Electricity rates by utility

A state average blends every supplier in the state, and this site has said so on four pages while publishing exactly fifty-one numbers. Here is the layer underneath: 1,192 utilities across 38,564 zip codes, each with what it actually charged.

The spread inside one state

This site’s most repeated finding is that the rate matters more than the appliance: electricity costs 4× more in the dearest state than the cheapest. What a state average cannot show is that the same gap exists within a state. In California, Sacramento Municipal Util Dist averaged 17.87¢ while San Diego Gas & Electric Co averaged 43.63¢ — 2.4×, for identical electricity, in the same year.

The twelve widest, among utilities serving 100+ zip codes. Residential averages, EIA-861 2024. Small municipals and co-ops are excluded from this comparison because a supplier serving one town is not an alternative to one serving a million homes.

The cheap end of that list is almost always public power — a municipal utility or a co-op — and the dear end is almost always investor-owned. That is a real pattern and not a recommendation: you cannot choose which wires reach your house, and in a deregulated state what you can choose is the generation half of the bill, not the delivery half.

Every utility with a page

Grouped by the state each one serves most. 109 utilities, each serving 100 or more zip codes; the other 1,083 answer the lookup above but do not have a page of their own.

What this cannot tell you

It is an average across every residential customer a utility has, on every plan — time-of-use, all-electric, low-income and standard alike. It is one year old at best. And it is one utility on its own, while a state average is weighted by how much each utility sells, so the two are not the same kind of number and this site never averages these rows into a state figure.

What it is good for is placing yourself: whether you are on the cheap or the dear side of your own state, and by how much. For the number that is actually yours, divide your bill by its kilowatt-hours — which includes the fixed charge and is usually a little above any published average.

Questions

Why does my zip code show more than one utility?
Zip codes are postal routes and service territories are not drawn to match them, so a zip can straddle a boundary. Where that happens both suppliers are listed and your bill says which one is yours.
Why is my zip code missing?
The dataset covers 38,564 zip codes, which is most but not all of them: a zip with no residential customers, or one served by a utility that did not report a residential rate that year, has nothing to show. The state average is the fallback, and your own bill beats both.
Is this what I will pay?
No, and two things separate it from your bill. It is an annual average across every residential customer that utility has, on every rate plan; and it is 2024, while the state averages elsewhere on this site are June 2026. Nationally the residential average rose from 16.48¢ to 18.34¢ across that gap. Use it to see where you sit, then divide your own bill by its kilowatt-hours for the number that is yours.
