Electricity rates in Idaho

Average rate: 14.37¢
A year ago: 12.07¢
vs US average: -22%
Rank: 42 / 51

Every figure below is that rate applied to the same appliance models used across this site. The rate is the only thing that changes between states — a refrigerator in Idaho draws exactly what it draws in Nevada, it just costs 1.1× as much to run.

What a typical bill looks like in Idaho

Idaho sits in the Mountain census division, where the EIA’s Residential Energy Consumption Survey puts average household electricity at 10,500 kilowatt-hours a year — 1% below the national figure of 10,566 kWh. At 14.37¢ that is $1,509 a year, or $126 a month before fixed charges and taxes.

$1,509a year

$126 a month · 10,500 kWh, the Mountain average

Using the national average instead would put this at $1,518 — 1% higher. Region is the second-biggest variable after the rate itself.

Where the electricity goes in the Mountain

The Mountain is a cooling region: air conditioning runs to 2,918 kWh against 1,795 kWh for electric heating. These are conditional averages — each is the mean among households in the division that actually use electricity for that purpose, so they describe a home that has the thing, not a blend across homes that do not.

EIA RECS 2020, table CE4.6, Mountain division, priced at Idaho’s 14.37¢/kWh. The parts do not sum to the total because each is conditioned on different households.

End use	Mountain	National	Difference	Cost in Idaho
Air conditioning	2,918 kWh	2,318 kWh	+26%	$419
Water heating	2,550 kWh	2,706 kWh	-6%	$366

What Idaho households pay against everyone else

The same grid sells to households, businesses and factories at different prices, because delivery costs are spread over very different volumes. In Idaho a household pays 14.37¢ while industry pays 10.23¢ — 1.4× as much per kilowatt-hour. That ratio is not a scandal; it is the cost of running low-voltage distribution to individual houses rather than a single high-voltage feed to one plant. But it is the reason a household’s cost-saving arithmetic never looks like a business’s.

Average price by end-use sector, Idaho. EIA Electric Power Monthly table 5.6.A. A dash means the EIA published no figure for that sector.

Sector	June 2026	June 2025	Change
Residential — your bill	14.37¢	12.07¢	+19.1%
Commercial	9.92¢	9¢	+10.2%
Industrial	10.23¢	9.94¢	+2.9%
All sectors	11.33¢	10.35¢	+9.5%

One month is weather. The year is your bill.

The June 2026 figure above is a single month. Across 2026 so far, Idaho residential customers have averaged 12.8¢ — 12.3% below that single month.

That is a wide gap the other way: this month is dearer than the year has been, which usually means summer peaking. A January bill in Idaho will not look like a July one, even at identical usage.

Against 14.37¢ in June 2026 alone · 11.44¢ over the same period last year

An annual bill reflects the year-to-date figure far more closely than any single month. Use it in the calculators if you are planning a year ahead.

What each appliance costs in Idaho

Every appliance on this site, priced at Idaho’s 14.37¢. Each figure uses the appliance’s real duty cycle — the share of its running time it actually draws power — so a refrigerator here is 420 kWh a year rather than the 1,314 kWh that nameplate arithmetic produces.

All 120 appliances at Idaho’s average residential rate of 14.37¢/kWh, on this site’s standard usage assumptions. “Real average” is the draw averaged over the hours the appliance is in service.

Questions

What is the average electricity rate in Idaho?

14.37 cents per kilowatt-hour for residential customers in June 2026, according to the EIA’s Electric Power Monthly. That is 22% below the national average of 18.34¢, and ranks 42 out of 51 for price.

What is a typical electricity bill in Idaho?

A household using the US average of 10,500 kWh a year would pay about $1,509 a year, or $126 a month, at Idaho’s average rate. Actual usage varies far more than rates do — an all-electric home with electric heat can use two to three times that.

Have electricity rates in Idaho gone up?

Idaho residential rates are up 19.1% against the same month a year earlier, from 12.07¢ to 14.37¢. The national average moved up 5.0% over the same period.

Why is my rate different from this number?

This is a statewide average across every residential customer and every utility, including fixed monthly charges spread over the kilowatt-hours sold. Your own effective rate depends on your utility, your tariff and whether you are on time-of-use pricing. Divide the total amount on your bill by the kilowatt-hours it lists to get the figure that actually applies to you — that is the number to type into the calculators here.
