Magistrsko delo obravnava tehnični in ekonomski del vrednotenja investicije v izgradnjo male hidroelektrarne. Tako je cilj magistrskega dela ugotoviti, ali ima reka Belca dovolj energetskega potenciala za investicijo v izgradnjo male hidroelektrarne. Na podlagi izmerjenega bruto padca in razpoložljivega pretoka vode je izveden preračun vseh glavnih sestavnih elementov male hidroelektrarne. Namen zaključnega dela je tudi ugotoviti, kako perspektivna je izgradnja male hidroelektrarne iz ekonomskega vidika. Na podlagi investicijskega vložka in obratovalnih stroškov je izvedena analiza upravičenosti investicije pri različnih odkupnih cenah električne energije. Podani so napotki potencialnemu investitorju, pri kateri odkupni ceni električne energije je realizacija projekta smiselna. The master’s thesis presents a technical and economic evaluation of investment into the construction of a small hydro power plant. The purpose of the master’s thesis is to establish whether the River Belca has enough energy potential to justify investment in the construction of a small hydro power plant. Based on the measured gross head and the available flow of water, all of the main constituents of the small hydro power plant were calculated. Furthermore, the purpose of the final part of the thesis is to establish how economically feasible the construction of a small hydro power plant would be. Based on the investment value and operating costs, an analysis of eligibility of the investment was carried out for different buying prices of electricity. Instructions for potential investors are presented which show at what buying price of electricity realisation of the project would be reasonable.
