Kittitas Valley Wind Power Project
The Kittitas Valley Wind Power Project is located in unincorporated Kittitas County, Washington, approximately 12 miles west of Ellensburg (location map)The project is located on approximately 5,400 acres of privately and publicly owned forest and rangeland.
The current project consists of 48 wind turbines, a Sagebrush-owned electrical substation, a BPA-owed substation, an operations and maintenance building, and associated supporting infrastructure. EFSEC permitted the project for up to 52 turbines and Sagebrush retains the option to construct four more turbines. The project dispatches electricity through the Bonneville Power Administration transmission system.
Background: In January 2003, Sagebrush Power Partners, LLC, submitted an application for site certification to EFSEC for its Kittitas Valley Wind Power Project. This Project is an alternative energy facility as defined in RCW 80.50.020(17). Sagebrush chose to receive site certification from EFSEC for the Kittitas Valley Wind Power Project pursuant to RCW 80.50.060(2). Application cover letter (1 page - PDF)
On March 27, 2007, EFSEC issued Order No. 826 Findings of Fact, Conclusions of Law, and Order Recommending Approval of Site Certification Agreement. Executive Summary (19kb) Order No. 826 By letter dated June 22, 2007, Governor Gregoire requested EFSEC reconsider the recommended setback for some of the turbines from non-participating landowners' residences.
On August 8, 2007, EFSEC approved Order No. 831 which recommended the Governor approve the Kittitas Valley Wind Power Project with changes to the proposed Site Certification Agreement. These changes would require consideration of visual impacts as the highest priority during the final siting (micro-siting) of the turbines located within 2,500 feet of non-participating residences. Order No. 831, with a revised proposed Site Certification Agreement was delivered to the Governor on August 15, 2007.
On September 18, 2007, Governor Gregoire approved the Kittitas Valley Wind Power Project, and construction began in mid-March 2010. The project became operational in late-autumn 2010. Governor Gregoire's approval letter to the EFSEC Chair.
In November 2008, the Washington Supreme Court upheld the Governor's approval.
General Description of the Project:
The Project will consist of a maximum of sixty-five (65), 3-bladed wind turbines on tubular steel towers, not exceeding a maximum height (hub height plus blade tip height) of 410 feet. The nameplate capacity will be between 98 and 195 megawatts depending on the size of turbine used (1.5 or 3.0 megawatt). The Project would interconnect directly with either Puget Sound Energy's 230kV Rocky Reach-White River transmission line or Bonneville Power Administration's (BPA) Grand Coulee-Olympia or Columbia-Covington 287 kV lines, all of which pass directly over the Project site.
The Kittitas Valley Wind Power Project turbines are proposed to be located on the ridges located on either side of Highway 97, roughly halfway between Ellensburg and Cle Elum.
