Enbridge Gas files an Application for 2023 Demand Side Management Deferral and Variance Account Clearing

On Oct. 14, 2025, Enbridge Gas applied to the Ontario Energy Board (OEB) to dispose of its 2023 Demand Side Management (DSM) deferral and variance account balances (EB-2025-0189). The DSM program is our energy conservation program that is available to customers. The DSM program operates under a unified Enbridge Gas framework, aligning both the Enbridge Gas Distribution (EGD) and Union rate zones.

The proposed 2023 DSM deferral and variance account adjustment includes the actual cost of delivering the DSM programs (versus the budgeted costs built into 2023 rates), revenue recovery attributable to consumption reduction due to DSM conservation measures (Lost Revenue Adjustment Mechanism), as well as incentives Enbridge Gas earns when meeting OEB-approved DSM targets. The proposed adjustment does not include any gas cost-related deferrals that are managed under the QRAM process or other non-commodity deferral balances.

Once the OEB completes its review and provides their final decision on this application, clearance of these balances would result in a one-time rate adjustment being applied to bills for all customers who received in-franchise delivery services. Enbridge Gas has proposed to uniformly dispose of the balances with a one-time billing adjustment effective as early as April 1, 2026. This date is dependent on the timing of the OEB’s decision, and we will provide further information when a decision is received from the Board.

How to Estimate the 2023 Deferral Adjustment

You can estimate your customers’ 2023 deferral adjustment by multiplying the proposed rate adjustment that applies to their service (shown below) by the actual volume of natural gas they consumed in 2023.

Reminder for Customers with an Interruptible Distribution Service

Enbridge Gas is reminding customers that when their company receives a Notice of Interruption, their company has a contractual obligation to comply with the notice.

When Enbridge Gas issues a Notice of Interruption, interruptible customers must reduce their natural gas usage to the contracted firm levels as per the applicable schedule of their large volume distribution contract, in accordance with the instructions in the Notice of Interruption.

An interruptible customer’s company must have the ability to reduce its natural gas consumption to contracted firm levels. If their company has not contracted for any firm service, the company must completely cease consuming natural gas during the interruption period. To avoid potential disruption to a company’s operations and/or non-compliance charges, it is the company’s obligation to ensure their back-up systems are tested and ready to use, and that adequate alternate fuel supply is on hand in the event of a service interruption.

It is important that companies keep their Interruption and Force Majeure contact information up to date with Enbridge Gas at all times. In the event of a contract service interruption or Force Majeure, Enbridge Gas will provide notice to customers using the contact information we have on file. Consider having more than one contact to cover vacations, changes in employment, etc.

Companies can make changes to the contact persons attached to a contract anytime during the year using Enbridge Gas’ online system, or by notifying your customer service representative.
