Two main approaches are used. The first assesses the seasonality and variability of renewable energy resources in LA, as well as their possible complementarities. Variability indices are calculated to assess patterns of wind and solar power resources and a statistical analysis evaluates complementarities between hotspots in the region. The second determines possible impacts on the future long-term wind and solar resource complementarities due to climate change for those regions where complementarity was previously identified. For this, results of two General Circulation Models (GCMs) for two Representative Concentration Pathways-RCPs (RCP 4.5 and RCP 8.5) are used. Results show a higher variability for wind power when compared to solar power generation resources both on an hourly and monthly scales. Results also indicate that Brazil can play an important role regarding renewable energy integration in LA, since the country has the strongest capacity to complement and to be complemented by other LA countries. As for the analysis on climate change impacts, results indicate a strong negative impact on the complementarities in the 2071-2100 period, especially for RCP 8.5. These indices describe the fluctuations of a renewable energy resource and/or the energy generated from it throughout its life spam [6]. It is possible to find in the literature indices designed specifically for wind and solar energy. These indices can be classified according to the parameter on which the variability analysis is performed. In the case of wind energy, for instance, the Energy Yield Production Indices, such as the German IWET-Ingenieurwerkstatt Energietechnik [7]are the most commonly used indices. Other índices include the Wind Speed Index, the Wind power density Index and the Wind Energy Production Index from Wind Data [8]. Wind indeces for a specific site also can be calculated based on the site's wind data and turbine's power curves and are often used for the operational verification of wind turbines. Metrics describing and quantifying variability at different time scales are key-factors to a site characterization [9,10]. In the case of solar energy, the variability of solar irradiation depends on the time scale in which it is analyzed. Thus, long-term variability studies are
