Prędzieszyn Hydroelectric Power Plant – the last stage of the Radunia Cascade

The Radunia is a mountain river characterized by a rapid current and numerous rapids. In its upper course, it flows through the picturesque Kółko Raduńskie lakes, and in the lower section, below Żukowo, it has been transformed by humans into a system of six historic hydroelectric power plants. Towards Gdańsk, the river changes its character, becoming a typical lowland river, and flows into the Motława River in Krępiec, just an hour's drive from the Gdańsk Crane.

The Prędzieszyn Hydroelectric Power Plant, commissioned in 1937 as the last element of the Radunia Cascade, is a weir power plant closely connected with the power plant in Straszyn. Since it started operating, all the water discharged from Straszyn has flowed through the stage in Prędzieszyn, and then to the next stage in Kuźnice.

The construction of the power plant lasted less than a year, as it was carried out on dry land. After completion, the Radunia was directed to an artificially excavated channel feeding the turbines. The plant survived World War II without any interruptions in operation, and its key equipment – turbines, generators, and reducers – remain virtually unchanged to this day. The power plant reaches a capacity of 436 kW, with an average flow of 5.66 m³/s, making it an important element of the region's energy system.
