New Jersey Electricity Prices

New Jersey sits mid-pack — 23.27¢ per kilowatt-hour in May 2026, 13th-highest of 51 and 19.9% above the national benchmark.

At New Jersey's May 2026 average of 23.27¢/kWh, 10,500 kWh of annual use works out to $2,443 a year — around $204 a month. Running the same 10,500 kWh calculation at the May 2026 national benchmark rate gives $2,038 — a $405 gap between the two published averages, more for New Jersey, not a bill either way.

Over the full EIA series the New Jersey jurisdiction average has risen 142% since January 2001, from 9.62¢ to 23.27¢ in May 2026 — a compound 3.5% per year. Month-to-month movement has been about typical for a reporting jurisdiction.

July 2025, at 25.32¢ per kilowatt-hour. The May 2026 reading of 23.27¢ sits 8.1% below that peak. The lowest monthly average on record was 9.34¢ in February 2001.

August. Measured over the 25 complete calendar years the EIA series covers for New Jersey, 2001 through 2025, August runs highest relative to its own year and January runs lowest — a swing of roughly 11.2 percentage points.

Among New Jersey and its land-border neighbours in May 2026, Delaware posts the lowest average at 19.38¢ and New York the highest at 29.93¢. New Jersey ranks 3rd of 4 in the group, at 23.27¢.

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 New Jersey for May 2026 — a benchmark, never a billed amount. Even the jurisdiction figure is not one number — across the trailing year it moved between 22.55¢ in October 2025 and 25.32¢ in July 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.
