Minnesota officials approved expansion plans for the Xcel Energy Sherco Solar project that will become one of the largest in the nation. The expansion will add a 250-MW array to the 460-MW array, with all phases expected to be completed by 2025. The project, with a total capacity of 710 MW, will power more than 150,000 homes annually. Xcel plans to close its three coal-fired power plants in Becker in 2030.
