Bosnia and Croatia Advance Southern Gas Interconnection to Strengthen Regional Energy Security

Bosnia and Herzegovina and Croatia have formalized an intergovernmental agreement to advance the construction of the Southern Gas Interconnection, a strategic infrastructure project aimed at strengthening energy security and ensuring a more stable gas supply for Bosnia and Herzegovina.

The planned interconnection will provide Bosnia and Herzegovina with an alternative supply route via Croatia, reducing its current dependence on Russian natural gas delivered through Turkey, Bulgaria, and Serbia. By enabling access to new sources, the project is expected to significantly enhance supply resilience.

The agreement was signed in Dubrovnik during the Three Seas Initiative summit by Borjana Krišto, Chairwoman of the Council of Ministers of Bosnia and Herzegovina, and Croatian Prime Minister Andrej Plenković.

The pipeline network will span multiple routes, including Split–Zagvozd in Croatia, extending into Bosnia and Herzegovina through Posušje, and continuing across key locations such as Tomislavgrad, Kupres, Bugojno, and Travnik. Additional शाखing routes will connect areas including Mostar, Livno, Jajce, Tuzla, and Čapljina, creating a comprehensive distribution network.

According to the Council of Ministers of Bosnia and Herzegovina, the project will diversify both supply routes and energy sources, contributing to greater energy independence. The pipeline is expected to be supplied with gas from the liquefied natural gas (LNG) terminal on the Croatian island of Krk.

The signing ceremony was attended by US Energy Secretary Chris Wright and Vedran Lakić, Minister of Energy, Mining and Industry of the Federation of Bosnia and Herzegovina. US-based AAFS Infrastructure and Energy has been designated to manage the pipeline within Bosnia and Herzegovina.

Although the project has been under consideration for years, tangible progress accelerated recently. In January, authorities in Bosnia and Herzegovina indicated that AAFS Infrastructure and Energy would receive a 30-year concession. Subsequently, in late February, twelve countries from Central and Eastern Europe and the Balkans, including Bosnia and Herzegovina, reached an agreement with the United States to strengthen cooperation on LNG supply.

The Federation of Bosnia and Herzegovina, the entity through which the pipeline will pass, recently adopted a special legal framework (lex specialis) designating the US firm as the project investor. This decision has drawn criticism from the European Union, which warned of potential consequences.

Borjana Krišto emphasized that Bosnia and Herzegovina occupies a strategic position at the crossroads of energy flows in Southeast Europe. She noted that, beyond being a consumer, the country has the potential to play an active role in developing a more secure and resilient regional energy system. She also highlighted the importance of transatlantic cooperation in accelerating investment and improving market integration.

Prime Minister Andrej Plenković underscored that the agreement reinforces Croatia’s role as a regional energy hub, particularly by enabling the transport of gas from the Krk LNG terminal to Bosnia and Herzegovina. He also pointed to the broader significance of the Three Seas Initiative, which brings together 13 EU member states from Central and Eastern Europe to enhance connectivity between the Baltic, Black, and Adriatic seas, with a focus on infrastructure, transport, and energy integration.
