Historical view

The oldest mentions of the mill in Wolica come from the mid-nineteenth century. At that time, the mill was powered by two wooden wheels, 4 m in diameter. At the turn of the 19th and 20th centuries, the wooden building was rebuilt and a brick structure was erected in its place, the remains of which can still be seen today. After the reconstruction, the mill retained its previous function, but the grain milling rollers were not driven by two but one wheel, the diameter of which was 8 meters.

In 1932, a Francis turbine was installed in the mill, produced by the St. Weight S.A., with a power of 32 HP (horsepower). It was placed in a turbine cage located in an added building.

After the flood in 2001, the mill was transformed into a hydroelectric power plant and since then, after two modernizations, this is how it works.
