Hydropower is an important source of renewable energy for electrical production in Europe and throughout the world. Being flexible and allowing energy storage, it also facilitates the development of intermittent energy in electricity systems.
The major challenge of hydropower is to reconcile its development with environmental and societal needs. This means maintaining a balance between the different ways water is used and the preservation of biodiversity, while contributing to sustainable river development. Reliable and efficient hydropower facilities that protect the environment can improve hydropower performance, as well as its environmental acceptability.
The International Hydropower Association (IHA) has, for example, developed a “hydropower sustainability assessment protocol” that has been implemented in several countries. The environment is at the center of all new hydropower projects and the rehabilitation of existing facilities.
Nearly fifteen years after the launch of the European Water Framework Directive, and at a time when climate change and the energy transition are the focus of debate, this symposium aims to make an assessment of how environmental aspects are being accounted for in projects for the development or renovation of hydropower installations in various countries.
Communications will concern both “large” and “small” hydraulics and multipurpose facilities.
They will present scientific and technological advances, as well as case studies that enable highlighting best practices and comparing solutions implemented in different countries.
Opening Invited Lecture: Philippe Dupont (ONEMA - F)
The symposium will focus on three topics:
Topic 1: Socio-environmental integration of hydropower facilities
Atle Harby (SINTEF - Norway)
- Tools and methods for overall evaluation of socio-environmental factors
- Balancing biodiversity, hydropower and the other uses of water
- Integrating other types of renewable energy
- Impact of climate change on water resources and repercussions on hydropower
- Implementation of the ARC (Avoid, Reduce and Compensate) sequence and feedback on the AIH
- Regulatory frameworks, public policy and stakeholders involvement
Topic 2: Ecological and sedimentary continuity
Geoff Petts (Vice-Chancelor - Westminister University - UK)
- Sediment, alluvial margins and flushing management
- Ecological engineering and means of action
- Environmental restoration
- Repercussion of facilities on biodiversity
- Impact of ecological flow and hydropeaking on ecosystems
Topic 3: Technological innovation for low-impact facilities
Farid Mazzouji (Alstom Hydro Power GE- f)
- Oil free machines (water lubrication, biodegradable oil, etc.)
- Fish-friendly, aerating turbines
- Turbining of ecological flow and low flow rate (waste water, drinking water, etc.)
- Fish passes and technological solutions for protecting fish
This symposium is meant for all those concerned by environmental issues, including scientists and researchers, contracting authorities and hydropower facility operators, industries, consulting companies, administrators and territorial groups.
Posters will be presented in the plenary sessions and will round out the oral communications.
The symposium language is English.
