Distribution network operator DEDDIE/HEDNO will use Recovery and Resilience Facility (RRF) funds to cover a considerable proportion of an investment for capacity boosts at certain existing low and medium-voltage substations around the country to facilitate the entry of new RES units.
The capacity boost at these substations, it is estimated, will enable grid entry for new RES units with a total capacity of approximately 1,755 MW.
This prospective RES addition represents nearly 40 percent of the 4,640 MW in new RES unit entries planned for the achievement of National Energy and Climate Plan (NECP) RES penetration goals.
This DEDDIE/HEDNO investment will cost close to 30 million euros, of which 12 million euros will stem from the RRF.
Substations in the Peloponnese and Epirus, northwestern Greece, will be boosted by 250 MVA. Substations in the wider Athens area will be boosted by 100 MVA, such facilities in central Greece will be boosted by 200 MVA, and Macedonia and Thrace units in the north will be boosted by 250 MVA.
All project contracts are expected to have been finalized by the fourth quarter of 2023, while the projects are scheduled to be completed by the fourth quarter of 2025.
