On 17–18 September 2025, the SHF HydroES Conference in Grenoble, France, brought together experts and stakeholders to advance knowledge on hydropower and environmental sustainability. The event provided an important platform for presenting the latest work developed within the ETIP HYDROPOWER Working Groups.

Denis Aelbrecht, Chair of the Governing Board, opened the session with an introduction to ETIP HYDROPOWER and later offered closing reflections. Maryse François presented the White Paper on Flexibility, inviting participants to continue the conversation during the upcoming webinar scheduled for 8 October 2025. Agnès Barillier followed with a presentation of the main messages from the White Paper on E-flows and Biodiversity, while Benjamin Graff shared preliminary insights from the forthcoming White Paper on Climate Change, which will soon be made publicly available.

The two-day conference concluded with a series of technical visits that offered participants hands-on insights into hydropower innovation and sustainability. At the EDF Cheylas pumped storage plant, participants explored sediment management solutions developed by Watertracks through the Nessie technology. At the SuperGrid Institute, the group visited the TM1 Scaled Model test platform (IEC 60193) and the HydroPHIL transient platform, and took part in discussions on hybridisation with batteries, variable speed solutions and the economic value of hydropower in electricity markets. The programme also included a visit to the ARTELAB Modelling Laboratory, managed by Artelia.
