Sources: 2. Developments: 2. Emergency management exercises have been conducted in Germany and Austria to test disaster preparedness and inter-organizational cooperation. In Zolling, Germany, approximately 700 responders participated in the ‘High Voltage 2026’ exercise. This simulation modeled a gas cylinder explosion at a music festival, creating approximately 170 simulated casualties. The drill involved the Red Cross, Johanniter-Unfall-Hilfe, Malteser, local fire departments, and police, with the Freising Clinic establishing a dedicated second emergency room to manage the simulated influx of victims. In Wolfsberg, Austria, the ‘COMBINED SUCCESS 2018’ exercise focused on a sudden, long-term, and supra-regional failure of the electrical power supply. The simulation tested the impact of a blackout on critical infrastructure and official emergency command structures. During the exercise, the AMRS Wolfsberg amateur radio station supported emergency services by establishing a lead station at the main Wolfsberg fire station to maintain regional and supra-regional connections. ## Timeline ### 2026-10-24: Wolfsberg conducts blackout emergency preparedness exercise The Wolfsberg District Authority conducted the ‘COMBINED SUCCESS 2018’ exercise in Carinthia, simulating a major regional blackout to test emergency response and amateur radio communication support. 2 sources. https://clstr.news/cluster/wolfsberg-conducts-blackout-emergency-preparedness-exercise ### 2026-09-26: Zolling hosts large-scale emergency response exercise Around 700 emergency responders conducted the ‘High Voltage 2026’ disaster drill in Zolling, simulating a music festival explosion with 170 simulated casualties. 3 sources. https://clstr.news/cluster/zolling-hosts-large-scale-emergency-response-exercise --- Cite as: European emergency response preparedness exercises.
