Greece‑Cyprus Great Sea Interconnector advances

Overview

The Great Sea Interconnector (GSI) continues to advance despite regulatory and geopolitical complexities. By late August 2026, the project faced potential delays due to pending regulatory decisions in Nicosia, specifically regarding €50 million in outstanding electricity transmission system usage fees for 2024 and 2025.

Technical planning is ongoing, with stakeholders including ADMIE, Nexans, and Meridiam coordinating the next phase. While seabed surveys are complete within Greek and Cypriot territorial waters, research in international waters east of Kasos and west of Cyprus is still required. Project partners expressed a preference for using a specialized French vessel for these upcoming international surveys, rather than the Italian vessel used previously. If financial and regulatory hurdles in Cyprus are resolved, companies intend to request a NAVTEX for October to begin maritime operations.

In early September 2026, Greek authorities clarified the project’s licensing framework, asserting that the interconnection is licensed exclusively by Greece within its maritime jurisdiction under international law, requiring no joint authorization from third countries.

While Meridiam has moved forward as the majority shareholder, cable manufacturer Nexans has not yet received the full order to commence work. The project remains sensitive due to overlapping maritime claims between Greece and Turkey. This sensitivity is compounded by Meridiam’s own significant presence in Turkey, where it holds a hospital portfolio valued at over €2.3 billion.
