Average price = residential revenue ÷ residential sales from each utility's federal EIA-861 filing (bundled service — supply + delivery + riders, not a quoted tariff rate). State average = 12.11¢/kWh, volume-weighted across these utilities (2024). Your distribution utility is fixed by address; these gaps measure what households in different territories actually paid.

How to switch suppliers in Wyoming (3 steps)
- Find the price to compare (default supply rate) on your utility bill — you only save when an offer beats it for the same period.
- Compare licensed supplier offers on the state's official shopping site: psc.wyo.gov. Check term, early-exit fees, and whether the rate is fixed or variable.
- Sign up with the supplier — they handle the switch. Your utility still delivers the power, owns the wires, and responds to outages; only the supply line of the bill changes.
Heating: which fuel is cheapest per million BTU in Wyoming?
| Fuel | Native price | As of | $ per MMBTU |

Utility natural gas is the cheapest residential energy per BTU in Wyoming at $9.56/MMBTU. Conversions: 1 kWh = 3,412 BTU; 1 therm = 100,000 BTU; heating oil 138,500 BTU/gal; propane 91,452 BTU/gal. Site-energy prices — appliance efficiency changes delivered-heat cost: a 95% AFUE gas furnace delivers heat near the gas figure, while a heat pump at seasonal COP 2.5–3 cuts the effective electric figure by 60–70%.
