Potential savings

By taking advantage of the equipment testing conditions, Rate L or LG customers can be temporarily exempted from certain conditions that apply to excess power demand.

Flexible terms and conditions

To benefit from these conditions, you must advise Hydro‑Québec in advance of the testing start date and duration.

The equipment testing conditions can apply for a minimum of 1 hour and a maximum of 1 consumption period.

Calculation of billing amount

Rates L and LG apply to the billing demand for periods with no testing and to the energy for the consumption period in question.

In addition, for each 15-minute integration period of actual hours in the test period(s), an amount of 10¢ per kilowatthour is applied to the excess of real power demand over the billing demand for periods with no testing.

For more information

If you have any questions about this rate option, contact your commercial officer or designated agent. You can also reach our Business customer services at 1 800 463‑9900 or by e-mail at affaires@hydro.qc.ca.

These explanations have been simplified. For more details about the testing equipment option for medium‑power customers, consult section 7 of chapter 5 of the Electricity Rates [PDF 4.54 Mb], approved by the Régie de l’énergie.

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 calculation of the bill.

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).

Real power

Amount of electricity consumed in a useful manner to operate equipment, such as a motor or a heating or lighting system. Real power is expressed in kilowatts (kW).
