Notification of Large-Scale Renovation of Hydraulic Power Stations

JNC CORPORATION (CEO & President: Michio Morita, Chiyoda-ku, Tokyo) will execute the following renovation of existing hydraulic power stations developed in Kyushu.


The core business of JNC Group includes manufacturing, selling and developing liquid crystal materials and organic EL materials which contribute to the progress of a highly information-oriented society.  At the same time, we also regard the environment and energy groups as an important business domain for developing the hydraulic power generation business having run-of-river type hydraulic power stations (total maximum output of 93,200 kW) in 13 places in the Kyushu area, the business of manufacturing and selling members for lithium-ion secondary batteries, and so forth.  Furthermore, we have started the photovoltaic power generation business in Ichihara City, Chiba, and Moriyama City, Shiga since last year.


Although 50 to 100 years have passed since the hydraulic power stations of our Corporation have been installed, we have executed the renovation of obsolescent facilities based on the long-term planning to keep the power generation capacity.  From now on, we will sequentially renew the main facilities of the existing hydraulic power stations to high-efficiency generators or the like to increase the maximum output and the annual generation amount while keeping the approved water intake amount at the present level, and we will achieve an increase in hydraulic power generation and stable supply.

We will advance the renovation with sufficient consideration for the peripheral environment.


While the social demands for renewable energy increasingly grows, the importance of nature-friendly hydraulic power generation is being reassessed.  Our Corporation will take advantage of the power generation technologies cultivated so far to develop business activities with consideration for the natural environment and regional communities, and will contribute to the society by supplying stable clean energy in future years.
