To our shareholders

“ We are embracing  
the opportunities of an 
evolving energy world to 
produce long-term value 
for our shareholders.”

              —  Gary J. Wolter,  

MGE Energy Chairman

Gary J. Wolter, MGE Energy Chairman, with new MGE President and CEO, Jeffrey M. Keebler

We are partnering to create  
a stronger tomorrow. 

Madison Gas and Electric (MGE) partners with our 

customers and our communities to provide critical services, 

to create more sustainable communities and to foster a 

vibrant local economy. These partnerships will continue 

to guide our commitment to reliability, sustainability and 

shareholder value. 

We are proud to be a local company for more than 150 

years. MGE is building upon its rich history as a community 

and industry leader to succeed in a rapidly changing energy 

world. By working together, we can accomplish our goals.

Consistent financial performance 
Building shareholder loyalty is part of our mission. In 
2016, MGE Energy continued to deliver solid financial 
performance for our shareholders in both stock price 
appreciation and dividend increases. 

MGE Energy is among a select group of U.S. companies 
dedicated to investor dividends. Compared to combination 
utility holding companies nationwide, MGE Energy is one of 
only four to increase its dividend for 41 or more consecutive 
years. No other Wisconsin utility or utility holding company 
can match our history of dividend increases. 

Your Board of Directors increased the dividend by 4.2% 
to $1.21 paid per share in 2016. The financial publisher 
Mergent consistently ranks us as a “Dividend Achiever”  
for our annual dividend increases.

2

MGE Energy shareholders also saw an increase in the 
stock price in 2016—building on a long-term trend. In 
the last decade, our stock price has more than doubled, 
outperforming both the Dow Jones Industrial Average  
and the S&P 500.

Strong total return
Stock price appreciation is one part of shareholders’ total 
return, which combines both stock price and reinvested 
dividends. Many shareholders choose to reinvest their 
dividends to grow their investment. 

Taking a five-year view of our annual total return, a $1,000 
investment at the end of 2011 grew to $2,414 by the close 
of 2016 with reinvested dividends. 

Earnings
In 2016, we reported earnings of $2.18 per share, compared 
to $2.06 per share in 2015, resulting from increased electric 
consumption due to a warmer summer in 2016 versus 2015 
and due to an increase in the number of electric and gas 
residential customers. 

Capital expenditures
Our investments have been driven by our high standards 
for energy reliability, by new technologies and by our goals 
for a more sustainable energy future. Under our long-range 
Energy 2030 framework, we project an increase in our 
capital expenditures. 

These projected investments include emission control 
technologies, electric distribution and metering 
expenditures and continued customer additions in MGE’s 
gas service area. We also anticipate increased expenditures 
on renewable energy resources and natural gas generation. 

In addition, we expect to invest a significant amount of 
capital in information technology infrastructure for a more 
dynamic, integrated electric grid. Also, investments in a 
new customer information system, smart meters and other 
systems will help enhance the grid and provide customers 
more information about their energy use.

National recognition
MGE Energy continues to earn recognition nationwide for 
its prudent approach to financial management. MGE, the 
main regulated subsidiary of MGE Energy, maintains the 
highest credit rating of any combination utility in the nation 
from both Standard and Poor’s (S&P) and Moody’s. 

Value Line, Inc., also gives MGE Energy top ratings 
for financial strength and investment safety. We have 
maintained these top ratings for more than a decade.

National recognition from these leading organizations 
reflects our commitment to our shareholders and to 
strategic investments for MGE’s long-term growth.

To our shareholders

Energy 2030: partnering for our future
Through unparalleled engagement with our customers, 
communities, other stakeholders and industry experts, MGE 
is advancing Energy 2030, our ambitious framework for 
our future. Energy 2030 continues our long-term direction 
of reducing carbon emissions, greater use of renewables, 
innovative products and services and ongoing partnerships. 

By listening to and working with our customers, we are 
developing programs, products and services responsive to 
their needs. As we invest in new technologies, we also are 
building shareholder value in a changing energy world. 

Our Energy 2030 framework includes two high-level goals: 

•  To transition toward supplying 30% of retail electric sales 
with renewable resources by 2030; and, 25% of retail 
electric sales with renewable resources by 2025. 

•  To work with customers to reduce carbon dioxide 

emissions by 40% from 2005 levels by 2030. 

In 2016, as part of our ongoing commitment to invest 
further in cleaner energy, MGE reached an agreement to 
reduce our ownership in the Columbia Energy Center near 
Portage, Wis. MGE is a minority owner in the coal-fired 
power plant. Once finalized, this agreement reduces MGE’s 
capacity from Columbia by about 33 megawatts (MW). 

Renewable energy investments 
Under Energy 2030, we also are building on our history of 
renewable energy investments. 

•  MGE is proposing to construct, own and operate its 

largest wind farm to date. MGE began site selection in 
2015 for this 66-MW wind farm about 200 miles west of 
Madison near Saratoga, Iowa. MGE secured the rights to 
the construction-ready site in 2016 from the site’s initial 
developer. The site is well situated due to its strong winds 
and proximity to transmission infrastructure. In February 
2017, MGE filed with state regulators its intent to seek 
approval to build the wind farm. If it receives regulatory 
approval, construction on the approximately $107 million 
project could begin in 2018.

MGE’s Shared Solar installation is on top of the City of 
Middleton’s new operations center. The roof is larger than a  
football field and now holds more than 1,700 photovoltaic  
panels that feed electricity to the grid. 

•  We also completed construction of MGE’s Shared Solar 
pilot project in the City of Middleton on the roof of the 
Municipal Operations Center. MGE owns and maintains 
the 500-kilowatt (kW) solar installation, which delivers 
locally generated solar power to the electric grid. Our 
innovative model for community-sourced solar is one 
example of how we’re partnering to grow investments  
in renewable energy.

Innovation
Innovative products offer new opportunities to partner 
with customers. Our Smart Thermostat Demand Response 
pilot program for residential customers will explore the 
use of smart technology to manage peak power demands. 
With customers’ consent, MGE will be able to use smart 
thermostats to manage the electricity use of residential air 
conditioners to reduce peak in the summer. 

In 2016, MGE launched Charge@Home. This electric 
vehicle charging pilot program offers drivers a faster way 
to charge at their homes. MGE installs and maintains the 
chargers. Customers enjoy faster, more convenient charging 
that can be controlled remotely with a smartphone. Such 
opportunities to work together with customers allow MGE 
to research new technologies while learning more about 
how electric vehicle charging impacts the grid.

Sustainability
MGE partners to help create healthier communities for 
generations to come. As part of our partnership with the 
City of Middleton to build the Shared Solar project, MGE 
also installed a 100-kW solar array on the roof of the city’s 
police department. The electricity from this array helps to 
fulfill the city’s sustainability goal of 25% renewable energy 
by 2025. 

In addition, MGE is collaborating with the City of Madison, 
which also has sustainability goals. MGE and the city 
continue to discuss how to move forward areas of mutual 
interest, including solar, electric vehicles and efficiency. 

MGE’s commitment to sustainable practices extends 
throughout our daily operations. For the third consecutive 
year, MGE has received the Green Master designation from 
the Wisconsin Sustainable Business Council. The statewide 
program evaluates applicants on their sustainable practices 
and results in nine operational areas to be considered for 
the designation. The top 20% of the companies achieve  
the highest-ranking category as a Green Master.

Reliability
Our obligation to provide safe, reliable energy remains a top 
priority. We invest in new technologies, in infrastructure and 
in our people to ensure that MGE is an industry leader in 
electric service reliability. In 2015, we were ranked 

number one in a nationwide industry survey for the fewest 
number of outages. In this yearly survey of more than 90 
electric utilities, MGE has ranked in the top four utilities in 
the country for both the fewest number of outages and the 
shortest duration of outages in each of the last nine years. 

MGE also scores at the top when called upon to respond to 
natural gas leaks. Our crews recorded the second-fastest 
average response times, according to a 2015 nationwide 
survey of more than 80 utilities. MGE averaged a response 
time of 16 minutes compared to a national average of  
26 minutes. 

We continue to expand our natural gas service to more 
customers through our gas expansion model, or GEM, 
program. Since the program’s pilot in 2012, MGE has 
completed 14 GEM projects totaling 182 miles of gas main 
with additional projects planned for 2017. Through our 
GEM program, we’re able to work with new customers and 
grow our investment in safe, dependable natural gas service. 

Continuity for the future
On March 1, 2017, Jeffrey Keebler succeeded Gary Wolter 
as President and CEO. Gary continues to serve the company 
as Chairman. Jeff also has been appointed to our Board 
of Directors. Since joining MGE in 1995, Jeff has served 
in various executive positions including Energy Supply 
and Planning, Customer Services, Information Technology 
and Human Resources. All of our talented employees will 
continue to serve with vision, ingenuity and a commitment 
to being a strong community energy company, building both 
customer and shareholder value. 

We wish to thank our employees, our customers and you, 
our shareholders, for your contributions to our success. 
With deep pride and gratitude, we look forward to the 
future of MGE Energy.

Partnering
for sustainability

A more sustainable future is at the heart 
of our Energy 2030 framework, which 
sets goals for increasing investments 
in renewable energy and for reducing 
carbon emissions by 40% from 2005 
levels by 2030. Working with customers 
and stakeholders, we can reach those 
goals. MGE is offering innovative 
programs and services, encouraging 
energy efficiency and taking advantage 
of new technologies. In a changing 
energy world, we are finding ways to add 
value for our stakeholders—investors, 
customers and communities.

Partnerships lead to new, large  
solar installation

MGE owns and operates a new 1,728-panel solar 
installation built with community support and collaboration. 
Our Shared Solar project is on the roof of the City of 
Middleton’s new operations center. Customers have signed 
up to purchase this clean energy through an innovative 
new program for community solar. Working together, we 
are increasing our investment in renewable resources as we 
advance Energy 2030 and give customers new options to 
support clean energy.

Partnering with Middleton made our Shared Solar project a 
reality. Meeting during the solar construction on top of the 
Middleton Operations Center are (left to right) MGE Assistant 
Vice President Don Peterson, MGE Finance Director Scott 
Schmitt, Middleton Director of Community Development 
Abby Attoun and Middleton City Administrator Mike Davis.

New wind farm proposal advances  
renewable energy goals

Innovative efficiency program  
serves local businesses

MGE is proposing to construct, own and operate a new 
66-megawatt wind farm. This opportunity continues 
the progress the company has made in reducing carbon 
emissions and increasing renewable energy. The project 
represents a long-term, cost-effective strategy for MGE  
to meet its Energy 2030 commitments to cleaner energy. 

MGE secured the rights to the construction-ready site in 
2016 from the site’s initial developer. In February 2017, 
MGE filed with state regulators its intent to seek approval to 
build the wind farm. With regulatory approval, construction 
could begin in 2018. 

The project’s 33 wind turbines would stand nearly 500 feet 
tall. Wind turbine technology has improved with larger 
turbines producing energy more efficiently.

The Saratoga project builds upon MGE’s history of reducing 
carbon emissions and growing renewable resources. Under  
our now completed Energy 2015 framework, MGE increased  
energy from renewable resources by almost 12 times and 
reduced carbon emissions 20% between 2005 and 2015. 

Working with customers to be more energy efficient is  
key to meeting our Energy 2030 goals. 

We are partnering with Wisconsin’s Focus on Energy in 
a pilot program called On Demand Savings. This program 
encourages businesses to better manage their energy use 
when electric use peaks across the region. As part of the 
program, MGE electric meters interface with customers’ 
own energy management systems—providing businesses 
real-time data on their energy use. This allows the businesses 
that participate in On Demand Savings to take action and 
control their energy use during high demand periods and 
helps control costs for all customers in the long run.

MGE is tracking the program’s results as part of its 
partnership with Focus on Energy and the National 
Governors Association. Results from this pilot will be  
shared with the Governors Association, and similar 
programs could be replicated across the country.

The Saratoga wind project is located in northern Iowa, about  
45 miles east of MGE’s Top of Iowa 3 wind farm (pictured 
above). The site is well situated due to its strong winds and  
access to transmission infrastructure. This project would be  
MGE’s largest wind farm to date.

At Spectrum Brands, Facility Engineering Manager Bill Wheeler

about our On Demand Savings pilot program. Spectrum Brands 
effectively used the program to further reduce summertime 
energy demand in its energy-efficient headquarters.

Partnering
for a dynamic, integrated grid

A dynamic, integrated grid accommodates 
two-way electric flow from various 
power sources, such as customer-owned 
solar and biogas installations along with 
traditional power plants. MGE is building 
an advanced grid that can integrate 
new technologies while maintaining our 
national leadership in electric reliability. 

No. 1 in electric reliability in national survey

MGE once again has been recognized as the most reliable 
electric utility in the United States based on the results of a 
national industry survey. In 2016, MGE was ranked number 
one in reliability with the fewest power interruptions based 
on average customer outages in 2015. This reliability is 
core to our service and is the foundation on which we are 
building a utility grid for the future.

We invested in a state-of-the-art distribution management 
system to help us operate, maintain and optimize the  
function of the electric grid. MGE’s Distribution Systems  
Operations Supervisor Ross Hewitt monitors the grid in our  
operations center.

Connecting new energy sources to the grid 

A more advanced electric grid can handle the growth of 
distributed electric generation, such as customer-owned 
solar arrays. MGE works with customers who need help in 
determining how to move forward with solar and also need 
the reliability of grid-connected service. 

Steep & Brew Coffee is a local business with nationwide 
coffee distribution. MGE worked with Steep & Brew to 
connect its 315-panel solar array to our electric grid. 

MGE specialists helped to evaluate the electricity usage 
at the facility and provided insight into customer-owned 
generation. This thriving coffee business uses the electricity 
generated by the solar panels but still needs additional 
energy from MGE. On days when the panels generate 
excess electricity, MGE purchases the excess power and 
feeds it into the grid to help serve all customers. 

Projects like these support our Energy 2030 objective to 
create a more advanced grid that supports and enables  
new technologies.

Ensuring energy reliability for a  
growing economy

MGE plans ahead to meet growing customer needs. A 
building boom in a former factory district along Madison’s 
East Washington Avenue is a prime example. Overall, more 
than $350 million in redevelopment is projected by 2020. 
In addition to high-rise apartments, a new $60 million 
redevelopment project includes a center for entrepreneurs, 
office and commercial space and a 2,500-seat music venue. 

MGE is extending its underground electric network 
system to accommodate this significant, future growth. 
Underground electric network systems are more reliable by 
design. MGE’s system has redundant energy feeds to help 
ensure dependable energy—so if one circuit is out of service, 
the other takes over automatically to keep the power 
flowing without interruption. 

Careful strategic planning and our investment in robust 
infrastructure will provide the energy needed for today  
and tomorrow.

Mark Ballering, owner and founder of Steep & Brew Coffee, 
installed an 80-kilowatt photovoltaic system atop the roof of  
his office, roasting facility and distribution center. 

MGE crews unload a large electric transformer to help power  
a new high-rise development with 244 apartments. Madison’s  
East Washington Avenue is a growing hot spot for high-end  
housing and commercial space.

Partnering
to innovate

MGE partners with customers and 
experts to harness the power of new 
technologies. The way we use energy is 
changing—from plugging in our electric 
vehicles to remotely setting our home 
thermostats. Under our Energy 2030 
framework, we are introducing new 
innovative products and services that 
offer customers more control and value. 
Working with customers, we research 
new technologies to capture benefits  
and provide new value. 

Working together to grow  
the electric vehicle market 

We’re helping customers plug in to make a difference. 
MGE is working to grow the use of electric vehicles in 
our community. We built an extensive network of public 
charging stations. We also offer electric vehicle services, 
such as our workplace charging program for employers. In 
2016, MGE partnered with Nissan and Wisconsin Clean 
Cities on Drive Electric—a successful promotion that 
offered discounted Nissan electric vehicles.

Acumium, a local software development and digital marketing 
company, took advantage of discounted all-electric Nissan 
LEAF® vehicles. Acumium employee Sara Peck, MGE’s 
Debbie Branson and Acumium CEO Dan Costello meet 
at the company’s headquarters. MGE also worked with 
Acumium to implement a workplace charging program.

Project taps smart thermostat technology 

When temperatures climb, demand for electricity goes 
up too. MGE is launching a Smart Thermostat Demand 
Response pilot program to test a new method of controlling 
peaks in energy demand. 

During electric peaks, utilities must use their maximum 
capacity of electric generation, transmission facilities and 
distribution lines. 

