The Federal Energy Regulatory Commission on Sept. 18 went out for 60 days of public comment on a Sept. 4 application by White Pine Waterpower LLC for another preliminary permit on a 750-MW pumped storage hydro project in Nevada.
White Pine wants to, under a successive permit, continue to study the feasibility of the White Pine Pumped Storage Project, to be located near the town of Ely, White Pine County, Nev. 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. Other parties can submit a competing application during the 60-day comment period.
The proposed project would include: an artificially lined, upper reservoir having a capacity of 5,535 acre-feet at 8,550 feet above mean sea level (msl); an artificially lined, lower reservoir having a capacity of 5,535 acre-feet at 6,325 feet msl; a 350-foot-long by 100-foot-wide by 120-foot-high powerhouse located underground about 1,500 feet east of the lower reservoir at an elevation of around 6,000 feet msl; three 250 MW reversible pump-turbines, totaling 750 MW of capacity; and either a single-circuit 345-kV or double-circuit 230-kV transmission line extending approximately 1.1 mile in length to the Gondor substation, operated by Sierra Pacific Power and owned by Mt. White Power and partners in the Intermountain Power Project. The estimated annual generation of the project would be 1,970 gigawatt-hours.
Said the application: “The Project will be operated to provide firm capacity to the regional power grid and to support the integration of new renewable resources interconnected currently and in the future. These resources—predominantly wind and photovoltaic solar energy—are emissions-free and increase energy security, but are variable and intermittent in nature. The Project will use the dynamic capabilities of pumped storage to aid in the efficient integration of wind resources from both an operational and economic standpoint.”
