  • 1. Hydro The view from the EEA Hidroenergia Lausanne, 17th June 2010 Dr. David Clubb Renewable Energy Project Managerwww.eea.europa.eu
  • 2. • Policy• Resource/constraints• Environmental factors

  • 7. What do others say?• IEA/ECF – ‘limited increase’• EREC - 38% increase• PWC/RWE – 30- 100% increasewww.roadmap2050.eu/Volume1_fullreport_PressPack.pdfwww.erec.org/fileadmin/erec_docs/Documents/Publications/ReThinking2050_full%20version_final.pdfwww.pwc.co.uk/pdf/100_percent_renewable_electricity.pdf
  • 8. EEA study• Technical potential• Environmental potential• Carried out by AEA Creative Commons – Felix Andrews
  • 9. ECRINS database
  • 10. Example of ECRINS extract from Pyrenees • Selected catchment highlighted. • Nodes with elevation & mean flow • Dams
  • 11. Example of catchment data extract
  • 12. Assumptions (technical potential)• Qmean and head can be extracted• Water to wire efficiency 70%• Q0 = 75%; CF 50%• O&M 1-2% (ESHA)• Capital costs (ESHA): (€/kW Installed) France 1,850 – 4,000 Spain 1,000 – 1,500
  • 13. ……assumptions (technical)• 20 year life span• 10% discount rate• Discounted cash flow analysis for each site
  • 14. Assumptions (environmental potential)• Q0=33%• Reduces potential by 40%
  • 15. Limitations • Proximity to grid • Mean flow used • Costs based on a range (site-specific)Creative Commons – VargaA
  • 16. Improvements • Link road/grid databases with ECRINS • Use multiple years for better mean flow • Refine capital and mitigation costs • Verify with real examplesCreative Commons – Dale Klamuella
  • 17. • Policy• Resource/constraints• Environmental factors Creative Commons – Tom Bishop
  • 18. Environmental factors•Hydrological character•Connectivity within system•Solid material and morphology•Landscape and biotopes•Biocoenoses Creative Commons – Richard Haworthhttp://homepages.eawag.ch/~wehrli/papers/Bratrich_GreenHydro_RiverRes_04.pdf
  • 19. Comparative effectshttp://circa.europa.eu/Public/irc/env/biodiversity_climate/library?l=/contract_biodiversity/report_task_4pdf/_EN_1.0_&a=d
  • 20. InnovationInnovation is a change in the thoughtprocess for doing somethingIt may refer to an incremental emergent orradical and revolutionary changes inthinking, products, processes, ororganisations.

  • 22. Conclusions• Restricted technical potential• Focus on adapting business model• Article 4.7 is sacrosanct Creative Commons – Richard Haworth
