Greek transmission system operator IPTO (ADMIE) has put the Western Corridor, a 400 kV Extra High Voltage transmission link connecting Megalopoli with Patras and Western Central Greece via an 18 km dual-circuit submarine interconnection between Rio and Antirio, into full operation, marking the first-time interconnection of the Peloponnese to the 400 kV system. The project strengthens the existing Crete–Laconia interconnection, alleviates congestion on previously 150 kV-only regional networks, enhances the security of electricity supply in the Peloponnese, and enables local thermal power plants to operate up to their maximum capacity, with Hellenic Cables responsible for the design, manufacturing, installation, protection, and connection of the submarine and land cables.
