Electricity rates for Business Customers

Which rate you pay depends on your consumption pattern


Base rates

  • Rate G

    Most common rate; applies to customers whose is under 65 kilowatts (kW).
  • Rate M

    Rate that applies to customers whose has exceeded 50 kW at least once in the last 12 billing periods. This is the rate that generally applies to medium-power customers such as office buildings and hospitals.

Rates and options for special needs

  • Rate G-9

    Rate that applies to customers whose has exceeded 65 kW at least once in the last 12 billing periods. This is the rate that generally applies to companies with equipment that uses a significant amount of electricity over short periods (e.g., pumps for golf courses, chair lifts).
  • Rate GD

    Rate that applies to medium-power contracts. This is an optional rate offered on backup power sold to independent producers whose main generating source is temporarily unavailable or under maintenance. The electricity purchased is used to replace the energy required for the independent producer’s essential loads and auxiliary services.
  • Experimental Rate BR

    Experimental Rate BR applies to contracts for electricity supplied to one or more electric vehicle DC charging stations rated 400 volts or more. It can also apply to a contract for electricity supplied to one or more 240-V charging stations.
  • Economic Development Rate for medium-power customers

    The Economic Development Rate applies to customers who undertake to build and commission a new facility with a power demand of at least 1,000 kW or to add at least 1,000 kW of demand to an existing facility.
  • Additional Electricity Option for medium–power customers

    This option allows customers to use, in Hydro-Québec’s off-peak hours, electricity beyond their normal consumption at Rate M or G-9 to fill a short-term order or meet an exceptional need. More specifically, it’s for customers who are able to adjust their production and to manage their electricity consumption in such a way as to reap the benefits of the additional electricity option while working with the associated constraints.
  • Additional Electricity Option for Photosynthetic Lighting

    This rate option is designed for agricultural customers who use part of the electricity supplied by Hydro-Québec for photosynthetic lighting. More specifically, it targets customers who are able to adjust their production and to manage their electricity consumption in such a way as to reap the benefits of the additional electricity option while working with the associated constraints.
  • Interruptible Electricity Options for medium-power customers

    With these rate options, Hydro-Québec offers its customers credits in exchange for curtailing their electricity consumption at its request.
  • Running-In of New Equipment by medium-power customers

    A customer who wishes to put new equipment into service or commission a new plant may see its power demand rise temporarily. This option allows this customer to be temporarily exempted from some rate conditions applicable to power billing.
  • Equipment testing by medium-power customers

    A customer who wishes to run short tests after adding new equipment or modifying or optimizing existing equipment may see its power demand rise temporarily. This option allows this customer not to pay for the resulting increase in its power demand during the period(s) in question.
  • Public lighting rates

    Public lighting service is offered to federal, provincial and municipal authorities, or to any person duly authorized by them.
  • Net Metering Option for a Rate G customer-generator

    This rate option allows a customer-generator to feed its surplus power into the Hydro-Québec grid in exchange for kilowatthour credits.
  • Sentinel lighting rate

    The Régie de l’énergie has approved the phase-out of Sentinel lighting service, since April 1, 2013.
