Interfaz substation

Interfaz substation

The Interfaz Substation (230/34.5 kV) is the first project in the system where high-voltage transmission is directly integrated with transformation for end-user delivery. This initiative makes optimal use of the existing infrastructure of the National Interconnected System (SNI), delivering tangible improvements in electric service quality, especially in terms of voltage stability and reduced service interruptions. Status: In commercial operation since 2023
  • Improves energy quality in and around the Municipality of Livingston.
  • It strengthens opportunities for expansion of rural electrification and allows the connection of new users.

La Vega II Substation

The expansion of the La Vega II Substation was carried out as a self-initiated project aimed at increasing the operational capacity of the transmission system. This project enabled the activation of the second circuit of the Aguacapa–La Vega II transmission line, enhancing service reliability and reducing potential bottlenecks in energy flow. The expansion reinforces a key part of the National Interconnected System (SNI), improving the stability and continuity of electricity supply in the region.
Status: In commercial operation since 2019.
