How this works
Electricity pricing is public information that almost nobody reads, because it lives in tariff PDFs hundreds of pages long. This site reads them so you don’t have to.
Where the rates come from
Every price on this site comes from the NREL Utility Rate Database, a public-domain dataset the National Renewable Energy Laboratory maintains from utilities’ own filings with state regulators. We add nothing to it and we do not negotiate with utilities.

Tariffs change on regulatory schedules — months, not minutes — so this is a build-time snapshot, not a live feed. The dates above are shown on every page for the same reason: a number whose age you don’t know is indistinguishable from a wrong one.
What we throw away
The raw database is larger than what you see here. Most of it we deliberately drop:
- Expired plansMore than half the residential entries have an end date that has already passed. They still come back in the database’s default responses.
- Plans closed to new customersSome tariffs read like a great deal and then say, in the fine print, that applications stopped being accepted in 2014.
- Partial tariffsIn states where you can pick your own supplier, some entries price only the delivery half of your bill. Quoting those as a total would be off by a factor of three.
- Anything older than 2024A rate filed years ago is not what you would pay today.
What survives that filter covers about two thirds of US ZIP codes. For the rest we say we don’t know, which is less satisfying and more accurate.
Limits you should know about
- Estimates, not quotes. Your real hour-by-hour usage is not exactly the one we model. What holds up is the gap between plans, since both are priced off the same assumptions.
- Supply charges move monthly. In deregulated states the energy half of your bill is reset every month and cannot be known in advance.
- ZIP codes are mail routes, not service territories. Where several utilities overlap, we show all of them and let you pick the one on your bill.
- Rate zones are on your bill, not in the data. Utilities like PG&E and ConEd price differently by climate or load zone, and no public dataset maps addresses to them.
- Demand charges are not priced. A small number of plans bill on your single highest hour. We flag them rather than guess.
- Holidays are not modeled. Some utilities bill holidays at weekend rates, which would make our summer peaks slightly high.
Who runs this
An independent project. We are not a utility, a broker, or an energy supplier, and we do not sell your information or earn a commission when you switch plans. The site is supported by advertising, which is why we can afford to cover the regulated states where nobody earns a switching fee.
