### English
* **Project Overview**: Tenaga Nasional Berhad (TNB) has officially commissioned the 100MW/400MWh Santong Battery Energy Storage System (BESS) in Dungun, Terengganu.
* **Strategic Function**: As Malaysia's first grid-forming "smart energy bank," the facility balances electricity supply and demand in real-time, specifically addressing the intermittency of renewable energy sources like solar.
* **Performance & Capacity**: The system supports approximately 40,000 households and can provide up to four hours of backup electricity during outages.
* **Technical Specifications**: The project utilizes advanced liquid-cooling technology and grid-forming inverters to enhance national grid stability and reliability.
* **Efficiency & Timeline**: Development was completed in just 309 days, with an estimated project lifespan of 15 years and a total investment of RM380 million.
* **Policy Alignment**: This initiative supports the National Energy Transition Roadmap (NETR), which aims for 70% renewable energy installed capacity by 2050.
