The small hydroelectric power generation jointly developed by ELIS has features which can generate electricity stably regardless of the weather if there is a stable amount of water such as existing rivers, artificial rivers, hydroelectric power plant discharge water, industrial water, and agricultural water. It can be said to be the ultimate eco-energy system from the viewpoint that it does not require a large amount of water and does not generate carbon dioxide at all. President Kuwahara said, "In the actual field, we received high praise for responding to issues such as topographical deformation at the time of installation, construction period, maintenance, and fluctuations in power generation efficiency due to flow rate increase / decrease, and for improving power generation efficiency."
