Work to modernize Greece’s electricity distribution infrastructure is moving forward without delays, with a major upgrade program expected to unlock roughly 600 MW of additional network capacity. The initiative focuses on medium- and high-voltage substations operated by the distribution system operator DEDDIE.
Financed through the EU’s Recovery and Resilience Fund (RRF), the project is tied to the country’s ninth disbursement milestone and is scheduled to be delivered toward the end of the summer, most likely between August and September. The scope of the works includes the replacement of outdated transformers with larger capacity units, along with the installation of new transformers where the existing infrastructure cannot meet rising demand.
A total of 14 substations were chosen following joint planning by DEDDIE and the transmission system operator ADMIE. Selection was based on a combination of technical and market factors, with particular emphasis on locations where interest in new renewable energy connections is strongest.
Although the overall program is governed by a common RRF timetable, each substation is being upgraded under its own detailed execution plan. Implementation is proceeding smoothly and no risks have been identified that could disrupt completion. Progress on the ground has been faster than initially anticipated in several cases, prompting expectations that some substations may be delivered ahead of the formal deadline, further easing network congestion and accelerating new connections.
