- Compañía de Transporte de Energía Eléctrica en Alta Tensión Transener S.A. (Transener) operates as Argentina's leading provider of extra high-voltage electricity transmission services, managing the national extra high-voltage network under a 95-year concession granted upon privatization in 1993 with headquarters in Buenos Aires. The company owns and maintains approximately 12,400 kilometers of high-voltage transmission lines at 500 kV and 220 kV along with 53 substations, plus an additional 6,228 kilometers of 220 kV, 132 kV, and 66 kV lines and 112 substations operated by its subsidiary Transba S.A., which handles trunk distribution in the Province of Buenos Aires serving around 39% of Argentina's population; Transener also supervises grid expansions by independent transmitters covering the remaining network, provides engineering and consulting services, testing and commissioning, operation and maintenance for third parties including construction-operation-maintenance contracts, technical assistance, equipment installation and training, and dark fiber leasing via communications facilities. Transener serves key wholesale electricity market participants such as generators, large users, distributors, and international interconnectors across Argentina with primary customers including Minera Alumbrera Ltd., AES Argentina Generación S.A., Nucleoeléctrica Argentina S.A., Silica Networks Argentina S.A., and Capex S.A., while its operations remain regulated by the Ente Nacional Regulador de la Electricidad (ENRE) as a subsidiary of Compañía Inversora en Transmisión Eléctrica Citelec S.A. In 2025, Transener underwent a comprehensive Five-Year Tariff Review process culminating in significant adjustments starting May 2025 with initial 42.89% increases phased monthly through December alongside index-linked mechanisms based on consumer and wholesale prices, including subsequent hikes such as 7.25% in June, 4.64% in July, 6.02% in August, 6.95% in September, 7.12% in October, and 7.61% in November; the ENRE granted partial reconsiderations in August modifying cost structures and investment plans for the May 2025-April 2030 period without altering total revenues, while Transener advanced capital expenditure commitments totaling AR$88,726 million as of September 30, 2025, supervising major projects like Olavarría and Ezeiza substation repowerings, new San Juan and Ramallo substations, and various Transba expansions such as Ayacucho and Cangrejales substations; additionally, the National Securities Commission authorized a USD300 million global bond issuance program in October 2024.
