Overview

The Shuakhevi Hydro Power Plant is an operational hydroelectric facility located in the Adjara region of Georgia (GE). As a run-of-the-river plant, it utilizes the natural flow of water to generate electricity, distinguishing it from reservoir-heavy storage schemes. The project was commissioned in April 2021, marking the culmination of construction efforts that began in 2013. The plant has an installed capacity of 185 megawatts (248,000 hp) and is operated by Adjaristsqali Georgia LLC. Its expected electricity output is 452 gigawatt-hours (1,630 TJ) annually, contributing significantly to the regional energy mix.

Technical Specifications and Infrastructure

The Shuakhevi HPP features a unique design that incorporates diurnal storage capabilities. The plant utilizes two reservoirs to store water for up to 12 hours, allowing operators to sell electricity during peak demand times for enhanced revenue optimization. This operational flexibility is supported by extensive underground infrastructure. Three main tunnels were constructed for the project: the 5.8 km Chirukhistsqali to Skhalta transfer tunnel, the 9.1 kilometres (5.7 mi) Skhalta to Didachara transfer tunnel, and the 17.8 km Shuakhevi headrace and pressure tunnel. Alstom was selected to supply the electromechanical equipment for the facility.

Engineering and Infrastructure

Hydraulic Infrastructure and Tunneling

The Shuakhevi Hydro Power Plant operates as a run-of-the-river facility in Adjara, Georgia, relying on a complex network of tunnels and reservoirs to manage water flow. The project’s hydraulic infrastructure includes three main tunnels constructed to transfer water from the Chirukhistsqali river system to the power house. These include the 5.8 km Chirukhistsqali to Skhalta transfer tunnel, the 9.1 km Skhalta to Didachara transfer tunnel, and the 17.8 km Shuakhevi headrace and pressure tunnel. The system is supported by two dams, Skhalta and Didachara, which facilitate diurnal storage. This configuration allows the plant to store water for up to 12 hours, enabling the operator to release water and generate electricity during peak demand periods, thereby optimizing energy output relative to market conditions.

Electromechanical Equipment and Capacity

Alstom was selected to supply the electromechanical equipment for the Shuakhevi project. The plant has an installed capacity of 185 MW (248,000 hp) and is expected to produce an annual electricity output of 452 GWh (1,630 TJ). The engineering design integrates these mechanical systems with the hydraulic infrastructure to ensure efficient energy conversion.

Ownership and Financing Structure

The Shuakhevi Hydro Power Plant is operated by Adjaristsqali Georgia LLC, a joint venture formed specifically to develop, construct, and manage the facility. The ownership structure of the operator is divided among three key international investors. Norwegian Clean Energy Invest AS holds a 40% stake in the company, while India's Tata Power also owns 40%. The remaining 20% is held by IFC Infraventures, an investment fund created by the International Finance Corporation. This tripartite ownership combines European, Asian, and multilateral investment interests to support the project's execution and long-term operation.

Why it matters

The Shuakhevi Hydro Power Plant represents a strategic milestone in Georgia’s energy infrastructure, specifically designed to address seasonal demand fluctuations and enhance regional export capabilities. As a run-of-the-river facility with limited storage capacity, its ability to store water for up to 12 hours in two reservoirs allows for diurnal load balancing. This operational flexibility is critical for the Georgian grid, enabling the plant to sell electricity during peak demand times, particularly during the winter months when hydrological consistency and thermal backup are vital. With an installed capacity of 185 MW and an expected annual output of 452 GWh, the plant contributes significantly to the national supply, helping to stabilize the grid against the variability of other renewable sources.

Regional Export and Grid Stability

Beyond domestic consumption, the Shuakhevi HPP plays a key role in Georgia’s energy export strategy, particularly towards Turkey. The plant’s location in Adjara and its connection to the regional transmission network facilitate the flow of power across borders, leveraging the country’s geographic position as an energy corridor. The project’s infrastructure, including three main tunnels totaling over 32 km in length, ensures efficient water transfer and pressure management, which is essential for maintaining consistent power delivery to neighboring markets. This export potential strengthens Georgia’s energy security and generates foreign exchange, reinforcing the economic viability of the region’s hydroelectric resources.

Financial Innovation and Investment Model

The development of the Shuakhevi HPP is also notable for its financial structure, marking the first limited recourse financing project in Georgia. This model attracted significant international investment, with the Asian Development Bank (ADB) and the European Bank for Reconstruction and Development (EBRD) extending a loan of up to 86.5milliontoAdjaristsqaliGeorgiaLLC,andtheInternationalFinanceCorporation(IFC)providinganadditional80 million loan. The project’s ownership is shared among Norwegian Clean Energy Invest AS (40%), India’s Tata Power (40%), and IFC Infraventures (20%), reflecting a diverse international stakeholder base. This financing approach not only de-risked the project for investors but also set a precedent for future energy infrastructure developments in the country, demonstrating the viability of public-private partnerships in the Georgian energy sector.
