The company acquired Gateway from Mirant Corp through the settlement of overcharges for power that was sold during the Western power crisis in 2000-01. That was to be Unit 8 at Mirant’s Contra Costa plant.

The Gateway plant comprises two 180 MW gas turbines and one 250 MW heat recovery steam turbine. The Gateway plant has a baseline capacity of around 530 MW but can reach approximately 610 MW of peaking power.

PG&E, which is based in San Francisco, owns and operates approximately 6,200 MW of generating capacity, transmits and distributes electricity to around 5.3 million customers and natural gas to 4.2 million customers, and markets energy commodities in northern California.
