

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, 2010, 
MGE had an unsecured, committed revolving line of credit for $75 million expiring July 30, 2013. 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, 2010, no borrowings were outstanding under this facility; however, there was $3.5 million 
in commercial paper outstanding.  

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 agreements. 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.

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.

        (b)     These amounts are shown gross and exclude $0.4 million of collateral that was posted 
                  against derivative positions with counterparties. 

No transfers were made in or out of Level 1 or Level 2 for the year ended December 31, 2010. 

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 week maturity increased by 1% compounded monthly, with a minimum annual 
rate of 7%, compounded monthly, and are therefore based upon observable market data and classified as 
Level 1.

(c) 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 
shareholders have the ability to receive a set percentage of the benefit or loss from these deals if 
certain thresholds are 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.

The valuation allowance reduces MGE Energy'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, 2010, MGE Energy had approximately $7.5 million of state tax net 
operating loss deductions that expire between 2011 to 2019 if unused. 

b.  MGE Income Taxes. 

MGE Energy files a consolidated federal income tax return. The subsidiaries calculate their respective 
federal income tax provisions as if they were separate taxable entities.  

On a separate company basis, the components of MGE's income tax provision are as follows for the years 
ended December 31:

The valuation allowance reduces 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, 2010, MGE had approximately $7.5 million of state tax net operating 
loss deductions that expire between 2011 to 2019 if unused. 

c.  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.

Unrecognized tax benefits are liabilities shown with Other Deferred Liabilities on the December 31, 2010 
and December 31, 2009, 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 repairs. This method change accelerated tax deductions for electric repairs in accordance with 
Treasury Regulations and case law, as compared to the prior method of claiming tax depreciation on project 
costs. At December 31, 2010, MGE Energy and MGE have an unrecognized tax benefit 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 repairs. Unrecognized tax benefits at December 31, 2009, related to federal 
permanent differences and tax credits, the realization of which would not significantly impact the effective 
tax rate.  

The unrecognized tax benefits at December 31, 2010, are not expected to significantly increase or decrease 
within the next twelve months. 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. The following 
table shows tax years that remain subject to examination by major jurisdiction:

d.  Medicare Part D Subsidy. 

On March 23, 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, 2010, 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 
$1.6 million, $1.3 million, and $1.2 million in 2010, 2009 and 2008, 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 8.5% for both 2010 and 2009. In 2011, 
MGE will lower the return on asset assumption from 8.5% to 8.25%. 

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 2010 and 2009, and the target allocation for 2011, 
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, 2010. 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, 2010, 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, 2010: 

Cash and Cash Equivalents – This includes highly liquid investments with maturities of less than 3 months 
which are traded in active markets. 

Equity Securities – These 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. 

The Fair Value of MGE's plan assets, by asset category are as follows:

The fair value of plan assets for these postretirement benefit plans is $20.9 million and $17.3 million at the 
end of 2010 and 2009, respectively. The expected long-term rate of return on these plan assets was 7.39% in 
2010 and 2009. 

Of the above amounts, $17.9 million and $13.4 million at the end of 2010 and 2009, respectively, were held 
in the master pension trust and are allocable to postretirement health expenses. The target asset allocation 
and investment strategy for the portion of assets held in the master pension trust are the same as that 
explained for MGE's pension plans. 

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

i.  Expected Cash Flows. 

Contributions to the plans for 2011 are expected to be approximately $21 million and for 2012 through 2015 
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 2010, MGE made $16.9 million in employer contributions to its pension and postretirement plans related 
to the 2009 and 2010 plan years.

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. 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 measured 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 has 
been subsequently re-measured at December 31, 2010, as required by applicable accounting standards. Changes 
in fair value as well as the original grant have been recognized as compensation cost. Since this amount will be 
re-measured throughout the vesting period, the compensation cost is subject to variability. These units are subject 
to either a four or 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 also using the graded 
vesting method. 

