Shareholders

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

Financial strength

2013 was another year of strong 
financial  performance.  In 
December,  we  announced  a 
3-for-2 stock split effective on 
Feb. 7, 2014. As an example, for 
every 100 shares held prior to 
the split, shareholders now own 
150 shares of MGE Energy. The 
stock  split  will  help  keep  the 
stock affordable for investors. As a result of the stock split, the per 
share value of the stock price, earnings, book value and dividend 
were  adjusted  to  reflect  this  increase  in  the  number  of  shares 
outstanding. The stock split underscores the confidence your Board 
of Directors has in our commitment to shareholder value.

At the closing bell on Dec. 31, our stock price hit $38.48, up from 
a closing of $33.97 at the end of 2012. Over the last 10 years, our 
stock price has outperformed the major national indices of the Dow 
Jones Industrials and the S&P 500. Our stock price has nearly doubled 
in the last decade.

The Board of Directors also increased the dividend for the 38th 
consecutive year. The dividends paid per share reached $1.07 in 
2013. MGE Energy is one of only four combination utilities in the 
country to increase its dividend for 38 or more consecutive years. 
The financial publisher Mergent ranks us as a “Dividend Achiever.”

Many shareholders choose to reinvest their dividends to grow their 
value. The total return on your investment combines stock price 
with dividends. In 2013, MGE Energy’s total return grew 17%.

We reported earnings of $2.16 per share in 2013 compared to  
$1.86 per share in 2012. Earnings benefitted primarily from a  
25.7% increase in natural gas sales in part due to colder weather. 
Earnings also benefitted from our ongoing cost-containment efforts. 

Thank  you  for  your 
ownership  of  MGE  Energy.  Some  of  you  are 

new to our company. Others have held our stock 

for  many  years.  All  of  you  contribute  to  our 

success as a community energy company. We 

appreciate your confidence and investment in 

MGE Energy.   

To you our shareholders, to our customers, to 

our community and to our employees, we give 

thanks. With this year’s annual report, we take 

the  opportunity  to  share  our  gratitude  and 

appreciation.

Letter  
to our

Shareholders

Shareholders  We  appreciate 
your loyalty. Kari Foster of our 
Shareholder Services depart-
ment meets with an investor. 

Customers  Thank you for your 
engagement. MGE’s Jim Jenson 
explains electricity to students 
producing energy on a bicycle. 

Communities  We are grateful to 
serve a dynamic area. Madison’s 
economy is one of the strongest 
nationwide. 

Employees  We appreciate your 
commitment to providing 24/7 
customer service. MGE’s Dylan 
Anderson works on a gas project. 

Smaller distributed generation also has a role in our energy future. 
Our technology demonstration program has more than 30 distributed 
generation projects located throughout our community. They range 
from photovoltaic installations to a micro-cogeneration unit. All 
feed  into  the  community  energy  grid  of  resources  that  serve  
our customers.

Rapid improvements in technology open doors to new possibilities. 
We  position  ourselves  to  pursue  technology  that  benefits  
our community.

The expanding market for fueling vehicles is a good example.  
Many of our customers are early adopters of new technology. In 
2009,  we  began  a  pilot  project  with  six  charging  stations  for  
electric vehicles (EV) and a handful of EV owners. By 2013, MGE 
had installed 27 charging stations and enrolled about 190 EV owners 
in our program.

Our customers also are interested in compressed natural gas (CNG) 
to fuel vehicles. MGE works with customers looking to switch to 
CNG vehicles, which can provide significant savings in money and 
emissions compared to gasoline or diesel. CNG fueling sites are 
expanding locally and nationally. MGE is ready to serve the electric 
and natural gas-fueled vehicle markets and support customers who 
are choosing alternative vehicles.

Healthy economy

MGE is a full partner in our area’s economic development efforts. 
Working with others, we help support and grow local businesses. 
For example, the MGE Innovation Center is a business incubator 
at the University Research Park. Forbes magazine listed the center 
and research park as one of the 12 business incubators that are 
“changing the world.” Since 1989, the MGE Innovation Center has 
helped more than 70 start-up companies.

Energy investments, expansions

At MGE, we are taking our generation fleet to a new level of 
environmental performance.

MGE has added renewable generation and made considerable 
investments modernizing our generation fleet to reduce emissions. 
Since 2005, we have increased the capacity of our generation fleet 
by 43% by building new state-of-the-art power plants and by adding 
wind resources. We have invested $348 million in new generation 
that is cleaner, more efficient and meets or exceeds new environmental 
regulations. We also switched from coal to natural gas at our Blount 
Station and retired 90 megawatts of older, less efficient generation.

Now, at the Columbia Energy Center, we are investing $135 million 
in  a  major  emission  controls  project  due  for  completion  later  
in 2014.

In total, these capital expenditures are projected to be $483 million 
by the end of 2014.

As a result, in 2015, these combined investments in new generation 
and emission controls will significantly reduce our emissions. 
Compared to 2005, our improvements will lower sulfur dioxide 
emissions by 94%, nitrogen oxide emissions by 50% and mercury 
emissions by 88%.

More than 100 years of history 
The  first  stock  certificate 
issued by Madison Gas and 
Electric Co. in 1896. The equity 
value  of  the  company  was 
$400,000.

In 2013, Madison was ranked the sixth-strongest economy 
among the nation’s 366 metro areas, according to the economic 
research firm POLICOM. The high-tech sector plays a key 
role in keeping our economy strong. More than 600 high-tech 
companies generate $6.6 billion in annual sales and employ 
approximately 32,000 in bioscience and information technology. 
In fact, the Brookings Institution listed Madison in 2013 as 
the fifth best U.S. city for high-tech jobs.

The  strong  local  economy  drives  the  market  for  new 
construction. Our vibrant downtown has a new central library 
and a rapidly growing residential housing market. In the 
surrounding communities, Promega’s new $100 million  
bio-manufacturing facility opened in Fitchburg, and the 
Verona-based health records company Epic Systems completed 
a $578 million campus expansion.

With gratitude

At MGE Energy, we are grateful for the opportunity to serve. 
And, we are grateful for the confidence and support from you, 
our loyal shareholders.

Gary J. Wolter 
Chairman, President and  
Chief Executive Officer 

Giving thanks to past leaders 
who have guided our company

Our company’s history stretches back 158 years—one year before 
Madison incorporated as a city. Madison Gas and Electric was 
formed in 1896 from earlier utility companies. We formed our 
holding company, MGE Energy, in 2002. 

This year, I want to recognize our company’s previous leaders. 
They established a tradition of fiscal responsibility and prudent 
governance that helped make us the company we are today. They 
stressed operational excellence and exceptional customer service. 
They put in place the strong fundamentals that continue to guide 
us today. 

Thank you to the past leadership of Madison Gas and Electric.

Shareholders

Thank you

MGE  Energy  is  investing  $135  million  in  the 
Columbia Energy Center’s new emission controls 
that are expected to be online in 2014. 

Thank you for sharing our stock  
with your families.

Many of our shareholders, like Henry and Mary Ann Zauner, pass 
on the ethic of saving and investing to future generations. Henry 
emigrated from Germany to Wisconsin in 1925 when he was just 
two years old. He served in the U.S. Navy during World War II and 
worked as a printer for more than 50 years.

“Grandpa Henry” died nine years ago. However, he left a legacy 
for his grandchildren—shares of MGE Energy stock. Henry and 
Mary Ann purchased stock when their first grandchild arrived and 
then for each of their next nine grandchildren. Mary Ann said her 
husband wanted to give the grandchildren something that would 
last. Henry’s ethic of investing endures. The most recent addition 
to  the  Zauner  family,  two-year-old  Waylon,  recently  became  
a shareholder.

Thank you for choosing our stock.

You have chosen to own MGE Energy stock. You have put your 
confidence in us to focus on our core utility business and to grow 
value for you over the long-term. We dedicate ourselves to being 
the best community energy company we can be. Thank you for 
supporting the investments we make to serve our community.

In the last decade, our assets have more than doubled as we have 
improved the environmental performance of our generation fleet 
and added distribution infrastructure to enhance reliability. These 
investments allow us to better serve the growing Madison area. 

A key metric is market capitalization—stock price times the number 
of shares outstanding—which measures a company’s value. Our 
market capitalization has paralleled our asset growth. In the last 
decade,  our  market  value  has  more  than  doubled  and  totaled  
$1.3 billion at the close of 2013.

because you recognize value, you give to others,

you invest for the future, you reinvest 

Giving Thanks

Thank you for  
investing in the future. 

Thank you for  
reinvesting your dividends. 

Our shareholders’ loyalty is notable. On average, MGE Energy 
investors, whose shares are registered in their names, hold shares 
for 13 years. Many MGE Energy investors retain their shares for 
decades. They recognize our value over time. MGE Energy’s total 
return grew 10% in the last decade. Total return is stock price 
appreciation combined with dividends.

Wes and Joan Roscoe of Madison have owned shares and reinvested 
their dividends since 1979. Wes first purchased stock 35 years ago 
at the recommendation of a coworker. While Wes himself is reluctant 
to give others investment advice, he tells people, “MGE Energy has 
been good to me.”

Most  of  our  registered  shareholders  choose  to  reinvest  their  
MGE Energy dividends back into the company. We appreciate  
this confidence.

MGE Energy has an unwavering commitment to paying solid 
dividends, which we have done for more than 100 consecutive years. 
In addition, we have increased the dividend investors receive for  
38 years in a row. 

MGE Energy is one of just four combination utilities nationwide to 
increase the dividend for 38 or more consecutive years. No other 
major utility in Wisconsin can match our history of consistent 
dividend increases. Our annual dividend paid per share has increased 
from $0.35 in 1975 to $1.07 in 2013. The amount of cumulative 
dividends paid from 1975 through 2013 totals $776 million.

Customers Thank you

MGE installed Wisconsin’s first public quick 
charger for electric vehicles (EV). The unit can 
charge an EV battery to 80% in less than 30 
minutes. The quick charging option now makes 
commuting longer distances more convenient 
for EV drivers.

Thank you for engaging with us  
so we can serve you best. 

Customers talk. We listen. Each year we engage with over 30,000 
customers at events, trade shows, presentations and workshops. Our 
customers express a diverse set of needs, and we work hard to meet 
them with new programming.

We work with local businesses as they make energy improvements. 
Some asked if we could provide energy programs for their employees. 
This collaboration led to a popular MGE program called Energy 
Breaks, a service we offer companies that want to educate their 
employees on ways they can use energy more efficiently.

Thank you for spurring us to develop 
new products and services. 

The Madison area is home to a leading research university, innovative 
businesses and a thriving creative class. Our customers want options 
and embrace new ideas. They push us to be at the forefront, such as 
leading with green energy. Our green pricing program has placed 
in the top 10 utility programs in the country in the National Renewable 
Energy Laboratory’s last four rankings.

Leaders in Madison’s Latino community suggested that we take our 
energy messages on the air. As a result, we started a regular program 
on the Spanish-speaking radio station LaMovida. We tailor our 
messages so they are culturally relevant, and we remind customers 
to use our Spanish-translated materials. As customers tell us what 
they need, we respond.

Our customers are often early adopters of new technology. We see 
this most recently with alternative-fuel vehicles that use electricity. 
To serve the electric vehicle (EV) market, we took the bold step  
of installing one of the nation’s first interconnected networks of  
EV charging stations. With 27 charging stations located throughout 
our community, people now have the option to “plug in” instead of 
“gas up.”

We also are helping customers learn about and access compressed 
natural gas (CNG). CNG is becoming an attractive and growing 
alternative to gasoline and diesel for our business and government 
customers who own and operate vehicle fleets. MGE reaches out to 
our customers with seminars, newsletters and meetings to explain 
the benefits of CNG.

because you spur us, you engage with us, 

you connect in new ways, you help us plan

Giving Thanks

Thank you for connecting with us  
in new ways.

Thank you for helping us plan  
to meet your needs.

Connecting with customers always has been important to us. What’s 
new is the incredible growth in online engagement. Our customers 
are looking for us online, and we are there to give them the information 
they need. 

At MGE, we think responsible energy planning involves an open 
dialogue with our customers. Fifteen years ago, we organized 
Community Energy Conversations so customers could advise us on 
how to plan our community’s energy future.

In 2013, we updated the “My Account” section of mge.com after 
working with customers. Thanks to their input, My Account makes 
it easier for customers to pay bills, reference energy use and sign 
up for programs and services like green power.

Customers also are teaching us how to connect through social media. 
Our New Green Challenge program engages African-American and 
Latino customers in learning how their families can live more 
sustainably. As they learn, they post their ideas and success stories 
on Facebook, extending their program experiences to their networks 
of friends and relatives. Visit facebook.com/TheNewGreenChallenge.

From these discussions, MGE formulated its Energy 2015 plan that 
balances reliability with environmental responsibility. Then we got 
to  work—significantly  increasing  wind  energy,  retiring  older 
facilities, bringing cleaner coal generation online and expanding 
our new technology demonstration projects. We met all of our Energy 
2015 goals ahead of schedule.

Today, collaboration continues as we work with customers to expand 
distributed generation resources. Our community energy grid has 
more than 350 local energy sources ranging from solar power to 
biogas. Our customers’ participation results in a cleaner energy 
future for us all.

computer with colleague Caroline Radaj. Warner 
keeps up to date with social media and other 
online avenues to reach customers.  

Since 2007, MGE customers Jean and Jonathan 
Patz  have  collected  solar  energy  on  their  
roof. Their photovoltaic installation also feeds 
clean renewable energy to MGE’s community 
energy grid.

Communities Thank you

The new Madison Central Library’s green roof is 
part  of  MGE’s  technology  demonstration 
program. The roof is covered with a plant called 
sedum that absorbs rainwater, reduces runoff 
and provides insulation. 

Thank you for joining us in supporting 
local economic growth.

Madison has a vibrant entrepreneurial spirit and strong local economy. 
MGE supports economic development in our community. In 1989, 
we helped establish the MGE Innovation Center—an incubator that 
has served more than 70 tech businesses. In 2008, we helped launch 
the Metro Innovation Center.

Now we are helping a new project called StartingBlock—a center 
for entrepreneurs to work together and collaborate. We also support 
the Forward Technology Festival. This Madison-based conference 
focuses on start-up businesses with high potential. Attendees can 
learn from each other how to transition ideas into commerce.

We invest in the Venture Debt Fund to provide loans to young 
technology companies. Through the fund, we have helped 21 new 
companies including PerBlue—an energetic mobile gaming company.

Thank you for giving us the opportunity 
to innovate and educate.  

We need to be ahead of the curve in understanding new technologies 
and their role in serving us all. MGE achieves this by working with 
community partners.

Our technology demonstration program has more than 30 different 
projects located throughout our area. We put new technologies to 
work to gain first-hand knowledge. Solar installations teach us how 
we can harness the sun in our climate. A green roof on the new 
Madison Central Library not only absorbs rainwater, it provides 
insulation. At our local zoo, a micro-cogeneration unit produces 
heat and electricity to warm the aviary.

We educate inside and outside the classroom. We installed photovoltaic 
panels at 11 schools to provide hands-on education for students and 
teachers. We also educate at public venues like the Madison Children’s 
Museum and the Aldo Leopold Nature Center, home to our interactive 
renewable energy exhibit.

because you give, you support, 

you partner, you work

Giving Thanks

Thank you for partnering with us  
to reach our customers.

Thank you for working with us  
to keep our communities vital. 

