What is dual-energy?
Dual-energy uses two complementary energies for heating: electricity as the main source for most of the year and natural gas as a backup source during extremely cold weather1.
This energy solution is available for residential customers (condo, single-family home, duplex and triplex), multi-residential customers and business customers.
It lets you use the right energy, at the right time and at the best cost.
3 reasons to choose dual-energy

Optimize your energy budget
By taking advantage of special electricity rates2 (dual-energy rate from Hydro-Québec or your electricity provider), you could enjoy significant savings on your energy bills3.
For individuals, this rate is usually not restricted to heating and applies all year round on all electrical devices, so it can be beneficial for other uses, such as charging an electric vehicle or running an air conditioner in summer.

Access attractive grants
The Quebec government, Hydro-Québec and Énergir have joined forces to offer you a grant that can cover up to 80%4 of the additional costs associated with the purchase and installation of new dual-energy equipment.
Some municipalities offer additional subsidies, to make your conversion to dual-energy even easier. Find out more from your municipality!

Contribute to the energy transition
By switching from a heating system that uses only fossil fuel to a dual-energy electricity–natural gas system, you will be actively helping to reduce greenhouse gas (GHG) emissions. You will be helping Énergir, your municipality and all of Québec meet the ambitious challenge of decarbonization.
