pipeline tolls

Western Canada’s Trans Mountain Expansion Project, better-known as TMX, has experienced more than its share of setbacks over the past 10 years: environmental protests, legal challenges, financing issues, an ownership change, and even a serious flooding event in 2021. But it seems the 590-Mb/d expansion of the now-300-Mb/d Trans Mountain Pipeline (TMP) system will finally become a reality by early 2024, enabling large-scale exports of Alberta-sourced crude oil to Asian markets. There’s a catch, though. The project’s long delays and other issues resulted in massive cost overruns that are now being reflected in the preliminary tolls for the soon-to-be-combined Trans Mountain system. The proposed toll increase is so large that it will cost a similar amount to ship heavy crude oil to tidewater on Trans Mountain as it would on the competing Enbridge system to the U.S. Gulf Coast for “re-export,” despite the latter being three times the distance. In today’s blog, we discuss the history of the Trans Mountain expansion, its cost overruns and the calculations that went into the proposed tolls — the kicker being that those tolls could end up being even higher.

It took a while, but Enbridge and shippers on its 3.2-MMb/d Mainline system have finally reached an agreement in principle on a new tolling agreement that will lower per-barrel rates on the mammoth crude oil pipeline network between Western Canada and the U.S. Midwest — and also help ensure that Enbridge will earn a healthy rate of return on its largest asset. Assuming the Mainline Tolling Agreement (MTA) is approved by Canadian regulators later this year (and that’s seems to be a safe bet), the new rate structure should also help the Mainline system retain the vast majority of its crude volumes, even as it faces new competition from the Trans Mountain Expansion (TMX) project, which will provide 590 Mb/d of additional pipeline capacity from Edmonton, AB, to the British Columbia (BC) coast starting sometime next year. In today’s RBN blog, we discuss the MTA and what it means for Enbridge, shippers and TMX.
