Renewable natural gas (RNG)

Énergir is actively seeking to increase the quantities of renewable natural gas in its network to sell to its customers. RNG is a natural gas that is produced from a 100% renewable: organic wastes.

Renewable natural gas

An energy produced here

Transforming organic matter like table scraps into energy: a concrete solution in the fight against climate change. This renewable natural gas produced locally can be added to the gas network or used directly to heat buildings or as a fuel. It's one big step closer to energy independence.

Shining the spotlight on RNG producers

To meet the growing demand for renewable natural gas, Énergir deals with suppliers from all over Quebec and North America.

Saint Hyacinthe

Since January 2018, Saint-Hyacinthe has been the first city to inject biomethane into the Énergir network. Each year, more than 149,300 tons of organic waste will be transformed into 13 million m 3 of renewable natural gas. From this volume, 1 million m 3 will be used to heat municipal buildings and 12 million m 3 will be injected into the gas network to supply other cities, institutions or private customers.


Starting in 2023, the City of Québec will be injecting renewable natural gas into Énergir's network. The Quebec Agglomeration Biomethanation Center (CBAQ) is currently under construction. The plant will treat:

  • food residues (86,600 tons/year)
  • biosolids (a product of the wastewater treatment plant) (96,000 tonnes/year).

Coop Agri-Energy Warwick

Coop Agri-Énergie Warwick is the first agricultural cooperative dedicated to the production of renewable energy in Quebec. It brings together roughly ten agricultural producers from the Arthabaska RCM who will produce renewable natural gas (RNG) from slurry and manure from dairy cattle mixed with residual organic matter from surrounding businesses. The biomethanation complex will be developed, built and operated by Coop Carbone, a non-profit solidarity cooperative working on the development of cooperative agricultural biomethanization projects. The start of operations is already planned for spring 2021.

Laval University becomes the first Quebec university to buy renewable natural gas

The agreement between Laval University and Énergir for the supply of renewable natural gas (GNR) supports the University's sustainable development mission and adds to its approach to reduce energy consumption and combat climate change.
