The largest energy storage system (ESS) in the Southeast Asia region is now online on Jurong Island in Singapore. The 285 MWh Sembcorp ESS facility comprises 800 large-scale battery units that will store excess solar energy generated during the day. This will then used during periods of high electricity demand.
The 2-hectare site was developed by Sembcorp Industries under a contract with the Energy Market Authority (EMA). With operations commencing on the ESS facility, the Government of Singapore has achieved its 200 MWh energy storage target three years early. It is now aiming to have 2GWp of solar capacity by 2030, accounting for 3 per cent of projected electricity demand.
