The CPV Sentinel Energy Project (CPVS) is being permitted as a nominally rated 850 megawatt (MW) electrical generating facility based on eight natural gas-fired General Electric (GE) LMS100 combustion turbine generators (CTGs) operating in simple cycle mode. The project will supply quick-start peaking capacity, energy, and ancillary services into the California Independent System Operator’s (CAISO) Los Angeles Basin Local Capacity Requirement (LCR) Area. The plant will be equipped with Selective Catalytic Reduction (SCR) and Carbon Monoxide (CO) equipment to reduce plant emissions of NOx and CO. In addition plant will utilize a Zero Liquid Discharge System to eliminate all liquid waste water discharge from the site.

The Project will be built by in a continuous fashion with Phase 1 consisting of the first five units and Phase 2 consisting of three additional units. Construction of the Project is expected to occur during a 26 month period (from February 2009 to April 2011). Operation of the first five turbine units is planned to begin by July 31, 2010 and Phase 2 by April 10, 2011.

The CMEEC A.L. Pierce Re-powering Project consists of one simple cycle General Electric 7EA combustion turbine relocated to an existing building after four years of storage. Due to the plant’s location in a residential neighborhood, the design incorporated sound walls, acoustically treated equipment and building modifications to meet State mandated noise levels. In addition minimum impact was imposed upon the building while maintaining its original façade concept while the combustion turbine was installed inside the building. These steps have permitted the operation of a power plant in close proximity to residents without visual and environmental impacts.
