In Colombia, the potential in wind and solar energy is considered high, however, the area of the non-interconnected areas of the country corresponds to approximately 50% of the territory. In particular, in the department of Putumayo there is a low rate of electrical coverage, on the other hand, the solar and wind energy potential is unknown. In this investigation, the effective potential for electricity generation in the department of Putumayo was determined, based on solar and wind resources, considering technical and geographical restrictions. For this purpose, information from multiple databases, such as IDEAM weather stations, and remote NREL and NASA databases was used. It was found that the Amazon region in Putumayo has the highest irradiation and the highest effective solar potential with respect to the other regions (Andean, and AndeanAmazonian); however, winds are the lowest of the 3 regions. On the contrary, in the Andean region the irradiation and effective solar potential values are the lowest. With respect to the wind power density and the energy generated by a turbine, the highest values were in the Andean-Amazon region, this value is small compared to areas of high potential in Colombia. On the other hand, evaluating the energy costs of the region and the global levelized energy costs, it is concluded that the potential with photovoltaic systems would be feasible to produce distributed self-generation and generation electricity in the municipalities of Putumayo.
