Ariadne Interconnection, a subsidiary of the Independent Power Transmission Operator (IPTO), has successfully completed the Site Acceptance Test (SAT) for the cable system of the Crete-Attica electrical interconnection at the Koumoundouros Converter Station (Aspropyrgos), IPTO sources reported on Wednesday.
During the technical test, Ariadne engineers charged the two poles of the cable system, with a total length of 380 km, from one end of the interconnection to the other (Koumoundouros Converter Station-Damasta Converter Station), verifying that the cable is functioning properly along its entire length.
The construction phase of the project was completed in December 2024 and its launch is expected in the spring of 2025.
The project tests, which have already started since the beginning of the autumn with the preliminary equipment tests (pre-commissioning) and the functional tests of the subsystems, are in full swing. Upon completion of the above tests, the system acceptance tests will follow, which constitute the final and most critical check before the start of the trial operation of the Converter Stations.
The Crete-Attica electrical interconnection is the largest and most complex Electricity Transmission project in Greece, with a budget exceeding 1.1 billion euros, using cutting-edge direct current technology of bipolar design and nominal power (2x500MW) as well as Voltage Source Converters (VSC) at the Converter Stations.
