• Solar power farm to reduce carbon emissions by about 32 kilotonnes annually
• Carbon emissions reduction equivalent to taking 7,000 cars off the road
(AF) Singapore unveiled one of the world’s largest floating solar panel farms, spanning an area equivalent to 45 football fields and producing enough electricity to power the island’s five water treatment plants.
The project is part of efforts by the land-scarce city-state to meet a goal of quadrupling its solar energy production by 2025 to help tackle climate change. Located on a reservoir in western Singapore, the 60 megawatt-peak solar photovoltaic (PV) farm has been built by a wholly-owned subsidiary of Sembcorp Industries.
The solar farm could help to reduce carbon emissions by about 32 kilotonnes annually, comparable to taking 7,000 cars off the roads, according to a joint statement by the company and Singapore‘s national water agency PUB. As opposed to conventional rooftop solar panels, floating ones perform between 5% to 15% better because of the cooling effect of the water, and are not impacted by shading from other buildings, according to a presentation on the project.
The electricity generated from the 122,000 solar panels on the 45-hectare (111-acre) site should make Singapore one of the few countries in the world to have a water treatment system fully powered by sustainable energy. To allay concerns about the environmental impact of such projects, PUB said an assessment was conducted before installing the solar panels to ensure there was no significant impact on wildlife or water quality.
“It was carefully designed to improve airflow and allow sunlight passing through the water (to reach aquatic life),” said Jen Tan, a regional head at Sembcorp Industries.
The solar panels are designed to last for 25 years and drones will be used to assist with maintenance. There are four other floating solar panel projects underway in Singapore.
Meanwhile, over 144,000 solar panels are being installed on a similar project – a 45MW floating solar farm – on the Sirindhorn Dam in Ubon Ratchathani in the Northeast of Thailand.
The Electricity Generating Authority of Thailand (EGAT), the state power utility, signed a contract with B.Grimm Power Plc to build the solar farm, with photovoltaic panels worth 842 million baht ($25.77 million) on the dam, where an Egat has a hydropower plant. The solar project, which works in tandem with 36MW of hydropower generation, is due to begin operating this month.
