The Federal Energy Regulatory Commission on July 30 issued a three-year preliminary permit to Howard A. Hanson Power LLC so it can study the feasibility of the 5-MW Howard A. Hanson Hydroelectric Project.
This project is to be located on Howard A. Hanson reservoir near Enumclaw in King County, Wash. The project would be located on lands managed by the U.S. Army Corps of Engineers.
The proposed project would use the existing earth and rockfill Howard Hanson Dam owned and operated by the Corps with a total storage capacity of 136,700 acre-feet at a normal maximum operating elevation of 1,141 feet mean sea level and would consist of: modifications to the existing outlet works to create four 150 to 300-foot-long, 48-inch-diameter steel penstocks each housing an inline turbine/generation unit for a total capacity of 5 NW; and an overhead or buried 1-mile-long, 15-kV transmission line extending from the project to an existing local utility’s line. The estimated annual generation of the Hanson Project would be 26 gigawatt-hours.
During the course of the permit, the commission expects that the permittee will carry out prefiling consultation and study development leading to the possible development of a license application.
