Overview
- The failure disconnected four 220 kV lines in the Morón–Rodríguez corridor and stripped roughly 3,000–3,311 MW from the system during the afternoon peak.
- Real‑time ENRE data showed a simultaneous peak of about 840,392 users without power, with total affected across Edenor and Edesur reported around 900,000 to 1,000,000.
- Edenor said more than half of impacted customers were reconnected within 30 minutes and over 90% within an hour, as Edesur reported knock‑on outages from the interlinked grid.
- Emova confirmed all subway lines returned to normal operations after checks, with earlier disruptions on several trains and limited impacts at Aeroparque that did not halt flights.
- AySA warned of low water pressure and gradual network re‑pressurization, while intermittent outages of ENRE and operator websites and expert calls for projects such as AlmaGBA batteries and new transmission lines highlighted structural needs.
