The proposed San Gabriel Generating Station (SGGS) will consist of a natural gas-fired combined cycle power plant and associated linear facilities. It is proposed by San Garbriel Generation, LLC, a subsidiary of NRG.

The SGGS will be a (2x1) configuration which will consist of two combustion turbine generators (CTG), two supplementally fired heat recovery steam generators (HRSG), one steam turbine generator (STG), and ancillary equipment.

The linear facilities will consist of the natural gas line, makeup water supply line, fire protection water line, potable water line, process wastewater line, and the transmission line that connects to the Southern California Edison Company's (SCE) future Rancho Vista substation.

The project, if constructed, would generate 696 megawatts (MW) average new output of electricity. Per Committee Order dated June 2, 2009, the project has been suspended through December 31, 2009 due to the uncertainty of the project being able to secure emission reduction credits within the South Coast Air Quality Management District's Priority Reserve Credit program.

The proposed project will be fueled with pipeline-quality natural gas that will be delivered to the power plant site.

Except for approximately 200 feet of gas line and 400 feet of transmission line, the SGGS will be primarily sited within the existing 60-acre Etiwanda Generating Station (EGS) property located on Etiwanda Avenue in Rancho Cucamonga, San Bernardino County, California.

Energy Commission Facility Certification Process

The California Energy Commission is the lead agency (for licensing thermal power plants 50 megawatts and larger) under the California Environmental Quality Act (CEQA) and has a certified regulatory program under CEQA. Under its certified program, the Energy Commission is exempt from having to prepare an environmental impact report. Its certified program, however, does require environmental analysis of the project, including an analysis of alternatives and mitigation measures to minimize any significant adverse effect the project may have on the environment.
