Transmisión eléctrica en Colombia: Panorama 2025

This report provides an analysis of Colombia's electrical transmission sector as of 2025, highlighting a structural lag in infrastructure relative to the expansion of renewable energy generation and significant execution delays in key projects.

• Colombia's electrical generation capacity is projected to reach 38.9 GW by 2030, consisting of 20.9 GW of current total installed capacity and 18 GW of additional approved capacity.
• The National Interconnected System (SIN) is reaching its operational limits, with less than 5% of transport capacity available. Furthermore, 90% of substations are expected to exhaust their short-circuit interruption capacity within the next 5 years, which threatens the integration of new generation projects.
• Project execution is a primary challenge, with 55% of the 20 transmission projects currently underway experiencing delays. Some projects have been delayed for a decade or more, specifically Bacatá-Norte (12 years) and Sogamoso Norte-Nueva Esperanza (10 years). These delays are attributed to licensing and permit difficulties, socio-environmental factors, and poor coordination between national energy planning and land-use planning instruments.
• The 'Plan Maestro de Modernización y Expansión de la infraestructura de Transmisión Eléctrica' identifies 98 strategic works; completing 44 of these could resolve over 149 operational restrictions projected for the 2024–37 period. Additionally, in 2025, the UPME formally adopted the Modelo de Relacionamiento Territorial to better integrate cultural, social, and environmental criteria into sector planning.
