Hydropower plants are an important renewable energy source as they may allow a quick response to short-term changes in the electricity market. Due to the favorable topographic and hydrologic conditions in Austria, storage and pump-storage hydropower plants constitute 33% of the total national installed energy generation capacity. However, their operation mode – the release of pulsed flow – affects downstream river ecosystems and has been identified as a critical threat to fish populations. To achieve environmental objectives (e.g., those of the EU Water Framework Directive), it is necessary to select appropriate measures to mitigate adverse ecological hydropeaking effects. Here, I also give an overview of the current status and outlook of hydropeaking research and development in Austria, summarize best management recommendations regarding fish populations, and discuss mitigation scenarios related to their impact on business and national economy by presenting a novel integrative approach.
