Wakayama Aridagawa Cho: Futagawa Small Hydroelectric Power Station
About The Facility
At the Futagawa Dam upstream of the Arida River, about 0.7 tons of water is constantly being carried out every second to maintain the environment in the downstream area.Aridagawa Town built a town-owned Futagawa Small Hydroelectric Power Station to utilize this unutilized energy.The turbine is a horizontal axis Francis turbine, the maximum output is 200 kW, and the annual predicted power generation is expected to be 1.2 million kWh.The electricity generated is sold to Kansai Electric Power Co., Ltd. based on the "fixed price purchase system of renewable energy" set by the country.
In addition, the obtained electricity sales profit is accumulated as a fund, and it is devoted to the support of the residents' eco activities (assistance for installation of residential solar power generation facilities, environmental education, etc.).
How We Work
Waste reduction, which is the pillar of environmental administration alongside energy, is greatly involved in the construction of this power station.
Although operating collection and transportation for recyclable waste took about 32 million yen per year before, high-quality recyclable waste has been appraised currently due to stationification of gathering sites and thorough separation of garbage by residents and administration, resulting in the revenue of approximately 2.6 million yen per year.
This power station was constructed utilizing the fund which accumulated this revenue and reduced processing cost.
In the future, we plan to build a sustainable mechanism such as further renewable energy projects and support for eco activities of residents so that we can also accumulate electricity sales from small hydropower generation as a fund.
Moreover, as a nationwide advanced example in which the town establishes a power plant alone in the prefectural multi-purpose dam in Japan, its introduction scheme attracts attention.
