Italian-headquartered global construction group Salini Impregilo has won an EPC contract worth more than £375 million ($575 million) for the design and construction of the Nenskra hydroelectric project in the mountainous region of Svaneti, Georgia.
The work, commissioned by the JSC Nenskra Hydro consortium composed of the Korea Water Resources Corporation [K-water], a government agency, and by the Georgian Government, represents a significant infrastructural priority for the Country.
The scheme, which will have an installed power of 280MW, will have to be completed in 62 months from the signing of the contract.
The project consists of a main dam, a weir on the Nakra river, a transfer tunnel, a headrace tunnel to the powerhouse and the actual open-air powerhouse with four vertical-axis Pelton turbines. The weir on the Nakra river will be 9 meters high and 50 meters and associated transfer tunnel, 14.4 km long with a 3.5 m diameter, will convey Nakra River’s water to the new reservoir, optimizing the Project’s performance. The headrace tunnel will be 15.6 km long with a 4.5 m diameter. The dam, an asphalt face rockfill dam, will be 135 meter high and 820 meters long (crest), with a capacity of 183 million cubic meters of water.
The Nenskra hydroelectric project will see Salini Impregilo, already active in Georgia with the construction of the Zestafoni-Kutaisi-Samtredia motorway, further consolidate its presence in the Caucasus area..
Salini Impregilo, which has operations in over 50 countries worldwide, was up against a number of European and Asian competitors bidding for the contract. The group specialises in the construction of major complex projects and is a leading global infrastructure company in the water sector.
