Beyond the expected.
A
t Alliant Energy, our stewardship is nothing new. Investments in clean energy and the
use of hydroelectric and wind generation have been central to our strategy for decades.
Working with our customers to find efficiencies is common to the way we do business.
Employee giving of time and talent is visible throughout the areas we live and work.
What is new and exciting are the creative ways our employees, customers and communities
are pushing beyond traditional approaches to provide for a better tomorrow. This can be seen
in the transformation of a retired landfill into a vibrant solar energy garden, or the restoration
of milkweed habitat to save Monarch butterflies. The innovation is truly remarkable.
Creative collaboration with the Electric Power Research Institute inspired our solar learning
laboratory. This 1,300-solar-panel installation is located at our corporate campus in Madison,
Wisconsin. Understanding how to optimize solar technology in our Midwest climate will
help us provide more energy solutions for our customers. The project also includes a battery
storage system and electric vehicle charging stations.
A fresh perspective led to the creation of our Alliant Energy Advisor. This online tool delivers
energy-saving actions based on behavioral motivations. An individualized approach helps our
customers overcome common barriers to pursuing energy efficiency. This effort proved so
successful it was recognized by the Midwest Energy Efficiency Alliance.
These are just a few of the achievements you will find in our report. I hope you enjoy learning
about the many ways Alliant Energy is continuing our stewardship. These accomplishments
are only possible through the joint efforts of our company and those we serve – taking a new
approach and going beyond the expected.

Water and wind power
are key clean energy sources
Emission-free energy is nothing new to Alliant Energy.
We’ve been tapping water power for over a century with
our Prairie du Sac and Kilbourn hydroelectric dams on
the Wisconsin River. And we’ve been purchasing wind
power for nearly 20 years. Our first owned and operated
wind farm went into operation in 2008. Currently, Alliant
Energy has four wind farms with 344 wind turbines,
across Iowa, Minnesota and Wisconsin.
Benefits of natural gas generation
Natural gas generation brings both environmental and economic development benefits. Natural gas emits
about half the carbon, approximately two-thirds less nitrogen and about 99% less sulfur than coal, which
means cleaner air and a healthier environment.
Both the nearly completed Marshalltown Generating Station and the soon-to-be-started Riverside Energy
Center expansion are examples of how we are modernizing generation. The Marshalltown facility is
near our former coal-fired Sutherland Generating Station. Riverside is on a large property that formerly
included our coal-fired Rock River Generating Station.
The construction of natural gas facilities in Marshalltown, Iowa, and Beloit, Wisconsin, creates a
multi-year boost to the local communities with hundreds of construction jobs. Once the facilities are
completed, we’ll be adding more than 50 new permanent positions.

Using technology to improve the air quality
Alliant Energy has nearly completed construction to improve the environmental profile of our largest
coal-fired facilities.
We and our co-owners began work on another air quality improvement project at Columbia Energy
Center Unit 2 near Portage, Wisconsin, in the spring of 2016. When it’s finished in two years, we
expect to further reduce nitrogen oxides by 50%.
At Edgewater Generating Station Unit 5 in Sheboygan, Wisconsin, we completed the installation
of air quality improvement technology in 2016 to reduce sulfur dioxide by 90%. This project is also
decreasing mercury and particulate matter.
Next year, we plan to break ground at the Ottumwa Generating Station in Ottumwa, Iowa, on a
project to reduce nitrogen oxides by 50%. The construction is expected to be completed in 2019.
At four recently completed large
environmental improvement projects,
we recycled more than

Recycling is part of the plan
The construction of our large environmental improvement
projects requires a lot of material. That’s why we
integrate construction waste recycling into our planning
and day-to-day building process. For each project, we
are recycling at least 70% of the metal, wood, concrete,
asphalt and cardboard. We also recycle other building
byproducts.

Solar technology study providing customer benefit
Alliant Energy is collaborating with the Electric Power Research Institute (EPRI) on a three-year solar performance
study. Together, we are measuring how solar technology performs in a Midwest climate.
We have installed more than 1,300 solar panels on several types of building- and ground-mounted structures at our
Madison, Wisconsin, office. The installation also includes an energy battery storage system and electric vehicle
charging stations available to both employees and the public. The project was completed in spring 2016.
EPRI is collecting and analyzing the data. It will be shared on a web-based dashboard available to the public at
alliantenergy.com/solar. Public walking trails with informational signs allow visitors to view many of the solar
structures. We also conduct regular educational tours of the site.
Landfill property to generate
clean energy
An Alliant Energy coal ash landfill near Beloit,
Wisconsin, is now home to a 2.3-megawatt solar field
providing clean energy to customers. The Rock River
Solar Facility was completed in 2016 through a unique
design and building process, enabling it to be built on
top of a retired landfill.
The landfill has an engineered cover buried two feet
below the surface that cannot be breached. This meant
the typical solution of driving beams into the ground to
support the solar structure was not an option. Working
with the Wisconsin Department of Natural Resources,
we landed on a design that used precast concrete pads
for the solar facility to sit on top of the landfill without
disturbing what’s buried below. Hanwha Q CELLS USA
owns and operates the Rock River Solar Facility. Alliant
Energy has a 10-year agreement to purchase power.