During the years ended December 31, 2010, 2009, and 2008, MGE recorded $1.2 million, $0.8 million and 
$0.5 million, respectively, in compensation expense as a result of the Performance Unit Plan. No forfeitures 
occurred during the years ended December 31, 2010 or 2009. A forfeiture of less than $0.1 million occurred 
during the year ended December 31, 2008. At December 31, 2010, $1.8 million of these awards were 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, including within the state of Wisconsin. 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. In 
January 2009, MISO implemented and MGE began participating in the ancillary services market (ASM). 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 will provide the reserves for MGE's load, and MGE may offer 
to sell reserves from its generating units.  

In June 2009, MISO implemented and MGE began participating in the voluntary capacity auction. The voluntary 
capacity auction 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 to potentially obtain the 
necessary aggregate planning resource credits to meet their planning reserve margin requirement. Generator 
owners may participate to sell any excess aggregate planning resource credits that are not needed.  

PJM  
MGE is a member of PJM. PJM, an RTO, is a neutral and independent party that coordinates and directs the 
operation of the region's transmission grid, 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, that is affected by 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 $94.9 million, 
$74.4 million, and $163.8 million reduction to sales to the market and purchased power expense for the years 
ended December 31, 2010, 2009, and 2008, respectively.

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

a.  Purpose. 

As part of its regular operations, MGE enters into contracts, including options, swaps, futures, forwards, and 
other contractual commitments, to manage its exposure to commodity prices and gas revenues. To the extent 
that these contracts are derivatives, MGE assesses whether or not the normal purchases or normal sales 
exclusion applies. For contracts to which this exclusion cannot be applied, MGE Energy and MGE recognize 
such derivatives in the consolidated balance sheets at fair value. The majority of MGE's derivative activities 
are conducted in accordance with its electric and gas risk management program, which is approved by the 
PSCW and limits the volume MGE can hedge with specific risk management strategies. The maximum 
length of time over which cash flows related to energy commodities can be hedged is two 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: 

Commodity derivative contracts .....................

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

  December 31, 2009 

647,560 MWh 
6,530,000 Dth 
3,003 MW 

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, 2010 
and 2009, MGE Energy and MGE had $0.5 million and $0.4 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, 2010 the cost 
basis of exchange traded derivatives and FTRs exceeded their fair value by $0.2 million. At December 31, 
2009, the fair value of exchange traded derivatives and FTRs exceeded their cost basis by $0.3 million, 
respectively. 

MGE has also entered into a ten-year purchased power agreement which 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, 2010 and 2009, reflects a loss position of $19.0 
million and $12.8 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, 2010, no counterparties are 
in a net liability position. As of December 31, 2009, certain counterparties are in a net liability of less than 
$0.1 million.

MGE entered into a non-exchange traded HDD collar covering the period from January 2008 to March 2008. 
Actual heating degree days during the aforementioned period exceeded the ceiling; therefore, MGE recorded 
a $1.5 million expense (including a $0.2 million premium) on the collar in the first quarter of 2008.  

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, 2010, no counterparties have defaulted. 

17.  Rate Matters - MGE Energy and MGE. 

a.  Rate proceedings. 

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%. See below for further description of fuel 
rules. 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.  

On December 14, 2007, the PSCW authorized MGE to increase 2008 electric rates by 4.8% or $16.2 million 
and to increase gas distribution rates by 2.8% or $7.8 million. The electric increase covered costs for MGE's 
new wind energy projects, statewide energy efficiency and renewable energy programs, transmission 
improvements by ATC, and accelerated costs to discontinue coal use at the Blount Station. In addition to 
funding the statewide energy programs, the natural gas rate increase covered costs for area gas construction 
projects needed to accommodate customer growth. Authorized return on common stock equity was set at 
10.8% based on 57.4% utility common equity.  

b.  Fuel rules. 

Actual electric fuel costs are subject to reconciliation to the amount approved by the PSCW in MGE's rate 
order covering the applicable period. Known as "fuel rules," the process can produce a fuel surcharge for 
MGE or require MGE to make a refund in the form of a credit, to the extent that the actual fuel costs are 
outside a range higher or lower than the level authorized by the PSCW in that rate order.  

Under fuel rules, MGE could apply for a fuel surcharge if its actual electric fuel costs exceeded 102% of the 
electric fuel costs allowed in its latest rate order. Conversely, MGE could be required to provide a fuel credit 
to its customers if actual electric fuel costs were less than 98% of the electric fuel costs allowed in that order. 

