FERC issues two preliminary permits to Premium Energy Holdings

The Federal Energy Regulatory Commission has issued two preliminary permits to Premium Energy Holdings LLC to study the feasibility of the 2,000-MW Pyramid Lake Pumped Storage Project in Washoe County, Nevada, and the Haiwee Pumped Storage Project (capacity 1,600 MW to 2,000 MW) in Inyo County, Calif.

The proposed Pyramid Lake project would consist of the existing Pyramid Lake (storage capacity 23.6 million acre-feet) as the lower reservoir and the proposed San Emidio Reservoir (storage capacity 21,550 acre-feet), Tohakum Peak Reservoir (storage capacity 27,050 acre-feet) or Lake Range Reservoir (storage capacity 26,020 acre-feet) as the upper reservoir. All three would be built and would be located in the Lake Range east of Pyramid Lake.

The proposed project would also include an underground powerhouse 500 feet long by 85 feet wide by 160 feet high containing five 400-MW pump-turbine units. And a new, 15-mile-long 500-kV transmission line would be built to deliver power generated to the grid. The project will occupy Pyramid Lake Indian Reservation and U.S. Department of the Interior, Bureau of Land Management lands and have an estimated average annual generation of 6,900 GWh.

Premium Energy filed the application in June 2019 and requested a permit term of 24 months. The preliminary permit is effective March 1, 2020, and lasts for 24 months.

The proposed Haiwee project would consist of building a new North Haiwee 2 lower reservoir with a storage capacity of 38,350 acre-feet and the proposed McCloud Reservoir (storage capacity 44,554 acre-feet), Little Cactus Reservoir (storage capacity 47,021 acre-feet) or Haiwee Canyon Reservoir (storage capacity 28,620 acre-feet) as the upper reservoir. All three would be built.

The proposed project would also include an underground powerhouse 585 feet long by 90 feet wide by 165 feet high containing five 400-MW pump-turbine units. And a new, 2.5-mile-long 230-kV or 500-kV transmission line would be built to deliver power generated to the grid. The project will occupy Los Angeles Department of Water and Power and U.S. Department of the Interior, Bureau of Land Management lands and have an estimated average annual generation of 6,900 GWh.

Premium Energy filed the application in July 2019 and requested a permit term of 24 months. The preliminary permit is effective March 1, 2020, and lasts for 24 months.

The purpose of a preliminary permit is to preserve the right of the permit holder to have the first priority in applying for a license for the project that is being studied.

Earlier this month, we reported that Premium Energy Holdings also received a FERC preliminary permit to study feasibility of the 2,000-MW Walker Lake Pumped Storage Project in Nevada.
