GENERAL DESCRIPTION OF PROJECT

In August 1999, the California Energy Commission (Energy Commission) approved the nominal 500 megawatt (MW) combined cycle Pittsburg District Energy Facility. The project is located on a 12-acre site on East 3rd Street, west of the intersection of East 3rd and Columbia in the City of Pittsburg, in eastern Contra Costa County. The site is on the northwest corner of property owned by USS-POSCO Industries.

In March 2000, a petition to amend was approved by the Energy Commission to change the name of the project From Pittsburg District Energy Facility to the Los Medanos Energy Center, to add a second circuit to the 115 kilovolt (kV) transmission line to increase the reliability of electricity to USS-POSCO, and to modify the fuel gas pipeline to connect with the gas line at the Delta Energy Center project and tie in with the Pacific Gas & Electric (PG&E) Line 400, and modify the steam line to allow the project to serve as back up steam supplier for Dow Chemical.

The project consists of two trains of combustion turbine generators with a steam turbine generator. Natural gas is burned in the combustion turbine generators, which converts the thermal energy into mechanical energy required to drive the compressor and electric generator. The combustion turbine trains include exhaust stacks and step-up transformers, heat recovery steam generator (HRSG) units, steam turbine generator units and their transformers, and water treatment and cooling towers. A 115 kilovolt (kV) high voltage switchyard is on the west side of the project site. Reclaimed water for turbine cooling is supplied from the Delta Diablo Wastewater Treatment Facility located in the City of Antioch.


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.
