Historical overview
The water-mill was built between 1900 and 1901 by the von Kameke family, local landowners. A few years later – in December 1949 – the watermill was taken over by the People's Republic of Poland Government under the Ruling of the Minister of Internal Trade1 and was managed for the next several decades by the Polish Grain Plant in Stoisław. Over the years, the watermill's drive was modified to include a hydroelectric system, with the facility operating two Francis turbines. In 2001, the watermill ended up with the current owner. The Niedalino SHP is part of a cascade of hydropower plants that also includes the Energa Group's Niedalino Hydropower Plant built in 1912 and the Rosnowo Hydropower Plant built in 1922 on the Rosnowski Canal.
Parameters
Technologies used
- Two vertical Kaplan turbines, each with the capacity of 75 kW
- 4 modern control cabinets
The Niedalino SHP has seen a tremendous technological leap as a result of its modernisation. We replaced the purely manual power plant controls, utilising pre-war German-made equipment, with modern and intuitive equipment. We supplied the Niedalino SHP with two complete hydrosets with asynchronous generators. Due to the type of generators used, the system was fitted with a reactive power controller. Each of the hydrosets can operate either autonomously or controlled by a master controller. Safety control system settings can be changed, and advanced diagnostics performed, separately for each hydroset. The facility has been equipped with a remote access solution in the form of a SCADA visualisation system. It allows us to generate reports from different periods. This is an indispensable source of knowledge about the facility's operation, which enables such things as timely prevention of serious failures and optimising device operation.
Investment planning:
- Evaluation of available hydropower potential
- Conceptual proposal for the utilisation of the potential
- Financial and technical advisory
Consulting and Design:
- Advisory to maximise the gain on sale of generated energy
- Developing a complete set of design documentation
- Obtaining a certificate from the Energy Regulatory Office (URE) regarding the guaranteed energy price
Execution of construction works as a general contractor:
- Dismantling the two existing hydrosets and installing two new ones
- Implementing a new control and automation system
- Renovating the concrete surfaces of the inflow chamber and part of the machine room floor
