Who generates Wyoming's electricity
Wyoming has 121 operable generating units on EIA's inventory totalling 11,801 MW of net summer capacity. The largest single plant is Jim Bridger , a natural gas steam turbine station operated by PacifiCorp , rated 2,119 MW.
Balancing authorities keep supply and demand matched on the grid; the largest here by capacity are PacifiCorp - East, Western Area Power Administration - Rocky Mountain Region and Western Area Power Administration UGP West.

What Wyoming's Electricity Data Tells Us
Residential customers in Wyoming pay 13.38¢/kWh in 2025, across 291.4K metered households, placing the state 22.7% below the national residential average of 17.30¢/kWh. Commercial rates sit at 9.54¢/kWh while industrial buyers pay 8.66¢/kWh. These sector averages describe recorded revenue per kWh; this dataset alone does not establish why they differ. Annual residential sales total 3.0M MWh on roughly $395.4M in utility revenue. Sales and revenue are reported retail-series measures and should not be treated as a local load forecast.
The two ends of Wyoming's market are priced very differently: 38 of 51 for households against 24 for industry. A gap this wide means a single statewide "electricity price" describes almost nothing, and the sector figures above should be read separately. Coal carries the majority of Wyoming's in-state generation at 58.9%, though not the whole grid: wind supplies 27.3% and natural gas a further 10.0%. It is the leading fuel in 9 states. Renewable fuels (solar, wind, hydro, geothermal and biomass) account for 30.8% of Wyoming's electricity output. These shares describe in-state generation, not a utility-specific customer bill.
Looking back across EIA records, residential prices in Wyoming moved from 11.13¢/kWh in 2016 to 13.38¢/kWh in 2025, a 20.2% shift over that window. States charging a similar rate include South Dakota, Missouri, Kentucky, a useful peer set for a sanity check. A coal-led grid prices differently from a fuel-market-led one. Wyoming's generators buy under multi-year contracts and recover plant capital through the rate base, so the rate above tends to move in regulated steps rather than with any commodity price, and the live question is what retiring units get replaced with. Read the number as a floor rather than a promise. A statewide average this far under the national figure is usually held down by a few large low-cost generators, and a household on the wrong side of a service-territory boundary in Wyoming can pay well above it.

Wyoming Average Price by Sector and Year (¢/kWh)
The chart above tracks households only. In 2025, Wyoming households paid 13.38¢/kWh while businesses paid 9.54¢/kWh, a 40.3% residential premium, a wider household-versus-business gap than most states.

Using Wyoming's numbers
Wyoming is mid-transition, which is the phase where prices are hardest to predict: it is paying to run the old fleet and to build the new one at the same time, and the rate above sits in the middle of that.
- Wyoming sits 22.7% below the national average, see exactly where it lands among all 50 states. See the rankings
- Check the multi-year trend before you judge the rate, a low price rising fast can cost more over a decade than a steady one. Wyoming price trend
- Compare Wyoming side by side with the US average and peer states using the tool above, then estimate your own bill from your monthly kWh. Cost calculator
Figures are EIA state averages by sector, computed as revenue divided by sales, so delivery and taxes are inside them but not broken out. Your actual rate depends on your utility, plan, and usage, see our disclaimer.
