【Oil Industry Newspaper】February 1, 2021 Issue “Spreading mini-hydroelectric generation: 10 power plants in Japan, For the first time”


ELIS (President Jun Kuwahara), an environmental energy company in the Tsubame Gas (Headquarters: Okayama City, President Satoshi Kuwahara) group, is focusing on the spread of mini hydroelectric power generation. In September of last year, it registered a domestic trademark and obtained a patent for its own mini hydroelectric power generation system "WaterWeco®". Trademarks have been registered in China, Europe, the United States, and Taiwan, and world patents are pending. First of all, we will expand the spread in Japan, starting with 10 units.
The system, which was jointly developed with Nagasaki University and West Japan Fluid Engineering Laboratory, has features such as ▷ can be installed even with low head and low flow rate ▷ good power generation efficiency ▷ original remote monitoring system __. Water volume fluctuations occur in many agricultural canals where they are installed, but we have recently developed a new water turbine that can adapt to flow rate fluctuations. Power can be secured stably.
The company has been working on the spread of mini hydropower systems since 2007. In 2016, we signed an agreement with Tsuyama City and JA Tsuyama to install a mini hydroelectric power plant, and in 2018 we installed a mini hydroelectric power plant at the entrance of Kuroki No. 1 Campground in Tsuyama City. The operation was started as. The Kamo Kuwadani Power Station, which is managed by JA Tsuyama, is located upstream of the waterway, and the discharged water is used secondarily to generate electricity. The electricity produced is used at an electric vehicle (EV) stand installed in a nearby area, and is supplied to the small EV "COMS" that Tsuyama City uses for regional revitalization projects.
President Kuwahara served as a lecturer at the environmental event "Water School 2020" sponsored by the city, and cooperated in the production of videos on the water environment for elementary school students.
President Kuwahara said, "As a stable power source in the devastated mountainous areas, we would like to utilize it for the promotion of agriculture, fisheries, etc., centered on sustainable mini hydroelectric power generation." (Excerpt)
