In late March 2023, a sabotage attack on the power supply of a pumping station for the Transalpine Pipeline near Terzo di Tolmezzo, Italy, disrupted crude oil flows to Germany’s largest refinery at Miro, affecting fuel supplies across southern Germany for several days.
In late March 2023, an attack on the power supply of a pumping station near Terzo di Tolmezzo in the Italian Alps caused an outage in the Transalpine Pipeline, halting crude oil deliveries to the Miro refinery near Karlsruhe, Germany, for three days. The disruption also affected Bayernoil's facilities in Neustadt and Vohburg, Bavaria. German authorities were informed by Italian counterparts and suspect sabotage. The German Interior Ministry and local Italian police are investigating whether this was a politically motivated attack on critical infrastructure. The Miro refinery, which supplies fuels and heating oil to around 10 million people and covers roughly 45% of Baden-Württemberg’s primary energy demand, had to rely on local storage and confirmed no immediate consumer fuel shortages occurred. The incident highlights vulnerabilities in Germany’s energy infrastructure at a sensitive time with emerging jet fuel bottlenecks and reliance on imports for around 36% of diesel. It remains unclear how long Miro could have operated on stored fuel alone. The pipeline and power supply have since been repaired and flows are gradually returning to normal.
Confidence: High
The event describes a confirmed sabotage attack on critical energy infrastructure in Italy that directly impacted fuel supplies in Germany, with law enforcement investigations ongoing. This constitutes an aggressor hybrid warfare signal. There is no indication in the report of defensive or preparatory countermeasures at this time.
