Understanding rates

Rates have three main components that represent the cost categories of electrical service. In this way, rates reflect the cost of meeting customer electricity demand.

The fixed charge is unaffected by electricity consumption. It is set in relation to the fixed costs of providing electrical service, such as installing and reading the meter, metering, billing, collections and certain distribution system costs.

The fixed charge is also determined by the number of contracts at each rate.

As the amount of consumed varies, the cost of energy varies as well.

Basing billing solely on kilowatthours used wouldn’t be fair, since it wouldn’t account for the differences in cost, which can vary by the amount and duration of .

Hydro-Québec equipment must be able to meet each customer’s yearly maximum power demand. Even if power demand is variable and consumption is sometimes minimal, Hydro-Québec must always cover the costs related to the proper operation and maintenance of the equipment it uses to supply its customers’ installations.

Calculating billing demand

The demand charge is applied to the greater of these two billing demand values.

  • The maximum power demand corresponding to the greater of the two following values:

    • ;
  • or



For Rate D, the minimum billing demand is set at 65% of the during a consumption period that falls wholly within the winter period included in the 12 consecutive monthly periods ending with the consumption period in question.


Electricity rates also include other components.

Hydro-Québec grants a supply credit * to domestic rate (residential and agricultural) customers to whom it supplies electricity at 5 kV or higher.

Rates D, DT and DM, like the other rates, assume that electricity will be supplied at low . Customers who have equipment to step down the voltage of the electricity they are supplied or wish to use medium- or high-voltage electricity represent reduced costs for Hydro-Québec. In return, they are granted a monthly credit.
