Enbridge has approved a $1.4-billion expansion of its Mainline and Flanagan South pipelines to increase takeaway capacity for Canadian heavy crude bound for US Midwest and Gulf Coast refineries. The Mainline Optimization Phase 1 project will add 150,000 bpd to the Mainline and 100,000 bpd to Flanagan South, with new capacity expected in 2027. Enbridge says the expansion will support growing oil sands production and improve access to key refining markets. Backed by long-term take-or-pay contracts from Edmonton to Houston, the project involves system optimizations, terminal upgrades, new pump stations, and expanded terminal capacity.
