After a decade-long odyssey and a cost-per-mile that must make public-sector accountants in Ottawa wince, the Canadian government-owned Trans Mountain Expansion Project (TMX) — which nearly tripled the capacity of the original Trans Mountain Pipeline (TMP) from Alberta to the British Columbia (BC) coast — finally came into service in May 2024. As one of Canada’s most anticipated energy infrastructure projects in many years, the 590-Mb/d TMX pipeline — built alongside the long-standing 300-Mb/d TMP — was widely touted by its advocates as a surefire way to boost exports of Western Canadian crude and reduce the nation’s near-complete reliance on exporting crude oil to — and through — its primary customer, the U.S. In today’s RBN blog, we discuss some of the surprising (and not so surprising) market developments since the expansion project started.
