Micro-hydroelectric power generation is a small-scale hydroelectric power generation method that generates power using the potential energy of small rivers and canals. It contributes to reducing CO2 emissions by making efficient use of energy.
Unlike large-scale hydroelectric power generation, micro-hydroelectric power generation makes effective use of small water resources to generate electricity. Toshiba Group has developed and commercialized Hydro-eKIDS™, a micro-hydroelectric power generation system designed for companies that are using water for purposes other than power generation, whose needs have been ignored in the past. Unlike conventional hydroelectric power generation systems, Hydro-eKIDS™ does not require large-scale civil engineering or construction work and can be used anywhere there are water sources available, including water supply and disposal systems, irrigation canals, wastewater from factories and water discharges from rivers. It provides an effective means of using these water sources as dispersed power sources and contributes to reducing greenhouse gas emissions and saving energy.

The Hydro-eKIDS™ series comprises five different standard unit models, with flows ranging from 0.03 to 3.5 m3/s, net head from 2 to 15 m and output capacities from 1 to 200 kW. These models are available for a wide range of applications. Units can be connected in series or in parallel to one another to be used in places where the net head is at a medium level and the water flow is large. Since the generator can be installed above a warterturbine, the system requires only a small space for installation and can be installed with simple foundation work. It has various characteristics, such as being easily connectable to existing water pipes using a pipeline structure. Compared to large-scale power generation systems, it has a smaller number of replaceable parts, reducing maintenance costs and the impact on the environment.
