Why Louisiana Propane Prices Sit Where They Do
Southern propane prices are typically the lowest in the country. The region is closest to Gulf Coast production, has shorter supply chains, milder winters that limit peak demand, and a high share of households with natural gas, leaving propane primarily for rural and supplemental use.
Louisiana specifically sits at $2.19/gal, -10% versus the South regional average. Local supply chain length, household propane-heating share, regional storage capacity, and population density all combine to set the retail rate.

Louisiana Propane Fill-Up Cost by Tank Size
Propane tanks are filled to 80% capacity (the "80% rule") to allow for thermal expansion. Costs below use Louisiana's $2.19/gal residential rate and the usable gallon count for each tank size, compared to the national-average rate of $2.78/gal.
| Tank size | Usable gallons (80%) | Louisiana fill cost | National avg cost | Louisiana discount |
|---|---|---|---|---|
| 100 gal (portable) | 80 | $175.20 | $222.40 | -$47.20 |
| 250 gal (small home) | 200 | $438.00 | $556.00 | -$118.00 |
| 500 gal (standard residential) | 400 | $876.00 | $1112.00 | -$236.00 |
| 1,000 gal (large home / cold-climate) | 800 | $1752.00 | $2224.00 | -$472.00 |
A typical Louisiana household heating a 2,000 sqft home burns 800 to 1,200 gallons per year, which translates to two or three full fills of a 500-gallon tank. Annual propane spend ranges from $1752 (low usage) to $2628 (high usage) at the current statewide average rate.
How to Find a Licensed Propane Supplier in Louisiana
Buying propane from an unlicensed dealer is both a safety risk and a consumer-protection risk: licensed dealers must comply with NFPA 58 storage and delivery standards, carry insurance, and follow state-specific consumer rules on tank ownership and contract disclosure. Three reliable starting points:
- National Propane Gas Association (NPGA) member directory at npga.org — the national trade association lists licensed propane retailers across all 50 states.
- Louisiana state propane gas association — most states maintain their own licensed-dealer directory under a name like "Louisiana Propane Gas Association" or via the state Department of Agriculture / Weights and Measures office. Search for the directory and use the official state-licensed list.
- Local-licensing public records — your state Department of Agriculture or Department of Consumer Protection typically publishes a registered propane dealer list. If a company quoting you is not on the state list, do not sign.
Always get a written quote that itemises per-gallon price, delivery fee, tank rental (if applicable), minimum-delivery surcharge, and any monthly tank fee. Compare two or three quotes before committing. Per-gallon spreads of 30 to 50 cents within the same county are common.
