The future of solar energy is bright
We believe better is always possible. A sensible, planned move to clean energy sources is the way to solve many of our energy challenges. Our energy mix combines clean and renewable sources with traditional ones. We have been transitioning our system to a more balanced and diverse energy mix. We are also reducing emissions by adding solar and wind energy, and natural gas generation.
How we use solar energy
Madison energy learning lab
We’ve built an energy learning lab at our Madison, Wis. general office with several types of solar structures, multiple electric vehicle charging stations and an energy battery storage system.
Dubuque Solar Project
The Dubuque Solar project is a combination of two sites, the West Dubuque Solar Garden and the Port of Dubuque Solar Garden. This project earned the Envision Platinum rating for sustainable infrastructure – the highest Envision award level. This is the first solar project to receive Envision recognition, and second project in Iowa to receive an Envision Platinum rating. The first was our Marshalltown Generating Station.
West Dubuque Solar Garden
The West Dubuque Solar Garden is the largest single solar project in Iowa. In September 2017, the West Dubuque Solar Garden came online to bring clean energy to customers. This five-megawatt site uses more than 15,000 panels.
The annual output of this solar garden is equal to the annual usage of about 727 average Iowa homes. The site covers 21.1 acres of land in a new industrial park in Dubuque, Iowa. This land was sloped and not ideal to build a large manufacturing facility. However, this slope is ideal for a solar garden. Because of the slope, we are able to place the panels closer together without casting shade on the back rows – just like stadium seating.
The West Dubuque Solar Garden and the Port of Dubuque Solar Garden are the result of innovative partnership with the city of Dubuque and the Greater Dubuque Development Corporation.
Port of Dubuque Solar Garden
The Port of Dubuque Solar Garden welcomes travelers from the tri-states (Iowa, Wisconsin and Illinois). This project is located between downtown Dubuque and the Mississippi River. The Port of Dubuque Solar Garden features an educational display and information to teach visitors about advancements in clean energy technology.
This is a 1.2-megawatt solar garden, and its annual output is equal to the annual usage of about 126 average Iowa homes. It started generating clean energy in September 2017.
The Port of Dubuque Solar Garden is located on a former industrial site, currently owned by A.Y. McDonald Co.
Indian Creek Nature Center (Cedar Rapids, Iowa)
The Amazing Space facility at the Indian Creek Nature Center in Cedar Rapids reached Net Zero status in 2018. An Alliant Energy owned solar array, built on site, delivers enough energy to account for the buildings annual usage. This achievement puts the building in a class of its own as Indian Creek Nature Center is the first commercial building in Iowa to pursue Net Zero Energy certification.
There are 420 solar panels on site, some on the roof and some on the ground. You can see real-time information on how much energy the panels are producing today, this month and even this year. This data helps us identify what works best in our climate. This helps us plan to meet the energy needs of our customers as efficiently and cleanly as possible.

Rock River (Beloit, Wisconsin)
In winter 2016, we began providing our customers with energy from the 2.3-megawatt Rock River solar project through a 10-year power purchase agreement (PPA) with Hanwha Q Cells USA. The solar field is located on our closed Rock River Generating Station landfill site in the Town of Beloit.
The installation is the first Wisconsin utility-scale solar installation located on a closed landfill site and represents another step in modernizing our Town of Beloit energy campus. When the facility went into service, it was the largest solar generating station in Wisconsin.
Riverside Energy Center (Beloit, Wisconsin)
Our proposed 700-megawatt natural gas-fired generating station will include a two-megawatt solar installation to offset the facilities’ power needs and improve the project’s environmental profile.
