3 Gate Processing Approach Approach adopted by EirGrid (TSO), ESB Networks (DSO) and CER (Regulator) with Wind body Acceptance Developed from Pre 2005 experience of the earlier connection processes: Example of Sequential Approach MV 38kV 38kV/MV Stn 38kV 110/38kV Stn 38kV/MV Stn 110kV 3

4 Example of Sequential Approach MV? 38kV 38kV/MV Stn 38kV 110/38kV Stn 38kV/MV Stn 110kV Gate Processing Approach Driven by the scale of wind potential Since advent 2005, applications have been processed in blocks called Gates Within Groups, costs for shared assets are distributed on a per/mw basis Periodically, following consultation with the wind industry, criterion for inclusion in a Gate are agreed Structure of Gates to date have been quite varied 4
