Why Wyoming pays what it pays

Wyoming produces more coal than any other state and burns some of it in plants built at the mine. Fuel transport cost, usually the largest component of delivered coal price, is close to zero. The plants are old and largely depreciated, and the state has added substantial wind with among the highest capacity factors in North America.

Against that, Wyoming has fewer than six hundred thousand residents spread across the ninth-largest land area in the country. Every mile of distribution line serves very few customers, so fixed costs per customer are high. That is why Wyoming is not as cheap as its generation position alone would suggest.

Its utility is part of a multi-state system, and Wyoming regulators have periodically fought over how much of that system's clean-energy transition costs Wyoming ratepayers should carry, given that the policies driving them were set in other states.

Where Wyoming power comes from

Wyoming generated 46 TWh in 2025, the 32th largest output of any state. Coal supplied 58.5% of it, enough that the price of that fuel largely sets the price of electricity here. Renewables accounted for 30.5%, against 23.8% nationally, which ranks Wyoming #20 of 51.

Net generation by fuel, 2025
  • Coal 27 TWh
  • Wind 13 TWh
  • Natural gas 5 TWh
  • Hydroelectric 1 TWh
  • Solar 496 GWh
  • Other 450 GWh

What Wyoming households actually pay

Average monthly bill $114 -27.0% vs the U.S. average of $155
Average monthly usage 810 kWh · U.S. average 871
Bill rank #46 of 51 · rate rank #38
Bill year over year +2.3% from $111 the year before

Wyoming looks more expensive on paper than it is in practice. Its rate ranks #38 of 51, but the average bill ranks only 46th, because households there use 810 kWh a month against a national average of 871. See how every state compares on bills.

Heating in Wyoming: gas, heat pump or resistance

Residential natural gas in Wyoming averaged $12.39 per thousand cubic feet in 2024, about $1.20 per therm, against a national average of $14.50. Put on the same scale as the state's electricity rate, the cost of delivering one million BTU of heat works out as follows.

Gas furnace $13.28 at 90% efficiency
Heat pump $14.46 at a seasonal COP of 3
Electric resistance $43.37 baseboard, wall or electric furnace

In Wyoming, gas remains cheaper to run than a heat pump by about $1.18 per million BTU at these assumptions, roughly $71 over a 60 million BTU season. A heat pump can still be the better purchase once cooling, equipment age and incentives are counted, but not on heating cost alone.

What each Wyoming utility charges

The statewide average hides a wide spread. Across the 9 Wyoming utilities reporting to the EIA, rates run from 6.44¢ at Lower Valley Energy Inc to 16.96¢ at Cheyenne Light Fuel & Power . Together they serve 245,377 residential customers.

Who sells electricity in Wyoming

Rocky Mountain Power, a PacifiCorp company, serves most of the state. Black Hills Energy covers the northeast and Montana-Dakota Utilities parts of the north. Co-operatives serve much of the land area, many supplied by Basin Electric.

There is no residential retail choice. The Wyoming Public Service Commission sets rates.

Wyoming sits in The Mountain West. Cheap legacy coal and abundant sun, with costs decided by how fast each state is retiring one and building the other. Read the regional analysis.

What you can actually do about it

Wyoming's fixed monthly charge is a substantial share of a typical bill, which reduces the return on usage-side efficiency relative to lower-fixed-charge states.

The multi-state allocation question is the main uncertainty in Wyoming's rate path. Watch PacifiCorp's protocol proceedings rather than individual rate cases.

Closest states by price

These jurisdictions charge within a fraction of a cent of Wyoming, which is useful if you are comparing a move or a multi-state operating cost.

Wyoming electricity rates: common questions

What is the average electricity rate in Wyoming?

The average residential electricity rate in Wyoming is 14.80 cents per kilowatt-hour as of May 2026, according to the U.S. Energy Information Administration. That is -19.7% relative to the national average of 18.44¢/kWh.

How much is the average monthly electric bill in Wyoming?

The average Wyoming household paid $114 a month across the twelve months to May 2026, using an average of 810 kWh. That is -27.0% against the U.S. average bill of $155, and it ranks 46th highest of the 51 jurisdictions. Your own bill depends on the size of your home, your heating and cooling equipment and your rate schedule.

Why is the Wyoming bill ranking different from its rate ranking?

A bill is the rate multiplied by usage, and usage varies between states more than price does. Wyoming ranks #38 of 51 on price but 46th on the actual bill, because households there use about 810 kWh a month against a national average of 871. Climate and heating fuel drive most of that difference.

Have electricity rates in Wyoming gone up?

Wyoming rates rose 7.1% over the year to May 2026, from 13.82¢ in May 2025 to 14.80¢.

Can I choose my electricity supplier in Wyoming?

Regulated monopoly. Wyoming households buy both supply and delivery from their local regulated utility or co-operative; there is no competitive residential supplier market.