As of December 31, 2010, MGE's fuel costs are within the range authorized by the PSCW in the most recent 
rate order; therefore, no fuel credits or surcharges were necessary. 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 April 
2010, the PSCW authorized a refund of $0.3 million of over collected 2009 fuel costs and accrued interest 
via a one-time credit, which was applied to customers' April 2010 bills. 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. 

94 

 
 
 
 
 
 
 
 
 
 
 
 
 
In May 2010, Wisconsin's governor signed 2009 Assembly Bill 600 into law as Act 403. The new law 
requires 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 its electric retail customers. The PSCW approved the new fuel 
rules on December 27, 2010, and will be effective January 1, 2011.  

18.  Commitments and Contingencies. 

a.  Coal Contracts - MGE Energy and MGE. 

Fuel procurement for MGE's jointly owned Columbia and Elm Road Units are handled by Alliant and 
Wisconsin Energy Corporation, respectively, the operating companies. 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. The following table identifies MGE's share, as of December 31, 2010, of the 
total coal commitments for the Columbia and Elm Road Units for the next five years.

b.  Purchased Power Contracts - MGE Energy and MGE. 

MGE has several purchase power agreements to help meet future electric supply requirements. Management 
expects to recover these costs in future customer rates. The following table identifies MGE's total 
commitments for energy and purchase power agreements for capacity and wind purchase power agreements, 
as of December 31, 2010, for the next five years.

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.  

c.  Natural Gas Transportation and Storage Contracts - MGE Energy and MGE. 

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. As of 
December 31, 2010, the fixed payments for firm supply pipeline transportation and storage capacity for the 
next five years are as follows:

d.  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. As of 
December 31, 2009, the EPA has 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. We will not know if additional costs exist at the site until cleanup is completed. At 
December 31, 2010, 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 
the 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. 

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 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. Columbia will need to demonstrate compliance when it files its permit renewal 
application in September 2011. 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 Unit's. If any of MGE's plants are unable to 
demonstrate compliance with this rule then we may incur capital costs associated with modifying our plants 
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 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 MGE's limits will be at any of our facilities that will be 
subject to this rule (Blount, Columbia, Elm Road and WCCF). MGE may incur additional capital or 
operational expenditures and/or need to install additional pollution controls to meet the new phosphorus 
limits.

WPDES Mercury Discharge Limit 
WPDES permit holders for coal-fired electric power plants are required to meet mercury effluent limits. If 
permit holders do not meet the mercury limits they must apply for a variance as part of their next WPDES 
permit renewal with the WDNR. MGE applied for a mercury variance for Blount when it submitted its 
permit renewal in the fall of 2010. Although we cannot predict the outcome of the variance request, if the 
variance is not approved, Blount may need to incur additional capital or operational expenditures and/or 
install additional pollution controls to meet the mercury limits.  

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.  

Wisconsin State Mercury Rule 
As of January 2010, "major utilities" (such as the operators of the Columbia and Elm Road Units) must 
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 and has submitted a 
Certificate of Authority (CA) to the PSCW, to install pollution controls needed to meet this and other rules 
(see the Columbia subsection in Footnotes for additional information on this CA).  

BART/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 affect 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 and requires companies to evaluate the best technology to reduce visibility impairment. 

Under the CAIR, the EPA and WDNR concluded that compliance with CAIR emissions limitations would 
serve as compliance with BART requirements for SO2 and NOx emissions (CAIR=BART). Thus, owners 
subject to BART would have the option of purchasing allowances under the CAIR rather than installing 
pollution controls. However, with the CAIR remanded and the introduction of the EPA's Transport Rule, the 
future of BART regulation is uncertain. Currently CAIR=BART continues, however we may incur 
additional capital expenditures at Columbia if the Transport Rule ends the CAIR=BART determination and 
does not introduce a new determination that the Transport Rule=BART. 

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 (NO2), particulate matter (PM), ozone, SO2, 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 

97 

 
 
 
 
 
 
 
 
 
 
every five years. Monitoring data is 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 trouble 
meeting new standards not previously modeled. Modeling performed by the WDNR for MGE's permitted 
facilities has demonstrated compliance with NAAQS. Additional modeling may be required in future 
permitting actions. 

