The hydro power plants in the basin of the Trebišnjica River are situated in two countries, Croatia and Bosnia and Herzegovina, and the Dubrovnik power plant is the last step of this hydroelectric system. Dubrovnik uses the waters of the Trebišnjica River from the Bileća reservoir which was created by the construction of the Grančarevo dam. The intake for Dubrovnik was achieved by the construction of the Gorica dam which creates a compensation reservoir. The Gorica dam is situated downstream of the Trebinje hydro power plant, so that the tail water of Trebinje is the head water of Dubrovnik. The power plant was planned to be constructed in two phases: phase one and some facilities of phase two are complete.
