Hellenic Electricity Distribution Network Operator SA, known as HEDNO, is a Greek utility responsible for distributing electricity across the country, serving around 7.5 million customers on the mainland and the islands. The company maintains the network infrastructure—underground cables, overhead lines, and substations—to ensure a safe, reliable, and sustainable power supply for homes, hospitals, schools and other public services. It also connects new customers and distributed generators to the grid and plans extensions and upgrades to meet changing demand. Based in Greece and operating across the mainland and the islands, HEDNO is a major player in the electricity sector focused on distribution rather than generation. A recent development is a collaboration announced in June 2025 with Itron to modernize the grid and enhance the customer experience.
