HEDNO plans 800-MW network boost to facilitate RES projects

Distribution network operator DEDDIE/HEDNO is planning a series of significant network upgrades to facilitate new RES project additions to the grid through the availability of an additional 800-MW capacity over the next few years.

Many of these network upgrades, set to commence, are investments that will be co-funded by Greece 2.0, the National Recovery and Resilience Facility.

DEDDIE/HEDNO stands to receive 30 million euros from the RRF for capacity upgrades at selected medium and high-voltage substations around the country, either through transformer additions or full replacements.

Many of the operator’s prospective network upgrades are expected to be completed over the next 12 months, energypress sources have informed. All operator upgrades inducted into the RRF are planned to be completed by the fourth quarter of 2025.

The capacity of substations in the Peloponnese and Epirus regions is planned to be boosted by 250 megavolt-amperes, the wider Athens area will get a 100-MVA boost, substations in central Greece are expected to receive a 200-MVA lift, while substations in the country’s Macedonia and Thrace regions are headed for a 250-MVA capacity boost.
