The majority of power outages are caused by third-party damage as well as internal causes such as faulty material or network overloads.
A major power outage occurred in Luxembourg on 10 September. In a parliamentary question, MP Marc Spautz from the Christian Social People's Party (CSV) wanted to know why this happened.
A defect affecting the same medium voltage cable occurred simultaneously in two different locations in the Creos network on the night of 10 September, shortly before 4am. In Dudelange, the cable issue affected 14 medium voltage posts with over 1,000 electrical connections, all of which failed. The cable in question was installed in the 1980s and is due to be replaced in 2023.
Creos workers worked alongside the dispatching team to isolate and fix the defects before gradually reconnecting the posts and clients to the network. The blackout lasted four hours.
Two days later, there was another power outage in Dudelange. The outage lasted slightly more than an hour and affected over 1,000 electrical connections.
There were also other incidents on the power grid. On 10 September 2022, for instance, a branch fell on an overhead line between Holtz and Perlé in the municipality of Rambrouch, causing a breakdown in the Redange high-voltage station.
From January 2021 to August 2021, there were 446 power outages, which lasted an average of 167.33 minutes, according to Minister for Energy Claude Turmes. In the same period in 2022, the number of outages decreased to 416 and the duration also decreased to 153.76 minutes/outage.