Particulate Matter NAAQS 
In 2006, the EPA lowered the 24-hour NAAQS for fine particulate matter. In October 2009, the EPA 
designated the counties where the Elm Road Units are located as not complying with the lower standard. 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 February 2009, the D.C. Circuit Court 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 will need to evaluate particulate matter NAAQS in 2011 as part 
of its five-year review. If the standards become more stringent, more counties where our generation is 
located could become nonattainment; however, that cannot be known until the standards are finalized. 

Ozone NAAQS  
In January 2010, the EPA proposed a rule change lowering the acceptable level of ozone in ambient air, with 
a final rule scheduled for July 2011. A lowered standard could put areas in which MGE has generating 
facilities into noncompliance and could increase capital or operating costs at MGE facilities due to the need 
to comply with revised emissions limits.  

Nitrogen Dioxide NAAQS 
In January 2010, the EPA adopted a nitrogen dioxide (NO2) NAAQS focusing on near-roadway exposures to 
NO2. Final decisions on whether areas comply with the NO2 NAAQS will be made by January 2012. It is 
unclear at this time whether MGE's power plants would be affected by the revision, since it is not yet known 
what areas may be in noncompliance and what steps may be required to achieve compliance. 

Sulfur Dioxide NAAQS 
In June 2010, the EPA finalized its sulfur dioxide NAAQS. States are required to make 
attainment/nonattainment recommendations in 2011, with the EPA making final designations in 2012. It is 
unclear at this time whether MGE's power plants would be affected by the revision, since it is not yet known 
what areas may be in noncompliance and what steps may be required to achieve compliance. 

Columbia 

Title V Operating Permit Petition 
In September 2008, the WDNR issued a Title V renewal operating permit to WPL for Columbia. 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. A citizen group petitioned the 
EPA to object to the issuance of the permit renewal. In October 2009, the EPA sent the operating permit 
back to the WDNR for further review. The EPA order gave the WDNR 90 days to address the objections. On 
September 22, 2010, the WDNR acted on the order by issuing a draft construction permit for public 
comment. By letter dated November 24, 2010, the EPA objected to the draft construction permit asserting 
that the WDNR had not adequately responded to the EPA Order. In response to the EPA's objection, the 
WDNR issued a letter on February 8, 2011 stating its determination to not issue either the proposed 
construction permit or the revised operation permit for Columbia. Thus the permits currently in effect for 
Columbia remain in place at this time. 

Columbia Clean Air Act Litigation 
In December 2009, the EPA sent a Notice of Violation (NOV) to MGE as one of the co-owners of 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 PSD program requirements, Title V 
Operating Permit requirements of the CAA and the Wisconsin SIP.  

98 

 
 
 
 
 
 
 
 
 
 
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.  

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), caps for emissions and limitations on 
generation (including retirement of generating units) and other supplemental environmental projects. Should 
similar remedies be required for final resolution of these matters at Columbia, MGE would likely incur 
additional capital and operating expenditures. MGE and the other co-owners of Columbia are exploring 
settlement options with the EPA and Sierra Club while simultaneously defending against these allegations. 
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. At this time, MGE 
is unable to predict 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. MGE has not 
recognized any loss contingency amounts as of December 31, 2010. 

Certificate of Authority 
In April 2009, the Columbia owners filed with the PSCW a request for authorization, in the form of a 
Certificate of Authority, to undertake an emissions reduction project at Columbia and to recover the 
associated capital expenditures in rates. MGE's share of those expenditures is currently estimated at 
approximately $140 million, based upon WPL's estimate of the proposed project capital expenditures. The 
projects are also expected to cause an increase in Columbia's ongoing operating expenses. A decision by the 
PSCW could come as early as February 2011, which could approve, modify or deny the proposed project. 
MGE would be entitled to recover in its rates its share of the costs of the approved project. Conversely, if 
some portion of the project were denied, the Columbia owners would need to consider options, including an 
appeal of the ruling or modification of the proposed project, inasmuch as costs associated with the denied 
portion of the project would not be recoverable in rates unless overturned on appeal. The PSCW has 
permitted MGE to defer pre-certification and pre-construction costs related to compliance with 
environmental regulations at Columbia. Additionally, MGE is entitled to a carrying cost on the related pre-
construction costs at a 100% AFUDC rate. As of December 31, 2010, MGE had incurred $0.9 million 
(excluding carrying costs) in deferred pre-certification and pre-construction expenditures at Columbia related 
to the proposed project. 

