The Crockett Cogeneration Project (CCP) is located in the unincorporated area of Crockett, Contra Costa County, within the C&H Sugar Refinery (C&H) compound, which consists of an extensive industrial complex containing large brick, steel, and concrete buildings, a steel conveyor system, wooden wharf, large bulk sugar storage bins, and a flue gas stack for the existing C&H boilers.
CCP is a 240-megawatt (MW) an existing, natural gas-fired cogeneration facility provides the steam required to operate the adjacent C&H. CCP consists of a General Electric (GE) 7FA gas turbine generator, heat recovery steam generator, steam turbine, single-shaft electric generator, air cooled steam condenser to condense steam into water for recirculation, three back up auxiliary boilers, supplemental duct firing, selective catalytic reduction equipment for control of nitrogen dioxide (NOx) emissions, water treatment area, switchyard and substation.
On March 14, 2012, the California Energy Commission approved a Post-Certification Amendment (TN 64473) to amend the project by installing electric motor driven natural gas compression equipment at the facility to ensure that the facility could be fully responsive to demand and need regardless of the delivery pressure of natural gas by PG&E. The need to install the equipment arose in the wake of PG&E’s de-rating of its natural gas supply and delivery pipeline system which resulted in pressure reductions that were preventing the Crockett Cogeneration Project from meeting its power delivery obligations under its power purchase agreement with PG&E.
Power Plant Certification and Exemption Processes
As required by the Warren-Alquist Act, the Energy Commission monitors Commission-certified energy projects throughout construction, operation, and closure to ensure compliance with the conditions of certification imposed by the Commission’s Final Decision for approving the projects.
