This work presents a geospatial computational tool-GeoLCOE-for estimating the levelized cost of energy (LCOE) of multiple power generation technologies in Colombia. This tool is designed for assessing both economically and technically new generation projects across the Colombian geography. This tool computes the LCOE of renewable and non-renewable generation technologies for multiple locations based on geospatial data of energy resources. GeoLCOE allows to identify promising places for the construction of new generation projects. The objective of this tool is to provide the Colombian planner with additional assistance for the generation expansion planning.
