ENGIE has completed over 380 district heating and cooling networks around the world. We have several exciting projects underway in
Australia.
How does district energy work?
District Heating
One of the most efficient way to decarbonise cities.
A district heating network is a system that produces heat from a central location using gas, renewable energy or waste heat. Underground pipes then deliver hot water or steam to the heating and hot water systems in buildings in a closed loop. The water is returned to the plant to be heated and returned again and again.
District heating networks can be fed by a diverse range of often renewable, or waste heat, sources including:
- Waste heat from power stations or industrial processes
- Energy from waste (EfW) facilities
- Biomass and biogas fueled boilers and CHP plants
- Gas-fired CHP units
- Fuel cells or solar thermal
- Heat pumps
- Geothermal sources when available
- Electric boilers (usually from wind or PV renewable electricity)