Our new pilot program will test using smart thermostats 
to manage residential air conditioners’ operations to 
reduce the demand for electricity while maintaining 
comfort. Smart thermostats can be controlled remotely 
through communication technologies. We are recruiting 
approximately 500 residential customers to participate 
in research with us to better understand the potential for 
reducing electric peaks. 

MGE will, with customers’ permission, use their smart 
thermostats’ communications to set parameters, send 
control signals and report on air conditioner responses.

Solar overhead lighting offers  
a new green option to customers

MGE is expanding its Outdoor Overhead Lighting program 
to include a new solar option. Solar structures gather the 
energy of the sun during the day, store that energy in 
batteries and then illuminate parking lots and other outdoor 
areas at night. 

Customers can choose to have MGE install and maintain 
solar overhead lighting structures—especially for remote 
areas where access to power lines may make outdoor 
lighting cost prohibitive. MGE prepares a customized 
lighting plan and provides fixtures, poles and regular 
maintenance for a low monthly charge. 

Adding the solar option allows MGE to offer customers 
more choices in how they source their energy and could 
potentially lead to new service options. MGE has its own 
outdoor solar lighting projects including a bike path near 
the University of Wisconsin-
Madison campus and a 
local park.

A photovoltaic 
panel captures 
the sun’s 
energy and 
stores it in a 
battery to power 
the overhead light 
at night. MGE will 
offer customers the  
option of installing solar 
outdoor overhead lighting. 

Customers can save energy almost effortlessly with smart  
thermostats. MGE will partner with customers in a pilot program  
that allows us to control their smart thermostats during summer  
energy demand peaks.

Partnering
for a strong community

MGE partners with nonprofits, educators, 
customers, students, businesses, 
municipalities and others to meet the 
needs of the areas we serve. Under 
Energy 2030, we commit to further 
deepen our community engagement.

MGE’s student outreach

Helping the next generation learn  
in and out of the classroom

Educating the next generation is a responsibility we all 
share, which is why MGE partners with local schools and 
academic organizations on a wide range of programs.  
Energy efficiency is a key part of our student outreach, 
which includes an interactive program and energy 
curriculum materials. However, learning doesn’t stop with 
the final school bell. Every day, local nonprofits work with 
children to learn by doing. MGE supports these efforts. For 
example, at Simpson Street Free Press students in grades 
3 through 12 produce and publish news stories on various 
media platforms, participate in book clubs and write book 
reviews to expand their literacy competencies.

WORKING 
WITH OUR 
COMMUNITIES 
TO CREATE A 
BRIGHTER FUTURE

When the school day is over, Simpson Street Free Press begins 
to fill up with students who work on articles that will be 
published in print and online. This 25-year-old nonprofit has 
won dozens of awards for its curriculum and student success. 

Venture fund spurs local business growth 

To help local businesses grow, MGE works with the 
nonprofit Madison Development Corp. MGE and other 
partners formed the Venture Debt Fund, which provides 
loans to high-tech, start-up companies with the potential 
of long-term success and job creation. MGE also supports 
growth in the local technology sector with business 
incubators and by partnering with business, education  
and government leaders. 

Since it began in 2004, the Venture Debt Fund has  
invested in 39 companies in the Madison area. The fund 
allows our economy to reap the dividend of future jobs  
and growing companies. 

TrafficCast is a prime example. This growing company 
monitors traffic across North America, including all cities in 
the U.S. Based on advanced digital traffic data, TrafficCast 
provides travel time forecasting, road speed monitoring  
and route choices. The Venture Debt Fund has provided  
two rounds of financing to TrafficCast as it has continued  
to expand its services and to create jobs.

MGE Foundation partners throughout  
the community

From behind the scenes, the MGE Foundation helps  
support a variety of nonprofit organizations that help  
keep our community strong. In the last five years, the MGE 
Foundation has given more than $4.6 million to more than 
350 community organizations ranging from the Boys and 
Girls Club to the United Way of Dane County. 

We understand the importance of being a true community 
partner—whether it’s through financial donations or giving 
of our time and talent. For example, in 2016, we launched 
our Career Ambassador program so high school students 
could get hands-on learning at MGE. Outside of work, 
many of our employees volunteer their time with local 
nonprofits—ranging from chambers of commerce to Big 
Brothers Big Sisters. Being a good, local partner is part of 
our mission to serve as a community energy company.

TrafficCast’s operations center monitors cities across the 
nation. Meeting are (left to right) Nick Kiernan, TrafficCast 
Executive Vice President of Sales/Business Development; John 
Drury, MGE’s Senior Business Development Manager; and 
Lorrie Heinemann, President of Madison Development Corp.

Karla Thennes, Executive Director of Porchlight, stands in  
front of a new development with 16 efficiency apartments to 
provide people with supportive, permanent housing. The  
MGE Foundation donated to the capital campaign and to  
help Porchlight fulfill its mission to decrease the  
homeless population.

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 17. 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, except as required by law. 

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. Information contained on MGE Energy's and MGE's websites shall not be deemed 
incorporated into, or to be a part of, this report.

MGE Energy operates in the following business segments: 

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

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

  Nonregulated energy operations – owning and leasing electric generating capacity that assists MGE through 

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

  Transmission investments – representing our investment in American Transmission Company LLC, a company 
engaged in the business of providing electric transmission services primarily in Wisconsin, and our investment 
in ATC Holdco, a company created to facilitate out-of-state electric transmission development and investments. 

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

regulated operations, through its wholly owned subsidiaries CWDC, MAGAEL, MGE State Energy Services, 
NGV Fueling Services, 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, 2016, MGE supplied electric service to approximately 149,000 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 87% were residential and 13% were commercial or industrial. Electric retail 
revenues for 2016, 2015, and 2014 were comprised of the following:

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

MGE is registered with North American Electric Reliability Corporation (NERC) and one regional entity, the 
Midwest Reliability Organization (MRO). The essential purposes of these entities are the development and 
implementation of regional and NERC reliability standards; and determining compliance with those standards, 
including enforcement mechanisms. 

Transmission 

American Transmission Company LLC (ATC) was formed by utilities who were required by Wisconsin law to 
contribute their transmission facilities to it in 2001, and is owned by those utilities and their affiliates. 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, is regulated 
by the PSCW as to some aspects of its governance and is a transmission-owning member of the MISO. 

Regional Transmission Organizations (RTO) 

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. Sources used depend on 
market prices, generating unit availability, weather, and customer demand. During 2016, 2015, and 2014, MGE's 
electric energy delivery requirements were satisfied from the following fuel sources:

Generation Sources 
MGE receives electric generation supply from coal-fired, gas-fired, and renewable energy sources. These sources 
include owned facilities as well as facilities leased from affiliates and accounted for under our nonregulated energy 
operations. See Item 2. Properties for more information regarding these generation sources, including location, 
capacity, ownership or lease arrangement, and fuel source. See "Nonregulated Energy Operations" below for more 
information regarding generating capacity leased to MGE by nonregulated subsidiaries. 

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, 2016, with unaffiliated parties for the next five years.

Gas Utility Operations 

MGE transports and distributes natural gas in a service area covering 1,682 square miles in seven south-central 
Wisconsin counties. The service area includes the city of Madison, Wisconsin and surrounding areas. 

At December 31, 2016, MGE supplied natural gas service to approximately 154,000 customers in the cities of Elroy, 
Fitchburg, Lodi, Madison, Middleton, Monona, Prairie du Chien, Verona, and Viroqua; 25 villages; and all or parts 
of 48 townships. Of the total number of customers, approximately 90% were residential and 10% were commercial 
or industrial. Gas revenues for 2016, 2015, and 2014 were comprised of the following:

(a)   During 2015, a large interruptible industrial customer decided to purchase gas from a third party supplier 
       to use MGE's facilities for the transport of that gas, resulting in a shift in gas revenues between industrial 
       and transportation services. 

Gas operations accounted for approximately 24.8%, 25.8%, and 36.0% of MGE's total 2016, 2015, and 2014 
regulated revenues, respectively. 

MGE can curtail gas deliveries to its interruptible customers. Approximately 3% of retail gas deliveries in 2016 and 
2015 were to interruptible customers. 

Gas supply 

MGE has physical interconnections with ANR Pipeline Company (ANR) and Northern Natural Gas Company 
(NNG). MGE's primary service territory, which includes Madison and the surrounding area, receives deliveries at 
one NNG and four ANR gate stations. MGE's outlying territory 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 5,936,318 Dth of gas can be injected into ANR's storage fields in Michigan from April 1 
through October 31. These gas supplies are then available for withdrawal during the subsequent heating season, 
November 1 through March 31. Using storage allows MGE to buy gas supplies during the summer season, when 
prices are normally lower, and withdraw these supplies during the winter season, when prices are typically higher. 
Storage also gives MGE more flexibility in meeting daily load fluctuations.

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

 
 

162,150 Dth (including 106,078 Dth of storage withdrawals) on ANR. 
65,828 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. These sources consist of the Elm Road Units and the WCCF, which are leased by MGE 
Power Elm Road and MGE Power West Campus, respectively, to MGE. See Item 2. Properties for a description of 
these facilities, their joint owners, and the related lease arrangements. 

Transmission Investments 

ATC owns and operates electric transmission facilities primarily in Wisconsin. MGE received an interest in ATC 
when it, like other Wisconsin electric utilities, contributed its electric transmission facilities to ATC as required by 
Wisconsin law. That interest is presently held by MGE Transco, which is owned by MGE Energy. At December 31, 
2016, MGE Transco held a 3.6% ownership interest in ATC. 

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

In 2016, ATC Holdco was formed by several of the members of ATC, including MGE Energy, to facilitate electric 
transmission development and investments outside of Wisconsin. MGE Energy's ownership interest in ATC Holdco 
is held by MGEE Transco, a wholly-owned subsidiary. At December 31, 2016, MGEE Transco held a 4.0% 
ownership interest in ATC Holdco. In the near term, it is expected that ATC Holdco will be pursuing transmission 
development opportunities that typically have long development and investment lead times before becoming 
operational. 

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 air and water standards, and potential 
climate change legislation. 

Water Quality 

EPA's Effluent Limitations Guidelines (ELG) and Standards for Steam Electric Power Generating Point Source 
Category 
The ELG rule establishes federal limits on the amount of metals and other pollutants that can be discharged in 
wastewater from new and existing steam electric generation plants. The ELG rule mostly covers pollutants that are 
captured by certain air pollution control systems and via wet ash handling systems at coal-burning power plants with 
units greater than 50 MW generation capacity. The operators of our Columbia and Elm Road Units have indicated 
that equipment upgrades may be necessary to comply with the new discharge standards. The rule will be applied to 
Wisconsin-based power plants as they renew their WPDES permits, beginning in 2018 but no later than 2023. 
Management believes that any compliance costs will be recovered in future rates based on previous treatment of 
environmental compliance projects. 

EPA Cooling Water Intake Rules (Section 316(b)) 
Section 316(b) of the Clean Water Act requires that the cooling water intake structures at electric power plants meet 
best available technology standards so that mortality from entrainment (drawing aquatic life into a plant's cooling 
system) and impingement (trapping aquatic life on screens) are reduced. The Wisconsin Department of Natural 
Resources is currently developing guidance and rules to implement the EPA 316(b) rule.  

10 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Both our Blount plant and our Columbia plant have WPDES permits that are up for renewal in 2017 and will need to 
comply with the 316(b) requirements, Blount has conducted historical studies that will show that it will likely be in 
compliance with this rule. The operator of our Columbia plant is conducting an intake study to demonstrate 
compliance and/or identify design criteria needed to meet the new rule requirements prior to Columbia's 2017 
WPDES permit renewal. The exact requirements at Blount and Columbia, however, will not be known until the 
WDNR finalizes its rule, approves the plant operators' approach, and WPDES permits are modified to account for 
this rule. Nonetheless, MGE expects that the 316(b) rule will not have material effects on its existing plants. 

Energy Efficiency and Renewables 

The Wisconsin Energy Efficiency and Renewables Act requires that 10% of the state's electricity be generated from 
renewable sources. MGE is in compliance with the requirement. The costs to comply with the Act and its 
accompanying regulations are being recovered in rates. 

Air Quality 

Air quality regulations promulgated by the 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 may result in additional operating and capital expenditure costs 
for fossil-fueled electric generating units. 

Ozone NAAQS 
In October 2015, the EPA revised the primary and secondary ozone NAAQS, lowering it to 70 ppb. The final 
standard will likely cause Milwaukee County, where our Elm Road Units are located, to be designated as 
nonattainment for ozone. A nonattainment designation may have an effect on operations at our facilities, however, 
the NAAQS process involves many steps and any effect on our generation units will not be fully understood until 
the State of Wisconsin develops, receives approval for, and finalizes an implementation plan for any counties found 
to be in nonattainment.  

The State of Wisconsin has joined a lawsuit filed by several states challenging the EPA's new ozone standard. Oral 
arguments in this case are scheduled to begin in April 2017. MGE will continue to monitor the EPA's progress on 
attainment designations and related litigation to assess potential impacts at our facilities, particularly our Elm Road 
Units. 

Nitrogen Dioxide (NO2) NAAQS 
The WDNR has revised its state rules to incorporate the EPA's one hour NO2 NAAQS rule that was finalized in 
2010. The effective date of the state rule was August 1, 2016. The WDNR is currently seeking input from the public 
on ideas for implementing this one-hour standard. Wisconsin's NO2 NAAQS rule will affect our stationary fossil-
fuel generation sources by requiring that we demonstrate consistency with the NAAQS when applying for certain air 
permits. Sources that cannot demonstrate compliance with the NAAQS may be required to install emission controls 
or restrict operations. MGE will continue to monitor developments while the WDNR implements guidance for 
compliance with the one-hour NAAQS. 

EPA's Cross-State Air Pollution Rule: Proposed Ozone Season Update based on 2008 Ozone NAAQS 
The EPA's Cross-State Air Pollution Rule (CSAPR) is an interstate air pollution transport rule designed to reduce 
ozone and fine particulate (PM2.5) air levels in areas that the EPA has determined are being affected by pollution 
from neighboring and upwind states. This is accomplished in the CSAPR through a reduction in SO2 and NOx from 
qualifying fossil-fuel fired power plants in upwind or "contributing" states. NOx and SO2 contribute to fine 
particulate pollution, and NOx contributes to ozone formation. Reductions are achieved through a cap and trade 
system. Individual plants can meet their caps through modifications and/or buying allowances on the market. 

In October 2016, the EPA finalized rulemaking for an update to CSAPR that incorporated 2008 Ozone NAAQS 
levels into the rule (the original CSAPR is based on 1997 Ozone NAAQS levels). The update affects 22 states, 
including Wisconsin, by further limiting statewide NOx allowances in each of those states. The rule also includes 
revisions to CSAPR that are designed to address issues remaining from the D.C. Circuit remand of CSAPR, 
including Wisconsin's inclusion in the NOx ozone season portion of the rule. The State of Wisconsin filed a legal 
challenge to the CSAPR update rule asserting, among other things, that the rule over-controls NOx emissions in 
Wisconsin.  

11 

  
 
 
 
 
 
 
 
 
 
 
 
 
The CSAPR Update rule will further reduce summertime (or Ozone Season) NOx emissions allocations from power 
plants starting in 2017. MGE intends to meet the rule requirements through a combination of allocations owned, 
received, or purchased. Depending on the number of allocations MGE receives for ozone season, the number of 
allocations that MGE must purchase, and the cost of allocations, this requirement could be material for MGE. 

Clean Air Visibility Rule (CAVR) 
Columbia is subject to the best available retrofit technology (BART) regulations, a subsection of the EPA's Clean 
Air Visibility Rule (CAVR), which may require pollution control retrofits. Columbia's existing pollution control 
upgrades, and the EPA's stance that compliance with the CSAPR equals compliance with BART, should mean that 
Columbia will not need to do additional work to meet BART requirements. At this time, however, the BART 
regulatory obligations, compliance strategies, and costs remain uncertain due to the continued legal challenges 
surrounding CSAPR and CAVR. 

In December 2016, the EPA introduced a final rule (posted online but not yet scheduled for publication in the 
Federal Register) extending state implementation plan deadlines by three years from 2018 to 2021 for the next 
implementation phase of the CAVR, which goes beyond BART and may affect utilities. This extension would allow 
for states to coordinate their CAVR compliance with other compliance efforts, which should lessen the burden to 
comply. It is too early to determine if the rule will affect MGE. MGE will continue to monitor developments. 

