Hydropower facilities contribute to the reduction of the impacts of climate change, including extreme events, floods and droughts, which tend to be increasingly exacerbated. It is a local energy, which cannot be relocated, anchored in the territories and its facilities play a key role in the management of water resources for the satisfaction of multiple uses such as drinking water supply, irrigation, navigation, tourism, and in the management of the electricity system through its flexibility. It makes it possible to compensate for the intermittency of other renewable energies and to stabilise the network in the event of the fortuitous unavailability of other means of production.
 
Hydropower must therefore respond to multiple technical, societal and environmental issues and challenges. We must continually innovate to seek the best balance, to reconcile the various uses, to preserve aquatic environments and biodiversity, to adapt to climate change, and putting science, societal services and the living at the heart of the debates.
 
This symposium will be organized in 4 sessions and a technical visit:

 
1. Climate Change (Adaptation & Mitigation):
Pressures on water resources (melting glaciers, water temperature, drought, etc.), resilience strategies in face of extreme events, revision of engineering practices in project design, technological innovation, etc.

2. Energy Transition and Water Resource Management:
Energy efficiency, new hydrometeorological forecasting tools, optimization of water production and resources, flexibility and role of hydropower in the energy mix, reduction of the carbon footprint and role of hydropower (gravity development and WWTP) in the energy transition, marine energies, Reconciling uses and consultation, the solutions of the future, etc.

3. Digital Transformation and Modernization of Operations & Maintenance (O&M):
Evolution of O&M practices (remote control of development chains, plant 4.0, digital twins, etc.), role of new sensors, existing communication protocols for facility monitoring and environmental monitoring, new generation of modeling systems capable of integrating new data sources, artificial intelligence (IA) and Big Data: best practices for operational implementation and decision support.

4. Issues and Challenges of the Hydroelectric Fleet:
Ageing of structures and equipment, sediment management, fish farming continuity, new legal, environmental and social constraints, etc.

The visit was managed by EDF, with a presentation of the hydropower scheme by Sebastien Girardier (Photo 2). The Jotty Hydropower Plant (Photo 3), located in the Haute-Savoie region of France, sits in the scenic Vallée d’Aulps, just above the renowned Gorges du Pont du Diable. The plant, which is situated on the Dranse de Morzine river, plays a significant role in the local energy infrastructure. It generates 98 million kWh of electricity annually using four turbines, powered by the Lac du Jotty reservoir—a 1.1 hm³, 1.5 km-long body of water formed by the Jotty arch dam.

During the visit, Samuel Hubert from Hydrostadium provided an introduction to the Jotty dam, which was constructed between 1946 and 1949. The arch dam stands 22.5 meters high and spans 120 meters in length. In 2015, the dam faced a major challenge when a flood with a 200-year return period eroded the banks, uprooted trees, and caused a dense blockage in front of the dam’s bottom gate and gallery (Photo 4).

Restoring normal operations required several years of work and innovative solutions. A remote-controlled bulldozer was developed to remove the accumulated sediment, and divers were later brought in to complete the clearing of the conduit (Photo 5). This highlights the ongoing efforts required to maintain and preserve such critical infrastructure.
