Singapore’s first floating solar system
Sembcorp Solar is appointed by Singapore’s water agency PUB to build a 60 megawatt-peak (MWp) floating solar photovoltaic (PV) system on Tengeh Reservoir. Officially launched on 14 July, 2021, it has 122,000 solar panels spanning across 45 hectares (equivalent to about 45 football fields) and is one of the world’s largest inland floating solar PV systems.
Supporting the nation’s move towards the solar target of providing at least 2 gigawatt-peak (GWp) by 2030, this project will meet 7 percent of PUB’s total energy needs. We proposed the use of highly efficient PV modules and optimised layout to maximise energy generation within the specified area. 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.
