FERC seeks input on permit app for small hydro project in California

The Federal Energy Regulatory Commission on Jan. 5 issued a notice about a December 2014 application from Twain Resources LLC for a preliminary permit under which the company would study the feasibility of the Easygo Hydroelectric Project, to be located in an inactive underground mine adjacent to Morgan Creek near the City of Bishop in Inyo County, California.

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

The proposed project would consist of: an existing 12-foot-high by 12-foot-wide by 30-foot-thick reinforced concrete plug inside a 12,000-foot-long mine access tunnel capable of storing water up to 1,320 feet of gross head; a 200-acre-foot in-mine reservoir that backs up water inside the mine to a maximum elevation of 9,400 feet above sea level; a 24-inch or 18-inch steel penstock through the concrete plug connecting to a 1,500 kW impulse turbine; a 1.573 kilovolt-amp generator; and an approximately 2,500-foot-long transmission line connecting the generator to a substation. The estimated annual generation of the project would be 5,600 megawatt-hours.

The applicant contact is: Doug Hicks, 280 Floreca Way, Reno, Nevada  89511, phone (775) 997-3429.

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 Jan. 5 notice.
