For each consumption period, the total applicable credit is calculated by adding:
Note: To receive the full credit, you must fulfill the commitment you made under the DR Option. If you do not fulfill your commitment, a charge (penalty) will be deducted from the credit.
AN IMPORTANT BASIS FOR CALCULATION
The power demand reduction goal (or interruptible power goal) refers to the number of kilowatts (kW) that your company undertakes not to consume during a peak demand event. This goal is determined when you sign up for the DR Option, based on your company's capabilities and the target potential reduction.
To help companies keep track of this goal, we provide them with a power demand threshold each month, which they must not exceed during an event.
To help companies meet their demand reduction goal, we calculate a power demand threshold for them every month. We start with the usual maximum power demand for the month and subtract the company's power demand reduction goal, to obtain the threshold that must not be exceeded that month during a peak demand event.
Maximum power demand for the current month (kW) – 95 % of the reduction goal (kW) = Power demand threshold (kW)
You will still receive the fixed credit, but it will be reduced in accordance with the applicable terms and conditions.
Not while the agreement is in effect, during the winter period.
The fixed credit is the credit applied to your bill in exchange for your commitment to reduce your power demand. It is offered in combination with the variable credit.

The fixed credit is the product of the power demand that you committed to curtail and the amount of the credit per kilowatt, based on the sub-option you selected.
The total credit is applied to your bills for the winter period.
Power demand reduction goal (kW), if met, × fixed credit per kilowatt ($/kW) = fixed credit amount ($)
Signing an agreement for more than one year gives you access to the multi-year commitment credit.
Note: If the agreement is terminated before it ends, an early termination charge will be deducted from the credit.

Hypothetical example
The variable credit is the incentive offered in exchange for the energy curtailed during peak demand events. It is added to the fixed credit and is calculated for each billing period.
This credit varies based on the maximum number of peak demand events included in the sub-option selected.
First peak demand event with overrun
$0.05/kWh
Second peak demand event with overrun
$0.35/kWh
Energy curtailed during the peak demand events that took place in the last billing period (kWh) × credit per kilowatthour ($/kWh) = amount of the variable credit ($)
No. An agreement cannot be modified before it expires, at the end of the winter period. The number of maximum peak demand events per day is based on the sub-option you selected. You can only change your sub-option when you renew your enrollment in the DR Commitment Option, should you choose to do so.

Hypothetical example
Credit for a notice that is shorter than the one provided for, paid after each relevant consumption period and calculated as follows :
If a company doesn't meet the agreed-upon reduction goal, or if it terminates an agreement before it expires, a charge is deducted from the applicable credit. However, this charge is capped.
During a peak demand event, consumption is recorded every 15 minutes. If a company exceeds its maximum power demand threshold during the event, the overrun will count for 1 hour, and a charge will be deducted from the credit.
According to the applicable terms and conditions, the amount deducted cannot exceed the maximum deduction set for a peak demand event, and the sum of overrun deductions for a given winter period cannot exceed the cap determined for the season.

The lowest of the two amounts applies.
The penalties for peak demand events are added together until the maximum penalty amount per peak demand event is reached. The penalty per event is deducted from the fixed credit, which is still applied to the customer's bill.
A maximum penalty for the season is also provided for. This corresponds to 150% of the fixed credit. This maximum penalty is also applied in the event of early withdrawal from a multi-year agreement.
If a company decides to terminate their multi-year commitment before it expires, Hydro‑Québec deducts an amount equal to 50 % of the credits calculated for the year of termination, multiplied by the number of years remaining in the commitment.

In 2025, a company that was signed up for the DR Commitment Option, with a three-year agreement and a fixed credit estimated at $100,000 per year, ends its agreement after the first year.
The applicable deduction is 50% of the credit calculated for the two remaining years, so a total of $100,000 for 2026 and 2027.
The deduction affects only the fixed credit. The variable credit is not included in the calculation. The company keeps the amounts linked to the fixed credit accumulated in the first year, and will not accumulate any further amounts in subsequent years, since it is no longer participating in peak demand events.
