Important information for Rate G customers with billing demand

For your service contract to qualify for Rate M, your maximum power demand must have reached 50 kW or more at least once in the past 12 billing periods. We suggest that you check your consumption history regularly because changing to Rate M could become worthwhile for you.

Deciding whether it would be better to switch to Rate M

Look at your statement

Every month, your detailed statement breaks down your energy costs in terms of power (kW) and consumption (kWh). Your consumption history, shown at the bottom or overleaf, helps you decide whether it's time to think about switching to Rate M. Here's how:

Add up the kWh column on your last detailed statement to determine your total annual energy consumption. Always look at the history of the past 12 months. If the total is 100,000 kWh or more, Rate M may be the best solution for you.

Are changes coming to your business?

If you plan to buy new equipment, extend your business hours or enlarge or renovate your facility, your use of electricity could increase and it could then be to your advantage to switch to Rate M.

Understanding rates

Rates have three main components that reflect the actual costs incurred by Hydro-Québec to provide electrical service.

The fixed charge, expressed in $ per month, is the amount you pay for the service itself, apart from any consumption.

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

Hydro-Québec must be able to meet its customers’ maximum power demand at all times. Even if is variable and consumption is sometimes minimal, Hydro-Québec’s rates still have to cover the cost of operating and maintaining the power system. For this reason, it’s important that rates for large electricity consumers include billing for maximum power demand. This reflects the costs associated with meeting power demands of varying size and duration.

Your billing demand, for purposes of applying the demand charge, is the greater of these two values:

  • Maximum power demand, which is to the greater of the following two values:


  • or



In the case of Rate G, the demand charge only applied to consumption over 50 kW. The minimum billing demand is equal to 65% of the during a consumption period that falls wholly within the period included in the 12 consecutive monthly periods ending with the consumption period in question.


Electricity rates also include other components.

Hydro-Québec's rates assume that electricity will be supplied at low . If you have equipment to step down the voltage of the electricity delivered to you or if you use electricity at medium or high voltage, that means reduced costs for Hydro-Québec. In return, you receive a monthly credit on your demand charge. The credit is determined according to the supply voltage.

Nominal voltage between phases equal to
or greater than Monthly credit

5 kV, but under 15 kV $0.612/kW
15 kV, but under 50 kV $0.981/kW
50 kV, but under 80 kV $2.190/kW
80 kV, but under 170 kV $2.679/kW
170 kV $3.540/kW

Rates in effect April 1, 2017. Under no circumstances shall this table replace the Electricity Rates.

Hydro-Québec bills you only for the electricity you use, regardless of where it is metered in relation to the transformer substation. If metering occurs before transformation, the electricity billed will include transformation losses. So that you do not pay for losses, Hydro-Québec grants an adjustment of on the billing demand. Conversely, if metering occurs after transformation, the company will absorb the losses.
