Another solar plant project with battery energy storage systems to help power future data centers is in the works outside of Phoenix.
Salt Lake City, Utah-based Copia Power, which develops, builds, and operates grid-connected power and data center infrastructure, is working to rezone about 3,100 acres near Tonopah in the far West Valley for its latest project, the Belmont Energy Center, according to planning documents filed with Maricopa County.
Most of the project site – about 2,860 acres – would be for utility-scale solar energy generation, while about 320 acres would be used for a gas generation facility, BESS, and data centers, according to a project narrative.
It’s part of a planned 30,000-acre digital and power infrastructure campus in the Harquahala Valley, about an hour's drive west of Phoenix. Copia owns some of the project parcels, while others are owned by a group of investors.
