Greek Prime Minister confirms progress on Great Sea Interconnector project

On November 8, 2026, Greek Prime Minister Kyriakos Mitsotakis announced that Greece and Cyprus have officially issued the necessary permits for research and cable-laying operations related to the Great Sea Interconnector (GSI). This major energy infrastructure project, which also involves French companies, is classified as a project of common European interest. A corresponding NAVTEX was also issued on Friday to facilitate these operations.

Mitsotakis described the GSI as a strategic investment aimed at enhancing energy self-sufficiency, regional cooperation, and long-term stability in the Eastern Mediterranean. He emphasized that Greece and Cyprus hold the primary authority regarding the licensing of these activities. By moving forward with these technical steps, both nations aim to solidify their role in energy security and contribute to broader peace and stability in the region.

The project remains a significant point of geopolitical interest, with the Prime Minister using the update to send a clear signal regarding the sovereignty of Greece and Cyprus over the project's development. Future work will continue under the issued permits as the authorities coordinate the next phases of the interconnector's installation.
