Sungrow has commissioned the 100 MW/400 MWh Santong Battery Energy Storage System (BESS) in Terengganu, Malaysia, marking the country’s first grid-connected, grid-forming battery energy storage project.
Owned and developed by Tenaga Nasional Berhad (TNB), the Santong BESS is designed to strengthen Malaysia’s national electricity grid, improve system resilience and support greater integration of renewable energy. The project is designed to achieve a round-trip efficiency (RTE) of 88 per cent in its first year of operation and supports both grid-following and grid-forming operating modes.
The project set a record as the fastest BESS deployment in Malaysia and successfully completed a 100 MW full-power discharge test.
