Sub-station upgrades to maximize RES grid connections

Distribution network operator DEDDIE/HEDNO is closely examining the country’s power grid to determine which sub-stations it will choose to upgrade, the objective being to offer grid links to a greater number of RES projects.

The operator also intends to upgrade sub-stations in areas where investment interest for RES installations is high.

Grid capacity limits are already exhausted in areas where RES development has been extensive, especially when concerning RES technologies other than photovoltaics.

As part of the upgrade, the operator intends to modernize all necessary equipment at each substation, the cost of which it considers manageable.

Also, the operator will carry out studies to determine necessary network interventions close to each substation, especially replacement of conductors with small cross sections.
