Cluster Substation Update Consultation

The purpose of this consultation paper is to present proposals to amend NIE Networks’ cluster connection charging methodology, as set out in NIE Networks’ Statement of Charges for Connection to the Northern Ireland Electricity Networks distribution system (the ‘SoCC’) Appendix 2. Ultimately it is NIE Networks’ view, that the existing network and current charging arrangements do not provide the capability to connect the volume of renewables required to meet 2030 targets in time without a level of change or investment. While these consultation proposals alone will not enable the 2030 targets to be met, they aim to be a step towards addressing the stagnation that currently persists.

This consultation seeks views on whether NIE Networks’ should:

  1. Amend the charging arrangements for assets needed to increase cluster substation capacity (e.g. second transformer), to align with the charging arrangements in place for the original cost of the cluster substation. Currently the costs of the second transformer are wholly chargeable to the customer that triggers the need and this is limiting the further development of existing clusters.
  2. For new Cluster sites, expand the scope of the generation that can be considered when designating a cluster i.e. to include generation that is at early stage planning, with an appropriate weighting factor applied, and to look at including two transformers from designation stage.
  3. At what stage NIE Networks should seek approval from the UR for costs associated with developing existing and new cluster substations.
