PacifiCorp Project No. 15237-000
NOTICE OF PRELIMINARY PERMIT APPLICATION ACCEPTED FOR FILING AND SOLICITING COMMENTS, MOTIONS TO INTERVENE, AND COMPETING APPLICATIONS
(April 20, 2022)
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 Barn Canyon Pumped Storage Project to be located about 4 miles North of Helper, 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 with a surface area of 42 acres and a total storage capacity of 986 acre-feet at a normal maximum operating elevation of 8,355 feet average mean sea level (msl); (2) a new lower reservoir with a surface area of 28 acres and a total storage capacity of 1,664 acre-feet at a normal maximum operating elevation of 6,240 feet msl; (3) a 12,672-foot-long penstock, with a hydraulic head of 2,035 feet, connecting the upper and lower reservoirs to the powerhouse; (4) a new underground powerhouse that would be sited along the western shore of the lower reservoir containing three Francis turbine-generator units with a total rated capacity of 300 megawatts; (5) a new 10.2-mile-long, 345-kilovolt (kV) transmission line connecting the powerhouse to PacifiCorp’s existing Huntington-Spanish Fork substation constructed in 1979 for alternative 1; (6) a new 0.8-mile-long, 138-kV transmission line to interconnect the powerhouse to PacifiCorp’s existing Carbon substation for alternative 2; and (7) appurtenant facilities. The estimated annual power generation at the Barn Canyon Pumped Storage would be 624 gigawatt-hours.
