CRU has approved Modification No. 36 of the Distribution Code. The requirements stated under DCC11 are driven largely by the combined effect that large penetration of Non-Synchronous generation on the operation of the Transmission System. To date, this cohort of generation has comprised, almost exclusively of wind generation. It is now apparent that other forms of generation [most notably PV], which have an invertor between the primary source and the Connection Point, present the same technical challenges to System Operation. It is logical therefore that the same technical requirements should apply to them.
This approach is also consistent with that which will be taken upon adoption of the European Network Codes, most notably the Requirements for Generation [RfG], wherein the document structure is divided between Synchronous Generators and what are termed Power Park Modules.
Separately, the total quantum of generation connecting to the system has reached levels at which the quantum of un-controlled real power from distribution connected generation poses a threat to the stability of the power system. For that reason and for the reasons stated above with regard to the increase in solar generation connections, EirGrid deem necessary to make more of the PPM fleet MW controllable.

Proposal for General Application of RfG Requirements for Ireland
The consultation on the non-exhaustive parameters for the Requirements for Generators [RfG] has now closed. This proposal document is produced jointly by EirGrid plc in its role as the Transmission System Operator in Ireland and ESB Networks in their role as the Distribution System Operator in Ireland. This document contains the proposed parameters and explanations as to the reasons for their adoption, which are now formally submitted to the Commission for Regulation of Utilities [CRU] for approval. It also contains responses to the consultations and the System Operator replies.