See Footnote 21 for additional environmental commitments related to the Elm Road Units. 

e.  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 
August 31, 2011. At December 31, 2010, 2009, and 2008, respectively, MGE had sold a $3.6 million, 
$3.7 million, and $3.8 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 each of the years 
ended December 31, 2010, 2009, and 2008, MGE had recorded a servicing asset of $0.1 million. MGE 
recognized gains of less than $0.1 million for each of the years ended December 31, 2010, 2009, and 2008, 
in connection with the sale of loan assets. The servicing asset amount amortized in 2010 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 2010, 2009, and 2008, MGE received approximately 

99 

 
 
 
 
 
 
 
 
 
$0.5 million, $0.6 million, and $0.8 million, respectively, from the financial institution for the sale of loan 
assets. During those same years, payments of $0.7 million, $0.8 million, and $0.9 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, 2010, 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 customer loan. Principal payments for the next five years on the loans are:

f.  Elm Road Purchase Commitments - MGE Energy and MGE. 

Based on current forecasts, the remaining capital costs for the Elm Road Units are estimated to be 
$2.2 million in 2011. See Footnote 21a for additional information regarding construction costs associated 
with the Elm Road Units. 

g.  Top of Iowa III Wind Project Commitments - MGE Energy and MGE. 

MGE has a service and maintenance agreement related to the Top of Iowa III wind project which results in a 
commitment of $0.9 million in each year for 2011 and 2012. 

h.  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.

i.  Other Legal Matters. 

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.

j.  Wind Development Rights - MGE Energy. 

In June 2009, MGE Energy, through its subsidiary MAGAEL, LLC, entered into agreements 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. Total 
payments of $1.5 million have been made. Future payments at December 31, 2010, related to these 
agreements are estimated to be:

These wind development rights may potentially be used to develop wind farms in three counties in Iowa up 
to approximately 175 MWs; however, neither MAGAEL nor MGE Energy has any obligation to build any 
wind generators at these sites.  

k.  Smart Grid Investment Grant – MGE Energy and MGE. 

MGE has been approved 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 proposed projects to more than $11 million. The proposed projects will install 
technologies to boost efficiency, enhance service and improve reliability for customers. The stimulus grant 
will help fund the following projects: advanced metering infrastructure, plug-in hybrid electric vehicles 
support, and distribution management. Committed payments for these projects are $0.3 million in 2011. 

l.  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 $0.4 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, 2010, 
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 $0.1 million in 2010, and expects $0.3 million in 2011 and $0.4 million in 2012. 

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 reduce capacity at Blount from 190 MW to 100 MW by the end of 2011. As 
part of the plan, coal use at Blount will be discontinued. MGE has determined that certain employee positions 
will be eliminated as a result of this plan.  

In March 2009, MGE received notification from MISO that in order to meet national electric system reliability 
standards, MGE will need to keep Blount available at its full capacity until MISO declares that the 90 MW are no 
longer needed for system reliability. Currently, MGE estimates the reduction in capacity will occur in 2013. The 
transition from burning coal to burning only natural gas will still occur by the end of 2011. After the transition, 
the entire plant will be operated exclusively on natural gas. MGE is working with MISO to develop a detailed 
agreement for this continued operation, which among other things will include a mechanism for cost recovery.

In January 2010, MGE announced it will change its primary fuel at Blount from coal to natural gas. Coal will 
become the secondary fuel at Blount. This switch to natural gas as a primary fuel occurred in March 2010. As a 
result of this change, certain employee positions were eliminated and severance benefits in 2010 totaled 
$0.5 million. These severance benefits were accelerated into 2010 from 2011, but were offset by lower payroll 
charges in 2010. 

