The future of solar energy is bright
Iowa solar projects
Dubuque Solar project
The Dubuque Solar project is a combination of two sites, the West Dubuque Solar Garden and the?Downtown 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.
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 Downtown Dubuque Solar Garden are the result of innovative partnership with the city of Dubuque and the Greater Dubuque Development Corporation.
Downtown?Dubuque Solar Garden
The?Downtown 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 Downtown 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?Downtown Dubuque Solar Garden is located on a former industrial site, currently owned by A.Y. McDonald Co.
Indian Creek Nature Center solar project
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.

Marshalltown Generating Station solar project
In spring 2017, our 706-megawatt, highly efficient natural gas generating station went into operation in Marshalltown, Iowa.? In early 2019, we will begin construction of a 2.5-megawatt solar installation that will provide clean energy to our customers. When completed in late 2019, the solar garden’s power will offset local electric demand and improve our sustainability footprint in Marshalltown.
Wisconsin solar projects
Madison solar demonstration project
We’ve created an energy learning lab at our Madison, Wis. campus with several types of solar structures, multiple electric vehicle charging stations and a battery energy battery storage system.
You’ll find 1,325 solar panels, 30 ground-mounted solar features, nine roof-mounted solar arrays, five solar parking canopies, 18 electric vehicle chargers, plus more, on our office property.
The unique demonstration project went into service in early 2016. It continues to grow through added educational outreach resources and more structures. For example, there is now real-time performance data available through a web-based dashboard.
Rock River solar project
?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, just to the north of the city 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.
West Riverside Energy Center integrated solar project
Our 730-megawatt natural gas-fired generating station under construction?on our Town of Beloit energy campus will include a 4-5-megawatt solar installation integrated into the generating station. The solar power will be used to offset the facilities’ auxiliary power needs and improve the project’s sustainability.
The West Riverside Energy Center natural gas and solar facilities are expected to be completed and in service by early 2020.
