Hooper Springs Transmission Project, Caribou County, Idaho
BPA intends to prepare an EIS in accordance with the National Environmental Policy Act (NEPA) on the proposed construction, operation, and maintenance of a 115-kilovolt (kV) transmission line and a 138/115-kV substation (collectively referred to as the Hooper Springs Project). The new BPA substation would be called Hooper Springs Substation and would be located adjacent to PacifiCorp's existiog 345/138-kV Threemile Knoll Substation, located near the City of Soda Springs in Caribou County, Idaho. The new 115-kV single-circuit BP A transmission line would exlend generally north and east from these substations to a connection with Lower Valley Energy's (L VE's) existing 115-kV Lane Creek Substation, east of the City of Wayan, Idaho. The proposed project would address voltage stability and reliability concerns of two of BPA's full requirements customers, L VE and Fall River Rural Electric Cooperative (Fall River), which purchase all or almost all of the electric power required to serve their loads from BPA under existing contracts.
