GENERAL DESCRIPTION OF PROJECT

The Moss Landing Power Plant Project is a 1,060 megawatt (MW) natural gas-fired, combined cycle facility. The project site is located at the intersection of Highway 1 and Dolan Road, east of the community of Moss Landing near the Moss Landing Harbor, Monterey County, at the existing Moss Landing Power Plant site that was previously operated by PG&E for about 50 years.

The project replaced the existing electric power generation Units 1-5, (a total of 613 MW built in the 1950s and shut down in 1995), with two 510 MW, natural gas-fired, combined cycle, units (Unit1 and Unit 2). Units 1 and 2 each consists of two natural gas fired combustion turbine generators (CTGs), two unfired heat recovery steam generators (HRSGs) and a reheat, condensing steam turbine generator (STG). Units 1 and 2 both use seawater for once-through cooling. Units 1 and 2 have been in commercial operation since 2002, selling into the daily energy market and operating year around at various loads. There have been no significant equipment modifications or operational issues.

Retired Units 1-5 equipment (boilers, steam turbines, generators, condensers and stacks) were removed. Nineteen above ground Fuel Oil Tanks were also removed. PG&E took responsibility for past years of soil and groundwater contamination and has removed and remediated contaminated soil and groundwater through the guidance of the California Department of Toxic Substances Control.

In 2006, Duke Energy sold the plant to LS Power (LSP) Moss Landing LLC, a subsidiary of LSP General Finance Co. LLC. In April 2007, the power plant was purchased by Dynegy Moss Landing, LLC, a subsidiary of Dynegy of Houston, Texas.


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.
