The Duane Arnold Solar Project is an estimated 200-megawatt (MW) solar array located in Lee County, Iowa. The Duane Arnold Solar Project will connect into the electrical transmission grid directly through the substation formerly used for the retired nuclear-powered Duane Arnold Energy Center. Once complete, the project will positively impact the environment and generate enough clean, low-cost energy to power at least 40,000 homes annually.
