Weather and climate services for hydropower management
Résumé
Predictions in hydroelectricity systems aim to help managers and stakeholders to guarantee people safety and dam security (in the case of reservoir-based systems) against extreme events, as well as to optimize energy production and the economic value of water resources. In a society moving towards a low-carbon economy, hydropower has the advantage of being a renewable source of energy that can be stored and reallocated in space and time and thus better handle the natural variability of hydrometeorological hazards and the occurrence of extreme events and/or peak demands. Hydropower
water reservoirs may also be storage facilities to be operated in a sharing environment: not only for energy production purposes, but also for domestic and agriculture water supply, environment protection, tourism, flood protection, etc. Improved predictability of hydrometeorological events (reservoir inflows and extremes), and improved risk assessment techniques are crucial to the operational decisions taken at different time and space scales in hydropower operational systems.
Examples in France, Italy, Spain, and Sweden illustrate the broad spectrum of potential collaborations between weather and climate services providers, water resources researchers and European energy production companies. In this short communication, we also highlight the challenges and open
opportunities that may further strengthen the usefulness of climate and weather inputs for the hydropower sector.
