Hydro‑Québec and Énergir have joined forces to fight climate change by proposing a dual‑energy building heating offer.

This new offer will go a long way to electrify a large part of building heating without increasing the demand for electricity during peak winter periods.

How? The dual‑energy solution combines two energy sources: electricity for the most part and natural gas when it’s especially cold and the demand for electricity is high. The solution uses the right energy source at the right time and at the lowest possible cost. Find out more about this collaborative effort.

Who is the offer geared to?

Énergir business and institutional customers with a natural gas central heating system who want to lower their energy bills and their GHG emissions.

You use two energy sources but are not an Énergir customer?
Although you are not eligible for this offer, you can benefit from Hydro‑Québec’s dual‑energy rate.

What does the offer consist of?

Substantial financial assistance to purchase and install a dual‑energy heating system is provided under a partnership between the Québec government, Énergir and Hydro‑Québec.

Benefits for you...

By opting for a dual‑energy (electricity and natural gas) heating system, you’ll benefit from:

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

Support throughout the conversion process

Work performed to adapt Hydro‑Québec’s distribution system at no charge to you (as needed)

…and for society

You’ll also help:

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

Reduce the pressure on Québec’s power grid by heating with natural gas during winter peaks

Financial assistance

In addition to recurring average annual savings of 15% on your energy costs with Hydro‑Québec’s new dual-energy rate, you could receive significant financial assistance to purchase and install a dual‑energy heating system through a partnership between the Québec government, Énergir and Hydro‑Québec.

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

The partnership between Hydro‑Québec and Énergir aims 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 customers by over 70%. The two energy sources work together to optimally meet energy needs during peak winter periods.

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 will therefore help us meet peak demand during peak periods while keeping costly purchases of fossil‑fuel generation on neighboring markets to a minimum, and thus limit pressure on electricity rates for all customers.

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

Frequently asked questions

When will this offer be rolled out?

Commercial and institutional customers will have access to this offer as of November 6, 2023.

Who is eligible for this offer?

The dual‑energy offer for sustainable decarbonization is aimed at business and institutional customers who use natural gas as their main source of energy for heating.

I have an electric heating system. Am I eligible for this offer?

No. The offer for the purchase and installation of a dual-energy heating system is aimed at eligible Énergir customers who currently use natural gas for their space heating needs to encourage them to adopt dual energy by combining electricity and natural gas for the sustainable decarbonization of Québec.

Customers who are interested in dual energy but currently use another eligible fuel can take advantage of other options, such as the ÉcoPerformance program.

Hydro‑Québec’s business customers that already use electric heating and a fuel other than natural gas in dual‑energy mode for heating may be eligible for Hydro‑Québec’s new Small- and Medium‑Power Dual‑Energy Rate for Space Heating.

Does a special electricity rate apply to customers who opt for this offer?

Business and institutional customers who opt for dual energy (electricity and natural gas) benefit from Hydro‑Québec's new Small- and Medium‑Power Dual‑Energy Rate for Space Heating.

Will this solution cost more than heating exclusively with natural gas?

The offer is designed as an incentive to convert heating systems to dual energy. Financial assistance to purchase and install the equipment is provided under a partnership between the Québec government, Énergir and Hydro‑Québec. The Small- and Medium‑Power Dual‑Energy Rate for Space Heating only applies to the electricity used for space heating. The rate will enable businesses and institutions to achieve recurring savings of approximately 15% on their total energy bill.

Why are you rolling out this offer?

To help reduce greenhouse gas (GHG) emissions, since heating buildings is a major source of emissions that directly impact climate change. By joining forces, Hydro‑Québec and Énergir aim to decrease the amount of natural gas consumed by participating customers by more than 70%, thereby helping Québec reach its GHG emissions reduction target set in the 2030 Plan for a Green Economy. Under the Plan, Québec aims to cut its emissions by 37.5% by 2030 compared with 1990 levels.

Why not offer a solution to convert to an all‑electric heating system?

Heating buildings using only electricity would put significant pressure on Hydro‑Québec’s grid during winter peak periods.

Dual energy is an excellent way to maximize the use of electricity in building heating while limiting the impact on the grid during peak periods. Lowering the demand for electricity at these specific times makes it possible to optimize operations at the very moments when the grid is subject to the most pressure. This in turn will help Hydro‑Québec avoid having to make additional investments or expenditure to meet peak demand.

Between 2022 and 2030, the dual‑energy offer will save Québec nearly $1.7 billion compared to an all‑electric scenario, which would have a much greater impact on electricity rates.
