Power Generation

The core business of JNC has transitioned since our foundation in 1906, but the main energy source in Minamata Factory has consistently been electric power from our hydroelectric power plant. We have carefully maintained and managed the hydroelectric power plant, which is a valuable property, for over 100 years by taking long-term measures against aging facilities. We established the Electric Power Business Division in 2013, and have promoted business based on hydroelectric power generation. Our company will take advantage of operation and management technologies cultivated so far to contribute to realizing a sustainable society, by a stable supply of clean energy.
