Electricity Rates in Wyoming (2026)
National average: 16.72¢/kWh · Source: EIA, January 2026
Wyoming Has Some of the Cheapest Electricity in the Nation
At 11.23 cents/kWh, Wyoming ranks among the five cheapest states for electricity. The state has massive coal reserves (it is the largest coal-producing state in the U.S.) and exceptional wind resources. Rocky Mountain Power and Black Hills Energy serve most of the state. Coal generates about 70% of Wyoming's electricity, with wind providing an increasing share (about 20%).
Wyoming's Wind Potential Is Among the Best in the World
Wyoming has the strongest sustained winds of any state, particularly across the southern and central plains. The state exports wind-generated electricity to neighboring states and is a key hub for the transmission of wind power to California and the Pacific Northwest. New transmission projects (like the Gateway West line) will further expand Wyoming's role as a wind energy exporter.

Frequently Asked Questions About Wyoming Electricity
Wyoming is the largest coal-producing state in the U.S., and proximity to the mines keeps fuel transportation costs minimal. The state also has world-class wind resources that are being developed at scale. This combination of cheap coal and zero-fuel-cost wind keeps generation costs among the lowest in the nation.
The average Wyoming household pays about $95-$120 per month. Very low rates keep bills down despite cold winters that drive heating demand. Many Wyoming homes heat with natural gas or propane. The sparse population and large distances between communities do not significantly increase distribution costs because the same cooperative model that serves rural areas keeps overhead low.
