What changed
The State sold ENARSA's stake in CITELEC S.A., the company that controls 52.65% of Transener (the country's largest high-voltage power transmission company, which in turn controls Transba). ENARSA held 50% of CITELEC; the other 50% belongs to Pampa Energía. Res. 673/2026 awarded National and International Public Tender 504/2-0002-CPU25 to the consortium of Edison Transmisión S.A. (CUIT 30-71934447-6) + Genneia S.A. (CUIT 30-66523411-4) for USD 356,174,811.78 excluding VAT. Three bidders: Edison-Genneia (1st, USD 356.2 M), Central Puerto (2nd, USD 301 M) and EDENOR (3rd, USD 230 M). The resolution declares the bids reasonable per BICE's appraisal and 'above the established floor price', without disclosing the floor figure (the ~USD 206 M cited in a press headline comes from a single source, with no primary backing). Res. 130/2026 of ENReGE later authorized the change of control with safeguards: regulated tariffs (Law 24,065), grid expansions subject to public hearing and regulatory approval, guaranteed open access. verif · May 12, 2026 ↗

The high-voltage power transmission sector; wholesale market (MEM) operators and large users that depend on the Transener/Transba grid; investors in energy infrastructure; transmission suppliers and service companies (towers, transformer stations, line maintenance).

Our reading
The program's first energy privatization closed with real competition (three top-tier bidders) and at a price above the floor: the State collected USD 356 M and a strategic company moved to private management with regulated tariffs and open access. Legal certainty that organizes investment in power infrastructure (R2 · the RIGI promise is kept). thesis
Where it lands, province by province3
Neuquén The basin's electrical bottleneck — the one the province is trying to unblock with its own borrowing for power works — hangs on the high-voltage grid Transener controls. With the asset in private hands, regulated tariffs and open access, expansions come to be decided on return and contracted long-term. The other 50% of CITELEC belongs to Pampa, which also holds Rincón de Aranda in the Neuquén RIGI portfolio. favorable stability → long-term investment thesis
Río Negro The trunk network that carries power out of the Comahue crosses Río Negro, and its operation passes to a private owner with regulated tariffs and guaranteed open access. It is the counterparty the province's two open ends need: evacuating Cerro Policía's 300 MW from the plateau and supplying the coast's new industrial demand. favorable stability → long-term investment thesis
San Juan The works that unlock all three copper projects at once — the 500 kV Rodeo-Chaparro line, 167 km — has its public convenience and necessity certificate issued to Transener at Vicuña Argentina's request (ENReGE 330/2026). That transmission company has just changed hands: execution of the physical bottleneck of the San Juan boom now sits with a private consortium with capex logic, and the risk shifts from permitting to schedule. mixed opening and deregulation thesis
