The Green Vein is a proposed high-voltage direct current (HVDC) subsea electricity corridor to transmit renewable energy from Egypt to northern Italy. Promoted by K&K Group in collaboration with CESI, Prysmian Group and Siemens Energy, the project was publicly unveiled at COP28 in December 2023 a...

By 23 October 2025, the Egyptian Electricity Transmission Company had signed a deal to carry out technical and other studies for the proposed Egypt–Italy HVDC interconnector, marking a further step forward in developing the Green Vein project.
Preliminary cable route engineering studies for the planned 3 GW, nearly 3,000 km Green Vein interconnection—covering the proposed route, landfall points in Egypt and Italy, and seabed depth profile—are expected to be completed by the end of 2024 by a Norwegian consulting firm appointed by the Italian side.
At Cairo Sustainable Energy Week on 1 October 2024, Egypt’s Ministry of Electricity indicated that preliminary studies for a nearly 3,000 km, 3 GW electricity interconnection between Egypt and Italy—including detailed route analysis, identification of starting points in both countries, and assessment of the Mediterranean depth profile—are being carried out by a Norwegian consulting firm appointed by the Italian side and are expected to be completed and submitted to the Egyptian authorities by the end of 2024.

Egypt–Italy HVDC interconnector, Green Vein
During Cairo Sustainable Energy Week, Egyptian Ministry of Electricity sources outlined the proposed financing model for the 3 GW, ~2,800 km Green Vein Egypt–Italy HVDC interconnector linking West Sohag to the Dolo substation near Venice, stating that Italy will cover the start-up costs of the interconnection while the Egyptian Electricity Transmission Company will earn revenue from the electricity transmission tariffs under the project. This cost-allocation approach is presented as a way to ensure the economic viability of the corridor while limiting Egypt’s upfront financial burden.
By 1 October 2024, the Italian side had appointed a Norwegian consulting firm to carry out preliminary studies for the 3 GW, roughly 2,800 km Egypt–Italy interconnection linking West Sohag to the Dolo substation, covering detailed route analysis, identification of starting points in both countries, and assessment of the Mediterranean depth profile.
By 5 December 2023, an initial feasibility study for the Green Vein electricity corridor between Egypt’s West Sohag and Italy’s Dolo substation had been successfully completed, providing the technical basis for a proposed 3 GW, ~2,800 km HVDC submarine cable reaching depths of up to 3,000 m and intended to carry green electricity from Egypt to Italy while supporting EU–MENA–Africa power system integration.
