Heathrow Energy Centre

Responsible Heathrow case study

Heathrow’s new Terminal 2 is playing a big part in achieving our vision of making every journey better. It has been designed with the needs of passengers at its heart and with sustainability as a guiding principle.

Once open, T2 will be capable of dealing with 20 million passengers per year and the new Heathrow Energy Centre helps us to meet our energy needs cost efficiently while improving our energy efficiency by 40% more than required through building regulations  (Part L 2006).

Heathrow’s Energy Centre delivers heat and cooling to the new T2, as well as to T5, through a 10MW biomass Combined Heat and Power Plant.  It is one of the largest biomass initiatives of its kind in the UK.

The Energy Centre is helping us work towards our target to achieve a 34% reduction in CO2 emissions from energy use in our buildings by 2020 (from a 1990 baseline in line with Government CO2 targets).  When operating at its full potential, it will offset around 40,000MWh/year of gas and 12,000MWh/year of electricity, saving around 13,000 tonnes of CO2/year compared to the use of gas and grid electricity.  That’s equivalent to the annual emissions of 6,500 passenger cars.

Requiring  nearly 25,000 tonnes of woodchip per year,  ensuring the timber for the biomass boiler is sourced locally is also helping us support our local communities and further reduce CO2 emissions.. We have set a target to source 75% of the timber from within a 50 mile radius, and100% from within a 100 miles, reducing haulage requirements, costs and associated CO2 emissions from transport.   Other benefits include;

  • tightly controlled air quality emissions;
  • 100% of the ash residue can be collected and reused as soil conditioner in agriculture or forestry;
  • promoting local woodland management;
  • promoting local economic investment and employment opportunities.
