    • Criteria for a sustainable HydroPower development in TyrolDevelopment and Application fora GIS based Hydropower Potential DeterminationProject Final Meeting of SHARE - Sustainable Hydropower in Alpine River Ecosystems24th of May 2012 in Aosta, Italy W. Widmann
    • Criteria for a sustainable HP development in TyrolContent  Background  Goals  Development of Criteria  Process of Development  Example Criteria  Application in a GIS based HP Potential Determination  GIS Modell  HP Potential Determination  Results SHARE – Project Final Meeting
    • Criteria for a sustainable HP development in TyrolBackground Changed boundary conditions for Hydropower development… … 40 and more years ago  monopoly of utilities in energy sector  „Bevorzugter Wasserbau“ – priority rights for HPPs  Environmental protection had small weight in concessions  High value of energy sector interests …today  High sensitivity for protection of environment  Liberalized energy sector  High value of environment sector interests SHARE – Project Final Meeting
    • Criteria for a sustainable HP development in TyrolBackground Need for additional production of electricity by HPPs  increasing pressure  Austria imports since 2001 more electricity than it exports  Share of fossile electricity production is increasing 35.000 30.000 Wärmekraftwerke Plant Termal Power 25.000 Export-Import-Bilanz Export-Import Balance Net Import Tangent Nettoimporttangente 20.000 15.000 10.000 5.000 0 1950 1955 1960 1965 1970 1975 1980 1985 1990 1995 2000 2005 -5.000 -10.000 Source: e-control SHARE – Project Final Meeting
    • Criteria for a sustainable HP development in TyrolBackground Need for additional production of electricity by HPPs  increasing pressure  Austria imports since 2001 more electricity than it exports  Share of fossile electricity production is increasing  Austria cannot achieve Kyoto protocol goals  Energy Strategy Austria 2020 demands more HPPs  Energy of Tyrol demands more HPPs  Directive for Renewable Energy  Roadmap Energy 2050 Tyrol… …has 40 to 50% of Austria‘s remaining Hydropower Potential …planned projects do not proceed as necessary  criteria for sustainable HP-development are required SHARE – Project Final Meeting
    • Criteria for a sustainable HP development in TyrolGoals of Catalogue of Criteria CRITERIA ANSWER the questions … 1. WHERE to build HPPs = strategic level (regional programs, framwork plans, etc): Identification of (sectors of) water bodys suitable for HPP development 2. HOW to build HPPs = operative level (assessment of projects):  A balanced weighing of conflicting interests  equitable consideration of all dimensions of a HPP  objective assessment of projects  Considering energy sector, water basin managment, limnology, regional planning and environmental aspects SHARE – Project Final Meeting
    • Criteria for a sustainable HP development in TyrolGoals Criteria give NO ANSWER to questions:  IF HPPs are required  This would require comparison with other energy production options:  CO2 balance,  Energy balance  Electricity Network considerations, ….  HOW MANY HPPs are required  Demand prognosis considering  Energy saving  Reduction on dependance on fossile and nuclear production  Peakdemand …… SHARE – Project Final Meeting
