On May 4, 2001 the Modesto Irrigation District (MID) filed a Small Power Plant Exemption (SPPE) to request approval from the California Energy Commission to construct an 80-megawatt (MW) nominal natural gas-fired combined cycle generating facility. The project would be located on a 2.5 acre portion of an overall 7 acre site with an existing 49.4 MW generating facility on Woodland Avenue, in Modesto, California, County of Stanislaus.

The 80-megawatt natural gas-fired combined cycle will consist of one modern combustion turbine and a condensing steam turbine. The project will use a convention drum-type heat recovery steam generator (HRSG), or a once through steam generator (OTSG) HRSG. Expansion of the existing switchyard will also include two new bays. Approximately 1.2 miles of new 69kV subtransmission line, approximately 6 miles of system reinforcements to an existing Pacific Gas & Electric natural gas supply line, and approximately 1 mile of new water line would be constructed as part of the proposed project.

Project Description

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.
