A Methodology Proposal for Selecting the Optimal Location for Small Hydropower Plants

The hydropower potential in the Republic of Serbia, as the most important renewable energy source, has been estimated at around 17000 GW center dot h per year, where approximately 2000 GW center dot h could be obtained from small hydropower plants (SHP). Small hydropower plants in Serbia currently produce 150 GW center dot h. Accordingly, the share of the electricity production from small hydropower plants in the total electricity production in Serbia is too small. The paper presents a model for the selection of optimal locations for small hydropower plants, which includes an ecological criterion, along with technical and economic criteria. The ecological criterion is eliminatory, i.e. those parts of the watercourse that border on or pass through protected natural assets are not taken into account when considering potential optimal locations for SHPs. All technical and economic criteria are included in the calculation of the weighted arithmetic mean with the aim of determining the optimal position for the construction of small hydropower plants. The model is implemented in the SHPOP software and its application is demonstrated on five watercourses in Southeastern Serbia.