Improving the waters of Lake Wisconsin
We have collaborated with the Wisconsin Department of Natural Resources and the River Alliance of Wisconsin
since 2014 to provide grants from Alliant Energy’s Prairie du Sac Dam Aquatic Resources Enhancement Fund. Up to
$50,000 annually is available to government, conservation and water management groups to fund projects targeted
at improving the waters of the Lake Wisconsin basin.
A grant was provided to the Lake Wisconsin Alliance to conduct nearshore fishery surveys on Lake Wisconsin
in 2015 and 2016. Nearshore fish populations are important because they often reveal lake-ecosystem
stresses before traditional measurements detect water quality problems. More information is available at
alliantenergy.com/lakewisgrants.
Helping the Karner Blue and Monarch butterflies
The Karner Blue butterfly is an endangered species that only feeds
on wild lupine. The number of Monarch butterflies has decreased
significantly due to the drastic decline of its sole food source,
milkweed.

Fueling the Future
Our work to deliver natural gas to Iowa and
Wisconsin is grounded in safety.
To maintain safety and reliability, we are
identifying existing pipelines that will need
enhanced inspection and verification. We are also
increasing our ability to use computers to remotely
monitor the gas system, part of the SCADA
system.
Strengthening our power grid
Our customers want a safe, reliable electric delivery
system that is robust, resilient and responsive to their
needs. To accomplish this, we have a target to replace
1.5% of our electric system annually.
We are replacing aging pipelines across the
territory. Between 2017-2020, our Fueling the
Future program will replace around 250 miles of
transmission pipeline in Iowa.
That’s why we are building our future energy grid on
these four pillars:

A responsive power
grid with pricing
options balances
different types of
usage. It’s also built to
seamlessly incorporate
emerging technologies,
like solar.
A robust power grid
stands up better
to storms and the
environment. It features
more underground
power lines and bigger
poles for overhead
lines.
A resilient power grid
recovers quickly from
events and features
remote-controlled
switches and other
equipment, commonly
called SCADA. It’s
supported by
experienced technical
professionals who
respond quickly and
work efficiently.
A reliable power grid

Directional drilling reduces environmental impacts
Our company is investing significant resources to
develop and expand natural gas service to unserved and
underserved communities. This initiative helps unlock
economic development opportunities for communities
while also delivering cost-effective, reliable and cleanburning fuel to customers.
In 2015, we used HDD to minimize land disturbance and
avoid wetland impacts for over 70 miles of new natural
gas pipeline installations. Compared to digging trenches,
this prevented temporary impacts to wetlands of roughly
176 acres for these installations. That’s the equivalent of
160 American football fields.
Horizontal directional drilling (HDD) is a steerable
method of installing underground pipe, which allows us
to put in the pipe without digging a trench. Instead, a
surface drilling rig creates a bore path along a shallow
arc that has minimal impact on the surrounding area.

We put our wallets, hearts and backs into supporting United Way
In 2015, our combined employee and corporate giving to United Way was $1.2 million. And we used
our energy for good in other ways, too. During United Way Days of Caring in Iowa and Wisconsin, our
employees and retirees gave their time and talents to help their communities because we are all stronger
when Alliant Energy gives back.
Judging by employee participation, it’s one of our most popular events. It’s fun and easy to join together
and help local organizations. Our employees form teams and fan out to tackle projects for community and
nonprofit agencies, from clearing brush to painting apartments to helping food pantries. Some projects are
indoors; some are outdoors. It’s the biggest volunteer event of the year for the United Way.
Fighting hunger

Helping families facing hunger is a primary focus of our
Foundation and corporate philanthropy. Since 2007, Feeding
America food banks in our service territory have received
over $2.25 million directly from proceeds of our Drive Out
Hunger Golf Classic event. It is one of our Foundation’s
signature events.
In 2015 the event raised $385,000 for local food banks.
Employees and retirees also lend their time and energy to
pantries across our service territory throughout the year. In
addition, we gave $77,000 to the Hawkeye Area community

