en.Wedoany.com Reported - Sungrow has commissioned the 100 MW/400 MWh Sungai Udang energy storage station in Terengganu, Malaysia, marking the country's first grid-forming energy storage project capable of grid-connected operation. This project lays a critical foundation for upgrading the local power grid and enabling large-scale integration of renewable energy. Fully owned and developed by Tenaga Nasional Berhad (TNB), Malaysia's national power utility, the station's core role is to enhance grid disturbance resilience, stabilize power system operation, and accommodate the country's growing demand for renewable energy grid integration.
Sungrow provided a complete integrated energy storage solution for the project, including 90 sets of PowerTitan 2.0 liquid-cooled energy storage systems, paired with a plant-level energy management system (FEMS) for intelligent dispatch and flexible grid support. In its first year of operation, the Sungai Udang energy storage station is expected to achieve a comprehensive charge-discharge efficiency of 88%, while supporting both grid-following and grid-forming operation modes to comprehensively enhance grid stability.
The storage equipment is equipped with multiple advanced grid support functions, including fast frequency response, rapid active power regulation, and voltage and reactive power control. Leveraging its grid-forming capability, it can autonomously stabilize grid voltage and frequency. The station also features full black-start capability, enabling it to restore grid power supply without an external power reference after a complete blackout.
Sungrow stated that, leveraging the coordinated efforts of its local service, project delivery, and R&D teams, the project adopted an accelerated delivery plan throughout the process. During project implementation, Sungrow helped establish local grid-forming energy storage industry standards in Malaysia. The project achieved one of the fastest grid connection speeds among Malaysian energy storage projects, set a record for the fastest delivery of a local energy storage project, and successfully passed a 100 MW full-power discharge test. Malaysia's Minister of Energy and Deputy Prime Minister both acknowledged the project's value in supporting the country's energy transition.
TNB Chairman Tan Sri Abdul Razak Abdul Majid commented that the Sungai Udang energy storage station is a landmark project for upgrading Malaysia's power system and accelerating the integration of renewable energy into the grid. The millisecond-level fast response characteristics of the energy storage system can significantly improve power supply reliability, covering the electricity load of approximately 40,000 households on Malaysia's east coast.
The official commissioning of the Sungai Udang energy storage station further advances the modernization of Malaysia's power infrastructure. The country is actively deploying large-scale centralized energy storage projects to drive its clean energy transition goals.
