Impact of new generation by SECI Energia’s hydro power plants on transmission networks of Srpska Republic of BiH and neighboring South-East Europe countries - Security analyses and needed grid reinforcements -

Main objective of this study was to evaluate the impact of the generation produced by new HPPs, planned by SECI Energia in the basin of Drina river (HPP Buk Bijela (124 MW), HPP Foca (56 MW), HPP Paunci (38 MW), HPP Mrsovo (44 MW) and HPP Cehotina (40 MW), on the transmission grid of BiH from the load-flow and security analyses point of view. The possible grid congestion caused by the new HPPs generation had to be assessed and with reference to BiH’s network as well as more broadly with BiH internal and cross-border grid. In case of found congestions proposal of network reinforcements had to be made.

A second part of the study was security analyses over possible network congestion, determined by future electricity trading activities from BiH to Italy through the new TERNA’s planned undersea interconnection Italy-Montenegro, into the transmission networks of BiH, as well as most adjacent and concerned grids, particularly the ones of Serbia and of Montenegro.
