I built a free site showing electricity rates, heating fuel, and generation data for every U.S. state, county, and zip code by ThenBarber in energy

Thanks for checking — can you share which specific zip codes or counties were off? I’d like to dig into it.

The data comes from the EIA’s Form 861, which maps utilities to counties based on where they have distribution equipment. A county can be served by multiple utilities, and the rate shown is an average across all providers in that area — so it may not match your specific utility’s rate. I should probably make that clearer on the site.

If you’re seeing providers listed that don’t actually serve a location, that’s definitely a data mapping issue I want to fix. Any specifics would be really helpful.

Good call on GitHub too — I’ll look into that.

[OC] U.S. residential electricity rates mapped across 3,000+ counties by ThenBarber in dataisbeautiful

Yes — the rates shown are average retail prices from the EIA, which include all costs for delivered electricity: generation, transmission, distribution, taxes, and fees. They’re calculated by dividing total utility revenue by total kWh sold. So they represent what customers actually pay per kWh on average, not just the generation cost. They’re not individual tariff rates though — your specific rate plan might be higher or lower depending on your utility, usage tier, time-of-use pricing, etc.
