HEDNO Substation and Network Upgrade Projects Serving Industrial Areas (IAs)

Within the framework of State Aid Scheme Action 16634 “New Industrial Parks” of the General Secretariat for Industry of the Ministry of Development, funded through the National Recovery and Resilience Plan “Greece 2.0”, HEDNO has implemented substation and network upgrade projects in nine (9) Industrial Parks to serve existing Industrial Areas (IAs).

Purpose of the Projects

The measure aims to modernize the country’s energy infrastructure serving Industrial Areas (IAs) and to enhance the capacity of the distribution network through targeted interventions involving the upgrade and undergrounding of Medium Voltage (MV) networks, as well as the reinforcement of Substation capacity. These targeted interventions ensure the full accommodation of increased electricity demand from both existing and new industrial customers, within the Industrial Areas as well as in the surrounding regions. At the same time, they significantly improve service quality and the reliability of the electricity supplied, while enhancing the overall efficiency and operational security of the distribution network. A key strategic benefit of these projects is the maximization of the integration of new Renewable Energy Source (RES) installations, effectively promoting modern energy-saving, energy storage and clean energy distribution solutions.

The projects have been implemented in the Industrial Areas of  Xanthi, Kavala, Florina, Serres, Ioannina, Kilkis, Komotini and Lamia, as well as in the Industrial Park of Sapes, with 100% funding of eligible expenditure.
