The GRITA 2 Greece–Italy HVDC interconnection obtained the European Union’s Project of Common Interest (PCI) label as PCI 2.17 and was included in the 2nd Union list of Projects of Common Interest and Projects of Mutual Interest, covering the interconnection between Galatina (Italy) and Thesprotia (Greece). The list was adopted by the European Commission on 1 December 2025 under the TEN‑E Regulation (EU) No 2022/869, formally recognising GRITA 2 as a priority EU infrastructure project.
IPTO reports that a meeting is expected to be held in Rome in October 2025 to advance the technical maturity of the GRITA 2 project and initiate seabed research, signalling the planned start of geophysical investigations along the subsea route of the interconnection.
On 12 May 2025, IPTO (the Greek TSO) and Terna (the Italian national grid operator) signed a three-year Memorandum of Understanding in Rome for the GRITA 2 Italy–Greece HVDC interconnector and announced that they expect to invest approximately €1.9 billion in the 1,000 MW, ~300 km link, including about 240 km of subsea cable. The MoU establishes joint project governance and coordination of activities, including future joint tendering for cables and converter stations, framing this planned €1.9 billion outlay as the indicative project budget by the two TSOs.

GR–IT (GRITA 2) is a planned high-voltage direct-current (HVDC) interconnector to directly link the transmission systems of Greece and Italy. Promoted and governed jointly by the two national TSOs—IPTO (ADMIE) for Greece and Terna for Italy—it is intended to operate alongside the existing 500 MW ...

On 12 May 2025, IPTO and Terna signed a three‑year Memorandum of Understanding in Rome during the Italy–Greece intergovernmental summit, setting out the main terms, governance structure, and coordinated tendering approach for the design and development of the GRITA 2 HVDC interconnection between Greece and Italy, including joint management of cable and converter station procurement and implementation of the infrastructure.
By 2022, the feasibility study for the GRITA 2 interconnection had been completed, assessing alternative configurations to increase transfer capacity between Greece and Italy up to 1,000 MW and supporting progression of the project into further development stages.
GRITA 2 was first included in ENTSO-E’s Ten-Year Network Development Plan (TYNDP) in the 2022 edition, marking it as a pan‑European priority interconnection project between the Greek and Italian transmission systems. Subsequent communications note that the project continues to be part of later TYNDP cycles, including TYNDP 2024, underscoring its strategic role in reinforcing cross‑border capacity and supporting EU energy and climate objectives.
In 2020, IPTO and TERNA began close cooperation on the GRITA 2 Greece–Italy interconnection project, marking the initiation of joint development activities for the new 1,000 MW HVDC link between the two transmission systems.
