Climate change impacts on hydropower in the Swiss and Italian Alps

Viene fornita una stima dell’impatto atteso del Cambiamenti Climatici (CC) sulla gestione futura degli impianti idroelettrici nella regione alpina attraverso l’analisi comparata dei risultati relativi a tre casi studio.

This paper provides a synthesis and comparison of methodologies and re-sults obtained in several studies devoted to the impact of climate change on hydropower. By putting into perspective various case studies, we provide a broader context and improved understanding of climatic changes on energy production and underlines the strengths and weaknesses of the approaches used as far as technical, physical and economical aspects are concerned. Although the catchments under investigation are located close to each other in geographic terms (Swiss and Italian Alps), they represent a wide variety of situations which may be affected by very differing evolutions, for instance in terms of annual runoff, in the future. In this study, we also differentiate between run-of-river, storage and pumping-storage power plants. By integrating and comparing various analyses carried out in the framework of the EU-FP7 ACQWA project, this paper also discusses the complexity as well as current and future issues of hydropower management in the wider Alpine region.
