A new day for solar power in Iowa

It’s no secret that we’re dedicated to our transition to cleaner, more renewable energy in every community we serve. As part of that dedication, we’re proud to announce our plans for adding the first portion of 400 megawatts (MW) of solar energy generation in Iowa.

In our filing with the Iowa Utilities Board (IUB), we detailed our intent to acquire 200 MW of solar energy and 75 MW of battery energy storage from Phase I and II of the Duane Arnold Solar Project that will be developed by wholly owned, indirect subsidiaries of NextEra Energy Resources, LLC in Linn County. Once operational, Alliant Energy will own and operate both projects.

Bringing our vision to life

This announcement is the first major milestone in executing our Clean Energy Blueprint in Iowa. Once operational, the project positions Alliant Energy as the largest combined solar and battery storage operator in the state.

Pairing battery storage with solar cost-effectively meets customer demand and ensures safe and reliable service for customers. The combination also contributes to a healthier environment and serves as a local economic catalyst as the company continues accelerating its transition to delivering cleaner, more renewable energy for customers and the communities Alliant Energy serves.

Strengthening the communities we serve

The development and construction of the 200 MW of solar energy and 75 MW of battery storage at the Duane Arnold Solar Project will create up to 200 new construction jobs. According to an economic impact study conducted by Strategic Economic Research, the two projects will have a projected combined positive economic output of up to $260 million on the state of Iowa (including up to $154 million in Linn County). That includes the cumulative ripple effects of new jobs, wages, tax revenue and other economic activity during construction and through the life of the projects.

“It’s part of our purpose-driven strategy of serving customers and building stronger communities,” said Terry Kouba, president of Alliant Energy’s Iowa energy company. “Our plan also keeps customer affordability at the forefront. We are excited to transition land from the decommissioned nuclear facility into the largest solar and battery storage facility in Iowa.”

Looking ahead

A decision on our filing from the IUB is anticipated in the second half of 2022. In the meantime, take a look at some of the other ways Alliant Energy is building a clean energy future.
