Overview
- By Wednesday morning, most service was back with remaining outages ranging from roughly 7,000 to about 19,000 users depending on the source.
- Edesur said a fault at the Bosques substation cascaded across multiple sites and that service was brought back in stages.
- ENRE reported cables running above 100% of nominal capacity and stressed transformers, underscoring limited room to operate under peak demand.
- Official outage tallies fluctuated overnight, with the ENRE dashboard briefly nearing one million affected before revising to hundreds of thousands and then tens of thousands.
- Hard-hit areas included Almagro, Recoleta, and Alejandro Korn, as the heat wave pushed late-night demand to critical levels.
