Kozjak Hydro Power Plant
Kozjak Hydro Power Plant is a large hydroelectric power plant on the river Treska which creates an artificial lake Kozjak, the largest in North Macedonia. The impounded reservoir is stretched along municipalities of Želino, Brvenica and Makedonski Brod. The constructed Kozjak Dam is the tallest in the country at 130 m (430 ft). It is located in the western part of the country in the village of Lukovica part of Želino municipality. The primary purpose of the dam is flood control but it also serves for power generation.[1]
