Electricity rates in Wyoming

Not a state average. The same household, priced hour by hour for a year on the default plan at each utility we cover here — so the differences below are differences in the tariffs, not in how much anyone used.

Median and range across the 2 utilities, each on the plan a household lands on by default. Estimates for comparing utilities against each other, not a prediction of any one bill; they exclude taxes, local surcharges and demand charges.

How much does where you live inside Wyoming matter?

Run the same three-bedroom house with central air through the default residential plan at each of the 2 utilities we cover in Wyoming, and the yearly bill lands between $1,308 at PacifiCorp and $1,467 at High West Energy; the median is $1,387. That is a narrow band — the dearest utility charges 12% more than the cheapest for identical use. In Wyoming, who bills you matters less than how much you use and which of their plans you are on.

The utility is fixed by your address; the plan is not. At PacifiCorp, the cheapest and dearest of its 2 comparable plans are $124 a year apart for the same house — less than the gap between utilities, but it is the one lever that is actually yours to pull.

Every one of these utilities files at least one plan priced by the hour — 2 such plans in all. That makes Wyoming a place where moving laundry, dishes or car charging into the cheap window changes the bill, provided you are on one of those plans; on a flat plan the clock is irrelevant.

Utility by utility

Cheapest first, for the family home. The last two columns are where the money is: how far the default plan sits from the cheapest one the same utility files.

Default plan is the one a household is put on without choosing; we infer it from the tariff structure, since the source data flags it for only 3% of plans. Where a utility splits its territory into rate zones, the figures are for its largest zone and the cheapest plan is the cheapest in that same zone.
