The Silver King Solar and Storage project, now called Silver King Energy Center, is back before Pinal County officials. The proposal includes up to 800 megawatts of solar photovoltaic generation, up to 800 megawatts of battery energy storage, and up to 400 megawatts of natural gas thermal generation. At full build-out, it could become the county’s largest energy development. The three applications will receive public hearings and votes at the January 15 Planning and Zoning Commission meeting.

The application covers 8,122 acres of Arizona State Trust Land northeast of Florence. Developers withdrew an earlier version of this project in October 2025. The Pinal Post previously reported on the initial application and the withdrawal.