Global Climate Change 

MGE is a producer of GHG emissions, primarily from the fossil fuel generating facilities it uses 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, operational limits on our coal plants, permitting 
difficulties, and emission limits. MGE management would expect to seek and receive rate recovery of such 
compliance costs, if and when required. MGE continues to monitor proposed climate change legislation and 
regulation. 

MGE has taken steps to address GHG emissions through voluntary actions. In 2005, MGE implemented its Energy 
2015 Plan, which committed to ensuring a balanced, economic energy supply with reduced environmental 
emissions. The Plan emphasized increased renewable energy, energy efficiency, and new cleaner generation – three 
strategies that reduced GHG emissions. Under the Plan and other actions, our CO2 emissions declined from 2005 to 
2015 by approximately 20% even though total system energy increased. In 2015, MGE announced its Energy 2030 
framework that continues steps to reduce CO2 emissions. Subject to regulatory approvals and other conditions, MGE 
aims to increase renewable energy to 25% of retail electric sales by 2025 and to 30% by 2030. Under our Energy 
2030 framework, we will also work to reduce CO2 emissions by 40% from 2005 levels by 2030. 

Climate Change Legislation 

It is not anticipated that U.S. Congress will enact broad GHG reduction legislation in 2017.  

It is not expected that the Wisconsin Legislature will enact broad GHG regulation in 2017.  

Greenhouse Gas Regulation 

EPA's Greenhouse Gas (GHG) Reduction Guidelines under the Clean Air Act 111d Rule 
The EPA's Clean Power Plan (CPP) rule became effective in December 2015, setting guidelines for states to use in 
developing plans to control GHG emissions from existing fossil fuel-fired EGUs and systems. When fully 
implemented in 2030, the Clean Power Plan is projected to reduce GHG emissions from this sector by 32% below 
2005 levels. States are given up to three years to submit a plan or be subject to a federal plan to meet the reduction 
goals, and states are expected to meet interim goals starting in 2022 and the final goals in 2030. Implementation of 
the rule is expected to have a direct impact on coal and natural gas fired generating units, including possible changes 
in dispatch and additional operating costs. 

In October 2015, many states (including Wisconsin) and other litigants filed petitions with the U.S. Court of 
Appeals for the District of Columbia Circuit. On January 26, 2016, several parties filed a request for a stay of the 
CPP with the U.S. Supreme Court; and on February 9, 2016, the U.S. Supreme Court granted that request. The CPP 
may not be implemented until the courts ultimately resolve the underlying legality of the rule, which is expected in 
2017.  

12 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Given the pending legal proceedings the nature and timing of any final requirements is subject to uncertainty. If the 
rule remains substantially in its present form, it is expected to have a material impact on MGE. 

Solid Waste 

EPA's Coal Combustion Residuals Rule 
In December 2014, the EPA finalized its Disposal of Coal Combustion Residuals from Electric Utilities (CCR) rule. 
The rule became effective in October 2015. It provides that coal ash will be regulated as a solid waste, and defines 
what ash use activities would be considered generally exempt beneficial reuse of coal ash. The rule also regulates 
landfills, ash ponds, and other surface impoundments for coal combustion residuals by regulating their design, 
location, monitoring, and operation. This portion of the rule is accomplished in phases to allow for sites with onsite 
storage and/or disposal to evaluate their compliance with the rule's design criteria. Landfills and impoundments that 
cannot meet design criteria will need to close formally within defined timeframes. 

The Columbia and Elm Road Units co-owners and plant operators are working through the phased requirements to 
plan and implement changes necessary at those facilities to meet design criteria. Review of our Elm Road Units has 
indicated that the costs to comply with this rule are not expected to be significant. Columbia's operator has 
developed a preliminary implementation schedule for meeting the various deadlines spelled out in the rule. Costs at 
Columbia will be dependent on what is determined during the evaluation stage. Management believes compliance 
costs will be recovered in future rates based on previous treatment of environmental compliance projects. 

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 Clean Air Act Litigation 
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 the co-owners, including MGE. 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 June 2013, the court approved and 
entered a consent decree entered by the EPA, Sierra Club, and the co-owners of Columbia. One of the requirements 
of the consent decree requires installation of an SCR system at Columbia Unit 2 by December 31, 2018. Installation 
of the SCR has been approved by the PSCW and is currently under construction. MGE's share of the projected cost 
for the SCR system is estimated to be $22-$24 million, with expected completion in 2018. 

Employees 

As of December 31, 2016, MGE had 704 employees. MGE employs 227 employees who are covered by a collective 
bargaining agreement with Local Union 2304 of the International Brotherhood of Electrical Workers and 84 
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, 
2018. 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, 2018.

Item 1A. Risk Factors. 

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

Regulatory Risk 

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

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

We 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 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. 

The following are significant proposed regulations that are expected to impact our operations: 

The EPA's Cross-State Air Pollution Rule (CSAPR) is an interstate air pollution transport rule designed to reduce 
ozone and fine particulate (PM2.5) air levels in areas that the EPA has determined are being affected by pollution 
from neighboring and upwind states. In October 2016, the EPA finalized rulemaking for an update to CSAPR that 
incorporated 2008 Ozone NAAQS levels into the rule (the original CSAPR is based on 1997 Ozone NAAQS levels). 
The update affects 22 states, including Wisconsin, by further limiting statewide NOx allowances in each of those 
states. Depending on the number of allocations MGE receives for ozone season, the number of allocations that MGE 
must purchase, and the cost of allocations, this requirement could be material for MGE. 

In October 2015, the EPA finalized its Clean Power Plan (CPP) rule with an effective date of December 2015, 
setting guidelines and approval criteria for states to use in developing plans to control GHG emissions from existing 
fossil fuel-fired electric generating units (EGUs) and systems. Implementation of the rule is expected to have a 
direct impact on existing coal and natural gas fired generating units, including possible changes in dispatch and 
additional operating costs. Given the pending legal proceedings, the nature and timing of any final requirements is 
subject to uncertainty. If the rule remains substantially in its present form, it is expected to have a material impact on 
MGE. 

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

MGE has price risk exposure with respect to the price of natural gas, electricity, coal, emission credits, and oil. 
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 is required to 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 in a year is determined in the 
following year and is then reflected in future billings to 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 is 
required to defer costs, less any excess revenues, if its actual fuel costs exceed 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.

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, storage, and use technology. 

Our revenues and the timing of the recovery of our costs could be adversely affected by improvements in power 
generation, storage, and use technology.  

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. Improvements in the energy efficiency of 
lighting, appliances, and equipment will also affect energy consumption by customers. 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 whether due to inadequate on-site resources, restricted operating hours, or 
equipment failure. 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.  

Changes in power generation, storage, and use technology could have significant effects on customer behaviors and 
their energy consumption. Customers could engage in individual conservation efforts by voluntarily reducing their 
consumption of electricity through voluntary changes in energy use and through the use of more energy efficient 
lighting, appliances, and equipment. They could also change their consumption of electricity from us through the 
installation of alternative energy sources, such as roof top solar panels and micro turbines for self-supply. Customer 
energy conservation could adversely affect our results of operations by reducing our revenues without necessarily 
changing our operating costs due to our obligation to serve. 

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 obtain an adequate supply of coal could limit our ability to operate our coal-fired facilities.  

The availability of coal and the means to transport coal could: 

  Affect our operating costs due to increased costs associated with lower levels of generation or the need for 

alternate supply or alternate transportation, 

  Limit our ability to generate electricity if we are unable to arrange adequate deliveries of coal, and  

  Result in potentially higher costs for replacement purchased power as well as potential lost market sales 

opportunities. 

A significant portion of our electric generating capacity is dependent on coal. Demand for coal has been impacted by 
prevailing prices for natural gas and may affect mine performance. Consequently, we are exposed to the risk that 
counterparties to these contracts will not be able to fulfill their obligations. Disruption in the delivery of fuel, 
including disruptions as a result of transportation delays, weather, labor relations, force majeure events, or  

16 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
environmental regulations affecting any of these fuel suppliers, could limit our ability to generate electricity at our 
facilities at the desired level. Should counterparties fail to perform, or other unplanned disruptions occur, we may be 
forced to replace the underlying commitment at higher prices, or we may be forced to reduce generation at our coal 
units and replace this lost generation through additional power purchases from third parties. These factors may also 
affect the terms under which any of our existing coal supply or transportation agreements are renewed or replaced 
upon the expiration of their current terms. 

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

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

 

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

Our operations and confidential information are subject to the risk of cyber-attacks. 

Our operations rely on sophisticated information technology systems and networks. Cyber-attacks targeting our 
electronic control systems used at our generating facilities and for electric and gas distribution systems, could result 
in a full or partial disruption of our operations. Any disruption of these operations could result in a loss of service to 
customers and loss of revenue, as well as significant expense to repair system damage and remedy security breaches. 

Our business requires the collection and retention of personally identifiable information of our customers, 
shareholders, and employees, who expect that we will adequately protect such information. A significant theft, loss, 
or fraudulent use of personally identifiable information may cause our business reputation to be adversely impacted 
and could lead to potentially large costs to notify and protect the impacted persons. The occurrence of such an event 
may cause us to become subject to legal claims, fines, or penalties, any of which could adversely impact our results 
of operations.  

The safeguards we have may not always be effective due to the evolving nature of cyber-attacks. We cannot 
guarantee that such protections will be completely successful in the event of a cyber-attack. If the technology 
systems were to fail or be breached by a cyber-attack, and not be recovered in a timely fashion, we may be unable to 
fulfill critical business functions and confidential data could be compromised, adversely impacting our financial 
condition and results of operations. 

17 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We rely on the performance of our information technology systems, the failure of which could have an adverse 
effect on our business and performance. 

We operate in a highly engineered industry that requires the continued operation of sophisticated information 
technology systems and network infrastructure to manage our finances, to operate our control facilities, to provide 
electric and gas service to our customers, and to enable compliance with applicable regulatory requirements. Our 
computer-based systems are vulnerable to interruption or failure due to the age of certain systems, the introduction 
of viruses, malware, security breaches, fire, power loss, system malfunction, network outages and other events, 
which may be beyond our control. System interruptions or failures, whether isolated or more widespread, could 
impact our ability to provide service to our customers, which could have a material adverse effect on our operations 
and financial performance.  

Acts of terrorism could materially and adversely impact our operations and financial condition. 

Facilities for electric generation, transmission, and gas distribution are subject to the risk of being potential targets of 
terrorist threats and activities. A terrorist act at our facilities could result in a disruption of our ability to generate, 
transmit, transport, purchase, or distribute electricity or natural gas. A possible attack would have additional adverse 
effects, including environmental ramifications, increased security and insurance costs, as well as general economic 
volatility or uncertainty within our service territories. The inability to maintain operational continuity and any 
additional costs incurred for repairing our facilities could materially and adversely affect our financial condition and 
results of operations. 

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. 

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, oil, and 
environmental 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.  

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

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

We are exposed to 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.  

18 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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.

Columbia 

MGE and two other utilities jointly own Columbia, a coal-fired generating facility consisting of two 512 MW units, 
which, at December 31, 2016, accounts for 30% of MGE's net summer rated capacity. Power from this facility is 
shared in proportion to each owner's ownership interest. At December 31, 2016, MGE had a 22% ownership interest 
in Columbia. The other owners are WPL, 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 88 days on December 31, 2015, to approximately 65 days on 
December 31, 2016. See "Executive Overview" under Item 7. Management's Discussion and Analysis of Financial 
Condition and Results of Operations, for a discussion of the reduction in MGE's ownership share in Columbia 
commencing January 2017 and continuing through June 2020.

Elm Road Units 

MGE Power Elm Road and two other owners own undivided interests in the Elm Road Units, consisting of two 
615 MW units, which, at December 31, 2016, account for 14% of MGE's net summer rated capacity. Power from 
these units 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 increased from approximately 50 
days on December 31, 2015, to approximately 51 days on December 31, 2016. 

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 a part of the UW's 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 plant is reflected in property, plant, and equipment on MGE Energy's 
and MGE's consolidated balance sheets. 

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

Electric and Gas Distribution Facilities 

At December 31, 2016, MGE owned 872 miles of overhead electric distribution line and 1,236 miles of underground 
electric distribution cable, all of which are located in Wisconsin. These electric distribution facilities are connected 
by approximately 52 substations, installed with a capacity of 1,190,500 kVA. MGE's gas facilities include 2,765 
miles of distribution mains, which are all owned by MGE. 

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, 2016, there were $1.2 million of first mortgage bonds outstanding. See Footnote 9 of the 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 $62.6 million of senior secured notes issued by MGE Power Elm Road. See 
Footnote 9 of the Notes to Consolidated Financial Statements for additional information regarding these senior 
notes.

Item 3. Legal Proceedings. 

MGE Energy and MGE 

MGE Energy and its subsidiaries, including MGE, from time to time are involved in various legal proceedings that 
are handled and defended in the ordinary course of business.

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, above the PSCW authorized 
amount of $43 million, 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, 
2016, is 60.2%, as determined under the calculation used in the rate proceeding. This restriction did not impact

MGE's payment of dividends in 2016. Cash dividends of $50.0 million and $30.0 million were paid by MGE to 
MGE Energy in 2016 and 2015, respectively. In 2016, MGE also transferred its ownership interest in MGE Transco 
to MGE Energy in the form of a dividend in kind of $15.8 million. 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, 2016, approximately $338.5 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 MGE Energy, Inc. Direct Stock Purchase and Dividend Reinvestment Plan (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, 
  Nonregulated energy operations, conducted through MGE Power and its subsidiaries, 
  Transmission investments, representing our equity investment in ATC and ATC Holdco, and  
  All other, which includes corporate operations and services.  

Our principal subsidiary is MGE, which generates and distributes electric energy, distributes natural gas, and 
represents a majority portion of our assets, liabilities, revenues, and expenses. MGE generates and distributes 
electricity to approximately 149,000 customers in Dane County, Wisconsin, including the city of Madison, and 
purchases and distributes natural gas to approximately 154,000 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. MGE will continue to focus on growing earnings while controlling operating and fuel 
costs. MGE maintains safe and efficient operations in addition to providing customer value. We believe it is critical 
to maintain a strong credit standing consistent with financial strength in MGE as well as the parent company in order 
to accomplish these goals. 

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

  Weather, and its impact on customer sales, 
  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, including natural gas prices, 
  Equity price risk pertaining to pension related assets, 
  Credit market conditions, including interest rates and our debt credit rating,  
  Environmental laws and regulations, including adopted and pending environmental rule changes, and 
  Other factors listed in Item 1A. Risk Factors. 

For the year ended December 31, 2016, MGE Energy's earnings were $75.6 million or $2.18 per share compared to 
$71.3 million or $2.06 per share for the same period in the prior year. MGE's earnings for the year ended 
December 31, 2016, were $51.2 million compared to $45.4 million for the same period in the prior year.

Our net income during 2016 compared to 2015 primarily reflects the effects of the following factors: 

  Electric net income increased due to a 5.4% increase in residential electric retail sales as the result of more 

favorable weather conditions in 2016 compared to 2015. Electric utility operations experienced an increase in 
operating and maintenance costs partially offsetting the increase in net income compared to the same period in 
the prior year. 

  Carrying costs incurred during construction of the Elm Road Units and WCCF were recognized by MGE Power 
Elm Road and MGE Power West Campus over the period allowed for recovery in rates. The recovery period 
ended in 2015, contributing to a reduction in nonregulated earnings in 2016. The reduction in earnings was 
partially offset by an increase in lease revenue. 

  Transmission investment income reflects our share of ATC's earnings. ATC's earnings for 2015 reflected a 
charge representing its estimate of its refund liability covering 2015, 2014, and a portion of 2013 associated 
with the return on equity complaint filed with FERC. See "Other Matters" below for additional information 
concerning ATC. 

Our net income during 2015 compared to 2014 primarily reflects the effects of the following factors: 

  Electric net income decreased due to lower AFUDC and higher depreciation expense primarily related to the 
Columbia environmental project being placed in service in April (Unit 2) and July 2014 (Unit 1). In addition, 
there was a 0.3% decrease in electric retail sales in 2015 compared to 2014. 

  Gas net income decreased due to a 27.0% decrease in gas retail sales reflecting lower customer demand 

compared to the demand resulting from the extremely cold weather experienced in 2014. Heating degree days (a 
measure for determining the impact of weather during the heating season) decreased by 18.9% compared to 
2014. The average temperature in January 2015 was 20.1 degrees compared to 11.5 degrees in 2014. 

  ATC's earnings for 2015 reflected a charge representing its estimate of its refund liability covering 2015, 2014, 
and a portion of 2013 associated with the return on equity complaint filed with FERC. See "Other Matters" 
below for additional information concerning ATC. 

