How much electricity Argentina's nuclear power plants supplied in the first half of the year

Argentina's nuclear power plants generated 4,450,355 MWh of electricity during the first half of 2026. The figure represents more than 7% of the energy produced in the country over that period and confirms the role of nuclear generation within the national electricity system.

That volume is enough to supply millions of people. According to electricity market data, the nuclear contribution covered 13% of the country's residential demand during the six-month period, a scale that shows its presence in the daily life of Argentines.

The result carries added value. It was achieved with two plants in operation, Atucha II and Embalse, while Atucha I moves ahead with its Life Extension Project, the work that will prepare it to deliver electricity to the grid again over the coming decades.

Nuclear generation stands out for its continuity. The plants run around the clock and in any weather, providing baseload power, the kind that sustains the electricity system at all times.

Behind every MWh there is daily work involving operators, technicians and professionals from a range of specialties, with safety and reliability as the guiding criteria of the entire operation.

With this performance, nuclear energy reaffirms its place among the sources that secure the country's electricity supply, today and in the years ahead.
