KETEP 세계에너지시장정보

Singapore, February 2, 2023 – Sembcorp Industries (Sembcorp) and the Energy Market Authority (EMA) today officially opened the Sembcorp Energy Storage System (ESS). The Sembcorp ESS is Southeast Asia’s largest ESS and spans across two hectares of land in the Banyan and Sakra region on Jurong Island. Commissioned in six months[1], the facility started operations in December 2022 and is the fastest in the world of its size to be deployed[2].
The utility-scale ESS has a maximum storage capacity of 285 megawatt hour (MWh), and can meet the electricity needs of around 24,000 four-room HDB households[3] for one day, in a single discharge. 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. It can also provide reserves to the power grid, which frees up power generation plants to generate more electricity to meet demand, when needed.
