Non-regulated crude oil and liquids contract terminals

Enbridge has established a significant presence in contract storage in recent years, largely driven by increasing production of Western Canadian crude oil and the need for additional transportation infrastructure to access new markets in the U.S.

Currently, Enbridge is operating, or has under construction, contract storage at the following locations:


Hardisty, Alberta is the most important crude oil storage hub in Canada. Enbridge operates approximately 3 million barrels of salt cavern storage at Hardisty Caverns, and 7.5 million barrels of above ground storage at Hardisty Contract Terminal, with both facilities well connected, providing customers with the much-needed optionality they require. Both facilities are currently completely subscribed. Enbridge is continuing to evaluate additional service options and growth opportunities to maximize the value of these facilities for both Enbridge and its customers.


Cushing, Oklahoma is one of the most important crude oil storage hubs in the world and the location of the settlement of the New York Mercantile Exchange West Texas Intermediate (NYMEX WTI) contract. In Q1 2021, Enbridge acquired a facility that includes 34 tanks for a total of approximately 6.6 million barrels of storage at Cushing from Blueknight Energy Partners, L.P. The acquisition, at a price more competitive than building new storage, further strengthens Enbridge’s top-tier position as a leader in the Cushing storage complex. For our customers, this means expanded storage capabilities and connections in Cushing which brings more optionality, flexibility and value.

Houston Oil Terminal

Enbridge is developing a new terminal in the Houston area that will be fully integrated into the Seaway system with access to all existing delivery points and could have future connectivity to both SPOT and Gray Oak. The location supports up to 15 million barrels of tankage and plans to be in service by 2023.


The oil sands have various operational contract tanks throughout the system totaling more than 7 million barrels. Additionally, Enbridge has contract storage locations throughout the North Dakota Classic system, 480,000 barrels of leased storage at Platte Pipeline’s Casper, Wyoming facility, and 400,000 barrels of storage at Patoka, Illinois with a large footprint for future development. Enbridge continues to actively consider and develop future opportunities to add merchant storage across our network.
