Other Combustion Turbine Projects Sited by the Energy Facility Site Evaluation Council
These projects were approved but never built. The Site Certification Agreements have expired and are no longer valid.
The Council completed its review of the Northwest Regional Power Facility (NRPF), Application No. 92-1 and the Governor approved the project and signed Site Certification Agreement on September 20, 1996. The proposed site iwas an approximate 1,200-acre parcel of land near the town of Creston in eastern Washington State. The power plants and their related facilities were to use approximately 75 acres.
Construction never began on this project and the Site Certification Agreement expired in September 2006.
Project Summary: The NRPF was composed of two combined-cycle units, each containing two combustion turbine generators, one steam turbine generator and two heat recovery steam generators. Exhaust gases from the combustion turbines would have been used to produce high energy steam in the four heat recovery steam generators (HRSGs). The steam from the HRSGs will then was to be piped to one of the two steam turbines in order to produce the remaining one-third of the plant's total output. If both dual units would have been built, the NRPF was expected to produce approximately 838 megawatts of electricity.
The facility proposed to use an air-cooled condenser cooling system rather than a circulating water evaporative cooling system. Other water used by the plants was to be purchased from the town of Creston. The water was tol be supplied to the plant via a pipeline to be constructed by the Applicant. The proposed pipeline would have left the town of Creston water system and cross approximately one quarter mile of agricultural land to the Lincoln Road right-of-way and then run along the road to the plant site.
Natural gas was to be delivered to the plants via a new pipeline proposed to be constructed between the Pacific Gas Transmission line near the eastern border of the state and the site. Siting and regulation of the proposed natural gas pipeline fell under the jurisdiction of the Federal Energy Regulatory Commission (FERC).
Electrical energy produced by the project was to be transmitted from the plants by Bonneville Power Administration (BPA) transmission lines. These off-site transmission facilities fell under the jurisdiction of BPA.
The Cowlitz Cogeneration Project was approved and a Site Certification Agreement was issued in February 1994. No construction or development of this project occurred and the Site Certification Agreement expired in February 2004. Council Resolution No. 308.
The project was proposed to be located on the Weyerhaeuser mill complex in Longview Washington. The proposed cogeneration project was to consist of two natural gas-fired combustion turbine generators with an expected capacity of about 155 megawatts each and a steam generator rated at 95 megawatts. Spent steam would have been used within Weyerhaeuser complex in production of paper products. Natural gas would have been provided by a new eight mile pipeline from the Northwest Pipeline and be licensed by the Federal Energy Regulatory Commission.
The Cowlitz Cogeneration Project was initially cosponsored and licensed to both Mission Energy and the Weyerhaeuser Corporation. In March 1996, at the request of Weyerhaeuser and Mission Energy, the SCA was amended and Mission Energy was removed as a cosponsor of the project. The amendment also changed the expiration date of the Site Certification Agreement to July 14, 1997.
In June 1997 Weyerhaeuser requested the Council extend the Site Certification Agreement. The Council held a public hearing on October 1, 1997 to receive comments regarding Weyerhaeuser's request. On October 13, 1997, the Council approved forwarding a recommendation to the Governor for approval. On December 1, 1997 Governor Locke approved Amendment No. 2 to the Site Certification Agreement which:
The Site Certification Agreement for this project expired in February 2004.
