An electrical natural gas fired cogeneration unit that will provide substantial savings will be installed at the 317-room Rydges Sydney Airport Hotel now under construction.
Designed and installed by Simons Green Energy, the cogeneration plant is made up of a 70kW reciprocating gas engine and hot water storage tanks. The installation of the cogeneration unit will reduce the hotel’s energy costs significantly and its energy usage by 360,000 kWh a year, Simons claims.
It will provide a portion of the hotel’s electricity demands and utilise waste heat to provide hot water for the hotel’s domestic and kitchen requirements. The cogeneration system will be cleaner than coal-fired grid supplied electricity while reducing the carbon emissions by 191 tonnes a year.
Project manager Denwol Group director Phillip Wolanski said, “We wanted any green initiatives to be practical, have strong environmental outcomes and provide us with financial payback over time. The cogeneration unit provides us with these three criteria.”
Simons chief executive officer Derek Simons said the cogeneration system would be a great platform for other hotels to follow. “The system is technologically advanced and very efficient at about 85% conversion efficiency compared with 30% efficiency for conventional grid-supplied electricity,” he said.
Rydges Hotels and Resorts will manage the hotel which is due to open in mid next year
