Cost to Heat a Home in Wyoming: Gas vs Propane vs Heat Pump

In Wyoming the cheapest heat last winter was natural gas at $12.63 per MMBtu delivered; electric resistance cost $39.71 — EIA prices, October 2025 to March 2026.

Wyoming heating cost per MMBtu, fuel by fuel

The season column is an illustrative 60 MMBtu of delivered heat; in Wyoming that puts natural gas at $758 and electric resistance at $2,383 for the winter. The this-winter column applies EIA’s national STEO change per fuel to Wyoming’s own price (electricity +3%) — direction, not a state forecast.

The prices behind the table

Wyoming’s June gas figure ($18.28/Mcf) runs 1.5× its winter average ($12.46) because EIA’s residential price is average revenue per Mcf with the fixed charge folded in; the high-volume winter months are the closest published proxy for the marginal rate this page needs.

What Wyoming’s utilities charge

The statewide 13.55¢ hides a 3.6¢ spread between Wyoming’s largest utilities, worth $10.55 per MMBtu on resistance heat and $4.86 on a heat pump. The ZIP lookup finds yours.

How Wyoming homes are heated

Natural gas heats 59.4% of Wyoming’s 238,176 occupied homes against 46.8% nationally, with electricity at 23.3%, propane at 11.0% and heating oil at 0.1%. That lines up with the table above: natural gas was also Wyoming’s cheapest heat last winter at $12.63 per MMBtu.

What the numbers say about Wyoming

At last winter’s average prices, the cheapest way to heat a home in Wyoming was natural gas at about $13 per million Btu delivered, and the most expensive was electric resistance at $40 — a 3.1× spread between the two columns. Gas beat a cold-climate heat pump at 17°F (COP 2.17) by $5.67/MMBtu, and at 47°F (COP 3.2, $12.41) the heat pump pulls ahead. At Wyoming’s winter rates the economic balance point lands about 45°F (COP 3.14 needed). No EIA state or regional heating-oil series exists for Wyoming; the oil row is the national STEO average ($3.94/gal last winter, $5.30 forecast) and is labelled as such. Propane is the Rocky Mountain (PADD 4) regional figure of $2.19/gal, since SHOPP has no Wyoming series.

Heating degree-days: Wyoming’s own figure and the EIA division forecast

Wyoming itself logged 5,222 population-weighted heating degree-days from October 2025 to March 2026 (NOAA Climate Prediction Center state series, base 65°F), against 3,500 for the contiguous US. The month-by-month table below is a different, coarser series — EIA STEO Mountain census division degree-days, the only one with a forecast for the coming winter; it groups Wyoming with its neighbours and is not a Wyoming figure:

January in the EIA Mountain census division (the coarse series that groups Wyoming with its neighbours) averaged about 39°F last winter (65°F minus degree-days per day) and is forecast at 37°F for January 2027, a season move of +791 degree-days. Degree-days set how much heat Wyoming needs, the table above sets the price per unit, and the bill jump calculator multiplies the two.

Where the heat pump crosses over in Wyoming

At last winter’s averages of 13.55¢/kWh and $1.20/therm, a heat pump beats a 95% gas furnace whenever its COP exceeds 3.14. Wyoming’s economic balance point on the NEEP median curve is about 45°F (COP 3.14 needed); the crossover tool runs seven named units at Wyoming’s prices and the dual-fuel calculator turns the answer into a changeover setting.

From October 6 the EIA Winter Fuels Outlook adds household expenditure by region and the weekly SHOPP survey restarts, giving Wyoming fresh regional propane readings on the weekly tracker .
