Pennsylvania Electricity Prices

Pennsylvania sits mid-pack — 21.55¢ per kilowatt-hour in May 2026, 16th-highest of 51 and 11.0% above the national benchmark.

At Pennsylvania's May 2026 average of 21.55¢/kWh, 10,500 kWh of annual use works out to $2,263 a year — around $189 a month. Running the same 10,500 kWh calculation at the May 2026 national benchmark rate gives $2,038 — a $225 gap between the two published averages, more for Pennsylvania, not a bill either way.

Over the full EIA series the Pennsylvania jurisdiction average has risen 147% since January 2001, from 8.74¢ to 21.55¢ in May 2026 — a compound 3.6% per year. The path has been unusually smooth — Pennsylvania is among the steadiest third of jurisdictions month to month.

Yes. The May 2026 average of 21.55¢ per kilowatt-hour is the highest monthly figure Pennsylvania has recorded across the EIA series, which begins in January 2001. The previous floor for the jurisdiction was 8.74¢ in January 2001.

June. Measured over the 25 complete calendar years the EIA series covers for Pennsylvania, 2001 through 2025, June runs highest relative to its own year and January runs lowest — a swing of roughly 9.4 percentage points.

Among Pennsylvania and its land-border neighbours in May 2026, Ohio posts the lowest average at 19.52¢ and New York the highest at 29.93¢. Pennsylvania ranks 2nd of 5 in the group, at 21.55¢.

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 Pennsylvania for May 2026 — a benchmark, never a billed amount. Even the jurisdiction figure is not one number — across the trailing year it moved between 19.51¢ in July 2025 and 21.55¢ 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.
