Investment

Small Hydro Power Plant – Orah, was chosen to be our first investment in the catchment of Sekularska river, and our team started construction of this plant in 2013. Using our previous good experience from construction of sHPP Jezerstica in the catchment of the Bistrica river, we decided to chose the same contractor in part of construction works Bemax from Podgorica, as company that proved that can meet all of our wishes regarding construction quality and desired deadlines. Hydromechanical equipment was also ordered from the same supplier Geppert GMBH as our partner on sHPP Jezerstica project, and GRP materials for penstock construction were purchased also from Turkish company Subor Boru. Middle voltage facility and control system were purchased from Sintaksa Split, company that proved that can provide us with highest quality and most advanced equipment produced by companies that are operating world wide and are meeting highest quality standards inside of European Union.

After construction of sHPP Orah and installation of the equipment necessary for safe operation of the facility on maximum capacity, this plant became operational in December 2014. Considering this plant as our second project that operates almost for six years, we can say that this facility is reliable energy source that provides our company with constant and safe energy generation.
