With a total length of 37.5 km, the Shuakehvi Hydropower Plant (HPP) tunnel in Georgia is now the second longest hydropower tunnel in the world.
The world’s longest hydropower tunnel is located in Iceland at the Kárahnjúkastífla Dam and has a length of 39.7 km. The third longest tunnel, with a length of 34.4 km, is located in Norway at the Evanger HPP.
Until now, the longest hydropower tunnel in Georgia was the Enguri HPP tunnel with a length of 15.3 km – a much shorter tunnel than the one constructed for the Shuakhevi HPP.
The Shuakhevi HPP is being built by Adjaristsqali Georgia LLC and is the first hydropower project in Georgia certified by the United Nations Framework Convention on Climate Change for carbon emission reductions. The power station is expected to produce about 450 gigawatt hours of power annually and reduce greenhouse gas emissions by more than 200,000 tons per year.
Once the construction of the Shuakhevi HPP has been completed, Georgia will have a clean energy power station with an installed capacity of 187 MW. All electricity generated during the winter months will be exclusively for the use of the Georgian people. During the summer, when there is a surplus of power, electricity will be exported to Turkey.
The Shuakhevi HPP represents an investment of USD 416 million and employs 730 Georgian citizens. Once construction is complete, the power station will be jointly operated by a team of Georgian and foreign professionals.
