Maryland Electricity Prices

Maryland sits mid-pack — 21.77¢ per kilowatt-hour in May 2026, 15th-highest of 51 and 12.2% above the national benchmark.

At Maryland's May 2026 average of 21.77¢/kWh, 10,500 kWh of annual use works out to $2,286 a year — around $191 a month. Running the same 10,500 kWh calculation at the May 2026 national benchmark rate gives $2,038 — a $248 gap between the two published averages, more for Maryland, not a bill either way.

Over the full EIA series the Maryland jurisdiction average has risen 223% since January 2001, from 6.74¢ to 21.77¢ in May 2026 — a compound 4.7% per year. Maryland is among the most month-to-month variable third of jurisdictions.

March 2026, at 35.85¢ per kilowatt-hour. The May 2026 reading of 21.77¢ sits 39.3% below that peak. The lowest monthly average on record was 6.74¢ in January 2001.

June. Measured over the 25 complete calendar years the EIA series covers for Maryland, 2001 through 2025, June runs highest relative to its own year and January runs lowest — a swing of roughly 10.8 percentage points.

Among Maryland and its land-border neighbours in May 2026, West Virginia posts the lowest average at 16.80¢ and Maryland the highest at 21.77¢. That makes Maryland the most expensive in the group, at 21.77¢.

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 Maryland for May 2026 — a benchmark, never a billed amount. Even the jurisdiction figure is not one number — across the trailing year it moved between 18.83¢ in July 2025 and 35.85¢ in March 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.
