Gas processing plants in the DJ Basin northeast of Denver and in the Piceance on the Western Slope strip it out of the raw gas stream, which leaves the state less dependent on long-haul pipelines from the Gulf Coast than most of the Midwest is. Demand concentrates in the mountain counties and on the eastern plains, where houses sit past the end of the gas mains and the heating season runs long at altitude. The price above comes from EIA's State Heating Oil and Propane Program, which surveys a sample of retail dealers in Colorado once a week and publishes the state average on Wednesday afternoon. It runs October through March only, so nothing new prints between April and September. Two lines run on the chart because EIA surveys Colorado dealers on both sides of the sale: what they pay at the rack and what they charge a residential customer. The lower line moves first, and the retail line follows it with a lag measured in weeks. The Census Bureau's American Community Survey, on five-year estimates, puts propane as the main heating fuel in 4.9% of occupied Colorado homes, below the national middle. For context beyond one state, Colorado sits in the Rocky Mountain district: [regional prices](/region/padd4) and [Rockies and West Coast propane stocks](/stocks/padd4-5).

EIA surveys residential propane prices only from October through March, so there is no current residential figure for Colorado right now. The wholesale (rack) price dealers pay in Colorado is $0.973/gal a gallon as of Mar 30, 2026, and the last surveyed residential price was $2.302/gal on Mar 30, 2026. The weekly survey restarts in October. ### When is propane most expensive in Colorado? Residential propane runs highest in the middle of the heating season, ordinarily January and February, and cheapest through the summer while [Rocky Mountain stocks](/stocks/padd4-5) are building and nothing is drawing on them. 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](/guides/why-propane-prices-rise-in-winter) has the mechanics. ### What is the difference between the residential and wholesale price on this page? The residential price is what a Colorado 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](/guides/how-propane-is-priced) walks through each layer of it. ## About this data - Source: EIA State Heating Oil and Propane Program survey - Series: Residential retail propane price - Basis: Residential, retail - Geography: Colorado propane prices - Unit: $/gal - Calculation period: Weekly survey, Oct-Mar heating season - Last observation: Mar 30, 2026 - Update frequency: Weekly, Oct-Mar --- Cite: Residential propane in Colorado propane prices averaged $2.302/gal as of Mar 30, 2026 (EIA).
