CPS Energy plans to shut down or convert its two remaining coal plants by 2028. The Board of Trustees of San Antonio's city-owned power utility voted 4-1 on Monday to pass a power generation planning portfolio. The plan includes a combination of gas, solar, wind, and energy storage, specifically excluding coal. CPS Energy will close the Spruce 1 coal plant and convert Spruce 2 to a natural gas facility. Climate activists are pleased with the plan to phase out coal, but they want natural gas to be eliminated as well.
