This endeavour not only supports Singapore’s ambitious decarbonisation goals but also demonstrates how innovation and sustainability can drive impactful results. The Pulau Ubin Green Microgrid project underscores EDP Renewables' dedication to advancing clean energy solutions while upholding environmental stewardship and profitability.

Impact and innovation

The Pulau Ubin Green Micro-grid project excels in its dual focus on innovation and sustainability. The Solar Green Roof, featuring a 328kWp solar photovoltaic system, is enhanced by greenery planted beneath the panels to regulate ambient temperatures, boosting efficiency by up to 4%. Additionally, the project introduces Singapore’s first utility-scale Vanadium Redox Flow Battery Energy Storage System. This cutting-edge technology, with a lifespan of up to 25 years, offers significant advantages over traditional lithium-ion batteries, such as reduced fire risks and enhanced long-term sustainability, which makes it most suitable for remote and off-grid environments such as Pulau Ubin.

By diminishing the island’s reliance on diesel, the project has provided Pulau Ubin’s residents with a stable, clean energy source, fostering a more resilient community. It also serves as a pioneering model for future green energy solutions on off-grid islands across the Asia Pacific, where similar micro-grid systems could aid in decarbonising other island communities.

Future outlook

Looking ahead, EDP Renewables APAC is exploring opportunities with the Energy Market Authority to extend the green microgrid system beyond Pulau Ubin’s main village, potentially covering the entire island. This expansion would further integrate renewable energy into the local micro-grid, bolstering energy security and advancing Singapore’s sustainability objectives. The success of this project highlights the potential for scaling similar innovations across the region, accelerating the energy transition in Asia Pacific.
