This is an estimate of the fuel mix of Idaho Power’s portfolio of generation supply, including market purchases. In the case of market purchases, it is not always possible to precisely determine the source of the generation.
With 17 low-cost hydroelectric projects at the core of our generation portfolio, water is one of Idaho Power’s most important fuels. Year-to-year variability in snowpack and the resulting Snake River flows have a significant impact on Idaho Power’s fuel mix.
In low water years, our fuel mix will most likely contain higher percentages of natural gas and coal-fired generation and purchases. In high water years, the percentage of hydroelectric generation will increase.
