The power plant Innstufe Imst Haiming is a planned medium pressure - Laufwasserkraftwerk am Inn in the Tyrolean Oberland in Austria . The project under the direction of TIWAG is in the environmental impact assessment (EIA).

history

In 2013, the project was submitted to the authorities for the preliminary assessment of environmental compatibility, which was successfully concluded. The actual environmental impact assessment began in 2015, which ended in the summer of 2016 with an improvement order. A suggestion for improvement was submitted in 2018. If construction began in 2020, the power plant would not be available until 2025 at the earliest.

When building the power plant, the water flow in the Imster Gorge , which is very popular with white water sports enthusiasts, must be taken into account . There is also resistance from the fruit and wine growers. They fear a change in the microclimate in the Haiming region due to fog that could emanate from the balancing tank of the power house . In addition, the headrace tunnel in the mountain could change the groundwater flow.

technology

The system is designed as a diversion power plant that uses the water from the existing Imst power plant above . No new weir system is therefore required in the Inn for the Imst-Haiming power plant . The 14.5 km long headrace line first leads along the right slope of the valley, changes the valley side at Karres and ends in the Haiming powerhouse, where the water is processed by turbines with a total output of 43.5 MW. The underwater reaches an equalization basin ^▼ , which allows it to flow evenly into the Inn. The power plant is expected to generate 270 GWh of electricity annually.
