What happened
A fire broke out at about 05:26 on a Wednesday morning in September 2024 at the Wesernetz Blockland substation on Hemmstraße in the Findorff district of Bremen, Germany. An oil-filled transformer holding about 48 tonnes of oil was fully alight, with flames reaching up to 30 metres high. Bremen fire service attended. Smoke caused an odour nuisance in the area, and several emergency calls were received beforehand. Authorities issued a hazard alert through the NINA warning app at about 06:20, stating there was no immediate danger to residents.
The fire was extinguished around 07:30, and clean-up took several hours. No injuries were reported, no power outage was reported in the affected area, and the cause is still under investigation.
Contributing factors
Not reported. The cause of the fire is still being investigated.
Lessons learned
- Oil-filled transformers need fire-protection measures, oil containment and adequate separation from other equipment and neighbours, so that a fire in one unit does not spread or create a large smoke plume.
- Operators should agree in advance how the public is alerted, including warning apps and clear guidance on smoke and odour, so that residents receive timely information.
- Protective systems and condition monitoring for transformers should be checked regularly, so that faults that could lead to a fire are found before they escalate.
