Velebit is a pump storage hydro power plant. It is situated on the Zrmanja River, 10 km upstream of Obrovac. It uses watercourses of the Gračac Field, namely: Opsenica, Ričica, streams of Krivak and Otuča. In the pumping mode, the Velebit power plant in addition to the mentioned rivulets uses the waters of the Zrmanja River. In the latter case, using the nightly surplus of energy, it pumps the water from the lower reservoir Razovac into the upper reservoir Štikada in order for this same water to be used again to generate electricity.

Director: Nikša Vrkić
