Greece is undertaking significant enhancements to its electricity distribution network, aiming to add approximately 600 MW of new capacity. This initiative, spearheaded by the distribution system operator DEDDIE, focuses on modernizing medium- and high-voltage substations. The upgrade program is progressing without delays, reflecting a concerted effort to bolster the country’s energy infrastructure.
The financing for this project comes from the EU’s Recovery and Resilience Fund (RRF), with the initiative linked to Greece’s ninth disbursement milestone. The completion of these upgrades is anticipated by the end of summer, specifically between August and September. Key components of the project include replacing outdated transformers with larger capacity units and installing new transformers in areas where existing infrastructure cannot keep pace with increasing demand.
A total of 14 substations have been selected for upgrades through collaborative planning between DEDDIE and the transmission system operator ADMIE. The selection process considered various technical and market factors, particularly focusing on regions where there is substantial interest in connecting new renewable energy sources.
The upgrades are being executed according to a detailed plan for each substation, while adhering to a common timetable set forth by the RRF. Implementation is reportedly moving smoothly, with no risks identified that could hinder progress. In several instances, work has advanced more quickly than expected, leading to predictions that some substations might be operational before the official deadline. This advancement is expected to alleviate current network congestion issues and facilitate faster connections for new energy projects.
