Enbridge Gas has a robust portfolio of energy services and solutions to help businesses meet their energy needs, manage costs in the face of rising fuel prices, and stay efficient.

Large-volume distribution contract rate options

Customers can contract for distribution services, provided they meet all the eligibility requirements of the Union South delivery zone contract rate class. The volume of use will determine your qualifying rate class. Customers with contract rate services have specific parameters for daily, hourly and annual (if applicable) natural gas use, as well as for the minimum guaranteed pressure of the natural gas delivered during the term of the contract.

Customers can choose to purchase their natural gas supply from Enbridge Gas (sales service) or purchase their own natural gas supply from a retail energy marketer or broker (direct purchase). The option you choose (listed below) will determine the type of contract(s) you'll sign with Enbridge Gas.
