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.

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.
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.

Regulated monopoly. Wyoming households buy both supply and delivery from their local regulated utility or co-operative; there is no competitive residential supplier market.
Where does this Wyoming rate figure come from?
It is the residential-sector average revenue per kilowatt-hour reported by utilities to the U.S. Energy Information Administration on Form EIA-861M and published in the Electric Power Monthly, Table 5.6.A. It blends supply and delivery across every residential customer in the state, so it is a statewide average rather than a quote for any individual household.
