Overview
- Officials said a fault at Edenor’s Morón high‑voltage substation disconnected four 220 kV lines, cutting roughly 3,000–3,311 MW from the system.
- ENRE reported a simultaneous peak of 840,392 users without power and tallied 934,060 affected in total, with outages spanning Edenor and Edesur areas.
- Edenor reported that more than half of affected users were restored within 30 minutes and over 90% within an hour, though localized cuts persisted in some neighborhoods.
- Public services were disrupted as Subte Line D halted, Line H ran with delays, Mitre branches and the Tren de la Costa were suspended, many traffic lights failed, and Aeroparque saw limited power issues without flight impacts.
- AySA warned that water production and distribution would recover gradually and urged responsible use, while inspections at Morón continue and experts pressed for the AlmaGBA battery rollout and a new privately financed transmission line.
