Buenos Aires provincial authorities are mounting legal and political opposition to the federal government’s plan to privatize 44% of Nucleoeléctrica Argentina S.A. (NASA), citing dramatic undervaluation of the state-owned operator of the country’s three nuclear plants. The dispute centers on a valuation methodology that provincial officials characterize as deliberate asset-stripping, with the National Valuation Tribunal pegging the company’s worth at $6 billion to $13 billion against a proposed sale price of $500 million to $1 billion. The confrontation marks an escalating provincial-federal conflict over strategic energy infrastructure control ahead of the 2027 electoral cycle.
