The U.S. Department of Agriculture expects this to be slightly larger than last fall’s record harvest. Depending on the timing and moisture content of the crop, the harvest could have effects on the propane market, as propane is among the fuels used for crop-drying. Propane consumption in corn-producing states typically rises in September and October with the corn harvest, followed by a larger rise related to space-heating needs in January.

The weather influences both the moisture content of the crop and when it reaches maturity. If weather is favorable, farmers may let their corn dry in the field, especially if there is not a price incentive to get it to market right away. Last year, propane demand in the top five corn-producing states increased in October to levels that rivaled the normal peak demand in January, drawing down propane inventories before the heating season began. Propane inventories in the Midwest were drawn down by 4.1 million barrels (130,000 bbl/d) in October, which was the largest October stock draw since 1985.

As a result, Midwest inventories of propane started the heating season at relatively low levels and remained at the bottom of the five-year range through December. , including the closure for maintenance of the Cochin Pipeline that transported propane from Canada to the Upper Midwest and disruptions of rail transportation, prevented Midwest inventories from being replenished before winter began. With prolonged cold weather in January and February, propane inventories dipped well below the five-year range.

Midwest propane inventories are higher going into this harvest season. As of September 26, inventories were above the five-year average and 3.7 million barrels higher than year-ago levels. However, was reversed earlier this year and now moves condensate from the Midwest to Canada. However, at least some of these supplies will be replaced by additional supplies from several existing pipelines that move propane north from Conway, Kansas, to the upper Midwest, as well as by expanded rail and storage capacity in the region.
