UNIFYING THE VOICES OF HYDROPOWER

ETIP Hydropower Secretariat Holds Annual Workshop in the Alps and Visits Jotty Hydropower Plant

From October 7th to 9th, the ETIP Hydropower Secretariat held its annual meeting in the French Alps. The sessions aimed to discuss actions that highlight the importance of sustainable energy solutions and reinforce the role of hydropower in the energy transition. Members exchanged insights in a professional environment, focusing on the technical achievements and future direction of the project.

During the meeting, ETIP members explored the next steps for the project, reviewed work packages, addressed challenges and opportunities for a financially sustainable ETIP, and define the architecture of the 2025 Hydropower Day. This annual event is scheduled to take place in Brussels on Tuesday, April 8, 2025. Save the date! 

The 2025 Hydro Day will focus on hydropower's contribution to energy transition, with three sessions planned:

  • Session 1: The value of hydropower in providing flexibility and energy storage in a safe energy transition.
  • Session 2: Hydropower and environmental partnerships.
  • Session 3: Hydropower and climate change: challenges and opportunities for mitigation.

The meeting not only offered the consortium an opportunity to convene, exchange ideas, and discuss the latest developments in hydropower, but also included a site visit to the historic Bioge-Jotty hydropower plant.

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.

ETIP HYDROPOWER second webinar in EU hydropower R&I projects

On 18 September 2024, ETIP HYDROPOWER hosted the "Boosting Hydropower II: Best Practices for Research" webinar series, which provided updates on current developments in hydropower technology. The event, held from 1:30 PM to 3:00 PM CET, featured presentations on three EU research projects aimed at improving hydropower’s role in Europe’s energy system, with hundred attendees. 

Mauro Carolli from SINTEF Energy Research presented ReHydro, a project that focuses on the refurbishment and modernization of European hydropower systems. It aims to strengthen the role of hydropower in future power grids while addressing sustainability and climate change challenges.

Staffan Lundström from Luleå University of Technology, Sweden, introduced Store2Hydro, a four-year project funded by the European Commission’s Horizon Europe programme. The project explores the integration of reversible pump turbine technology into existing hydropower plants to improve electricity storage capacity.

Clement Van Straaten from ASKEUL presented the RENEWAT project, which focuses on repurposing water mills for renewable energy production. The project involves partners from six EU countries and aims to share knowledge and promote renewable energy initiatives in local communities.

The session also included contributions from Emanuele Quaranta of the European Commission’s Joint Research Centre (JRC) and Anton Schleiss from the International Commission on Large Dams (ICOLD), who highlighted ETIP HYDROPOWER’s role in representing the hydropower sector.

This webinar provided an overview of ongoing research efforts to enhance hydropower’s efficiency, sustainability, and integration into Europe’s energy systems.

Stay tuned for the next webinar, which will take place on the 6th of December, presenting three new EU-funded projects in hydropower.

ETIP HYDROPOWER Leadership Participates in ICOLD Annual Meeting and Symposium in New Delhi

Last week, members of the ETIP HYDROPOWER Secretariat and Governing Board played a key role at the ICOLD Annual Meeting and Symposium held in New Delhi, India. The event brought together global experts to discuss advancements in dam engineering, climate change, and hydropower.

Representing ETIP HYDROPOWER were:

  • Anton Schleiss, Honorary President of ICOLD and Chairman of the Technical Committee on Hydraulics for Dams.
  • Denis Aelbrecht, outgoing Chairman of the Technical Committee on Climate Change.
  • Antonella Frigerio, newly elected Chair of the Technical Committee on Computational Aspects of Analysis and Design of Dams.

During the event, participants discussed the preparation of a World Declaration on the role of dams and reservoirs in supporting the energy transition and adaptation to climate change. This important declaration will be developed in collaboration with other organizations to highlight the significance of hydropower infrastructure in the global shift to renewable energy and climate resilience.

The involvement of ETIP HYDROPOWER in these discussions underscores the organization's commitment to promoting sustainable hydropower solutions and addressing the challenges posed by climate change.

 

Anton Schleiss at the Global Hydropower Day Webinar

During the Global Hydropower Day, Professor Anton Schleiss, Coordinator of ETIP HYDROPOWER, participated in a webinar organised by the International Hydropower Association (IHA) that discussed the progress and challenges within the hydropower sector. The event brought together experts to share insights on sustainability, operational challenges, and workforce development in hydropower projects.

Professor Schleiss presented ETIP HYDROPOWER’s work, focusing on its role in fostering innovation to meet Europe’s hydropower needs and its contribution to the sector's long-term sustainability goals, addressing how the project aim to support the doubling of hydropower capacity by 2050 to meet global net-zero objectives.

The webinar also featured discussions on overcoming technical and environmental challenges in hydropower development. Case studies from various regions provided examples of obstacles hydropower projects have encountered, alongside lessons learned that are shaping future development strategies.
