The Mojave Solar Project (MSP) is located on approximately 1,765 acres halfway between Barstow, CA and Kramer Junction, CA, and is nine miles northwest of Hinkley, CA.
The project is a nominal 250-megawatt (MW) solar electric generating facility, consisting of well-established parabolic trough technology to solar heat a heat transfer fluid (HTF). This hot HTF generates steam in solar steam generators, which expands through a steam turbine generator to produce electrical power from twin, independently operable solar fields (Alpha and Beta), each feeding a 125-MW power island. Each power island has a diesel engine-driven firewater pump for fire protection and a diesel engine-driven backup generator for power plant essentials. The sun provides 100 percent of the power supplied to the project through solar-thermal collectors; no supplementary fossil-based energy source (like natural gas) is used to produce electrical power.
On December 12, 2012, the California Energy Commission approved a Post-Certification Amendment (TN 68936) to eliminate the requirement for fire hydrant loops in the solar fields and revise Hazardous Materials Management Condition of Certification HAZ-7 regarding fire water loop infrastructure in the solar fields.

Power Plant Certification and Exemption Processes
The CEC has the exclusive authority to certify all thermal power plants 50 megawatts (MW) and larger and related facilities proposed for construction in California. The Application for Certification (AFC) process is a certified regulatory program under the California Environmental Quality Act (CEQA). As a certified regulatory program, the CEC does not prepare environmental impact reports (EIRs) in an AFC proceeding, but instead prepares environmental assessment documents that are functionally equivalent to EIRs. A certificate issued by the CEC is in lieu of any permit, certificate, or similar document otherwise required by any state, local or regional agency, or federal agency to the extent permitted by federal law, and supersedes any applicable statute, ordinance, or regulation of any state, local, or regional agency, or federal agency to the extent permitted by federal law.
