Projects

Main text: With an installed capacity of 75 MVA, the Modesto Méndez Substation features state-of-the-art technology at 230/69 kV, along with a 34-kilometer transmission line. This infrastructure marks a milestone in strengthening Guatemala’s power transmission system, particularly in the Petén department, significantly improving electric power quality and the end-user experience. Status: In commercial operation since 2024.

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

These systems were identified as part of the effort to expand electric transmission capacity, with the goal of mitigating network constraints and providing greater operational flexibility to the Wholesale Market Administrator (AMM). Their integration directly contributes to enhancing the efficiency and stability of the national power system. Status: In commercial operation since 2022.

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.

The Pacific South Ring (APS) is the first fully integrated electric power transmission project in Guatemala to reach 100% commercial operation. Its design, construction, and energization were carried out as a self-initiated project, approved by the National Electric Energy Commission (CNEE). The APS is part of the Transmission System Expansion Plan 2012–2021, representing a major milestone in the development of the national electric grid. Status: In commercial operation since 2018.
