Greece investing over €61M in third Corfu-mainland interconnector

Greek transmission system operator (TSO) Independent Power Transmission Operator (IPTO) is investing more than €61 million to further strengthen Corfu’s energy security with a third subsea interconnector linking the island to the mainland.

The project will see the construction of the 21-kilometer 150 kV Corfu–Igoumenitsa interconnection, set to also enhance electricity reliability in the neighboring region of Epirus.

According to Greek daily newspaper Naftemporiki, IPTO is proceeding with the signing of the contract for the new high-voltage cable interconnection and FULGOR S.A. was selected as the contractor for a price of €61.19 million.

Looking ahead to 2026, IPTO said it continues to modernize transmission infrastructure across the Ionian Islands, from Corfu to Lefkada, Kefalonia, and Zakynthos, building a more resilient and reliable power system for the future.

To remind, the largest electricity transmission project in Greece, the Crete-Attica electrical interconnection, began operating at the end of May, fully integrating Crete into the national electricity system. The link completed a three-month testing phase at the end of August, marking entry into the final stage before official commercial operation.
