Colorado Electricity Prices

Colorado sits mid-pack — 16.16¢ per kilowatt-hour in May 2026, tied 28th-highest of 51 and 16.7% below the national benchmark.

At Colorado's May 2026 average of 16.16¢/kWh, 10,500 kWh of annual use works out to $1,697 a year — around $141 a month. Running the same 10,500 kWh calculation at the May 2026 national benchmark rate gives $2,038 — a $341 gap between the two published averages, less for Colorado, not a bill either way.

Over the full EIA series the Colorado jurisdiction average has risen 141% since January 2001, from 6.71¢ to 16.16¢ in May 2026 — a compound 3.5% per year. The path has been unusually smooth — Colorado is among the steadiest third of jurisdictions month to month.

February 2026, at 16.79¢ per kilowatt-hour. The May 2026 reading of 16.16¢ sits 3.8% below that peak. The lowest monthly average on record was 6.71¢ in January 2001.

September. Measured over the 25 complete calendar years the EIA series covers for Colorado, 2001 through 2025, September runs highest relative to its own year and January runs lowest — a swing of roughly 10.6 percentage points.

Among Colorado and its land-border neighbours in May 2026, Utah posts the lowest average at 12.96¢ and Colorado the highest at 16.16¢. That makes Colorado the most expensive in the group, at 16.16¢.

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 Colorado for May 2026 — a benchmark, never a billed amount. Even the jurisdiction figure is not one number — across the trailing year it moved between 15.99¢ in July 2025 and 16.79¢ in February 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.
