4 March 2010 – Australia’s Qantas Airways and GridX Power have signed an agreement to build the first significantly-sized trigeneration plant in New South Wales.
The proposed 9.6 MW plant, to be fuelled with natural gas, will provide electricity, chilled water and hot water to Qantas at Sydney Airport Domestic Terminal 3, Qantas Jetbase and the Qantas catering facility.
Emissions of carbon dioxide from Qantas’ operations associated with its use of electricity will be reduced by around 50%, says GridX, and the trigeneration plant will also relieve pressure on the main electricity grid at times of peak and shoulder use.
Site works are due to commence at Sydney Airport in September, under a 15-year build, own, operate and maintain arrangement with GridX, and the scheduled completion date is July 2011,.
Qantas says that the plant will be the first to be undertaken by an Australian airline. The company’s Chief Risk Officer, Rob Kella, said that trigeneration power, ‘will increase the security and reliability of our electricity supply and enable further maintenance and operational savings.’
By capturing heat that would otherwise be lost, trigeneration can achieve energy efficiencies of around 80%, compared with an average of 35% for a conventional supply of energy from the grid.
