DESFA S.A. (Hellenic Gas Transmission System Operator S.A.) is responsible for the operation, management, utilization, maintenance, and development of the National Natural Gas System (NNGS) in Greece. The company ensures the safe, reliable, and economically efficient transmission of natural gas, playing a crucial role in Greece's energy sector. DESFA's activities include providing access to the NNGS, managing gas flows, and developing new infrastructure to meet evolving energy demands and enhance regional connectivity. It also operates the Revithoussa LNG Terminal, a key facility for diversifying gas supply sources for Greece and Southeastern Europe.
