Historical overview

The SHP, picturesquely located on the edge of the Carpathian Foothills, was built at the same time as the accompanying rubber dam, i.e. in 2000. It is located on the right bank of the Wisłoka River. A river damming with a span of approx. 100 m was constructed south-east of Pilzno in connection with the reclamation of the aggregate post-mining area. The flooding of the area between Strzegocice and Mokrzec towns led to the creation of a water reservoir of over 140 ha. The investment landscape is complemented by an impressive over 400-metre fish ladder for aquatic fauna. Repowering of the power plant carried out by IOZE hydro was focused on optimising the use of the hydroelectric potential of this location.

Parameters

Diameter 1,430 mm
Head of 4.6 m
Power 900 kVA

Technologies used

  • Three vertical Kaplan turbines and PMG generators

Thanks to the use of synchronous generators with permanent magnets (produced on special order), which cooperate with the turbines without the use of a gearbox, we have not only achieved a higher efficiency of the entire system, but also a noticeable improvement in the operating culture of the equipment. It is now extremely quiet inside the machine room, even when operating at full power. The SHP is also prepared to provide other system services in addition to generation. The control system can cooperate with an energy trading company by directly and automatically adapting the facility's operation to the current energy market conditions.
