Both the lower usage and the substantially lower rate pull the state well below the national bill.

How this is calculated

EIA’s retail-sales dataset reports, for every state and month, total residential revenue and the number of residential customers served. The average monthly bill is simply the first divided by the second — total spending across all households, spread evenly over all accounts.

bill = revenue ÷ customers · averaged over 12 months (June 2025 – May 2026)

Two caveats worth knowing. It is an average, so it blends apartments with large houses — a typical household in Wyoming may pay well above or below $114. And it counts what was actually billed for electricity, including fixed service charges, so it is not the same as multiplying your own usage by the advertised rate.
