Coghinas hydroelectric plant
The plant, which was opened in 1926, is located in the province of Sassari on Lake Coghinas, a word that means “kitchens” in the Logudorese Sardinian dialect. In fact, further downstream the natural course of the Logudorese river passes through the Casteldoria geothermal area, where in the past the natural hot springs were used for cooking. This is the first “cavern” plant ever built in Italy, situated downstream from the dam – a construction 158 meters long and 58 meters high – 40 meters below the riverbed in a cavern spanning 82 meters in length.

Impact on the community
The reservoir, with its capacity of 223 million cubic meters of water, meets the drinking water needs of a large part of northern Sardinia as well as supplying water for irrigation to the intensive farms in the surrounding area. Populated by pink flamingoes, the reservoir is also a destination for birdwatching enthusiasts as well as for canoeists and anglers.
Enel Green Power and what was then the Olbia Tempio provincial administration also built fish ladders to enable eels to travel between the reservoir and the Coghinas River in order to reproduce.