MGE is more than pipes and wires. We are a community energy 
company  with  deep  ties  to  those  we  serve.  Many  nonprofit 
organizations work to help us connect with and serve our customers. 
When we launched Community Energy Resource Fairs, we brought 
together  key  stakeholder  groups  who  provide  assistance  to 
disadvantaged families. These one-stop workshops offered financial 
literacy resources, social services, energy assistance and expertise.

Our partnerships with public libraries extend our reach throughout 
the entire community. MGE provides brochures, books and other 
resources. Most popular are our portable energy meters. Customers 
can take them home to check the energy use of appliances.

Working with area chambers of commerce helps us connect with 
local businesses. For example, the Latino Chamber of Commerce 
opens doors to the many thriving Latino businesses in our community. 
MGE is there to assist business start-ups with energy advice.

Throughout our area, many organizations work hard to improve the 
lives of residents. The MGE Foundation steps up to help support 
their work. We donate to a variety of institutions such as local 
hospitals, senior independent living centers, the urban league and 
many others providing assistance to those in need throughout  
the community.

To help promote environmental responsibility, we cofounded a local 
program called EnAct, which encourages community members to 
live more sustainably by creating neighborhood and workplace 
environmental action teams.

To develop new ways to grow business locally, we are supporting 
a different type of community. Sector67 is a nonprofit collaborative 
space  that  provides  opportunities  to  build  and  create  the  next 
generation of innovation—sparking new ideas in manufacturing, 
electronics, software and more.

our employee and company donations reached nearly $300,000.

Employees volunteer and share their experiences with others. At a 
recent employee event, we featured Big Brothers Big Sisters of Dane 
County where several employees volunteer. They described their 
connections to their “little brothers and little sisters,” which inspired 
other employees to also give their time and talent.

Employees also share their technical knowledge and expertise. 
Understanding how electric and natural gas systems work can be a 
real asset to volunteer fire departments. Our employees who serve 
for  volunteer  fire  districts  provide  first-hand  knowledge  for 
departments responding to a natural gas leak or an electrical fire.

Thank you for making us better.

At MGE, our employees look for the best ideas to improve our 
operations. The MGE Green Team is an example. Employees across 
the  company  lead  the  team,  which  integrates  environmental 
responsibility into our daily work. Our Green Team is marking its 
20th year. The State of Wisconsin’s Green Tier program recognizes 
companies with superior environmental performance. Through 
environmental initiatives like our Green Team, MGE has achieved 
the highest recognition level possible within the Green Tier program.

Safety is another area we strive to continuously improve. Employees 
at every level of our organization engage—from revising our safety 
manual to creating new and expanded safety programs. During an 
insurance safety review, MGE was recognized as a leader in employee 
safety protection. Our electric arc protection program involves 
worker training along with fire-resistant clothing. We constantly 
seek ways to advance the culture of safety at MGE.

you bring ideas, you serve

Giving Thanks

Thank you for bringing fresh ideas. 

Thank you for putting customers first.

MGE and its employees have a reputation for going above and 
beyond. Several years ago, when we were switching to an automated 
meter reading system, we had to order new meters for all customers. 
We discovered that the meters available on the market contained 
mercury. So we challenged the manufacturer to develop mercury-
free devices for us. The manufacturer produced what became the 
first mercury-free meters widely available in the nation.

More recently, we launched an innovative program to extend natural 
gas service into rural areas. This program makes it more affordable 
for new customers to switch to affordable natural gas. 

Customer service is not just a slogan at MGE. We “walk the walk,” 
not just “talk the talk.” We understand it is the attention to detail 
that makes a difference.

One of our customers thanked an electric crew after they replaced 
a transformer. It’s a routine job for us, but not for Steve Dahlgren 
and his family who were concerned about their saltwater fish tank 
and potential damage to their yard. Said Steve, “I never even saw 
the crew take a break in the 10 degree weather. They helped with a 
generator to keep my fish alive. They replaced everything when they 
were done. Please pass along my gratitude for their great work!”

We turned to the community when adding new line technicians. We 
created a program with classroom and on-the-job training and 
recruited potential new employees from the Madison area. Our 
program  improved  employee  retention  and  provided  working 
experience on our electric distribution system.

We work to continuously improve the experiences customers have 
when they do business with us—from calling with questions, to 
searching for information on our website, to checking our outage 
map when the lights go out. Our employees dedicate themselves to 
serving our customers in the best possible way.

Ryan Krause is one of the employees that earned 
the rank of line technician journeyman after 
completing MGE’s on-the-job training program. 

Krista Strassman is one of MGE’s customer 
service  representatives  who  ensures  our 
customers have a positive experience when they 
call our company.

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 economic conditions, 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," "will," and other similar words generally identify forward-looking statements. Both 
MGE Energy and MGE caution investors that these forward-looking statements are subject to known and unknown 
risks and uncertainties that may cause actual results to differ materially from those projected, expressed, or implied.  

The factors that could cause actual results to differ materially from the forward-looking statements made by a registrant 
include (a) those factors discussed in Item 1A. Risk Factors, Item 7. Management's Discussion and Analysis of 
Financial Condition and Results of Operations, and Item 8. Financial Statements and Supplementary Data, Footnote 18. 
Commitments and Contingencies, and (b) other factors discussed herein and in other filings made by that registrant with 
the SEC. 

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

Stock Split

On December 20, 2013, MGE Energy's Board of Directors declared a three-for-two stock split of MGE Energy's 
outstanding shares of common stock, effective in the form of a stock dividend. Shareholders of record at the close of 
business on January 24, 2014, received one additional share of MGE Energy common stock for every two shares of 
common stock owned on that date. The additional shares were distributed on February 7, 2014. All share and per share 
data provided in this report give effect to this stock split. 

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 sec.gov, MGE Energy's 
website at mgeenergy.com, and MGE's website at mge.com. Copies may be obtained from our websites free of charge.

PART I. 

Item 1. Business.

MGE Energy operates in the following business segments: 

(cid:120)

(cid:120)

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

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

(cid:120) Nonregulated energy operations – owning and leasing electric generating capacity that assists MGE through 

MGE Energy's wholly owned subsidiaries MGE Power Elm Road and MGE Power West Campus.  

(cid:120)

Transmission investments – representing our investment in American Transmission Company LLC, a company 
engaged in the business of providing electric transmission services primarily in Wisconsin. 

(cid:120) All other – investing in companies and property that relate to the regulated operations and financing the regulated 

operations, through its wholly owned subsidiaries MAGAEL, CWDC, NGV Fueling Services, North Mendota, and 
Corporate functions. 

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

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

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

MGE Energy was organized as a Wisconsin corporation in 2001. MGE was organized as a Wisconsin corporation in 
1896. Their principal offices are located at 133 South Blair Street, Madison, Wisconsin 53788, 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, 2013, MGE supplied electric service to approximately 141,000 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 
2013, 2012, and 2011 were comprised of the following:

MGE is registered with a regional entity, The Midwest Reliability Organization. The essential purposes of this entity are 
the development and implementation of regional and NERC reliability standards; and determining compliance with 
those standards, including enforcement mechanisms. 

Transmission

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

Regional Transmission Organizations

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

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

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

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

Fuel supply and generation

MGE satisfies its customers' electric demand with internal generation and purchased power. During the years ended 
December 31, 2013, 2012, and 2011, 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 31% (245 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 from the Powder River Basin coal fields 
located in Wyoming. The coal inventory supply for the Columbia units decreased from approximately 37 days on 
December 31, 2012, to approximately 28 days on December 31, 2013.  

MGE Power Elm Road and two other owners own undivided interests in the coal-fired Elm Road Units in Oak Creek, 
Wisconsin, which accounts for 14% (106 MW) of MGE's net summer rated capacity. Power from this facility is shared 
in proportion to each owner's ownership interest. MGE Power Elm Road owns an 8.33% ownership interest in the Elm 
Road Units and its interest in the Elm Road Units is leased to MGE. The other owners are Wisconsin Energy 
Corporation, which operates the Units, and WPPI Energy, Inc. The Elm Road Units burn bituminous coal obtained from 
northern West Virginia and southwestern Pennsylvania, and Powder River Basin coal from Wyoming. MGE's share of 
the coal inventory supply for the Elm Road Units decreased from approximately 49 days on December 31, 2012, to 
approximately 40 days on December 31, 2013. 

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

Natural gas and oil
MGE owns gas fired combustion turbines. These turbines are primarily located in Madison and Marinette, Wisconsin 
and have a total of 154 MW of net summer rated capacity. 

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

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

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

Purchased power
MGE enters into short and long-term purchase power commitments with third parties to meet a portion of its anticipated 
electric energy supply needs. The following table identifies purchase power commitments at December 31, 2013, with 
unaffiliated parties for the next five years.

Gas Utility Operations

MGE transports and distributes natural gas in a service area covering 1,649 square miles in seven south-central 
Wisconsin counties. The service area includes the city of Madison, Wisconsin and surrounding areas. 

At December 31, 2013, MGE supplied natural gas service to approximately 147,000 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 2013, 2012, and 2011 were comprised of the following:

Gas operations accounted for approximately 31.0%, 26.3%, and 30.5% of MGE's total 2013, 2012, and 2011 regulated 
revenues, respectively. 

MGE can curtail gas deliveries to its interruptible customers. Approximately 20% of retail gas deliveries in both 2013 
and 2012 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 5,405,942 Dth of gas can be injected into ANR's storage fields in Michigan from April 1 through 
October 31. These gas supplies are then available for withdrawal during the subsequent heating season, November 1 
through March 31. Using storage allows MGE to buy gas supplies during the summer season, when prices are normally 
lower, and withdraw these supplies during the winter season, when prices are typically higher. Storage also gives MGE 
more flexibility in meeting daily load fluctuations. 

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

(cid:120)
(cid:120)

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

Nonregulated Energy Operations

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

Elm Road

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

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

WCCF

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

10 

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

Transmission Investments

American Transmission Company 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 as required by Wisconsin law. That interest is presently held by MGE Transco, which is jointly owned by 
MGE Energy and MGE. At December 31, 2013, MGE Transco held a 3.6% ownership interest in ATC. 

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

Environmental

MGE Energy and MGE are 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 they conduct their operations, the costs of those operations, as well as 
capital and operating expenditures. Regulatory initiatives, proposed rules, and court challenges to adopted rules, have 
the potential to have a material effect on our capital expenditures and operating costs. In addition to the regulations 
discussed below, MGE continues to track state and federal initiatives such as potential changes to regulations governing 
polychlorinated biphenyl (PCB), potential changes to regulations governing coal-combustion byproducts, and potential 
climate change legislation.   

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 is in compliance with the 2015 requirement. The costs to comply with the Act and its 
accompanying regulations are being recovered. 

Air Quality

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

Vacation of EPA's Cross State Air Pollution Rule (CSAPR) and Reinstatement of the Clean Air Interstate Rule (CAIR)
In 2005, the EPA promulgated the Clean Air Interstate Rule (CAIR) to reduce ozone and fine particulate matter 
emissions by reducing nitrogen oxide (NOx) and sulfur dioxide (SO2) emissions. NOx and SO2 interact in the 
atmosphere to form ambient ozone and fine particulate matter pollution from NOx and/or SO2. The CAIR generally 
requires NOx and SO2 emission reductions from fossil fuel-fired EGUs (25 MW or greater) in the eastern half of the 
United States in two phases and includes a regional cap-and-trade system. Phase I (currently in place) requires annual 
regional emission reductions from 2003 levels of 55% for NOx and 40% for SO2. Phase II begins in 2015 and requires 
regional NOx and SO2 emissions reductions from 2003 levels to 65% and 70%, respectively. MGE owns or has partial 
ownership in several generation units currently subject to the CAIR: Blount, Columbia, Elm Road Units, and its 
combustion turbines located in West Marinette and Fitchburg. 

In December 2008, the U.S. Court of Appeals for the D.C. Circuit remanded the CAIR to the EPA with directions to 
revise or replace the rule. The Court's remand order directed that the CAIR remain in effect until the EPA promulgated 
a replacement rule. The Court's order did not include a deadline for the EPA to act. 

11 

 
In August 2011, the EPA responded to the remand of the CAIR by promulgating the Cross State Air Pollution Rule 
(CSAPR). In August 2012, a federal appellate court vacated CSAPR and instructed the EPA to continue administering 
the CAIR pending finalizing a valid alternative program to control interstate pollution. That appellate decision was 
argued before the U.S. Supreme Court in December 2013, and a decision from that Court is pending. Thus, at this time, 
the CAIR remains effective. 

MGE is currently in compliance with the CAIR Phase I requirements. In addition, MGE will be able to meet Phase II 
NOx emissions reductions through using our NOx allowances provided under the rule, and we will meet Phase II SO2
emissions reductions through installation of pollution controls. New SO2 controls at Columbia are already underway 
and are planned to be completed by mid-2014. MGE expects that any costs incurred to meet Phase II of the CAIR will 
be fully recoverable through rates. MGE will monitor the Supreme Court's response to the CSAPR appeals and any 
subsequent actions by the EPA to continue to evaluate potential impacts to our operations. 

Global climate change

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

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

Climate Change Legislation

Federal Legislative Actions on Climate Change
Several bills and/or actions related to GHG regulation, including those to limit, prevent or delay the EPA's regulation of 
GHGs under the current Clean Air Act, have been proposed in both the House and the Senate. It is not anticipated that 
Congress will enact broad GHG reduction legislation in 2014. 

State and Regional Legislative Actions on Climate Change
It is not expected that the Wisconsin Legislature will enact broad GHG regulation in 2014. MGE continues to monitor 
legislative developments. 

Greenhouse Gas Regulation

President Obama's Executive Order Regarding Climate Change and his Directive to the EPA Regarding Power Sector 
Pollution Standards
In June 2013, President Obama introduced his "National Climate Action Plan." The plan consists of planned federal 
actions and directives to several federal agencies, including the EPA, on a range of activities and policies designed to 
reduce greenhouse gas emissions in the United States. See the GHG New Performance Standards discussion below for 
additional details. 

GHG New Source Performance Standards (NSPS) for New and Existing Electric Generating Units
In his June 2013 directive, President Obama instructed the EPA to re-propose greenhouse gas standards for new power 
plants, and to finalize those standards in a timely manner. The EPA published revised proposed standards for new 
power plants in September 2013, which would require, if finalized, that new coal-fired units and small natural gas units 
meet carbon dioxide emission levels significantly below current levels. 

The June 2013 directive also instructed the EPA to propose standards, regulations or guidelines for modified, 
reconstructed and existing power plants under Sections 111(b) and 111(d) of the Clean Air Act no later than June 2014 
and to finalize those standards by June 2015. The directive further instructs the EPA to require states to submit 
implementation plans for this rule by June 30, 2016.  

It is reasonable to assume that costs of implementation of these directives, when final rules are adopted, could be 
significant depending on the approach taken. We will continue to monitor the actions taken in response to the 
President's directives in 2014.

Columbia

Columbia is a coal-fired generating station operated by WPL in which WPL, WPSC, and MGE have ownership 
interests. In December 2009, the EPA sent a Notice of Violation (NOV) to MGE as one of the co-owners of Columbia. 
The NOV alleged that WPL and the Columbia co-owners failed to comply with appropriate pre-construction review and 
permitting requirements and, as a result, violated the Prevention of Significant Deterioration program requirements, 
Title V Operating Permit requirements of the CAA, and the Wisconsin SIP. In April 2013, the EPA filed a lawsuit 
against the co-owners of Columbia asserting similar allegations. In September 2010 and April 2013, the Sierra Club 
filed civil lawsuits against WPL alleging violations of the CAA at Columbia and other Wisconsin facilities operated by 
WPL. In June 2013, the court approved and entered a consent decree entered by the EPA, Sierra Club, and the co-
owners of Columbia to resolve these claims, while admitting no liability. One of the requirements of the consent decree 
requires installation of a SCR system at Columbia Unit 2 by December 31, 2018. Based on a preliminary estimate 
received by WPL, MGE's share of the projected cost for construction of the SCR system at Columbia is approximately 
$50-$60 million. See Footnote 18.d. of the Notes to Consolidated Financial Statements for additional information 
regarding this matter. 

