Singapore's National Environment Agency (NEA) has selected a team comprising Hyflux and Mitsubishi Heavy Industries to develop Singapore's largest waste-to-energy (WTE) plant in Tuas.
The winning consortium will form a concession company to enter into a Waste-to Energy Services Agreement (WESA) with NEA to provide 3,600 tonnes per day (t/d) of incineration capacity. Hyflux will undertake engineering, procurement and construction (EPC) works worth S$636 million (US$455 million), while Mitsubishi Heavy Industries will provide the technology.
The tender process attracted six bids from both local and international companies. At a first-year cost of S$55.19 per tonne, the winning team submitted the most competitive offer for the development of a WTE plant and the provision of waste-to-energy services over a 25-year period from 2019 to 2044.
The project, situated on a 4.8 hectare site next to Tuaspring Integrated Water and Power Project, will be Singapore's largest and most energy-efficient WTE plant. It will be able to produce 2,880 MWh of electricity daily, which is equivalent to 800kWh per tonne of waste incinerated under standard operating conditions. The electricity will be used to power the plant and the excess power will go towards supplying Singapore's needs.
The total project investment is estimated at S$750 million (US$536 million).
NEA's Chief Executive Officer, Mr Ronnie Tay, stated:
"The new Waste-to-Energy plant is part of NEA's long-term plan to meet Singapore's future waste management needs. With the scarcity of land in Singapore, the constant challenge is to find the most efficient solutions. This plant will be developed to optimise land use, achieve greater environmental sustainability and further provide for Singapore's waste management needs."
