The workshop was held in a hybrid format, combining in-person and online participation. EVN Vice President Nguyen Tai Anh chaired the workshop at EVN Headquarters in Hanoi. Participants included representatives from EVN's specialized departments, the Northern Power Corporation (EVNNPC), Hanoi Power Corporation (EVNHANOI), Power Project Management Board 2, and four power engineering consulting companies under EVN.

The workshop featured experts including Mr. Kolin Low, Senior Director of Regional Standards at ULSE; Mr. Victor Ho, Vice President of the Institution of Fire Engineers, Singapore (IFE Singapore); and Mr. Winter Ho, an engineer from UL Solutions in Taiwan.

Delegates attend workshop on safety standards for battery energy storage systems (BESS) at EVN Headquarters on afternoon of November 12.

Discussions focused on UL 9540A and other safety standards relevant to battery energy storage systems (BESS). In particular, UL 9540A specifies a test method for evaluating thermal runaway fire propagation in BESS. Test data can be used to assess appropriate separation distances between systems and fire and explosion protection measures during installation.

Through the workshop, EVN's member units gained updated technical knowledge and insights into international practices to support their research, evaluation, and selection of appropriate safety standards for their BESS projects. The workshop also followed up on a meeting held on September 9, 2026, during which EVN requested ULSE to arrange for experts to share their expertise on BESS safety standards.

UL Standards & Engagement (ULSE) is one of the three organizations within UL. It is a nonprofit organization dedicated to developing and promoting the adoption of safety standards, including UL 9540A, which establishes a test method for evaluating fire propagation in battery energy storage systems.
