What Grid Telecom Single Member S.a. does

Grid Telecom Single Member S.A. is a wholesale telecommunications provider headquartered in Athens, Greece, established in January 2019 as a wholly owned subsidiary of the Independent Power Transmission Operator (IPTO) of Greece. The company serves as IPTO's dedicated telecom commercial vehicle, providing integrated wholesale connectivity solutions to national and international telecom operators, hyperscalers, content providers, and large enterprise customers across the Balkans and Eastern Mediterranean region. Service portfolio is organized into three categories: Capacity Services (Layer-1 optical wavelength and Layer-2 Ethernet E-LINE/E-TREE/E-LAN at 1 Gbps to 100 Gbps, plus Dedicated Internet Access from 6 Mbps to 10 Gbps), Dark Fiber Services (long-term Indefeasible Right of Use leases over terrestrial and subsea fiber), and Colocation Services (rack and power hosting in IPTO's High Voltage Centers with N+1 redundancy, 24°C temperature control, and 24/7/365 NOC monitoring).

The underlying network comprises a proprietary DWDM backbone built with Space Hellas as contractor and Huawei as technology supplier, combined with a distinctive OPGW (Optical Ground Wire) cable infrastructure installed on IPTO's high-voltage power transmission towers. This OPGW approach delivers physically diverse routing versus conventional telecom backbones, enabling shorter paths and lower fault exposure. The combined terrestrial and subsea network exceeds 6,000 km, connecting 26 data centers and 24 national colocation sites, with international extensions to Albania, Bulgaria, North Macedonia, Turkey, Italy, Egypt, Cyprus, Israel, and Saudi Arabia. Subsea systems include the operational Minoas East-West and Apollo East-West cables (up to 35 Tb/s and 11.5 Tb/s per fiber-pair respectively), co-ownership of the 2Africa Crete branch (45,000 km, 33 countries), and the ARTEMIS system under construction (approximately 280 km, minimum 720 Tbps design capacity, positioned as the first petabit-class subsea cable in Greece and the Mediterranean).

Revenue is generated primarily through recurring capacity subscriptions, multi-year IRU lease payments, and managed colocation fees under quote-based pricing. Long-term contracts anchor the revenue base, exemplified by a 20-year framework agreement with Vodafone Greece for mutual fiber exchange and a 25-year agreement with Islalink for the IONIAN subsea cable connecting Italy and Greece. Distribution is exclusively direct enterprise field sales with no resellers, supported by executive-level relationships, CRM systems, and 24/7/365 NOC. The company is ISO 9001 and ISO/IEC 27001 certified and pursues international expansion through formal MoUs with strategic counterparties including 4iG Group (Albania-Greece), Dawiyat Integrated (Saudi Arabia), Quadrivium Digital (Crete CLS), Tamares Telecom (Cyprus/ANDROMEDA), ESO EAD (Bulgaria), and Telecom Egypt. Grid Telecom was named 'Dark Fiber Services of the Year in Europe 2024' by Telecom Business Review and 'Company of the Year 2023' at the Infocom World Conference.
