Gate 3 - Renewable Generation Group Processing

Group processing of connection offers for renewable generation takes a strategic approach to processing as proposed by EirGrid (as the Transmission System Operator) and ESB Networks (as the Distribution System Operator) in 2004 and approved by the CER.

Node Assignments

The System Operators have undertaken to update the node assignments list from time to time to confirm any changes to the Gate 3 tables originally published on the 19th January 2009. Changes are marked in yellow and a footnote is included explaining the high level reason for the change.

For any queries in relation to distribution applicants in this document please contact ESB Networks at For any queries in relation to transmission applicants in this document please contact EirGrid customer relations at or call 01 7026642.

Please note that the connection nodes listed are at voltages of 110/220/400kV. For Distribution connected applications, connection may be at 38kV or lower voltages. The actual connection method is determined from detailed studies. However, whatever connection method is chosen for given applications, they will ultimately roll up electrically (under normal feeding arrangements) to the listed nodes.

Node Assignments list - Updated 20.05.2011 (PDF | 244 KB)  and you can view a graphical representation of these areas on the Eirgrid website.
