GENERAL DESCRIPTION OF PROJECT

Orange Grove Energy, L.P. (OGE) proposes to construct a simple-cycle power plant in northern San Diego County. The project would have a nominal electrical output of 96 megawatts (MW) with construction planned to start in winter 2008 with a six-month construction period. Operation is planned for June 2008. OGE has proposed the project in response to a San Diego Gas & Electric (SDG&E) Request For Offer for new peaking resources for supporting reliability of the local electricity system. This facility will likely be used during times of maximum demand for electricity such as hot summer intervals. Under an agreement with San Diego Gas & Electric (SDGE), OGE will be responsible for construction of the plant and an approximately 0.2-mile underground electric transmission line interconnection between the power plant and the existing SDG&E Pala substation boundary. OGE will operate the plant and under a land lease for a site on a larger parcel owned by SDG&E. It will have a tolling agreement for generating electrical power for SDGE.

The generating facility would include two 50 MW GE LM6000 PC SPRINT combustion turbine generators (CTG), a gas metering station, water and natural gas pipelines. Transmission interconnection to the Pala substation will occur within the limits of SDGE's contiguous parcel and would include an underground transmission line interconnection. The project would be fueled by natural gas delivered to the site via a 2-mile extension of an existing SDGE gas line.

The CTGs will be equipped with GE's SPRay-INTercooled (SPRINT) power boost technology to increase output from the plant, requiring water for power augmentation. OGE is proposing use of dry cooling technology for turbine cooling. A new 1.8-mile waterline will be constructed by Rainbow Municipal Water District between the existing water main and the site boundary to provide water for the project's process, domestic, and sanitary needs. The proposed water usage is estimated to be 117 acre/feet annually. Air emissions from the proposed facility would be controlled by using Best Available Control Technology including a water injection system, carbon monoxide catalyst as well as a selective catalytic reduction system that will further reduce emissions.

The proposed project site would occupy 8.5 acres within a 220-acre site which is located off Pala Del Norte Road, approximately 3.5 miles northeast of I-5 on SR-76, approximately two miles west of the community of Pala and16 miles west of Fallbrook. The property is currently zoned General Agricultural (A72) in the San Diego County general plan which would accommodate the construction of a power plant. An existing SDGE Pala Substation is located on a contiguous SDPE parcel south of the project site. The site is currently occupied by a former citrus grove.


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.