  The increase in all other income primarily results from a decrease in voluntary contributions. 

During 2016, the following events occurred: 

2016 Rates: In July 2015, the PSCW approved MGE's request to extend the current accounting treatment for 
transmission related costs through 2016, conditioned upon MGE not filing a base rate case for 2016. This accounting 
treatment allows MGE to reflect any differential between transmission costs reflected in rates and actual costs 
incurred in its next rate case filing. 

2016 Annual Fuel Proceeding: In August 2015, the PSCW approved a $0.00256/kWh fuel credit that began on 
September 1, 2015, and continued throughout 2016. The fuel credit established a mechanism to return $10.9 million 
of fuel savings to electric customers as a bill credit. MGE returned $8.3 million of electric fuel-related savings to 
customers through bill credits during the year ended December 31, 2016. 

In January 2016, the PSCW lowered MGE's 2016 fuel rules monitored costs by $14.8 million as a result of 
continued lower projected fuel costs in 2016. Also, in March 2016, MGE filed its 2015 fuel plan reconciliation 
application showing an overcollection of 2015 fuel rules monitored costs. In July 2016, the PSCW issued a final  

28 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
order stating that MGE shall refund the additional fuel savings incurred during 2015 and 2016 for a total of 
$15.7 million to its retail electric customers over a one-month period. In September 2016, MGE returned 
$15.5 million to customers through bill credits. 

As of December 31, 2016, MGE has deferred $5.6 million of 2016 fuel savings that were in excess of the fuel 
savings included within the fuel credits referenced above. These costs will be subject to the PSCW's annual review 
of 2016 fuel costs, expected to be completed in 2017. 

Loss of Industrial Customer: In November 2015, a large industrial customer announced its intention to relocate its 
operations out of state and to close its manufacturing facilities within our service territory. That closure is expected 
to occur in early 2017. For the years ended December 31, 2016 and 2015, this customer contributed approximately 
$3.4 million and $3.8 million, respectively, of pre-tax earnings. Our rate case filing for 2017 addressed the effects of 
the closure. 

ATC Return on Equity: Several parties have filed complaints with the FERC seeking to reduce the base return on 
equity (ROE) used by MISO transmission owners, including ATC. In June 2016, an administrative law judge issued 
an initial decision regarding a second filed complaint for the period February 2015 through May 2015 that would 
reduce the transmission owners' base ROE to 9.7%. ATC recorded an estimated refund liability with respect to the 
administrative law judge's order, which was reflected within our share of ATC earnings. On September 28, 2016, 
FERC issued an order on the first complaint, for the period November 2013 through February 2015, reducing the 
base ROE to 10.32%. This base ROE also became effective September 28, 2016, and will apply to future periods 
until FERC rules in the second complaint, at which time the base ROE ordered by FERC in the second complaint 
will prospectively become the authorized base ROE. See "Other Matters" below for additional information 
concerning ATC. 

During 2017, several items may affect us, including: 

2017 Rate Case Filing: On December 15, 2016, the PSCW authorized MGE to decrease 2017 rates for retail electric 
customers by 0.8% or $3.3 million and to increase rates for retail gas customers by 1.9% or $3.1 million. The 
decrease in retail electric rates reflects declining fuel and purchased power costs. The increase in retail gas rates 
covers costs associated with MGE's natural gas system infrastructure improvements. The authorized return on 
common stock equity for 2017 is 9.8% on 57.2% common equity. The PSCW also approved MGE's request to 
extend the current accounting treatment for transmission related costs through 2018. 

ATC Return on Equity: Several parties have filed complaints with the FERC seeking to reduce the ROE used by 
MISO transmission owners, including ATC. Any change to ATC's ROE could result in lower equity earnings and 
distributions from ATC in the future. We derived approximately 6.8% and 6.4% of our net income for the years 
ended December 31, 2016 and 2015, respectively, from our investment in ATC. See "Other Matters" below for 
additional information concerning ATC. 

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. At present, it is unclear how the changes in 
the Presidential and EPA administration may affect pending or new legislative or rulemaking proposals or regulatory 
initiatives. Such legislation and rulemaking could significantly affect the costs of owning and operating fossil-fueled 
generating plants, such as Columbia and the Elm Road Units, from which we derive approximately 43% of our 
electric generating capacity as of December 31, 2016. 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, which may lag the 
incurrence of those costs.  

EPA's Clean Power Plan: In October 2015, the EPA finalized its Clean Power Plan (CPP) rule with an effective date 
of December 2015, setting guidelines and approval criteria for states to use in developing plans to control GHG 
emissions from existing fossil fuel-fired electric generating units (EGUs) and systems. Implementation of the rule is 
expected to have a direct impact on existing coal and natural gas fired generating units, including possible changes 
in dispatch and additional operating costs. Given the pending legal proceedings, the nature and timing of any final 
requirements is subject to uncertainty. If the rule remains substantially in its present form, it is expected to have a 
material impact on MGE.

Future Generation: During the first quarter of 2016, MGE entered into an agreement with WPL under which MGE 
may acquire up to 50 MW of capacity in a gas-fired generating plant to be constructed by WPL at its Riverside 
Energy Center in Beloit, Wisconsin, during the five-year period following the in-service date of the plant. The plant 
is expected to be completed by early 2020. MGE and WPL have negotiated an amendment to the existing Columbia 
joint operating agreement, effective January 1, 2017, under which MGE will reduce its obligation to pay certain 
capital expenditures (other than SCR-related expenditures) at Columbia prior to the expected in-service date of the 
Riverside gas-fired generating plant in exchange for a proportional reduction in MGE's ownership in Columbia. On 
January 1 of each year, beginning in 2017 and ending June 1, 2020, the ownership percentage will be adjusted, 
through a partial sale, based on the amount of capital expenditures foregone. During 2016, MGE accrued 
$14.8 million of 2016 capital expenditures that MGE has forgone as part of the ownership transfer agreement with 
WPL. As of December 31, 2016, MGE classified $14.8 million of Columbia assets as held-for-sale on the 
consolidated balance sheets. In January 2017, MGE reduced its ownership interest in Columbia from 22.0% to 
20.4% through the partial sale of plant assets to WPL. By June 2020, MGE's ownership in Columbia is forecasted to 
be approximately 19%. 

Saratoga Wind Farm: On February 21, 2017, MGE filed with the PSCW a letter notifying the commission of MGE's 
intent to seek approval to construct, own and operate a 66MW wind farm, consisting of 33 turbines, located near 
Saratoga, Iowa. MGE anticipates filing its formal application with the PSCW in March. If approved, construction of 
the project is expected to begin in early 2018, with an estimated capital cost of $107 million. 

Financing Plans: In January 2017, MGE issued $40 million of new long-term unsecured debt carrying an interest 
rate of 3.76% per annum over its 35-year term. The proceeds of this debt financing were used to refinance the 
maturing $30 million medium-term notes and, assist with the financing of additional capital expenditures. The 
covenants of this debt are substantially consistent with MGE's existing unsecured long-term debt. In accordance 
with applicable accounting guidance, MGE has classified the $30 million of maturing medium-term notes as long-
term debt on the consolidated balance sheets for 2016. MGE also plans to issue an additional $30 million of new 
long-term debt during 2017 to cover capital expenditures and other corporate obligations. 

The following discussion is based on the business segments as discussed in Footnote 20 of the Notes to 
Consolidated Financial Statements.

(3.5) 

In July 2015, the PSCW authorized MGE to freeze 2016 rates at 2015 levels for retail electric customers. 

  Deferral of fuel savings/fuel credit. During 2016, customers received a fuel credit on their bill related to the fuel 
savings of $21.1 million, which decreased electric revenues when compared to 2015. This amount was partially 
offset by the 2016 deferred fuel rules monitored costs. In January 2016, the PSCW lowered MGE's 2016 fuel 
rules monitored costs as a result of continued lower projected fuel costs in 2016. 

  Volume. During 2016, there was a 5.4% increase in total residential sales volumes compared to the same period 

in the prior year driven by increased customer demand due, at least in part, to more favorable weather 
conditions, as evidenced by the higher number of cooling degree days. 

  Adjustments to Revenue. 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 ending in 2015, which were recognized as 
operating revenues in our Nonregulated Energy Operations segment. 

MGE leases electric generating capacity from MGE Power Elm Road. MGE collects in rates the lease payments 
associated with the electric generating capacity as authorized by the PSCW. Any differential between estimated 
lease payments collected in rates and actual lease payments paid to MGE Power Elm Road are included in 
adjustments to revenues. 

 

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. 
These sales may also include bilateral sales to other utilities or power marketers. Generating units are 
dispatched by MISO based on cost considerations as well as reliability of the system. Sales to the market 
typically occur when MGE has more generation and purchases online than are needed for its own system 
demand. The excess electricity is then sold to others in the market. For 2016, market volumes increased 
compared to the same period in the prior year, reflecting increased opportunities for sales, and those sales were 
made at higher market prices. The revenue generated from these sales is included in fuel rules monitored costs. 
See fuel rules discussion in Footnote 16.b. of the Notes to Consolidated Financial Statements. 

  Other. During 2016, other items affecting electric operating revenues increased $2.4 million. MGE experienced 
an increase in residential and small commercial customers contributing to the increase in other electric revenue. 
Higher monthly on-peak sales also attributed to the increase. 

Electric fuel and purchased power 

Electric fuel and purchased power costs reflect an increase in internal generation volumes partially offset by a 
decrease in the volume of purchased power when compared to the prior year. Adjustments related to the regulatory 
recovery for fuel costs, known as fuel rules, decreased purchased power expense. These items are explained below. 

Fuel for electric generation 
The expense for fuel for internal electric generation increased $6.9 million during 2016 compared to 2015 due to the 
following: 

(In millions) 
Increase in volume........................................... $
Decrease in per-unit cost ..................................

This increase in expense reflects a 21.0% increase in internal generation volume delivered to the system primarily as 
a result of increased generation at WCCF based on market prices, partially offset by a 6.8% decrease in per-unit cost 
of internal electric generation, reflective of lower natural gas prices. 

Purchased power 
Purchased power expense decreased $24.9 million during 2016 compared to 2015 due to the following: 

(In millions) 
Decrease in volume .................................................. $ (15.2) 
Increase in per-unit cost............................................
3.0  
Change in fuel rule adjustments, net of recoveries .......
(12.7) 
Total ....................................................................... $ (24.9) 

The decrease in expense (before fuel rules adjustments) reflects a 21.1% decrease in the volume of power purchased 
from third parties primarily as a result of the increased internal generation, partially offset by a 5.2% increase in the 
per-unit cost of purchased power. 

Under 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.  

Electric operating and maintenance expenses 

Electric operating and maintenance expenses increased $2.5 million during 2016 compared to 2015. The following 
changes contributed to the net change: 

(In millions) 
Increased customer accounts costs .................................. $
Increased production costs .............................................

Increased other costs......................................................
Total ............................................................................ $

0.9  
0.7

0.4  
2.5  

For 2016, increased customer accounts costs are primarily related to higher customer billing expenses.  

Electric depreciation expense 

Electric depreciation expense decreased $0.8 million for 2016, compared to the prior year. A new depreciation study 
approved by the PSCW, effective January 1, 2016, resulted in a decrease in expense.

 

Rate/PGA changes. 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. 
Changes in PGA recoveries affect revenues but do not impact net income. 

The average retail rate per therm for 2016, decreased 5.0% compared to 2015, reflecting a $6.3 million decrease 
in natural gas commodity costs (recovered through the PGA), partially offset by an increase in fixed rate 
charges. 

•  Volume. For 2016, retail gas deliveries decreased 1.7% compared to the prior year. 

Cost of gas sold 

For 2016, cost of gas sold decreased by $9.3 million, compared to the prior year. The cost per therm of natural gas 
decreased 10.3%, which resulted in $7.6 million of decreased expense. The volume of gas purchased decreased 
2.2%, which resulted in $1.7 million of decreased expense. 

Gas operating and maintenance expenses 

Gas operating and maintenance expenses increased $1.0 million for 2016 compared to 2015. The following changes 
contributed to the net change.

For 2016, increased customer accounts costs are due to higher customer billing expenses. 

Gas depreciation expense 

Gas depreciation expense increased $1.4 million for 2016, compared to the prior year. This increase is primarily 
driven by an increase in gas utility plant in-service in 2016 and a new depreciation study approved by the PSCW, 
effective January 1, 2016. 

Nonregulated Energy Operations - MGE Energy and MGE 

For 2016 and 2015, net income at the nonregulated energy operations segment was $19.1 million and $20.1 million, 
respectively. The nonregulated energy operations are conducted through MGE Energy's subsidiaries: MGE Power 
Elm Road (the Elm Road Units) and MGE Power West Campus (WCCF), which have been formed to own and lease 
electric generating capacity to assist MGE. Carrying costs incurred during construction of the Elm Road Units and 
WCCF were recognized by MGE Power Elm Road and MGE Power West Campus over the period allowed for 
recovery in rates. The recovery period ended in 2015, contributing to a reduction in nonregulated earnings in 2016. 
The reduction in earnings was partially offset by an increase in lease revenue. 

Transmission Investment Operations - MGE Energy and MGE 

Transmission investment other income 

For 2016 and 2015, other income at the transmission investment segment was $8.4 million and $7.7 million, 
respectively. The transmission investment segment holds our interest in ATC and ATC Holdco, and its income 
reflects our equity in the earnings of ATC. ATC Holdco was formed in 2016. In the near term, it is expected that 
ATC Holdco will be pursuing transmission development opportunities that typically have long development and

Statements and "Other Matters" below for additional information concerning the transmission investments and 
summarized financial information regarding ATC. 

Consolidated Income Taxes - MGE Energy and MGE 

MGE Energy's effective income tax rate for 2016 and 2015 was 36.0% and 36.7%, respectively. MGE's effective 
income tax rate for 2016 and 2015 was 35.9% and 36.7%, respectively. The decrease in the effective tax rate is due 
in part to a combination of individually insignificant fluctuations. See Footnote 12 of the Notes to Consolidated 
Financial Statements for details of effective income tax rates for continuing operations. 

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 with respect to MGE 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, which holds our investment in ATC. The following table shows MGE Energy's noncontrolling 
interest, net of tax, reflected on MGE's consolidated statements of income:

(a)  MGE Transco holds an ownership interest in ATC. In July 2016, MGE's ownership interest in MGE 
Transco declined below a majority, resulting in MGE Energy's investment in MGE Transco being 
deconsolidated from MGE's consolidated financial statements. See Footnote 8 of the Notes to Consolidated 
Financial Statements for further discussion of noncontrolling interest. In December 2016, MGE's 
ownership interest in MGE Transco was transferred to MGE Energy, see Footnote 4 of the Notes to 
Consolidated Financial Statements for additional information.

  Rate changes. Rates charged to retail customers for 2015 were $14.4 million or 3.6% higher than those charged 

during 2014. 

In December 2014, the PSCW authorized MGE to increase 2015 rates for retail electric customers by 
$15.4 million or 3.8%. 

  Fuel Credit. During 2015 and 2014, customers received a fuel credit on their bill related to the fuel savings of 
$2.6 million and $6.5 million, respectively, which increased electric revenues when compared to 2014. 

  Adjustments to Revenue. 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. 

  Volume. During 2015, there was a 0.3% decrease in total retail sales volumes compared to 2014 primarily 

driven by lower use per residential customer. 

 

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. 
These sales may also include bilateral sales to other utilities or power marketers. Generating units are 
dispatched by MISO based on cost considerations as well as reliability of the system. Sales to the market 
typically occur when MGE has more generation and purchases online than are needed for its own system 
demand. The excess electricity is then sold to others in the market. For 2015, market volumes increased 
compared to 2014, reflecting increased opportunities for sales. In addition, market settlement resulted in lower 
revenue per kWh for 2015, reflecting lower market prices. The revenue generated from these sales is included 
in fuel rules monitored costs. See fuel rules discussion in Footnote 16.b. of the Notes to Consolidated Financial 
Statements. 

Electric fuel and purchased power 

Electric fuel and purchased power costs reflect an increase in internal generation volumes during 2015 partially 
offset by a decrease in the volume of purchased power when compared to 2014. Adjustments related to the 
regulatory recovery for fuel costs, known as fuel rules, increased purchased power expense. These items are 
explained below. 

