Wisconsin Electricity Prices

Wisconsin sits mid-pack — 19.74¢ per kilowatt-hour in May 2026, 17th-highest of 51 and 1.7% above the national benchmark.

At Wisconsin's May 2026 average of 19.74¢/kWh, 10,500 kWh of annual use works out to $2,073 a year — around $173 a month. Running the same 10,500 kWh calculation at the May 2026 national benchmark rate gives $2,038 — a $35 gap between the two published averages, more for Wisconsin, not a bill either way.

Over the full EIA series the Wisconsin jurisdiction average has risen 165% since January 2001, from 7.46¢ to 19.74¢ in May 2026 — a compound 3.9% per year. The path has been unusually smooth — Wisconsin is among the steadiest third of jurisdictions month to month.

Yes. The May 2026 average of 19.74¢ per kilowatt-hour is the highest monthly figure Wisconsin has recorded across the EIA series, which begins in January 2001. The previous floor for the jurisdiction was 7.46¢ in January 2001.

September. Measured over the 25 complete calendar years the EIA series covers for Wisconsin, 2001 through 2025, September runs highest relative to its own year and January runs lowest — a swing of roughly 7.9 percentage points.

Among Wisconsin and its land-border neighbours in May 2026, Iowa posts the lowest average at 14.14¢ and Illinois the highest at 23.85¢. Wisconsin ranks 3rd of 5 in the group, at 19.74¢.

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 Wisconsin for May 2026 — a benchmark, never a billed amount. Even the jurisdiction figure is not one number — across the trailing year it moved between 17.84¢ in December 2025 and 19.74¢ in May 2026. 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.
