NextEra Energy Resources of Florida plans to convert the idle Duane Arnold Energy Center in Palo, Linn County into a new solar farm. Previously, the 615-MW nuclear power plant powered 600,000 homes and the new solar farm is expected to surpass that with a capacity of 690-MW.

The solar farm will span 3,500 acres around the energy center and will include 60-megawatts (MW) of AC-coupled batteries for power storage. NextEra plans to invest $700 million over 30 years into the project resulting in $41.6 million in tax revenue and 300 construction jobs. The company hires as many workers from the local area as possible for these projects. 

The Duane Arnold nuclear power plant began operating 45 years ago and was expected to be decommissioned at the end of October 2020, however, by 2019 it was clear the plant no longer fit Iowa’s energy needs. 

NextEra has the largest renewable energy production portfolio in the United States. The company operates solar projects in 27 states and Canada with around 2,600 MW of universal and small-scale solar operating assets. This will be NextEra’s first solar project in Iowa. 

The project is expected to begin construction in winter 2022 and be operational by the end of 2023.
