Rate BR for charging stations

Experimental Rate BR applies to a contract for electricity delivered for the purpose of supplying one or more direct-current electric vehicle charging stations rated 400 volts or more. It can also apply to a contract for electricity supplied to one or more 240 volts stations.

To take advantage of experimental Rate BR, you must meet the following conditions:

  • If you have several direct-current charging stations rated 400 volts or more, which are installed at the same site, they must come under a single contract.
  • If the electricity is used for a purpose other than supplying electric vehicle charging stations, such as lighting for example, Rate BR applies on condition that the installed load for purposes other than electric vehicle charging does not exceed 10 kilowatts.
  • You must agree to supply Hydro‑Québec with non-identifiable data from all charging stations covered by the contract under this rate, such as duration, energy consumption and power demand for each charge.

Rate G cannot be applied to a contract supplying fast‑charge stations. However, Rate G9 or M could apply if the number of charging operations increases and they become more advantageous for you.

Installed load

Sum of the nameplate ratings of a customer’s electrical equipment.


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).

The formula for energy is as follows: energy (in kilowatthours) is equal to power (in kilowatts) multiplied by duration of use (in hours).

Maximum power demand

Maximum power measured during a consumption period. It is the higher of the following two values: real power in kilowatts (kW), or a percentage (90% for domestic rates and small- and medium-power rates, or 95% for large‑power rates) of the apparent power in kilovoltamperes (kVA).

Load factor (LF)

Relationship between the energy (in kilowatthours) actually consumed and the amount of energy that can be consumed by using the entire maximum power demand throughout the consumption period. The load factor indicates the utilization rate of maximum power demand for a given consumption period.

Minimum charge (minimum monthly bill)

Minimum amount billable for electricity service even if little or no electricity has been used in the billing period.

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.
