Energy Centre

This energy centre is one of two situated around the Park. The other is next to Stratford station. Together, they supply electricity and hot & chilled water (for air conditioning) to sporting venues, to Westfield and to housing in and around the Park.They form the largest decentralised energy scheme in the UK.


The energy centres have been designed to work using combined heat and power (CHP) engines, which generate electricity and produce hot water. The hot water is distributed throughout the Park by a network of pipes providing heat to venues, commercial buildings and residential properties.


Chilled water is also produced by passing the hot water through an absorption chiller. This is then distributed by pipes to provide air-conditioning in some of the Park’s buildings.


This is more efficient, and produces fewer carbon emissions, than taking power from the national grid (where the heat generated by power stations is typically lost to the air) or each building generating their own heat and cooling by having an individual boiler or air-conditioning unit. This will provide homes on the Park with affordable heat.


Developments around the Park are also able to connect their buildings to the network provided by these centres and benefit from this efficient energy.


Each energy centre has been designed, financed and built by, the energy services company Engie, along with approximately 18km of insulated heat and cooling networks as part of an energy concession on the Park. The concession will be operated by Engie for 40 years.


Each centre:

  • Has an initial capacity of 46.5 MW of heating and 16 MW of cooling, with space for additional boilers and engines to increase this capacity in the future
  • Is 45m tall at its highest point
  • Includes five cooling towers, and two hot water storage tanks each weighing around 60 tons
  • Uses zero carbon renewable energy sources such as biomass or bio-fuel
  • Has been designed to be able run using different types of fuel to enable the network to make use of advances in energy technology and further reduce carbon emissions.
