Abstract. The investigation was carried out on “small” hydroelectric power plants, which cause great damage to nature. Damp-free hydro-installation environmentally friendly solution proposed. It can be found in zones, which can be used to provide energy for small-scale, time-fed farms, camps, temporary events and similar meetings. It is designed for the transformation of the river's flow energy and can be used on various types of rivers and work all year round, as it is not exposed to ice floes.
