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.

Utility

Alphabetical. Utilities with no priceable plan are left out.

Your current plan (optional)

The plan name is on your bill. Choose it to see what moving to the cheapest open plan would save.

Electricity used each month

One number, or twelve separated by commas. Which plan wins often changes with the season, so a year of real figures is worth entering.

Sales or utility tax

Applied equally to every plan, so it shifts the totals but not the ranking.

Include fixed monthly charges

Worth turning off and on: a plan with a cheap rate and a high standing charge can win at high usage and lose at low usage.

How this was worked out6 assumptions, 4 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 Arizona, 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
This tariff publishes an export credit. Only consumption is priced here; credits for exported generation are not deducted.Real bill likely lower

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.
