• Chair:  E. Quaranta, European Commission, DG Joint Research Centre, Italy

The theoretical potential is huge. Speakers will discuss the real potential available and realistic to develop, and variations in the potential in different parts of the world.

• Introductory talk by the Chair: The role of floating PV in the retrofitting of existing hydro plants and evaporation reduction

• What is the current FPV-DR situation: potential, projects, challenges, …?

• FPV on reservoirs in high alpine regions

• How does FPV-DR compare with classical PV, from a developer’s point of view (CAPEX, OPEX, efficiency, …)?

• Panellists: O. Tricca, European Investment Bank, Luxembourg; F. Boshell, IRENA; A. Rousselin, EDF; A. Kahl, Institute for Snow and  Avalanche Research, Switzerland

Half hour break for networking with exhibitors and participants (15.30-16.00 hrs)

SESSION 3 (16.00 – 17.30 hrs): Panel discussion

Topic 2:  Design issues / Risk analysis and management

• Chair:  F.  Gorintin, Innosea, France

Extreme events (waves, wind and others) will be discussed in relation to floating solar panels. Large dam reservoirs can generate high waves, induced by strong wind events. This has caused already caused failures of floating solar panels (for example on the Yamakura reservoir).

• How can waves and strong winds be robustly modelled?

• Options to withstand high waves (1.5+m) and very strong winds (120+ km/h)?

• Have other extreme events been considered at existing projects?

• Risk analysis / Risk management: are FPV an additional potential failure mode to be considered? How are the specific risks assessed and how are they managed?

• Moorings: Large dam reservoirs can be very deep, and may have large level variations. What are the best mooring options in these conditions?

• Panellists: C. Gery, Seaflex AB, Sweden; A. Argyros, DNV GL Energy, Norway; O. Ilan, Makor Energy, Israel; D. Barbosa da Silva, BASE Energia Sustentável, Brazil

Meetings, receptions, demonstrations by exhibitors in the Networking Lounge (17.30 – 18.30 hrs)

SESSION 5 (13.30 – 15.00 hrs): Panel discussion

Topic 3:  Coupling: solar-hydro hybridization

• Chair: Dr R. Bucher, Tractebel Engie, Germany

Options and benefits: Several kinds of hybrid project can be contemplated, with very varied options for hybridization, and hence very different benefits, either for energy production or water resources preservation.

• What are the options for hybridization, and what are the possible benefits?

• Which case studies serve as the most significant examples?

• Panellists: T. Reindl, Solar Energy Research Institute of Singapore (SERIS); S. Sterl, IRENA, Germany; L. Canale, Scatec; Norway; I. Meyer, Mott MacDonald, UK;  Dr N. Lee, National Renewable Energy Laboratory (NREL), USA

Half hour break for networking with exhibiting companies and other participants (15.00 – 15.30 hrs)

SESSION 6 (15.30 – 17.00 hrs): Panel discussion

Topic 4:  E&S issues

• Chair: F. Ribeiro Telles, EDP – Sustainability and Environment, Portugal

The panellists will debate the main E&S challenges related to FPV on dam reservoirs, and how to design a FPV powerplant that minimizes these issues and optimizes E&S benefits. Solar PV has an impact on the physical, chemical and biological cycles in the reservoir, so the first discussion topic will be impacts on biodiversity, and the second main topic will be studies on life cycle analysis.

• Can more be done to delineate these impacts precisely?

• Do we have data from projects where large parts of a water body have been covered?

• Do we have data, where impact on fisheries has been appraised, or measured?

• How life cycle analysis (LCA) of a project might help when comparing options and projects

• Are data available from past projects, where LCA of FPV has been derived?

• Panellists: S. Cromratie Clemons, University of North Carolina, USA;  S. Howard, Mott MacDonald, UK;   B. Hofs, Evides, Netherlands; Dr J. Stave, Multiconsult, Norway; A. Grenier, EDF, France

Updates will be published regularly on our website, where registration is now open, and full details are given of attendance fees.
