Oklahoma Electricity Prices

Relatively, yes — 13.38¢ per kilowatt-hour in May 2026, 3rd-cheapest of 51 and 31.1% below the national benchmark.

At Oklahoma's May 2026 average of 13.38¢/kWh, 10,500 kWh of annual use works out to $1,405 a year — around $117 a month. Running the same 10,500 kWh calculation at the May 2026 national benchmark rate gives $2,038 — a $633 gap between the two published averages, less for Oklahoma, not a bill either way.

Over the full EIA series the Oklahoma jurisdiction average has risen 105% since January 2001, from 6.53¢ to 13.38¢ in May 2026 — a compound 2.9% per year. Oklahoma is among the most month-to-month variable third of jurisdictions.

September 2025, at 14.79¢ per kilowatt-hour. The May 2026 reading of 13.38¢ sits 9.5% below that peak. The lowest monthly average on record was 5.65¢ in January 2002.

September. Measured over the 25 complete calendar years the EIA series covers for Oklahoma, 2001 through 2025, September runs highest relative to its own year and January runs lowest — a swing of roughly 24.8 percentage points.

Among Oklahoma and its land-border neighbours in May 2026, Oklahoma posts the lowest average at 13.38¢ and Texas the highest at 16.44¢. That makes Oklahoma the cheapest in the group, at 13.38¢.

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 Oklahoma for May 2026 — a benchmark, never a billed amount. Even the jurisdiction figure is not one number — across the trailing year it moved between 12.25¢ in December 2025 and 14.79¢ in September 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.
