The Palomar Energy Center (PEC) is situated within the Escondido Research and Technology Center industrial park, southwest of the intersection of Vineyard Avenue and Enterprise Street in the city of Escondido, San Diego County. The project site is about 600 feet, west of Interstate 15 and south of State Highway 78.
The 500-megawatt facility consisting of two combustion turbine-generators equipped with dry low combustors and evaporative inlet air coolers, two heat recovery steam generators equipped with duct burners, selective catalyst reduction and oxidation catalyst emission control systems, a steam turbine-generator, and associated auxiliary systems and equipment. The project also includes a 230-kilovolt switchyard that interconnects with a San Diego Gas and Electric (SDG&E) Company electric transmission line located immediately adjacent to the project site. The power plant is fueled by natural gas delivered via the SDG&E gas system. An existing SDG&E natural gas pipeline with sufficient capacity to serve the project is located immediately adjacent to the project site.
