Prysmian Secures €910 Million Contract for Greek Island Subsea Grid Interconnections

## Prysmian Wins €910 Million Greek Island Grid Interconnection Contract Italian cable and connectivity solutions group Prysmian has secured a landmark framework agreement valued at approximately €910 million with Greece's Independent Power Transmission Operator (IPTO/ADMIE) to deliver subsea electricity grid interconnections for Greek islands, according to Offshore Energy. The contract represents one of the most significant subsea cable awards in the European energy infrastructure sector in recent months, and underscores the accelerating pace of grid modernisation across the Mediterranean as European nations work to integrate renewable energy sources and improve energy security. ### Project Scope and Strategic Significance The framework agreement covers the design, manufacture, and installation of high-voltage subsea cable systems connecting Greek islands to the mainland transmission grid. Greece operates one of Europe's most complex island electricity networks, with dozens of inhabited islands historically reliant on isolated, fossil-fuel-dependent power systems. Interconnecting these islands to the national grid is a cornerstone of Greece's energy transition strategy, enabling the export of locally generated renewable energy and reducing dependence on diesel generation. For Prysmian, the award reinforces its position as a leading contractor in the European offshore and subsea cable market. The company has been active across several high-profile interconnector and offshore wind cable projects throughout Europe, and this latest contract adds substantial backlog to its order book. ### Broader Energy Infrastructure Context The Greek island interconnection programme aligns with wider European Union energy policy objectives, including the REPowerEU plan and targets for cross-border electricity interconnection capacity. Subsea cable infrastructure has emerged as a critical enabler of the energy transition, facilitating the movement of offshore wind and solar power across national and regional grids. The scale of the Prysmian award — nearly €1 billion under a single framework — reflects the capital intensity of modern subsea grid projects and the long-term investment commitments being made by European transmission system operators to future-proof their networks. Further project details, including specific island routes, cable specifications, and delivery timelines, are expected to be disclosed as individual call-off contracts are placed under the framework agreement.