MGE has entered into agreements providing severance benefits to employees affected by the exit plan. These 
benefits are being recognized ratably over the expected future service period of the employees. Total benefits 
expected to be paid are as follows: $0.3 million in 2012 and $0.3 million in 2013. Total benefits paid as of 
December 31, 2010, were $1.1 million. 

MGE continues to recover in rates the costs associated with the severance benefits at Blount in the year of 
expected cash payment. The severance charges to be recovered in rates have been deferred and recognized on the 
consolidated balance sheet of MGE Energy and MGE as a regulatory asset. 

The following table presents the activity in the restructuring accrual from December 31, 2009, through 
December 31, 2010:

The exit plan has also resulted in accelerated depreciation for the Blount assets expected to be retired in 2011 and 
2013. 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 year ended December 31, 2010 and December 31, 
2009, $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 an electric substation, a combustion turbine generating unit, wind generating 
facilities, and photovoltaic generating facilities, all of which are located on property not owned by MGE 
Energy and MGE and would 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 polychlorinated biphenyls, and the 
proper disposal and removal of tanks. Changes in management's assumptions regarding settlement dates, 
settlement methods, or assigned probabilities could have had a material effect on the liabilities recorded by 
MGE at December 31, 2010, 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. 

In February 2010, MGE Power Elm Road recorded an obligation for the fair value of its legal liability for 
AROs associated with the demolition and removal of the Elm Road Units. Provisions for these demolition 
and removal costs are included in the facility lease agreements. At December 31, 2010, this liability is 
estimated at $0.1 million and is included in other deferred liabilities.

In 2010 and 2009, MGE reduced accumulated accretion by $0.1 million due to the removal and retirement of 
assets. 

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, 2010 and 2009, there were $12.3 million and $12.2 million of these 
costs recorded as regulatory liabilities within the financial statements, respectively.  

21.  Elm Road - MGE Energy and MGE. 

a.  Construction. 

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

The estimated share of capital costs for that ownership interest in both units is approximately $180 million 
which includes the Bechtel settlement described below (excluding capitalized interest). As of December 31, 
2010, $122.6 million related to this project was placed in-service and $55.1 million (excluding capitalized 
interest) related to this project is reflected in the construction work in progress balance on MGE Energy's 
and MGE's consolidated balance sheets. MGE Power Elm Road calculates capitalized interest on the Elm 
Road units until their respective in-service dates. As of December 31, 2010, MGE Power Elm Road recorded 
a total of $16.9 million in capitalized interest related to the Elm Road Units.  

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 $191 million or 8.7% 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 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. 

b.  Nonregulated Revenues. 

MGE has approval from the PSCW to defer the recovery of the payments made to MGE Power Elm Road 
for carrying costs during construction of the generating units, management fees, and community impact 
mitigation costs. MGE estimates that the total carrying costs on the Elm Road Units will be $62.6 million. 
This estimate is subject to change based on changes in interest rates, timing of capital expenditures, and the 
total project cost.  

MGE began collecting the carrying costs in rates in 2006. These amounts are being collected over multiple 
years. Of these costs, MGE estimates that $17.1 million relates to the capitalized interest and the debt portion 
of the facility. These costs will be recognized over the period in which the generating units will be 
depreciated. The remaining $45.5 million represents the equity portion and is being recognized over the 
period allowed for recovery in rates.  

During 2010, MGE recovered $16.5 million in electric rates for costs associated with the Elm Road Units. 
For the year ended December 31, 2010, $5.1 million related to the carrying costs were recovered in rates. Of 
this amount, $1.4 million relates to the debt portion of the facility and was deferred on the consolidated 
financial statements of MGE Energy and MGE. Since February 2, 2010, when the Elm Road Unit 1 was 
placed in-service, $0.2 million of the debt portion was recognized. The remaining $3.7 million represents the 
equity portion and was recognized as nonregulated revenues in the consolidated financial statements of MGE 
Energy and MGE. Furthermore, an additional $0.9 million was recognized as a true-up of equity during the 
year ended December 31, 2010. 

c.  WPDES Permit. 

