On 10 November in Hanoi, VinEnergo Energy JSC, the green energy company of Vingroup, announced that its 5 MWh battery energy storage system (BESS) has earned UL 9540 safety certification from UL Solutions, the US safety testing and certification organisation. According to VinEnergo, it is the first BESS manufactured in Southeast Asia to achieve this certification.
A safety standard for international markets
The system is made at the VinES Ha Tinh storage battery plant and uses liquid-cooled active thermal management and an integrated active fire-protection system. To obtain UL 9540, the product underwent UL 9540A testing. It also holds UL 1973, IEC 62619 and IEC 63056 certifications, plus test reports under IEC 62933-5-2, NFPA 68 and NFPA 69.
These certifications are an important requirement for entering VinEnergo's target markets of North America, Europe and Asia, which impose strict safety rules on energy storage equipment.
A domestic deployment base
VinEnergo said it has supplied and deployed more than 1.6 GWh of BESS for EVN's power corporations as well as customers such as Marubeni, MM Mega Market and Nghi Son 2 Power. Recently, it commissioned a 45 MWh BESS combined with solar power at the Vung Ang Industrial Zone in Ha Tinh.
Energy storage is a key link that helps power systems integrate renewable sources. A domestically made product meeting international safety standards shows Vietnamese energy manufacturing gradually moving into higher-value segments.