Employees

As of December 31, 2013, MGE had 695 employees. MGE employs 211 employees who are covered by a collective 
bargaining agreement with Local Union 2304 of the International Brotherhood of Electrical Workers and 94 employees 
who are covered by a collective bargaining agreement with Local Union No. 39 of the Office and Professional 
Employees International Union. Both of these collective bargaining agreements expire on April 30, 2015. There are also 
5 employees covered by a collective bargaining agreement with Local Union No. 2006, Unit 6 of the United Steel, 
Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial, and Service Workers International Union. This 
collective bargaining agreement expires on October 31, 2015.

Item 1A. Risk Factors.

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

13 

 
Regulatory Risk

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

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

We could be subject to higher costs and potential penalties resulting from mandatory reliability standards.

MGE must adhere to mandatory reliability standards for its electric distribution system established by NERC. These 
standards cover areas such as critical infrastructure protection, emergency preparedness, facility design, and 
transmission operations, among others. The critical infrastructure protection standards focus on physical and access 
security of cyber assets, as well as incident response and recovery planning. MGE could be subject to higher operating 
costs in order to maintain compliance with the mandatory reliability standards, and any noncompliance could result in 
sanctions including monetary penalties. 

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

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

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

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

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

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

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

Operating Risk

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

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

We could be adversely affected by changes in the development, and utilization by our customers, of power generation 
and storage technology.

Developments in power generation and storage could affect our revenues and the timing of the recovery of our costs. 
Advancements in power generation technology, including commercial and residential solar generation installations and 
commercial micro turbine installations, are improving the cost-effectiveness of customer self-supply of electricity. 
Improvements in energy storage technology, including batteries and fuel cells, could also better position customers to 
meet their around-the-clock electricity requirements. Such developments could reduce customer purchases of electricity, 
but may not necessarily reduce our investment and operating requirements due to our obligation to serve customers, 
including those self-supply customers whose equipment has failed for any reason to provide the power they need. In 
addition, since a portion of our costs are recovered through charges based upon the volume of power delivered, 
reductions in electricity deliveries will affect the timing of our recovery of those costs and may require changes to our 
rate structures. 

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: 

(cid:120)

(cid:120)

(cid:120)

(cid:120)

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

The inability to transmit our contracted power from its generation source to our customers due to transmission line 
constraints, outages, or equipment failures, 

Reductions in the availability of power from our owned or contracted generation sources due to equipment failures, 
shortages of fuel or environmental limitations on operations, and  

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

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

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

Weather conditions, accidents, and catastrophic events, including terrorism and acts of sabotage or war, can result in 
damage or failures of equipment or facilities and disrupt or limit our ability to generate, transmit, transport, purchase, or 
distribute electricity and gas. Efforts to repair or replace equipment and facilities may take prolonged periods or may be 
unsuccessful, or we may be unable to make the necessary improvements to our operational system, causing service 
interruptions. The resulting interruption of services would result in lost revenues and additional costs. We are also  

15 

 
exposed to the risk of accidents or other incidents that could result in damage to or destruction of our facilities or 
damage to persons or property. Such issues could adversely affect revenues or increase costs to repair and maintain our 
systems. 

Our electricity and gas operations, as well as our confidential information, are subject to the risks of cyber attacks.

Our electricity and gas operations rely on sophisticated information technology systems and networks. Cyber attacks 
could disrupt or limit our electricity and gas operations, leading to potential lost revenues and additional costs. In 
addition, we may be required to incur significant development costs in order to strengthen the protection of our 
information technology systems and networks from outside attacks.  

Cyber attacks resulting in the theft, loss, or fraudulent use of customer, stockholder, employee, or proprietary data could 
result in litigation and/or monetary liability. In addition, our reputation could be adversely affected among customers, 
stockholders, regulators, and others as a result of a cyber attack. 

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

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

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

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

Financial Risk

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

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

We are exposed to interest rate risk. 

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

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

Prevailing interest rates affect our assessment and determination of discount rates that are a key assumption in the 
determination of the costs and funding of our defined benefit pension plans and may impact the amount of expense and 
timing of contributions to those plans. The performance of the capital markets affects the values of the assets that are 
held in trust to satisfy the future obligations under our pension and postretirement benefit plans. We have significant 
obligations in these areas and hold significant assets in these trusts. A decline in the market value of those assets may  

16 

 
increase our current and longer-term funding requirements for these obligations. Changes in the value of trust fund 
assets may affect the level of required contributions to these trusts to meet benefit obligations. Reduced benefit plan 
assets could result in increased benefit costs in future years and may increase the amount and accelerate the timing of 
required future funding contributions.  

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

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

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

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

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

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

General economic conditions may affect our operating revenues 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.  

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

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

things, the operating and physical conditions of the units. 

(2)  Baseload generation. 

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

Columbia, and WPSC. 

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

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

Corporation, which operates the units, and WPPI Energy, Inc. MGE leases the electric generating assets owned by 
MGE Power Elm Road. Amounts shown represent MGE's share of the net summer rated capacity of the Units.  

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

(7)  These facilities are owned by MGE. 

(8)  Nameplate capacity rating is 11 MW. 

(9)  Nameplate capacity rating is 30 MW. 

Electric and Gas Distribution Facilities

At December 31, 2013, MGE owned 890 miles of overhead electric distribution line and 1,157 miles of underground 
electric distribution cable, all of which are located in Wisconsin. These electric distribution facilities are connected by 
approximately 45 substations, installed with a capacity of 1,244,550 kVA. MGE's gas facilities include 2,536 miles of 
distribution mains, which are all owned by MGE. 

18 

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

Encumbrances

The principal plants and properties of MGE are subject to the lien of its Indenture of Mortgage and Deed of Trust dated 
as of January 1, 1946, as amended and supplemented, under which MGE's first mortgage bonds are issued. As of 
December 31, 2013, there were $1.2 million of first mortgage bonds outstanding. See Footnote 9 of Notes to 
Consolidated Financial Statements for additional information regarding MGE's first mortgage bonds. 

MGE Power Elm Road has collaterally assigned its right to lease payments from MGE for the Elm Road Units in order 
to secure the repayment of $70.6 million of senior secured notes issued by MGE Power Elm Road. See Footnote 9 of 
Notes to Consolidated Financial Statements for additional information regarding these senior notes. 

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

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

Dividend Restrictions

Dividend payments by MGE to MGE Energy are subject to restrictions arising under a PSCW rate order and, to a lesser 
degree, MGE's first mortgage bonds. The PSCW order restricts any dividends that MGE may pay MGE Energy if its 
common equity ratio, calculated in the manner used in the rate proceeding, is less than 55%. MGE's thirteen month 
rolling average common equity ratio at December 31, 2013, is 57.6%, as determined under the calculation used in the 
rate proceeding. MGE paid cash dividends of $25.0 million to MGE Energy in 2013. The rate proceeding calculation  

20 

 
includes as indebtedness imputed amounts for MGE's outstanding purchase power capacity payments and other PSCW 
adjustments, but does not include the indebtedness associated with MGE Power Elm Road and MGE Power West 
Campus, which are consolidated into MGE's financial statements but are not direct obligations of MGE. 

MGE has covenanted with the holders of its first mortgage bonds not to declare or pay any dividend or make any other 
distribution on or purchase any shares of its common stock unless, after giving effect thereto, the aggregate amount of 
all such dividends and distributions and all amounts applied to such purchases, after December 31, 1945, shall not 
exceed the earned surplus (retained earnings) accumulated subsequent to December 31, 1945. As of December 31, 
2013, approximately $305.6 million was available for the payment of dividends under this covenant. 

Stock Split

On December 20, 2013, MGE Energy's Board of Directors declared a three-for-two stock split of MGE Energy's 
outstanding shares of common stock, effective in the form of a stock dividend. Shareholders of record at the close of 
business on January 24, 2014, received one additional share of MGE Energy common stock for every two shares of 
common stock owned on that date. The additional shares were distributed on February 7, 2014. Shareholders received 
cash in lieu of any fractional shares of common stock they otherwise would have received in connection with the 
dividend. All share and per share data provided in this report give effect to this stock split.

**  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. MGE Energy uses 
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 by MGE Energy pursuant to a 
registration statement that was filed with the SEC and is currently effective.

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

General

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

Regulated electric utility operations, conducted through MGE, 
Regulated gas utility operations, conducted through MGE, 

(cid:120)
(cid:120)
(cid:120) Nonregulated energy operations, conducted through MGE Power and its subsidiaries 
(cid:120)
(cid:120) All other, which includes corporate operations and services.  

Transmission investments, representing our equity investment in ATC, and  

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 141,000 customers in Dane County, Wisconsin, including the city of Madison, and purchases and 
distributes natural gas to approximately 147,000 customers in the Wisconsin counties of Columbia, Crawford, Dane, 
Iowa, Juneau, Monroe, and Vernon. 

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

Executive Overview

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

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

(cid:120) Weather, and its impact on customer sales of electricity and gas, 
(cid:120)
(cid:120)
(cid:120)
(cid:120)
(cid:120)
(cid:120)
(cid:120)

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

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

For the year ended December 31, 2013, MGE Energy's earnings were $74.9 million or $2.16 per share compared to 
$64.4 million or $1.86 per share for the same period in the prior year. MGE's earnings for the year ended December 31, 
2013, were $49.0 million compared to $40.8 million for the same period in the prior year.

Our net income during 2013 compared to 2012 primarily reflects the effects of the following factors: 

(cid:120)

Retail electric sales decreased 0.8% driven by a return to more normal weather in 2013 compared to unusually 
warm weather in 2012. The average temperature in July 2013 was 71.9 degrees compared to 79.7 degrees in 
July 2012. The decrease in sales was partially offset by $2.7 million (after tax) recognized in AFUDC equity related 
to the Columbia environmental project for the year ended December 31, 2013. 

(cid:120) Gas net income increased due to a 25.7% increase in gas sales reflecting higher customer demand due to a colder 

winter. Heating degree days (a measure for determining the impact of weather during the heating season) increased 
by 27.9% compared to the prior period. In addition, operating and maintenance expenditures decreased over the 
prior period. 

(cid:120) Higher nonregulated revenues primarily attributable to approved recovery in December 2012 of force majeure costs 

associated with the construction of the Elm Road Units. The recovery of the force majeure costs began in 2013. A 
portion of the recovery pertaining to periods prior to the PSCW order will only affect 2013.  

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

(cid:120) A 4.7% increase in retail electric revenues, driven by increased residential customer demand primarily as a result of 
warmer-than-normal weather. Cooling degree days (a measure for determining the impact of weather during the 
cooling season) increased by 31% compared to the prior period. 

(cid:120) A 5.5% decrease in gas sales reflecting lower customer demand due to a milder winter. Heating degree days 

decreased by 15% compared to the prior period.  

(cid:120) MGE has recognized $1.4 million (after tax) in AFUDC equity related to the Columbia environmental project for 

the year ended December 31, 2012. 

During 2013, the following events occurred: 

Stock Split: On December 20, 2013, MGE Energy's Board of Directors declared a three-for-two stock split of 
MGE Energy's common stock in the form of a stock dividend. The additional shares were distributed February 7, 2014 
to all shareholders of record as of January 24, 2014. All share and per share data provided in this report give effect to 
this stock split. 

Columbia Environmental Project: In early 2011, the PSCW authorized the construction of air emission reduction 
systems and associated equipment on Columbia Units 1 and 2. MGE's estimated share of the capital expenditures 
required to complete this project is approximately $135 million. As of December 31, 2013, MGE has accumulated 
$120.9 million (excluding carrying costs) related to its share of the project, which is reflected in the Construction Work 
in Progress balance on MGE Energy's and MGE's consolidated balance sheets. Of this amount, MGE has accumulated 
$60.9 million in 2013. MGE has recognized $2.7 million (after tax) in AFUDC equity related to this project for the year 
ended December 31, 2013. 

Credit Facilities: In late June 2013, we amended the existing credit facilities at MGE Energy and MGE to increase the 
aggregate commitments available thereunder to $50 million and $100 million, respectively, to extend the maturity date 
of each facility to July 31, 2017, and to lower the adders used in the determination of the interest rates applicable to 
credit extensions under those facilities. 

25 

 
Long-term Debt: In September 2013, MGE issued $30 million of its 3.09% senior notes and $15 million of its 3.29% 
senior notes. The notes will mature on September 15, 2023 and September 15, 2026, respectively. The proceeds of the 
notes were used and are expected to continue to be used to help finance the Columbia environmental project. In 
July 2013, MGE refinanced $40 million of long-term debt. 

During 2014, several items may affect us, including: 

2014 Rate Filing: In July 2013, the PSCW authorized MGE to freeze electric and natural gas rates at 2013 levels for 
2014. The order includes authorizing 100% AFUDC on the Columbia scrubber construction project and deferral of 
increased costs related to ATC and MISO Schedule 26 fees. As part of the rate freeze plan authorized by the PSCW, 
effective January 1, 2014, approximately $6.2 million associated with a 2012 fuel rule surplus credit will not be required 
to be refunded to customers and will be amortized in 2014. The fuel credit will accrue interest at MGE's weighted cost 
of capital. The authorized return on equity will remain unchanged at 10.3%. 

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, 
from which we derive approximately 45% 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, 
the Columbia owners, including MGE, resolved claims surrounding the alleged failure, among other things, to obtain 
necessary air permits and implement necessary emission controls associated with past activities at Columbia. See 
Columbia discussion in Footnote 18.d. in the Notes to Consolidated Financial Statements. 

Columbia Environmental Project: During 2014, our share of the capital expenditures associated with the Columbia 
environmental project will be approximately $14 million.  

Commodity Prices: Natural gas and purchased power prices have increased in the first part of 2014 as a result of the 
unusually cold weather. The commodity price changes may result in increased costs for the Company. The increased 
commodity prices are mitigated through certain regulatory mechanisms in the natural gas business (PGA) and electric 
business (fuel rules). See Item 7A. Commodity Price Risk for further information.  

Pension and Other Postretirement Benefit Costs: Costs for pension and other postretirement benefits are affected by 
actual investment returns on the assets held for those benefits and by the discount rate, which is sensitive to interest 
rates, used to calculate those benefits. Investment assets for MGE's pension and other postretirement benefits have 
experienced market declines through February 2014. Also, interest rates have declined since the end of the year that 
could cause discount rates used to value the pension and postretirement benefit obligations to decline. The change in the 
value of the plan assets and the change in the discount rate are not expected to have an impact on the income statement 
for 2014. However, these changes may increase benefit costs in future years. MGE expects any changes in the cost for 
employee benefit plans will be factored into future rate actions. 

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 $150 million 
for MGE Energy (including MGE) and $100 million for MGE to address our liquidity needs. As of December 31, 2013, 
there were no borrowings outstanding under our lines of credit. 

The following discussion is based on the business segments as discussed in Footnote 22 of the Notes to Consolidated 
Financial Statements.

Rates changes. Rate changes have resulted in $15.6 million of additional revenue in 2013 compared to the same 
period in the prior year. The change is primarily a result of an electric retail rate increase which was authorized by 
the PSCW. Effective January 1, 2013, the retail rate increased 3.8% or $14.9 million for electric retail customers. 
The increase in retail electric rates was driven by costs for new environmental equipment at Columbia, final 
construction costs for the Elm Road Units, transmission reliability enhancements, and purchased power costs. 

