The Evia–Andros interconnection is a 150 kV HVAC submarine electrical link between Livadi (South Evia / Euboea) and the island of Andros that was upgraded and re‑electrified as part of IPTO/ADMIE’s Cyclades Interconnection Phase B. The work replaced older oil‑filled single‑core cables with new XLPE 150 kV AC cable(s) to...

Project Timeline (6)
2020Commercial Operations Full Power
By early 2020, IPTO completed the upgrade project replacing the existing oil‑filled submarine cables on the Evia–Andros and Andros–Tinos links with new submarine cables, finalising the strengthened interconnection with Evia under Cyclades Phase B and ensuring reliable transmission of power from Evia to the interconnected Cyclades.
16 Dec 2019Capital Support Awarded
The Independent Power Transmission Operator (IPTO) confirmed that the new 150 kV AC submarine interconnection between Evia and Andros, together with the associated Andros–Tinos and Naxos Phase B works, is co‑financed by European Union and Greek state funds, with both projects together budgeted at about EUR 70 million. This capital support underpins the subsidised upgrade of the Livadi (South Evia)–Andros link, replacing older oil‑filled cables to strengthen the Cyclades North Corridor supply.

16 Dec 2019First Power
On 16 December 2019, IPTO (ADMIE) successfully completed the electrification of the new 150 kV AC submarine cable connecting Andros to Evia, marking first power flow on the upgraded Evia–Andros interconnection and strengthening the North Power Supply Corridor of the Cyclades.
19 Sept 2019Cable Supplier Selected
Independent Power Transmission Operator (IPTO) completed the tender for new 200 MVA lines on the Evia–Andros and Andros–Tinos interconnections and signed a contract with Prysmian as the contractor for the submarine cable replacement, reinforcing the Cyclades Phase B corridor. The award covers installation of increased-capacity XLPE cables as part of the broader Phase B works to reinforce existing connections alongside the Naxos–Paros–Mykonos loop.
Date TBDCable Installation Complete
Prysmian Group successfully completed the submarine cable laying operations for the interconnections between the Greek islands of Evia, Andros and Tinos, under a €21 million contract awarded by IPTO. The work included water installation using Prysmian’s cable-laying vessel Cable Enterprise, reaching a depth of 550 m on the Evia–Andros link and employing the first non-metallic armoured cable based on high modulus synthetic fibres.
Date TBDCable Installation Start
Under the second phase of the Cyclades interconnection, the installation of submarine power cables on the Evia–Andros and Andros–Tinos links was set to begin shortly after the article was published, marking the start of physical cable-laying works for these segments. IPTO’s contractor Prysmian was to commence work from Andros, installing two turnkey 150 kV HVAC three-core submarine cable systems totalling over 16.5 km offshore (plus associated land cables), with marine laying activities to be performed by the cable‑laying vessel Giulio Verne, upgrading the existing connections to increase transmission capacity.
