Energy storage systems (ESS) mitigate the intermittency of renewable energy sources such as solar and wind. They help to ensure a stable power supply by storing excess energy during high generation and discharging when needed. By responding quickly to demand fluctuations and outages, these systems enhance grid stability and reliability, providing reliable power to industries and communities.
Gross ESS capacity*
As one of Asia-Pacific’s largest battery operators, Sembcorp's expertise in energy storage systems positions us well to support the transition to a resilient and low-carbon energy system.
Singapore
In Singapore, we operate Southeast Asia’s largest energy storage system. The 326MWh system on Jurong Island supports the country's growing deployment of solar energy, while enhancing grid reliability and energy supply security.
Australia
In Australia, we are actively growing our energy storage capabilities through large-scale battery projects. Two projects are currently under construction - the Wagerup Battery and the Reeves Plains Energy Hub projects – with a combined capacity of 1.2GWh. Together, they support a more flexible and resilient power system while enabling greater integration of renewable energy.
China
In China, we constructed a 200MWh energy storage system in Hunan in under four months. The system has helped to provide critical relief to the power supply pressures in Hunan and Hengyang, promoting energy reliability and enhancing economic efficiency. Our energy storage system has also helped to pave the way for future renewable energy projects in the region.
India
In India, we made our first foray into the battery energy storage market with our first solar-energy storage hybrid project win. The 150MW solar photovoltaic project, coupled with a battery energy storage system (BESS) of 300MWh is part of a bid for inter-state transmission system-connected solar projects issued by the Solar Energy Corporation of India. Upon completion, the BESS will provide on-demand power to support daily peak electricity for four hours, over a 25-year period.
Indonesia
In Indonesia, we are expanding our energy storage capabilities through integrated renewable energy projects, including the 14.2MWh battery energy storage system in Nusantara and the 80MWh Sumber Energi Surya Morowali project, which combine solar and battery energy storage solutions to support reliable and sustainable power supply.
UK
In the UK, we have 420MWh of battery energy storage in operation and under development. When fully completed, it will be one of the UK’s largest battery energy storage facilities, as the nation advances towards its net zero target.
