Construction worksHydroelectric power plant construction work

Currently, Japan promote the policy to make the best use of renewable energy resources as a effective measure to reduce the CO2 emission in our efforts to realize the low carbon society. Among the renewable energy resources, the hydroelectric power has been actively utilized for a long time in Japan. We have many track records of hydroelectric power plants at home and abroad covering from mid and small capacity to large capacity. We could propose the best hydroelectric power generation method based on the waterfall level and the water volume.
