Power outages affected more than 7000 users in the Buenos Aires metropolitan area minutes before 10 p.m. on Friday. Edesur's concession area was the hardest hit, with low voltage reports linked to heat and maintenance works. Storms are expected to arrive earlier than anticipated on Saturday, December 13, in the region, according to the National Meteorological Service.
On the night of Friday, December 12, 2025, the Buenos Aires metropolitan area (AMBA) experienced power outages that left more than 7000 users without electricity, according to TN reports. These incidents occurred minutes before 10 p.m. and are mainly attributed to intense heat and electrical grid maintenance works. Edesur's concession area, covering much of the Capital Federal and suburbs, was the most affected, with numerous low voltage complaints in homes and businesses.
The extreme heat has strained the power system, worsening existing issues. While initial reports varied between 5000 and 7000 users, the scale of the disruption is evident in the area. No injuries or major damage were reported, but the outages disrupted evening routines in a region already burdened by high temperatures.
In weather context, the National Meteorological Service (SMN) warns that storms forecast for Saturday, December 13, are advancing, with precipitation expected in the coming hours in AMBA. This could worsen the electrical situation if strong winds or heavy rain impact infrastructure. Authorities recommend caution for potential additional interruptions.
