We are committed to promoting green culture through environmental awareness programmes and minimisation of wastage by focusing on the ‘3Rs’ approach to reduce, reuse and recycle materials at our corporate office and power station.

Each employee plays an active role in our waste minimisation programmes to reduce the volume of wastes generated at the corporate office and plants.

The Company tries to reuse existing resources in our operations as much as possible. For instance, the waste water from electricity generation is recovered and reused at our water treatment facilities. As a result, our water consumption (per kWh) is one of the lowest among the major electricity generating companies in Singapore. Other measures implemented include reuse of office supplies, and use of re-manufactured toner cartridges and recycled papers.

Environmental considerations form an integral part of our operations, starting from the design of the plant right down to fuel selection.

Environmental concerns were fully addressed prior to the construction of the power station. Consultants specialising in environmental protection were engaged to conduct an environmental impact study in 1993. Tuas Power Station was thus designed and constructed with environment-friendly features.

In addition, Tuas Power Station has included in its design extra features that would mitigate any environmental hazards. For instance, all chemical tank yards are surrounded by bund walls, which serve as a secondary containment. The tank yards are also connected to chemical-resistant underground tank that are equipped with neutralisation facilities. In addition, cut-off valves were installed across drains at strategic locations to contain any chemical spillage within the confined perimeter of the power station.

80 per cent of our electricity is generated by our Combined Cycle Plants, which runs on environmentally friendly natural gas, and all of our plants are equipped with high efficiency electrostatic precipitators that remove dust from flue gas generated from electricity production. Advanced fuel combustion systems including low NOx burners and the neutralisation of acid traces from the flue gas also ensure minimal emission to atmosphere. These have enabled us to keep our emissions low.

A comprehensive network of waste collection and treatment systems that spans the entire compound of the power station was installed to segregate and treat various types of wastes arising from electricity generation (e.g. oily wastes, wastewater and chemical waste).

Tuas Power Station is equipped with a full range of environmental surveillance and protection devices so our operators in the central control room are able to assess the environmental performance of our plants and respond immediately to any departure from performance norms. For instance, CCTVs are used to monitor flue stacks smoke condition and real-time emission data are collated at the central control room. Employees are also trained to look out for potential environmental concerns around the station.
