PAKA, Malaysia, July 7, 2026 /PRNewswire/ — Sungrow, the globally leading PV inverter
and energy storage system provider, announced the official commissioning of the **
Santong Battery Energy Storage System (BESS)**, owned and developed by **Tenaga 
Nasional Berhad (TNB)**, marking another major milestone for Malaysia in advancing
battery energy storage system connected to the national grid.

Located in Terengganu, the **100MW / 400MWh Santong BESS **project plays a critical
role in Malaysia’s energy transition journey, reinforcing national grid resilience
while enabling broader renewable energy integration. Designed to meet stringent 
grid performance requirements, the project targets **88% round-trip efficiency (
RTE) **in its first year of operation and supports both **grid-following and grid-
forming operating modes** to enhance system stability and reliability.

For this landmark deployment, Sungrow delivered a fully integrated energy storage
solution comprising **90 units of PowerTitan 2.0 liquid-cooled energy storage systems(
ST5015UX-4H + MVS5140-LS)** together with the **FEMS (Facility Energy Management
System)**, enabling intelligent dispatch and flexible grid support capabilities.

At the core of the project are multiple advanced grid-support functions that strengthen
operational flexibility and enable higher renewable penetration, including:

 ◦ Fast active power ramping and Fast Frequency Response (FFR) for frequency support
   dynamic grid balancing.
 ◦ Voltage and reactive power control for voltage regulation and improved power 
   quality.
 ◦ Grid-forming capabilities, characterized by voltage-source behavior and  autonomous
   voltage/frequency support, enabling inertial response, power oscillation damping,
   on/off-grid operation, and microgrid applications.
 ◦ Station-level black start capability, enabling Sungrow’s grid-forming PCS to 
   establish a stable AC network under complete blackout conditions without an external
   voltage or frequency reference, while demonstrating coordinated multi-converter
   operation, balanced power sharing, and stable system restoration.

Delivered under an accelerated execution schedule toward commercial operation date,
the project also demonstrates Sungrow’s strong execution efficiency and collaborative
delivery capability:

 ◦ Supported by Sungrow’s local service team, headquarters project delivery team,
   and grid-forming/microgrid R&D team, ensuring efficient execution from customized
   FAT testing to commissioning and grid connection.
 ◦ Contribution to Malaysia’s early grid-forming standard framework development,
   while achieving one of the fastest BESS grid-connection timelines in the country.
 ◦ Maintained close alignment with **TNB**, the project owner, on project objectives,
   execution, and delivery throughout the project lifecycle.

The project achieved the fastest BESS delivery record in Malaysia to date and became
the country’s first grid-forming grid-connected battery energy storage system project.
Leveraging proactive local service support and end-to-end project execution, Sungrow
successfully facilitated the 100MW full-power discharge test and secured recognition
from Malaysia’s Energy Minister and Deputy Prime Minister, demonstrating its strong
service, delivery, and customer support capabilities.

_"Santong BESS marks an important milestone in strengthening Malaysia’s power system
and advancing renewable energy integration," _said **TNB Chairman Tan Sri Abdul 
Razak Abdul Majid**._ "Its rapid response capability enhances grid reliability and
supports electricity demand equivalent to approximately _**_40,000 households_**_
across the East Coast."_

As energy systems continue to evolve toward greater flexibility and decarbonization,
Sungrow remains committed to delivering innovative storage solutions that empower
utilities and grid operators to build a cleaner and more resilient energy future.
