Singapore on Thursday officially opened the largest energy storage system in Southeast Asia as part of the city-state''s efforts to guarantee energy security amid the global energy crisis and transition toward clean energy.
The Sembcorp Energy Storage System, which started operations in December last year, has a maximum storage capacity of 285 megawatt hours. Its operator opened the completed site to the media and held a launch ceremony Thursday.
It is designed to store surplus power that can be delivered to the grid to mitigate solar intermittency caused by changing weather conditions in Singapore''s tropical climate.
The giant lithium iron phosphate batteries located in container-like structures are located on two sites spanning two hectares of land on Jurong Island, a man-made island that houses Singapore''s petrochemical complex.
Amid the global energy crisis, the government appointed Sembcorp Industries to build the facility in June last year. It is the fastest deployment in the world of an energy storage system of its size, Sembcorp Industries and the Energy Market Authority said in a statement.
Aside from enabling the scaling up of solar power, the facility "can also be used to store energy to provide reserves to the power grid," Tan See Leng, Singapore''s manpower minister, said at the ceremony. "It''s a key solution in terms of enhancing our energy security and our grid resiliency."
More than 95 percent of Singapore''s electricity supply currently comes from imported natural gas but the city state has been trying to diversify its energy mix, especially through solar.
In 2021, Singapore unveiled one of the world''s largest floating solar panel farms, spanning an area equivalent to 45 football fields. It is able to power five local water treatment plants and contribute to the national goal of quadrupling solar energy deployment by 2025.

SINGAPORE - The country''s first-ever utility-scale Energy Storage System (ESS) has been installed at a Woodlands substation, said the Energy Market Authority (EMA) on Thursday (Oct 22).
The ESS installation is part of an initiative by the EMA in collaboration with industry stakeholders, the research community and other government agencies to grow Singapore''s solar energy capacity.
The utility-scale system will manage the storage of solar energy, among other functions. Its quick response when solar installations are affected by cloud cover and rain makes it a reliable source of power.
While the system is being tested, it will participate in the wholesale electricity market to mitigate power fluctuations from solar energy, as well as reduce peak demand.
"The deployment of ESS, designed for local conditions, will enable us to incorporate a greater amount of renewables and other sustainable energy solutions into our electricity grid," said group chief executive officer of SP Group Stanley Huang.
The EMA has also worked with HDB, Sunseap Energy Ventures, Nanyang Technological University (NTU) and Panasonic Asia Pacific to deploy distributed ESS at electrical switch rooms for five HDB blocks in Punggol.
By using HDB blocks as test sites, the project looks to solve problems that might arise in future deployments due to intermittent solar energy at large-scale installations.
These energy storage systems are "critical in supporting Singapore''s target of at least 2 gigawatt-peak of solar deployment by 2030", as they help to integrate more solar energy into the power grid, said EMA chief executive Ngiam Shih Chun.
Commissioned by EMA, the road map was created by Energy Research Institute @ NTU and the Agency for Science, Technology and Research to chart the technological trends and economics of the ESS ecosystem.
Complementing the road map is the Technical Reference 77 (TR 77), Singapore''s first set of technical guidelines to educate and guide consumers on the safe and reliable deployment of ESS in Singapore.
