In 2023, the “basic fuel mix,” the average mix of energy sources supplying Rocky Mountain Power customers, was 36.1% coal, 22.4% natural gas, 15.9% wind, 5.1% hydro, 6.3% solar, 0.4% geothermal, 0.4% biomass, 0.2% other and 13.3% unspecified. This information is based on Federal Energy Regulatory Commission Form 1 data. The Rocky Mountain Power “basic fuel mix” is based on energy production and not resource capability, capacity or delivered energy.

Rocky Mountain Power’s basic fuel mix includes owned resources and purchases from third parties. All or some of the renewable energy attributes associated with solar, wind, biomass, geothermal and hydro facilities in Rocky Mountain Power’s basic fuel mix may be: (a) used to comply with renewable portfolio standards or other regulatory requirements, (b) sold to third parties in the form of renewable energy credits and/or other environmental commodities or (c) not acquired. As of March 30, 2024, not counting compliance use, approximately 43% of the renewable energy attributes associated with 2023 generation and purchases was sold to third parties or not acquired. This includes all renewable energy attributes associated with customer-enabled renewable resources. This percentage may increase upon subsequent company sale of renewable energy certificates representing 2023 generation.

The average Rocky Mountain Power residential customer uses 758 kilowatt-hours per month.
