TuasOne - The Latest And Most Land Efficient Waste-To-Energy Plant In Singapore

27 Jul 2022

Singapore’s sixth waste-to-energy (WTE) plant can incinerate 3,600 tonnes of waste and generate 120 megawatts of electricity daily. The electricity produced is sufficient to power about 240,000 HDB flats.

Singapore, 27 July 2022 – The TuasOne Waste-To-Energy Plant (TuasOne) was developed under the Public-Private-Partnership framework to provide waste incineration services to the National Environment Agency (NEA). This is Singapore’s sixth WTE plant and the second that was developed under a Design, Build, Own and Operate model[1]. The plant commenced initial operations in December 2021 and has steadily increased its operating capacity since.  

2          TuasOne has appointed Mitsubishi Heavy Industries Environmental & Chemical Engineering ECO Creation Singapore Co. Ltd (MHIEC ECO Creation) as its long-term operations and maintenance contractor on 22 July 2022. Prior to the appointment of MHIEC ECO Creation, Mitsubishi Heavy Industries Asia-Pacific Pte. Ltd. (MHIAP) had been operating the plant.

Key highlights of TuasOne

3          Some of the key features of TuasOne are:

a. The plant can incinerate 3,600 tonnes of waste and generate 120 megawatts (MW) of electricity daily;

b. It is located on 4.8 hectares of land and is the most land efficient WTE plant in Singapore to-date;

c. The plant is designed for higher heat recovery from waste incineration and higher electrical power generation efficiency.

4          TuasOne will provide waste incineration services for a minimum period of 25 years to help Singapore meet its long-term waste management needs while recovering energy from waste. The energy generated from incineration is enough to meet the electricity demand of 240,000 4-room HDB flats. Incineration also helps to reduce the volume of waste to ash, by up to 90 per cent (refer to Annex A for photos of TuasOne). With the commencement of operations at TuasOne which was developed to replace the Tuas Incineration Plant (TIP) while catering for growth in Singapore’s WTE capacity, NEA has decommissioned the Tuas Incineration Plant (TIP) after its 36 years of service (refer to Annex B for more information on the decommissioning of TIP).

ANNEX B

Decommissioning of Tuas Incineration Plant (TIP)

Tuas Incineration Plant (TIP) was Singapore’s second WTE plant, which was built on 6.3 hectares of reclaimed land at an estimated cost of S$200 million. TIP has treated approximately 18 million tonnes of general waste since started operations in 1986.

2          The heat recovered from the waste incineration process was used to generate approximately 6,400,000 MWh of electricity, the equivalent amount of electricity used by about 40,000 4-room HDB flats over TIP’s 36-year lifespan.

3          Although TIP has been decommissioned, NEA is currently exploring the possibility to repurposing parts of its infrastructure for other waste management activities.

4          Below are quotes from past General Managers of TIP who have shared their memories and experiences working at the plant:

With the decommissioning of TIP, I fondly remember the years from 1986 to 1995 when I started my career as a young engineer. I remember that TIP was sited on a piece of reclaimed land near the sea and was rather inaccessible as it took me more than an hour to report to work by bus. Now, the Tuas area is well developed and accessible by MRT. It was at TIP that I had the opportunity to learn and gain valuable skills and knowledge with the guidance of the experienced pioneers who willingly shared what they knew about the operations and maintenance of the incineration plant. In 2014, I was posted back as GM and served till 2018. Many of the pioneers have since moved to other WTEs and other positions in NEA. As the GM, I had the honour of again working with a dedicated and professional team that was committed to ensuring the safe and continuous reliable operation of an aging plant. I would like to pay a tribute and thank every officer that has served during the 36 years of TIP’s service life”

  • Pang Fook Chong, General Manager of TIP from 2014 to 2018

     

    “I am honoured and humbled to be the last GM of TIP. During my tenure, we had one common goal, which was to work together to ensure that the plant continued to operate efficiently to meet Singapore’s solid waste management needs until the day it was decommissioned. TIP has operated for a remarkable 36 years, and this would not have been possible without a group of dedicated and committed co-workers. I would like to take this opportunity to thank each and every officer in TIP for making this journey with me over the past 4 years.” 

  • Ng Wah Yong, General Manager of TIP from 2018 to 2022
