Hydroelectricity

IPC's 17 hydroelectric power plants have a generation nameplate capacity of 1,988,615 kilowatts, and it is one of the nation's few investor-owned utilities with a significant hydroelectric generating base. Four-fifths of Idaho’s electricity generation is from hydroelectric. Idaho Power built the majority of its hydroelectric facilities during the 1940s, 1950s and 1960s, culminating with completion of the three-dam Hells Canyon Complex (Brownlee Dam, Oxbow Dam, then Hells Canyon Dam) in 1968.
