JNC CORPORATION (CEO & President: Yasuyuki Gotoh, Chiyoda-ku, Tokyo) will execute the large-scale renovation of Naidaijingawa Power Station and Tsuru Power Station owned by JNC in Yamato-cho, Kamimashiki-gun, Kumamoto.

The core business of JNC Group includes manufacturing, selling and research & development of liquid crystal materials and organic EL materials which are essential to a highly information-oriented society. At the same time, we also regard the environment and energy groups as an important business domain and own run-of-river type hydraulic power stations (total maximum output of 93,700 kW) in 13 locations in the Kyushu area, and also work on photovoltaic power generation.

JNC has maintained the power generation capacity of our hydraulic power stations by renovating obsolescent facilities based on long-term planning. While the social demand for clean energy increasingly grows, our Company has sequentially promoted renovation of our hydraulic power stations in order to reinforce their power generation capacity and realize a stable supply of electric power.

Now, subsequent to the eight power stations already under renovation, we will also execute the large-scale renovation of Naidaijingawa Power Station and Tsuru Power Station. Almost 100 years have passed since the completion of Naidaijingawa Power Station, and 97 years since the completion of Tsuru Power Station. By this renovation, we will renovate the turbines, power generators and so forth to high-efficiency instruments in order to increase the maximum output and the annual generation amount while keeping the approved water intake amount at the present level. We will advance the construction with sufficient consideration for the environment and safety.

Hydraulic power generation is a precious, purely domestically produced energy having low carbon dioxide emission, which is friendly to the environment. Our Company 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 providing a stable supply of energy in future years.
