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.

How this was worked out5 assumptions, 3 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 over each day's hours in the typical pattern of homes in Texas, by month and weekday or weekend (NREL/NLR ResStock 2025 Release 1 (AMY2018), timeseries aggregates by state, baseline). A household that uses more in this tariff's peak hours than that pattern pays more than this estimate, and one that uses less pays less.Effect unknown
- No sales or utility tax was applied. Most US jurisdictions add one, so a real bill will be higher.Real bill likely higher
Estimate — your actual bill may differ.

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.
