Green Energy Storage seeks permit on pumped storage/solar project

Green Energy Storage Corp. (GESC) applied April 3 at the Federal Energy Regulatory Commission for a preliminary permit for the proposed Weed Heights Pumped Storage project, which would consist of 150 MW of hydro and 100 MW of solar generation in Nevada.

This application was made in order that the applicant can secure and maintain priority of application for a license for this project during the three-year term of a preliminary permit.

The project site is in Lyon County, Nev. This project will consist of a 150-MW closed-loop pumped storage facility and a 100-MW solar plant. Both are to be located at an existing open pit mine with the pump storage plant utilizing an existing 800 foot deep open pit mine for the lower reservoir and an adjacent waste-rock dump for the upper reservoir locations. The 100-MW solar-panel plant is to be built adjacent to the upper reservoir, on top of the existing waste rock dump.

The upper reservoir dam will be 35 feet high with a total crest length of 8,000 feet. The reservoir will have a surface area of 75 acres with an impoundment of 2,600 acre-feet. The lower reservoir will not require a dam as it will be located in the bottom of an existing open pit mine.

Located in the powerhouse will be two 75-MW pump/turbine units, associated switchgear, and controls.

The tentative proposed transmission line interconnect site is at an existing 120-kV transmission line owned by Sierra Pacific Power. This will require new 120-kV transmission lines extending some seven miles from a new 200 MVA substation located adjacent the upper reservoir, to the interconnect site.

  • FERC on March 18 received a preliminary permit application from GESC for a 150-MW pumped storage hydro project in Arizona that would also include a 100-MW solar facility. The Ajo Pumped Storage Project would be located in Pima and Maricopa counties.
  • GESC applied Feb. 24 at the commission for a preliminary permit for the proposed Sacaton Pumped Storage Project in Arizona. This project, located in Pinal County, will consist of a 150-MW closed-loop pumped storage facility and a 100-MW solar plant.
