A transformer on Rue Principale in Ernster, part of the commune of Niederanven, caught fire, causing a widespread power outage in the area (the source gives conflicting days for the fire, either Monday or Tuesday afternoon). Creos, the national electricity grid operator, disconnected the transformer from the network for safety reasons. Firefighters brought the fire quickly under control. By that evening, Creos confirmed that power supply had been restored and the underlying issue resolved, though crews remained on site to ensure supply security and carry out remaining work. The cause of the fire had not been determined at the time of reporting. No injuries were reported.

Not reported. The cause of the transformer fire was described by the operator as yet to be determined.

  1. A transformer fire on the distribution network requires quick disconnection to limit spread and protect grid stability.
  2. Fire crews can control a transformer fire rapidly when access is straightforward and fuel load is limited.
