# Implementation of three submarine interconnections: Kalymnos–Leros, Leros–Leipsoi and Lefkada–Sparti–Skorpios

The buyer seeks construction of three medium-voltage submarine cable interconnections: Kalymnos–Leros, Leros–Leipsoi and Lefkada–Sparti–Skorpios. The works include seabed surveys, removal and disposal of existing cables, supply of 20 kV XLPE cables and associated materials and spares, installation, and testing to deliver the links ready for use. The buyer may omit the Lefkada–Sparti–Skorpios link within three months after contract signature. The notice lists one lot and an estimated value of EUR 58,422,185 excluding VAT, with a 28-month duration. It states specialist cable experience, turnover, registration and ISO-equivalent requirements; award is based on lowest price. The official TED notice gives a deadline of 26 October 2026 at 13:00 UTC+02, twelve hours later than the available notice information timestamp.
