Europe is taking seriously the growing risk of a major power outage amid heightened tensions with Russia. Concerns over potential sabotage and cyberattacks targeting critical infrastructure have prompted preventative measures. France is planning a large-scale crisis simulation exercise in 2027 to prepare for such an event. While officials acknowledge a complete blackout is not inevitable, they emphasize the necessity of preparedness. The exercise aims to assess vulnerabilities within the European power grid and strengthen response capabilities. This proactive approach highlights the increasing awareness of energy security as a key national and continental priority. The scenario reflects a broader concern about hybrid warfare tactics targeting essential services.
