Dual energy for sustainable decarbonization

Electricity and natural gas: Two energy sources for heating at the lowest possible cost!

Hydro‑Québec has joined forces with Énergir and Enbridge Gaz Québec to fight climate change by proposing a dual‑energy offer. The idea is simple: using electricity to meet over 70% of heating requirements and natural gas as an auxiliary source. Find out more about this collaborative effort.

Who is the offer geared to?

Énergir and Enbridge Gaz Québec residential customers with natural gas central heating systems who want to lower both their energy bills and their greenhouse gas (GHG) emissions.

What does the offer consist of?

The dual‑energy offer meets building heating requirements through a combination of two energy sources: electricity for the most part, and natural gas during periods of extreme cold, when pressure on the power grid is at its highest. In other words, it consists in using the right energy source at the right time and at the lowest possible cost. It’s win‑win all around, since it benefits not just customers, but society as a whole!

Benefits for you...

By opting to convert to a dual‑energy (electricity and natural gas) heating system, you’ll enjoy:

  • Access to financial assistance covering a significant portion of the purchase and installation costs of the dual‑energy heating system

  • Recurring savings on your energy bill, largely thanks to Hydro‑Québec’s advantageous Rate DT

  • Support throughout the conversion process

  • As needed, work to adapt Hydro‑Québec’s distribution system, performed at no charge to you

... and for society

You’ll also help:

  • Fight climate change by using electricity produced from clean and renewable energy sources to meet most of your heating needs

  • Reduce pressure on the power grid by using natural gas as your heat source during winter peaks

Financial assistance

Substantial financial assistance is provided under a partnership between the Québec government and Hydro‑Québec, as part of the Chauffez vert program, in collaboration with Énergir and Enbridge Gaz Québec for the purchase and installation of a dual‑energy system. There are two scenarios:

Forced‑air central heating system

You are eligible for financial assistance if you add an electric central heat pump to your natural gas heating system, regardless of whether or not you decide to replace your gas boiler at the same time.

For detached, semi‑detached or row houses or condo units with a separate heating system, financial assistance of $7,300 is available for Énergir customers and $6,800 for Enbridge Gaz Québec customers.

Duplex or triplex: financial assistance is also available.

Hot water heating system

Financial assistance is available to switch to a dual‑energy (electricity and natural gas) heating system in a detached, semi‑detached or row house, a condo unit with a separate heating system, or a duplex, triplex or other multi‑unit building.


How can you take advantage of this offer?

  1. Contact your natural gas supplier.

    You’ll receive full support throughout the conversion to dual energy.

  2. Obtain bids.

    Specialized contractors will submit bids that include the financial assistance for which you are eligible.

  3. Have your equipment installed.

    The selected contractor will contact you to book an installation date.

  4. Save money as you reduce your heating footprint!

    You'll benefit from Hydro‑Québec's Rate DT and tips on how to maximize your savings.

Join in the fight against climate change by helping Québec reach its GHG emissions reduction targets!

Hydro‑Québec’s partnerships with Énergir and Enbridge Gaz Québec aim to significantly reduce greenhouse gas (GHG) emissions at the best possible cost for Québec society by letting you use the right energy source at the right time.

Reduction of 540,000 tonnes of CO2 equivalent per year by 2030,

or roughly the emissions from 125,000 vehicles*


* Calculation based on average fuel consumption of 10.7 L/100 km for a vehicle traveling 20,000 km annually.

More specifically, it maximizes the amount of electricity used to heat buildings while cutting the natural gas consumption of participating households by over 70%. The two energy sources work together to optimally meet energy needs during cold snaps.

In fact, if heating were to be 100% electrified, this would add nearly 2,000 megawatts (MW) to peak demand by 2030, which is more than the capacity of all four generating stations in the Romaine complex! Dual energy makes it possible to lower electricity demand at the very moments when the grid is subject to the most pressure. This in turn helps Hydro-Québec avoid having to make additional investments or expenditure to meet peak demand.

This solution thus represents a concrete means of acting now to fight climate change while limiting the impact on the environment and society.
