JSON API and widget
The API returns the same numbers as the pages without a key: rates with history at /api/v1/rates and appliance running costs at /api/v1/cost. The rates response includes a freshness block with the data month and the last source checks. The OpenAPI description lists every appliance and state it accepts. For a live figure on your own page, use the running-cost widget.
What you may reuse
The electricity rates are U.S. government data. The EIA states on its copyright and reuse page that its data are in the public domain, and asks for an acknowledgment that includes the publication date. Our calculations, charts and text can be quoted and linked with credit; reproducing the site or large parts of it needs written permission, as the terms explain.
How to credit
Credit line for figures, charts and the API:
Electricity Cost by State, using EIA data (https://electricitycostbystate.com/), July 2026 EIA residential rates, released September 24, 2026.
Link to the page the figure comes from, for example the state's rate page. For the EIA series itself, cite Electric Power Monthly Table 5.6.A or the EIA Open Data API with its release date.
What changed this month
The rates page describes the latest month against the previous month and the same month a year earlier, from the loaded observations only. Each state page has the same analysis for that state. Figures change when the EIA publishes; the changelog records each refresh.
Limits to keep with the numbers
- EIA state rates are averages: total residential revenue divided by kWh sold. Fixed charges are already spread into them, and one household's plan can differ a lot.
- The newest EIA months can be revised; the files hold the values as retrieved on the date in each row.
- Appliance and car costs are estimates for the stated usage, not measurements of a particular home.
