It is not easy to provide the indispensable and adequate expert, geological, geo-mechanical, geomorphologic, land surveying, hydro-geological, hydrological, energy, environmental, environmental protection, and sociological bases for projecting small hydroelectric power plants. As a result, the elaboration of the project documentation and the construction of small hydroelectric power plants are delayed.
Težko je pridobiti nujno potrebne ustrezna strokovna, geološka, geomehanska, geomorfološka, geodetska, hidrogeološka, hidrološka, energetska, ekološka, naravovarstvena in sociološka izhodišča za projektiranje malih hidroelektrarn, zato prihaja do zamud pri izdelavi projektne dokumentacije.
