 Constant improvement of technology of hydro turbogenerators from micro size (to 100 kW) to small ones (to 5 MW) results in growth of attractiveness of small and micro HPPs for electricity generation.

Small and microHPPs, depending on ways of their construction, are divided into reservoired power plants, derivational and channel ones which, in their turn, can be stationary or portable.

Reservoired small and micro power plants differ from large hydro power plants only by scales of hydro constructions and capacity.
