Banjë HPP
Banjë HPP is the first HPP which started operation under the Devoll Hydropower Project. The project incorporated the previous unfinished dam structure built under the Banjë project. The new embankment dam with an impervious clay core is approx. 80 m high.
Banjë HPP started commercial operations in Autumn 2016. The useable head is between 175 and 95 m above sea level. The reservoir, with the highest regulated water level of 175 m above sea level, has a surface area of approx. 14 km². The reservoir extends from the dam nearly up to the town of Gramsh. The storage capacity of the reservoir is of approx. 400 million m³.
Details of the Fibre Optic Monitoring System
To monitor leakages, an automatic online fibre optic leakage detection system was integrated in the downstream filter. The system is based on the temperature gradient and the heat-pulse method.
