About PADD 1C (Lower Atlantic) propane stocks
South of the Central Atlantic, the Lower Atlantic covers Florida, Georgia, the Carolinas, Virginia and West Virginia, the southernmost of the three East Coast storage areas this site tracks. Pipeline capacity built to run from the Gulf Coast into the Southeast reaches this region, supplemented by coastal import terminals along the Florida and Georgia shoreline, giving the Lower Atlantic a more direct tie to Gulf Coast supply than New England has. Winters here are milder than the rest of the East Coast, so the seasonal draw is typically shallower, though stocks still build through the summer and draw down through the colder months on the same calendar as the rest of the country. Its five-year band measures this region's own cushion against its own history, not against the colder sub-regions to its north.
Judging this area against a national build or draw usually understates it, because the winter is milder and the seasonal swing is shallower. The comparison that works is the region against its own history. What the series counts is primary storage, propane and propylene together, across terminals, pipelines and gas plants, in thousand barrels, out of the Weekly Petroleum Status Report every Wednesday for the week ended the previous Friday. Southeastern demand also has a crop side that the heating calendar misses: poultry houses run propane brooders and peanut and grain drying pulls volume in the fall, both of them ahead of any real cold.
Common questions
Is PADD 1C (Lower Atlantic) propane inventory high or low right now?
PADD 1C (Lower Atlantic) propane stocks stood at 1.7 million barrels as of Aug 28, 2026, 1% below the 5-year median of 1.8 million barrels for this point in the year. A level under the band means a thinner cushion than usual going into the draw season.
What is the 5-year average for PADD 1C (Lower Atlantic) propane stocks?
1.8 million barrels for this week of the year, measured as the 5-year median rather than a flat annual average, because propane inventories swing hard by season and a single yearly number would compare a March level against an August one. Propane inventories and the 5-year average explains how to read the band.
How do propane stock levels affect prices?
Inventory is the cushion between winter demand and the physical supply that can reach a market in time. When stocks run under their seasonal band going into October, buyers competing for a thinner cushion bid up the Mont Belvieu spot price, and delivered prices follow with a lag as dealers replace barrels at the higher cost. A comfortable build has the opposite effect: it absorbs a cold snap without a price response.
When are PADD 1C (Lower Atlantic) propane inventories typically lowest?
The Lower Atlantic bottoms out in February or March, but the seasonal swing is shallower than further north because the winter is milder. Fall poultry-brooder and crop-drying demand starts the draw earlier than the heating calendar would suggest.
