## A great rate for small-power customers

Rate G is generally made up of three components: a system access charge, energy consumption and billing demand. It is a monthly rate, which means it is based on a 30‑day period.

In general, the billing period is about 2 months, or about 1 month if there is a charge for billing demand.

## Structure of Rate G

• System access charge for a 30‑day period, prorated to the exact number of days in the consumption period: \$13.648
• Price of energy for a 30‑day period
First 15,090 kilowatthours (kWh):
10.959¢/kWh
• Remaining energy consumed: 8.435¢/kWh
• Price of power demand for a 30‑day period
First 50 kilowatts (kW):
not billed
• Power demand exceeding 50 kW: \$19.526/kW

If little or no electricity is used, a minimum charge is billed. It is \$13.648 per month (30 days) when single-phase electricity is delivered or \$40.944 per month when three-phase electricity is delivered.

Rates in effect as of April 1, 2023. This table does not replace the Electricity Rates publication in any way whatsoever.

## Credit for supply at medium or high voltage

Hydro‑Québec’s rates assume that electricity will be supplied at low voltage. 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.

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 18.971¢ per kilowatt (kW) on the billing demand.

For more details about Rate G, consult Section 1 of Chapter 3 of the Electricity Rates [PDF 4.75 MB].

## Separate metering

Method of measuring energy consumed with a separate meter for each residential or commercial unit in a building.

## Bulk metering

Method of measuring energy consumed with a single meter instead of separate meters for an entire multiunit commercial or residential building. The building owner is responsible for dividing the costs between the occupants.

## 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).

## Minimum billing demand (minimum demand)

The minimum amount of power that the customer must pay for each consumption period, regardless of electricity use. The threshold is set so that you pay your share of the costs Hydro-Québec incurs to meet your power needs at all times. The minimum billing demand is determined by the conditions of each rate, as indicated in the Electricity Rates.

• For all rates except Rate L, the minimum billing demand is automatically determined based on the previous winter’s maximum power demand.
• Rate L customers must set their own minimum billing demand, called “contract power,” based on the amount of electricity they expect to use.

## 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.

## 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).

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

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.

## Monthly periods

Period of 30 days, which may begin on any day of the month, established by Hydro-Québec for billing purposes.

## Minimum charge (minimum monthly bill)

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

## System access charge

A set amount, expressed in dollars per month or cents per day depending on the rate, to be paid monthly the electricity service itself.

The expression “fixed charge” has been replaced by “system access charge” as of April, 2019.

• Low voltage: Voltage of 750 V or less.
• Medium voltage: Voltage of more than 750 V, but less than 44 kV.
• High voltage: Voltage of 44 kV or more.

## Voltage

Difference in electrical level between two points, expressed in volts (V).

## Transformation

Operation that involves increasing or decreasing voltage through a transformer.
