          - [Project No. 15243-000]

On October 13, 2021, PacifiCorp filed an application for a preliminary permit, pursuant to section 4(f) of the Federal Power Act (FPA), proposing to study the feasibility of Rock Canyon Pumped Storage Project to be located in Emery county, Utah. 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 project would consist of the following: (1) A new upper reservoir for alternative 1 with a surface area of 48.2 acres and a total storage capacity of 1,902.8 acre-feet at a normal maximum operating elevation of 8,380 feet average mean sea level (msl); (2) a new upper reservoir for alternative 2 with a surface area of 87 acres and a total storage capacity of 2,083 acre-feet at a normal maximum operating elevation of 8,600 feet msl; (3) a new lower reservoir for alternatives 1 and 2 with a surface area of 72 acres and a total storage capacity of 3,119 acre-feet at a normal maximum operating elevation of 6,300 feet ms); (4) a 3,696-foot-long tunnel and 12,672-foot-long penstock, with a hydraulic head of 2,470 feet, connecting the upper and lower reservoirs to the powerhouse for alternative 1; (5) a 10,032-foot-long tunnel penstock, with a hydraulic head of 2,250 feet, connecting the upper and lower reservoirs to the powerhouse for alternative 2; (6) a new underground powerhouse that would be sited along the western shore of the lower reservoir for alternatives 1 and 2 containing three turbine-generator units with a total rated capacity of 500 megawatts; (7) a new 5-mile-long, 345-kilovolt (kV) transmission line connecting the powerhouse to PacifiCorp's existing Emery substation for alternatives 1 and 2; and (8) appurtenant facilities. The estimated annual power generation at the Rock Canyon Pumped Storage would be 1,460 gigawatt-hours.
