Rates in effect April 1, 2019. Under no circumstances shall this table replace the Electricity Rates.
Rates generally have three main components that reflect the actual costs incurred to provide electrical service.
System access charge
Amount you pay for service. At Rate D, it is expressed in cents per day.
You are billed for the amount of energy you actually use.
“Power demand” is not considered in Rate D with Winter Credit Option.
Electricity rates may also include other components
Credit for medium- or high-voltage supply
Hydro‑Québec grants a supply credit of 0.241¢/kWh to Rate D customers to whom it supplies electricity at 5 kilovolts or higher.
The domestic rates, like the other rates, assume that electricity will be supplied at low voltage. Customers who have equipment to step down the voltage of the electricity they are supplied, or who use electricity at medium or high voltage, represent reduced costs for Hydro‑Québec. In return, they are granted a monthly credit.
Estimate savings and sign up
Log into your Customer Space to find out how much you could save and to sign up for the Winter Credit Option or Rate Flex D.
A time period during which Hydro‑Québec has determined that electricity demand will be very high. There may be 25 to 33 events per winter, at most, for a maximum of 100 hours in all.
Difference between the kilowatthours (kWh) usually consumed in peak hours (reference energy) and those consumed during a peak demand event (actual consumption). You must curtail at least 2 kWh per event to be eligible for a credit.
Estimate of electricity usually used, determined by adding up the average number of kilowatthours recorded for the same times of day during the reference period and adjusting for the temperature. Averaging excludes minimum and maximum values in each hour.
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).
The formula for energy is as follows: energy (in kilowatthours) is equal to power (in kilowatts) multiplied by duration of use (in hours).
Energy (kWh) = power (kW) x time used (h).
Period from December 1 through March 31 of the next year, inclusive.
System access charge
A set amount, expressed in dollars per month or cents per day depending on the applicable rate, that the customer must pay for the electricity service.
Beginning April 1, 2019, the term fixed charge was replaced with system access charge.
Electricity rate as at April 1, 2019.
Low voltage: Voltage of 750 V or less.
Medium voltage: Voltage of more than 750 V, but less than 44 kV.
