​About Nucleoeléctrica Argentina​ Sociedad Anónima (NA-SA)

Nucleoeléctrica Argentina Sociedad Anónima (NA-SA) are the owners and operators of the single-unit Embalse Nuclear Plant. It is one of two nuclear power stations in Argentina currently operational. NA-SA joined COG in 1986.

Nuclear power provides 28 per cent of energy to houses in Argentina. The energy provided by Embalse is supplied to the national grid. On average, Embalse provides enough energy to support the needs of 3-4 million people. 

The energy generated reaches the Argentine Northwest, Cuyo, Center Region, Greater Buenos Aires and Litoral. As well as supplying electricity, Embalse also produces the Cobalt-60 radioisotope used in medical and industrial applications.

In 2019, Embalse returned to service following the completion of a life extension project that will enable the plant to operate for 30 more years.
