摘要

The Alps create large heads and support the production of flexible energy. In Tyrol, the hydropower company TIWAG is operating 10 large (>10 MW) and 27 small (<10 MW) hydropower plants, with an installed capacity of about 1 650 MW and a mean annual production of 3 400 GWh/year. The water management framework plan for Western Tyrol proposes five large power plants, with a generation of 1 800 GWh/year of renewable energy, which enables to reach the WFD targets, because the concept includes hydropeaking mitigation by combining buffer reservoirs (impoundments), diversion hydropower plants and retention basins. Overall, a total volume of 1.8 million m³ and three hydropeaking diversion HPP along 70 km are foreseen. Some facilities are already implemented, others are under construction or in the permitting phase. We summarize our concept to reduce the effects of hydropeaking and exemplify this based on the existing hydropeaking diversion hydropower plant GKI as well as the 300 000 m³ Silz hydropeaking retention basin.
