The Panoche Energy Center (PEC) is located within western Fresno County adjacent to the Panoche Hills approximately 2 miles east of Interstate 5 on West Panoche Road.
PEC is a 400-megawatt (MW) natural gas-fired, simple-cycle generating facility consisting of four General Electric LMS100 combustion turbine generators (CTGs) and associated equipment. Each CTG is equipped with water injection to the combustors for reducing production of oxides of nitrogen, a selective catalytic reduction system with 19 percent aqueous ammonia injection to further reduce NOx emissions, and an oxidation catalyst to reduce carbon monoxide.
Auxiliary equipment includes inlet air foggers with evaporative coolers, a step-up transformer, compressed air system, control enclosures, aqueous ammonia storage tank, natural gas fuel system, water treatment system, water storage tanks, wastewater system, and site stormwater drainage system. Process wastewater is disposed of using a deep well injection system.
Offsite improvements associated with PEC include a 400-foot paved access road south of West Panoche Road to the plant site, 2,400 linear feet of gas pipeline, a 300-foot transmission line to the Panoche Substation, and the Pacific Gas and Electric expansion of the Panoche Substation by approximately 1.1 acres south of the existing substation boundary.
