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
