Jochenstein also serves as a border crossing between Upper Austria and Bavaria, and is therefore open to cyclists and pedestrians from 6.00 am to 10.00 pm. The power plant, which has a bottleneck capacity of 132 MW, is the most powerful power plant of the “border power plants” group and capable of supplying around 221,000 households with electricity generated entirely from hydropower.

Turbines and generators: Five Kaplan turbines with vertical shaft generate a total output of 132,000 kW with the five three-phase synchronous generators in the shield design. The maximum intake capacity of all turbines is 2,050 m³/sec. Beyond this volume, water must be discharged via the weir system.
Weir system: The weir gates are designed as riveted double hook gates with electromechanical winches and gall chains. The power plant belongs to the “border power plants” group, which is noted for its geographical location on the rivers Inn and Danube, where they form the border between Austria and Bavaria.
