Since November 6, Énergir, in conjunction with Hydro-Québec and Écoperformance, has been offering its commercial and institutional dual-energy program to its commercial, institutional and multi-unit residential clients. This program, which is in addition to existing energy efficiency programs, will accelerate decarbonization of buildings by leveraging the complementarity between hydro power and natural gas. How can dual energy reduce building energy bills and greenhouse gas (GHG) emissions? And what role can renewable natural gas (RNG) play in the equation? We’ll tell you about that and more in this article.<\/h2>\n<\/div>\n<\/div><\/div>

How does dual energy work?<\/h3>\n

Dual energy involves electrifying a building’s heating system while maintaining natural gas heating. So long as the outside temperature remains above -12°C (or -15°C for customers in Abitibi and the Saguenay), the electrical system provides the heat. When the temperature falls below the threshold, the gas-powered equipment takes over to take pressure off the power grid. Depending on the type and capacity of the electrical equipment used, natural gas (and therefore GHG) savings can be as high as 70% to 80%.<\/p>\n

Fictitious decarbonization scenario in a school<\/h3>\n

To help you understand how this solution works in practice and compare the benefits under the different scenarios, let’s look at a fictitious example of decarbonizing a school.<\/p>\n<\/div>\n<\/div><\/div>

Initial situation:<\/h4>\n

High school with a 2000 MBH boiler used to heat the building via a hydronic system. The boiler uses 90,000 m3<\/sup> of natural gas annually. The boiler aside, we’re assuming that the school has already optimized its energy performance (all cost-effective measures have been subsidized by our programs).<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>
