About PADD 3 (Gulf Coast) propane stocks
PADD 3, the Gulf Coast, is where most of the country's propane originates rather than where most of it is used. Refineries and gas processing plants here produce the bulk of US supply, and the salt caverns around Mont Belvieu hold the country's largest concentration of underground storage, the reserve that pipelines draw down to supply the Midwest and the East Coast through the winter. The Gulf Coast is also the export hub: cargoes loaded here for Asian and Latin American buyers are the biggest structural claim on the summer build, competing with the rest of the country for the same barrels. Stocks build here from spring through summer and draw down through the heating season like everywhere else, but because this region supplies the others, its five-year band reads on export demand as much as on winter weather.
