Other rates

Rate G‑9

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.

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.

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.

Equipment testing

Option 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.
