Kazakhstan is discussing support for the Trans-Caspian green energy corridor with the European Commission, as work continues on a project to transmit electricity from Central Asia towards European markets, Kazakhstan's Energy Ministry said. 

The project is a joint initiative by Kazakhstan, Azerbaijan and Uzbekistan and is intended to create an energy corridor carrying green electricity from Central Asia across the Caspian Sea to Azerbaijan, with further access to European Union markets.

The initiative is currently at the preparatory stage. According to Kazakhstan’s Ministry of Energy, a feasibility study is being developed to determine the main technical parameters of the future corridor and its financial model. The work is expected to be completed in January 2027.

The Asian Development Bank and the Asian Infrastructure Investment Bank are financing the feasibility study, with around €1 million ($1.17 million) allocated for the work.

An organisational structure for the project has already been established. In June 2025, Kazakhstan’s KEGOC, Azerbaijan’s Azerenerji and the National Electric Grid of Uzbekistan signed a document on establishing a joint company that will be responsible for implementing the project.

Strategising energy exports to Europe

With specialists now assessing the technical and financial aspects of the corridor, Kazakhstan is also advancing the initiative at the international level. Discussions with the European Commission form part of this work as the three countries explore the prospects of exporting green electricity across the Caspian Sea towards the European Union.

The concept dates back to November 2023, when representatives of Kazakhstan, Azerbaijan and Uzbekistan discussed supplying green electricity through their territories to consumers in third countries, including EU member states. The project envisages laying a deep-water power cable along the seabed of the Caspian Sea.

The proposed route would carry electricity across the Caspian to Azerbaijan and then through Georgia, before crossing the Black Sea to Romania. The precise technical configuration and capacity of the corridor have yet to be determined.

Previous estimates from Uzbekistan give an indication of the project’s potential scale.

Energy Minister Jurabek Mirzamakhmudov has said the volume of electricity transmitted could range from 2 gigawatts to 5 gigawatts, depending on the capacity of the cable and the requirements of the participating countries. Deputy Energy Minister Umid Mamadaminov has estimated that the high-voltage transmission line would cost more than $2 billion.

The next key stage will be the completion of the feasibility study in January 2027. Its findings are expected to determine the technical parameters and financial model of the Trans-Caspian green energy corridor and provide the basis for decisions on its further implementation.
