The Singapore’s National Environment Agency (NEA) has selected a consortium between environmental solutions company Hyflux and Japanese company Mitsubishi Heavy Industries (MHI) as the preferred bidder to S$750m ($532.3m) build waste-to-energy (WTE) plant in Tuas.

The consortium will launch a concession company to provide waste-to-energy services with Hyflux having 75% stake and MHI owning the remaining stake.

Planned to be built on a 4.8ha site near the Tuaspring integrated water and power project, the facility is expected to be the largest and most energy-efficient project of its kind in the country, upon completion in 2019.

The consortium has placed bids for the project at first-year cost of S$55.19 per ton with an option for 25-year waste-to-energy services from 2019 to 2044.

There were six bidders who offered bids for the development of the project.

The plant will complement the existing waste-to-energy plants in the country to meet increasing waste disposal needs.

NEA CEO Ronnie Tay said: "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."

Hyflux will provide engineering, procurement and construction services worth S$636m ($451m) while MHI will be responsible for providing the technology for the project, which will be jointly managed, operated and maintained by the firms.

The project is designed to produce 2,880MWh of electricity per day and will have incineration capacity of 3,600t per day (t/d).

Power generated by the facility will be used to power the plant while the excess power will meet power demands in the region.
