Hong Kong’s first combined heat and power (CHP) generation project installed in a hospital wins two more industrial awards, namely:
- Bronze Award at 2019 Hong Kong Green Innovations Awards, from the Environmental Campaign Committee alongside the Environmental Protection Department of the Hong Kong Government , in recognition of its innovative, green ideas for reducing emissions and saving energy costs.
- “5th Year Best Project Award”, organised by the Institution of Mechanical Engineers Hong Kong Branch in recognition that the CHP system has achieved an excellent total energy utilisation of 87%.
Installed at the Alice Ho Miu Ling Nethersole Hospital in Tai Po, New Territories, the CHP electricity generation project was jointly developed by the Hospital Authority and the Hong Kong & China Gas Company. As the first project of its kind in Hong Kong, the project uses landfill gas from the North East New Territories (NENT) landfill as the fuel to generate electricity as well as steam and hot water for various hospital systems and facilities. The Hong Kong & China Gas Company constructed a 19 km, 400mm diameter pipeline from NENT landfill site with a 600-metre branch pipeline to supply methane the CHP plant.
The CHP plant produces electricity and generates waste heat at a temperature of 500oC from the generator's exhaust which goes to a waste heat boiler to produce steam. Waste heat from generator cooling system is also used to heat up the hospital’s potable and non-potable hot water supply system.
WSP was the project consultant providing technical and contractual advisory services, participating the testing and commissioning acceptance tests, preparation of the standard for the overall system measurement and verification. Construction started in August 2015 and was completed in November 2016.
