At July 2015, installation works were finished in Miedzna hydroelectric power plant (Poland).

In this interesting site two propeller turbines were installed with rotor diameter 320 mm and 480 mm. Both turbines are feed by one pipe line, which is taking the water from the bottom of Miedzna lake. The building is located on right bank above outlet from the dam. The head is 5.8 m ? because of installation of simple propeller turbines it was possible to exploit the site in economic way.
