Battery energy storage systems (ESS) provide critical frequency and stability support to power grids. As one of Asia’s largest battery operators, our energy storage portfolio is well-positioned to support the evolving needs of power markets as they increase their uptake of renewable energy.

The Sembcorp Energy Storage System is Southeast Asia’s largest utility-scale ESS of 285MWh. Built across two sites on Jurong Island, our ESS enhances Singapore’s grid resilience by mitigating the impact of solar intermittency as the republic progresses towards achieving its 2030 solar target of at least 2GWp and energy storage systems deployment of 200MWh beyond 2025.

Capable of actively managing mismatches between electricity supply and demand, our ESS can provide power to meet the daily electricity needs of around 24,000 four-room public housing flats in a single discharge.
