3 Impact of Water Framework Directive Consequences of the WFD implementation on the Hydropower- System and Projects Hydro-peaking Reduction of peaking ratio leads to Loss of flexibility in power generation Loss of ancillary services (scheduling, dispatch..) Loss of security of supply Lack of knowledge concerning relevant measures and their environmental and economical consequences No-deterioration principle Strong influence on new hydropower projects, approval only on the basis of exemptions (overriding public interest, no better environmental option, all possible measures to minimize negative impact) The No-deterioration principle does not prevent new projects but it has to be considered in the planning process. Secure the important role of hydropower in a future sustainable Europe by keeping generation losses low VGB PowerTech e.v., PAGE 7 4 Hydropower Projects - Continuous Strategic Planning Process Continuous strategic planning process History and Development River management in Europe Long time experiences in project- and site-planning (first hydropower plant 1880) All existent and new projects are results of extensive continuous strategic planning processes, considering all relevant aspects (technical, ecological, economical, infrastructural, administrative, acceptance etc) Result: Only a part of the Hydropower potential is used for electricity generation Hydropower potential theoretic potential 2) ~ 1,600 TWh (100%) - possible potential ~ 630 TWh (40%) remaining potential ~ 970 TWh (60%) theoretic 2) ~ 1,600TWh possible 3) ~ 630TWh today used 1) ~ 350TWh VGB PowerTech e.v., PAGE 8 60 % of the hydropower potential in EU 27 will keep untouched Sources: 1) Eurelectric Power Statistics 2) University Kassel 3) Eurelectric Power Statistics and Hydro in Europe 4
