Joint power plant Inn, Martina (GR)

The joint Inn power plant (GKI) on the Upper Inn in the Swiss-Austrian border region is the largest new run-of-river power plant to be built in the Alpine region for many years. An approximately 15 m high weir is being built below Martina to collect the water. The water will be fed through an underground pressure tunnel to the power plant in Prutz (A), where electricity will be generated. Sub-projects on Swiss soil include the reservoir with flood protection dam at Martina and the weir system with fish ladders and fish ladders
