- Compañía de Transporte de Energía Eléctrica en Alta Tensión Transener S.A. is an Argentina-based regulated utility company primarily engaged in the transmission of high-voltage and extra-high-voltage electricity. Founded in 1993 and headquartered in Buenos Aires, Argentina, the company holds the concession for the national extra-high-voltage transmission grid, transporting the vast majority of electric power generated across the Argentine Interconnection System (SADI). Transener operates under the parent holding company Citelec S.A., which is co-owned by Pampa Energía S.A. and state-owned Energía Argentina S.A. (ENARSA), and serves power generators, distribution companies, and large industrial consumers. The company operates through two primary segments: High-Voltage Transmission and Trunk Distribution Transmission. Transener’s core products and services comprise the operation, supervision, and dispatch management of 500 kV extra-high-voltage transmission lines; preventive, predictive, and corrective maintenance of high-voltage transmission networks operating at 500 kV, 220 kV, and 132 kV; operation, testing, and maintenance of high-voltage transformer substations, switchgear, shunt capacitor banks, and reactive power compensation equipment; engineering, construction management, supervisory oversight, and commissioning for transmission infrastructure expansions; specialized technical consulting, power flow simulations, grid connection studies, and regulatory and tariff advisory services for third-party electricity operators; and the deployment, maintenance, and integration of supervisory control and data acquisition (SCADA) systems, remote terminal units, automated protection schemes, and telecommunications infrastructure. Through its majority-owned subsidiary, Empresa de Transporte de Energía Eléctrica por Distribución Troncal de la Provincia de Buenos Aires S.A. (Transba S.A.), the company also operates regional trunk transmission networks across the Province of Buenos Aires, managing a combined national transmission infrastructure spanning over 15,000 kilometers of lines. In recent developments, Transener transitioned into the 2025–2030 Five-Year Tariff Review (RQT) framework administered by the National Electricity Regulatory Entity (ENRE), which instituted comprehensive tariff recalculations and implemented monthly inflation-indexed adjustment formulas based on consumer and wholesale price indices. ENRE also approved the formal consolidation and assignment of the operation and maintenance concession for the Choele Choel–Puerto Madryn transmission line to Transener. Furthermore, the company initiated a multi-year capital expenditure program dedicated to substation repowering and grid reliability projects, including major capacitor bank installations at the Ezeiza and Olavarría substations, and secured regulatory approval from the Comisión Nacional de Valores (CNV) for a Global Bond Issuance Program of up to USD 300 million to optimize its capital structure.
