What ISA Intercolombia does

ISA Intercolombia (legal name: Intercolombia S.A. E.S.P.) is a regulated high-voltage electricity transmission utility operating in Colombia as a subsidiary of ISA Group. The company transports electrical energy at voltages ranging from 230kV to 500kV through an extensive network of overhead and underground transmission lines and electrical substations across multiple Colombian departments including Cesar, Norte de Santander, Santander, Bolívar, Huila, Tolima, and the Caribbean region. Core technical capabilities include HVDC transmission technology, the first 500kV underground transmission segment in Colombia (at Parque Solar Atlántico), 15km of 220kV underground cabling at the El Río project, and digital substation modernization under the Renovación Betania initiative.

The business operates under CREG regulatory oversight as a Sociedad de Economía Mixta (mixed-capital public utility company), generating revenue through regulated transmission tariffs and connection fees. Primary customers include energy distribution utilities, power generation companies (including renewable energy developers), and government entities, with additional social investment programs supporting rural electrification in underserved communities. Active capital projects span five major interconnections: Pasacaballos (220kV), La Loma-Sogamoso (500kV, traversing 18 municipalities), Carrieles (230kV), El Río (220kV), and Cerromatoso-Chinú-Copey (500kV).

Strategic positioning emphasizes Colombia's energy transition through renewable integration, infrastructure modernization, and sustainability programs including environmental compensation (170,000+ native plants restored), community education via the Aula Virtual platform, and strategic alliances with regional planning entities such as RAP Caribe and environmental authorities including CORANTIOQUIA and Terrasos. Headquartered in Medellín with 1,001-5,000 employees, the company holds ISO 9001 and ISO 14001 certifications and maintains CREG 080 of 2019 compliance.
