Major Blackout Hits Mar del Plata After 132 kV Distribution Failure

EDEA reported crews had restored roughly half the city's supply by 8:40 AM with technical teams continuing repairs to return power to remaining neighborhoods.

Overview

  • A widespread blackout began around 7:00 AM Sunday after a failure in the 132 kV distribution network and left thousands of users without electricity.
  • EDEA said it deployed technical teams to the field and announced that by about 8:40 AM roughly 50% of service in Mar del Plata had been restored.
  • The outage disabled traffic lights and street lighting, forcing drivers to take extra caution at intersections and prompting some businesses to open later than usual.
  • EDEA asked customers to report ongoing outages through a free hotline (0800-666-3332), WhatsApp (223 634-3332) or the company website while repairs continue.
  • The company described the fault as occurring in a high-voltage 132 kV line that feeds local substations, a type of failure that can cut power to wide areas until crews isolate and re-energize affected segments.
