How District Energy Works

  • Twitter

District energy systems operate by producing thermal energy in the form of steam, hot water or chilled water for distribution through a network of insulated pipes.

District energy systems use one or more types of fuel and can consist of a combination of different heat sources and technologies.

 Although traditional sources of fuel - such as natural gas and oil - are most common, alternative and renewable sources (solar power, geothermal energy, biogas, biomass, heat rejected from industrial and municipal operations, and fuel-cell technologies) are now being used in plants across Canada.