Volume. During the year ended December 31, 2013, there was a 0.8% decrease in total retail sales volumes 
compared to the same period in the prior year driven by a return to more normal weather in 2013 compared to 
unusually warm weather in 2012. 

Adjustments to revenues. The adjustments to revenues amount includes the elimination of carrying costs for the 
Elm Road Units and the WCCF that were collected in electric rates, which are recognized as nonregulated energy 
operating revenues in our Nonregulated Energy Operations segment.  

Electric fuel and purchased power

The expense for fuel for electric generation decreased $0.4 million or 0.9% during the year ended December 31, 2013, 
compared to the same period in the prior year. Internal electric generation costs decreased $1.1 million as a result of a 
2.5% decrease in the per-unit cost (largely due to lower Elm Road coal costs). Internal electric generated volume 
delivered to the system increased 1.6%, which resulted in $0.7 million of increased expense.  

27 

 
Excluding the fuel rules adjustments discussed below, purchased power expense increased $6.5 million during the year 
ended December 31, 2013, compared to the same period in the prior year. This increase in expense reflects an 
$8.9 million or 13.6% increase in per-unit cost of purchased power, partially offset by a $2.4 million or 3.6% decrease 
in the volume of power purchased from third parties.  

Based on PSCW fuel rules, MGE is required to defer electric fuel-related costs that fall outside a 2% cost tolerance band 
around the amount used in the most recent rate proceeding. Any fuel rules adjustments are reflected in purchased power 
expense. During the years ended December 31, 2013 and 2012, MGE's actual fuel costs fell below the lower end of this 
tolerance band, which resulted in MGE deferring $6.7 million and $6.2 million, respectively, in fuel-related cost savings 
to be returned to customers and MGE recording a corresponding increase in purchased power costs. Any over/under 
recovery of the deferred costs is determined on an annual basis and adjusted in future billings to customers. After 
combining the fuel rules adjustments with the actual savings discussed above, purchased power expense increased 
$7.0 million ($6.5 million increase discussed above plus $0.5 million fuel rules difference) during the year ended 
December 31, 2013, compared to the prior year.  

Electric operating and maintenance expenses

Electric operating and maintenance expenses increased $1.2 million during the year ended December 31, 2013, 
compared to the same period in 2012. The following changes contributed to the net change: 

(In millions)
Increased transmission costs .............................................. $

For the year ended December 31, 2013, increased transmission costs are primarily due to an increase in transmission 
reliability enhancements, increased production costs are primarily due to increased costs at Columbia, and increased 
distribution costs are primarily due to increased conversion and overhead line maintenance expenses. The increase in 
costs was partially offset by decreased administrative and general costs which are primarily due to decreased pension 
costs.

Volume. For the year ended December 31, 2013, retail gas deliveries increased 27.1% compared to the same period 
in 2012, as a result of colder weather during the winter months compared to milder weather in the prior year. 

Rate changes. The average retail rate per therm for the year ended December 31, 2013, increased 2.3% compared to 
the same period in 2012, reflecting higher natural gas commodity costs. 

Cost of gas sold

For the year ended December 31, 2013, cost of gas sold increased by $29.2 million, compared to the same period in the 
prior year. The volume of purchased gas increased 27.4%, which resulted in $21.4 million of increased expense. In 
addition, the cost per therm of natural gas increased 7.8%, which resulted in $7.8 million of increased expense. 

Gas operating and maintenance expenses

Gas operating and maintenance expenses decreased $2.7 million for the year ended December 31, 2013, compared to 
the same period in 2012. The following changes contributed to the net change.

For the year ended December 31, 2013, decreased administrative and general costs are primarily due to decreased 
pension costs, and decreased customer service costs are primarily due to lower energy conservation spending. 

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

For the year ended December 31, 2013, other income, net for the electric and gas segments increased by $1.7 million, 
compared to the same period in the prior year primarily related to AFUDC equity recognized on the Columbia 
environmental project. 

Nonregulated Energy Operations - MGE Energy and MGE

For the years ended December 31, 2013 and 2012, net income at the nonregulated energy operations segment was 
$20.7 million and $18.1 million, respectively. The nonregulated energy operations are conducted through 
MGE Energy's subsidiaries: MGE Power Elm Road and MGE Power West Campus which have been formed to own 
and lease electric generating capacity to assist MGE. 

Results for the years ended December 31, 2013, reflect the recovery of force majeure costs associated with the 
construction of the Elm Road Units. In December 2012, as part of WEPCO's (the operator and primary owner of the 
Elm Road Units) 2013 Wisconsin rate case, the PSCW determined that 100% of the construction costs for the Elm Road 
Units were prudently incurred, and approved the recovery in rates of more than 99.5% of these costs. The recovery of 
the force majeure costs began in 2013. A portion of the recovery pertaining to periods prior to the PSCW order will only 
affect 2013.

Transmission Investment Operations - MGE Energy and MGE

Transmission investment other income

For the years ended December 31, 2013 and 2012, other income at the transmission investment segment was 
$9.4 million and $9.1 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. of the Notes to Consolidated Financial Statements 
for additional information concerning ATC and summarized financial information regarding ATC. 

Consolidated Income Taxes - MGE Energy and MGE

Both MGE Energy's and MGE's effective income tax rate for the years ended December 31, 2013 and 2012, was 37.5% 
and 37.7%, respectively.  

For 2011 tax return purposes, MGE Energy and MGE changed their income tax method of accounting for electric 
transmission and distribution repairs and accounting for depreciation. The 2012 financial statement impact pertaining to 
finalization of the electric transmission and distribution repairs is an increase to deferred tax expense and a 
corresponding decrease in the current tax provision in the amount of $4.8 million. The 2012 financial statement impact 
pertaining to finalization of the depreciation adjustment is an increase to deferred tax expense and a corresponding 
decrease in the current tax provision in the amount of $38.6 million. 

Noncontrolling Interest, Net of Tax - MGE

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

Rates changes. Rate changes have resulted in $19.0 million of additional revenue in 2012 compared to the same 
period in the prior year. The change is primarily a result of an electric retail rate increase which was authorized by 
the PSCW. Effective January 1, 2012, the retail rate increased 4.3% or $15.7 million for electric retail customers. 
The increase in electric rates was driven by MGE's electric fuel and purchased power costs, increased transmission 
costs, an update to the Elm Road Units' costs, and an increase for energy efficiency programs. Other factors also 
contributed to the revenue increase over the prior year, including customer mix (sales to various customer classes), 
demand charges, and customer fixed charges.  

Volume. During the year ended December 31, 2012, there was a 0.3% decrease in total retail sales volumes 
compared to the same period in the prior year, reflecting decreased industrial customer demand, offset in part by an 
increase in residential demand. 

Adjustments to revenues. The adjustments to revenues amount includes the elimination of carrying costs for Elm 
Road Units and WCCF that were collected in electric rates, which are recognized as nonregulated energy operating 
revenues in our Nonregulated Energy Operations segment.  

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

Electric fuel and purchased power

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

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

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

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

Electric depreciation expense

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

income reflects our equity in the earnings of ATC. See Footnote 4.b. for additional information concerning ATC and 
summarized financial information regarding ATC. 

Consolidated Other General Taxes - MGE Energy and MGE

MGE Energy's and MGE's other general taxes increased $1.0 million or 5.9% for the year ended December 31, 2012, 
when compared to the same period in 2011, partially due to increased Wisconsin license fee tax. The annual license fee 
tax expense is based on the prior year's adjusted operating revenues. Tax rates have not changed. 

Consolidated Income Taxes - MGE Energy and MGE

MGE Energy's effective income tax rate for the year ended December 31, 2012, was 37.7% compared to 37.1% for the 
same period in 2011, and MGE's effective income tax rate for the year ended December 31, 2012, was 37.7% compared 
to 37.0% for the same period in 2011. The effective income tax rate differences for both MGE Energy and MGE are 
primarily due to a lower estimated domestic manufacturing deduction. 

For 2011 tax return purposes, MGE Energy and MGE changed their income tax method of accounting for electric 
transmission and distribution repairs and accounting for depreciation. The 2012 financial statement impact pertaining to 
finalization of the electric transmission and distribution repairs is an increase to deferred tax expense and a 
corresponding decrease in the current tax provision in the amount of $4.8 million. The 2012 financial statement impact  

33 

 
pertaining to finalization of the depreciation adjustment is an increase to deferred tax expense and a corresponding 
decrease in the current tax provision in the amount of $38.6 million. 

Noncontrolling Interest, Net of Tax - MGE

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

During the year ended December 31, 2013, MGE issued $85.0 million of long-term debt, which was used to retire 
$40.0 million of long-term debt and to assist with the funding for the Columbia environmental project. During the year 
ended December 31, 2012, MGE issued and retired $28.0 million of long-term debt. 

Distributions to parent from noncontrolling interest, which represent distributions from MGE Power Elm Road and 
MGE Power West Campus, were $27.4 million for the year ended December 31, 2013, compared to $23.5 million in the 
prior year.  

2012 vs. 2011

During the year ended December 31, 2012, cash used for MGE's financing activities was $45.2 million compared to 
$54.6 million of cash used for MGE's financing activities in the prior year.  

Dividends paid from MGE to MGE Energy were $20.4 million for the year ended December 31, 2012, compared to 
$26.6 million in the prior year.  

During the year ended December 31, 2012, MGE issued and retired $28.0 million of long-term debt. During the year 
ended December 31, 2011, MGE Power Elm Road issued $30.0 million of long-term debt.  

Distributions to parent from noncontrolling interest decreased $29.0 million for the year ended December 31, 2012. As 
a result of long-term debt financing by MGE Power Elm Road, distributions to parent from noncontrolling interest were 
$43.0 million for the year ended December 31, 2011. The proceeds from the financing were used to repay MGE Energy, 
which had been using its short-term credit facilities to help finance the Elm Road Units. 

In addition, for the year ended December 31, 2011, net short-term debt repayments were $3.5 million. 

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 restricts any dividends that MGE may pay MGE Energy if its 
common equity ratio, calculated in the manner used in the rate proceeding, is less than 55%. MGE's thirteen month 
rolling average common equity ratio at December 31, 2013, is 57.6% as determined under the calculation used in the 
rate proceeding. MGE was not restricted from paying cash dividends in 2013. Cash dividends of $25.0 million and 
$20.4 million were paid by MGE to MGE Energy in 2013 and 2012, respectively. The rate proceeding calculation 
includes as indebtedness imputed amounts for MGE's outstanding purchase power capacity payments and other PSCW 
adjustments, but does not include the indebtedness associated with MGE Power Elm Road and MGE Power West 
Campus, which are consolidated into MGE's financial statements but are not direct obligations of MGE. 

MGE has covenanted with the holders of its first mortgage bonds not to declare or pay any dividend or make any other 
distribution on or purchase any shares of its common stock unless, after giving effect thereto, the aggregate amount of 
all such dividends and distributions and all amounts applied to such purchases, after December 31, 1945, shall not 
exceed the earned surplus (retained earnings) accumulated subsequent to December 31, 1945. As of December 31, 
2013, approximately $305.6 million was available for the payment of dividends under this covenant.

July 31, 2017 

Borrowings under each credit agreement may bear interest at a rate that floats daily based upon a prime rate or at a rate 
fixed for a specified interest period based upon a LIBOR-based index, plus an adder. In the case of the LIBOR-based 
rates, the adder is based upon the senior unsecured credit rating for MGE and does not exceed 0.75%.  

The agreements require the borrower to maintain a ratio of consolidated debt to consolidated total capitalization not to 
exceed a maximum of 65%. The ratio calculation excludes assets, liabilities, revenues, and expenses included in MGE's 
financial statements as a result of the consolidation of VIEs, such as MGE Power Elm Road and MGE Power West 
Campus. At December 31, 2013, the ratio of consolidated debt to consolidated total capitalization for each of 
MGE Energy and MGE, as calculated under the credit agreements' covenant, were 39.5% and 38.2%, respectively. See 
Footnote 10 of Notes to Consolidated Financial Statements for additional information regarding the credit facilities. 

Capitalization Ratios

MGE Energy's capitalization ratios were as follows: 

Common shareholders' equity ................

*Includes the current portion of long-term debt.

Credit Ratings

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

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

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

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

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

Statements for further discussion of the long-term debt outstanding at December 31, 2013. 

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

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

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

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

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

The above amounts do not include any contributions for MGE's pension and postretirement plans. MGE does not expect 
to make contributions to the plans for 2014 or 2015. The contributions for years after 2015 are not yet currently 
estimated. 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. These contributions reflect amounts required by law and discretionary amounts. 

The above amounts do not include future voluntary capital calls to ATC. On January 31, 2014, MGE Transco made a 
voluntary $0.5 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.

Other Matters

Elm Road

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

The warranty periods for both of the Elm Road Units have expired. During 2013, WEPCO and Bechtel (the construction 
contractor for the Elm Road Units) were working through the outstanding warranty claims. The warranty claim for the 
costs incurred to repair steam turbine corrosion damage identified on both units was resolved through a binding 
arbitration in June 2013. Final acceptance of the Elm Road Units occurred in June 2013 after all requirements stated in 
the contract with Bechtel were satisfied. 

ATC

On November 12, 2013, MISO and numerous other MISO transmission owners, including ATC, were named as 
respondents in a complaint filed at FERC. The complainants argue that the respondents' transmission rates are no longer 
just and reasonable "due to changes in the capital markets," and that the MISO base return on equity (ROE) should not 
exceed 9.15%, equity components of hypothetical capital structures should be restricted to 50%, and that relevant 
incentive ROE adders should be discontinued. MISO's base ROE is 12.38% and ATC's base ROE is 12.2%. MISO and 
the other MISO transmission owners filed a motion to dismiss the complaint. 

In April 2011, ATC and Duke Energy announced the creation of a joint venture, Duke-American Transmission 
Company (DATC), that seeks to build, own and operate new electric transmission infrastructure in North America to 
address increasing demand for affordable, reliable transmission capacity. DATC has announced various transmission 
projects to be constructed over the next 10 years. These projects are subject to approval by various regulatory agencies. 
At December 31, 2013, MGE Transco held a 3.6% ownership interest in ATC. Additional capital contributions by MGE 
Transco to ATC may be required. 

Critical Accounting Estimates - MGE Energy and MGE

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 
of America requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, 
revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our 
estimates, including those related to unbilled revenues, allowance for doubtful accounts, pension obligations, income  

41 

 
taxes, derivatives, and regulatory assets and liabilities. We base our estimates on historical experience and on various 
assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making 
judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Those 
values may differ from these estimates under different assumptions or conditions. We believe the following critical 
accounting estimates affect our more significant judgments used in the preparation of our consolidated financial 
statements. 

Unbilled Revenues

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

(cid:120)

(cid:120)

(cid:120)

The amount of electricity expected to be lost in the process of its transmission and distribution to customers (line 
loss) and the amount of electricity actually delivered to customers. 

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

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

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

Allowance for Doubtful Accounts

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

Pension and Other Postretirement Benefit Plans

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

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

(cid:120)

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 2013, MGE used an assumed return on assets of 8.10% for pension and 6.79% for other 
postretirement benefits. In 2014, the pension asset assumption will remain at 8.10%. MGE will increase the 
postretirement benefit assumption from 6.79% to 7.07% in 2014. The annual expected rate of return is based on 
projected long-term equity and bond returns, maturities and asset allocations. Holding other assumptions constant, 
for every 1% reduction in the expected rate of return on plan assets, annual pension and other postretirement cost 
would increase by approximately $2.7 million, before taxes. 

