In addition to wind power plants, diesel generators, solar plants, etc. mini hydro power plants in general, are an equal generating part of local energy systems (LoES). The proposed floating mini hydro power plant of a drum type (FD MiniHydro) to work in the LoES is an alternative device to existing implementations. For several reasons, the building of hydropower plants with an annual flow regulation and diversion hydropower plants even for remote areas seems in many cases difficult: they are located on the territory of nature reserves, alluvial estuaries of major rivers become silted (the villages are often located on the coast); energy consumption is low; investment is restricted. Therefore, attention has been drawn to the mountain tributaries of rivers with steep slopes of rocky beds with indicator flood flow rate of up to 4 m/s and the presence micro waterfalls. To overcome disadvantages of the dam and derivational hydropower plants, in the article there is proposed and investigated a floating mini hydro power plants of a drum type to work in the local energy systems (LoES). In the present technological solutions for FD MiniHydro power plants, there is considered riverbed drum unit (RDU) and coastal shield module (SCM). Also in custody there is presented classification of the hydraulic unit (RDU) with evaluation of its performance and speed qualities. The feasibility of installing FD MiniHydro is considered on the basis of the calculation of the water flow effective capacity on the example of the Bikin River, the village of Krasny Yar, Primorsky Krai. The resulting power value at the position of the lower RDU edge at the water level indicates the likely feasibility of the installing FD MiniHydro in this and similar areas.
