Every US residential electricity tariff, priced.
911 currently maintained residential tariffs from 183 utilities — decoded from the raw filings, with tier ladders, time-of-use schedules and fixed charges applied properly. Drawn from a catalog of 6,357 on file, of which we publish only what is recent enough to price against.
Why this is harder than it looks
Utility tariffs are public, but they are published as filings, not as prices. A single residential rate can carry a tiered ladder whose thresholds reset daily rather than monthly, a time-of-use schedule that differs by month and by weekday, a fixed charge billed per day rather than per month, and a rider that is added to the headline rate rather than included in it.
Get any one of those wrong and the answer is not slightly off, it is wrong by a multiple. We publish exactly how we handle each of them, and we refuse to estimate the 344 rates that cannot be priced from consumption alone rather than guessing at them.
The bigger trap is age. A tariff in the national database with no end date is not necessarily in force — it means nobody recorded an end. Filings more than a decade old sit about 17% below what their utility now actually charges, so ranking without regard to the filing date puts stale data on top of every "cheapest" table. We rank only tariffs filed since 2020 and label every figure with its year. See which utilities are maintained →