Under an agreement reached in July of 2008, the joint owners of the Elm Road Units are committed to 
various environmental projects, including projects designed to address greenhouse gas emissions and water 
quality. MGE's share of those commitments involved a payment of $0.4 million for greenhouse gas 
reduction efforts. Additional payments of approximately $0.3 million, subject to regulatory approval, will be 
made annually over 24 years (2011-2034) to address water quality issues in Lake Michigan. In 
December 2009, the PSCW authorized recovery of the 2011 payment to address water quality issues.  

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

MGE. 

a.  Consolidation of Variable Interest Entities. 

In June 2009, the FASB issued authoritative guidance within the Codification's Consolidation topic 
regarding variable-interest entities. This guidance amends the criteria used to determine which entity, if any, 
has a controlling financial interest in a VIE. It replaces the quantitative calculation of risks and rewards with 
a qualitative approach focused on identifying which entity (1) has the power to direct the activities of a VIE 
that most significantly impact the VIE's economic performance and (2) has the obligation to absorb losses of 
the VIE or the right to receive benefits from the VIE. This guidance also requires ongoing assessments of 
whether an entity is the primary beneficiary of a VIE. This authoritative guidance became effective January 
1, 2010. The Company evaluated its VIE's and determined this authoritative guidance did not have a material 
impact. MGE Power West Campus and MGE Power Elm Road continue to be a VIE's under applicable 
accounting requirements; therefore, MGE continues to consolidate both entities into its financial results and 
financial position. 

104 

 
 
 
 
 
 
 
 
 
 
 
b.  Transfers and Servicing of Financial Assets. 

In June 2009, the FASB issued authoritative guidance within the Codification's Transfers and Servicing topic 
regarding accounting for transfers of financial assets. This statement removes the concept of a qualifying 
special-purpose entity from authoritative guidance on accounting for transfers and servicing of financial 
assets and extinguishments of liabilities. This statement also removes the exception for qualifying special-
purpose entities from authoritative guidance on consolidation of variable interest entities. The authoritative 
guidance became effective January 1, 2010. The Company evaluated its shared savings program under the 
new guidance and determined it did not have any financial impact or impose any additional disclosure 
requirement. 

c.  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 are 
effective January 1, 2011. The authoritative guidance effective beginning January 1, 2010, did not have any 
financial impact, but required additional disclosures. See Footnote 11 for additional information. The 
authoritative guidance effective beginning January 1, 2011 will not have a material financial impact, but will 
require additional disclosures. 

23. 

Segment Information - MGE Energy and MGE. 

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

The nonregulated energy operations are conducted through MGE Energy's subsidiaries: MGE Power, MGE 
Power West Campus, and MGE Power Elm Road. These subsidiaries have been formed to construct, own and 
lease new electric generating capacity to assist MGE. MGE Power West Campus owns a controlling interest in 
the electric generation plant of a natural gas-fired cogeneration facility on the UW campus, which is leased to 
MGE, and MGE Power Elm Road has an undivided 8.33% ownership interest in each of two 615 MW coal-fired 
generating units in Oak Creek, Wisconsin. MGE Power Elm Road's portion is also being 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 to the consolidated financial statements 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 West 
Campus/MGE Power Elm Road are based on terms previously approved by the PSCW. Consistent with internal 
reporting, management has presented the direct financing capital lease between MGE and MGE Power West 
Campus/MGE Power Elm Road based on actual lease payments included in rates. Lease payments made by MGE 
to MGE Power West Campus and MGE Power Elm Road are shown as operating expenses. The lease payments 
received by MGE Power West Campus and MGE Power Elm Road from MGE are shown as lease income in 
interdepartmental revenues. The depreciation expense associated with the WCCF and Elm Road Units is 
reflected in the nonregulated energy segment.

During 2010, 2009, and 2008, MGE recorded $26.4 million, $22.7 million, and $21.9 million, respectively for 
transmission services received from ATC. MGE also provides a variety of operational, maintenance, and project 
management work for ATC, which is reimbursed by ATC. For the year ended December 31, 2010, MGE had no 
receivable due from ATC. For the years ended December 31, 2009, and 2008, MGE had a receivable due from 
ATC of $0.1 million, and $0.2 million, respectively.  

