Electricity rates for Business Customers

Rates that depend on Business Customers' consumption patterns


Base rates

  • Rate G

    Most common rate, which 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 general rate that applies to industrial, commercial and institutional customers (office buildings, hospitals, etc.).

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 general rate that 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 customer-generators whose main energy source is temporarily unavailable or is under maintenance. The electricity purchased is used to replace the energy required for essential loads and auxiliary services.
  • 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 rate option allows you to use, during Hydro-Québec’s off-peak hours, a small amount of electricity beyond your regular consumption at Rate M or G-9 to fulfill a short-term order or meet an exceptional need. More specifically, it is designed 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 around 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 around the associated constraints.
  • Running-In of New Equipment by medium-power customers

    If you have to run short tests before putting new equipment into service, your power demand may rise. With the running-in option, you are temporarily exempted from some rate conditions applicable to billing.
  • Net Metering Option for a Rate G customer-generator

    Are you a customer-generator? This rate option allows you to feed your surplus power into the Hydro-Québec grid in exchange for kilowatthour credits.
  • Interruptible Electricity Options for medium-power customers

    With this rate option, Hydro-Québec offers you credits in exchange for curtailing your electricity consumption on request.
  • Sentinel lighting rate

    The Régie de l’énergie has approved the phase-out of Sentinel lighting service, starting April 1, 2013.
  • Equipment testing by medium-power customers

    If you have to run short tests after adding new equipment or after modifying or optimizing existing equipment, your power demand may rise temporarily. With this option, you don’t have to pay for the resulting increase in your power demand during the test period(s).

Does your business run a farm, residential buildings or multiunit residential buildings?

Do you run a big business with a minimum billing demand of 5,000 kW or more?
