What Redinter does

Redinter (legal name Red Eléctrica Internacional S.A.) is the Chilean operating subsidiary of Redeia, the Spanish electricity transmission group, founded in Chile in 2015. The company develops, operates, and maintains high-voltage electricity transmission infrastructure (220 kV and 400 kV lines and substations) across northern Chile through three concession entities: REDENOR (69.9% owned), REDENOR 2, and TEN (50% joint venture with ENGIE Energía Chile). Together these entities manage 1,776 km of circuit across the Arica y Parinacota, Antofagasta, Tarapacá, and Atacama regions. Redinter's most strategically significant asset is TEN's 600+ km Mejillones-Cardones line, which physically interconnected Chile's previously separate northern (SING) and central (SIC) grids into a unified National Electrical System (SEN).

The company's core business is regulated transmission services, with revenue derived from formula-based tariffs set by Chilean authorities under the ley de transmisión eléctrica, producing an annuity-like income stream from its concession portfolio. Redinter complements its physical assets with proprietary digital platforms developed in collaboration with Redeia's technology subsidiary Elewit and partners Aerolaser System and Ampacimon. DALIA is a SaaS platform for LiDAR and image-based aerial inspection of transmission lines with AI-powered anomaly detection; PDEye is an AI platform that interprets partial discharges in critical assets (cables, GIS compartments, power transformers) to support predictive maintenance. Redinter also co-developed the Nexpertia smart monitoring platform with ENGIE Energía Chile.

Redinter's go-to-market is enterprise and government oriented: revenues flow through regulated tariffs administered by the Coordinador Eléctrico Nacional (CEN), with new concession growth pursued via public international tenders (e.g., Decree Exento No. 266/2024 for the Nueva Pozo Almonte-Roncacho expansion). The company is positioned as the Chilean vehicle of Redeia's broader Latin American transmission strategy, which also includes operations in Peru and Brazil (via Argo Energia), with Redeia having committed more than 200 million euros to organic growth across the region. Major customer segments include the Chilean Ministry of Energy, the CEN, large mining operators in northern Chile, ENGIE Energía Chile, and regulated energy consumers served through the National Electrical System.

Direct peers

• Transelec S.A. Chile's largest electricity transmission system operator, managing over 10,000 km of high-voltage lines and substations across the country. Direct competitor to Redinter in the Chilean regulated transmission concession market, particularly in northern Chile.
• Interchile: Chilean transmission subsidiary of Colombia's ISA (Interconexión Eléctrica), operating 220 kV and 500 kV lines connecting the SIC and SING systems. Competes with Redinter's TEN on the same high-voltage corridor and targets the same Chilean regulatory concession framework.

Broad incumbents

• Redeia (Red Eléctrica Corporación): Spanish electricity transmission group and Redinter's parent company. Operates as TSO in Spain (parent's home market) and globally via subsidiaries, providing the closest direct read-across for Redinter's regulated transmission business model and tariff framework.
• ISA (Interconexión Eléctrica S.A.): Colombian multi-Latin American TSO with operations across Colombia, Chile (via Interchile), Peru, Bolivia and Brazil. Comparable for its diversified Latin American regulated transmission footprint and concession-based business model.
• Enel Chile: Chilean subsidiary of Italy's Enel, operating one of the largest distribution networks and renewable generation portfolios in Chile. Overlaps with Redinter in the broader Chilean electricity value chain, particularly around grid stability and renewable integration.
• AES Andes: Chilean power generator and renewable energy developer (formerly AES Gener), a subsidiary of AES Corporation. Operates large-scale generation connected to the same SEN grid that Redinter serves, providing partial overlap on transmission-related grid integration projects.

Emerging players

• Celeo Redes: Latin American transmission operator with concessions in Chile, Peru and Brazil. Emerging player with a meaningful regional footprint that competes with Redinter for new concession rounds across the same Andean markets.

Regional players

• ENGIE Energía Chile: Chilean subsidiary of global energy major ENGIE, one of Chile's largest generators and Redinter's 50/50 JV partner in TEN. Comparable as a complementary energy player operating across Chile's electricity value chain, including generation and transmission infrastructure.
• Sempra Infrastructure: North American infrastructure platform with energy operations in Mexico and LNG export infrastructure in the US. Comparable as a regulated/contracted infrastructure operator in adjacent Latin American markets with similar long-duration capital-intensive utility assets.
• CGE (Compañía General de Electricidad): Chilean electricity distribution company serving millions of customers across the country. Adjacent peer operating in the regulated energy infrastructure space in Chile, with a different focus on distribution rather than high-voltage transmission but interacting with the same grid ecosystem.
