FERC seeks comment on permit app for 34-MW hydro project

The Federal Energy Regulatory Commission on Dec. 10 issued a notice about an Aug. 3 application from Advanced Hydropower Inc. for a preliminary permit, under which it would study the feasibility of the McNary Dam Advanced Hydropower Project, to be located at U.S. Corps of Engineers’ McNary Dam near Plymouth in Benton County, Washington, and Umatilla in Umatilla County, Oregon.

The sole purpose of a three-year preliminary permit, if issued, is to grant the permit holder priority to file a license application during the permit term.

The proposed project would utilize flows at the existing McNary Dam, and would consist of these new features: a 52-foot-wide, 40-foot-high gated intake located on the upstream side of McNary Dam; a 32-foot-wide, 34-foot-high, 234-foot-long concrete penstock installed through McNary Dam; a 34-MW vertical shaft Alden turbine; a draft tube discharging flows to the existing McNary Dam tailrace; and a 1.24-mile-long, 13.8- or 23-kV transmission line interconnecting with the existing McNary Dam switchyard.

The estimated annual generation of the McNary Dam Project would be 148.92 gigawatt-hours.

The applicant contact is: Kurt Ross, Advanced Hydropower Inc., 925 Fairgrounds Road, Goldendale, Washington 98620, phone (509) 773-5650.

The deadline for filing comments, motions to intervene, competing applications (without notices of intent), or notices of intent to file competing applications is 60 days from the issuance of this Dec. 10 notice.
