Rate Plan Comparator
Utilities publish several plans and rarely tell you which one suits your usage. This prices every plan they offer against the same consumption, and ranks the ones a household can actually move onto today, so the ranking reflects your household rather than a headline rate.
Not every utility. 1210 tariffs from 217 utilities, retrieved up to October 8, 2026. A utility missing here is one that has not been indexed yet.
No plan at Intermountain Rural Elec Assn is both open to every household and a current price.
Nothing to rank
No plan Intermountain Rural Elec Assn publishes is both open to every household and a current price, so no plan is called cheapest. The plans it does publish are priced below, each with the reason it is not ranked.
Plans open to every household, cheapest first
None. Every plan below is either restricted or not a current price.
Restricted plans — priced, not ranked (1)
Means-tested, closed to new customers, needing particular equipment, or only part of a bill. Each is priced so a household that qualifies can compare it.

|---|---|---|---|
| Residential Service (A)demand charge · in effect since March 2024 · billed on peak kW, which monthly use cannot price | $1,440.68 | 13.3¢ | Low confidence |
Older schedules — priced, not ranked (7)
Open to any household on paper, but not a current price: in effect more than 3 years before the rates were checked, undated, or from a utility that no longer sells them.

How this was worked out8 assumptions, 5 that could move the total
- Priced against the 2026 calendar. Weekday and weekend day counts differ between years, which moves the total on a time-of-use tariff.No effect on the total
- Weekend rates are applied on Saturday and Sunday. URDB publishes no holiday calendar, so utilities that bill public holidays at weekend rates are not reflected.Effect unknown
- Hours are local clock hours with no daylight-saving shift, matching how time-of-use periods are written in the tariff.No effect on the total
- Monthly totals were spread evenly across every hour. This tariff prices every hour the same way, so the result is unaffected.No effect on the total
- This tariff bills peak demand, but no hourly readings were supplied. The peak was derived from an even spread of monthly usage and will be far below a real household peak.Real bill likely higher
- No sales or utility tax was applied. Most US jurisdictions add one, so a real bill will be higher.Real bill likely higher
- Unmodelled tariff feature (malformed_schedule): demandweekdayschedule references period 1 but only 1 period(s) are defined.Effect unknown
- Unmodelled tariff feature (malformed_schedule): demandweekendschedule references period 1 but only 1 period(s) are defined.Effect unknown
Estimate — your actual bill may differ.
Tariff data: NREL/OpenEI Utility Rate Database (CC0 1.0), retrieved October 8, 2026.
Indexed so far: 1210 tariffs from 217 utilities. Not every utility. Utilities are reached two ways: by probing population-centre coordinates in 18 states, and by fetching, by EIA number, the utilities that serve most of each state's homes according to EIA-861. A smaller utility outside both — many rural cooperatives and municipal utilities — will not appear here yet.
