What do others say?
• IEA/ECF – ‘limited increase’
• EREC - 38% increase
• PWC/RWE – 30-100% increase

ECRINS database
• Selected catchment highlighted.
• Nodes with elevation & mean flow
• Dams
Example of ECRINS extract from PyreneesExample of ECRINS extract from Pyrenees
Example of catchment data extractExample of catchment data extract
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 – 4,000Spain 1,000 – 1,500
……assumptions (technical)• 20 year life span• 10% discount rate• Discounted cash flow analysis for each site
Assumptions (environmental potential)
• Q0=33%• Reduces potential by 40%
Limitations• Proximity to grid • Mean flow used• Costs based on a range (site-specific)

Improvements
• Link road/grid databases with ECRINS• Use multiple years for better mean flow• Refine capital and mitigation costs• Verify with real examples

Innovation
Innovation is a change in the thought process for doing something
It may refer to an incremental emergent or radical and revolutionary changes in thinking, products, processes, or organisations.

Conclusions
•Restricted technical potential
•Focus on adapting business model
•Article 4.7 is sacrosanct
