Hydromatrix - Ashta power station in Albania

Ashta I and II in Albania

Ashta Hydromatrix power plant

The Ashta I & II hydropower project is located on the Drin river near the city of
Shkodra in Albania and comprises two power plants of similar design.

The tailrace of Ashta I consists of a 6 km long canal connecting the two plants and an additional diversion channel connecting the plant with the Drin river. The Ashta II plant has a similar arrangement to Ashta I and its tailrace will be connected to the Drin river by a short canal.

Each power plant is equipped with 45 Hydromatrix TG units mounted in one row at the upstream face of a concrete gravity dam structure. They can be raised
individually for service purposes. The accompanying draft tubes are embedded in the newly built dam structure.

Ashta I became operational in May 2012, with Ashta II following in the fall of the same year.
