Vulnerability to climate change and adaptation measures of the hydroelectric systems of the Andean countries.


To evaluate the repercussions of climate change on hydroelectric generation in the countries of the Andean subregion (Bolivia, Colombia, Ecuador, Peru and Venezuela) and the suitability of implementing some measures to adapt to this phenomenon.

Outstanding results

– In large areas of the Andean region, an increase in average precipitation is expected, which will alter hydroelectric production.

– In the easternmost part of the region, there would be reductions in rainfall, and therefore in hydroelectric potential.

– In some areas of the region (Eg: basin studied in Peru) climate change exacerbates seasonality, with higher rainfall in the wet season and less in the dry season, causing longer periods of drought.

– The intensity and frequency of extreme events such as floods and droughts will be increased. It also foresees a greater impact of climate change on plants that do not have seasonal storage capacity.

– Generalized increase in temperature throughout the region, although more moderate in coastal areas.

– Climatic variations in precipitation and temperature are more intense in the RCP 8.5 scenario than in RCP 4.5.

– Generally speaking, there is a greater long-term opportunity for hydroelectricity in the region.

– CC can also affect the rate of silt clogging in reservoirs and the wear of elements such as turbines.

– The greater hydroelectric potential due to the CC and the hydrological complementarity between the different basins, could facilitate the export of renewable energy from surplus regions in wet periods.

– Simulated adaptation measures in the pilot basins (reforestations, terraces, agroforestry, etc.) show a reduced effect on electricity generation, but significant for the control of basin erosion.
