The Federal Energy Regulatory Commission said Oct. 31 that it will take comment for 60 days on an Aug. 5 application from Hydro Green Energy LLC for a preliminary permit on a 1,270-MW pumped storage hydro project in California.
The Fort Ross Project is to be located near the town of Jenner, Sonoma County, Calif. The sole purpose of a preliminary permit, if issued, is to grant the permit holder priority to file a license application during the permit term. A license application would then be filed if the decision is to pursue development.
The proposed project would include:
- a 30-foot-high, 3,881-foot-long upper earthen embankment constructed with rubber sheet and asphalt lining;
- an upper reservoir having a total/usable storage capacity of 5,399 acre-feet at normal maximum operation elevation of 1,700 feet above mean sea level;
- four 19,000-foot-long by 10-foot-diameter steel lined penstocks connecting the upper reservoir to the Pacific Ocean;
- five 254-MW, reversible variable-speed pump-turbines;
- a new powerhouse and substation located about 100 feet below ground; and
- a new single-circuit 230-kV transmission line approximately 24.7 miles in length.
The estimated annual generation of the Fort Ross Project would be 3,714.4 gigawatt-hours.
The applicant contact is: Mark Stover, Hydro Green LLC, 900 Oakmont Lane, Suite 310, Westmont, IL 60559; phone: (877) 556-6566 ext. 709.
Hydro Green Energy on Aug. 7 filed at FERC a separate preliminary permit application on a second pumped storage hydro project along the California coast that would also use seawater. That application from project company HGE Energy Storage 1 LLC was for a 1,338-MW project in Santa Barbara County near Vandenberg Air Force Base. FERC on Oct. 31 sent the company a letter saying that the Aug. 7 application was deficient in terms of project maps and that updates needed to be filed within 30 days.
