Cedar Rapids Gazette: Alliant Energy plans to file a proposal today with the Iowa Utilities Board to buy a large-scale solar project near Palo from NextEra Energy and further develop that project into the state’s largest solar and battery storage facility. The plan calls for NextEra to continue developing 200 megawatts of solar energy and 75 megawatts of energy storage as the first two phases of a planned solar project near the site of the decommissioning Duane Arnold Energy Center. Alliant would buy the completed project from NextEra, adding another 200 megawatts of solar at a later date, Alliant announced Tuesday morning.
