Key details include:
- Expected aggregate capital cost of US$1.4 billion.
- Adding 150 000 bpd of Mainline system capacity.
- Adding 100 000 bpd of FSP capacity.
- Capacity is anticipated to be available in 2027.
"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, Enbridge's Executive Vice President and President of Liquids Pipelines. "This project demonstrates the competitive advantage of leveraging existing networks to meet growing customer demand, supporting long-term energy security and affordability across North America".
MLO1 will increase capacity on the Mainline through a combination of upstream optimisations and terminal enhancements. In addition, Enbridge plans to add pump stations and terminal enhancements for FSP to increase capacity and will utilise existing capacity on Seaway Pipeline. The FSP expansion is underpinned by long-term take-or-pay contracts for full-path service from Edmonton, Alberta to Houston, Texas, which support attractive returns for MLO1. As part of the open season process on FSP earlier in 2025, the majority of existing customers elected to extend their existing full-path contracts through the next decade.
