The combination of Geographic Information Systems (GIS) and Multicriteria Decision Analysis (MCDA) methods can bring several benefits for the solution of real-world planning and management problems. Under that view, this work aims to evaluate alternatives for the location of Thermoelectric Power Plants (TPP) produced in a GIS environment using a MCDA technique for supporting the decision-making process. The proposed model is a contribution for the TPP site selection process, which is a difficult and complex task due to the several economic and environmental criteria it involves. The visualization of the analysis outcome in GIS maps helps to demonstrate the suitability of MCDA techniques for planning the expansion of the electric supply system. In addition, the selection of a specific technology for the installation of the TPP in the real case application is used to show scenarios with different risk levels, which range from minimum to maximum risk conditions, also including the intermediate case of total trade-off.
