Azerbaijan's Black Sea underwater power cable project targets first line in 2032

The preliminary implementation schedule for the Caspian-Black Sea-Europe Green Energy Corridor has been announced. According to information on the project's official website, the first power transmission line is expected to become operational in 2032. It will follow the Baku–Ksani–Anaklia–Constanta South route, with an overland extension from Constanta South to Albertirsa, Hungary.

The second line, along the Baku–Tskaltubo–Poti–Domnesti route, is scheduled to enter service in 2036, and the third line in 2040. The corridor is expected to reach its full transmission capacity by 2040. The project envisages transmitting electricity generated from solar, wind and hydropower resources in Azerbaijan to Romania and Hungary via Georgia and an underwater cable across the Black Sea.

The three high-voltage direct current lines will each have a capacity of 1,300 MW, for a total of 3,900 MW. The schedule will be refined through a roadmap prepared ahead of the final investment decision. The feasibility study by CESI was approved at the 12th ministerial meeting of the participating countries in Baku on July 8, 2026.
