Overview

Nucleoeléctrica Argentina S.A. (NA-SA) is an Argentine electricity-generating company focused on nuclear power. The supplied Spanish Wikipedia excerpt identifies it as the operator of the Embalse and Atucha I and II nuclear power plants. Its official website presents the company’s work under the message “Energía nuclear para potenciar el futuro del país” (“Nuclear energy to power the country’s future”) and provides information about its plants, services, news, procurement, and supplier registration. The company’s listed generating assets are Atucha I, Atucha II, and Embalse. The supplied Wikipedia excerpt gives their stated capacities as 362 MW, 745 MW, and 656 MW respectively, and associates them with the years 1974, 2006, and 1984. The company website describes Atucha I as undergoing life extension, while showing Atucha II and Embalse at 100% in the status panel captured in the supplied evidence. These status readings are time-sensitive snapshots, not enduring operating guarantees. NA-SA’s ownership is described in the supplied excerpt as 80% held by Argentina’s Ministry of Economy and 20% by the National Atomic Energy Commission (CNEA). The official supplier portal supports the company’s procurement activities: suppliers can register, consult current contracting opportunities, access tender documents, and submit offers digitally. The website also advertises services and visits to the company’s nuclear plants. The evidence provided does not establish a founding year, founder, headquarters, named consumer-facing product line, or international operating footprint; the company is described here as an Argentine power generator rather than as a retail electricity brand.

History

Nucleoeléctrica Argentina S.A. (NA-SA) is identified in the supplied Spanish Wikipedia excerpt as an Argentine electricity-generating company that operates three nuclear power plants: Atucha I, Atucha II, and Embalse. The excerpt associates Atucha I with 1974 and a capacity of 362 MW, Atucha II with 2006 and 745 MW, and Embalse with 1984 and 656 MW. The evidence does not clarify what event each year denotes, so those years are reproduced as supplied rather than interpreted as construction, commissioning, or commercial-operation dates. The company’s official website presents nuclear energy as a means of supporting the country’s future and provides plant information, services, news, supplier resources, and visitor information. In the homepage snapshot supplied, Atucha I is described as undergoing life extension, while the listed operating-status figures for Atucha II and Embalse are 100%. These are snapshot details and may change over time. The supplied excerpt describes the company’s ownership as 80% Ministry of Economy and 20% CNEA. Its official supplier portal enables registration and access to current contracting opportunities and tender documents; the portal also describes digital offer submission and states that the functionality would become mandatory from 17 February 2021. The excerpt names Juan Martín Campos as president, Germán Guido Lavalle as vice president, several directors, and Marcelo Famá as general manager; these names are reported as source-listed authorities and are not independently verified as current. The available evidence does not establish a founding date, founder, headquarters, or a fuller corporate chronology.
