The core business of JNC Group as a leading chemicals company includes research & development, manufacturing and selling of liquid crystal materials and organic EL materials.  At the same time, we also regard the environment and energy groups as an important business domain.  We own hydraulic power stations (total maximum output of 94,600 kW) in 13 places and photovoltaic power stations (total maximum output of 16,000 kW) in 4 places in Japan for developing the power generation business using renewable energy.


All of our hydraulic power stations adopt a "run-of-river type" system.  In this system, foreign matters are removed from river water, the water is guided via a channel into a head tank and dropped through a penstock to turn a water turbine for generating electricity.  Since the run-of-river type hydraulic power generation does not require a large-scale dam, it is friendly to the environment, has low carbon dioxide emission and provides precious, purely domestically produced energy.


Among the power stations undergoing large-scale renovation since 2013, the Kawabegawa Second Power Station has started business service.  This is the fifth station undergoing large-scale renovation to start business service.  By renewing the water turbines and generators to high-efficiency equipment, the maximum output was increased by 700kW (about 9%) while keeping the approved water intake amount.  Our Corporation will take advantage of the power generation technologies cultivated so far to contribute to the society by supplying stable energy in future years with consideration for the environment.