Fuel for electric generation 
The expense for fuel for internal electric generation increased $11.0 million during 2015 compared to 2014 due to 
the following: 

(In millions) 
Increase in per-unit cost ................................... $
Increase in volume...........................................
Total .............................................................. $

5.8  
5.2

Purchased power 
Purchased power expense increased $8.0 million during 2015 compared to 2014 due to the following: 

(In millions) 
Decrease in volume .................................................. $ (11.0) 
Decrease in per-unit cost...........................................
(2.8) 
Change in fuel rule adjustments, net of recoveries .......
21.8  
Total ....................................................................... $
8.0  

The decrease in expense (before fuel rules adjustments) reflects a 3.8% decrease in the per-unit cost of purchased 
power and a 12.8% decrease in the volume of power purchased from third parties primarily as a result of increased 
internal generation. 

Under 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.  

Electric operating and maintenance expenses

For 2015, increased transmission costs are primarily related to an increase in transmission reliability enhancements. 
In addition, increased administrative and general costs are primarily due to increased pension and other 
postretirement benefits costs predominantly driven by a reduction in the discount rate, which has the effect of 
increasing the related costs. Decreased customer account costs are primarily related to lower uncollectible accounts 
receivable.  

Electric depreciation expense 

Electric depreciation expense increased $3.0 million for 2015 compared to 2014. This increase is primarily related to 
the completion of the Columbia environmental project. The systems and equipment for Unit 2 and Unit 1 were 
placed into service in April 2014 and July 2014, respectively. 

Other Electric Income 

Other electric income decreased $2.4 million, primarily due to AFUDC equity related to the completion of the 
Columbia environmental project. Unit 2 and Unit 1 were placed into service in April and July 2014, respectively.

(78.0) 

•  Volume. For 2015, retail gas deliveries decreased 27.0% compared to 2014, as a result of extremely cold 
weather experienced in the first quarter of 2014. The decrease was also attributable to a large commercial 
customer's decision to purchase gas from a third party supplier and to use MGE's facilities for the transport of 
that gas. While the shift affects revenues, the impact to gas income of this shift is not material as we do not earn 
margin on the natural gas commodity cost billed to customers. 

 

Rate/PGA changes. In December 2014, the PSCW approved changes to customer rates and rate design for gas 
service. Rates were reduced by 2.0%, effective January 1, 2015. Gas rate design consists of a fixed monthly 
customer charge and a variable charge tied to actual usage, in addition to the separate charge for natural gas 
commodity costs that is recovered through the PGA. The change shifted more of the rate recovery to the 
monthly charge, reflecting the related fixed costs of providing gas services, and reduced the variable usage-
based charge. Thus, gas net income was more evenly distributed during the year and less sensitive to weather. 

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. Changes in PGA recoveries 
affect revenues but do not impact net income. 

The average retail rate per therm for 2015 decreased 12.8% compared to 2014, reflecting a $28.7 million 
decrease in natural gas commodity costs (PGA) offset by an $8.2 million increase (comprised of a decrease in 
variable rate costs offset by an increase in fixed rate charges) related to rate design changes. As noted 
previously, as a result of the rate design changes, revenues in the first and fourth quarters, when usage is higher, 
were lower than in past years; and revenues in the second and third quarters, when usage is lower, were higher 
than in past years. 

 

Transportation and other effects. During 2015, transportation and other effects increased $1.3 million primarily 
attributable to a large commercial customer's decision to purchase gas from a third party supplier and to use 
MGE's facilities for the transport of that gas. The impact to gas income of this shift is not material.

Cost of gas sold 

For 2015, cost of gas sold decreased by $67.5 million compared to 2014. The volume of gas purchased decreased 
26.8%, which resulted in $38.5 million of decreased expense. The cost per therm of natural gas decreased 27.6%, 
which resulted in $29.0 million of decreased expense. 

Gas operating and maintenance expenses 

Gas operating and maintenance expenses decreased $1.2 million for 2015 compared to 2014. The following changes 
contributed to the net change.

(1.2) 

For 2015, decreased customer service costs are due to lower Focus on Energy payments, Wisconsin's statewide 
energy efficiency and renewable resource program to promote energy efficiency on customer's premises. Decreased 
customer accounts costs are due to lower uncollectible accounts receivable. Increased administrative and general 
costs are primarily due to increased pension and other postretirement benefit costs predominantly driven by a 
reduction in the discount rate. 

Nonregulated Energy Operations - MGE Energy and MGE 

For 2015 and 2014, net income at the nonregulated energy operations segment was $20.1 million and $19.3 million, 
respectively. The nonregulated energy operations are conducted through MGE Energy's subsidiaries: MGE Power 
Elm Road (the Elm Road Units) and MGE Power West Campus (WCCF), which have been formed to own and lease 
electric generating capacity to assist MGE. 

Transmission Investment Operations - MGE Energy and MGE 

Transmission investment other income 

For 2015 and 2014, other income at the transmission investment segment was $7.7 million and $9.2 million, 
respectively. The transmission investment segment holds our interest in ATC, and its income reflects our equity in 
the earnings of ATC. See Footnote 4.b. of the Notes to Consolidated Financial Statements and "Other Matters" 
below for additional information concerning ATC and summarized financial information regarding ATC. 

All Other Operations - MGE Energy and MGE 

Other income 

The increase in all other income primarily results from a decrease in voluntary contributions. 

Consolidated Income Taxes - MGE Energy and MGE 

Both MGE Energy's and MGE's effective income tax rate for 2015 and 2014, was 36.7% and 37.5%, respectively. 
The decrease in the effective tax rate is due in part to a higher estimated domestic manufacturing deduction, offset 
by lower AFUDC equity earnings in 2015. See Footnote 12 of the Notes to Consolidated Financial Statements for 
details of effective income tax rates for continuing operations. 

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 with respect to MGE 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

operating activities for 2016, primarily due to increased accounts payable, decreased inventories, and decreased 
receivable margin, partially offset by increased unbilled revenues, increased receivables, and decreased current 
liabilities. The decrease in current liabilities includes a fuel credit, approved in August 2015, of $8.3 million that 
customers received on their bill throughout 2016 and a one-time fuel credit, approved in July 2016, of $15.5 million 
that customers received on their bill in September 2016. 

Working capital accounts (excluding prepaid and accrued taxes) resulted in $5.0 million in cash provided by 
operating activities for 2015, primarily due to decreased receivables and decreased unbilled revenues, partially offset 
by increased inventories, decreased accounts payable, and decreased current liabilities. The decrease in current 
liabilities includes a fuel credit of $2.6 million that customers received on their bill in the period September through 
December 2015 related to the 2015 fuel savings and $11.4 million of deferred fuel related cost savings to be

For 2015, net short-term debt repayments were $7.0 million. There were no short-term debt repayments for 2014. 

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, above the PSCW authorized 
amount of $43 million, 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, 
2016, is 60.2%, as determined under the calculation used in the rate proceeding. This restriction did not impact 
MGE's payment of dividends in 2016. Cash dividends of $50.0 million and $30.0 million were paid by MGE to 
MGE Energy in 2016 and 2015, respectively. In 2016, MGE also transferred its ownership interest in MGE Transco 
to MGE Energy in the form of a dividend in kind of $15.8 million. 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, 2016, approximately $338.5 million was available for the payment of dividends under this covenant.

Borrowings under the Credit Agreements may bear interest at a rate based upon either a "floating rate" or a 
"Eurodollar Rate" adjusted for statutory reserve requirements, plus an adder based upon the credit ratings assigned 
to MGE's senior unsecured long-term debt securities. The "floating rate" is calculated on a daily basis as the highest 
of a prime rate, a Federal Funds effective rate plus 0.5% per annum, or a Eurodollar Rate for a one-month interest 
period plus 1%. The "floating rate" adder ranges from zero to 0.125%. The "Eurodollar Rate" is calculated as 
provided in the Credit Agreements. The "Eurodollar Rate" adder ranges from 0.625% to 1.125%.  

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, 2016, the ratio of consolidated debt to consolidated total capitalization for each of 
MGE Energy and MGE, as calculated under the credit agreements' covenant, were 34.8% and 36.5%, respectively. 
See Footnote 10 of the Notes to Consolidated Financial Statements for additional information regarding the credit 
facilities.

Credit Ratings 

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

None of MGE Energy's or MGE's borrowing is subject to default or prepayment as a 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.

transport of coal. See Footnote 17.a. of the Notes to Consolidated Financial Statements. 

(f)  Other obligations are primarily related to investment commitments, easements, environmental projects, fuel 

credit, and uncertain tax positions. 

The above amounts do not include any contributions for MGE's pension and postretirement plans. Voluntary 
contributions to the qualified plans for 2017 were $6.0 million, which were paid in January 2017. MGE does not 
expect to make contributions to the plans for 2018. The contributions for years after 2018 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 to the plans. 

The above amounts do not include future capital calls by ATC and ATC Holdco. On January 31, 2017, MGE 
Transco made a $1.4 million capital contribution to ATC, and on January 10, 2017, MGEE Transco made a 
$0.2 million capital contribution to ATC Holdco. The amount and timing of future capital calls is uncertain and 
primarily dependent on the operations and expansion of ATC and ATC Holdco.  

MGE Energy's and MGE's commercial commitments as of December 31, 2016, representing commitments triggered 
by future events and including financing arrangements to secure obligations of MGE Energy and MGE, are as

Other Matters 

ATC 

In 2013, several parties filed the first complaint with the FERC seeking to reduce the base return on equity (ROE) 
used by MISO transmission owners, including ATC, "due to changes in the capital markets." The complaint alleged 
that the MISO ROE should not exceed 9.15%, the equity components of hypothetical capital structures should be 
restricted to 50%, and the relevant incentive ROE adders should be discontinued. At the time, MISO's base ROE 
was 12.38% and ATC's base ROE was 12.2%. In February 2015, a second complaint was filed for the period 
February 2015 through May 2015 with the FERC requesting a reduction in the base ROE used by MISO  

45 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
transmission owners, including ATC, to 8.67%, with a refund effective date retroactive to the filing date of the 
complaint. In June 2016, an administrative law judge issued an initial decision for the second complaint that would 
reduce the transmission owner's base ROE to 9.7%. The initial decision will be reviewed by FERC. It is anticipated 
FERC will issue an order on this issue by mid-2017. On September 28, 2016, FERC issued an order on the first 
complaint, for the period November 2013 through February 2015, reducing the base ROE to 10.32%. This base ROE 
also became effective September 28, 2016, and will apply to future periods until FERC rules in the second 
complaint, at which time the base ROE ordered by FERC in the second complaint will prospectively become the 
authorized base ROE. 

In January 2015, FERC accepted the transmission owner's request for a 50 basis-point incentive ROE adder for 
participating in MISO. The adder became effective January 6, 2015, subject to refund, and FERC accepted the 
transmission owner's request to defer collection of the adder pending the outcome of the first ROE complaint 
proceeding. 

Any change to ATC's ROE could result in lower equity earnings and distributions from ATC in the future. Our share 
of ATC's earnings reflects a pre-tax charge of $1.9 million and $2.3 million for 2016 and 2015, respectively, 
recorded by ATC for this matter representing its estimate of its refund liability. We derived approximately 6.8% and 
6.4% of our net income for 2016 and 2015, respectively, from our investment in ATC. 

Critical Accounting Estimates - MGE Energy and MGE 

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

Unbilled Revenues 

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

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

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

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

actually delivered to customers. 

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

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

Allowance for Doubtful Accounts 

MGE maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to 
make required payments. It determines the allowance based on historical write-off experience, regional economic 
data, and review of the accounts receivable aging. MGE reviews its allowance for doubtful accounts monthly.  

46 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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. 

  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 2016, MGE used an assumed return on assets of 7.65% for pension and 6.96% 
for other postretirement benefits. In 2017, the pension asset assumption will decrease from 7.65% to 7.40%. 
MGE will decrease the postretirement benefit assumption from 6.96% to 6.78% in 2017. 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 $3.3 million, before taxes. 

  Discount rate. The discount rate represents the rate at which pension obligations could effectively be settled on 
a present-value basis. MGE uses high-grade bond yields as a benchmark for determining the appropriate 
discount rate. At December 31, 2015, MGE refined its methodology for using discount rates to measure the 
components of net periodic benefit cost. The refined methodology uses individual spot rates, instead of a 
weighted average of the yield curve spot rates, for measuring the service cost and interest cost components. 
Holding other assumptions constant, a 0.5% reduction in the discount rate on the obligation balance at 
December 31, 2016, would increase annual pension and other postretirement cost by approximately 
$2.8 million, before taxes. 

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

care charges. 

  Mortality rate assumption. Expected mortality rates are used in the valuation to determine the expected duration 
of future benefit payments to the plan participants. In 2016, the Society of Actuaries released new mortality 
tables and projection scales. At December 31, 2016, the Company adopted a modified version of these tables 
that were developed by a third party actuary. 

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  

47 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 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 commodity hedging in 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 
costs. The accounting for these regulatory assets and liabilities is in accordance with regulatory accounting 
standards. 

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

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

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

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

Commodity Price Risk 

MGE has commodity price risk exposure with respect to the price of natural gas, electricity, coal, emission credits, 
and oil. MGE'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 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. 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 in a year is determined in the following year and is then reflected 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 is required to defer costs, less any excess 
revenues, if the actual electric fuel costs exceed 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 2017, fuel and purchased power costs 
included in MGE's base fuel rates are $101.9 million. See Footnote 16 of the Notes to Consolidated Financial 
Statements for additional information. 

MGE recovers the cost of natural gas in its gas utility 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 utility 
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, 2016, the 
fair value of these instruments exceeded their cost basis by $1.3 million. Under the PGA clause and electric fuel 
rules, MGE may include in the costs of fuel (natural gas or power) the costs and benefits of the aforementioned fuel 
price risk management tools. Because these costs/benefits are recoverable, the related unrealized loss/gain has been 
deferred on the consolidated balance sheets as a regulatory asset/liability. 

MGE has also entered into a 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, 2016, reflects a loss position of $50.6 million. 

Interest Rate Risk 

Both MGE Energy and MGE may have short term borrowings at varying interest rates. MGE issues commercial 
paper for its short-term borrowings, while MGE Energy draws from its current credit facility to meet its short-term 
borrowing needs. 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.  

49 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
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 $3.3 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 8.36% 
and 1.39% during the years ended December 31, 2016, and 2015, respectively. 

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, 2016, 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 1,682 square miles in Wisconsin. Based on results for 
December 31, 2016, 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 (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. 
Based on our assessment under the framework in the Internal Control - Integrated Framework (2013), our 
management concluded that our internal control over financial reporting was effective as of December 31, 2016. 

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, 2016, 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, 2016 and 
2015, and the results of their operations and their cash flows for each of the three years in the period ended 
December 31, 2016, in conformity with accounting principles generally accepted in the United States of America. In 
addition, in our opinion, the financial statement 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, 2016, based on criteria established in Internal Control - 
Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission 
(COSO). The Company's management is responsible for these financial statements and financial statement 
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, 2016, 2015, and 2014 

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

1. 

Summary of Significant Accounting Policies. 

a.  Basis of Presentation - MGE Energy and MGE. 

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

b.  Principles of Consolidation - MGE Energy and MGE. 

MGE, a wholly owned subsidiary of MGE Energy, is a regulated electric and gas utility headquartered in 
Madison, Wisconsin. MGE Energy and MGE consolidate all majority owned subsidiaries in which it has 
controlling influence.  

Additional wholly owned subsidiaries of MGE Energy include CWDC, MAGAEL, MGE Power, MGE 
State Energy Services, MGE Services, MGE Transco, MGEE Transco, and NGV Fueling Services. 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 Transco and MGEE Transco are nonregulated 
entities formed to manage the investments in ATC and ATC Holdco, respectively. On December 1, 2016, 
MGE's ownership interest in MGE Transco was transferred to MGE Energy. See Footnote 4 for further 
discussion of the transfer of MGE's investment in MGE Transco. 

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. 

Prior to December 1, 2016, MGE Transco was jointly owned by MGE Energy and MGE. MGE's 
ownership interest in MGE Transco declined below a majority in July 2016. As a result of the change in 
majority ownership, MGE deconsolidated MGE Energy's proportionate share of the equity in MGE 
Transco. See Footnote 8 for further discussion regarding the deconsolidation of noncontrolling interest.  

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

c.  Use of Estimates - MGE Energy and MGE. 

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

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

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

Restricted Cash 
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 and cash deposits held by third parties. As of December 31, 2016 and 2015, there was 
$3.7 million and $2.9 million, respectively, of cash deposits held by third parties. These are included in 
"Other current assets" on the consolidated balance sheets. 

