Tirana River Cascade Hydropower Potential

• Tirana’s river watershed energy project, will include the constructions of two hydropower plants situated in two sites along the Tirana river flow Zall-Dajt and Brar.

• Average perennial flow rate is 2,7 cubic m/s. The output energy shall enter the 20 kV substation situated 1000 m far from the HP plant. The plant will be placed at approximately 8 km from the capital.

• A concession contract is expected to be concluded with the Ministry of Economy and Energy, once an investor shall be identified and will take it over.

• Construction permit will be granted by the Government following the presentation of a detailed design of the work.
