Heat and Storms Strain Argentina’s Grid as Córdoba Restores Power and Rosario Strengthens Readiness

Sanctions signal pressure on distributors to fix overloaded networks.

Overview

  • Epec reports around 25 fallen poles along Ruta 9 Norte near Los Llanos and Estación Juárez Celman and has reinforced repair crews while prioritizing areas with essential services.
  • During the Jan. 1 storm in Córdoba, 23 of the utility’s 420 medium‑tension distributors were affected as wind, hail and prior heat stressed insulators and conductors.
  • National regulator ENRE attributes the Buenos Aires metropolitan outages to failures in installations under Edesur’s responsibility and cites cables operating above rated capacity with transformers severely overloaded.
  • ENRE recorded 108 sanctions in 2025 totaling 53,750 million pesos, with credits applied to users and a higher share of penalties falling on Edesur than Edenor.
  • EPE in Rosario says it is better prepared for the customary February demand peak after roughly 80,000 million pesos in investments, including station upgrades and replacement of aging high‑tension cables.
