Influence of El Niño Southern Oscillation on Global Hydropower Production

El Niño Southern Oscillation (ENSO) strongly influences the global climate system, manifesting in periodic droughts and floods across many regions of the world. Whist the impacts of ENSO on precipitation and runoff have been studied extensively, the effects on global hydropower production remain unclear. To assess these impacts, we simulate the operations and storage dynamics of about 1,600 hydropower dams—representing more than half of the world’s existing hydropower capacity. Results show that approximately 35% of the world’s hydropower dams exhibit reliable anomalies in power production in at least one of the two ENSO phases of El Niño and La Niña. When aggregated at the global level, positive and negative anomalies effectively cancel each other out, resulting in a weak and statistically insignificant global-scale anomaly in hydropower production for both ENSO phases. Negative anomalies in inflows resulting from ENSO are often weakened in the hydropower production time series, indicating the role of long-memory reservoirs in smoothing the effects of climate variability.
