HEDNO: Grid capacity boost of 5 GW by 2025 for RES units

Distribution network operator DEDDIE/HEDNO plans to increase the network’s capacity by 5 GW to 13.5 GW by 2025 to facilitate RES output, Dimitris Vranis, the operator’s Director of the Network Users Division, has told an industry event in Thessaloniki.

The capacity goal set in the revised National Energy and Climate Plan for 2030 would, as a result, be exceeded, noted Vranis, while offering his views on the progress of PV and energy storage unit licensing at an annual event staged by POSPIEF, the Pan-Hellenic Federation of Photovoltaic Producer Societies.

A 25-GW objective has been set by the NECP for RES penetration by 2030, the official said.

Considering that half the RES units to be involved in this further penetration are expected to concern low and medium-voltage connections, the distribution network will need to be able to host projects representing 12.5 GW.

Given this projection, the operator’s aim for a distribution network capacity increase to 13.5 GW by 2025 exceeds the aforementioned capacity needed by 8 percent.

In addition, between 2025 and 2030, DEDDIE/HEDNO plans to further boost the network’s capacity by 2 GW, increasing it to 15.5 GW, Vranis told the POSPIEF event.

At present, RES facilities representing a total capacity of 6.5 GW are linked to the distribution network, the DEDDIE/HEDNO official noted.

Some 7,000 small-scale RES projects representing a total capacity of approximately 2 GW are now being developed, most of these PVs, while 5,300 units are privately owned and represent a capacity of roughly 400 MW, Vranis noted.
