Incident Overview
On September 9, an explosion ripped through the Ritom Hydroelectric Station in the village of Piotta, canton of Ticino, killing two workers. Police in Ticino reported that a fire broke out around 9:30 a.m. (0730 GMT) and was quickly followed by an explosion that engulfed the two men. One victim was identified as a 55-year-old Swiss citizen; the second worker has not yet been named. Emergency services, including a Rega helicopter, responded to the scene and confirmed the incident as a “serious accident.” The blast caused extensive damage to the historic building.
Background and Renovation Context
The Ritom facility, more than a century old, is owned by Swiss Federal Railways (SBB) and has been undergoing a major renovation aimed at reconfiguring the site. A new 350 million-Swiss-franc power plant is being constructed adjacent to the old station, with commissioning slated for 2027. The renovation work was part of a broader plan to modernize the hydroelectric complex while preserving its historic structures.
Investigation and Official Response
State prosecutors have opened an investigation into the cause of the explosion. Cantonal police, citing the state broadcaster RSI, indicated that the incident is believed to stem from an electrical problem with a transformer during a commissioning test. Police statements emphasized that the exact circumstances remain under investigation, and authorities are working to determine whether equipment failure or other factors contributed to the fire and subsequent blast.
Impact and Future Outlook
The explosion severely damaged the original plant, halting renovation activities until safety assessments are completed. The loss of two workers has prompted renewed scrutiny of safety protocols on Swiss hydroelectric projects. Despite the setback, the new plant’s construction continues, with the 2027 opening target unchanged, though officials acknowledge that the investigation’s findings may influence future renovation timelines and safety standards.
