Methodology and sources

Data

Prices are the average price of electricity to ultimate customers by state and end-use sector, from the U.S. Energy Information Administration (EIA) Electric Power Monthly, Table 5.6.A (single month) and Table 5.6.B (year to date). Average monthly residential consumption and bills are from EIA Electric Sales, Revenue, and Average Price, Table 5A (2024). The current data release is October 23, 2026; EIA lists the next release as November 24, 2026.

EIA content is a U.S. government publication in the public domain. We show EIA's requested acknowledgment with the publication date on every page. We do not use the EIA logo, and this site is not affiliated with or endorsed by EIA.

Calculations

Energy used (kWh) = watts × hours per day × days ÷ 1,000. Cost = kWh × price in cents ÷ 100. "Estimated bill at the latest price" = the state's 2024 average monthly kWh (rounded) × the latest monthly residential price; it covers energy charges only. Percent change = (new − old) ÷ old × 100. Rank orders the 50 states and DC by residential price, highest first.

Limits

State averages hide large differences between utilities, rate plans, tiers, time-of-use pricing, fixed charges and taxes. Use the rate on your own bill for the most accurate answer. Values EIA marks as withheld, not meaningful or not available are shown as n/a.

How pages are produced and checked

A scheduled job downloads the EIA tables, rebuilds every page, and runs automated checks before publishing: every displayed number is recomputed from the source data, the calculator is unit-tested, near-duplicate or thin pages are blocked from search indexing, and source and disclosure text must be present. Pages that fail a check are published with a noindex tag and left out of the sitemap until they pass. No person writes or reviews individual state pages or monthly reports; the operator maintains the software and the checks. The guides were drafted with AI assistance; their figures are inserted from the data and verified by the same checks.
