RMP - Pacific Gas & Electric (PG&E) Gateway Station

3225 Wilbur Avenue, Antioch, California

Pacific Gas and Electric (PG&E) operates the Gateway Generating Station, a nominal 530-megawat (MW) natural gas-fired combined cycle electric power generating facility. The Gateway Generating Station is located on Wilbur Avenue, one mile northeast of the City of Antioch, in Contra Costa County, California, on the southern shore of the San Joaquin River. Highway 4 and the Antioch Bridge are just east of the site. The river borders the north side, while a recreational marina, open space and additional industrial land uses occur east of the site. The Gateway Generating Station uses aqueous ammonia in its selective catalytic reduction (SCR) system to reduce the emissions of nitrogen oxides (NOx) to the atmosphere.
