Installation Highlight

Gungin Oze Katashina Power Station
For our first project, new construction at Gungin Oze Katashina Power Station, we supplied European-made turbines and generators and handled everything from the design and manufacture of the control systems and various ancillary facilities to their delivery, installation, and commissioning.
This was also the client’s first project involving the installation of an overseas-manufactured hydroelectric turbine, and therefore we have provided support from equipment selection through to the start of operations. By implementing an optimal system configuration tailored to the local topography and water flow, we are contributing to the client’s goal of carbon-neutral initiatives that promote coexistence with the local community.
Furthermore, in collaboration with the customer’s Value Enhancement Project, we incorporated a viewing window into the water turbine casing so that the impeller inside the turbine can be seen rotating under the force of the water. This design allows the turbine to be used in educational programs in coordination with local boards of education and schools, visually demonstrating the mechanics of hydroelectric power generation and adding new value to the facilities.
