Energy Centre

The Park is powered by two cutting-edge energy centres – one in King’s Yard on the west of the Park, and one near Westfield Stratford City forming a decentralised energy network of heating, cooling and power.

This is the largest decentralised energy scheme to be built in the UK and makes a key contribution to the Park meeting its zero carbon ambitions.

At the same time, their eye-catching design means they are new landmarks on the Park’s skyline. Both energy centres were recognised for their outstanding design by the Royal Institute of British Architects, winning regional awards in 2013.

  • 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 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 to run using different types of fuel to enable the network to make use of advances in energy technology and further reduce carbon emissions.
