Fatal fire at Taiwan substation in Hsinchu during equipment testing leaves one dead, two injured
A fatal fire at a substation in Hsinchu killed one worker and injured two during equipment testing. Authorities say the blaze did not disrupt power to the nearby science park, but investigations into safety procedures are under way.
- Fire at Hsinchu substation kills one, injures two during testing
- No major power disruption to science park despite voltage drop
- Authorities halt work and launch investigation into safety lapses
A fire broke out on 16 March 2026 at the Zhuyuan Extra High Voltage Substation in Hsinchu, killing one person and injuring two others, according to local authorities.
The Hsinchu City Fire Bureau said it received reports of a suspected explosion at 3:27 pm.
Firefighters arrived within six minutes and began efforts to contain the blaze.
The fire was brought under control at around 9:00 pm after more than five hours of continuous firefighting operations.
Three individuals were transported to hospital following the incident. One, a man in his forties, suffered severe burns and was later pronounced dead.
A 51-year-old worker sustained a closed fracture to his right thigh after being thrown by the force of the explosion.
Another, aged 56, suffered extensive burns across his body.
Authorities confirmed all three were contractor personnel working at the site during testing operations.
Cause and site conditions
According to the fire bureau, the blaze occurred at a construction area within the substation, rather than in operational facilities.
The presence of large quantities of insulating oil contributed to the prolonged burning.
Taiwan Power Company stated that the fire broke out while voltage stabilisation equipment, known as a static synchronous compensator (STATCOM), was undergoing testing.
The equipment had not yet been integrated into the active power system and remained under contractor responsibility.
Despite initial concerns, authorities confirmed that the incident did not disrupt electricity supply to the Hsinchu Science Park.
Taipower reported a brief voltage drop affecting some users, but no power outage occurred.
Taiwan Semiconductor Manufacturing Company said its operations were unaffected and that power supply remained stable.
Officials emphasised that the testing facility was housed in a separate building from operational infrastructure, preventing wider disruption.
Hsinchu Mayor Ann Kao ordered an immediate suspension of work at the site and called for a thorough investigation.
She stressed that power infrastructure is critical to both public safety and industrial operations, and instructed Taipower to clarify the cause and assign responsibility.
Authorities have also activated occupational accident support mechanisms to assist the injured workers and their families, including insurance claims and legal consultation.
Background of the facility
The Zhuyuan Extra High Voltage Substation began operations in 2018 and plays a key role in supplying stable electricity to the Hsinchu Science Park.
To enhance voltage regulation and system stability, Taipower initiated a project in 2023 to install STATCOM equipment, with construction beginning in 2024.
At the time of the incident, the system was still undergoing testing and had not yet been formally commissioned or handed over.
Videos showing thick smoke and flames rising from the site circulated widely on social media platforms, drawing significant public attention.
Local media reported heightened concern over industrial safety, particularly given the proximity of the facility to major semiconductor operations.
