Electricity sales and community contribution business

Issues before installation

Since the installation site was in a heavy snowfall area, there were concerns (before installation) about the risk of flooding due to snow jams and the cost of dust countermeasures, but there were no problems at all, and the maintenance cost was reduced as garbage passed through the water turbine. It has been shown to be significantly reduced. In addition, it was a structure that can secure a fishway, which is difficult with a water-collecting type water wheel, so biodiversity can be taken into consideration.
