Fire at Zhuyuan Extra High Voltage substation in Hsinchu kills two workers

A fire broke out at the Zhuyuan Extra High Voltage Substation in Hsinchu City, Taiwan, on a Monday in March 2026 during equipment testing. Three workers at the site were injured and taken to hospital. Two of them later died from their injuries, raising the death toll to two. Taiwan Power Co., which operates the facility, confirmed the incident. Prosecutors, fire investigators and police jointly carried out evidence collection at the site the following day. Firefighting operations were completed and crews withdrew, with the site handed over to fire investigators for further examination. The case remains under investigation, with authorities stating that further details will be released once findings are confirmed.

The fire occurred during equipment testing at the substation, though the specific technical cause had not been confirmed at the time of reporting.

1. Equipment testing at high voltage substations carries elevated risk and should be conducted with strict safety protocols and exclusion zones for personnel not directly required.
2. Multi-agency investigation involving prosecutors, fire investigators and police can help establish root cause in fatal grid infrastructure incidents.
3. Operators should ensure rapid medical response capability is in place during planned testing activities at high voltage facilities.
