NICOSIA, Cyprus — The European Union has voiced strong disapproval of Turkey’s threats to block an undersea electricity cable connecting the power grids of Greece, Cyprus, and Israel, according to Cypriot President Nikos Christodoulides. The project, known as the Great Sea Interconnector, aims to integrate Cyprus into Europe’s energy network and bolster regional energy security.

Speaking to reporters Friday, Christodoulides revealed that EU leaders, including European Commission President Ursula von der Leyen and Commissioner for the Mediterranean Dubravka Suica, expressed frustration with Ankara’s warnings. Turkey claims the cable’s planned route infringes on its continental shelf, a stance tied to long-standing maritime disputes with Cyprus and Greece in the Eastern Mediterranean.

“The EU stands firmly behind this project,” Christodoulides said, emphasizing Cyprus’s resolve to proceed under international law, particularly the UN Convention on the Law of the Sea. Cyprus views the €1.9 billion initiative as vital to ending its energy isolation, with potential to reduce electricity costs and enhance renewable energy integration.

Tensions flared after Turkey reportedly issued a naval notice asserting jurisdiction over parts of the cable’s path, raising fears of interference with ongoing seabed surveys near Crete and Kasos. Greece, a key partner, has reaffirmed its commitment, with Foreign Minister George Gerapetritis stating Thursday that the project will move forward “when the timing is right.” Israel also backs the interconnector, seeing it as a bridge to Europe’s power grid.

The dispute reflects broader regional frictions, including Cyprus’s division since Turkey’s 1974 invasion and competing claims over offshore resources. While Greece and Cyprus push for EU support, Turkey’s objections may complicate the project’s timeline, with analysts warning of potential escalations if diplomatic efforts falter.
