The first test connection of the Damasta high-voltage substation with the electricity grid on the island of Crete was successfully completed on Sunday by Ariadne Interconnection, a subsidiary of Independent Transmission System Operator (IPTO). This is an important step toward the operation of the Crete-Attica electricity interconnection, a project being implemented by Ariadne Interconnection.
The substation is the largest on Crete, with a total of 17 gates, while it is fully digitalised and was constructed with the latest closed-type technology. It is a crucial part of the project, as it is the point where the island’s electricity system will connect with the Crete-Attica electricity interconnection.
The electricity interconnection entered the testing phase at the end of 2024 and is due to go into full operation in the summer of 2025. Its implementation is being carried out by contractors that include Siemens Energy, Nexans, Prysmian and NKT, while the cables were laid by the ships Aurora and Leonardo da Vinci.