Our workplace
Safety is our number one focus
Safety is a Core Value, and our first priority is that nobody gets hurt. All employees are responsible for their own safety and for
the safety of those around them. We expect everyone to intervene if they witness an unsafe act or condition.
We surveyed our employees in 2016 to get their input on a wide variety of topics. We encourage their feedback so we can make
Alliant Energy an even better place to work. When asked if “adequate measures are taken at my location to ensure employee
safety,” 92% responded favorably. When asked if “I feel comfortable approaching co-workers if they are not following safety
policies and procedures,” 88% had a favorable response.
Alliant Energy electric and
gas crews regularly train
to be safe. Pole climbing is
an integral part of pole-top
rescue drills. On average,
the crews can climb to the
top of a pole, rescue an
unconscious person and
lower them down the pole
in 2-3 minutes.

Faster and safer equipment inspections
We consistently inspect the interior of our rubber line
hoses for defects. The inspection is done by widening the
line hose opening with both hands, which requires extreme
grip strength, awkward postures and repetitive motion. On
days when employees inspect over 100 line hoses, there
can be significant fatigue in the hands and arms.
Jon Nietzel, Lead Corporate Safety
Specialist, created a line hose roller to do
the inspections. This new tool (shown at
right) makes the inspections faster and
safer for all employees, regardless of the
person’s size. What used to take some
employees over four minutes to do now
takes them 15 seconds. This tool was selected to compete
in the 2016 ErgoCup – the top competition for ergonomic
innovation.

Contractor safety review process reduces injuries
As we strive for zero injuries with our employees, we seek the same level of
performance among our contractors. We have many contractors working on our behalf
every day, replacing or repairing equipment and building new facilities.
In 2013, our company initiated a process to improve the efficiency of evaluating our contractor safety
performance by partnering with ISNetworld. This company provides a comprehensive screening process for our
on-site contractors that looks at key leading and lagging safety performance indicators. This supports selection
of contractors with a strong safety culture.
Wow, that was a “Good Catch”
When Alliant Energy employees “catch” a
co-worker doing something safe, we encourage
them to call attention to it. The
Good Catch program is a way
to recognize positive safety
behavior either on or off the job.
Employees can submit a Good Catch for themselves
(I Did it Safely) or when they observe someone else
(You Did it Safely).
As a result, the contractors we hire have better safety performance. Their average OSHA recordable rates have
improved 14% over the past three years. Since 2013, the number of subscribing contractors achieving a passing
grade has improved from 70% to 97%. To achieve a passing grade, contractors must provide detailed information
and statistics on their safety program.
Public safety outreach is
an important part of our
company’s efforts to improve
awareness of the inherent
hazards associated with
natural gas and electric
power lines.

Employee Resource Groups
mean mentoring and more
Our Employee Resource Groups (ERGs) have been
producing more and more exciting and successful
events in recent years. ERGs are an arm of the
Recruitment and Diversity Department. They provide
a “community” for employees with shared interests.
ERGs also provide employees with opportunities for
professional development, networking and community
involvement.
We currently have six ERGs: Emerging Professionals
Connection, Equality Alliance, Multicultural Network,
Sustainability Squad, Veterans Alliance and Women’s
Network. They provide programs throughout the year
for members and employees at large.
Employee Resource Groups: activities and outcomes
 T he Sustainability Squad campaigned to switch from plastic carryout containers to
cardboard containers and biodegradable plant-based plastic flatware at the Madison
office cafeteria in 2015, and they succeeded!
 A
team from the Multicultural Network, the Women’s Network and the Emerging
Professionals Connection sponsored a very popular “speed mentoring” session, where
participants had the chance to talk with executives about career development.
 T he Emerging Professionals Connection (EPC) and the Sustainability Squad have
taken members on tours of generation facilities and operations centers. The EPC even
arranges a “boot camp” so members can experience electrical and gas line technician
training.
 T he Equality Alliance has increased dialogue about issues facing LBGT employees
through panel discussions and workshops.
Veterans Alliance creates
strong relationships
About 10% of our workforce identifies as former
military. Many military jobs transfer directly (or very
closely) to careers at Alliant Energy. Additionally,
there are even more employees who have had a
direct family member in the service: grandparents,
parents or siblings. They feel a connection and want
to show their respect and appreciation to veterans and former military.
Our Veterans Alliance is a great example of an ERG that is building community
both inside and outside our company. The group’s goal is to inform employees
about veteran-related issues, while also encouraging veterans to seek
employment at Alliant Energy.

