Charging an electric car in Wyoming
Driving a Tesla Model Y Long Range AWD 1,000 miles a month takes 275 kWh from the wall (EPA 27.5 kWh/100 mi), about $39 at the state average. A 25.5 mpg gasoline car covering the same distance at $4.45 a gallon (Rocky Mountain (PADD 4) average, October 2026) costs about $174.
On a time-of-use plan, charging in the cheapest hours beats the flat average. The table shows, for each utility, the plan with the lowest total bill for a typical Wyoming home that adds 1,000 EV miles a month, averaged over the year, and what plugging in at 6 pm would cost instead.
| Utility | Best plan for an EV | Best start | 1,000 mi, best start | From 6 pm |

The state average hides the real spread. Utilities in the same state charge different prices, and on a time-of-use plan the same kWh costs more in the peak hours than off-peak; each utility page shows by how much.

Natural gas for homes averaged $1.24 per therm over the 12 months to July 2026 (EIA, all charges included), and a typical gas-heated home uses about 645 therms a year for heating. The heat pump calculator compares that with electric heating on your plan.
A south-facing, 20° rooftop array in Wyoming produces about 1,556 kWh per installed kW a year (NREL PVWatts at the state’s population center). What that is worth depends on your utility’s export rule, shown on each utility’s page.
