The Lake View Geothermal Project (Unit 17) is in Sonoma County near the Sonoma County line, in the Geysers Known Geothermal Resource Area along the ridgeline of the Mayacamas Mountains with moderately steep terrain, approximately 15 miles west of the town of Cobb. Unit 17, originally known as Pacific Gas & Electric Company’s (PG&E) Geysers Unit 17 Geothermal Project was certified by the Energy Commission (CEC) in September 1979 and began commercial operation in March 1982.
Unit 17 is a dry-steam geothermal plant that was designed to provide up to 110 MW; however, due to reduced steam pressures, the plant currently supplies about 52 megawatts of base-load electricity to northern California's power grid. Major structures include the turbine building, cooling towers, hydrogen sulfide abatement, and the service building.
In April 1999, the CEC granted a transfer of ownership of Lake View Geothermal (Unit 17), the former PG&E Geysers Unit 17 Geothermal Project to Geysers Power Company, LLC, a wholly owned subsidiary of the Calpine Corporation.

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.
