Electricity Rate Increases by State
Realized rates through May 2026 (the latest month EIA has published) · Updated August 18, 2026
As of May 2026, the average U.S. residential electricity rate is 18.44¢/kWh, +6.2% (+1.07¢) from a year earlier, per EIA monthly retail sales data. The fastest-rising states over the last 12 months are Illinois (+28.4%), Hawaii (+26.7%), District of Columbia (+24.3%). The rate-case ledger below tracks 11 requested and 12 approved major rate cases (plus 1 settled and awaiting commission approval); the counts are never summed, because a request is not an approval.
These are realized average effective rates (all charges included, revenue ÷ sales), so they capture everything that actually moved bills: base-rate cases, riders, fuel adjustments and, in retail-choice states, supply prices. For why rates are rising, see Why is my electric bill so high? For the level rather than the change, see electricity rates by state or look up your own utility by ZIP code.

Source: EIA, Electricity Data Browser (retail sales, residential sector, monthly). Rate = residential revenue ÷ residential sales for the month shown; changes compare the same calendar month, so seasonality does not distort them. EIA publishes with a ~2-month lag and revises recent months; revisions are logged on the data updates page.
Major rate cases: requested vs approved
Docket-linked ledger of major rate cases. Requested, approved and implemented are different things and are never summed. A "$500M rate increase" headline is a revenue requirement; the consumer-relevant number is dollars per month on a typical residential bill, shown here alongside the utility's own figure. Every row links its primary source (PUC docket or the utility's filing).

Frequently asked questions
Which states had the biggest electricity rate increases in the last year?
Over the 12 months through May 2026, the largest residential rate increases were in Illinois (+28.4%), Hawaii (+26.7%), District of Columbia (+24.3%), per EIA monthly retail sales data. The ranked table above covers all 50 states and DC.
Why did my electric bill go up if my utility didn't announce a rate increase?
Base rates are only one piece of a bill. Riders and surcharges, fuel or purchased-power adjustment clauses, and, in retail-choice states, supply prices can all move a bill without a headline rate case. The figures on this page are average effective rates (revenue ÷ sales), so they capture all of those together. The drivers are covered on Why is my electric bill so high?
How current are these numbers?
EIA publishes monthly retail data about two months after the fact; this page shows data through May 2026 and states that month wherever a figure appears. We never project unpublished months, and EIA's revisions are logged on the data updates page.
Are these rates the same as my tariff?
No. These are average effective prices: everything residential customers paid divided by the kWh they used, including fixed charges, riders and taxes collected through rates. Your tariff's marginal price will differ. For your own utility's average, use the ZIP code lookup.
What is the difference between a requested and an approved rate increase?
A utility files a request; the state commission decides. Settlements and final orders routinely cut requested amounts substantially, so summing requested with approved dollars overstates what customers will pay. This page always reports the two separately, and a row moves from requested to approved only when the commission issues its decision.
How does Texas fit in, with its deregulated market?
In most of Texas, the regulated rate case applies to the delivery utility (Oncor, CenterPoint and others), while the supply price comes from competitive retail providers. Texas ledger rows are delivery-charge cases and are labeled as such.
Methodology
Rate changes are computed from EIA's monthly retail sales series (residential sector): average effective rate = revenue ÷ sales, compared against the same calendar month 1, 3 and 5 years earlier. This is the all-in average price customers actually paid, not a tariff rate. EIA publishes with a roughly 2-month lag; this page always states its data month and never projects unpublished months. The rate-case ledger covers PUC-regulated investor-owned utilities of any size plus non-regulated utilities (municipal, cooperative, public power) with roughly 250,000 or more customers; every row is verified against the docket or the utility's primary filing before publication.
