Enbridge’s liquids system is the largest network of crude oil pipelines and terminals in North America. Our integrated system connects producers to key markets and refiners to critical feedstock through a safe and reliable pipeline operation at competitive rates. Vern Yu President, The Mainline System, a complex network Liquids Pipelines, of parallel pipelines moving multiple Enbridge Inc. commodities, is directly connected to the U.S. Midwest and Eastern Canada, which has been our historical core market. Over the years, we've extended our system further south to connect to the Cushing and Patoka markets as well as the important U.S Gulf Coast market and export infrastructure in the region. Due to this complexity and unparalleled connectivity to several premium markets we can optimize throughput and accommodate the changing needs in the market, which provides a unique competitive advantage for our customers. We continue to deliver on low-cost, high impact opportunities to provide additional pipeline egress for our diverse customer base.

Even with the events this past year dealing with multiple waves of COVID, involving demand destruction and supply impacts, Enbridge’s liquids system has been resilient to deliver the much-needed energy to our customers.

Local Canadian Mainline tolling arrangement. rates for service on the U.S. portion of the Mainline System are not affected by the expiry of CTS and will continue to be established by Lakehead’s existing tolling agreements.

Replacing the expired CTS will be a new tolling arrangement that will have a U.S. dollar denominated IJT while providing priority access on a contract basis on the Canadian Mainline. Contracts offered will be available for term lengths of up to 20 years and contain flexible commercial terms for all shippers while providing long- term toll stability and certainty. The new commercial framework will reserve a minimum 10% of the Canadian Mainline capacity as spot service. Enbridge has submitted the application for the new tolling arrangement to the CER and expects a decision in Q4 2021 at which time Enbridge will hold a subsequent Open Season.

The Southern Lights Pipeline transports diluent supply from various sources through the U.S. Midwest to Western Canada’s heavy oil production regions.

Southern Lights Originating from Manhattan, Illinois, Southern Lights sources its diluent from the U.S. Gulf Coast, mid-continent and Midwest refineries via interconnections to existing crude and refined products pipelines and delivers it to Western Canada’s crude oil hubs. Southern Lights receives product from three connecting carriers at the Manhattan Terminal in Illinois—BP, Enterprise and Explorer pipelines.

At the terminus of the system in Edmonton, Alberta, Southern Lights has direct delivery connections to the CRW pool, Keyera, Gibson, Pembina, Plains and Access pipelines. Currently, there is also a direct delivery connection to the Enbridge Mainline at Hardisty, Alberta, and to Plains at Kerrobert, Saskatchewan.

The annual average capacity of Southern Lights is 180,000 bpd, of which 162,000 bpd is secured by long-term contracts. As referenced in the Oil Sands Infrastructure Development section, the Norlite Project is a key component of Enbridge’s overall diluent strategy, extending diluent delivery into the Oil Sands region.
