The Electric Transmission System Plays A Crucial Role To Foster A Sustainable Energy Transition. However, The Construction of New Transmission Infrastructure is a Big Issue, Not only in Ecuador, but also globally. As Such, The Current Transmission Network Expansion Planning (TNEP) Decision-Making Process, to Weakness in Today's System Planning, needs to be improved. Therefore, Having APPROPRIATE DECISION-MAKING TOOLS THAT CAN SUPPORT STAKOLDER`S INTERACTION, CAN HELP TO SPEED UP Agriculture Communities in Ecuador. The Outcome of the Project Aims at Improving The Decision-Making Process for Transmission Expansion Planning by providing optimization models, Considering Socio-Environmental, Technical and Economical Constraints. The Project Involves to Multistakeholder and Multidisciplinary Decision-Making Approach to influence Approprot Policies and Practices To Reure Access to Affordable, Reliable, Sustainable and Modern Energy for All.
