Buenos Aires, Argentina - March 03, 2025 The lights — and air conditioning — went out at the Casa Rosada on Wednesday afternoon as swaths of Buenos Aires City were hit with a power outage in 30°C heat. The energy distribution company Edesur suffered two power failures in a day, halting the subway and leaving thousands without electricity. “The current outage is due to a failure in two 220 KV high voltage lines of Costanera-Hudson which belong to the electricity distribution company Edesur. It’s affecting the south of Buenos Aires City and Greater Buenos Aires,” read a communiqué from the Energy Secretariat on the afternoon power cut which started at 12:40 p.m. Edesur had suffered a similar blackout in the early hours of Wednesday, which stopped the subway, darkened traffic lights and left 622,000 people without power. The secretariat reported that 366,000 homes were left without electricity in the second power outage in the afternoon. Edesur reported at 4:30 p.m. that the company had restored power to 70% of the affected users.
