Afternoon panel discussions

Discussion topic 1: Potential for FPV-DR

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.

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

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

Discussion topic 2:  Design issues / Risk analysis and management

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 to be announced)

DAY 2 – Case studies, hybridization options and E&S issues

Morning presentations

• Perspective from UEGCL – M. Mukulu, UEGCL, Uganda

• Status in Burkina Faso and neighbouring countries  – A. Nombre, IFEC, Burkina Faso

• Update on 2 FPVs in Indonesia – A. Firman, Vice-Chairman, INACOLD, Indonesia

• Floating solar powerplants in Vietnam – M. Ho Ta Kanh, Consultant, Vietnam

• Nam Theun 2  (Laos) and Lazer (France) projects – A. Rousselin, EDF-CIH, France

• Alqueva and Alto Rabago, Portugal – F. Guerra, EDP, Portugal

• Solar, hydro and pumping: a mix for tomorrow – F. Lempérière, HydroCoop, France

(Additional papers to be invited, from India, Korea, Ghana, Brazil and USA)

Afternoon panel discussions

Discussion topic 3: Coupling: solar-hydro hybridization

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?

Discussion topic 4: E&S issues

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:

• 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?

Impacts on fisheries:

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

Life cycle analysis:

• 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?
