Gateway Generating Station (GGS), formerly Contra Costa Unit 8 Power Project, is a
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

Construction
A proposal to construct the facility, originally called "Contra Costa Unit 8 Power Project", was filed with the
In July 2005,
PG&E wanted to change the name of the project from "Contra Costa Unit 8 Power Project" to "Gateway Generating Station"; this name was chosen to show that the "plant represents the 'Gateway' to the future of electric power generation"[3] and was required to file a request for this. The Energy Commission approved this request five months later. During that time, in December 2006, PG&E became the sole owner of the project.[7]
Construction finally resumed in February 2007, making Gateway the first new plant built by PG&E in nearly twenty years.[3] The project was expected to cost about $370 million (equivalent to $544 million in 2023), employ as many as 400 workers at its peak, involve approximately one million worker-hours, and to provide electricity to customers by 2009.[3] The engineering, procurement, and construction of the plant were managed by Black & Veatch.[8] It was expected that PG&E would pay approximately $1.5 million to Contra Costa County annually in property tax.[3]
The work for underground piping and powertrain equipment included loading, setting and alignment of heavy haul items, in addition to installation of pipe supports, piping, in-line instrumentation, platforms and enclosures. This portion of the work, along with associated management cost, encompassed 152,000 direct man-hours of labor over 21 months.[9] By July 2008, construction was "two-thirds" finished.[10] The gas turbines were first fired in November 2008;[7] commercial operation, supplying power to nearly 400,000 customers, began on January 4, 2009.[7][11] Randy Livingston, PG&E's vice president of power generation, said to the Brentwood Press that the project came "ahead of schedule, on budget, and we had no lost-time injuries during the entire construction of the plant".[11] The overall cost of the plant was $386 million.[11]

The air-cooled condenser system, made by SPX Dry Cooling (now SPG Dry Cooling), is designed for a maximum ambient temperature of 104 °F (40 °C) and back pressure of 5 inches of mercury (0.017 MPa). It consists of six "streets" of six fans each, for a total of 36 fans; each fan is operated at 4160 volts by a 250-horsepower motor.[13] A grid of 24 vertical screens installed beneath the fans shields them from wind.[20]

Safety
In April 2009, an employee tripped and hit their face on a pump, chipping a tooth; as of 2015, this was the only recorded injury that had ever occurred at the station.[27] In 2012, to avoid arc flash hazards to employees when racking in breakers, contactors, and grounding buggies, a racking system was installed which uses cameras and actuators to allow these tasks to be performed remotely.[28] In 2014, a steam-cycle performance assessment resulted in an update of the cycle-chemistry manual, upgrade of the chemistry logging systems, and purchase of new analytical equipment.[29][30]
A fall 2017 audit/inspection by Contra Costa Health Services Hazardous Materials Programs (CCHSHMP), to ensure compliance with California Accidental Release Prevention (CalARP) program requirements, found 12 corrective actions for PG&E to implement, and made 18 further recommendations. There had not been any incidents related to regulated CalARP materials in the five years prior to the audit.

Compared to older fossil-fueled plants, this 580 MW station produces dramatically less carbon dioxide for every megawatt-hour produced. "Dry" cooling technology means the plant uses 97 percent less water.
