DR Option – Updates to the Demand Response Option

Publication date: April 15, 2026

In light of Québec's energy context and in order to meet our customers' needs, we are constantly updating our offers. In winter 2026–2027, two versions of the Demand Response (DR) Option will be available: the DR Leeway Option and the DR Commitment Option.

Out of these two offers, the DR Leeway Option provides the most flexibility in terms of participation in peak demand events.

• Customers can select the maximum number of peak demand event hours per winter, ranging from 20 to 100 hours, including or excluding weekend days, based on their ability to reduce their power demand.
• The greater the number of peak demand hours selected, the greater the credit at the end of the winter.
• To be entitled to the credit, customers must participate in at least 50% of the peak demand events, based on the number of hours selected, and provide an effective interruptible power (EIP) of more than 10 kW.

The DR Commitment Option is aimed at customers who are able to commit to reducing their power demand by a predetermined amount.

• Customers can select the maximum number of peak demand event hours per winter, ranging from 20 to 100 hours, including or excluding weekend days, as well as the number of events per day (one or two), based on their ability to reduce their power demand by a predetermined amount.
• The greater the number of peak demand hours selected, the greater the credit at the end of the winter.
• To be entitled to the maximum credit, customers must provide the predetermined interruptible power during all scheduled hours, failing which an optimization charge will apply.
