Enbridge Adding Canadian Egress to Key U.S. Refining Markets, Enhancing North American Energy Security

Executive Summary

• Enbridge announced a Final Investment Decision (FID) for Mainline Optimization Phase 1 (MLO1), adding significant crude oil egress capacity from Canada to U.S. Midwest and Gulf Coast markets.
• The project carries an estimated aggregate capital cost of US$1.4 billion and will increase Mainline system capacity by 150 kbpd and Flanagan South Pipeline (FSP) capacity by 100 kbpd, with service expected to commence in 2027.
• Long‑term take‑or‑pay contracts underpin the expansion, supporting attractive returns and reinforcing North American energy security.

Key Details

• Project Scope: Mainline Optimization Phase 1 (MLO1) – upgrades to Enbridge’s Mainline network and Flanagan South Pipeline (FSP).
• Capital Cost: Approximately US$1.4 billion total investment.
• Capacity Additions:
• 150,000 barrels per day (kbpd) of additional capacity on the Mainline system.
• 100,000 kbpd of added capacity on the Flanagan South Pipeline.
• Timeline: Capacity is anticipated to be in service by 2027.
• Strategic Rationale: Provides incremental egress for Canadian heavy oil to key U.S. refining hubs (PADD II – Midwest; PADD III – Gulf Coast), supporting Canadian production and enhancing North American energy security and affordability.
• Contractual Backing: Expansion is underpinned by long‑term take‑or‑pay contracts covering full‑path service from Edmonton, Alberta to Houston, Texas, with most existing customers extending contracts through the next decade.
• Implementation Elements:
• Upstream optimizations and terminal enhancements on Mainline.
• Additional pump stations and terminal upgrades for FSD expansion.
• Utilization of existing capacity on the jointly‑owned Seaway Pipeline (50/50 Enbridge & Enterprise Products Partners).
• Executive Quote: “MLO1 is expected to add capital‑efficient and timely egress capacity from Canada, supporting Canadian production and increasing connectivity to the best refining markets in North America,” said Colin Gruending, Executive Vice President & President of Liquids Pipelines.
