Heathrow Energy Centre

Responsible Heathrow case study

We use local renewable woodchips to heat T2

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.

Opened in June 2014, T2 welcomes 20 million passengers per year. The new Heathrow Energy Centre provides 20% renewable energy to T2, helping 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 T2 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 used 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 each year compared to the use of gas and grid electricity. That’s equivalent to the annual emissions of 6,500 passenger cars.

The biomass boiler needs around 25,000 tonnes of woodchip per year. We source the timber locally (75% from within 50 miles) which helps support our local communities through providing jobs and further reducing CO2 emissions from transport. Other benefits include:

  • Tightly controlled air quality emissions;
  • 100% of the bottom ash is collected and reused as a soil conditioner in agriculture or forestry;
  • Promoting local woodland management;
  • Promoting local economic investment and employment opportunities.

Responsible Heathrow 2020 is our commitment to supporting the UK and local economies and reducing Heathrow’s environmental impacts, while looking after our people and passengers.It is helping us achieve our ambition to be one of the most responsible airports in the world.
