2010 - Environmental impacts of hydropower

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

  6. 6. • Policy• Resource/constraints• Environmental factors Creative Commons – Joshua Cogliati
  7. 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. 8. EEA study• Technical potential• Environmental potential• Carried out by AEA Creative Commons – Felix Andrews
  9. 9. ECRINS database
  10. 10. Example of ECRINS extract from Pyrenees • Selected catchment highlighted. • Nodes with elevation & mean flow • Dams
  11. 11. Example of catchment data extract
  12. 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. 13. ……assumptions (technical)• 20 year life span• 10% discount rate• Discounted cash flow analysis for each site
  14. 14. Assumptions (environmental potential)• Q0=33%• Reduces potential by 40%
  15. 15. Limitations • Proximity to grid • Mean flow used • Costs based on a range (site-specific)Creative Commons – VargaA
  16. 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. 17. • Policy• Resource/constraints• Environmental factors Creative Commons – Tom Bishop
  18. 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. 19. Comparative effectshttp://circa.europa.eu/Public/irc/env/biodiversity_climate/library?l=/contract_biodiversity/report_task_4pdf/_EN_1.0_&a=d
  20. 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. 22. Conclusions• Restricted technical potential• Focus on adapting business model• Article 4.7 is sacrosanct Creative Commons – Richard Haworth
