Dubrovnik Hydroelectric Power Plant

The Dubrovnik Hydroelectric Power Plant is located in Plat, approximately 15 kilometers south of the city of Dubrovnik, serving as a vital pillar of the energy system in southern Croatia. Built between 1960 and 1965, the plant harnesses the waters of the Trebišnjica River, which flows partially through underground karst channels. A unique feature of this facility is its cavern-type construction, situated deep within the rock, making it one of the largest underground power plants in the region. The energy generated here meets a significant portion of the demand for the Dubrovnik-Neretva County and is essential for regional cross-border energy exchange. Water is supplied to the turbines from the Bileća reservoir via a tunnel exceeding 16 kilometers in length. After power generation, the water is discharged directly into the Adriatic Sea. The plant holds strategic importance for grid stability and underwent major modernization following the Croatian War of Independence.