42 

 
(cid:120) 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. 

(cid:120) Medical trend assumptions. The health care cost trend rate is the assumed rate of increase in per-capita health care 

charges.

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

Income Tax Provision

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

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

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

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

Accounting for Derivative Instruments

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

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

Regulatory Assets/Liabilities

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

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

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

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

See Footnote 21 of the Notes to Consolidated Financial Statements for discussion of new accounting pronouncements.  

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

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

Commodity Price Risk

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

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

The fuel rules require the PSCW and Wisconsin utilities to defer electric fuel-related costs that fall outside a 
symmetrical cost tolerance band. Any over/under recovery of the actual costs is determined on an annual basis and will 
be adjusted in future billings to electric retail customers. Under the electric fuel rules, MGE is required to defer the 
benefit of lower costs if the actual electric fuel costs fall outside the lower end of the range and would defer costs, less 
any excess revenues, if the actual electric fuel costs exceeded the upper end of the range. Excess revenues are defined as 
revenues in the year in question that provide MGE with a greater return on common equity than authorized by the 
PSCW in MGE's latest rate order. The range is defined by the PSCW and has been modified throughout the years based 
on market conditions and other relevant factors. Currently, MGE is subject to a plus or minus 2% range. MGE assumes 
the risks and benefits of variances that are within the cost tolerance band. For 2013 and 2014, fuel and purchased power 
costs included in MGE's base fuel rates are $106.1 million. See Footnote 17 of the Notes to Consolidated Financial 
Statements for additional information. 

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

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

MGE has financial gas and electric commodity contracts to hedge commodity price risk in the gas and electric 
segments. These contracts are primarily comprised of exchange-traded option and future contracts. MGE also holds 
FTRs, which are used to hedge the risk of increased transmission congestion charges. At December 31, 2013, the fair 
value of these instruments exceeded their cost basis by $1.8 million. Under the PGA clause and electric fuel rules, MGE 
may include in the costs of fuel (natural gas or power) the costs and benefits of the aforementioned fuel price risk 
management tools. Because these costs/benefits are recoverable, the related unrealized loss/gain has been deferred on 
the consolidated balance sheet as a regulatory asset/liability. 

MGE has also entered into a ten-year purchased power agreement that provides MGE with firm capacity and energy 
that began on June 1, 2012, and ends on May 31, 2022 (the "base term"). The agreement also allows MGE an option to 
extend the contract after the base term. The agreement is considered a derivative contract and is recognized at its fair 
value on the consolidated balance sheet. However, the derivative qualifies for regulatory deferral and is recognized with 
a corresponding regulatory asset or liability depending on whether the fair value is in a loss or gain position. The fair 
value of the contract at December 31, 2013, reflects a loss position of $65.7 million. 

44 

 
Interest Rate Risk

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

Equity Price Risk - Pension-Related Assets

MGE currently funds its liabilities related to employee benefits through trust funds. These funds, which include 
investments in debt and equity securities, are managed by various investment managers. Changes in market value of 
these investments can have an impact on the future expenses related to these liabilities. Holding other assumptions 
constant, for every 1% reduction in the expected rate of return on plan assets, annual pension and other postretirement 
cost would increase by approximately $2.7 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 19.4% during the year 
ended December 31, 2013, and 14.5% during the year ended December 31, 2012. 

Credit Risk - Counterparty

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

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

Additionally, if a counterparty were to default and MGE were to liquidate all contracts with that entity, MGE's credit 
loss would include the loss in value of mark-to-market contracts; the amount owed for settled transactions; and 
additional payments, if any, to settle unrealized losses on accrual contracts. As of December 31, 2013, 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 1,649 square miles in Wisconsin. Based on results for the year ended 
December 31, 2013, no one customer constituted more than 10% of total operating revenues for MGE Energy and 
MGE. Credit risk for electric and gas is managed by MGE's credit and collection policies, which are consistent with 
state regulatory requirements. 

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.

Management's Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as 
such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of our 
management, including our principal executive officer and principal financial officer, we conducted an assessment of 
the effectiveness of our internal control over financial reporting based on the framework in the Internal Control - 
Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. 
Based on our assessment under the framework in the Internal Control - Integrated Framework (1992), our management 
concluded that our internal control over financial reporting was effective as of December 31, 2013. 

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.

The effectiveness of MGE Energy's internal control over financial reporting as of December 31, 2013, has been audited 
by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which 
appears herein.

Report of Independent Registered Public Accounting Firm

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

In our opinion, the consolidated financial statements listed in the index appearing under Item 15(a)(1) present fairly, in 
all material respects, the financial position of MGE Energy, Inc. and its subsidiaries at December 31, 2013 and 2012, 
and the results of their operations and their cash flows for each of the three years in the period ended December 31, 
2013, in conformity with accounting principles generally accepted in the United States of America. In addition, in our 
opinion, the financial statement schedules listed in the index appearing under Item 15(a)(2) present fairly, in all material 
respects, the information set forth therein when read in conjunction with the related consolidated financial statements. 
Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting 
as of December 31, 2013, based on criteria established in the Internal Control - Integrated Framework (1992) issued by 
the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is 
responsible for these financial statements and financial statement schedules, for maintaining effective internal control 
over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included 
in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to 
express opinions on these financial statements, on the financial statement schedules, and on the Company's internal 
control over financial reporting based on our integrated audits. We conducted our audits in accordance with the 
standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and 
perform the audits to obtain reasonable assurance about whether the financial statements are free of material 
misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our 
audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures 
in the financial statements, assessing the accounting principles used and significant estimates made by management, and 
evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included 
obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness 
exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. 
Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe 
that our audits provide a reasonable basis for our opinions. 

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

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

Notes to Consolidated Financial Statements
December 31, 2013, 2012, and 2011

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.  

On December 20, 2013, MGE Energy's Board of Directors declared a three-for-two stock split of 
MGE Energy's common stock in the form of a stock dividend. The additional shares were distributed 
February 7, 2014 to all shareholders of record as of January 24, 2014. All shares and per share data provided 
in this report give effect to this stock split. 

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, MGE Power, 
NGV Fueling Services, and North Mendota. MGE Power owns 100% of MGE Power Elm Road and MGE 
Power West Campus. MGE Power and its subsidiaries are part of MGE Energy's nonregulated energy 
operations, which were formed to own and lease electric generation projects to assist MGE. 

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

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

c.  Use of Estimates - MGE Energy and MGE.

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

57 

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

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

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

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

Cash amounts held by counterparties as margin for certain financial transactions are recorded as receivable – 
margin account. The balance is shown net of any collateral posted against derivative positions. As of 
December 31, 2013, there was $0.2 million collateral posted against derivative positions. As of 
December 31, 2012, there was no collateral posted against derivative positions. 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 1,649 square-miles in Wisconsin. MGE manages 
this concentration and the related credit risk through its credit and collection policies, which are consistent 
with state regulatory requirements. 

g. 

Inventories - MGE Energy and MGE.

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

SO2 emission allowances are included in inventory and are recorded at weighted average cost. These 
allowances are charged to fuel expense as they are used in operations. MGE's emission allowance balances 
as of December 31, 2013 and 2012, were $0.1 million. 

REC allowances are included in inventory and are recorded based on specific identification. These 
allowances are charged to purchase power expense as they are used in operations. MGE's REC allowance 
balances as of December 31, 2013 and 2012, were $0.6 million and $0.5 million, respectively. 

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

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

58 

 
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; and 
minor items are charged to maintenance expense. 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. Removal costs of utility property, less any salvage value, are adjusted through regulatory 
liabilities. Depreciation rates on nonregulated property are based on the estimated economic lives of the 
property. See Footnote 3 for further information. 

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

Electric
Gas
Nonregulated

2013 
2.7 % 
1.7 % 
2.3 % 

2012 
2.9 % 
1.7 % 
2.3 % 

2011 
3.2 % 
1.6 % 
2.3 % 

k.  Asset Retirement Obligations - MGE Energy and MGE.

MGE Energy and MGE are required to record a liability for the fair value of an ARO to be recognized in the 
period in which it is incurred if it can be reasonably estimated. The offsetting associated asset retirement 
costs are capitalized as a long-lived asset and depreciated over the asset's useful life. The expected present 
value technique used to calculate the fair value of ARO liabilities includes assumptions about costs, 
probabilities, settlement dates, interest accretion, and inflation. Revisions to the assumptions, including the 
timing or amount of expected asset retirement costs, could result in increases or decreases to the AROs. All 
asset retirement obligations are recorded as other long-term liabilities on our balance sheets. MGE has 
regulatory treatment and recognizes regulatory assets or liabilities for the timing differences between when 
we recover legal AROs in rates and when we would recognize these costs. See Footnote 19 for further 
information. 

l.  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. 

m.  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, 2013, MGE had over collected 
$1.7 million. At December 31, 2012, MGE had under collected $0.1 million. These amounts are netted in 
other current liabilities on the consolidated balance sheet. 

n.  Revenue Recognition - MGE Energy and MGE.

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

59 

 
o.  Utility Cost Recovery - MGE Energy and MGE.

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

p.  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. For both 2012 and 2011, as approved by the PSCW, MGE capitalized AFUDC-
debt and equity on 50% of applicable average construction work in progress at 8.36%. For 2013, MGE 
capitalized AFUDC-debt and equity on 50% of applicable average construction work in progress at 8.21%. 
For both 2012 and 2011, MGE received specific approval to recover 100% AFUDC on certain 
environmental costs for Columbia and 50% in 2013. Although the allowance does not represent current cash 
income, it is recovered under the ratemaking process over the service lives of the related properties. See 
Footnote 20 for further information regarding Columbia AFUDC.  

q.  Investments - MGE Energy and MGE.

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

r.  Capitalized Software Costs - MGE Energy and MGE.

Property, plant, and equipment includes the capitalized costs of internal use software totaling $20.9 million 
and $14.5 million at December 31, 2013 and 2012, respectively. During 2013 and 2012, MGE recorded 
$1.5 million and $1.3 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. 

s. 

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

MGE reviews plant and equipment and other property for impairment when events or changes in 
circumstances indicate that the carrying amount of the assets may not be recoverable. MGE's policy for 
determining when long-lived assets are impaired is to recognize an impairment loss if the sum of the 
expected future cash flows (undiscounted and without interest charges) from an asset are less than the 
carrying amount of that asset. If an impairment loss is recognized, the amount that will be recorded will be 
measured as the amount by which the carrying amount of the asset exceeds the fair value of the asset. There 
is no impairment of long-lived assets at December 31, 2013, 2012, and 2011. 

t. 

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.  

60 

 
Subsequent recognition, derecognition, and measurement is based on management's best judgment given the 
facts, circumstances, and information available at the reporting date. 

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

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

Excise taxes
MGE Energy, through its utility operations, pays a state license fee tax in lieu of property taxes on property 
used in utility operations. License fee tax is calculated as a percentage of adjusted operating revenues of the 
prior year. The electric tax rate is 3.19% for retail sales and 1.59% for sales of electricity for resale by the 
purchaser. The tax rate on sales of natural gas is 0.97%. The tax is required to be estimated and prepaid in 
the year prior to its computation and expensing. License fee tax expense, included in other general taxes, was 
$13.8 million, $13.5 million, and $12.9 million for the years ended December 31, 2013, 2012, and 2011, 
respectively.

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

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

Under two separate incentive plans, eligible participants, including employees and non-employee directors, 
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. Under the plans, these awards are subject to a prescribed vesting 
schedule and must be settled in cash. Accordingly, no new shares of common stock are issued in connection 
with the plans.  

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

See Footnote 14 for additional information regarding the plans. 

v.  Treasury Stock - MGE Energy.

Treasury shares are recorded at cost. Any shares of common stock repurchased are held as treasury shares 
unless cancelled or reissued. No treasury shares are held as of December 31, 2013. 

w.  Comprehensive Income - MGE Energy and MGE.

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

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 
hedge and on the type of hedge transaction. Derivative activities are in accordance with the company's risk 
management policy.  

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

2. 

Variable Interest Entities - MGE Energy and MGE.

a.  MGE Power Elm Road.

MGE Power Elm Road is not a subsidiary of MGE; however, it has been consolidated in the financial 
statements of MGE. MGE Power Elm Road was created for the purpose of owning new generating assets. Its 
sole principal assets are an undivided ownership interest in two 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 consolidated balance sheet related to its interest in this 
VIE: 

(In thousands)

Long-term debt consists of $70.6 million of senior secured notes that require that MGE Power Elm Road 
maintain a projected and actual debt service coverage ratio at the end of any calendar quarter of not less than 
1.25 to 1.00 for the trailing 12-month period. The debt is secured by a collateral assignment of lease 
payments that MGE is making to MGE Power Elm Road for use of the Elm Road Units pursuant to the 
related long-term leases. As of December 31, 2013, MGE Power Elm Road is in compliance with the 
covenant requirements. 

MGE has been and will continue to recover in rates the lease payments made to MGE Power Elm Road. 
MGE received approval from the PSCW to collect in rates the carrying costs incurred by MGE Power Elm 
Road. The total carrying costs on the Elm Road Units is $62.5 million. MGE is collecting carrying costs in 
rates over a six year period that began in 2010. Of these costs, $17.0 million relates to the capitalized interest 
and the debt portion of the units. These costs will be recognized over the period in which the generating units 
will be depreciated. The remaining $45.5 million represents the equity portion and is being recognized over 
the period allowed for recovery in rates.  

b.  MGE Power West Campus.

MGE Power West Campus is not a subsidiary of MGE; however, it has been consolidated in the financial 
statements of MGE. MGE Power West Campus was created for the purpose of owning new generating 
assets. Its 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.

Long-term debt consists of $49.7 million of senior secured notes that require that MGE Power West Campus 
maintain a projected debt service coverage ratio of not less than 1.25 to 1.00 and debt to total capitalization 
ratio of not more than .65 to 1.00. The debt is secured by a collateral assignment of lease payments that 
MGE is making to MGE Power West Campus for use of the cogeneration facility pursuant to the long-term 
lease. As of December 31, 2013, MGE Power West Campus is in compliance with the covenant 
requirements. 

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

c.  Other Variable Interest Entities.

MGE has a variable interest in entities through purchase power agreements relating to purchased energy 
from the facilities. As of December 31, 2013 and 2012, MGE had 61 megawatts and 65 megawatts, 
respectively, of capacity available under these agreements. MGE evaluated the variable interest entities for 
possible consolidation. The interest holder is considered the primary beneficiary of the entity and is required 
to consolidate the entity if the interest holder has the power to direct the activities that most significantly 
impact the economics of the variable interest entity. MGE examined qualitative factors such as the length of 
the remaining term of the contracts compared with the remaining lives of the plants, who has the power to 
direct the operations and maintenance of the facilities, and other factors, and determined MGE is not the 
primary beneficiary of the variable interest entities. There is not a significant potential exposure to loss as a 
result of involvement with these variable interest entities.

b.  ATC.

ATC owns and operates electric transmission facilities primarily in Wisconsin. MGE received an interest in 
ATC when it, like other Wisconsin electric utilities, contributed its electric transmission facilities to ATC as 
required by Wisconsin law. 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, 2013, 2012, and 2011, MGE Transco recorded equity earnings from the investment in 
ATC of $9.4 million, $9.1 million, and $8.6 million, respectively. Dividends received from ATC were 
$7.4 million, $7.1 million, and $6.7 million for the years ended December 31, 2013, 2012, and 2011, 
respectively. During the years ended December 31, 2013, 2012, and 2011, MGE Transco made $1.4 million, 
$2.1 million, and $0.9 million, respectively, in capital contributions to ATC. On January 31, 2014, MGE 
Transco made a $0.5 million capital contribution to ATC.  

