We generate sustainable, clean, and safe electric power in line with National legislation, international standards, and best industry practices.
The Shuakhevi HPP cascade incorporates the 178-MW Shuakhevi HPP and the 9-MW Skhalta HPP, with relevant reservoirs, dams and one weir on the Adjaristsqali, Skhaltistsqali, and Chirukhistsqali Rivers.
The Shuakhevi HPP commenced commercial operations in 2020 followed by Skhalta HPP in 2021. The power generated by the Shuakhevi HPP is supplied to Georgia’s electric power system via the Akhaltsikhe-Batumi 220kV transmission line.
Powerhouse
The Shuakhevi power plant is located on the right bank of the Adjaristsqali river in the Shuakhevi municipality.