Receivable – Margin Account 
Cash amounts held by counterparties as margin for certain financial transactions are recorded as 
receivable – margin account in "Other current assets" on the consolidated balance sheets. As of 
December 31, 2016 and 2015, the receivable – margin account balance of $1.3 million and $2.3 million, 
respectively, is shown net of any collateral posted against derivative positions. As of December 31, 2016, 
no cash collateral was posted against derivative positions. As of December 31, 2015, there was 
$1.0 million of 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. 

e.  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 manages this concentration and the related credit risk through its credit and collection policies, 
which are consistent with state regulatory requirements. 

f. 

Inventories - MGE Energy and MGE. 

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

REC allowances are included in "Materials and supplies" on the consolidated balance sheets 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 balance as of December 31, 2016 and 2015, was 
$0.3 million. 

g.  Chattel Paper Agreements - 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. 
The energy-related equipment installed at the customer sites is used to secure the customer loans. MGE is 
a 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, 2017. 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. The loan balances outstanding at 
December 31, 2016, approximate the fair value of the energy-related equipment acting as collateral. 
MGE accounts for these agreements as secured borrowings.

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

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

i.  Debt Issuance Costs - MGE Energy and MGE. 

Premiums, discounts, and expenses incurred with the issuance of outstanding long-term debt are 
amortized over the life of the debt issue. Any call premiums or unamortized expenses associated with 
refinancing higher-cost debt obligations used to finance utility-regulated assets and operations are 
amortized consistent with regulatory treatment of those items. These costs are included as a direct 
deduction to the related debt liability on the consolidated balance sheets. 

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(a) 
Gas(a) 
Nonregulated  

2016 
2.5 % 
2.1 % 
2.3 % 

2015 
2.6 % 
1.7 % 
2.4 % 

2014 
2.6 % 
1.7 % 
2.4 % 

(a)  In December 2015, the PSCW approved new depreciation rates, which were implemented and 

became effective as of January 1, 2016. 

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 the 
consolidated 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 18 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, 2016 
and 2015, MGE had over collected $0.9 million and $0.8 million, respectively. These amounts are 
included in "Regulatory liabilities - current" on the consolidated balance sheets. 

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.  

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 in a year is determined in the following year and is then reflected 
in future billings to electric retail customers. Such deferred amounts will be recognized in "Purchased 
power" expense in MGE Energy's and MGE's consolidated income statements 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 16.b. for further information regarding the regulatory rules applicable 
to the recovery of electric fuel costs. 

p.  Regional Transmission Organizations - MGE Energy and MGE. 

MGE reports on a net basis transactions on the MISO markets in which it buys and sells power within the 
same hour to meet electric energy delivery requirements. This treatment resulted in a $77.2 million, a 
$68.6 million, and a $91.1 million reduction to sales to the market and purchase power expense for 
MISO markets for the years ended December 31, 2016, 2015, and 2014, respectively. 

q.  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 shareholder's 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 shareholder's capital (AFUDC-equity 
funds) is shown as an item within "Other income." For both 2016 and 2015, as approved by the PSCW, 
MGE capitalized AFUDC-debt and equity on 50% of applicable average construction work in progress at 
7.93%. For 2014, MGE capitalized AFUDC-debt and equity on 50% of applicable average construction 
work in progress at 8.21%. For 2016, 2015, and 2014, MGE received specific approval to recover 100% 
AFUDC on certain environmental costs for Columbia. These amounts are recovered under the 
ratemaking process over the service lives of the related properties.  

r. 

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 and are considered to have significant influence 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.

s.  Capitalized Software Costs - MGE Energy and MGE. 

Property, plant, and equipment includes the net book value of capitalized costs of internal use software 
totaling $12.3 million and $12.0 million at December 31, 2016 and 2015, respectively. During 2016, 
2015, and 2014, MGE recorded $3.0 million, $2.2 million, and $1.6 million, respectively, of amortization 
expense related to these costs. These costs are amortized on a straight-line basis over the estimated useful 
lives of the assets. For internal use software, the useful lives range from five to ten years. 

t. 

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, 2016, 2015, and 2014. 

u.  Income Taxes and Excise Taxes - MGE Energy and MGE. 

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

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

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

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

Excise taxes 
MGE Energy, through its utility operations, pays a state license fee tax in lieu of property taxes on 
property used in utility operations. License fee tax is calculated as a percentage of adjusted operating 
revenues of the prior year. The electric tax rate is 3.19% for retail sales and 1.59% for sales of electricity 
for resale by the purchaser. The tax rate on sales of natural gas is 0.97%. The tax is required to be 
estimated and prepaid in the year prior to its computation and expensing. License fee tax expense, 
included in "Other general taxes," was $14.5 million, $14.7 million, and $14.6 million for the years 
ended December 31, 2016, 2015, and 2014, respectively. 

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

v.  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 

66 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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. 

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 commodity prices. 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 are 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 sheets related to its interest in this VIE:

Long-term debt excluding debt issuance costs consists of $62.6 million at December 31, 2016, 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, 2016, 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 collected 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 was recognized over the period allowed for recovery in rates which ended in 2015.  

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. At December 31, MGE has included the following significant accounts on its consolidated 
balance sheets related to its interest in this VIE:

Long-term debt excluding debt issuance costs consists of $45.1 million at December 31, 2016, 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 0.65 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, 2016, 
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 were 
recovered in rates over a 10 year period that started in 2005 and ended in 2015.  

c.  Other Variable Interest Entities. 

MGE has a variable interest in entities through purchase power agreements relating to purchased energy 
from the facilities covered by the agreements. As of December 31, 2016 and 2015, MGE had 51 
megawatts and 61 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.

in ATC Holdco. In July 2016, MGE's ownership interest in MGE Transco declined below a 
majority, resulting in MGE Energy's investment in MGE Transco being deconsolidated from MGE's 
consolidated financial statements. See Footnote 8 for further discussion of noncontrolling interest. In 
December 2016, MGE's ownership interest in MGE Transco was transferred to MGE Energy, see 
"ATC and ATC Holdco" below for additional information. 

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

b.  ATC and ATC Holdco. 

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, as of 
December 1, 2016, is owned by MGE Energy. ATC Holdco was formed by several members of ATC, 
including MGE Energy, to pursue electric transmission development and investments outside of 
Wisconsin. The ownership interest in ATC Holdco is held by MGEE Transco, a wholly-owned 
subsidiary of MGE Energy. 

MGE Transco and MGEE Transco have accounted for their investment in ATC and ATC Holdco, 
respectively, under the equity method of accounting. For the years ended December 31, 2016, 2015, and 
2014, MGE Transco recorded the following:

(a)  As of December 31, 2016, MGE Transco recorded a $2.1 million receivable from ATC for a cash 

dividend received in January 2017. 

ATC Holdco's activities commenced in late December 2016 and had an immaterial impact on results of 
operations, cash flows, and financial condition. 

At December 31, 2016 and 2015, MGE Transco held a 3.6% ownership interest in ATC. At 
December 31, 2016, MGEE Transco held a 4.0% ownership interest in ATC Holdco. On January 31, 
2017, MGE Transco made a $1.4 million capital contribution to ATC, and on January 10, 2017, MGEE 
Transco made a $0.2 million capital contribution to ATC Holdco. 

In June 2016, the PSCW required MGE to transfer its interest in ATC to MGE Energy, which was to be 
completed by December 31, 2022. The requirement arose in the context of requests for regulatory 
approvals by several owners of ATC in connection with a reorganization of ATC. MGE's ownership 
interest in ATC, held through MGE Transco, was transferred net of deferred tax liabilities to 
MGE Energy by way of a dividend in kind of $15.8 million as of December 1, 2016. As a result of the 
transfer, MGE's ownership interest in MGE Transco was completely eliminated in favor of MGE Energy. 
See Footnote 12 for further discussion of the transfer of deferred tax liabilities. The change had no effect 
on MGE Energy's consolidated financial statements.

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, at December 31, 2016, accounts for 30% (225 MW) of MGE's net summer rated 
capacity. Power from this facility is shared in proportion to each company's ownership interest. At 
December 31, 2016, MGE had a 22.0% 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 was $39.5 million, $38.2 million, and $28.1 million for the years ended December 31, 2016, 
2015, and 2014, respectively. 

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's gross utility plant in service, and the related 
accumulated depreciation reserves at December 31 were as follows:

In 2016, MGE and WPL negotiated an amendment to the existing Columbia joint operating agreement, 
that has been approved by the PSCW, under which MGE will have the option to reduce its obligation to 
pay certain capital expenditures (other than SCR-related expenditures) at Columbia in exchange for a 
proportional reduction in MGE's ownership in Columbia. On January 1 of each year, beginning in 2017 
and ending June 1, 2020, the ownership percentage will be adjusted, through a partial sale, based on the 
amount of capital expenditures foregone. In December 2016, MGE jointly filed a request with the co-
owners of Columbia for FERC approval of the amendment to the Columbia joint operating agreement, 
effective January 1, 2017. MGE currently expects to receive FERC's decision on the amendment in 2017. 

During 2016, MGE accrued $14.8 million of 2016 capital expenditures that MGE has forgone as part of 
the ownership transfer agreement with WPL. As of December 31, 2016, MGE classified $14.8 million of 
Columbia assets as held-for-sale on the consolidated balance sheets. In January 2017, MGE reduced its 
ownership interest in Columbia from 22.0% to 20.4% through the partial sale of plant assets to WPL.

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, at December 31, 2016, 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 was $21.2 million, $20.9 million, and $20.3 million for the 
years ended December 31, 2016, 2015, and 2014, respectively. MGE Power Elm Road's interest in the 
portion of the Elm Road Units in-service and the related accumulated depreciation reserves at 
December 31 were as follows:

c.  WCCF. 

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

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

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. 
Management believes 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 18 for further discussion. 

Conservation Costs 
MGE has received regulatory treatment for certain conservation expenditures. The expenditures are used for 
Focus on Energy programs, Wisconsin's statewide energy efficiency and renewable resource program, to 
promote energy efficiency on the customer's premises. Costs for Focus on Energy 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. 

Debt Related Costs 
This balance includes debt issuance costs of extinguished debt and other debt related expenses, including 
make-whole premiums. 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. 

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 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. See Footnote 15 for further discussion.

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 17.c. 

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 a regulatory asset or liability. The 
unfunded status represents future expenses that are expected to be recovered in rates. See Footnote 13 for 
further discussion. 

Deferred Fuel Savings  
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 is adjusted in future billings to electric retail customers. See Footnote 16.b. for further discussion.  

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 
has collected the carrying costs in rates over a six year period that ended in 2015. All other costs are collected 
in rates over a one to two year period.  

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

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

Renewable Energy Credits 
MGE receives renewable energy credits from certain purchase power 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. 

74 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
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, 2016 and 2015, 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.  

During the years ended December 31, 2016 and 2015, MGE Energy paid $41.8 million (or $1.21 per 
share) and $40.0 million (or $1.16 per share), respectively, in cash dividends on its common stock. 
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, above the 
PSCW authorized amount that MGE may pay MGE Energy if its common equity ratio, calculated in the 
manner used in the rate proceeding, is less than 55%. See Footnote 9 for further discussion of the 
mortgage indenture covenants. During the years ended December 31, 2016 and 2015, MGE paid 
$50.0 million and $30.0 million, respectively, in cash dividends to MGE Energy. In 2016, MGE also 
transferred its ownership interest in MGE Transco to MGE Energy in the form of a dividend in kind of 
$15.8 million. See Footnote 4 for further information.

(a)  MGE Power Elm Road and MGE Power West Campus are not subsidiaries of MGE; however, they have 
been consolidated in the consolidated financial statements of MGE (see Footnote 2). MGE Power Elm 
Road and MGE Power West Campus are 100% owned by MGE Power, and MGE Power is 100% owned 
by MGE Energy. MGE Energy's proportionate share of the equity and net income (through its wholly 
owned subsidiary MGE Power) of MGE Power Elm Road and MGE Power West Campus is classified 
within the MGE consolidated financial statements as noncontrolling interest. 

(b)  At December 31, 2016, MGE Energy is the owner of MGE Transco. In July 2016, MGE's ownership 

interest in MGE Transco declined below a majority as a result of continued funding of ATC capital 
contributions by MGE Energy. As a result of the change in majority ownership in MGE Transco, MGE 
deconsolidated MGE Energy's proportionate share of the equity in MGE Transco. The change in 
consolidation was applied prospectively by reducing its investment and noncontrolling interest on MGE's 
consolidated financial statements. The change had no effect on MGE Energy's consolidated financial

classified as noncontrolling interest was deconsolidated from MGE's financial statements. No gain or 
loss was recognized in July 2016 due to MGE ceasing to have a controlling financial interest.

(a)  MGE's utility plant is subject to the lien of its Indenture of Mortgage and Deed of Trust, under which 
its first mortgage bonds are issued. The Mortgage Indenture provides that dividends or any other 
distribution or purchase of shares may not be made if the aggregate amount thereof since 
December 31, 1945 would exceed the earned surplus (retained earnings) accumulated subsequent to 
December 31, 1945. As of December 31, 2016, approximately $338.5 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)  MGE had $30 million of medium-term notes mature in January 2017. MGE issued $40 million of 

new long-term unsecured debt on January 13, 2017, to refinance the maturing $30 million medium-
term notes and assist with the financing of additional capital expenditures. The new debt carries an 
interest rate of 3.76% per annum over its 35-year term. The covenants of this debt are substantially 
consistent with MGE's existing unsecured long-term debt. In accordance with applicable accounting 
guidance, MGE has classified the $30 million of maturing medium-term notes as long-term debt on 
the consolidated balance sheets for the year ended December 31, 2016.

(d)  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. 

(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, 2016, MGE was 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 0.65 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 
WCCF pursuant to a long-term lease. As of December 31, 2016, MGE Power West Campus was 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, 2016, 
MGE Power Elm Road was in compliance with the covenant requirements.

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

a.  MGE Energy. 

At December 31, 2016, MGE Energy had an unsecured, committed revolving line of credit of 
$50 million expiring June 1, 2020. At December 31, 2016, no borrowings were outstanding under this 
facility. 

The agreement requires MGE Energy to maintain a ratio of its consolidated indebtedness to consolidated 
total capitalization not to exceed a maximum of 65%. A change in control constitutes a default under the 
agreement. Change in control events are defined as (i) a failure by MGE Energy to hold 100% of the 
outstanding voting equity interest in MGE or (ii) the acquisition of beneficial ownership of 30% or more 
of the outstanding voting stock of MGE Energy by one person or two or more persons acting in concert. 
As of December 31, 2016, MGE Energy was 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, 2016, MGE had two unsecured, committed revolving lines of credit for a total of 
$100 million expiring June 1, 2020. At December 31, 2016, no borrowings were outstanding under these 
facilities, and MGE had no commercial paper outstanding. 

The agreements require MGE to maintain a ratio of consolidated debt to consolidated total capitalization 
not to exceed a maximum of 65%. The ratio calculation excludes assets, liabilities, revenues, and 
expenses included in MGE's financial statements as the result of the consolidation of VIEs, such as MGE 
Power West Campus and MGE Power Elm Road. A change in control constitutes a default under the 
agreements. Change in control events are defined as (i) a failure by MGE Energy to hold 100% of the 
outstanding voting equity interest in MGE or (ii) the acquisition of beneficial ownership of 30% or more 
of the outstanding voting stock of MGE Energy by one person or two or more persons acting in concert. 
As of December 31, 2016, MGE was 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 accounting standard clarifies that fair value should 
be based on the assumptions market participants would use when pricing the asset or liability including 
assumptions about risk. The standard also establishes a three level fair value hierarchy based upon the 
observability of the assumptions used and requires the use of observable market data when available. The 
levels are: 

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

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

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

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

At December 31, 2016 and 2015, the carrying amount of cash, cash equivalents, and outstanding 
commercial paper approximates fair market value due to the short maturity of those investments and 
obligations. The estimated fair market value of MGE Energy's and MGE's 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 financial instruments 
are as follows:

        (b)     These amounts are shown gross and exclude $1.0 million of collateral that was posted against 
                  derivative positions with counterparties as of December 31, 2015. 

No transfers were made in or out of Level 1 or Level 2 for the year ended December 31, 2016. 

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 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 purchased power agreement (see Footnote 15) 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.

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.

(c)  MGE's exchange-traded derivative contracts, over-the-counter party transactions, purchased power

Income Taxes. 

a.  MGE Energy and MGE Income Taxes. 

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

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

(In thousands) 
Current payable:

Our state 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, 2016, both MGE Energy and MGE 
had approximately $1.4 million of state tax net operating loss deductions subject to a valuation allowance 
that expire between 2020 and 2023 if unused. 

