Project Description

The Gateway Generating Station (GGS), licensed as the Contra Costa Unit 8 Power Project, is located within the site complex of the existing Contra Costa Power Plant (CCPP) in Contra Costa County, just north of the City of Antioch, Contra Costa County.

GGS is a nominal 530-megawatt natural gas-fired, combined-cycle facility consisting of two natural gas-fired combustion turbine generators, two heat recovery steam generators (HRSGs), and a steam turbine generator. Additional project facilities include two 195-foot tall exhaust stacks on the heat recovery generators, a 10-cell water cooling tower, storage tanks, a control building, and electrical power transformers and transmission facilities to interconnect with the existing Pacific Gas and Electric switchyard on the CCPP site complex, back up diesel generators for either fire pumps or for a spare generator step up transformer, additional 40,000 gallon storage tank, and operational related utility upgrades and additional safety improvements.

On January 3, 2007 the California Energy Commission (CEC) approved a Post-Certification Amendment (PCA) (TN 39055) to change the project name from Contra Costa Power Plant Unit 8 to Gateway Generating Station (GGS).

On August 1, 2007, the CEC approved a PCA (TN 41809) to amend the proposed GGS to eliminate use of San Joaquin River water for cooling and replace the wet cooling tower with an air cooled condenser and a wet surface air cooler, and the elimination of the use of steam power augmentation and the addition of an oil/water separator several other design modifications.
