エリス List of Products and Services

Since around 2009, we have been conducting social experiments on standalone micro-hydropower generation in collaboration with local governments and consulting companies, optimizing the Takao Eris Power Plant in Niimi City, Okayama Prefecture, which has been operational since March 2016, and starting coordinated operations in Minami-Uonuma City, Niigata Prefecture, from December 2024. The turbine was developed in collaboration with Nagasaki University and Nishinihon Fluid Technology Co., Ltd.

Even with fluctuations in flow, stable power generation is possible. Maintenance is easy (measures against debris are straightforward). Fish passages can also be secured, allowing for consideration of biodiversity. Additionally, since it effectively utilizes flow velocity, there is minimal waste of energy, and the risk of overflow is extremely low.

Sustainable decentralized energy suitable for the natural environment WaterWeco(R) can generate stable power with minimal fluctuations through its unique patented mechanism, day and night, throughout the year. This initiative involves installing waterwheels in agricultural and industrial waterways scattered across various regions to effectively utilize natural energy. By conducting repeated demonstration experiments with numerous municipalities, universities, and research institutions, we mainly handle systems ranging from about 5 to 20 kW per unit. In wide waterways, it is possible to increase power generation by increasing the number of units through parallel installation. Since the mechanism does not negate the kinetic energy of water with structures like weirs, it can be directly transmitted to the waterwheel (the risk of overflow is also extremely low). Additionally, it is possible to ensure fish passages that take biodiversity into account (which requires prior ecological understanding and consultation with experts, depending on the species).

• Hydroelectric power

WaterWeco（R) enables stable power generation with minimal fluctuations throughout day and night, thanks to its unique patented mechanism. It is an initiative to effectively utilize natural energy by installing water wheels in small rivers and waterways scattered across various regions. Through repeated demonstration experiments with numerous municipalities, universities, and research institutions, it has been improved to generate electricity efficiently even at low head heights. The system primarily handles scales of several tens of kW. (Note: Power generation can be increased through parallel installation.) 【Features】 ■ Stable power generation with minimal fluctuations throughout day and night (due to unique mechanism) ■ Equipment utilization rate 5 to 8 times higher than solar power generation ■ Can be commercialized at a higher selling price than solar power generation when utilizing FIT ■ Lower environmental impact compared to large-scale hydroelectric power generation ■ Easy debris management (due to unique mechanism) ■ Maximizes flow velocity with an extremely low risk of overflow (due to unique mechanism) ■ High power generation efficiency (due to unique turbine) ■ Ensures fish passage and considers biodiversity (due to unique mechanism)
