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 130m (430feet). 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]
The power plant has two turbines with a nominal capacity of 41 MW each[2] having a total capacity of 82 MW.
The lake is 32km (20miles) long, with maximum depth of 130m (430feet). The maximum elevation of the lake is 469.9 m and it has a capacity of about 380 million m³ of water. There is an abundance of fish in the lake.
The construction of the dam started in August 1994 and it was complete in 2000. The reservoir started filling in May 2003, and the two power generators finally operated in July and September 2004.[3]
