In my graduation thesis I was exploring the potential of Moţnica water resource. The Moţnica creek is
located in the municipality of Bovec, near the Log pod Mangartom village. The creek flows through
Triglav National Park and Natura 2000 area, which means that special rules apply in placing of the
hydroelectric power plant. The data obtained from the measuring station Moţnica led to my research
whether building a small hydroelectric power plant on the watercourse would be useful and profitable.
The water from the creek could also be exploited for supplying the Bovec-Čezsoča water distribution
system with drinking water. The water reservoir would be located in the area of source of the creek.
The water would be collected with the capturing of the source thus avoiding the contamination of
drinking water and providing sufficient amount of water for a small hydroplant. Considering the fall
and the power and water amount of the spring I decided for the use of Pelton turbine, which is the
most efficient. Calculating the energy potential I took into account two ecologically acceptable flows,
determined by two different approaches. With these two fluxes I determined the most optimal option
of the rated flow for the hydroelectric power plant.