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

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

A tabular reconciliation of unrecognized tax benefits and interest from January 1, 2014, to December 31, 
2016, is as follows:

Unrecognized tax benefits are liabilities shown with "Other deferred liabilities" on the consolidated 
balance sheets. The interest component is offset by a regulatory asset. 

At December 31, 2016, 2015, and 2014, MGE Energy and MGE had unrecognized tax benefits primarily 
related to temporary tax differences associated with the change in income tax method of accounting for 
electric generation and electric and gas distribution repairs. In addition, at December 31, 2016, 
MGE Energy and MGE had unrecognized tax benefits relating to permanent differences and tax credits 
of less than $0.1 million. There were no unrecognized tax benefits at December 31, 2015 or 2014, related 
to federal permanent differences and tax credits.  

The unrecognized tax benefits at December 31, 2016, are not expected to significantly increase or 
decrease within the next twelve months. In addition, statutes of limitations will expire for MGE Energy 
and MGE tax returns. The impact of the statutes of limitations expiring is not anticipated to be material. 
The following table shows tax years that remain subject to examination by major jurisdiction:

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 defined 
contribution 401(k) benefit plans for its employees and retirees. MGE's costs for the 401(k) plans were 
$3.1 million, $2.8 million, and $2.5 million in 2016, 2015, and 2014, 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.

(a)  In 2015, MGE refined its methodology for using discount rates to measure the components of net 

periodic benefit cost. The refined methodology uses individual spot rates, instead of a weighted 
average of the yield curve spot rates, for measuring the service cost and interest cost components. 

The weighted-average assumptions used to determine the net periodic cost were as follows for the years 
ended December 31:

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. 

d.  Investment Strategy. 

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

The asset allocation for MGE's pension plans at the end of 2016 and 2015, and the target allocation for 
2017, by asset category, follows: 

Equity securities(a) ..................................
Fixed income securities ..........................

(a) Target allocations for equity securities are broken out as follows: 45.5% United States equity, 17.5% 
non-United States equity. 

The fair value of plan assets for the postretirement benefit plans is $43.2 million and $40.2 million at the 
end of 2016 and 2015, respectively. Of this amount, $37.0 million and $34.1 million at the end of 2016 
and 2015, 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 
health benefit trusts for payment of retiree health premiums. The asset allocation for the insurance 
continuance fund is determined by the life insurer. The target asset allocation for the health benefit trusts 
are established based on a similar investment strategy as assets held in the master pension trust, with 
consideration for liquidity needs in the health benefit trusts. 

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, 2016. 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, 2016, 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. 

Pension and other postretirement benefit plan investments are recorded at fair value. See Footnote 11 for 
more information regarding the fair value hierarchy.  

The following descriptions are the categories of underlying plan assets held within the pension and other 
postretirement benefit plans as of December 31, 2016: 

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

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

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

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

Insurance Continuance Fund (ICF) – The ICF is a supplemental retirement plan that includes assets that 
have been segregated and restricted to pay retiree term life insurance premiums. 

Fixed Rate Fund – The Fixed Rate fund is supported by an underlying portfolio of fixed income 
securities, including public bonds, commercial mortgages, and private placement bonds. Public market 
data and GAAP reported market values are used when available to determine fair value. 

All of the fair values of MGE's plan assets are measured using net asset value, except for cash and cash 
equivalents which are considered level 1 investments. The fair values of MGE's plan assets by asset 
category are as follows:

g.  Expected Cash Flows. 

Contributions to the qualified plans for 2017 were $6.0 million, which was paid in January 2017. MGE 
does not expect to make contributions to the plans for 2018. The contributions for years after 2018 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 2016, MGE made $14.5 million in employer contributions to its pension and postretirement plans.

Share-Based Compensation - MGE Energy and MGE. 

Under MGE Energy's Director Incentive Plan and Performance Unit Plan, non-employee directors and 
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 plans' provisions, these 
awards are subject to prescribed vesting schedules and must be settled in cash. Accordingly, no shares of 
common stock will be issued in connection with the plans.  

On the grant date, MGE Energy and MGE measure the cost of the director or 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, 2016, 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.  

Units granted under the Director Incentive Plan are subject to a three-year vesting schedule. The most recent 
three years of units granted under this plan are as follows:

Units granted under the Performance Unit Plan are subject to a five-year vesting schedule. The most recent 
units granted under this plan are as follows: 

Grant Date

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 years ended December 31, 2016, 2015, and 2014, MGE recorded $3.1 million, $1.0 million, and 
$2.0 million, respectively, in compensation expense as a result of awards under the plans. In January 2016, 
cash payments of $1.2 million were distributed relating to awards that were granted in 2011. During the year 
ended December 31, 2015, MGE recorded a $0.2 million gain on 4,676 units forfeited. No forfeitures 
occurred during the years ended December 31, 2016 and 2014. At December 31, 2016, $6.9 million of 
outstanding awards are vested, and of this amount, no cash settlements have occurred.

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. 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. MGE's financial commodity 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.

c.  Financial Statement Presentation. 

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 electricity 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 offset with a corresponding 
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, 2016, the fair value of exchange traded derivatives and FTRs exceeded 
their cost basis by $1.3 million. At December 31, 2015, the cost basis of exchange traded derivatives and 
FTRs exceeded their fair value by $0.8 million. 

MGE is a party to a 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 sheets. 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, 2016 
and 2015, reflects a loss position of $50.6 million and $53.3 million, respectively. The actual cost will be 
recognized in purchased power expense in the month of purchase.

MGE's commodity derivative contracts, FTRs, and 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 sheets 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 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, 
2016, no collateral is required to be, or 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, 2016, no counterparties were in a net liability position. As of December 31, 2015, certain 
counterparties were in a net liability of less than $0.1 million.  

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, 2016, no counterparties have defaulted. 

16.  Rate Matters - MGE Energy and MGE. 

a.  Rate Proceedings. 

On December 15, 2016, the PSCW authorized MGE to decrease 2017 rates for retail electric customers 
by 0.8% or $3.3 million and to increase rates for retail gas customers by 1.9% or $3.1 million. The 
decrease in retail electric rates is attributable to declining fuel and purchased power costs. The increase in 
retail gas rates covers costs associated with MGE's natural gas system infrastructure improvements. The 
authorized return on common stock equity for 2017 is 9.8% on 57.2% common equity. The PSCW also 
approved MGE's request to extend the current accounting treatment for transmission related costs 
through 2018. 

In July 2015, the PSCW approved MGE's request to extend the current accounting treatment for 
transmission related costs through 2016, conditioned upon MGE not filing a base rate case for 2016. This 
accounting treatment allows MGE to reflect any differential between transmission costs reflected in rates 
and actual costs incurred in its next rate case filing. 

91 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
On December 23, 2014, the PSCW authorized MGE to increase 2015 rates for retail electric customers 
by 3.8% or $15.4 million and to decrease gas rates by 2.0% or $3.8 million. The increase in retail electric 
rates cover costs associated with the construction of emission-reduction equipment at Columbia, 
improvements and reliability of the state's electric transmission system, fuel and purchased power related 
to coal delivery costs, partially offset by lower cost as a result of market conditions for pension and 
postretirement benefit costs. The authorized return on common stock equity was 10.2%. 

The PSCW also approved changes to customer rates and rate design for gas service that became effective 
January 1, 2015. Gas rate design consists of a fixed monthly customer charge and a variable charge tied 
to actual usage, in addition to the separate charge through the PGA for natural gas commodity costs. The 
change shifted more of the rate recovery to the monthly charge, reflecting the related fixed costs of 
providing gas services, and reduced the variable usage-based charge. Thus, gas net income is expected to 
be more evenly distributed during the year and less sensitive to weather. 

On July 26, 2013, the PSCW authorized MGE to freeze electric and natural gas rates at 2013 levels for 
2014. The order authorized 100% AFUDC on the Columbia scrubber construction project and deferral of 
increased costs related to ATC and MISO network upgrade fees. As part of the rate freeze plan 
authorized by the PSCW, effective January 1, 2014, approximately $6.3 million associated with a 2012 
fuel rule surplus credit was amortized in 2014. The fuel credit accrued interest at MGE's weighted cost of 
capital. The authorized return on common stock equity was unchanged at 10.3%. 

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 annual fuel proceedings. 
Any over/under recovery of the actual costs in a year is determined in the following year and is then 
reflected 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 exceeded 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 were less than 98% of the electric fuel costs allowed in that order. 

In August 2015, the PSCW approved a $0.00256/kWh fuel credit that began on September 1, 2015, and 
continued throughout 2016. The fuel credit established a mechanism to return $10.9 million of fuel 
savings to electric customers as a bill credit. MGE returned $2.6 million of electric fuel-related savings to 
customers through bill credits during the period from September 1, 2015, through December 31, 2015. 
MGE returned $8.3 million of electric fuel-related savings during the year ended December 31, 2016.  

In January 2016, the PSCW lowered MGE's 2016 fuel rules monitored costs by $14.8 million as a result 
of continued lower projected fuel costs in 2016. Also, in March 2016, MGE filed its 2015 fuel plan 
reconciliation application showing an overcollection of 2015 fuel rules monitored costs. In July 2016, the 
PSCW issued a final order stating that MGE shall refund the additional fuel savings incurred during 2015 
and 2016 for a total of $15.7 million to its retail electric customers over a one-month period. In 
September 2016, MGE returned $15.5 million to customers through bill credits. 

As of December 31, 2016, MGE has deferred $5.6 million of 2016 fuel savings that were in excess of the 
fuel savings included within the fuel credits referenced above. These costs will be subject to the PSCW's 
annual review of 2016 fuel costs, expected to be completed in 2017.

(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 is 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. Management expects to recover these costs in future customer rates. 

(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 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. 
Management expects to recover these costs in future customer rates. 

b.  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, 2016, under agreements classified as operating leases 
with noncancelable terms in excess of one year are as follows:

c.  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 issued by the WDNR to ensure compliance with these discharge limits. Permits are subject to 
periodic renewal. 

EPA's Effluent Limitations Guidelines (ELG) and Standards for Steam Electric Power Generating Point 
Source Category 
In November 2015, the EPA published its final rule setting Effluent Limitations Guidelines (ELG) for 
the steam electric power generating industry. The ELG rule establishes federal limits on the amount of 
metals and other pollutants that can be discharged in wastewater from new and existing steam electric 
generation plants. The ELG rule mostly covers pollutants that are captured by certain air pollution 
control systems and via wet ash handling systems at coal-burning power plants with units greater than 
50 MW generation capacity. The operators of our Columbia and Elm Road Units have indicated that 
equipment upgrades may be necessary to comply with the new discharge standards. The rule will be 
applied to Wisconsin-based power plants as they renew their WPDES permits, beginning in 2018 but no 
later than 2023. Management believes that any compliance costs will be recovered in future rates based 
on previous treatment of environmental compliance projects. 

EPA Cooling Water Intake Rules (Section 316(b)) 
Section 316(b) of the Clean Water Act requires that the cooling water intake structures at electric power 
plants meet best available technology standards so that mortality from entrainment (drawing aquatic life 
into a plant's cooling system) and impingement (trapping aquatic life on screens) are reduced. The EPA 
finalized its 316(b) rule for existing facilities in 2014. Section 316(b) requirements are implemented in 
Wisconsin through modifications to plants' WPDES permits, which govern plant wastewater discharges. 
The WDNR is currently developing guidance and rules to implement the EPA 316(b) rule.  

Our WCCF, Blount, and Columbia plants are considered existing plants under this rule. Our WCCF 
facility already employs a system that meets the 316(b) rule. Our Blount plant has conducted historical 
studies that will show that it will likely be in compliance with this rule when its WPDES permit is 
renewed in 2017. The operator of our Columbia plant is conducting an intake study to demonstrate 
compliance with the 316(b) rule and/or identify design criteria needed to meet the new rule requirements 
prior to Columbia's 2017 WPDES permit renewal. The exact requirements at Blount and Columbia, 
however, will not be known until the WDNR finalizes its rule, approves the plant operators' approach, 
and those sites' WPDES permits are modified to account for this rule. Nonetheless, MGE expects that the 
316(b) rule will not have material effects on its existing plants. 

Energy Efficiency and Renewables 

The Wisconsin Energy Efficiency and Renewables Act requires that 10% of the state's electricity be 
generated from renewable sources. MGE is in compliance with the 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 various emissions including emissions of 
particulate matter (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. Current EPA initiatives under the Clean Air Act, including a recent update to the 
Cross-State Air Pollution Rule (CSAPR), and recently revised National Ambient Air Quality Standards 
(NAAQS) for ozone have the potential to result in additional operating and capital expenditure costs for 
MGE. 

94 

  
 
 
 
 
 
 
 
 
 
 
 
EPA's Greenhouse Gas (GHG) Reduction Guidelines under the Clean Air Act 111(d) Rule 
In October 2015, the EPA finalized its Clean Power Plan (CPP) rule with an effective date of 
December 2015, setting guidelines and approval criteria for states to use in developing plans to control 
GHG emissions from existing fossil fuel-fired electric generating units (EGUs) and systems. 
Implementation of the rule is expected to have a direct impact on existing coal and natural gas fired 
generating units, including possible changes in dispatch and additional operating costs. 

In October 2015, many states (including Wisconsin) and other litigants filed petitions with the U.S. Court 
of Appeals for the District of Columbia Circuit asking for a stay of the CPP rule, and seeking expedited 
review of the petitioners' challenges to the CPP's legality. The parties' request to stay the rule was denied 
by the D.C. Circuit on January 20, 2016, but the D.C. Circuit issued an expedited schedule for resolving 
the merits of the litigation. On January 26, 2016, several parties filed a request for a stay of the CPP with 
the U.S. Supreme Court. 

On February 9, 2016, the U.S. Supreme Court issued a stay blocking implementation of the CPP pending 
the Court's own review. The CPP may not be implemented until the Supreme Court lifts the stay, 
presumably after the courts ultimately resolve the underlying legality of the rule. Oral arguments were 
held before the D.C. Circuit in September 2016 and a decision by the D.C. Circuit is expected in 2017. 

Given the pending legal proceedings, the nature and timing of any final requirements is subject to 
uncertainty. If the rule remains substantially in its present form, it is expected to have a material impact 
on MGE. 

National Ambient Air Quality Standards (NAAQS) and Related Rules 
The EPA's NAAQS regulations have been developed to set ambient levels of six pollutants to protect 
sensitive human populations (primary NAAQS) and the environment (secondary NAAQS) from the 
negative effects of exposure to these pollutants at higher levels. The Clean Air Act requires that the EPA 
periodically review, and adjust as necessary, the NAAQS for these six air pollutants. The EPA's NAAQS 
review can result in a lowering of the allowed ambient levels of a pollutant, a change in how the pollutant 
is monitored, and/or a change in which sources of that pollutant are regulated. States implement any 
necessary monitoring and measurement changes and recommend areas for attainment (meets the ambient 
requirements) or nonattainment (does not meet these standards). The EPA makes the final attainment and 
nonattainment determinations. States must come up with a state implementation plan (SIP) to get 
nonattainment areas into attainment and maintain air quality in attainment areas. A company with 
facilities located in a nonattainment area will be most affected. Their facilities may be subject to 
additional data submissions and measurement during permitting renewals, their facilities may need to 
meet new emission limitations set by the SIP (which could result in significant capital expenditures), and 
the company may have additional expenses and/or difficulties expanding existing facilities or building 
new facilities. The process from determining acceptable primary and/or secondary NAAQS to executing 
SIPs can take years. Nonetheless, because the NAAQS regulations have the potential to affect both 
existing and new facilities in areas, MGE continuously monitors changes to these rules to evaluate 
whether changes could impact our operations. In addition, the EPA has adopted interstate transport rules 
such as the CSAPR to address contributions to NAAQS nonattainment from upwind sources in 
neighboring states. In the following paragraphs we discuss specific NAAQS and transport rule 
developments that may affect MGE. 

Ozone NAAQS 
In October 2015, the EPA revised the primary and secondary ozone NAAQS, lowering each to 70 ppb. 
The rule became effective in December 2015. In November 2016, the EPA introduced a proposed 
implementation rule for the revised standard. Based on current ozone monitoring data, it appears that 
Milwaukee County (where our Elm Road Units are located) will likely not attain the lowered standards, 
and Dane and Columbia Counties (where our WCCF/Blount and Columbia Units are located, 
respectively) may attain them. Final attainment designations for these three counties will be based upon 
air monitoring data for years 2014-2016. The EPA will finalize the designations by October 1, 2017 
based on that data. Once these EPA designations are complete, the State of Wisconsin will need to 
develop implementation plans for each county designated as nonattainment, which could affect 
operations and emission control obligations for plants located within the nonattainment counties.  

