New in 2019
As shown in the table below, Rate D is made up of a system access charge and a variable amount reflecting your energy consumption, divided into two tiers. The first tier (1st tier) is billed at a lower price than the second tier (2nd tier).
More kilowatthours at the lowest price
From 1978 to March 31, 2017, the 1st tier was set at 30 kWh a day, or 900 kWh a month. On April 1, 2017, it was increased from 30 to 33 kWh a day; on April 1, 2018, from 33 to 36 kWh a day; and on April 1, 2019, from 36 to 40 kWh a day. This is advantageous for small consumers, especially low-income households that use electricity for heating.
The 10 kWh a day that have been added to the 1st tier since April 1, 2017, translate into:
- Up to 300 kWh a month billed at a more advantageous rate
- Up to 35% in savings
What’s a kilowatthour?
Structure of Rate D
System access charge per day in the consumption period:
Price of energy for energy consumption up to 40 kilowatthours (kWh) times the number of days in the consumption period (1st tier):
Price of energy for the remaining energy consumption (2nd tier):
Rates in effect April 1, 2019. Under no circumstances shall this table replace the Electricity Rates.
How to read your Rate D bill
Rates generally have three main components that reflect the actual costs incurred by Hydro‑Québec to provide electricity service.
System access charge
The system access charge, expressed in cents per day for this rate, is a set amount you pay for the electricity service itself.
As the amount of energy consumed varies, the cost of energy varies as well.
Since April 1, 2017, Rate D contracts no longer include the billing of power demand. In the interest of simplicity, Rate D, which generally applies to residential and farm customers with a power demand of less than 50 kW, is now based solely on energy consumption in kilowatthours.
If, as a Rate D customer, your maximum power demand is between 50 and 65 kW, it may turn out more advantageous for you to switch to Rate DP.
Details on Rate DP
Electricity rates also include other components.
Credit for supply at medium or high voltage
Hydro‑Québec grants a supply credit of 0.241¢ per kilowatthour to Rate D (residential and farm) 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.
