Enbridge halts Sandpiper Project amid regulatory hurdles in 2024 review

The pipeline operator maintained a 10% after-tax return on equity for its Southern Lights assets while streamlining affiliate service costs.

Enbridge (ENB) managed a diverse portfolio of crude oil and liquid petroleum carriers across the U.S. Midwest and Plains during the 2024 report year. The company's network included Enbridge Pipelines (Toledo) Inc. (MI, OH), which operates a common carrier system through Michigan and Ohio, and Enbridge Pipelines (FSP) L.L.C., which extends from Flanagan, Illinois to Cushing, Oklahoma. Other key assets included North Dakota Pipeline Company LLC (MT, ND, MN) and Enbridge Storage (Patoka) LLC (IL), which focuses on crude and liquid petroleum storage in Patoka, Illinois.

Rate structures across the system varied by asset, with Enbridge Pipelines (Southern Lights) LLC employing a cost-of-service tolling methodology. This specific operating company utilized a pre-determined after-tax return on equity (ROE) of 10%.

Operational capacity remained a focal point for the Southern Lights Pipeline, which maintained an operating capacity of approximately 180,000 barrels per day. The pipeline serves as a critical link transporting diluent from Manhattan, Illinois to Edmonton, Alberta. Revenue for this segment was primarily derived from transportation services agreements with five arms-length shippers.

Enbridge faced significant regulatory headwinds regarding its expansion plans. North Dakota Pipeline Company LLC discontinued the Sandpiper Project. Difficulties in obtaining necessary permits, regulatory approval challenges, and shifting demand expectations were the primary drivers for the decision to halt the project.

To manage systemic costs, Enbridge utilized affiliate companies for administrative, management, and workforce services across its subsidiaries. The parent company recorded no profit or margin on these internal charges. Environmental risk management was standardized across the fleet to ensure compliance with state and federal laws.

Integrity management remained a recurring capital and expense priority. Enbridge Pipelines (Southern Lights) LLC adhered to DOT Office of Pipeline Safety requirements, expensing the costs of planning and inspection while capitalizing remedial mitigation work. This disciplined approach to integrity and regulatory compliance defines the company's current operational posture as it navigates the permitting environment for future system additions.
