Generally speaking, Rate D is for residential use where each dwelling has its own separate electricity meter.

Rate D consists of a fixed charge plus two levels of pricing for energy consumption. The structure of Rate D is as follows:

Rates effective April 1, 2008.
Under no circumstances may this table be used to replace the Distribution Tarif.

Energy prices may be reduced by a discount for electricity supplied at medium or high voltage.

Rate D also applies when electricity is delivered to:

• Apartment buildings (with separate meters);
• Community residences containing dwellings (with separate meters);
• Rooming houses (9 rooms or less);
• Community residences (9 rooms or less);
• Tourist lodgings (9 rooms or less);
• Foster families or foster homes (9 persons or less);
• Residential outbuildings: any building or installations appurtenant to a residential building, except on farms:
• used exclusively by the persons occupying the dwelling or apartment building;
• designated exclusively for uses connected with the dwelling or apartment building.
• Dwellings where some of the electricity is used for other than domestic purposes (installed capacity no more than 10 kW);
• Farms: land, buildings and equipment used for growing crops or raising animals.

Rate D, like the other rates, assumes that electricity will be supplied at low voltage. When the customer uses electricity supplied at a nominal voltage between phases equal to 5kV but less than 50 kV or invests to transform it, then Hydro-Québec no longer has to pay transformation costs. In return, the utility grants a discount of 0.222 ¢/kWh on the price of energy billed.
