Enbridge says it is postponing the second phase of its Mainline oil pipeline expansion, which is designed to move Canadian crude to U.S. markets. The company’s announcement comes as it does not approve the next set of improvements to the Mainline system, a key pipeline network used to transport Alberta oil toward the United States Midwest. Enbridge states it is delaying a planned increase of 250 barrels per day related to the expansion. In its release, the company describes the project as having “evolved,” but it does not provide a timetable for when a final decision will be made. Enbridge also does not disclose a specific date for restarting or completing the delayed work, leaving the future timeline open. The postponement affects the planned incremental capacity addition tied to the second phase, while Enbridge continues to operate the existing Mainline network that delivers Canadian crude into the United States. The company’s latest decision therefore shifts the schedule for the expansion’s next stage without changing the ongoing flow through the Mainline system.
