- 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.

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.
