About South Dakota propane prices
South Dakota heats a larger share of its homes with propane than nearly any other state, and its dealers cover long distances to do it. Grain drying pulls hard through the fall across the eastern counties, and the winter that follows is severe. Supply comes by pipeline into eastern terminals and by rail and truck from the Rockies and the Gulf Coast, which makes a January rail bottleneck a real risk here.
This is a surveyed average rather than a quote. EIA polls a sample of South Dakota propane dealers weekly through the October to March heating season and publishes the state figure Wednesday afternoon; the series then goes quiet until October. EIA also surveys a wholesale price for South Dakota, plotted as the lower line. The distance between the two is the delivered-service stack, and it widens when the rack falls faster than dealers reprice. The Census Bureau's American Community Survey, on five-year estimates, puts propane as the main heating fuel in 15.5% of occupied South Dakota homes, the 3rd highest share in the country. A hard winter is a bigger household event here than the national average suggests.
The regional numbers around this price are Midwest propane prices and Midwest propane stocks, the inventory that has to cover the winter. A price per gallon is not a delivery ticket. The propane usage calculator estimates gallons burned and what a fill costs at the current South Dakota survey price.
Common questions
What is the current propane price in South Dakota?
South Dakota's residential propane price is $1.951/gal as of Oct 26, 2026, the latest reading in EIA's weekly heating-season survey, with the wholesale (rack) price at $1.213/gal on Oct 26, 2026. The chart above carries the full history and the table shows the week-over-week move.
When is propane most expensive in South Dakota?
In EIA's weekly survey, which runs October through March, South Dakota's residential price set its season high in March in three of the last five heating seasons and February in two. The season low came in October in three of the last five heating seasons, November in one and December in one. From low to high the price moved an average of 22.1 cents a season, and the table above lists each season's high and low week. The regional wrinkle is that the Midwest season starts before the thermostat does: propane fires grain dryers across the Corn Belt in October and November, and a wet harvest can pull volume hard weeks ahead of heating demand. Why propane prices rise in winter has the mechanics.
How does the South Dakota propane price compare with the Midwest average?
South Dakota's residential propane price averaged below the Midwest average in each of the last five heating seasons, by between 16.6 cents and 27.8 cents a gallon. In the Oct 26, 2026 survey South Dakota was at $1.951/gal against $2.199/gal for the Midwest average. The seasons table above gives the gap season by season, and Midwest propane prices carries the district's own chart.
What is the difference between the residential and wholesale price on this page?
The residential price is what a South Dakota household pays for a delivered gallon: the dealer's own cost plus trucking, tank service and margin. The wholesale price is that dealer cost at the rack, before any of it. The gap between the two is the delivered-service stack, and how propane is priced walks through each layer of it.
