Sembcorp Floating Solar Singapore and National Water Agency PUB have officially opened the Sembcorp Tengeh Floating Solar Farm at the Tengeh Reservoir. With 122,000 solar panels spanning across 45 hectares, the 60 megawatt-peak solar photovoltaic farm is one of the world’s largest inland floating solar PV systems. The commencement of the solar farm’s operations marks a significant step towards enduring energy sustainability in water treatment, making Singapore one of the few countries in the world to have a 100% green waterworks system while contributing to the national goal of quadrupling solar energy deployment by 2025.The electricity generated from the solar farm will be sufficient to power Singapore’s five local water treatment plants, offsetting about 7% of PUB’s annual energy needs and reducing PUB’s carbon footprint. This is equivalent to powering about 16,000 four-room HDB flats and reducing carbon emissions by about 32 kilotonnes annually, the same as taking 7,000 cars off the roads.Floats deployed are made using high-density polyethylene, a certified food-grade material that is recyclable, UV-resistant and corrosion resistant. In addition to having a comprehensive environmental management and mitigation plan, PUB and Sembcorp will continue to monitor the reservoir closely, and take necessary measures to maintain biodiversity and water quality.
