The strengthening of international interconnections and domestic electricity transmission infrastructures remain top strategic priorities in the Ten-Year Development Program 2024-2033 of ADMIE.
As the relevant announcement notes, the updated version of the DPA Preliminary Plan incorporates for the first time specific technical parameters of the new cross-border interconnections with Italy and Albania, which are expected to significantly upgrade our country's export potential for green energy. At the same time, it foresees new projects amounting to 147 million euros to strengthen the Transmission System in western and northern Greece, with a total budget of 550 million euros.
Greece-Italy electrical interconnection
According to the DPA 2024-2033 of ADMIE, the nominal transmission capacity of the submarine cable interconnection between Greece and Italy will amount to 1,000 MW, tripling the existing margin of electricity exchanges between the two countries, to 1,500 MW.
On a technical level, the new interconnection will be direct current, with state-of-the-art Voltage Source Converters (VSC) technology and electrode stations in Greece and Italy. The underwater length of the route is estimated at 220 km and the length of the underground sections in Greece and Italy at 55 km.
Electric interconnection Greece-Albania
The Operator's updated ten-year plan places the completion of the new 400 kV Interconnection Transmission Line between Greece and Albania by 2030. The interconnection will have a nominal transmission capacity of 1,600 MVA and will connect the Hellenic Electricity Transmission System (HETS) to the new Fier Substation in southern Albania.
The land international interconnection is estimated to have a total length of about 145 km, of which 45 km will be in Greek territory and 100 km in Albanian territory. The project is expected to increase transmission capacity between the two countries by at least 200 MW in both directions (to and from Albania).
