The paper aims to explore the possibility of developing a Pumped Storage Hydropower Plant (PSHPP) within an existing complex hydro system on upper Barzava, by employing the given hydro potential of the accomplished water development. The present study analyses the hydropower parameters of a proposed Gozna-Semenic PSHPP, the power station looking to employ the existing Gozna water reservoir of a functional volume Vf 10.0 mill.c.m. The plant assumes also to accomplish some new works: an upper reservoir – Semenic, the headrace, the press water conduits, the tailrace etc. The specific elements of the proposed solution are fitted in the general scheme of the complex water development, in special relation to Gozna reservoir for which the water level variation is analyzed with respect to PSHPP running in closed circuit with a reversibility coefficient aof 0.7. The study looks also to form a technical base for the special operations at local level, specifically to the upper Barzava region, with a special interest in improving the integrate water employment in hydropower as an objective of the national and European general strategy and directives for the following decades.
