May 12, 2020

The CER has issued an update on adjudicative processes during the COVID-19 pandemic


What’s New

Project Information

On December 19, 2019, Enbridge Pipelines Inc. filed an application for a new service and tolling framework for its Canadian Mainline pipeline system. If approved, the new framework will allow shippers to sign long-term contracts for priority access to 90% of the capacity on the pipeline system. Currently, Enbridge allocates capacity on the Mainline on an uncommitted basis, using a monthly nomination system. Enbridge intends to reserve 10% of the available capacity of the Mainline for shipments of spot or uncommitted volumes. Any contracted capacity that is not used for contract shipments would be available for spot shipments. The applied-for service offering, which also includes requests for various other related approvals, would replace the current service and tolling settlement, which is due to expire on 30 June 2021. In its application, Enbridge indicated that the new contracts would go into effect only once the Line 3 Replacement Program and its additional 370,000 barrels per day of capacity comes into service.
