ADMIE announced the announcement of the tender for the Corinth-Kos electrical interconnection, a project that is pivotal for the interconnection of the Dodecanese with the continental grid.

The tender process concerns the design, supply and installation of high voltage direct current (HVDC) cable systems, as well as two Conversion Stations, which will be built at both ends of the interconnection.

THE budget for the cable part of the interface amounts to 630 million euro, while for the Conversion Stations in 789.1 million euro.

The assignment of the project will be based on the most advantageous, from a financial point of view, offer. The duration of the construction phase is set to 36 months from the signing of the contract.

The second cable system with direct current technology, which will be installed in Greece, after the electric interconnection of Crete – Attica, will have a transmission capacity of 1,000 MW and will have a total length of 380 km.

As ADMIE reports, six autonomous electrical systems of the Dodecanese Islands (Karpathos, Rhodes, Symi, Kalymnos, Patmos and Arkia) are to be connected through the Corinth-Kos interconnection, shielding the safe electrification of ten more islands that are supplied indirectly by cables medium voltage.

The electrical interconnection of the Dodecanese will offer significant environmental and economic benefits, as it will allow for the gradual withdrawal of the polluting and costly oil-fired power plants operating to date on the non-interconnected islands.

The reduction in the cost of Public Utilities for all consumers is estimated to amount to up to 3.6 billion. euros for the period 2029 – 2053. The project has been selected for financing by the Island Decarbonization Fund.

The President and CEO of ADMIE, Manos Manousakis, said: “ADMIE continues to rapidly implement investments of strategic importance for the energy security and green transition of island Greece. The Corinth-Kos interconnection will connect, for the first time, the Dodecanese with the continental high-voltage system, paving the way for the full utilization of the onshore and offshore renewable potential of dozens of islands. With the construction of the second domestic interconnection with HVDC technology, ADMIE proves that it is at the “front line” of Operators pan-European who have the know-how for such complex energy projects. The new round of inter-island interconnections in the Dodecanese and the NE Aegean has already opened with the soon-to-be-completed tender for AC submarine cables. As our ten-year investment plan foresees, by 2030 all the major islands of the country will now be interconnected with the mainland, through modern and durable electrical infrastructures.
