Take advantage of replacement of your heating or air conditioning system to convert to dual-energy. You could benefit from major grants allowing you to cover a significant portion of the conversion costs and take advantage of savings linked to Hydro-Québec’s dual-energy rates1. You'll also take an action that contributes to reduce greenhouse gas emissions.
This offer is only available in the Greater Montréal area.
A dual energy system is the combination of two energy sources to ensure your heating needs in your residence. The system uses a fossil fuel (natural gas) to meet your heating needs during very cold weather (usually below –12 °C or –15 °C). When the temperature is not as cold, the electrical system takes over to heat your residence. Everything is managed automatically by installing a smart thermostat and a temperature sensor. Hydro-Québec’s dual-register meter measures your consumption and allows you to benefit from the dual energy rate (DT), when you consume electricity outside cold periods.
Your dual-energy system may vary depending on the type of heating equipment in your residence. If you have a forced air system, dual-energy requires the combination of a natural gas furnace and a heat pump. For hot water systems, dual-energy combines a natural gas boiler and an electric boiler.
Natural gas furnace and water heater
Natural gas furnace combined with a heat pump
Installation of an electric water heater is recommended
Natural gas boiler and water heater
Natural gas boiler combined with an electric boiler
Installation of an electric water heater is recommended
The price of electricity at the dual-energy rate varies according to the temperature.
Price of energy consumed when the temperature is equal to or greater than –12°C or –15°C: 4.818 ¢/kWh
Price of energy consumed when the temperature is lower than –12°C or –15°C and you use natural gas for heating: 28.173 ¢/kWh
