The Rio Mesa Solar Electric Generating Facility was a proposed 500 megawatts (670,000 hp) solar thermal power project in Riverside County, California. The developers for the project were subsidiaries of BrightSource Energy, Inc.[1] The plant was expected to cost about $2 billion.[2]

The plant was to comprise two solar power towers, each with a generating capacity of 250 megawatts (340,000 hp). About 170,000 heliostats would have reflected sunlight to the receivers mounted on top of the 750-foot (230 m) towers.[2] The project was scaled down from 750 megawatts (1,010,000 hp) to 500 MW in May 2012, for which it has a power purchase agreement (PPA) with Southern California Edison (SCE).[3]

In December 2011, the California Energy Commission (CEC) accepted the application for certification for the Rio Mesa SEGF. In October 2012, Rio Mesa received preliminary approval from the CEC; final approval was needed by June 2013 to fulfill its PPA.[4] However, the discovery of a large deposit of Pleistocene fossils underlying part of the project's area delayed approval or construction.[5] In January 2013, BrightSource suspended the Rio Mesa project;[6] the project was formally cancelled in July 2013.[7]
