About PADD 4 (Rocky Mountain) propane price
The Rocky Mountain region, PADD 4, covers Colorado, Idaho, Montana, Utah and Wyoming. Unlike most consuming regions, PADD 4 produces a meaningful share of its own propane: gas processing in Colorado's DJ Basin and Piceance, and in Utah's Uinta Basin, strips propane out of regional gas production, which leaves this region less dependent on long-haul Gulf Coast pipelines than the Midwest or East Coast are. That local supply does not make delivery cheap. Demand is spread thin across mountain counties, high plains and rural towns at elevation, where the heating season runs longer than the calendar alone would suggest and a delivery route can be a long one.
The result is a retail-minus-wholesale spread, in the table above, shaped more by that dispersed, low-density delivery cost than by distance from the Mont Belvieu spot price the way it is in New England. Wyoming, this site's one unsurveyed PADD 4 state, reports no price of its own; the closest read on it is this regional line.
Colorado and Utah, the district's two most populous states, carry most of the demand behind this number; Montana and Idaho run smaller, more rural markets on longer average delivery routes, where a January storm can close a mountain pass and strand a delivery route for days rather than hours.

Common questions
What is the propane price in the Rockies?
Rockies residential propane averaged $2.377/gal in EIA's Oct 26, 2026 survey, with wholesale (rack) propane at $1.229/gal the same week. That was 35.3 cents below the US average of $2.730/gal. The survey runs weekly from October through March, and the chart above carries the full history.
Which Rockies state has the cheapest propane?
In the Oct 26, 2026 survey, Montana had the lowest residential price of the four states EIA surveyed in the Rockies, at $2.179/gal, and Idaho the highest, at $2.686/gal: a spread of 50.7 cents a gallon. The table above lists every one. Delivered prices also vary from house to house with tank ownership, volume and distance from supply.
When is propane most expensive in the Rockies?
In EIA's weekly survey, which runs October through March, Rockies residential propane 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 each of the last five heating seasons. From low to high the price moved an average of 28.5 cents a season, and the seasons table above lists each high and low week. The regional wrinkle is that Rocky Mountain demand is spread thin across mountain counties and high plains, where the heating season runs long and a delivery route can be a long one. Why propane prices rise in winter has the mechanics.
