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.
