This article investigates the crucial role of geospatial considerations in the strategic planning and expansion of electricity transmission networks within the unique geographical context of the Andean region. It delves into how the rugged mountainous terrain, diverse ecosystems, and susceptibility to natural hazards significantly influence the design, cost, and resilience of transmission infrastructure. The paper reviews advanced Transmission Expansion Planning (TEP) methodologies, including AC models and AI-driven approaches for managing uncertainties, and specifically highlights their adaptation to Andean realities through the integration of topographical, geological, and hydrological data. The results demonstrate that a geospatial-informed approach leads to more robust network designs, enhanced resilience against seismic events and climate change impacts, and optimized cross-border interconnections. While acknowledging challenges such as data availability and modeling complexity, the discussion emphasizes the necessity of multi-criteria decision-making and regional collaboration. Future directions include leveraging advanced AI/ML, refining climate change resilience modeling, and fostering supportive policy frameworks to ensure sustainable and adaptable electrical grids in the Andes.
