PurposeThe primary purpose of the Spirit Mountain Powerplant is to dissipate energy of the water from the pressurized supply conduit from Buffalo Bill Reservoir before it enters the unpressurized supply canal which feeds the Heart Mountain Powerplant and the Heart Mountain Canal. The secondary purpose of the powerplant is to produce electrical power.
FactsSpirit Mountain Powerplant consists of one 4,500-kilowatt generator.
HistoryOperation of this plant began in October, 1994.
Special IssuesThis plant cannot operate unless the downstream Shoshone conduit is watered up. As a result of the modification of Buffalo Bill Dam, Buffalo Bill and Shoshone Powerplants were completed in 1992. Due to the Revised Instream Flow Agreement associated with the reconstruction of the dam, winter releases previously discharged from Heart Mountain Powerplant that would have passed through spirit Mountain Powerplant are now made through the two upstream facilities. As a result, Spirit Mountain Powerplant has been operated on a seasonal basis since its completion in 1995.
