The world’s longest and deepest undersea power and digital cable line is to be laid between the eastern and western shores of the Black Sea.

The commitment was made by the leaders of Azerbaijan, Georgia, Romania, and Hungary in Bucharest on December 17. The deal foresees the transmission of green energy from the South Caucasus to Europe, and forms part of the European Union’s (EU) wider plans for energy diversification; It was praised byCommission President Ursula von der Leyen as a project “full of possibilities.” 

Azerbaijan, a key producer of oil and natural gas, already plays a significant role in European energy security through recently agreed deals with the EU. In addition, both Azerbaijan and Georgia are important energy transit countries for Turkey, and Southern and South-eastern Europe. Key economic projects with geopolitical significance, like the Baku-Tbilisi-Ceyhan (running from Azerbaijan to Turkey) and Baku-Supsa oil pipelines, and the Southern Gas Corridor (again running east-west through Turkey) have elevated the importance of Azerbaijan as a major energy security player for Europe.  

The EU’s decision to support the undersea power line between Georgia and Romania represents a significant development. It will allow electricity produced in Azerbaijan, Georgia, and other countries to be delivered directly to the European market. It will also help clean energy-producing countries to attract more foreign direct investment in hydro, wind, and solar power generation. 

While Azerbaijan’s Caspian Sea wind farms may be the leading source of electricity for the power line,  a preliminary economic analysis has demonstrated that the participation of the other South Caucasus countries will be important for its ultimate commercial success. 

With the Russian invasion of Ukraine and the loss of Russian energy supplies, the EU’s need to diversify its energy sources, including both fossil fuels and renewables, is greater than ever. Naturally, this makes Azerbaijan increasingly important as a partner. The July 2022 visit to Baku of von der Leyen, and the subsequent signing of an energy agreement between the EU and Azerbaijan on increased natural gas supplies to Europe via the Southern Gas Corridor, have significantly elevated bilateral ties. That, in turn, has paved the way for a growing understanding of mutual dependence, as well as expanded collaboration on economic projects. 

While Russia is having enormous problems, it is also adapting and preparing for a protracted conflict. Despite multiple shortcomings, ranging from a lack of discipline and cumbersome logistics to sluggish command and control (C2) and inadequate intelligence, surveillance, and reconnaissance (ISR), Russian forces have stabilized a vast front, entrenched themselves, and increased the attrition for Ukrainian units, especially in the Donbas.  

This growing closeness serves as the backdrop for the most recent breakthrough by Georgia, Azerbaijan’s regional neighbor. The idea of the submarine power line between Georgia and Romania was born during the country’s partnership discussions with the EU back in 2018. The initial concept was based on Georgia’s interest in boosting its economic integration with the bloc, as well as the potential to export hydro energy to Europe. This led Georgia to request a pre-feasibility study from the World Bank, which was completed in 2020 (and is now publicly available.) The project, in turn, received a new boost with Azerbaijan’s interest in developing its vast wind power generation potential in the Caspian.  

Georgia is now moving forward to the feasibility study stage, funded by the World Bank, which should confirm the project’s commercial viability, optimal transmission capacity, and exact routing. It will also examine some of the technical challenges, including the difficult geography of the Black Sea, as well as the need to cross two undersea natural gas pipelines connecting Russia and Turkey. In addition, the feasibility study will assess a need for additional power infrastructure at the Georgian and Romanian ends in order to ensure the stable operation of their power grids. 

Initial costs estimates are around €2.5bn ($2.7bn), with one potential source of funding the EU’s funding European Economic and Investment Plan. Other finance may come from the European Bank for Reconstruction and Development (EBRD), the US International Development Finance Corporation (DFC), and others. Given the involvement of Romania and Hungary, both members of the Three Sea Initiative (3SI), it would be natural to have the 3SI Fund involved as well.   

There have been several past projects to transmit energy from the eastern to western shores of the Black Sea, but they have foundered because of an array of political, economic, and technical problems. These include the White Stream natural gas pipeline project to ship Turkmen gas to Europe via Azerbaijan and Georgia, as well as the Azerbaijan-Georgia-Romania liquefied natural gas (LNG) interconnector project.  

Yet this time there is a discernible political will to get the infrastructure built. The severance of Russian supplies was a serious shock for Europe and the urgent need to meet climate change objectives with greener energy are both providing significant momentum. The undersea power cable project has a realistic chance for implementation. That would blaze a trail for other projects to help boost connectivity in the Black Sea.
