Overview
- A failure around 14:45 at the Morón 220 kV substation knocked four high‑voltage lines out of service, cutting about 3,000 MW, according to official data.
- Edenor said the incident compromised nearly one‑third of its demand and propagated into areas served by Edesur across the northern and western AMBA.
- Staged restoration returned electricity to more than half of affected users within 30 minutes and to over 90% within the first hour, with some localized intermittent cuts lingering.
- The outage disrupted city services and transport, blacking out traffic lights, halting Subte Line D, delaying Line H, and briefly affecting operations at Aeroparque Jorge Newbery.
- ENRE advised users to file free complaints via its website, 0800‑333‑3000 or 0800‑345‑6000, or in person at Suipacha 615, with documentation and eligibility for bill credits after outages over 15 consecutive hours or four interruptions in one month.
