Large Solar Energy Projects

The table below provides information about projects that have filed applications under the Energy Commission's jurisdiction (thermal power plant projects 50 MW or larger).

California's electric utility companies are required to use renewable energy to produce 33 percent of their power by 2020. A main source of renewable power will be solar energy.

Solar thermal projects (above 50 MW) require approvals from both the BLM and the Energy Commission prior to construction. Therefore, to provide joint National Environmental Protection Act (NEPA) and California Environmental Quality Act (CEQA) review and a more efficient process, the BLM and Energy Commission have entered into a Memorandum of Understanding (MOU) (PDF file, 14 pages, 140 kb). This MOU also has attachments listing the solar projects the BLM is aware of (as of July 2007) and the time line for the joint review process.

Earlier Large, Solar Projects Producing Power

Prior to the Renewable Portfolio Standards in 2002, 13 solar thermal power projects were planned in California, with 11 of those filing applications with the Energy Commission. Nine projects (Solar Energy Generating Station - SEGS I to IX), totaling 354 MW, were built. SEGS III to IX are owned by NextEra™ Energy Resources (formerly FPL Energy), and SEGS I and II are owned by Cogentrix Solar Services - a wholly owned subsidiary of Cogentrix Energy LLC (Charlotte, NC), which purchased former owner Sunray Energy Inc. in early 2009.

One large photovoltaic (PV) array was built by the Sacramento Municipal Utility District near its Rancho Seco Nuclear Plant. It went on line in August 1984 and has an installed capacity of 3.19 MW.
