RAE Decision 590/2021: the Greek Regulatory Authority for Energy (RAE, Rythmistiki Archi Energeias) issued Decision 590/2021 authorising the Cyclades Phase D interconnection programme, including the Lavrio-Serifos and Serifos-Milos 150 kV HVAC submarine links as well as the Milos-Folegandros and Folegandros-Thira segments. This regulatory decision establishes the project as a Major Project in the Greek transmission system planning framework and creates the legal basis for IPTO (ADMIE) to proceed with the investment. Date precision is year-only because the specific RAE decision date is not provided in available public sources; source is ADMIE's 2024 Sustainability Report (published November 2025) which references the decision number and year but not the specific issuance date.
