Contributing to contemporary efforts aimed at maximizing the use of renewable sources of energy, and based on the interest expressed by both parties in developing strategic collaboration in the energy sector, Serbia and Italy signed a Collaboration Protocol in 2009. The Electric Power Industry of Serbia and SECI Energia S.p.A. from Italy were appointed as strategic partners for the implementation of a number of electric power generation projects.


The Electric Power Industry of Serbia and SECI Energia S.p.A. entered into a Preliminary Agreement on Collaboration in the Electric Power Sector, which includes a project for the utilization of the hydropower potential of the Ibar River Basin. To gain insight into available resources, spatial possibilities and construction constraints, and to arrive at a general concept for hydropower harnessing of the Ibar River, these two organizations commissioned Jaroslav Cerni Institute to prepare a technical reports package titled “Hydroelectric Power Plants on the Ibar River”.

The master plan developed within the scope of this project is comprised of 10 volumes:
Volume 1:     Report on Current Occupancy of the Area and Possible Alternative Solutions
Volume 2:     Report on Hydrologic, Meteorological and Psammologic Conditions for the Ibar River HPPs
Volume 3:     Report on Geological Conditions for the Ibar River HPPs
Volume 4:     Report on Hydraulic and Energy Assessments of the Ibar HPP Construction Options
Volume 5:     Report on Technical Solutions for the Ibar HPP Construction Options
Volume 6:     Report on Expropriation of Land and Structures for the Ibar HPP Construction Options
Volume 7:     Report on Economic Benefits of the Ibar HPP Construction Options
Volume 8:     Report on a Comparative Analysis of the Ibar HPP Construction Options
Volume 9:     Report on the Design Concept for the Proposed the Ibar HPP Option
Volume 10:     Report on Research and Investigation Programs for the Proposed Ibar HPP Option

 

he_ibar_02The concept for the utilization of the hydropower potential of the Ibar River between the cities of Kraljevo and Raška is determined by existing settlements and infrastructure (railroad line between North Kosovo and Central Serbia). As a result, a number of run-of-river HPPs with a small head have been proposed as a viable solution.

Several Ibar HPP options were considered. Economic and technical criteria led to the selection of the optimum option, comprised of 10 run-of-river HPPs between Lakat and Bojanić, with an installed discharge of Qinst = 100 m3/s, installed power of Ninst = 103.15 MW, and average annual output of E = 418.5 GWh/year (generally varying between 300 and 500 GWh)

The proposed concept complies with Serbia’s Spatial Plan and Water Management Master Plan. It will flood some 5.5 km of the highway from Raška to Kraljevo, where five HPPs (the Maglič HPP, Dobre Strane HPP, Bela Glava HPP, Cerje HPP and Glavica HPP) will be constructed. The railroad line will remain intact. Out of the available gross head of 155 m, this concept will utilize nearly 149 m.

The proposed dams are concrete gravity dams, with a wide controlled spillway and an adjacent power house. Each engineering building will accommodate two horizontal S turbines, compact turbines, and ancillary equipment.

The Ibar HPPs will form rather stable reservoirs (minor water level fluctuations) and will promote the development of tourism. They will not have an adverse impact on existing drinking water sources for the City of Kraljevo at Žičko Polje and Konarevo (increases in ecological flow rates will have minor positive effects).

Project cost has been estimated at some 285 million € (or 2,770,000 € per MW of installed power).
