Potential savings

The Rate M and Rate G-9 Equipment Testing Option allows you to test equipment without being billed for the excess power used during the test period(s).

Flexible conditions of application

To take advantage of this option, you must advise Hydro-Québec before the first consumption period during which you plan to run the tests. You’ll have to submit information about the nature of the new equipment, modifications or optimization work, as well as the power rating of the equipment to be tested.

The Equipment Testing Option can apply for one to three consumption periods.

Calculation of billing amount

For each consumption period when tests are run, Rate M or Rate G-9 (as the case may be) is applied to the highest billing demand during the last 12 consumption periods as well as to the energy consumed during the period in question.

In addition, an amount of 10¢ per kilowatthour is applied to the difference, if positive, between the energy consumed during the consumption period in which tests are run and the energy consumed during the period with the highest billing demand as specified above.

Power demand

Power a customer requires to meet energy needs at a given time. The higher the customer’s energy consumption at a given time, the higher the power demand.

Consumption period

Period during which electricity is delivered to the customer and which extends between the two dates used by Hydro-Québec for the calculation of the bill.

Power

Total amount of electricity supplied at a given time. Expressed in kilowatts (kW), power is the combined effect of voltage, expressed in kilovolts (kV), and current, expressed in amperes (A).

Energy

Power used by electrical equipment over a given period of time. Expressed in kilowatthours (kWh), energy is calculated as power, expressed in kilowatts (kW), multiplied by the time during which the power is used, expressed in hours (h).
