EFSEC: Chehalis Generation Facility

Chehalis Generation Facility

The Chehalis Generation Facility is a natural gas-fired combined-cycle facility. The 30 acre project site is located south of Chehalis, Washington, east of Interstate 5 in the Chehalis Industrial Park in Lewis County (location map).

In March 1997, Governor Locke approved the original Site Certification agreement (license to construct and operate) of the Chehalis Generation Facility. The facility licensed at that time proposed a total generating capacity of 460 MW, with the capability to provide approximately 100,000 lb/hr of steam to a process host. In March 2001, Governor Locke approved the first amendment to the Site Certification Agreement, allowing an increase in generating capacity from 460 MW to 520 MW, a change to a dry cooling system and associated water supply and discharge modifications, and allowing the facility to operate as a "merchant plant".

Construction began in May 2001 with commercial operations starting in October 2003.

In September 2008 EFSEC (through Order No. 836 and Resolution No. 325) transferred the Site Certification Agreement (Amendment No. 2) to PacifiCorp upon completion of the sale of the project to PacifiCorp.
