In Austria especially, an alpine land, where the water usage plays a major role because of the landscape, an exact analysis of the potential impact on the water framework directive concerning any use is important. Hydropower utilization has a huge influence: About 2/3 of Austria’s generated electric power is produced by the use of hydropower.
The aim of the current study is to find an ecological and economic optimum for the implementation of the water rights act that maintains the amount and quality of Austria’s primary energy sources and that also achieves the ecological goals stated in the water rights act. Simultaneously, sustainable use of the water resources should be guaranteed.
Based on scenario models, the bandwidth of possible consequences are to be highlighted that can be expected to support the energy economy in implementing certain measures to achieve a “good status”. Scenarios to be investigated include residual water allocation, surge limit and production of consistency. Hydroelectric plants of less than 10MW (small power plants). river powerplants over 10 MW and storage power plants are investigated separately.
