Wyoming Electricity Prices

Wyoming sits mid-pack — 14.80¢ per kilowatt-hour in May 2026, 38th-highest of 51 and 23.8% below the national benchmark.

At Wyoming's May 2026 average of 14.80¢/kWh, 10,500 kWh of annual use works out to $1,554 a year — around $130 a month. Running the same 10,500 kWh calculation at the May 2026 national benchmark rate gives $2,038 — a $484 gap between the two published averages, less for Wyoming, not a bill either way.

Over the full EIA series the Wyoming jurisdiction average has risen 146% since January 2001, from 6.01¢ to 14.80¢ in May 2026 — a compound 3.6% per year. Month-to-month movement has been about typical for a reporting jurisdiction.

October 2025, at 15.11¢ per kilowatt-hour. The May 2026 reading of 14.80¢ sits 2.1% below that peak. The lowest monthly average on record was 6.01¢ in January 2001.

September. Measured over the 25 complete calendar years the EIA series covers for Wyoming, 2001 through 2025, September runs highest relative to its own year and January runs lowest — a swing of roughly 16.3 percentage points.

Among Wyoming and its land-border neighbours in May 2026, Idaho posts the lowest average at 12.35¢ and Colorado the highest at 16.16¢. Wyoming ranks 4th of 5 in the group, at 14.80¢.

Almost certainly not exactly, and this is the one caveat that governs every figure on this page. The published value is the EIA residential average across every utility and residential rate class in Wyoming for May 2026 — a benchmark, never a billed amount. Even the jurisdiction figure is not one number — across the trailing year it moved between 12.83¢ in December 2025 and 15.11¢ in October 2025. Your own rate depends on your utility, tariff, usage tier, time-of-use schedule, and fixed monthly charges, none of which this index models. Read your bill for the rate that applies to you.
