Many Western countries in the past decade or so have transitioned from eagerly accepting cheap goods and investment from China without giving much thought to the consequences, to a degree of disengagement as a result of the PRC’s overt commercial and geopolitical expansionism, as well as anxieties over the security implications of Chinese dominance in the communications technology sector.

Crete-Attica power connection under way
The most complex power transfer project in Greece, the Crete-Attica electricity interconnector, is fully under way, with the completion of construction and start of testing due at the end of 2024, and commercial operation in the summer of 2025. The work is being carried out by Ariadne Interconnection, a wholly-owned subsidiary of Greece’s Independent Power Transmission Operator (IPTO, or ADMIE in Greek).

The start of cable-laying for the latest phase of the undersea connection between Crete and the Greek mainland was announced by the contractor on Monday 12th December. Carried out by Ariadne Interconnection, a subsidiary of the Greek grid management body ADMIE, the 335 km long 500kV DC cable linking Crete with Attica will mark the completion of the operation to connect the island with the mainland’s electricity grid. The “big connection” as it is commonly known, complements the “small connection” linking Kissamos with the Peloponnisos which was completed 18 months ago. The two between them are billed to permanently solve Crete’s electricity supply problems and at the same time allow the flow of power from Alternative Energy Sources (mainly wind and solar) from Crete to the mainland. They should also reduce energy bills for the Greek public, who currently pay a surcharge to ensure that electricity prices on Crete are no higher than those in the rest of the country.
According to the announcement, the cable, which weighs a total of 13,500 tons, will reach a maximum depth of 1,200 metres as it runs between Korakias in the nomos of Heraklion and Pachi Megaron in Attica. It is being laid by the ultra-modern cable laying ship Leonardo da Vinci, owned by the contractor Prysmian Powerlink. The operation, which is described as one of exceptional technical complexity, started at the beginning of December and is expected to to last about 9 weeks.
Following the completion of the Crete-Peloponnisos connection in July 2021, the ADMIE says it is proceeding on schedule with the country’s biggest power connection project to date. With a total budget of 1 billion euros, it is expected to be completed during the course of 2024. Of the undersea part of the project, the first 170 km of power cable have already been laid between Attica and Mylos, as well as the the complete run of fibre-optic cables with a length of 670 km.
At the Attica end, the laying of the underground cable sections is already under way, while work has begun on the foundations of the transformer stations to be built at either end of the connection, at Damasta, Heraklion, and at Aspropirgo in Attica.
The chairman and managing director of ADMIE, Manos Manousakis, told APE-MPE: “The ADMIE and its subsidiary Ariadne Interconnection are taking another important step towards the completion of the ‘big’ connection between Crete and Attica, carrying out one of the most demanding undersea cable-laying operations in the world. The second electrical connection of Crete with the mainland will bolster the island’s electricity supply, liberate its renewable capacity and strengthen its position on the energy map of Greece and the Eastern Mediterranean.”
The Works director of Ariadne Interconnection Angelos Stamatelos said: “Following the successful laying of the first section of the electrical cable between Crete and Attica, Ariadne Connection is proceeding with the installation of the second high-tension cable. During the next six months the subsidiary of ADMIE will have completed the installation of all the undersea cables and will concentrate on the equally vital terrestrial portion of the project.”
