Landfill Gas to Energy

The building has been constructed, the five engines have arrived the commissioning of the gas-to-energy plant took place this spring and the plant is now fully operational.


Covered mostly by a landscaped berm, the facility is located at the southeast corner of the waste site, near the intersection of Carp Road and Highway 417. The engines will be powered by gas from the existing landfill site and in turn will generate approximately 6.4 megawatts of electricity into the Ottawa grid. This amount of electricity will allow hydro to service approximately 6,400 homes a year.

What is the Landfill Gas-to-Energy Process?

  • The cycle begins with the collection of residential and commercial waste. The waste is then transported to the Waste Management, Ottawa Waste Facility for permanent disposal. A significant amount of this waste is organic in nature. Anaerobic bacteria digest this organic waste and produce methane gas and carbon dioxide as natural by-products (landfill gas).
  • The landfill gas is recovered by the gas collection system already installed at the landfill. These gas wells are connected by a pipe system that collects the gas and transports it to a nearby compression facility.
  • At the compression facility, the landfill gas is de-watered, filtered and pressurized.
  • The gas is piped to an electricity generating plant where it is used as fuel to power engines to generate electricity.
  • To complete the cycle, the electricity is delivered via utility transmission lines to residential and commercial customers.
