One of the largest floating photovoltaic farms in the world was recently opened at Tengeh Reservoir in Singapore. The Sembcorp Tengeh Floating Solar Farm" consists of 122,000 solar panels occupying an area of 45 hectares..

The solar panels have an installed power of 60 megawatt peak (MWp), and the electricity generated will be enough to power the five local water treatment plants, offsetting 7% of PUB's annual energy needs. This facility, according to the "Greensavers" portal, will reduce about 32,000 tons of carbon dioxide (CO2) emissions annually, the same as removing 7,000 cars from the country's roads.

The Sembcorp Tengeh Floating Solar Farm" is the result of a project between Sembcorp Industries and PUB - Singapore's National Water Agency, with construction starting in August 2020. According to PUB, an Environmental Management and Mitigation Plan (EMMP) was prepared in order to minimize any impacts on the reservoir's biodiversity and water quality. "The EMMP includes monitoring and management of biodiversity, water quality, sediment quality and noise pollution before, during and after project construction," they assure.

This solar farm will allow, according to the Agency, Singapore "to be one of the few countries in the world to integrate green technology into water treatment, creating a totally green water system."
