If your farm is equipped with one or more dual-energy systems and your electricity service contract is eligible for Rate D or Rate DM, you could benefit from an overall lower rate, Rate DT, if you meet the eligibility criteria. Under this rate, pricing varies according to the temperature.
A dual-energy heating systems uses two energy sources:
electricity as the main source, i.e., when the outdoor temperature is above or equal to −12°C or −15°C, depending on the climate zones defined by Hydro-Québec, and
fuel as a source of backup heating, when the temperature drops below that level.
Energy consumed when the temperature is above or equal to −12°C or −15°C, depending on the climate zones defined by Hydro-Québec:
Energy consumed when the temperature is below −12°C or −15°C, as applicable:
Charge for demand exceeding the greater of 50 kilowatts (kW) or 4 times the multiplier:
In winter :
In summer :
Energy, expressed in kilowatthours (kWh), is the power used by electrical equipment over a given period of time. It is calculated as power (wattage), expressed in watts (W), multiplied by the time during which it is used, expressed in hours (h).
Eligibility criteria for Rate DT – Dual energy for farms
When a distribution service loop serves a farm or both a farm and a dwelling, Rate DT applies if the following conditions are met:
This distribution service loop must supply at least one dual-energy system.
The capacity of each dual-energy system in fuel mode must be sufficient to heat the premises in question. The energy sources of the dual-energy system must not be used simultaneously.
The installed capacity of each dual-energy system must be no less than 50% of the installed capacity of the premises it serves.
Each dual-energy system must be equipped with an automatic switch permitting transfer from one source of energy to the other.
The automatic switch must be connected to a temperature gauge supplied and installed by Hydro-Québec in a location and under conditions determined by Hydro-Québec. The gauge indicates to the automatic switch when a change of operating mode is required in view of the outdoor temperature. The fuel mode is used when the outdoor temperature is below −12°C or −15°C, depending on the climate zones defined by Hydro-Québec.
You may also use a manual switch to change from one source of energy to the other.
The installed capacity of all premises supplied by this distribution service loop that are not served by a dual-energy system must not exceed 10 kilowatts.