College student creativity drives
electric vehicle marketing
We want more drivers to consider buying electric vehicles
(EVs) as a way to decrease emissions. So, we turned to
business students at the University of Iowa, University of
Northern Iowa, Iowa State University, Luther College and
St. Ambrose University for help.
In April 2016, the University of Iowa’s Tippie College of Business chapter of the American Marketing
Association hosted Alliant Energy’s University Challenge Case Competition with teams from other Iowa
schools.
The teams developed marketing plans that examined barriers to entry (and to EV conversion), factors that
have motivated innovators and early adopters to purchase EVs, and strategies to expand the adoption of EVs
within the Alliant Energy service area.
A panel of judges, primarily from Alliant Energy,
studied the teams’ entries. Students later
presented their proposals, and cash awards
were given to the top three teams.
We are
considering using
the students’
ideas in our
future marketing
campaigns to
encourage EV use.

Greenhouse gas reporting
The EPA’s mandatory greenhouse gas (GHG) reporting
rule applies to electric utility generation and natural gas
distribution operations at Alliant Energy. Compliance
requires monitoring and reporting of emissions that
exceed threshold levels.
The primary greenhouse gases emitted from Alliant
Energy’s utility operations is CO2 from the combustion
of fossil fuels at its larger electric generating facilities.
These emissions are primarily measured with CEMS.

Total greenhouse gas emissions reported to EPA for 2015 were 24.1 million metric tons of CO2-equivalent (CO2e).
The CO2e is a measure used to compare the emissions from various greenhouse gases based on their Global Warming
Potential (GWP). The CO2e for a gas is derived by multiplying the mass of the gas by the associated GWP and is
determined as follows:
Total CO2e = Summation of million metric tons of a gas x GWP of the gas
Total CO2e = Carbon dioxide (CO2) x 1 + methane (CH4) x 25 + nitrous oxide (N2O) x 298
Total CO2e = CO2 (million metric tons) x 1 + CH4 (million metric tons) x 25 + N2O (million metric tons) x 298
Source: Annual EPA Mandatory GHG Report submission protocols issued in the Code of Federal Regulations (CFR) at 40 CFR Part 98. The CO2 emissions reported for EPA’s GHG program
are based on operational control and do not adjust for equity share of jointly owned electric generating units.

Note: Fossil fuel combustion CO2e emissions are calculated using EPA’s mandatory regulations under 40 CFR Part 98. The Scope 2 system emission rate has been calculated
using the Greenhouse Gas Protocol guidelines. The Scope 2 emission rate is adjusted for sales of 2015 renewable energy credits (RECs). Market purchase power and sold
wind RECs have been factored into CO2 emission rate using the Green-e 2015 residual emission rate factor for MRO. The residual emission rate factor is available at:
http://www.green-e.org/docs/energy/ResidualMix2015.pdf. The methane (CH4) and nitrous oxide (N2O) eGRID2012 factors were also used for total CO2e from market purchase
power and sold wind RECs. The eGRID2012 emission factors are available at: https://www.epa.gov/energy/egrid. Total CO2e was calculated with global warming potentials as
follows: CO2 = 1, CH4 = 25, N2O = 298.

Renewable energy resources
Our company has been able to meet and expects to exceed the RES future requirements through companyowned renewables and purchase power agreements, primarily from wind generation. Therefore, we are
able to sell renewable energy credits (RECs) on the renewable energy market. RECs represent proof that
1 MWh of electricity was generated from an eligible renewable energy resource (renewable electricity).
Alliant Energy is subject to Renewable Energy Standards (RES)
in the states within our service area. These standards establish
the amount of energy electric utilities must supply from
renewable resources.
These certificates can be sold and traded, giving the purchaser of the RECs claim to renewable energy.
The RECs held by Alliant Energy may be sold, including to buyers not located in the states served with
power from IPL or WPL. These REC sales benefit our customers because proceeds are then returned as a
credit to reduce the amount charged for the electricity they purchase.

Utility
Primary watersheds for Alliant Energy operations
include the Great Lakes and Upper Mississippi
River drainage basins of the United States. A
watershed is the area that drains to a common
waterway, such as a stream, lake, river, estuary,
wetland, aquifer or even the ocean. The primary
source of water to support operations at each of
our generation facilities is provided in the table
to the right. In addition, the company’s generating
stations may supplement water use with well
water and city water.
In 2015, the estimated total IPL and WPL water
use from base load utility generation operations
was 7.9 billion gallons, which is approximately
equivalent to 449 gallons/MWh.
We predominantly use water in order to make
steam and cool equipment. Much of this “noncontact” cooling water is pumped through the
generating station in closed-loop piping systems.
This allows the water to cool process equipment
without ever coming into direct contact with it.
Therefore, more than 95% of water is returned
as clean water that meets federal and state
regulations for freshwater quality.