WEPCO and ATC entered into an interconnection agreement related to transmission system upgrades for the Elm 
Road project, in which MGE Power Elm Road has an undivided 8.33% ownership interest. At December 31, 
2008, MGE Power Elm Road had a receivable from ATC totaling $3.2 million, related to the work done by ATC 
on the Elm Road interconnection project. The full $3.2 million receivable was satisfied during 2009. No 
outstanding balance from ATC was due at December 31, 2009.

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures 

During the fourth quarter of 2010, 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 
executive 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, 2010, 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 continually 
strive to improve its disclosure controls and procedures to enhance the quality of its financial reporting. 

During the quarter ended December 31, 2010, there were no changes in MGE Energy or MGE's internal controls over 
financial reporting that materially affected, or are reasonably likely to materially affect, 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, 2010. As a result of that assessment, management determined that there were no 
material weaknesses as of December 31, 2010 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.

OF DIRECTORS" in MGE Energy's definitive proxy statement (2011 Proxy Statement) to be filed with the SEC on or 
before March 23, 2011. Information relating to compliance with Section 16(a) of the Securities Exchange Act of 1934 is 
incorporated herein by reference to the information under the heading "BENEFICIAL OWNERSHIP - Section 16(a) 
Beneficial Ownership Reporting Compliance" in the 2011 Proxy Statement. 

The information required by Item 10 relating to executive officers is set forth above in Item 1. Business - Executive

Code of Ethics

Item 11. Executive Compensation. 

See Item 12. 

Amendment of Key Employee Severance Agreements 

On February 18, 2011, the MGE Energy Compensation Committee recommended, and the MGE Energy Board of 
Directors approved, an amendment to the existing key employee severance agreements between MGE and each of its 
executive officers, including the named executive officers. The severance agreements provide for specified payments in 
the event that a covered executive's employment with the company is terminated following a change in control. The 
amendment provides for the elimination of provisions in the severance agreements that required MGE: 

  To  continue  a  covered  executive's  health,  life  and  disability  benefits  for  period  of  two  or  three  years 

(depending upon the individual agreement) following the termination of employment. 

  To  continue  company-sponsored  scholarship  benefits  for  a  covered  executive  who  had  children  eligible  to 

receive such benefits. 

  To waive retiree health plan eligibility requirements for a covered executive who is age 50 or over. 

  To pay a gross-up payment to a covered executive for any excise taxes the executive may incur as a result of 

change in control related payments. 

The amendment also limits the payments that may be made under a severance agreement. Under that limit, payments 
under a severance agreement, when combined with any other payments received by the executive as a result of the 
change in control, would generally be limited to not more than 2.99 times the average annual compensation included in 
the executive's gross income for the five calendar years prior to the calendar year in which the change in control occurs. 

The amendment to an individual executive's severance agreement will become effective as of December 30, 2010 upon 
its execution by that executive. It is expected that the named executive officers will execute an amendment to their 
individual severance agreements. For additional information regarding the severance agreements, please see the 
description appearing under "Executive Compensation – Potential Payments on Employment Termination or Change in 
Control – Employment Termination in Connection With a Change in Control" in MGE Energy's proxy statement dated 
March 24, 2010, which was filed with the SEC on March 24, 2010. A copy of the amendment, and the form of the key 
employee severance agreement which reflects that amendment, are filed as exhibits to this annual report on Form 10-K.

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 
subsidiaries. For Parent Company only presentation, investment in subsidiaries are accounted for using the equity 
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 2010 Annual Report on Form 10-K. 

The Company adjusted $50.0 million from long-term debt to short-term debt to correct the presentation of debt at 
December 31, 2009. 

2.

As of December 31, 2010, MGE Energy had access to unsecured credit facilities with aggregate bank

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 $28.8 million plus 
dividends on 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, 
2010, is estimated to be 58.5% as determined under the calculation used in the rate proceeding. MGE paid cash 
dividends of $26.2 million to MGE Energy in 2010. 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 West Campus or MGE Power Elm Road, 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, 2010, approximately $248.6 million was available for the payment of 
dividends under this covenant. 

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