- The voltage levels in the transport system will increase, thus improving the quality of service, not exceeding the limits established in the applicable technical standards.
- In general terms, a significant reduction in power losses in the system will be experienced, reducing the operating costs of the system.
- The construction of the project began in 2022 and it is expected to begin its commercial operation in 2024.

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
