Small hydropower plant in Starogard

Small hydropower plant in Starogard

Wierzyca river

An active fish pass produces electricity

A fish pass can also produce electricity. The use of an Archimedes screw set, one of which transports fish upstream and the other one downstream, at the same time producing electricity is an innovative project that increases profitability of the investment and reduces the area of the required development. Thanks to the use of biological flow, we produce additional electricity from a renewable energy source without the adverse effect on the natural environment, while meeting the need for patency of the river.

Historical outline

The dam, on which the new small hydropower plant was installed, had been part of the technical infrastructure of the already defunct Starogardzkie Młyny, located several hundred metres downstream. 

The first mention of Młyny comes from the Teutonic period. At that time it was a facility with one water wheel located in the mill channel (the channel has been preserved up to now). However, the Starogard milling had a true renaissance much later, since only at the end of the 19th century and the beginning of the 20th century. At that time, the mill was expanded and the machine park modernised. In the 1920s a hydropower plant was built near Młyny.

The new small hydropower plant, equipped with an active fish pass, uses the biological damming flow.
