Developments surrounding the Great Sea Interconnector project

As of late September 2026, the Great Sea Interconnector (GSI) project, aimed at linking the electricity grids of Greece and Cyprus, remains in a critical implementation phase. Recent reports suggested that Greece and France were considering a "light redesign" of the cable route to avoid areas affected by Turkey’s declared "Fethiye-Kas" marine park. However, Greek Energy Minister Stavros Papastavrou categorically dismissed these reports on September 29, stating that the project design remains unchanged. Government spokesman Pavlos Marinakis had similarly expressed no knowledge of any route adjustments earlier.

The project involves a consortium led by French firms Meridiam—which became a majority shareholder on August 5—and Nexans, alongside the Independent Power Transmission Operator (ADMIE). Greek Foreign Minister Giorgos Gerapetritis affirmed that the project is of European interest, noting that any obstruction of the cable laying, which is planned for the coming period, is unacceptable under international law. Greece is currently coordinating with France and the European Union to ensure the project proceeds without renewed tension.

Simultaneously, Greece is pushing forward with its own energy exploration, with seismic surveys by Chevron scheduled before the end of 2026 and exploratory drilling by a consortium of Energean, HELLENiQ ENERGY, and ExxonMobil set for early 2027. Athens is also evaluating the timing for potentially extending its territorial waters to 12 nautical miles south and west of Crete, a move closely watched by international stakeholders.
