Turkey intends to participate in the Caspian Sea–Black Sea–Europe energy corridor (Black Sea Energy) project, which is designed to ensure the supply of “green” electricity from the South Caucasus to the European Union market, said Turkish Minister of Energy and Natural Resources Alparslan Bayraktar.
According to him, the project involves connecting the power grids of Azerbaijan and Georgia, followed by the transmission of electricity via an undersea cable across the Black Sea to Romania and on to Hungary. At the invitation of the Azerbaijani side, Turkey expressed its intention to join the initiative and supported its implementation.
Ankara’s interest in the project is also confirmed by preliminary negotiations with Baku. On August 1, Azerbaijan’s Minister of Energy Parviz Shahbazov reported following a meeting with Bayraktar in Istanbul that the parties had discussed Turkey’s potential cooperation within the framework of the “Caspian–Black Sea–Europe” energy corridor and had also agreed to accelerate the implementation of other joint energy projects.
According to Bayraktar, cooperation between Turkey and Azerbaijan in the electricity sector is currently developing along three fronts.
The first involves integrating Nakhchivan’s power grid with Turkey’s and organizing electricity exchanges. In the future, this route could be connected to the main territory of Azerbaijan via the Zangezur Corridor.
The second direction is the “green” energy corridor connecting Azerbaijan, Georgia, Turkey, and Bulgaria. It is intended to facilitate the export of renewable electricity generated in Azerbaijan through Georgia and Turkey to Bulgaria and onward to EU markets. In August 2026, Baku and Ankara separately agreed to accelerate the implementation of this project.
The third initiative is Black Sea Energy itself. The main participants in the project remain Azerbaijan, Georgia, Romania, and Hungary. The four countries signed an agreement on strategic partnership in the development and transmission of “green” energy in Bucharest on December 17, 2022. The European Union supports the project, viewing it as a new supply route for renewable electricity from the South Caucasus to the EU.
In July 2026, the project moved to the next phase of implementation following the completion and approval of feasibility studies. The project operator, Green Energy Corridor Power Company, has begun developing the conceptual design, engineering solutions, and procurement strategy.
According to recent statements by the Azerbaijani side, the plan is to gradually export up to 3.9–4 GW of green electricity through the corridor, starting in 2032. The project has also been included in the TYNDP 2026 portfolio of the European Network of Transmission System Operators for Electricity (ENTSO-E).
A key infrastructure element will be a high-voltage subsea direct-current cable between Georgia and Romania. The preliminary construction cost is estimated at approximately 3.5 billion euros, with a construction period of three to four years. It was previously reported that up to 2.3 billion euros in European funding could be secured. However, in the latest Global Gateway documents, 2.3 billion euros is also cited as the indicative investment amount for the strategic Black Sea electricity interconnector, so the final financing structure for the project is still to be finalized.
The European Commission views Black Sea Energy as one of the tools for diversifying the EU’s energy supply and integrating renewable generation from the South Caucasus. The project is intended to connect the Caspian Sea region to the European power grid via Georgia and Romania, while also strengthening the energy resilience of the participating countries.
If Turkey joins, the project will take on additional significance, as Ankara will be able to participate in several parallel transmission routes for Azerbaijani “green” electricity to Europe—via the Black Sea and via the Turkey–Bulgaria overland corridor.
