The Winter Credit Option is added to your base rate, Rate D.

Structure of Rate D

System access charge for each day in the consumption period 43.505¢

Price applicable to remaining energy consumed (2^nd tier) 10.041¢/kWh

Structure of Winter Credit Option

Credit for every kilowatthour curtailed (minimum of 2 kWh per event) during peak demand events 53.526¢/kWh

Rates in effect April 1, 2023. This table does not replace the Electricity Rates document in any way whatsoever.

Understanding rates

Rates generally have three main components that reflect the actual costs incurred to provide electricity service.

System access charge

Amount you pay for service. At Rate D, it is expressed in cents per day.

Energy

You are billed for the amount of energy you actually use.

Power demand

“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 0.2579¢ per kilowatthour (kWh) to Rate D customers to whom it supplies electricity at 5 kilovolts (kV) or higher.

Hydro‑Québec's 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.

How to request electricity service

Peak demand event

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.

Curtailed energy

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.

Reference energy

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.

Energy

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).

Winter period

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.

Rate

Electricity rate effective April 1, 2023.

Low voltage: Voltage of 750 V or less.

Medium voltage: Voltage of more than 750 V, but less than 44 kV.

High voltage: Voltage of 44 kV or more.

Voltage

Difference in electrical level between two points, expressed in volts (V).