At December 31, 2013 and 2012, 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, 2013 and 2012, 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.

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 31% (245 MW) of MGE's net summer rated capacity. Power from this 
facility is shared in proportion to each company's ownership interest. MGE has a 22% ownership interest in 
Columbia. The other owners are WPL, which operates Columbia, and WPSC. MGE's share of fuel, 
operating, and maintenance expenses for Columbia were $37.5 million, $36.3 million, and $37.1 million for 
the years ended December 31, 2013, 2012, and 2011, respectively. See Footnote 18 for discussion of MGE's 
future capital commitments in respect to the environmental projects at Columbia as a result of this ownership 
interest. 

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

b.  Elm Road.

MGE Power Elm Road owns an 8.33% ownership interest in each of two 615 MW coal-fired generating 
units in Oak Creek, Wisconsin, which accounts for 14% (106 MW) of MGE's net summer rated capacity. 
Unit 1 entered commercial operation on February 2, 2010. Unit 2 entered commercial operation on 
January 12, 2011. MGE Power Elm Road's sole principal asset is that ownership interest in those generating 
units. MGE Power Elm Road's interest in the Elm Road Units is leased to MGE pursuant to long-term leases. 

The remainder of the ownership interest in the Elm Road Units is held by two other entities, one of which is 
also responsible for the Units' operation. Each owner provides its own financing and reflects its respective 
portion of the facility and costs in its financial statements. MGE's share of fuel, operating, and maintenance 
expenses for the Elm Road Units were $13.4 million, $13.2 million, and $18.0 million for the years ended 
December 31, 2013, 2012, and 2011, respectively.

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

Asset Retirement Obligation 
See Footnote 19 for further discussion. 

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. 

In 2013, MGE issued long-term debt and used the net proceeds to redeem Medium-Term Notes and partially 
redeem Senior Notes. Included in the redemption prices were make-whole premiums totalling $6.8 million. The 
make-whole premiums are treated as a regulatory asset and will be amortized over the life of the long-term debt 
issued.

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

Elm Road
Costs associated with Elm Road are estimated in MGE's rates utilizing escrow accounting and include costs for 
lease payments, management fees, community impact mitigation, and operating costs. Also, MGE has deferred 
payments made to MGE Power Elm Road for carrying costs during construction of the facility. MGE is 
collecting carrying costs in rates over a six year period that began in 2010. All other costs are collected in rates 
over a one to two year period.  

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

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

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

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.  

67 

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

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

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

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

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

7. 

Common Equity.

a.  Common Stock - MGE Energy and MGE.

On December 20, 2013, MGE Energy's Board of Directors declared a three-for-two stock split of 
MGE Energy's outstanding shares of common stock, effective in the form of a stock dividend. Shareholders 
of record at the close of business on January 24, 2014 received one additional share of MGE Energy 
common stock for every two shares of common stock owned on that date. The additional shares were 
distributed on February 7, 2014. Shareholders received cash in lieu of any fractional shares of common stock 
they otherwise would have received in connection with the dividend. All share and per share data provided 
in this report give effect to this stock split. 

MGE Energy sells shares of its common stock through its Stock Plan. Those shares may be newly issued 
shares or shares that MGE Energy has purchased in the open market for resale to participants in the Stock 
Plan. All sales under the stock plan are covered by a shelf registration statement that MGE Energy filed with 
the SEC. For the years ended December 31, 2013 and 2012, MGE Energy did not issue any new shares of 
common stock under the Stock Plan.  

MGE Energy purchases 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.  

68 

 
During the years ended December 31, 2013 and 2012, MGE Energy paid $37.1 million (or $1.07 per share) 
and $36.0 million (or $1.04 per share), respectively, in cash dividends on its common stock. Dividends on 
common stock at MGE are subject to restrictions imposed by the PSCW and the covenants of MGE's 
outstanding first mortgage bonds. See Footnote 9 for further discussion of these covenants. During the years 
ended December 31, 2013 and 2012, MGE paid $25.0 million and $20.4 million, respectively, in cash 
dividends to MGE Energy.  

b.  Preferred Stock - MGE Energy and MGE.

MGE had 1,175,000 shares of $25 par value cumulative preferred stock authorized but unissued at 
December 31, 2011. In October 2012, MGE amended and restated its existing Restated Articles of 
Incorporation, which eliminated the previously authorized cumulative preferred stock. There were no shares 
of cumulative preferred stock authorized, issued, or outstanding at December 31, 2013 and 2012. 

c.  Dilutive Shares Calculation - MGE Energy.

MGE Energy does not hold any dilutive securities.

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

first mortgage bonds are issued. The Mortgage Indenture provides that dividends or any other 
distribution or purchase of shares may not be made if the aggregate amount thereof since December 31, 
1945 would exceed the earned surplus (retained earnings) accumulated subsequent to December 31, 
1945. As of December 31, 2013, approximately $305.6 million was available for the payment of 
dividends under this covenant. 

(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)  Unsecured notes issued pursuant to various Note Purchase Agreements with one or more purchasers. 

The notes are not issued under, or governed by, MGE's Indenture dated as of September 1, 1998, which 
governs MGE's Medium-Term Notes. 

(d)  On July 18, 2013, MGE issued $20 million in principal amount of 4.42% senior notes, Series A, due 

July 15, 2043 and $20 million in principal amount of 4.47% senior notes, Series B, due July 15, 2048. 
MGE used the net proceeds from the sale of the Notes to redeem on July 18, 2013, $20 million of its 
5.26% Medium-Term Notes due September 29, 2017, and to make a $20 million partial redemption of 
its 5.59% Senior Notes due September 11, 2018. MGE paid a redemption price equal to the principal 
amount of the notes that were redeemed, plus accrued interest to the redemption date, plus a make-
whole premium equal to $3.2 million and $3.6 million, for the 5.26% Medium-Term Notes due 
September 29, 2017 and 5.59% Senior Notes due September 11, 2018, respectively. The make-whole 
premiums are treated as a regulatory asset and will be amortized over the life of the Series A and 
Series B Notes. Any interest savings in 2013 will be deferred. There is $20 million principal amount of 
the 5.59% Senior Notes remaining outstanding after the redemption. 

70 

 
The Note Purchase Agreement under which the Series A and Series B Notes were issued also included 
the issuance on September 16, 2013, of $30 million in principal amount of 3.09% Senior Notes, 
Series C, due September 15, 2023 and $15 million of 3.29% Senior Notes, Series D, due September 15, 
2026. The Series C Notes and the Series D Notes carry interest rates of 3.09% per annum and 3.29% per 
annum, respectively. The proceeds of the Notes were used and are expected to continue to be used to 
help finance the Columbia environmental project. 

(e)  Issued by MGE. Under that Note Purchase Agreement: (i) note holders have the right to require MGE to 
repurchase their notes at par in the event of an acquisition of beneficial ownership of 30% or more of the 
outstanding voting stock of MGE Energy, (ii) MGE must maintain a ratio of its consolidated 
indebtedness to consolidated total capitalization not to exceed a maximum of 65%, and (iii) MGE 
cannot issue "Priority Debt" in an amount exceeding 20% of its consolidated assets. Priority Debt is 
defined as any indebtedness of MGE secured by liens other than specified liens permitted by the Note 
Purchase Agreement and certain unsecured indebtedness of certain subsidiaries. As of December 31, 
2013, MGE is in compliance with the covenant requirements. 

(f)  Issued by MGE Power West Campus. The Note Purchase Agreements require it to maintain a projected 
debt service coverage ratio of not less than 1.25 to 1.00, and debt to total capitalization ratio of not more 
than .65 to 1.00. The notes are secured by a collateral assignment of lease payments that MGE is making 
to MGE Power West Campus for use of its ownership interest in the West Campus Cogeneration 
Facility pursuant to a long-term lease. As of December 31, 2013, MGE Power West Campus is in 
compliance with the covenant requirements. 

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

maintain a projected and actual debt service coverage ratio at the end of any calendar quarter of not less 
than 1.25 to 1.00 for the trailing 12-month period. The notes are secured by a collateral assignment of 
lease payments that MGE is making to MGE Power Elm Road for use of its ownership interest in the 
Elm Road Units pursuant to long-term leases. As of December 31, 2013, MGE Power Elm Road is in 
compliance with the covenant requirements.

The agreement requires MGE Energy to maintain a ratio of its consolidated indebtedness to consolidated 
total capitalization not to exceed a maximum of 65%. A change in control constitutes a default under the 
agreement. Change in control events are defined as (i) a failure by MGE Energy to hold 100% of the 
outstanding voting equity interest in MGE or (ii) the acquisition of beneficial ownership of 30% or more of 
the outstanding voting stock of MGE Energy by one person or two or more persons acting in concert. As of 
December 31, 2013, MGE Energy is in compliance with the covenant requirements. 

b.  MGE.

For short-term borrowings, MGE generally issues commercial paper (issued at the prevailing discount rate at 
the time of issuance), which is supported by unused committed bank lines of credit. At December 31, 2013, 
MGE had an unsecured, committed revolving line of credit for $100 million expiring July 31, 2017. The 
agreement 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, 2013, no borrowings 
were outstanding under this facility.  

The agreement requires MGE to maintain a ratio of consolidated debt to consolidated total capitalization not 
to exceed a maximum of 65%. The ratio calculation excludes assets, liabilities, revenues, and expenses 
included in MGE's financial statements as the result of the consolidation of VIEs, such as MGE Power West 
Campus and MGE Power Elm Road. A change in control constitutes a default under the agreement. Change 
in control events are defined as (i) a failure by MGE Energy to hold 100% of the outstanding voting equity 
interest in MGE or (ii) the acquisition of beneficial ownership of 30% or more of the outstanding voting 
stock of MGE Energy by one person or two or more persons acting in concert. As of December 31, 2013, 
MGE is in compliance with the covenant requirements.

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

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

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

72 

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

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

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

At December 31, 2013 and 2012, the carrying amount of cash and cash equivalents approximates fair market 
value due to the short maturity of those investments and obligations. The estimated fair market value of 
MGE Energy's and MGE long-term debt is based on quoted market prices for similar financial instruments at 
December 31. Since long-term debt is not traded in an active market, it is classified as Level 2. The 
estimated fair market value of MGE Energy's and MGE's financial instruments are as follows:

No transfers were made in or out of Level 1 or Level 2 for the year ended December 31, 2013. 

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

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

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

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

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

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

The following table summarizes the changes in Level 3 assets and liabilities measured at fair value on a

As of December 31, 2013, MGE Energy did not have a federal net operating loss or tax credit carryforwards. 
As of December 31, 2012, MGE Energy had approximately $63.4 million and $3.4 million of net operating 
loss and tax credit carryforwards, respectively. The net operating loss and tax credit carryforwards resulted 
in deferred tax assets of $22.2 million and $3.4 million, respectively, as of December 31, 2012.  

76 

 
As of December 31, 2013, MGE did not have a federal net operating loss or tax credit carryforwards. As of 
December 31, 2012, MGE had approximately $64.2 million and $3.4 million of net operating loss and tax 
credit carryforwards, respectively. The net operating loss and tax credit carryforwards resulted in deferred 
tax assets of $22.5 million and $3.4 million, respectively, as of December 31, 2012. 

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

For tax purposes, as of December 31, 2013, both MGE Energy and MGE had approximately $4.0 million of 
Illinois state tax net operating loss deductions that expire between 2014 and 2024 if unused. 

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

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

A tabular reconciliation of unrecognized tax benefits and interest from January 1, 2011, to December 31, 
2013, is as follows:

Unrecognized tax benefits are liabilities shown with Other Deferred Liabilities on the December 31, 2013, 
and December 31, 2012, consolidated balance sheets. The interest component is offset by a regulatory asset. 

MGE Energy filed an application with its 2009 tax returns to change its income tax methods of accounting 
for electric generation, transmission and distribution repairs and its 2010 tax returns for gas distribution 
repairs. These method changes accelerated tax deductions for repairs in accordance with Treasury 
Regulations and case law, as compared to the prior method of claiming tax depreciation on project costs. 
During 2011, the IRS issued guidance on the treatment of electric transmission and distribution repairs. This 
guidance has prompted the reversal of a majority of the unrecognized tax benefits for these repairs. During 
2013, the IRS issued guidance on the treatment of electric generation repairs. This guidance prompted the 
reversal of the unrecognized tax benefits for these repairs. At December 31, 2013, MGE Energy and MGE 
have an unrecognized tax benefit in the amount of $2.4 million related to temporary tax differences 
associated with the change in income tax method of accounting for electric transmission and distribution 
repairs and gas distribution repairs. At December 31, 2012, MGE Energy and MGE had an unrecognized tax 
benefit in the amount of $3.2 million primarily related to temporary tax differences associated with the 
change in income tax method of accounting for electric generation, transmission, and distribution repairs and 
gas distribution repairs. At December 31, 2011, MGE Energy and MGE had an unrecognized tax benefit in 
the amount of $2.4 million primarily related to temporary tax differences associated with the change in 
income tax method of accounting for electric generation repairs and gas distribution repairs. There were no 
unrecognized tax benefits at December 31, 2013, or December 31, 2012, related to federal permanent 
differences and tax credits. Unrecognized tax benefits at December 31, 2011, related to federal permanent 
differences and tax credits were $0.2 million. 

77 

 
The unrecognized tax benefits at December 31, 2013, are not expected to significantly increase or decrease 
within the next twelve months. However, the IRS may issue guidance on the treatment of gas distribution 
repairs. In addition, statutes of limitations will expire for MGE Energy and MGE tax returns. The impact of 
the statutes of limitations expiring is not anticipated to be material. The following table shows tax years that 
remain subject to examination by major jurisdiction:

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

In March 2010, the Patient Protection and Affordable Care Act (the PPACA) was enacted. The PPACA 
effectively changes the tax treatment of federal subsidies paid to sponsors of retiree health benefit plans that 
provide a benefit that is at least actuarially equivalent to the benefits under Medicare Part D. As a result of 
the PPACA, these subsidy payments became taxable in tax years beginning after December 31, 2012. In 
2012, MGE was able to specifically identify assets within the retiree health benefit plans to be used for 
payment of future health insurance premiums and prescription drug coverage. This process will allow certain 
Medicare Part D subsidy receipts to be non-taxable. 

d.  Final Tangible Property Regulations.

In September 2013, the IRS and Treasury Department released final regulations under Section 162(a) and 
263(a) on the deduction and capitalization of expenditures related to tangible property, replacing the 2011 
temporary regulations issued in December 2011. The final regulations did not have a material impact on 
MGE Energy's and MGE's consolidated financial statements.  

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

MGE maintains qualified and nonqualified pension plans, health care, and life insurance benefits, and two 
defined contribution 401(k) benefit plans for its employees and retirees. MGE's costs for the 401(k) plans were 
$2.3 million, $2.1 million, and $1.8 million in 2013, 2012, and 2011, respectively. A measurement date of 
December 31 is utilized for all pension and postretirement benefit plans. 

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

The expected long-term rate of return on the pension plan assets is 8.10% for both 2013 and 2012.  

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. 

79 

 
The asset allocation for MGE's pension plans at the end of 2013 and 2012, and the target allocation for 2014, 
by asset category, follows: 

Equity securities .................................
Debt securities ....................................
Real estate ..........................................

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, 2013. 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, 2013, 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, 2013: 

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

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

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

80 

 
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:

g.  Other Postretirement Benefits.