Coal combustion
residuals management
Coal combustion residuals (CCR) are what remain after
the direct combustion of coal in generating stations.
Alliant Energy’s goal is to manage CCR safely and
responsibly in order to protect both the environment and
the public while assuring compliance with state and
federal regulations.
We work with state regulatory agencies to identify
approved beneficial uses for CCR. Material that cannot
be beneficially reused is placed in landfills that are
permitted and include engineering design and controls
that meet or exceed applicable requirements.
There are different types of CCR:
In 2015, we were able to beneficially use more than 450,000 tons of CCR in products, or about
63% of the overall CCR generated. The overall annual rate of reuse has decreased from 2014 due
to the scrubber solids created from recently installed SO2 air quality control systems.

Environmental compliance
Alliant Energy operates in compliance with environmental requirements. However, there are occasions when the
company has missed reporting deadlines, exceeded permit levels or otherwise violated regulations. These instances
of non-compliance can result in fines or penalties. An environmental Notice of Non-Compliance (NOC) is a formal
notice of non-compliance from a regulatory agency, including notices of violation (NOV). All notices are investigated
and corrective measures are implemented according to local, state and federal regulations.

NUMBER OF NOCS
In 2015, Alliant Energy was issued two NOCs due to
regulatory agency air inspection findings and one NOC
for not discontinuing a wastewater permit at a closed
facility. In addition, there was one NOV from the EPA
for alleged air permit violations at IPL coal-fired power
plants. Further information on this NOV is available at
the EPA’s enforcement website. Disclosure of the IPL
Consent Decree can be found in Alliant Energy’s filings
with the U.S. Securities and Exchange Commission.

LEED progress
Alliant Energy pursues Leadership in Energy and
Environmental Design (LEED ) certification for
many new building construction projects. The LEED
program was created by the U.S. Green Building
Council (USGBC). It is a nationally accepted
benchmark for the design, construction and operation
of high performance “green” buildings. LEED
promotes a whole-building approach to sustainability
by looking at five key areas: sustainable site
development, water savings, energy efficiency,
materials selection and indoor environmental quality.
Alliant Energy also retires renewable energy credits
for the company’s LEED facilities’ energy use.

Our performance
Energy efficiency
In 2015, Alliant Energy’s energy-efficiency programs resulted in additional savings of over 263,000 MWh of electricity and over 6.1 million
therms of natural gas. This includes estimated savings in Wisconsin through the Focus on Energy (FoE) program and actual savings from the
program in Iowa.
Since 2001, the energy savings for Wisconsin residential and some business programs became part of the consolidated FoE program. The
FoE program is managed and tracked separately by the state of Wisconsin. In Iowa, the program is operated directly by utility companies
under the oversight of regulatory agencies.
We achieved energy-efficiency savings above average in 2008-2009. This increase includes post-flood recovery construction and renovation
in Iowa, as well as incentives funded by the American Recovery and Reinvestment Act. Our annual program results remain steady overall.

System reliability
Alliant Energy is continually working to improve our system reliability; however, power outages do occur. The majority
are the result of weather-related events, trees and wildlife. As preventative measures, we conduct tree trimming near
our distribution lines and install animal guards on pole-top transformers. Other events such as digging, construction
or auto accidents can damage lines, poles or other equipment and cause service interruptions. An electrical overload
may also cause the equipment to fail. Regardless of the reason for an outage, Alliant Energy workers strive to restore
power as quickly, efficiently and safely as possible.

Community giving
Alliant Energy and its employees support the communities in which we live and work. These efforts take place
through a combination of foundation, corporate and employee giving and volunteerism.
The Alliant Energy Foundation focuses on three main areas: Helping Families, Education and the Environment. In
addition, the Foundation will match qualifying employee philanthropic gifts of $50 or more, up to $2,500 per year, to
qualifying 501(c)3 charitable organizations.
Our corporate giving further includes United Way, electric and heating bill assistance, safety, community support, and
diversity and inclusion programs. Employee donations support our company’s United Way campaign, and they also
donate their valuable time in our communities. In 2015, more than 92,000 volunteer hours were logged for various
initiatives including Days of Caring, Habitat for Humanity, food drives, tree planting and many other charity events.

Employee safety performance
Safety is a Core Value, and our first priority is that nobody gets hurt. Employee safety performance is tracked
according to the OSHA requirements. In addition, our company has a program to track and report near misses
and unsafe conditions. This prevents similar incidents from occurring elsewhere and helps to identify and correct
potential hazards to reduce risk to our employees.
