The California Energy Commission is responsible for the certification and compliance of thermal power plants 50 megawatts (MW) and larger, including all project-related facilities in California. The agency's jurisdiction covers publicly and privately-owned lands. Through its certification process, the Energy Commission ensures that power plants and related facilities are reviewed expeditiously and authorized if they are safe and environmentally acceptable. Current and historical data is provided in the links below. The Energy Commission's Siting, Transmission, and Environmental Protection main page provides additional program and policy information.
