Watch your savings grow
Rate Flex D can save you quite a bit of money. The price of electricity is below the base rate during 95% of winter, so your savings add up. However, the price of electricity is higher during peak demand events, so your savings could decrease if you don’t take the proper actions.
The trick is to reduce your electricity use during peak demand events, when the price of electricity is higher. This can lead to significant savings during the winter months.

Understanding electricity rates
Rates generally consist of three components that reflect the costs actually incurred in providing electricity service over a given period: namely, the system access charge; energy; and power demand. Here are some details about these concepts to help you better understand your rate.
A set amount, expressed in dollars per month or cents per day, that a customer must pay for their electricity service. For Rate Flex D, it is expressed in cents per day.
The term “system access charge” came into effect on April 1, 2019, replacing the term “fixed charge.”
The amount billed for energy varies based on your consumption.
“Energy” refers to the power used by electrical equipment over a given period of time. Expressed in kilowatthours (kWh), energy is calculated as power, expressed in kilowatts (kW), multiplied by the time during which the power is used, expressed in hours (h).
“Power demand” is not part of Rate Flex D.
Other pricing components that can affect your bill
Two more factors will affect the amount you are billed: the consumption period, and the credit for supply.
Period during which electricity is delivered to the customer and which extends between the two dates used by Hydro‑Québec for calculation of the bill.
Hydro-Québec grants a supply credit of 0.2736¢ per kilowatthour (kWh) to Rate Flex D customers to whom it supplies electricity at 5 kilovolts or higher.
Domestic rates, like the other rates, assume that electricity will be supplied at low-voltage . If you have equipment to step down the voltage of the electricity delivered to you or if you use electricity at medium or high voltage , that means reduced costs for Hydro‑Québec. That’s why we grant you a monthly credit.
