          - [Project No. 15248-000]

      ( print page 66442)    
On November 18, 2021, RAMM Power Group LLC, filed an application for a preliminary permit, pursuant to section 4(f) of the Federal Power Act (FPA), proposing to study the feasibility of the Sacaton Energy Storage Project (Sacaton Project or project) to be located in Pinal County, Arizona. 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 preliminary permit does not authorize the permit holder to perform any land-disturbing activities or otherwise enter upon lands or waters owned by others without the owners' express permission.

The proposed 150-megawatt (MW) closed-loop pumped storage project would consist of the following: (1) an existing 1200-foot-deep open pit mine for the lower reservoir, which will have a storage capacity of 1,500 acre-feet at a maximum water surface elevation of 455 feet above mean sea level (msl); (2) an adjacent waste-rock dump for the upper reservoir, which will have a storage capacity of 1,300 acre-feet at a maximum water surface elevation of 1,456 feet msl; (3) a new 28-foot-high, 6,000-foot long upper reservoir dam; (4) a single 200-foot-long, 12-foot-diameter steel penstock connecting the upper and lower reservoirs; (5) a new underground powerhouse with two 75-MW pump/turbine generating units; (6) a single 14-foot-dimeter low-pressure draft tube that would extend approximately 2,200 feet from the powerhouse to the lower reservoir; (7) a new 200-megavolt-ampere substation located adjacent to the upper reservoir; and (8) a new 2,500-foot-long, 137-kilovolt transmission line connecting the new substation to the grid interconnection at a transmission line owned by Arizona Public Service. Initial fill water for the project would come from the mine and purchased from existing water rights holders. The proposed project would have an estimated average annual generation of 400,000 megawatt-hours.
