Sembcorp Tengeh Floating Solar Farm

Facing soaring energy demands, Singapore is out to quadruple solar power production by 2025. But with heavy cloud cover and just 726 square kilometers (280 square miles) of land, the tiny country has limited options. So the space-starved city-state is getting creative: introducing a 45-hectare (111-acre) floating solar farm that will power its water treatment system—making Singapore one of the few nations in the world with the capability. A partnership between Sembcorp Floating Solar Singapore and the country’s Public Utilities Board, the 60-megawatt farm could help reduce Singapore’s carbon emissions by about 32 kilotonnes annually, comparable to taking 7,000 cars off the roads.
