The Słupia, the Radunia, and the Wierzyca are rivers whose location and energy of water flow was taken advantage of to build hydroelectric power plants. Many of them are still operating and can be visited. The oldest such power plant in Europe, Struga, or the Radunia’s highest-situated plant in Bielkowo, are only a few of the facilities well worth seeing. The principles of physics, chemistry, and mathematics are contained in machines and post-industrial sites, and presented at thematic exhibitions, such as in the Hewelianum Centre.
The Krzynia hydroelectric power plant on the Słupia
One of the most beautifully-located hydroelectric power plants on the Słupia, Krzynia, located among the woods and moraine hills, is a frequent destination of hiking trips.
Built between 1925 and 1926, the power plant constitutes the lowest barrage of the river. It is said to be the favourite place of leisure for Słupsk's residents. The storage reservoir that was created here as a result of damming the river covers an area of 78 ha and has a capacity of 1.38 million cubic metres. Due to the fact that the power station is the last of the hydrotechnical monuments before the capital of the Słupsk Land, the Town of Słupsk, a flow below 3.4 cubic metres per second is recommended. The power of the Krzynia hydroelectric plant is 860 KW.