95 

  
 
 
 
 
 
 
 
 
 
The State of Wisconsin has joined a lawsuit filed by several states challenging the EPA's new ozone 
standard, alleging that the new standard is not attainable and the EPA is not properly considering 
background levels in setting its ozone attainment levels. Oral arguments in this case are scheduled to 
begin in April 2017. MGE will continue to monitor the EPA's progress on attainment designations and 
related litigation to assess potential impacts at our facilities, particularly our Elm Road Units. 

Sulfur Dioxide (SO2) NAAQS 
In March 2015, the EPA identified MGE's Columbia Plant in Columbia County as a large stationary 
source of SO2 that may exceed the one hour SO2 NAAQS standard and was subject to a State of 
Wisconsin proposed county attainment/nonattainment determination. In September 2015, Wisconsin sent 
a letter to the EPA proposing that Columbia County be designated as being in attainment for the SO2 
NAAQS based on recent modeling demonstrating that SO2 pollution controls on the Columbia Plant had 
brought the county into attainment. In June 2016, the EPA issued a final rule classifying Columbia 
County as an unclassified/attainment area. MGE does not anticipate any material costs from this rule. 

Nitrogen Dioxide (NO2) NAAQS 
The WDNR has revised its state rules to incorporate the EPA's one hour NO2 NAAQS rule that was 
finalized in 2010. The effective date of the state rule was August 1, 2016. The WDNR is currently 
seeking input from the public on ideas for implementing this one-hour standard. Wisconsin's NO2 
NAAQS rule will affect our stationary fossil-fuel generation sources by requiring that we demonstrate 
consistency with the NAAQS when applying for certain air permits. Sources that cannot demonstrate 
compliance with the NAAQS may be required to install emission controls or restrict operations. MGE 
will continue to monitor developments while the WDNR implements guidance for compliance with the 
one-hour NAAQS. 

EPA's Cross-State Air Pollution Rule: Proposed Ozone Season Update based on 2008 Ozone NAAQS 
The EPA's Cross-State Air Pollution Rule (CSAPR) is an interstate air pollution transport rule designed 
to reduce ozone and fine particulate (PM2.5) air levels in areas that the EPA has determined are being 
affected by pollution from neighboring and upwind states. This is accomplished in the CSAPR through a 
reduction in SO2 and NOx from qualifying fossil-fuel fired power plants in upwind or "contributing" 
states. NOx and SO2 contribute to fine particulate pollution, and NOx contributes to ozone formation. 
Reductions are achieved through a cap and trade system. Individual plants can meet their caps through 
modifications and/or buying allowances on the market. 

In October 2016, the EPA finalized rulemaking for an update to CSAPR that incorporated 2008 Ozone 
NAAQS levels into the rule (the original CSAPR is based on 1997 Ozone NAAQS levels). The update 
affects 22 states, including Wisconsin, by further limiting statewide NOx allowances in each of those 
states. The rule also includes revisions to CSAPR that are designed to address issues remaining from the 
D.C. Circuit remand of CSAPR, including Wisconsin's inclusion in the NOx ozone season portion of the 
rule. The State of Wisconsin filed a legal challenge to the CSAPR update rule asserting, among other 
things, that the rule over-controls NOx emissions in Wisconsin.  

The CSAPR Update rule will further reduce summertime (or Ozone Season) NOx emissions allocations 
from power plants starting in 2017. MGE intends to meet the rule requirements through a combination of 
owned, received, and purchased. Depending on the number of allocations MGE receives for ozone 
season, the number of allocations that MGE must purchase, and the cost of allocations, this requirement 
could be material for MGE. 

Clean Air Visibility Rule (CAVR) 
Columbia is subject to the best available retrofit technology (BART) regulations, a subsection of the 
EPA's Clean Air Visibility Rule (CAVR), which may require pollution control retrofits. Columbia's 
existing pollution control upgrades, and the EPA's stance that compliance with the CSAPR equals 
compliance with BART, should mean that Columbia will not need to do additional work to meet BART 
requirements. At this time, however, the BART regulatory obligations, compliance strategies, and costs 
remain uncertain due to the continued legal challenges surrounding CSAPR and CAVR. 

96 

  
 
 
 
 
 
 
 
 
 
In December 2016, the EPA introduced a final rule (posted online but not yet scheduled for publication 
in the Federal Register) extending state implementation plan deadlines by three years from 2018 to 2021 
for the next implementation phase of the CAVR, which goes beyond BART and may affect utilities. This 
extension would allow for states to coordinate their CAVR compliance with other compliance efforts, 
which should lessen the burden to comply. It is too early to determine if the rule will affect MGE. MGE 
will continue to monitor developments. 

Solid Waste 

EPA's Coal Combustion Residuals Rule 
In December 2014, the EPA finalized its Disposal of Coal Combustion Residuals from Electric Utilities 
(CCR) rule. The rule became effective in October 2015. It provides that coal ash will be regulated as a 
solid waste, and defines what ash use activities would be considered generally exempt beneficial reuse of 
coal ash. The rule also regulates landfills, ash ponds, and other surface impoundments for coal 
combustion residuals by regulating their design, location, monitoring, and operation. This portion of the 
rule is accomplished in phases to allow for sites with onsite storage and/or disposal to evaluate their 
compliance with the rule's design criteria. Landfills and impoundments that cannot meet design criteria 
will need to close formally within defined timeframes. 

The Columbia and Elm Road Units co-owners and plant operators are working through the phased 
requirements to plan and implement changes necessary at those facilities to meet design criteria. Review 
of our Elm Road Units has indicated that the costs to comply with this rule are not expected to be 
significant. Columbia's operator has developed a preliminary implementation schedule for meeting the 
various deadlines spelled out in the rule. Costs at Columbia will be dependent on what is determined 
during the evaluation stage. Management believes compliance costs will be recovered in future rates 
based on previous treatment of environmental compliance projects. 

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 Clean Air Act Litigation 
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 the co-owners, 
including MGE. The NOV alleged that WPL, which is the plant operator, 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 June 2013, the court approved and entered a 
consent decree entered by the EPA, Sierra Club, and the co-owners of Columbia. One of the 
requirements of the consent decree requires installation of an SCR system at Columbia Unit 2 by 
December 31, 2018. Installation of the SCR has been approved by the PSCW and is currently under 
construction. MGE's share of the projected cost for the SCR system is estimated to be $22-$24 million, 
with expected completion in 2018.  

d.  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. 
MGE does not expect the resolution of these matters to have a material adverse effect on its consolidated 
results of operations, financial condition, or cash flows. 

e.  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 $11.4 million in capital 
for such infusions. The timing of these infusions is dependent on the needs of the investee and is 
therefore uncertain at this time. 

97 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
In addition, MGE Energy has a three year agreement with a venture debt fund expiring in 
December 2019. MGE Energy has committed to invest up to a total of $1.5 million into this fund. As of 
December 31, 2016, MGE Energy has $0.4 million remaining in commitments. The timing of infusions is 
dependent on the needs of the fund and is therefore uncertain at this time. 

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

18.  Asset Retirement Obligations - MGE Energy and MGE. 

  Thereafter   
5,646   

440  $ 

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 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, 2016, 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 summarizes the change in AROs. Amounts include conditional AROs.

An additional $1.3 million was recorded in the fourth quarter, associated with this ARO, based on 
revised estimates. 

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

and MGE. 

a.  Revenue from Contracts with Customers. 

In May 2014, the FASB issued authoritative guidance within the Codification's Revenue Recognition 
topic that provides guidance on the recognition, measurement, and disclosure of revenue from contracts 
with customers. The new standard establishes a five step model for recognizing and measuring revenue 
from contracts with customers and replaces existing guidance on revenue recognition. The objective of 
the new standard is to provide a single, comprehensive revenue recognition model for all contracts with 
customers to improve comparability within industries, across industries and across capital markets. The 
underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to 
customers at an amount that the entity expects to be entitled to in exchange for those goods or services. 

98 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
MGE Energy and MGE have been assessing the impact of this guidance on revenue streams within the 
scope of the new standard. All retail electric and gas revenues are tariff rates approved by the PSCW. 
Based on our evaluation of the new standard, retail revenues will be recognized within the period in 
which utility service is provided to the customer and the performance obligation is fulfilled, consistent 
with our current revenue recognition model. Electric revenues for sales to the market represent wholesale 
sales made to third parties who are not ultimate users of the electricity. These sales may also include 
bilateral sales to other utilities or power marketers. Revenues for sales to the market will be recognized 
when the sale is completed within the market operated by MISO, similar to the recognition under our 
current revenue recognition model. In addition, revenues from the transportation of gas will continue to 
be recognized upon the performance of services for the respective customer. Based on our assessment of 
the new standard, revenue recognition for retail revenues, sales to the market, and transportation of gas 
will be consistent with our current revenue recognition model. However, additional disclosures regarding 
the nature, amount, timing, and uncertainty of these revenue streams and related cash flows arising from 
contracts with customers will be required as a result of the new standard. 

The Power and Utilities Task Force of the AICPA is formulating a utility industry-specific interpretation 
of the guidance regarding the collectability threshold of probable within the new standard. The 
collectability criterion could impact the timing of revenue recognition for uncollectible accounts. The 
Power and Utilities Task Force of the AICPA is also requesting the FASB issue an industry-specific 
clarification regarding the accounting treatment of upfront contributions in the aid of construction, also 
known as CIAC. The final clarification on this topic could result in a material impact on the consolidated 
financial statements. Management continues to analyze newly-released interpretative guidance and assess 
the related impacts to the current revenue recognition model.  

This authoritative guidance will become effective January 1, 2018, and MGE Energy and MGE 
anticipate adopting the standard upon the effective date. Adoption of this standard is permitted under one 
of two methods: the full retrospective method or the modified retrospective method. MGE Energy and 
MGE are continuing to assess the permitted implementation methods and the impact on our financial 
statements. 

b.  Consolidation. 

In February 2015, the FASB issued authoritative guidance within the Codification's Consolidation topic 
that provides guidance on the evaluation of certain legal entities for consolidation purposes. This 
authoritative guidance became effective January 1, 2016. This guidance had no impact on our financial 
statements. 

c.  Debt Issuance Costs. 

In April 2015, the FASB issued authoritative guidance within the Codification's Interest topic that 
provides guidance on the presentation of debt issuance costs in financial statements. This authoritative 
guidance became effective January 1, 2016, and changed the presentation of debt issuance costs on the 
balance sheet. Prior to the authoritative guidance, debt issuance costs were treated as a deferred asset, and 
beginning January 1, 2016, these costs are included as a direct deduction to the related debt liability on 
the consolidated balance sheets. As of December 31, 2016, assets (other deferred assets and other) and 
liabilities (long-term debt) decreased approximately $3.9 million as a cumulative result of the guidance. 
In addition, this guidance was applied retrospectively to all prior periods presented, resulting in a 
decrease to assets and liabilities of $4.3 million for the year ended December 31, 2015. 

d.  Financial Instruments. 

In January 2016, the FASB issued authoritative guidance within the Codification's Financial Instruments 
topic that provides guidance on the recognition and measurement of financial instruments. This 
authoritative guidance will become effective January 1, 2018, and will require equity investments to be 
measured at fair value with changes in fair value recognized in net income rather than in other 
comprehensive income. As a result of this guidance, MGE Energy and MGE will no longer have any 
other comprehensive income. This standard will be applied using a modified retrospective approach, with 
a cumulative effect adjustment recorded to opening retained earnings as of the beginning of all prior 
periods presented. 

99 

  
 
 
 
 
 
 
 
 
 
 
 
e.  Leases. 

In February 2016, the FASB issued authoritative guidance within the Codification's Leases topic that 
provides guidance on the classification, recognition, measurement, and disclosure of leases. The new 
leasing standard establishes that a lease conveys the right to control the use of identified property, plant, 
or equipment for a period of time in exchange for consideration. Under the new guidance, lessees will be 
required to recognize all leases with terms greater than one year, including operating leases, on the 
consolidated balance sheet by recording a right-of-use asset and lease liability. Prior to the authoritative 
guidance, only capital leases were recognized on the balance sheet by lessees. The new accounting 
guidance as applied by lessors is materially consistent from that applied under current GAAP.  

Management has begun utilizing a bottoms-up approach to analyze the impact of the standard on our 
lease portfolio. MGE Energy and MGE have been reviewing current accounting policies and procedures 
to identify potential differences in accounting treatment that would result from applying the requirements 
of the new standard to our existing lease portfolio. In addition, we are identifying appropriate changes to 
our business processes, systems, and controls to support recognition and disclosure requirements under 
the new standard. This authoritative guidance will become effective January 1, 2019, with early adoption 
permitted. The new leasing standard requires entities to recognize and measure leases at the beginning of 
the earliest comparative period presented using a modified retrospective approach. MGE Energy and 
MGE are currently assessing the impact this pronouncement will have on our financial statements. 

f.  Restricted Cash. 

In November 2016, the FASB issued authoritative guidance within the Codification's Statement of Cash 
Flows topic that provides guidance on the classification and presentation of changes in restricted cash 
within the statement of cash flows. The new standard was issued to eliminate a current diversity in 
practice for the accounting treatment of restricted cash. Under the new guidance, reporting entities will 
be required to explain the changes in the total of restricted and unrestricted cash and cash equivalents 
when reconciling the beginning and ending balances on the statement of cash flows. Prior to the 
authoritative guidance, changes in restricted cash were presented as either cash flows from operating, 
investing, or financing activities within the statement of cash flows, as appropriate based on the nature of 
the restriction. Also under the new standard, reporting entities will be required to provide a reconciliation 
from the balance sheet to the statement of cash flows and disclose the nature of the restrictions of cash. 
This authoritative guidance will become effective January 1, 2018. Upon the effective date, MGE Energy 
and MGE will change the presentation of restricted cash to reflect this change in accounting guidance. 
MGE Energy and MGE will also retrospectively apply the guidance to all prior periods presented. As of 
December 31, 2016, MGE Energy and MGE had $5.1 million of restricted cash classified within other 
current assets on the consolidated balance sheets.

Segment Information - MGE Energy and MGE. 

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

The nonregulated energy operations are conducted through MGE Energy's subsidiaries: MGE Power, MGE 
Power Elm Road, and MGE Power West Campus. These subsidiaries 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 and MGEE Transco, in ATC Holdco, a company 
formed to pursue electric transmission development and investments outside of Wisconsin. See Footnote 4 for 
further discussion. 

The "All Others" segment includes: corporate, CWDC, MAGAEL, MGE State Energy Services, MGE 
Services, and NGV Fueling Services. 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. 

The following table shows segment information for MGE Energy's and MGE's operations:

MGE Energy and MGE 

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures 

During the fourth quarter of 2016, 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, 2016, 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, 2016, 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, 2016. As a result of that assessment, management determined that there 
were no material weaknesses as of December 31, 2016 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 members 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.

Condensed Parent Company Financial Statements (continued) 
Notes to Condensed Financial Statements 
(Parent Company Only) 

1. 

Basis of Presentation. 

MGE Energy is a holding company and conducts substantially all of its business operations through its 
subsidiaries. For Parent Company only presentation, investment in subsidiaries are accounted for using the 
equity method. These condensed Parent Company financial statements and related notes have been prepared 
in accordance with Rule 12-04, Schedule I of Regulation S-X. These statements should be read in 
conjunction with the financial statements and the notes in Item 8. Financial Statements and Supplementary 
Data of the Annual Report on Form 10-K for the year ended December 31, 2016. 

2.

bank commitments of $50.0 million. At December 31, 2016, no borrowings were outstanding under this 
facility. 

See Footnote 10 of the Notes to Consolidated Financial Statements for further information regarding

(a)  Excludes $15.8 million dividend in kind to MGE Energy from 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, above the PSCW 
authorized amount of $43 million, 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, 2016, is 60.2% as determined under the calculation used in the rate proceeding. 
MGE was not restricted from paying cash dividends in 2016. Cash dividends of $50.0 million and 
$30.0 million were paid by MGE to MGE Energy in 2016 and 2015, respectively. In 2016, MGE also 
transferred its ownership interest in MGE Transco to MGE Energy in the form of a dividend in kind of 
$15.8 million. 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, 2016, approximately $338.5 million was available for the payment 
of dividends under this covenant. 

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