As proof of London 2012's commitment to use renewable and energy-efficient technology, a state-of-the-art Energy Centre will provide power, heating and cooling across the whole Olympic Park for the entire duration of the Games - and beyond. Located in the west of the Park below the Handball Arena, the innovative Energy Centre has a biomass boiled that uses woodchip as fuel to generate heat, and a natural gas powered Combined Cooling, Heat and Power plant (CCHP). The environmental and economic benefits include a huge reduction of carbon emissions - while the design of the Centre is both flexible and sustainable to allow it to be adapted as technology progresses. After the Games, the Centre will continue to support the permanent Olympic venues as well as the new buildings and communities that will develop after 2012. A second Energy Centre has been built in the Stratford City development to provide power, heat and cooling for the on-going project, set for completion in 2020.
