Project Description

On September 8, 2021, the California Energy Commission Executive Director granted a license for two temporary power generators at the site of the decommissioned Greenleaf 1 Cogeneration facility in accordance with Governor Newsom’s Proclamation of State of Emergency issued on July 30, 2021, and the CEC’s August 17, 2021, Order number 21-0817-2 regarding the process for licensing new emergency and temporary power generators. Calpine Greenleaf Holdings, Inc. is licensed to temporarily host and operate two 30 megawatt (MW) General Electric Company (GE) TM2500-G4 gas turbine package units at the site of the decommissioned 49.5 MW Greenleaf 1 Cogeneration facility in Sutter County. The approximately 60 MW natural gas-fired simple cycle electric generating facility, named Greenleaf 1, is sited adjacent to and east of the Sutter Energy Center (SEC). The SEC is a 578 MW natural gas-fired, combined-cycle electrical generating facility that was certified by the CEC (97-AFC-02) on April 4, 1999 and began commercial operation on July 2, 2001. The temporary power generators are available to be deployed during a grid emergency due to a sudden energy supply shortage in California resulting from an extreme heat wave or wildfire event, as designated and directed by the California Independent System Operator.
