What do we know about the historic power outage that left 50 million people without light?

The government explained that one of the causes was a malfunction of the interconnected system operating with a 500 kV line (Colonia Elía – New Bell) out of service due to the relocation of a tower to the Paraná Guazú river crossing. This line is one of those that carry energy from the power stations of Yacyretá and Salto Grande to Buenos Aires. "

The preliminary report he had access to L M N, said that at that time "there was a short circuit on the line 500 kV Colonia Elía-Belgrano, parallel to that cited, and for reasons that are under investigation, the line Mercedes -Colonia Elía at 500 kV was won ".

"By being the line Colonia Elia-Nueva Campana unavailable, the system is ready to support the disengagement of another 500 kV line, in this case two lines disengaged simultaneously. This abnormal weakening of the transmission network has probably destabilized the Yacyretá and Salto Grande power stations and their contribution has been lost (around 3,700 MW), "he said.

In this sense, the Secretary of Energy, Gustavo Lopetegui, said the final report with the reasons for the reduction would be in 15 days, added that it should not be repeated and that there would be penalties.

"Companies must submit the reports and we will see what happened because the repairs must be paid," he said Monday, while the whole country was enlightened.

In Neuquén, the service returned after 19:30, after the Neuquén Provincial Energy Agency (EPEN) made the decision to opt for the alternative route to the national interconnected grid. "In Neuquén and in the zone of influence, we are already connected in 132 Kv to El Chocón and we are doing the same thing with Planicie Banderita", they said in a statement.

EPEN's decision was adopted after a new Transener maneuver that failed to connect the Comahue area to the 500 Kw system.

Other countries

The blackout in Argentina has had repercussions in neighboring countries. The National Administration of Power Plants and Transmissions of Uruguay (UTE) declared that a "fault in the Argentine network" affected the interconnected system "leaving the entire national territory without service, as well as several provinces of the neighboring country" .

The cut arrived in Paraguay where "the blockade of seven units of the Yacyretá hydroelectric plant", shared by Paraguay and Argentina, caused a cut in the southern cities of Ayolas, Pilary Villaldín, according to the National Administration of Electricity (ANDE) in a statement.
