The river borders the north side, while a recreational marina, open space and additional industrial land uses occur east of the proposed project. The CCPP site complex measures about 200 acres. The proposed Unit 8 would occupy 20 acres of the northeast corner of the complex. Units 4 and 5 were added in 1953, while Units 6 and 7 were placed in operation in 1964. In the combined cycle process, electricity is created from the combustion turbines and the steam turbine.
Natural gas is burned to fire the combustion turbines.
Exhaust heat from the two combustion turbines is then used to generate steam in the HRSGs, which in turn drives the steam turbine electricity generator. The natural gas fuel for Unit 8 would be supplied by the existing gas pipeline. Cooling water for Unit 8 would be supplied by re-use of the cooling water from the existing Units 6 and 7. According to the applicant's project description, no net increase in water withdrawal from the San Joaquin River is anticipated. As described by the applicant, no additional electric transmission lines outside of the CCPP complex are needed to transmit Unit 8's electricity to the regional transmission grid.
