Sembcorp opened Singapore’s first solar farm with an integrated rainwater harvesting system today.

The Sembcorp Tuas Solar Farm has a combined solar capacity of 17.6MWp and is built across two sites. Estimated to be sitting on close to 10 hectares of temporary vacant land, the solar farm is designed to be modular and flexible, using mobile solar panels, a mobile transformer and hybrid SPPG substations, which can be redeployed when the land is needed for other uses.

    • Sembcorp Tuas Solar Farm I: 16.1MWp solar energy system in Tuas Bay Lane
    • Sembcorp Tuas Solar Farm II: 1.5MWp solar energy system in Tuas West Drive

A total of 33,580 solar panels have been installed across both sites, providing renewable energy channelled to the grid. The system is expected to produce about 22,025 megawatt hours of power annually, which is enough renewable energy to power about 4,681 four-room HDB flats for a year. This will also help to avoid over 8,900 tonnes of carbon dioxide emissions a year, equivalent to planting close to 150,000 trees.

Singapore’s First Solar Farm with an Integrated Rainwater Harvesting System

The Sembcorp Tuas Solar Farm I at Tuas Bay Lane is unique and incorporates a first-of-its-kind integrated rainwater harvesting system in Singapore. In addition to the generation of solar energy, this system also collects and treats up to 170,000 cubic metres of rainwater annually, which is equivalent to the amount required to fill 68 Olympic-sized swimming pools.

Rainwater is collected via a drainage network built between the solar panel arrays and connected to an underground water storage tank that has been constructed using a geocellular system. The modular nature of geocellular systems means that they can be tailored to suit the specific requirements of any site.

The treated rainwater, which has been neutralised and free of contaminants and odour, will primarily be for non-potable use to further clean the solar panels on site, as well as for solar panel cooling purposes. Solar panels are known to yield about 2-5% higher output energy when exposed to a water-based cooling system.

Supporting Singapore’s Green Plan 2030

This project is part of Sembcorp’s focused strategy to grow its renewable energy portfolio and play its part in building a sustainable future. It also demonstrates the company’s commitment and competencies to support Singapore’s Green Plan and the nation’s solar deployment target of at least 2GWp by 2030.
