GENERAL DESCRIPTION OF PROJECT
On May 7, 1999, Duke Energy Moss Landing LLC filed an Application for Certification (AFC) seeking approval from the California Energy Commission (Energy Commission) to construct and operate the proposed 1,060-megawatt (MW) Moss Landing Power Plant Project. The project is proposed to be located at the existing Moss Landing Power Plant site that was previously operated by PG&E for about 50 years. This site is located at the intersection of Highway 1 and Dolan Road, east of the community of Moss Landing near the Moss Landing Harbor.
The project, as proposed by Duke Energy, consists of replacing the existing electric power generation Units 1-5, (a total of 613 MW built in the 1950s and shut down in 1995), with two 530 MW, natural gas-fired, combined cycle, units. Each combined cycle unit 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). Each combined cycle unit will use seawater for once-through cooling. Duke Energy also proposes to upgrade each of the existing Units 6 and 7 by 73 MW.
Duke also planned to remove eight 225-foot stacks and ten large oil tanks.
In 2006, Duke Energy sold the plant to LS Power (LSP) Moss Landing LLC, a subsidiary of LSP General Finance Co. LLC. The 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.
