Propane imports

The leaves have already fallen off New England’s trees, the first snow has come and gone, and the six-state region is preparing for another long, cold winter — this time with no Tom Brady and little hope that their beloved Patriots will make it to the playoffs. There is at least some good news, though: record volumes of propane have been railed or shipped into New England and put in storage, which should help to ensure that the many homes and businesses that depend on the fuel for space heating will stay warm. Today, we discuss propane supply and demand in the northeastern corner of the U.S., including a look at SEA-3 Newington — New England’s largest propane storage and distribution center, which rails in the fuel from the Marcellus/Utica and Canada and imports and exports propane by ship.

During the spring, summer and fall of 2016, U.S. propane inventories grew much more slowly than they did in the same period in 2014 and 2015, in part due to fast-rising exports. The situation isn’t dire––propane stock levels are relatively high as the winter of 2016-17 really kicks in, largely because last winter was a mild one that left inventories in good shape when the 2016 stock-building period started. But even-higher exports and the possibility of a “real” winter this time around raise the specter of an especially big drop in stored volumes over the next three months. Today we assess what the combination of higher exports and even an average winter could mean for propane inventories.

U.S. propane inventories rose by an impressive 55 million barrels (MMbbl) during the spring/summer/fall of 2014, and the mild winter of 2014-15 left propane stocks at well-above-normal levels the following spring. Another impactful inventory build—53 MMbbl—occurred during 2015’s March-to-November stock-building season, leaving propane stocks at a record 104 MMbbl as the freakishly mild winter of 2015-16 started. But propane inventories grew much more slowly through the spring/summer/fall of 2016, due in part to rising exports, and—while stocks are high as this winter begins—even-higher exports and the possibility of real winter weather raise the specter of an especially big drop in stored volumes. In today’s blog we begin a series on the significance of propane inventory levels with a look at why propane stocks rose so much in the 2014 and 2015 stock-building seasons.
