Propane supply

It’s the 10-year anniversary of a polar vortex winter that’s seared into the memories of every propaner who lived through it. Shortages. High prices. Government inquiries. Sure, there were difficulties during that winter in the markets for natural gas and fuel oil too, but it was particularly bad for propane. It seemed like a perfect storm hit the propane market right where it hurt the most — in the heart of propane country: the Upper Midwest and the Northeast. A lot has changed since then, but it’s important to look back at what went wrong, what’s been done to make a repeat of that chaotic winter far less likely, and what those events still mean for the propane market today. 

Amid all the turmoil and negative news in energy markets this year, U.S. propane has been the exception, turning in a stellar performance. Even with exports up almost 10% in November from the same period last year, averaging 1.3 MMb/d for the month, inventories remain in good shape at 92.6 MMbbl, or about 5% above stocks in November 2019. Part of the reason has been strong production numbers, which are down only 5% since January, and up a whopping 14% since May. Weather has been another contributor to robust stock levels, with November 2020 coming in as one of the warmest on record. But winter is just arriving. And with export volumes now greater than total U.S. winter consumption, market dynamics have shifted. It now takes more inventory in the ground throughout the winter to support the combination of U.S. demand and exports. But how much more inventory is enough? And how should we factor in the potential for further increases in exports? At the same time, the market is still facing the possibility of another round of declining production due to COVID-related drilling cutbacks. This blog series is about making sense of what’s going on in the propane market today, and what may be coming up in the months ahead. 

Canada’s propane market has quickly morphed from one characterized by abundant supply to one facing a tightening supply/demand balance, with direct exports to Asia playing an increasingly important role. This tension became evident in May 2019, when the start-up of the Ridley Island Propane Export Terminal (RIPET) in British Columbia, Canada’s first direct export connection for propane to Asian markets, effectively eliminated the usual seasonal surplus for propane in Western Canada. With rail exports of propane to the U.S. often reliant on that excess for restocking in the summer months and as a reliable fallback supply in the cold winter months, the prospect of fewer or no periods of excess supply may be signalling trouble for some U.S. regions that have come to rely on those volumes. What’s more, within a few months, another propane export terminal in BC will be starting up, further reducing what’s left for the U.S. market. In today’s blog, we conclude our series examining the Western Canadian propane market by considering the impacts of Canada-to-Asia propane sales on U.S. propane consumers and propane prices.

During the last two weeks of April, a barrel of propane in Mont Belvieu was more expensive than a barrel of WTI crude oil in Cushing. That’s never happened before. You might think that such an aberration could be blamed on the wacky April-May 2020 COVID crude market, but that is only part of the story. Propane production is falling and pre-COVID projections of continued supply growth are out the window. But new gas processing plants, pipelines, fractionation facilities, dock capacity and downstream demand have come online in recent years, in anticipation of those ill-fated additional supplies. Already we are seeing flows, price relationships and differentials convulsing in response to the new reality, and projections of future supply/demand imbalances suggest a previously unthinkable possibility: a market that can’t get enough propane supply, especially if the winter of 2020-21 is a cold one. In today’s blog, we will explore the evidence of these market developments that is already visible and look to what may be ahead for propane supply and demand.

Until just a few years ago, the rise and fall of U.S. propane inventories each year was driven in large part by winter weather: the colder the temperatures in the major propane-consuming areas, the bigger the draw on stocks. Things have gotten much more complicated lately, though, thanks to a combination of rapid NGL production growth, a generally booming propane export market, and the vagaries of petchem margins. Now, to get a handle on propane stocks, you not only need to be able to forecast the weather, you also need to monitor international propane arbs and steam cracker economics — oh, and crude prices too, because they have a significant effect on NGL output and propane supply. Today, we discuss the many factors that impact propane inventories and prices in this sometimes chaotic market.

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.
