Singapore floats 122,000 solar panels on a reservoir; cuts 32,000 tonnes CO₂ yearly

Singapore has turned part of a reservoir into a giant renewable-energy installation, covering about one-third of Tengeh Reservoir with more than 122,000 floating solar panels spread across 10 floating islands. The 45-hectare Sembcorp Tengeh Floating Solar Farm has a capacity of 60 MWp and generates electricity used to support five local water-treatment plants. The project is estimated to reduce carbon emissions by about 32,000 tonnes a year, while two-thirds of the reservoir remains open. Gaps between the floating panels allow sunlight and airflow to reach the water, and additional aerators help maintain dissolved oxygen levels. The installation was preceded by years of testing and environmental studies designed to determine whether large-scale solar generation could coexist with Singapore’s water infrastructure and surrounding ecosystem.Why Singapore put solar panels on a reservoirSingapore has limited land but receives abundant sunlight, making solar power one of its most practical renewable-energy options. The country's water reservoirs offered another possible location for large-scale solar generation without requiring large areas of additional land. PUB began investigating flo...
