Gateway Generating Station (GGS), formerly Contra Costa Unit 8 Power Project, is a combined-cycle, natural-gas-fired power station in Contra Costa County, California, which provides power to half a million customers in northern and central California. Gateway Generating Station is on the southern shore of the San Joaquin River, in Antioch, and is one of more than ten fossil-fuel power plants in Contra Costa County.

Construction, which cost $386 million, began in 2001; the station began delivering power to customers in 2009. Its nominal capacity is 530 MW, with a peak capacity of 580 MW. It generates electricity using two combustion turbines, paired with heat recovery steam generators (HRSGs) that power one steam turbine. The facility is owned and operated by Pacific Gas and Electric Company (PG&E).

In June 2015, a lawsuit was filed against the Environmental Protection Agency to prevent the approval of the station's air-emissions permit; the suit was dismissed in October of that year. As of 2015, the only recorded injury that had ever occurred at the facility was in April 2009, when an employee tripped and chipped a tooth.