The fair value of plan assets for the postretirement benefit plans is $37.6 million and $32.1 million at the end 
of 2013 and 2012, respectively. The expected long-term rate of return on these plan assets is 6.79% and 
7.26% for 2013 and 2012, respectively.  

Of the above amounts, $31.1 million and $25.0 million at the end of 2013 and 2012, 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.

MGE does not expect to make contributions to the plans for 2014 or 2015. The contributions for years after 
2015 are not yet currently estimated. MGE has adopted the asset smoothing as permitted in accordance with 
the Pension Protection Act of 2006, including modifications made by WRERA. 

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

In 2013, MGE made $34.8 million in employer contributions to its pension and postretirement plans.

Share-Based Compensation - MGE Energy and MGE.

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

On the grant date, MGE Energy and MGE measure the cost of the employee services received in exchange for a 
performance unit award based on the current market value of MGE Energy common stock. The fair value of the 
awards is re-measured quarterly, including at December 31, 2013, as required by applicable accounting 
standards. Changes in fair value as well as the original grant are recognized as compensation cost. Since this 
amount is re-measured throughout the vesting period, the compensation cost is subject to variability. These units 
are subject to a five year graded vesting schedule. Units have been adjusted to reflect the three-for-two stock split 
declared December 20, 2013.

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. 

During the year ended December 31, 2013, MGE recorded $1.5 million in compensation expense as a result of 
awards under the Performance Unit Plan. Compensation expense during both the years ended December 31, 2012 
and 2011 was $1.4 million. In January 2013, cash payments of $1.0 million were distributed relating to awards 
that were granted in 2008 and became payable under the Performance Unit Plan. No forfeitures occurred during 
the years ended December 31, 2013, 2012, and 2011. At December 31, 2013, $4.5 million of outstanding awards 
are vested, and of this amount no cash settlements have occurred. 

In December 2013, a Director Incentive Plan was approved for the non-employee members of the Board of 
Directors. This plan is similar to MGE Energy's Performance Unit Plan for eligible employees described above. 
Under the plan, a non-employee director can 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 
payments, at the end of the set performance period. The units are subject to a three year graded vesting schedule. 
In January 2014, unit awards of 4,683 (post-split) were granted to the non-employee Directors. For accounting 
purposes, the awards will be measured similarly to the employee unit awards.  

15.  Regional Transmission Organizations - MGE Energy and MGE.

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 $78.0 million reduction 
to sales to the market and purchase power expense for MISO markets for the year ended December 31, 2013, and 
a $75.9 million and $102.1 million reduction to sales to the market and purchased power expense for MISO and 
PJM markets for the years ended December 31, 2012 and 2011, respectively. 

84 

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

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

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

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

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

a.  Purpose.

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

b.  Notional Amounts.

The gross notional volume of open derivatives is as follows: 

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

December 31, 2013 
458,660 MWh 
3,750,000 Dth

December 31, 2012 
444,650 MWh 
1,980,000 Dth 
2,670 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. 

85 

 
MGE purchases and sells exchange-traded and over-the-counter options, swaps, and future contracts. These 
arrangements are primarily entered into to help stabilize the price risk associated with gas or power 
purchases. These transactions are employed by both MGE's gas and electric segments. Additionally, as a 
result of the firm transmission agreements that MGE holds on transmission paths in the MISO market, MGE 
holds FTRs. An FTR is a financial instrument that entitles the holder to a stream of revenues or charges 
based on the differences in hourly day-ahead energy prices between two points on the transmission grid. The 
fair values of these instruments are reflected as a regulatory asset/liability depending on whether they are in a 
net loss/gain position. Depending on the nature of the instrument, the gain or loss associated with these 
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, 2013 and 2012 the fair value of exchange 
traded derivatives and FTRs exceeded their cost basis by $1.8 million and $0.3 million, respectively. 

MGE is a party to a ten-year purchased power agreement that provides MGE with firm capacity and energy 
during a base term from June 1, 2012, through May 31, 2022. The agreement also allows MGE an option to 
extend the contract after the base term. The agreement is accounted for as a derivative contract and is 
recognized at its fair value on the consolidated balance sheet. However, the derivative qualifies for 
regulatory deferral and is recognized with a corresponding regulatory asset or liability depending on whether 
the fair value is in a loss or gain position. The fair value of the contract at December 31, 2013 and 2012, 
reflects a loss position of $65.7 million and $72.6 million, respectively. The actual fuel cost will be 
recognized in purchased power expense in the month of purchase. 

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

MGE's commodity derivative contracts, FTRs, and ten-year PPA are subject to regulatory deferral. These 
derivatives are marked to fair value and are offset with a corresponding regulatory asset or liability. Realized 
gains and losses are deferred on the consolidated balance sheet and are recognized in earnings in the delivery 
month applicable to the instrument. As a result of the above described treatment, there are no unrealized 
gains or losses that flow through earnings.  

The ten-year PPA has a provision that may require MGE to post collateral if MGE's debt rating falls below 
investment grade (i.e., below BBB-). The amount of collateral that it may be required to post varies from 
$20.0 million to $40.0 million, depending on MGE's nominated capacity amount. As of December 31, 2013, 
no collateral has been posted. Certain counterparties extend MGE a credit limit. If MGE exceeds these 
limits, the counterparties may require collateral to be posted. As of December 31, 2013 and 2012, no 
counterparties were in a net liability position.  

Nonperformance of counterparties to the non-exchange traded derivatives could expose MGE to credit loss. 
However, MGE enters into transactions only with companies that meet or exceed strict credit guidelines, and 
it monitors these counterparties on an ongoing basis to mitigate nonperformance risk in its portfolio. As of 
December 31, 2013, no counterparties have defaulted.  

17.  Rate Matters - MGE Energy and MGE.

a.  Rate Proceedings.

On July 26, 2013, the PSCW authorized MGE to freeze electric and natural gas rates at 2013 levels for 2014. 
The order includes authorizing 100% AFUDC on the Columbia scrubber construction project and deferral of 
increased costs related to ATC and MISO Schedule 26 fees. As part of the rate freeze plan authorized by the 
PSCW, effective January 1, 2014, approximately $6.2 million associated with a 2012 fuel rule surplus credit 
will not be required to be refunded to customers and will be amortized in 2014. The fuel credit will accrue 
interest at MGE's weighted cost of capital. The authorized return on equity will remain unchanged at 10.3%. 

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

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

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

b.  Fuel Rules.

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

As of December 31, 2013, MGE has deferred $6.7 million (to be returned to customers in a future period) of 
2013 electric fuel-related savings that are outside the range authorized by the PSCW.  

88 

 
18.  Commitments and Contingencies. 

a.  Purchase Contracts - MGE Energy and MGE.

MGE Energy and MGE have entered into various commodity supply, transportation, and storage contracts to 
meet their obligations to deliver electricity and natural gas to customers. As of December 31, 2013, the 
future minimum commitments related to these purchase contracts were as follows:

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

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

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

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

customer rates. 

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

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

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

MGE makes available to qualifying customers a financing program for the purchase and installation of 
energy-related equipment that will provide more efficient use of utility service at the customer's property. 
MGE is party to a chattel paper purchase agreement with a financial institution under which it can sell or 
finance an undivided interest with recourse, in up to $10.0 million of the financing program receivables, until 
July 31, 2014. At December 31, 2013, 2012, and 2011, respectively, MGE had sold a $5.4 million, 
$4.5 million, and $4.3 million interest in these receivables. MGE retains the servicing responsibility for these 
receivables. 

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

MGE maintains responsibility for collecting and remitting loan payments from customers to the financial 
institution and does not retain any interest in the assets sold to the financial institution. At December 31, 
2013, MGE had recorded a servicing asset of $0.3 million. At both December 31, 2012 and 2011, MGE had 
recorded a servicing asset of $0.2 million. MGE recognized a gain of $0.2 million for the year ended 
December 31, 2013, in connection with the sale of loan assets. MGE recognized gains of $0.1 million for 
each of the years ended December 31, 2012 and 2011, in connection with the sale of loan assets. The 
servicing asset amount amortized in 2013 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 2013, 2012,  

89 

 
and 2011, MGE received approximately $1.6 million, $1.2 million, and $1.5 million, respectively, from the 
financial institution for the sale of loan assets. During those same years, payments of $0.8 million, 
$1.2 million, and $0.8 million, respectively, were made by MGE to the financial institution. 

MGE would be required to perform under its guarantee if a customer defaulted on its loan. The energy-
related equipment installed at the customer sites is used to secure the customer loans. The loan balances 
outstanding at December 31, 2013, approximate the fair value of the energy-related equipment acting as 
collateral. The length of the MGE guarantee to the financial institution varies from one to ten years 
depending on the term of the underlying customer loan. Principal payments for the next five years on the 
loans are:

c.  Leases - MGE Energy and MGE.

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

Future minimum rental payments at December 31, 2013, under agreements classified as operating leases 
with noncancelable terms in excess of one year are as follows:

d.  Environmental - MGE Energy and MGE.

Water Quality

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

EPA Cooling Water Intake Rules (Section 316(b))
Section 316(b) of the CWA requires that the cooling water intake structures at electric power plants meet 
best available technology standards so that mortality from entrainment (drawing aquatic life into a plant's 
cooling system) and impingement (trapping aquatic life on screens) are reduced. Section 316(b) is 
implemented in Wisconsin through modifications to plants' WPDES permits in a timeframe determined by 
the rule. Although new facilities have been required to meet 316(b) standards for some time, regulations for 
existing facilities have not yet been finalized but are expected to be issued by EPA in 2014.  

The currently proposed rule for existing plants allows for a state permitting agency's discretion in 
determining best technology available at plants and does not require cooling towers in all instances. Blount 
and Columbia generating plants are subject to both the impingement and entrainment aspects of the current 
proposed rule. WCCF is subject to the impingement aspect only. The Elm Road Units met the new facility 
requirements when it was built. We anticipate that under the current proposed rule, equipment would need to 
be installed at Blount, WCCF and Columbia to meet the new standards. However it is not presently possible 
to estimate the potential costs associated with this rule because the rule has not been finalized. 

90 

 
EPA's Proposed Effluent Limitations Guidelines and Standards for Steam Electric Power Generating Point 
Source Category
In June 2013, the EPA published a proposed rule focusing on the reduction of metals and other pollutants in 
wastewater from new and existing electric generation plants with a focus on coal-burning plants. The 
proposed rule regulates wastewater from seven specific wastewater types. The proposed rule is technology-
driven in that specific technologies may need to be installed to meet the rule's requirements. Sites that 
already have these technologies will be deemed to meet the requirements of the rule. The proposed rule as 
written will likely affect wastewater systems at Columbia and the Elm Road Units. 

The EPA has signed a consent decree to finalize the rule by May 2014 and have the rule apply to power 
plants as they renew their water discharge permits beginning in July 2017. Based on our current evaluation 
of the proposed rule and its alternatives we may need to add treatments systems or additional equipment at 
our Elm Road and Columbia facilities. We will have a better understanding of potential costs to MGE once 
the rule is finalized. 

Energy Efficiency and Renewables

The Wisconsin Energy Efficiency and Renewables Act requires that, by 2015, 10% of the state's electricity 
be generated from renewable resources. MGE is in compliance with the 2015 requirement. The costs to 
comply with the Act and its accompanying regulations are being recovered in 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 
interstate pollution transport rules, maximum achievable control technology (MACT) standards, such as the 
Reciprocating Internal Combustion Engine (RICE) MACT, new source performance standards (NSPS), the 
Clean Air Visibility Rule (also known as the Regional Haze Rule), and mercury emissions limits are 
expected to result in additional operating and capital expenditure costs for electric generating units. 

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

In 2000, the U.S. Court of Appeals for the D.C. Circuit held that Wisconsin had been illegally included in a 
portion of the NOx SIP Call, but stayed the remaining legal challenges to the rule pending EPA's 
development of additional interstate pollution transport rules. The EPA developed the CAIR to replace the 
NOx SIP Call, but in 2008, the U.S. Court of Appeals for the D.C. Circuit remanded the CAIR to the EPA 
with directions to revise or replace the rule. In 2011, the EPA developed CSAPR which the U.S. Court of 
Appeals for the D.C. Circuit vacated in 2012 with directions that the EPA temporarily reinstate CAIR. That 
decision was argued before the U.S. Supreme Court in December 2013, and a decision is pending. The CAIR 
remains effective. 

The CAIR generally requires NOx and SO2 emission reductions from fossil fuel-fired EGUs (25 MW or 
greater) in the eastern half of the United States in two phases and includes a regional cap-and-trade system. 
Phase I is currently in place. Phase II begins in 2015 and will require regional NOx and SO2 emissions 
reductions from 2003 levels by 65% and 70%, respectively. MGE owns or has partial ownership in several 
generation units currently subject to the CAIR: Blount, Columbia, Elm Road Units, and its combustion 
turbines located in West Marinette and Fitchburg.  

Based on our evaluation of Phase II of CAIR, we will be able to meet NOx emissions reductions through 
using our NOx allowances provided through the rule, and we will meet SO2 emissions reductions through 
installation of pollution controls. New SO2 controls that will meet or exceed CAIR allowances at Columbia 
are underway and are planned to be completed by mid-2014 (see the discussion regarding the Columbia 
environmental project below). MGE expects that any costs incurred to meet Phase II of the CAIR will be 
fully recoverable through rates. We will continue to monitor the Supreme Court's response to the CSAPR 
appeals and any actions by the EPA on any new or revised interstate transport rule.  

91 

 
Clean Air Visibility Rule (CAVR)
Air modeling indicates that SO2 and NOx emissions (and to a lesser extent particulate matter) from Columbia 
may impair visibility at certain Class I Scenic Areas. Columbia may therefore be subject to the best available 
retrofit technology (BART) regulations, a subsection of the EPA's Clean Air Visibility Rule (CAVR), which 
may require pollution retrofits. The EPA had proposed that Columbia's compliance with emissions 
limitations in the CAIR and the CSAPR could also serve as compliance with the BART for SO2 and NOx
emissions. However, this proposal is now uncertain because of the D.C. Circuit remanding the CAIR to the 
EPA and vacating the CSAPR. The Sierra Club has sought federal appellate court review of Wisconsin's 
implementation plan for the BART portion of CAVR and that appeal has been stayed pending the U.S. 
Supreme Court's decision on CSAPR. At this time, the BART regulatory obligations, compliance strategies 
and costs remain uncertain. 

Reciprocating Internal Combustion Engines Maximum Achievable Control Technology (RICE MACT)
In January 2013, the EPA finalized amendments to its RICE MACT standard. RICE MACT applies to 
industrial or electrical engines that are classified as reciprocating internal combustion engines. Engines 
owned by MGE that would fall under the RICE MACT rule include backup generators and small engines at 
various locations, including our fleet of distributed generators that serve as electric system backup and 
emergency dispatch. Our units that currently serve as system or emergency backup will be restricted to 
emergency operation and limited (50 hours) non-emergency operation annually or will require additional 
pollution control equipment to run more often. The EPA issued a notice of reconsideration in August 2013 
on the 50 hour non-emergency operating limit. MGE is currently installing pollution control equipment on a 
number of units. MGE will continue to monitor developments regarding potential changes to the number of 
hours allowed for non-emergency operation. 

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

GHG New Source Performance Standards (NSPS) for New and Existing Electric Generating Units
In a June 2013 directive, President Obama instructed the EPA to re-propose greenhouse gas standards for 
new power plants, based on comments received on their original rule proposal issued in March 2012, and to 
finalize those standards in a timely manner. The EPA developed proposed standards for new power plants in 
September 2013, which would require, if finalized, that new coal-fired units and small natural gas units meet 
carbon dioxide emission levels significantly below current levels. 

