The power plant is located on the Brda Młyńska Canal at 2A Mennica Street in the Old Town area of Bydgoszcz on Młyńska Island. The small hydroelectric power plant was established in December 1998 as a result of the modernization of an existing hydroelectric plant built during World War I. The power plant was equipped with two vertically mounted “Francis” water turbines with a gear transmission featuring wooden gears. One turbine was used to power the mill and sausage-making equipment, while the other drove a generator that supplied power to the mill’s own equipment. In 1970, Hydroprojekt conducted a technical assessment and proposed decommissioning the power plant by encasing it in concrete and backfilling the canal.

28 years later, in 1998, the technical condition was no better. The synchronous generator on turbine No. 1 was replaced with a new asynchronous generator. Later, an identical generator was installed on turbine No. 2. The electrical switchgear was replaced with a modern system. This took place in early 1999.

The next stage involved modernizing the intake screens, which were over twenty meters long, and preparing the water supply pipe for the planned turbine No. 3. Installation of the third turbine, a Kaplan turbine with 4 blades, type S. Generator power: 55 kW. This took place at the end of 1999. The challenge was that the turbine had to be “floated” into place, as it could not be installed using a crane.

In early 2000, turbines 1 and 2 underwent a major overhaul. Wooden teeth were replaced with belt drives. Two new asynchronous generators, each with a power output of 125 kW and a speed of 375 rpm, were also installed. That same year, the third turbine was replaced with a 200-kW Kaplan turbine supplied by MAVEL. The generators from turbines 1 and 2 were repurposed for this turbine. (2x110 kW) In 2001, a fourth 55-kW Kaplan turbine was installed, and repairs were carried out on the gate valves and roofs. Renovation of the building facades began.

In 2004, a fifth 200-kW Kaplan turbine was installed, and a water supply pipeline was constructed.

All of the electricity generated at MEW is supplied to the grid of the Bydgoszcz Power Company. The production of 600 kW of green energy reduces harmful carbon dioxide emissions into the atmosphere by 5,427 kg per year compared to energy produced from coal in conventional power plants.
