## English

* **Milestone project**: Sungrow has successfully commissioned the 100 MW/400 MWh Santong Battery Energy Storage System (BESS) in Terengganu — Malaysia's first grid-forming, grid-connected battery energy storage project
* **Owner and developer**: The project is owned and developed by Tenaga Nasional Berhad (TNB), designed to enhance grid resilience and support increasing renewable energy integration into Malaysia's national electricity network
* **Technology deployed**: Sungrow supplied 90 units of its PowerTitan 2.0 liquid-cooled energy storage systems, along with its Facility Energy Management System (FEMS) for intelligent energy dispatch and flexible grid support
* **Round-trip efficiency**: The Santong BESS achieves a round-trip efficiency (RTE) of 88% during its first year of operation, supporting both grid-following and grid-forming operating modes
* **Advanced grid capabilities**: The system features Fast Frequency Response (FFR), rapid active power ramping, voltage and reactive power control, and station-level black start capability — enabling grid restoration following a complete power outage without external voltage or frequency reference
* **Household impact**: TNB Chairman Tan Sri Abdul Razak Abdul Majid stated the BESS enhances grid reliability while supporting electricity demand equivalent to approximately 40,000 households across Malaysia's East Coast
* **Record delivery**: The project set a new record for the fastest BESS delivery in Malaysia and successfully completed a 100 MW full-power discharge test, with support from Sungrow's local service and R&D teams
* **Government recognition**: The project received recognition from Malaysia's Energy Minister and Deputy Prime Minister for its contribution to the country's energy transition
