The Satsop Combustion Turbine Project consists of two combustion turbine generators on a "two on one" configuration with a  single steam turbine generator.  The Project will produce a nominal output of approximately 530 megawatts per year, with a maximum annual output of approximately 650 megawatts.  The Project is a 20-acre site within the Satsop Redevelopment Park in Grays Harbor County (location map).  The entire 20-acre site was previously developed, including grading and surfacing with gravel and asphalt, and used as an equipment and material laydown area during construction of WNP-3 and WNP-5. 

The Site Certification Agreement for the Satsop Nuclear Project (WNP 3/5) site was amended in 1996 to allow for construction of a 450 MW gas turbine. The nuclear power projects were removed from the Site Certificate in 1999.  In April, 2001 the Site Certificate was amended again to allow the current 650 MW gas turbine project.  Construction started on the combustion turbine project in September 2001 but was suspended in September 2002 at approximately 56% complete.

In April 2005 the Site Certification Agreement was amended to reflect the sale of the project to Grays Harbor Energy LLC (a subsidiary of Invenergy Inc.) from Duke Energy.   Construction was restarted in February 2007 with commercial operation starting in April 2008.

In April 2001, the Council authorized a technical amendment to the Site Certification, allowing: the replacement of the originally permitted Westinghouse turbines with General Electric turbines; a modification of  the facility configuration  from a dual "one-on-one" configuration (two separate but identical combustion turbine generator - steam turbine generator trains), to a single "two on one" configuration (two combustion turbine generators - one steam turbine generator facility); an increase of  the nominal output of the facility from 490 MW to 530 MW; an increase of the a maximum output of approximately 650 MW by utilizing duct firing; and removal of the capability to use diesel oil as a backup fuel. Construction started on the combustion turbine project in September 2001 but was suspended in September of 2002 at approximately 56% completion. In April 2005 the Site Certificate was amended to reflect the transfer of ownership from Duke Energy to Grays Harbor Energy LLC (a subsidiary of Invenergy Inc.). Invenergy restarted construction in February 2007.
