Project Description

The Gilroy Cogeneration Project (GCP) located at 1400 Pacheco Pass Highway, Gilroy, Santa Clara County.

GCP is a 115-megawatt is a natural gas-fired, combined-cycle cogeneration facility consisting of one combustion turbine, one heat recovery steam generator, one steam turbine and two auxiliary boilers. GCP produces and sells thermal energy to a thermal host, Olam West Coast, under a long-term contract.

On August 7, 1996, the California Energy Commission (CEC) approved an ownership change (TN 3114) from Gilroy Energy Company to Calpine Gilroy Cogen, LP.

On July 13, 2005, the CEC approved a Post-Certification Amendment (PCA) (TN 36080) to change the source of cooling water supply from wells to Title 22 quality recycled wastewater from the South County Regional Wastewater Authority facility located adjacent to the GCP site.

On April 10, 2013, the CEC approved a PCA (TN 70281) the installation of new Selective Catalytic Reduction units on GCP’s two auxiliary boilers allowing the project to comply with changes to the Bay Area Air Quality Management District regulations for emissions of NOx for auxiliary boilers.

Calpine Corporation, the project owner, entered into a Resource Adequacy contract for the plant with Southern California Edison beginning in January 2014.
