In a pivotal development for energy infrastructure in Southeastern Europe, Romania and Georgia have formalized their collaboration to establish a strategic electricity link across the Black Sea. The two nations’ transmission system operators, Transelectrica from Romania and Georgian State Electrosystem, have signed a memorandum that lays the groundwork for a planned submarine interconnection.
This agreement signifies a progression beyond initial concept phases, with essential feasibility studies already completed. The interconnector has been incorporated into ENTSO-E’s Ten-Year Network Development Plans for both 2022 and 2024, with ongoing efforts to secure its place in the upcoming 2026 edition. Furthermore, the project gained additional momentum after being recognized as one of the European Union’s Projects of Mutual Interest in December 2025.
The memorandum outlines a framework for cooperation between the two operators, focusing on advancing the high-voltage direct current (HVDC) connection that will link Romania and Georgia. This collaboration encompasses technical design, marine and environmental studies, social impact assessments, financing strategies, as well as joint representation in European and international forums.
Officials in Romania regard this partnership as a critical move towards establishing the country as a regional electricity hub. Strengthening ties with Georgian State Electrosystem is anticipated to bolster regional infrastructure development while supporting broader European energy objectives such as enhancing energy security, promoting cross-border market integration, and facilitating the expansion of low-carbon electricity sources.
The Black Sea submarine cable is not only an isolated project but part of a larger geopolitical and energy strategy. This initiative aligns with the Strategic Partnership Agreement on green energy signed in December 2022 by Azerbaijan, Georgia, Romania, and Hungary. Once operational, this interconnector is projected to diversify electricity transmission routes, improve supply security, and foster greater integration of renewable energy resources throughout the Black Sea region and into the European Union.
