North-South 400kV Interconnection Development Final Re-evaluation Report April 2013

EirGrid plc has undertaken a comprehensive re-evaluation of the North-South 400 kV Interconnection
Development Project. The re-evaluation process included a review of a previous application to An Bord
Plean�la for planning approval (of what was then referred to as the Meath-Tyrone 400 kV
Interconnection Development), in order to ascertain whether the scope, content, conclusions of, and
rationale for that previous application remain applicable for the purposes of informing and shaping a
new application for approval of the planned North-South 400 kV Interconnection Development
(otherwise referred to in this document as �the North-South Interconnector Project�).
