SINGAPORE: The largest energy storage system in Southeast Asia opened on Jurong Island on Thursday (Feb 2), in another push for solar power adoption in Singapore.
The Sembcorp Energy Storage System has a maximum storage capacity of 285 megawatt-hours (MWh), enabling it to meet the electricity needs of about 24,000 households in four-room flats for one day in a single discharge.
The facility spans 2ha – the size of nearly three football fields – and started operations last December. The Energy Market Authority (EMA) appointed Sembcorp Industries to develop it in June 2022.
“Its rapid response time to store and supply power in milliseconds is essential in mitigating solar intermittency caused by changing weather conditions in Singapore’s tropical climate,” Sembcorp and EMA said in a joint media release.
“It can also provide reserves to the power grid, which frees up power generation plants to generate more electricity to meet demand, when needed.”
EMA chief executive Ngiam Shih Chun said the energy storage system will complement the authority’s efforts to maximise solar adoption, as well as enhance the power grid’s stability and resilience.
The deployment of the utility-scale facility means that Singapore has achieved its 200 MWh energy storage target ahead of time, he noted.
Singapore previously announced a target of deploying at least 200 MWh of energy storage systems beyond 2025 as part of the Singapore Green Plan 2030.
