Slovenia has formally expressed robust support for the Black Sea Energy submarine cable project, a pivotal initiative designed to transmit green electricity from the South Caucasus to European markets. The Slovenian Ministry of Environment, Climate and Energy underscored that collaboration with Azerbaijan in renewable energy stands as a paramount national priority, actively exploring avenues for direct participation in the project's implementation.

This shared strategic vision was solidified on April 4, 2025, with the signing of a Memorandum of Understanding between the energy ministries of Slovenia and Azerbaijan. The agreement specifically targets cooperation in renewable energy, clean technologies, and joint innovation, with a particular emphasis on hydrogen development, identified as one of the most promising areas for bilateral engagement. Slovenia is committed to supporting its domestic energy companies, especially transmission system operators renowned for their expertise in smart grids, energy storage, and hydrogen integration, in their global investment activities, including those in Azerbaijan. The ministry affirmed its backing for "all forms of collaboration in the fields of smart grid technology, hydrogen energy, and integration of renewable sources into the energy system," also noting the potential for research partnerships between Slovenian and Azerbaijani institutions.

Beyond bilateral initiatives, Slovenia welcomed Azerbaijan's expanding cooperation with the European Union in the hydrogen sector, signaling readiness to broaden joint efforts. The Slovenian government also commended Azerbaijan's leadership in organizing the upcoming COP29 climate conference, recognizing the nation's growing influence in the global energy transition and its strong presence within the International Renewable Energy Agency (IRENA).

The Black Sea Energy project aims to deliver up to 4 GW of green electricity to Europe via a high-voltage submarine cable spanning 1,155 kilometers across the Black Sea, with 1,115 km underwater and 40 km on land. This strategic partnership, initiated in 2022 by Azerbaijan, Georgia, Romania, and Hungary, and later joined by Bulgaria, will see its implementation through the "Green Energy Corridor" joint venture, GECO Power Company, established in 2024. The cable, rated at 525 kV with a capacity of 1,300 MW, is projected for completion by 2030, with an estimated cost of €3.5 billion, of which the European Commission plans to contribute €2.3 billion. A feasibility study by CESI confirmed the project's technical and economic viability, leading to its inclusion in the 2024-2034 ENTSO-E network development plan and submission to the European Commission for Project of Common Interest recognition.

Azerbaijan, historically reliant on oil and gas, is actively diversifying its economy towards a sustainable energy future, making the development of a green economy a key national priority. This aligns with the "Caspian-Black Sea-Europe Green Energy Corridor" agreement, signed in Bucharest on December 17, 2022, which outlines the transport of green energy from Azerbaijani wind power plants to Romania and onward to Europe.

In parallel, Slovenia is strengthening its cooperation with Azerbaijan in the natural gas sector, viewing Azerbaijan as a reliable partner for energy security and supply diversification, particularly through the Southern Gas Corridor. On August 1, 2024, the State Oil Company of Azerbaijan (SOCAR) commenced gas deliveries to Slovenia via the Trans-Adriatic Pipeline under a memorandum signed in July 2024. Azerbaijani gas accounted for approximately 5% of Slovenia’s total gas consumption in 2024, with ongoing discussions to increase volumes. Slovenia's annual gas demand ranges from 0.8 to 1 billion cubic meters. The Slovenian ministry emphasized the unprecedented closeness of energy cooperation between the two nations, with natural gas emerging as a crucial pillar of this expanding partnership. The April 2025 Memorandum of Understanding further reinforces shared objectives of enhancing energy security, accelerating the transition to cleaner energy sources, and diversifying Europe’s energy supply routes through deeper engagement with Azerbaijan.
