A total of ten Greek grid interconnection and storage projects have been included in development plans set by ENTSO-E, the European Network of Transmission System Operators for Electricity, for up to 2030 and 2040.

They include an extension to the line running to Italy, the Euroafrica and Euroasia grid interconnections, an interconnection project for the south Aegean and its possible extension to Africa, new lines connecting Greece with Bulgaria and Turkey, a pumped-storage station in Amfilohia, northwestern Greece, two Cretan interconnections, as well as the GREGY north African interconnection.

In addition to 23 GW in transboundary grid interconnections being planned in the EU by 2025, authorities have also identified the need for a further 64 GW in projects, including storage units, at 50 European borders by 2030 and 132 GW by 2024.

Overall, the ENTSO-E plan includes 141 grid interconnection projects and 23 energy storage projects.
