A large floating solar farm is planned for Lower Seletar Reservoir, where it will cover approximately 36% of the water surface and generate at least 130 megawatt-peak (MWp) of electricity when completed in 2029. Construction is expected to begin in 2027.
According to Singapore’s national water agency PUB, the project will contribute 6.5% of the country’s 2 GWp solar capacity target by 2030. An environmental impact assessment was conducted due to the reservoir’s role as a wildlife movement corridor linking the Central Catchment Nature Reserve to northern coastal habitats.
The assessment recommends adjusting the solar panel layout to minimise ecological impact, including buffer zones of up to 150 metres from shorelines, reorientation of panels away from sensitive areas, and breaking the installation into smaller floating “islands” with access corridors. Surveys identified over 200 animal species in the area, including several of conservation concern.
The report concludes that overall impacts on water quality and temperature are expected to be minor, while floating solar offers key benefits such as efficient land use and improved panel performance through water cooling.
