Customers can contract to purchase their own gas supply (direct purchase option) in both the north and south delivery zones. To be a direct purchase customer, a customer must deliver the natural gas supply they require to Enbridge Gas.
Direct purchase customers can choose to purchase their natural gas supply directly from a supplier or enter into an agreement with a retail energy marketer or broker who will purchase the natural gas supply on their behalf.
There are two service options available to customers, Bundled Transportation (BT) and/or Transportation Service (South T1/T2/T3, North T-service).
