Sembcorp Industries has completed works on a 285 MWh energy storage system (ESS) facility on Jurong Island, making it the largest such facility in the Southeast Asia region. The ESS is capable of storing and delivering around 200MW of electricity per hour, enough to power 17,000 homes in a single discharge.
In June 2022, the Energy Market Authority (EMA) appointed Sembcorp to construct the facility. The ESS technology will improve grid reliability by addressing solar intermittency on overcast and rainy days.
