The contract was awarded by the JSC Nenskra Hydro consortium comprising the Korea Water Resources Corporation [K-water] and the Georgian government.

Salini Impregilo won the contract beating out competition from the Europe and Asia for the 280MW project.

The project will comprise 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 asphalt face rockfill dam will have a capacity to store 183 million cubic meters of water.

The 9m high and 50m long weir on the Nakra river and the 14.4km long associated transfer tunnel with a 3.5m diameter will transport the river water to the new reservoir, optimizing the project’s performance.

Work on the project must be completed over a period of around five years, starting from the signing of the contract.

Upon completion of the Nenskra hydroelectric project, Georgia will be able to increase its energy exports, while contributing to the economic and social development of the country.

The project will guarantee the required energy supply during the winter season and to maximize the export capacity during the summer season.
