A massive power outage struck the Buenos Aires Metropolitan Area on a Saturday night, affecting between approximately 600,000 and 1.5 million people. The disruption, which began around 19:47 local time, impacted Edenor and Edesur customers, causing failures in street lighting and traffic signals. Emergency services were deployed to assist individuals trapped in elevators. Edenor attributed the cause to a malfunction in a 220 kilovolt circuit breaker at the Malaver substation, while Edesur noted the failure was external to its own network. Most services were restored by the following morning. Following this incident, several regions in Argentina have scheduled power outages to facilitate electrical grid maintenance and infrastructure upgrades. In América, planned interruptions were announced for the replacement and enhancement of a distribution substation. In Córdoba, multiple scheduled outages were reported for maintenance of the primary distribution network, equipment installation, and technological updates to transformer substations, affecting various residential and industrial zones. Recent utility disruptions have expanded across other provinces. In Neuquén, Junín de los Andes is experiencing an unplanned power outage in both urban and rural areas caused by a fault in a 33 kV line, with the Ente Provincial de Energía del Neuquén (EPEN) working to resolve the issue during severe weather in the Andean region. Additionally, in Río Negro, Aguas Rionegrinas (ARSA) reported reduced water pressure in Cipolletti following an unexpected collapse during repair works on Santa Cruz Street. Utility disruptions continue in Argentina, with the Empresa Provincial de Energía de Córdoba (EPEC) scheduling further electricity cuts in locations including Alto Alegre, Ballesteros, and Córdoba for maintenance and technological updates.
