Rate that applies to a contract whose maximum power demand has been at least 50 kilowatts (kW) during a consumption period included in the last 12 monthly periods.
Rate that applies to an annual contract whose contract power is 5,000 kilowatts (kW) or more and which is principally related to an industrial activity.
Rate that applies to an annual contract whose minimum billing demand is 5,000 kilowatts (kW) or more and which is not principally related to an industrial activity.
Rate that applies to large- or medium‑power customers whose power demand is limited. This rate can be advantageous for companies with equipment that uses a significant amount of power over short periods — for example, golf course irrigation pumps or ski hill snow cannons.
Optional medium‑power rate offered on backup power Hydro‑Québec sells to independent producers whose main generating source is temporarily unavailable or under maintenance. The electricity purchased is used to power essential loads and auxiliary services.
Experimental Rate BR
Rate that applies to contracts for electricity supplied to one or more electric vehicle charging stations rated 400 volts DC or more. It can also apply to a contract for electricity supplied to one or more 240-V charging stations.
Public lighting rates
General electricity rates that apply to the public lighting service offered to federal, provincial and municipal authorities or to any person duly authorized by them.
Sentinel lighting rates
Lighting rates for the supply, operation and powering of Sentinel photoelectric‑cell luminaires. These luminaires are the property of Hydro‑Québec and are used for outdoor lighting, but not for public lighting. Hydro‑Québec has been gradually phasing out these rates since April 1, 2013.
Rate options and conditions
Economic Development Rate
Rate that entails a rate reduction for large- or medium‑power customers (Rates M, G‑9, L or LG) who undertake to build and commission a new facility with a power demand of at least 1,000 kW or to add at least 500 kW of power demand to an existing facility.
Industrial Revitalization Rate for large‑power customers
Under this new rate, which came into effect on April 1, 2018, Rate L customers can benefit from an advantageous price to return unused production capacity to operation or to convert an industrial process that is currently powered by fossil fuel to electricity.
Additional electricity option
Option that allows large- or medium‑power customers (Rates M, G‑9, L or LG) to use electricity beyond their normal consumption during Hydro‑Québec’s off-peak hours to fill a short-term order or meet an exceptional need.
- Additional electricity option – medium‑power customers
- Additional electricity option – large‑power customers
Interruptible electricity options
Rate options where Hydro‑Québec offers credits to large- or medium‑power customers (Rates M, G‑9, L or LG) in exchange for curtailing their electricity consumption at its request.
- Interruptible electricity options – medium‑power customers
- Interruptible electricity options – large‑power customers
Running-in of new equipment
Options available to large- or medium‑power customers (Rates M, L or LG) wishing to put new equipment into service, which can result in a higher power demand for a few months until their operations have been optimized. Under this option, such customers can be temporarily exempt from certain rate conditions applicable to power demand billing.
- Running-in of new equipment – medium‑power customers
- Running-in of new equipment – large‑power customers
Equipment testingOption available to large- and medium‑power customers (Rates M, G‑9, L or LG) who need to run short tests after adding new equipment or modifying or optimizing existing equipment, a situation that risks temporarily increasing their power demand. This option allows the equipment to be tested without the customer being billed for the excess power used during the test period(s).
Additional Electricity Option for photosynthetic lighting
Option targeting greenhouse growers (Rate DP, M or G‑9) who use part of the electricity supplied by Hydro‑Québec for photosynthetic lighting. More specifically, it targets customers whose maximum power demand has been at least 300 kilowatts (kW) during a consumption period included in the 12 consecutive monthly periods preceding the date of the sign up request.
Net Metering Option for a Rate G customer-generator
Rate option that allows a Rate G customer-generator to feed its surplus electricity back into the Hydro‑Québec grid in exchange for credits applied to the electricity bill.
