**Summary**: A French-led consortium and Greece are weighing a new route for the Great Sea Interconnector power cable to avoid Türkiye’s recently declared Fethiye–Kaş marine park near Kastellorizo, according to 09:46 UTC reports. The move pulls a flagship EU power link deeper into the Greece–Türkiye maritime dispute, raising fresh political and project‑risk questions for Eastern Mediterranean energy integration and French-controlled infrastructure assets.

## Detail

Greece and France are moving to redraw the map of a flagship Eastern Mediterranean power link, as they consider rerouting the Great Sea Interconnector (Crete–Cyprus HVDC cable) to bypass a Turkish-declared marine park off Fethiye–Kaş near Kastellorizo, according to open-source reporting filed at 09:46 UTC. With France now holding effective control over the project, the decision elevates a technical grid corridor into a live front in the long‑running maritime and EEZ dispute between Athens and Ankara.

The report states that in August 2026 Türkiye declared a new marine park in the Fethiye–Kaş area, overlapping waters long contested around Kastellorizo (Meis). In response, Athens and Paris are considering a revised seabed route for the high‑voltage direct current (HVDC) cable to avoid the park’s footprint. The project is now majority‑controlled (66%) by French infrastructure investor Meridiam; cable manufacturer Nexans will lay the line using a French‑flagged survey vessel. Greece and France have reportedly agreed to formally notify Türkiye before deploying the survey vessel, an acknowledgment that any misstep in these waters could trigger direct operational friction with the Turkish navy or coast guard.

For governments, this decision moves the interconnector out of the realm of pure energy policy into hard security and law‑of‑the‑sea politics. Athens gains a powerful EU‑backed asset buttressing its preferred EEZ framing, while Ankara faces a precedent in which an EU‑France‑backed project appears to route around a Turkish‑declared maritime conservation zone. If Türkiye perceives the reroute as de‑facto recognition of its claims, it may pocket the win; if it interprets the effort as a challenge wrapped in procedural notification, it can respond with new NAVTEX declarations, naval escorts, or legal and diplomatic pressure at NATO and EU forums.

On the ground and at sea, the immediate risk resides in the survey and pre‑lay phases. A French‑flagged vessel operating near Kastellorizo with Greek coordination will be a high‑visibility asset; any Turkish inspection attempt, close approach, or harassment would carry NATO‑ally‑on‑ally escalation risk. For Cyprus and Israel, the eventual completion of this interconnector remains central to future plans to export East Med power and potentially integrate green hydrogen and offshore wind; even a re‑routing that stays within schedule will be scrutinized for clues about how far EU states are willing to accommodate Turkish claims.

For markets, the Great Sea Interconnector is a backbone element in the EU’s strategy to knit Greek, Cypriot, and potentially Israeli grids more tightly into the continental system. Project‑schedule slippage, arbitration, or sanctions spats would not move spot power prices today, but could influence forward curves for Southeastern European electricity, the valuation of French and Greek infrastructure developers (Meridiam, Nexans, Greek grid operator IPTO), and risk premia on other Eastern Med energy corridors, including gas pipelines and future HVDC lines. Insurance costs for survey and cable‑laying operations in contested Eastern Med waters could also creep higher, affecting tender economics across the region.

In the next 24–48 hours, key pressure points to watch are: Ankara’s official reaction to any Greek‑French notification; issuance of new Turkish NAVTEX or advisories around the Fethiye–Kaş–Kastellorizo area; movement or public tasking of Turkish naval and coast guard assets; and statements from Brussels on the project’s ‘European interest’ status. Traders should track any signs of formal Turkish objections or interference with French‑flagged vessels, which would immediately raise the security premium on Eastern Med infrastructure plays and complicate the EU’s already fragile energy diversification plans.

**MARKET IMPACT ASSESSMENT:**
Medium-term relevance for European power market integration, Eastern Mediterranean energy geopolitics, and French/Greek utilities and contractors (Meridiam, Nexans). Any delay, legal dispute, or Turkish counter-move could alter risk premia on Eastern Med infrastructure, influence regional sovereign spreads, and marginally affect forward power pricing and green-transition infrastructure equities.