The June 2013 directive also instructed the EPA to propose standards, regulations or guidelines for modified, 
reconstructed and existing power plants under Sections 111(b) and 111(d) of the Clean Air Act no later than 
June 2014 and to finalize those standards by June 2015. The directive further instructs the EPA to require 
states to submit implementation plans for this rule by June 30, 2016. It is reasonable to assume that costs of 
implementation of this rule could be significant depending on the approach taken. We will continue to 
monitor this rule in 2014. 

National Ambient Air Quality Standards (NAAQS)
The EPA has announced that they will be reviewing all of their NAAQS in 2014. Changes in NAAQS can 
affect the determination as to whether an area is designated as nonattainment, which can affect permitting, 
capital expenditures and operating costs for emission sources in those nonattainment areas. MGE will be 
monitoring the outcome of this planned review to evaluate whether changes affect our operations. MGE 
continues to monitor NAAQS closely because our generation facilities in areas designated as nonattainment 
for a NAAQS may have additional permitting requirements, including compliance demonstrations and/or 
equipment installations.  

In addition the EPA has developed draft SO2 NAAQS technical documents as guidance to states for 
classifying areas as attainment or nonattainment. The documents provide guidance for monitoring and/or 
modeling to determine SO2 levels. We are currently unable to assess operational or capital costs associated 
with adoption of the final guidance as it has not been adopted by the State of Wisconsin. We will be 
monitoring State of Wisconsin actions to better evaluate the effect it may have on our Columbia and the Elm 
Road Units. 

92 

 
Columbia

Based upon current available information, compliance with various environmental requirements and 
initiatives is expected to result in significant additional operating and capital expenditures at Columbia as 
noted below.  

Columbia Environmental Project
In early 2011, the PSCW issued a Certificate and Order authorizing the construction of scrubbers and bag 
houses and associated equipment on Columbia Units 1 and 2 to reduce SO2 and mercury emissions. The 
scrubbers and bag houses are expected to support compliance obligations for current and anticipated air 
quality regulations, including CAIR, CAIR's eventual replacement, the Mercury and Air Toxics Standards 
(MATs) and the Wisconsin Mercury Rule. WPL, the plant operator, currently estimates that MGE's share of 
the capital expenditures required for this project is approximately $135 million. The project is underway and 
estimated to be completed in mid-2014. 

MGE's share of various contractual commitments entered for the project as of December 31, 2013, is 
$14.7 million. These costs are expected to be capitalized and included in the consolidated balance sheets of 
MGE Energy and MGE. See Footnote 20 for further information regarding the Columbia environmental 
construction project. 

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, as owner-operator, and the other co-owners failed to comply with appropriate 
pre-construction review and permitting requirements and, as a result, violated the PSD program 
requirements, the Title V operating permit requirements of the CAA and the Wisconsin State 
Implementation Plan (SIP). In April 2013, the EPA filed a lawsuit against the co-owners of Columbia 
asserting similar allegations. In September 2010 and April 2013, Sierra Club filed lawsuits against WPL 
alleging violations of the CAA at Columbia and other WPL-operated Wisconsin facilities.  

In April 2013, WPL, as owner-operator, along with the other owners of Columbia, entered into a consent 
decree with the EPA and the Sierra Club to resolve these claims, while admitting no liability. In June 2013, 
the consent decree was approved and entered by the Court. The consent decree requires installation of the 
following emission controls at Columbia: scrubbers and baghouses at Columbia Units 1 and 2 by 
December 31, 2014, and an SCR system at Columbia Unit 2 by December 31, 2018. In addition, the consent 
decree establishes emission rate limits for SO2, NOx, and particulate matter for Columbia Units 1 and 2. The 
consent decree also includes annual plant-wide emission caps for SO2 and NOx for Columbia. MGE also 
paid approximately $0.2 million as its share of a civil penalty and will complete approximately $0.6 million 
in environmental mitigation projects. MGE intends to seek recovery in rates of the costs associated with its 
compliance with the terms of the final consent decree and currently expects to recover any material 
compliance costs.  

e.  Legal Matters - MGE Energy and MGE.

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

f.  Elm Road - MGE Energy and MGE.

The warranty periods for both of the Elm Road Units have expired. During 2013, WEPCO and Bechtel (the 
construction contractor for the Elm Road Units) were working through the outstanding warranty claims. The 
warranty claim for the costs incurred to repair steam turbine corrosion damage identified on both units was 
resolved through a binding arbitration in June 2013. Final acceptance of the Elm Road Units occurred in 
June 2013 after all requirements stated in the contract with Bechtel were satisfied. 

g.  Other Commitments.

MGE Energy holds investments in nonpublic entities. From time to time, these entities require additional 
capital infusions from their investors. MGE Energy has committed to contribute $1.7 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. 

93 

 
In addition, MGE Energy has a three year agreement with a venture debt fund expiring in December 2016. 
MGE Energy has committed to invest up to a total of $1.0 million into this fund. As of December 31, 2013, 
MGE Energy has $0.5 million remaining in commitments. The timing of infusions is dependent on the needs 
of the fund and is therefore uncertain at this time. 

MGE has several other commitments related to various projects. Payments for these commitments are 
expected to be as follows:

19.  Asset Retirement Obligations - MGE Energy and MGE.

MGE recorded an obligation for the fair value of its legal liability for asset retirement obligations (AROs) 
associated with removal of the West Campus Cogeneration Facility and the Elm Road generating units, electric 
substations, combustion turbine generating units, wind generating facilities, and photovoltaic generating 
facilities, all of which are located on property not owned by MGE Energy and MGE and would need to be 
removed upon the ultimate end of the associated leases. The significant conditional AROs identified by MGE 
included the costs of abandoning in place gas services and mains, the abatement and disposal of equipment and 
buildings contaminated with asbestos and PCBs, and the proper disposal and removal of tanks, batteries, and 
underground cable. Changes in management's assumptions regarding settlement dates, settlement methods, or 
assigned probabilities could have a material effect on the liabilities recorded by MGE at December 31, 2013, as 
well as the regulatory asset recorded. 

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

The following table shows a rollforward of the AROs from January 1, 2012, to December 31, 2013. Amounts 
include conditional AROs.

In 2012, MGE recorded a decrease in revisions in estimated cash flows of $1.3 million based on revised 
asbestos abatement estimates.  

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

MGE and two other utilities jointly own Columbia, a coal-fired generating facility. WPL is the plant operator and 
permit holder, and owns 46.2% of Columbia. WPSC owns a 31.8% interest and MGE owns a 22% interest in 
Columbia. In early 2011, the PSCW issued a Certificate and Order authorizing the construction of scrubbers and 
bag houses and associated equipment on Columbia Units 1 and 2 to reduce SO2 and mercury emissions. The 
scrubbers and bag houses are expected to support compliance obligations for current and anticipated air quality 
regulations, including CAIR, CAIR's eventual replacement, MATS and the Wisconsin Mercury Rule. The 
operator's current estimate shows that MGE's share of the capital expenditures required for this project is 
approximately $135 million. As of December 31, 2013, MGE had accumulated $120.9 million (excluding 
carrying costs) related to its share of the project, which is reflected in the Construction Work in Progress balance 
on MGE Energy's and MGE's consolidated balance sheets. MGE expects to incur capital expenditures of 
$14 million in 2014. This amount may change as a result of modifications to the project estimate or timing 
differences. MGE has recognized $2.7 million and $1.4 million (after tax) in AFUDC equity related to this 
project for the years ended December 31, 2013 and 2012, respectively. 

94 

 
MGE expects that the costs pertaining to this project will be fully recoverable through rates. For 2012, the PSCW 
authorized MGE 100% AFUDC on this project during construction. Beginning in 2013, similar to MGE's other 
utility construction projects, the PSCW authorized MGE a 50% current return (included in customer rates) and 
the remaining 50% as AFUDC. For 2014, the PSCW authorized MGE 100% AFUDC on this project during 
construction.  

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

MGE.

a.  Presentation of Comprehensive Income.

In February 2013, the FASB issued authoritative guidance within the Codification's Comprehensive Income 
topic that provides guidance on the reporting of amounts reclassified out of accumulated other 
comprehensive income. Reclassification adjustments will be presented either on the financial statement 
where income is presented or as a separate disclosure in the notes to the financial statements. This 
authoritative guidance became effective January 1, 2013. The authoritative guidance had no effect on our 
financial statement presentation or notes to the financial statements. 

b.  Disclosures about Offsetting Assets and Liabilities.

In December 2011, the FASB issued authoritative guidance within the Codification's Balance Sheet topic 
that provides guidance on disclosures about offsetting assets and liabilities. The new disclosure requirements 
mandate that entities disclose both gross and net information for instruments and transactions eligible for 
offset in the balance sheet as well as instruments and transactions subject to a master netting arrangement. In 
addition, the standard requires disclosure of collateral received and posted in connections with a master 
netting arrangement. On January 31, 2013, the FASB issued additional authoritative guidance which 
clarified the scope of disclosures about offsetting assets and liabilities. The revised guidance limits the scope 
of the new balance sheet offsetting disclosures to derivatives, repurchase agreements, and securities lending 
transactions to the extent that they are (1) offset in the financial statements or (2) subject to an enforceable 
master netting arrangement or similar agreement. This authoritative guidance became effective January 1, 
2013. The authoritative guidance did not have a financial impact, but required additional disclosures. See 
Footnote 16 for additional information. 

c.  Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of 

the Obligation Is Fixed at the Reporting Date.

In February 2013, the FASB issued authoritative guidance within the Codification's Balance Sheet topic that 
provides guidance on the recognition, measurement, and disclosure of obligations resulting from joint and 
several liability arrangements for which the total amount of the obligation is fixed at the reporting date. This 
authoritative guidance became effective January 1, 2014. The authoritative guidance will not have a financial 
or disclosure impact. 

d.  Presentation of an Unrecognized Tax Benefit.

In July 2013, the FASB issued authoritative guidance within the Codification's Income Statement topic that 
provides guidance on the presentation of an unrecognized tax benefit when a net operating loss carryforward, 
a similar tax loss, or a tax credit carryforward exist. The authoritative guidance was issued to eliminate 
diversity in practice by providing guidance on the presentation of unrecognized tax benefits. This 
authoritative guidance became effective January 1, 2014. The authoritative guidance will not have a financial 
statement or disclosure impact, unless MGE Energy or its subsidiaries are in a net operating loss position. 
We do not expect to be in a net operating loss position in 2014.  

22. 

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. 

95 

 
The nonregulated energy operations are conducted through MGE Energy's subsidiaries: MGE Power, MGE 
Power Elm Road, and MGE Power West Campus. These subsidiaries own and lease electric generating capacity 
to assist MGE. MGE Power Elm Road has an ownership interest in two coal-fired generating units in Oak Creek, 
Wisconsin, which are leased to MGE, and MGE Power West Campus owns a controlling interest in the electric  

generation plant of a natural gas-fired cogeneration facility on the UW campus. MGE Power West Campus's 
portion is also leased to MGE. 

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

The "All Others" segment includes: corporate, CWDC, MAGAEL, MGE Construct, NGV Fueling Services, and 
North Mendota. These entities' operations consist of investing in companies and property which relate to the 
regulated operations, financing the regulated operations, or owning and operating natural gas compression 
equipment. 

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

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

Notes:

(cid:120)

(cid:120)

The quarterly results of operations within a year may not be comparable because of seasonal and other factors. 

The sum of earnings per share of common stock for any four quarters may vary slightly from the earnings per 
share of common stock for the equivalent twelve-month period due to rounding. 

(cid:120) MGE Energy's operations are based primarily on its utility subsidiary MGE. 

(cid:120)

Per share amounts for all periods presented reflect the three-for-two stock split declared on December 20, 
2013, effective in the form of a stock dividend distributed on February 7, 2014. 

24.  Related Party Transactions - MGE Energy and MGE.

Item 9A. Controls and Procedures.

MGE Energy and MGE

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

During the fourth quarter of 2013, each registrant's management, including the principal executive officer and principal 
financial officer, evaluated its disclosure controls and procedures related to the recording, processing, summarization, 
and reporting of information in its periodic reports that it files with the SEC. These disclosure controls and procedures 
have been designed to ensure that material information relating to that registrant, including its subsidiaries, is 
accumulated and made known to that registrant's management, including its principal executive officer and its principal 
financial officer, by other employees of that registrant and its subsidiaries as appropriate to allow timely decisions 
regarding required disclosure, and that this information is recorded, processed, summarized, evaluated, and reported, as 
applicable, within the time periods specified in the SEC's rules and forms. Due to the inherent limitations of control 
systems, not all misstatements may be detected. These inherent limitations include the realities that judgments in 
decision making can be faulty and breakdowns can occur because of simple error or mistake. Additionally, controls can 
be circumvented by the individual acts of some persons, by collusion of two or more people, or by management 
override of the control. Also, the registrants do not control or manage certain of their unconsolidated entities, and thus, 
their access and ability to apply their procedures to those entities is more limited than is the case for their consolidated 
subsidiaries. 

As of December 31, 2013, the principal executive officer and principal financial officer of each registrant concluded 
that such registrant's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the 
Securities Exchange Act of 1934) were effective to accomplish their objectives. Each registrant intends to strive 
continually to improve its disclosure controls and procedures to enhance the quality of its financial reporting. 

During the quarter ended December 31, 2013, there were no changes in MGE Energy or MGE's internal controls over 
financial reporting that materially affected, or are reasonably likely to affect materially, MGE Energy or MGE's internal 
control over financial reporting. 

MGE Energy and MGE

Management of MGE Energy and MGE are required to assess and report on the effectiveness of its internal control over 
financial reporting as of December 31, 2013. As a result of that assessment, management determined that there were no 
material weaknesses as of December 31, 2013 and, therefore, concluded that MGE Energy and MGE's internal control 
over financial reporting was effective. Management's Report on Internal Control Over Financial Reporting is included 
in Item 8. - Financial Statements and Supplementary Data.

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

Dividend Restrictions
Dividend payments by MGE to MGE Energy are subject to restrictions arising under a PSCW rate order and, to a 
lesser degree, MGE's first mortgage bonds. The PSCW order restricts any dividends that MGE may pay 
MGE Energy if its common equity ratio, calculated in the manner used in the rate proceeding, is less than 55%. 
MGE's thirteen month rolling average common equity ratio at December 31, 2013, is 57.6% as determined under 
the calculation used in the rate proceeding. MGE paid cash dividends of $25.0 million to MGE Energy in 2013. 
The rate proceeding calculation includes as indebtedness imputed amounts for MGE's outstanding purchase 
power capacity payments and other PSCW adjustments, but does not include the indebtedness associated with 
MGE Power Elm Road or MGE Power West Campus, which are consolidated into MGE's financial statements 
but are not direct obligations of MGE.  

MGE has covenanted with the holders of its first mortgage bonds not to declare or pay any dividend or make any 
other distribution on or purchase any shares of its common stock unless, after giving effect thereto, the aggregate 
amount of all such dividends and distributions and all amounts applied to such purchases, after December 31, 
1945, shall not exceed the earned surplus (retained earnings) accumulated subsequent to December 31, 1945. As 
of December 31, 2013, approximately $305.6 million was available for the payment of dividends under this 
covenant. 

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

Stock Split
On December 20, 2013, MGE Energy's Board of Directors declared a three-for-two stock split of MGE Energy's 
common stock in the form of a stock dividend. The additional shares were distributed February 7, 2014 to all 
shareholders of record as of January 24, 2014. All share and per share data provided in this report give effect to 
this stock split.
