Fort Ross Hydrokinetic – Pumped Storage Project

Pacific Ocean & Lands, Sonoma County, Fort Ross, California.

Project Profile & Applicant

FERC Project No.14543 is a proposed Hydrokinetic Pumped Storage Project to be located along the intertidal/nearshore and terrestrial lands in Sonoma County, near Fort Ross, California. This proposed 1,270 megawatt (MW) Project is owned by HGE Energy Storage 1, LLC (HGE; a subsidiary of Hydro Green Energy, LLC). The proposed Project would draw seawater from the intertidal zone and pump it up into a proposed land-based reservoir. Seawater would then be allowed to flow downhill back into the Pacific Ocean through a nearshore underground powerhouse to generate power. The proposed Project would consist of the following Facilities: 

An Intertidal Breakwater would create an Intertidal Pool from which a Vertical Intake would pump seawater 100 feet down into an underground Powerhouse/Tailrace. Seawater would be pumped through five Conduits/Penstocks about 19,000 feet uphill into a Land Reservoir (5,400 Acre-Feet) located at about 1,700 feet above mean sea level. Seawater in the Land Reservoir would then gravity-flow downhill through the five Conduits/Penstocks, through the five 254 MW Reversible Variable-speed Pump-turbines in the Powerhouse, and discharge through the Powerhouse/Tailrace back into the Breakwater Pool and the intertidal Pacific Ocean. A 24.7 mile long, 230 kilovolt, Transmission Line is proposed to connect the Powerhouse into a proposed AC/DC Substation.
