584 -megawatt, gas-fired, combined-cycle power plant entered operations in 2002
and generates electricity for the PJM power market.
-- Morris Power Plant -- Calpine has a 100% interest in this 156-megawatt ,
gas-fired, cogeneration plant. It would consist of five 100 MW
combustion turbine generators and would connect to the electricity grid
through a 230 kilovolt (kV) line to the SCE Walnut Substation .
