Technical FAQs 4

What is Singapore's first utility-scale energy storage system?

Singapore’s First Utility-scale Energy Storage System Through a partnership between EMA and SP Group, Singapore deployed its first utility-scale ESS at a substation in Oct 2020. It has a capacity of 2.4 megawatts (MW)/2.4 megawatt-hour (MWh), which is equivalent to powering more than 200 four-room HDB households a day.

Why is energy storage important in Singapore?

Mr Puah Kok Keong, Chief Executive, EMA said: “As Singapore expands solar deployment, energy storage systems will become more important to enhance grid resilience and ensure power system stability. I welcome the development of energy storage systems that are safe, cost-effective and space-efficient.” -- End -- About the Energy Market Authority

Does Singapore need energy storage systems to manage solar intermittency?

However, the minister said there is a need to “step up energy storage systems to manage solar intermittency.” Talks are currently ongoing with Sembcorp, the engineering conglomerate behind the 200MW/285MWh battery energy storage system (BESS) installation on Singapore’s Jurong Island.

When will Southeast Asia's largest energy storage system be up?

The Republic will achieve its target of having “giant batteries” to store at least 200MW of energy three years early, when Southeast Asia’s largest energy storage system on Jurong Island is up and running by November.
