A massive nationwide blackout struck the Dominican Republic on Monday, causing severe disruptions to transportation and traffic systems, particularly in the capital city of Santo Domingo. The failure of the National Interconnected Electrical System (SENI) triggered the shutdown of the Paraíso and Isabela substations, which in turn cut power to Lines 1 and 2 of the Santo Domingo Metro and Line 1 of the Cable Car. The Office for the Reorganization of Transportation (OPRET) swiftly suspended services on both systems, ensuring the safe evacuation of passengers from trains and cabins. Authorities confirmed that no individuals were trapped in elevators or stations during the incident.
The blackout also disabled traffic lights at critical intersections in the National District, including Abraham Lincoln, Winston Churchill, and Rafael Augusto Sánchez avenues. This led to severe gridlock during rush hour, exacerbating the chaos. While some intersections remained operational thanks to private backup systems, the majority were left without functioning signals. In response, agents from the General Directorate of Traffic Safety and Land Transportation (Digesett) were deployed to manually direct traffic and mitigate the risk of accidents.
As authorities work tirelessly to restore electricity and stabilize transportation operations, residents of Greater Santo Domingo continue to face prolonged delays and widespread traffic disruptions. The incident underscores the vulnerability of the nation’s infrastructure and the urgent need for robust contingency plans to address such emergencies in the future.
