A widespread power outage affected the city of Buenos Aires and several areas of its metropolitan region on Tuesday, leaving more than 45,000 households and businesses without electricity during a period of extreme heat, according to official data and media reports.

The blackout occurred as high temperatures drove a surge in electricity demand, fueled by the extensive use of air conditioners and fans. Residents across the capital and surrounding districts reported service interruptions lasting several hours, with social media users sharing images and videos showing darkened homes, streets, and public spaces.
Figures released by Argentina’s National Electricity Regulatory Entity (ENRE) show that outages increased sharply during the afternoon, particularly in zones serviced by the utility company Edesur. Between 15:35 and 15:55 local time, the number of affected users rose by nearly 10,000 in each reporting interval.

The peak was registered at 16:30, when 2,390 Edenor customers and 42,957 Edesur customers were without power, totaling 45,347 homes and businesses amid extreme weather conditions. Although partial restoration efforts were later initiated, the number of outages climbed again around 18:50, with 41,722 users still without service. The figure declined to 34,841 by 20:50, while power cuts in southern areas reappeared during the early morning hours.
Edesur attributed the outage to a problem at the Bosques Substation, which had cascading effects on several substations serving both the federal capital and the surrounding urban areas. “Our technical teams are already working in the area,” the company said in a statement posted on X, adding that “the supply will be restored in stages.”
The blackout coincided with an ongoing heat wave affecting Buenos Aires city and the province of Buenos Aires. Argentina’s National Meteorological Service issued an alert for temperatures exceeding 30 degrees Celsius, forecasting a maximum of 39°C and a minimum of 27°C in the capital on Wednesday.
The national government has extended the energy emergency and continues to monitor the situation through ENRE, as repeated power cuts highlight persistent vulnerabilities in the electricity system during periods of extreme heat.
