Sungrow has commissioned the 100 MW/400 MWh Santong battery energy storage system (BESS) in Terengganu, marking Malaysia’s first grid-forming, grid-connected utility-scale battery energy storage project. Developed and owned by Tenaga Nasional Berhad (TNB), the project is designed to enhance grid resilience, improve system stability and support the integration of renewable energy into Malaysia’s national electricity network.
Sungrow supplied 90 units of its PowerTitan 2.0 liquid-cooled energy storage system together with its Facility Energy Management System (FEMS) to enable intelligent energy dispatch and flexible grid support. The Santong BESS is designed to achieve a first-year round-trip efficiency of 88 per cent and supports both grid-following and grid-forming operating modes.
