Electricity rates in South Dakota

Average rate: 15.36¢
A year ago: 14.22¢
vs US average: -16%
Rank: 33 / 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 South Dakota draws exactly what it draws in Nevada, it just costs 1.2× as much to run.

What a typical bill looks like in South Dakota

South Dakota sits in the West North Central census division, where the EIA’s Residential Energy Consumption Survey puts average household electricity at 10,705 kilowatt-hours a year — 1% above the national figure of 10,566 kWh. At 15.36¢ that is $1,644 a year, or $137 a month before fixed charges and taxes.

$137 a month · 10,705 kWh, the West North Central average

Using the national average instead would put this at $1,623 — 1% lower. Region is the second-biggest variable after the rate itself.

Where the electricity goes in the West North Central

The West North Central is a heating region: electric heating runs to 3,472 kWh against 1,728 kWh for cooling. 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, West North Central division, priced at South Dakota’s 15.36¢/kWh. The parts do not sum to the total because each is conditioned on different households.

End use	West North Central	National	Difference	Cost in South Dakota
Space heating	3,472 kWh	2,484 kWh	+40%	$533
Water heating	2,870 kWh	2,706 kWh	+6%	$441

What South Dakota 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 South Dakota a household pays 15.36¢ while industry pays 9.44¢ — 1.6× 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, South Dakota. 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	15.36¢	14.22¢	+8.0%
Commercial	11.35¢	11.28¢	+0.6%
Industrial	9.44¢	8.77¢	+7.6%
All sectors	12.25¢	11.67¢	+5.0%

One month is weather. The year is your bill.

The June 2026 figure above is a single month. Across 2026 so far, South Dakota residential customers have averaged 14.33¢ — 7.2% 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 South Dakota will not look like a July one, even at identical usage.

Against 15.36¢ in June 2026 alone · 12.91¢ 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 South Dakota

Every appliance on this site, priced at South Dakota’s 15.36¢. 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 South Dakota’s average residential rate of 15.36¢/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 South Dakota?

15.36 cents per kilowatt-hour for residential customers in June 2026, according to the EIA’s Electric Power Monthly. That is 16% below the national average of 18.34¢, and ranks 33 out of 51 for price.

What is a typical electricity bill in South Dakota?

A household using the US average of 10,705 kWh a year would pay about $1,644 a year, or $137 a month, at South Dakota’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 South Dakota gone up?

South Dakota residential rates are up 8% against the same month a year earlier, from 14.22¢ to 15.36¢. 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.
