EirGrid and SONI have therefore included the Consolidated ES as Appendix C and Consolidated ES Addendum as Appendix D of this JER. The JER is being submitted to the planning authorities in both Ireland and Northern Ireland. In circumstances in which the Consolidated ES and Consolidated ES Addendum has already been submitted to Planning NI, the Consolidated ES and Addendum have not been appended to the version of the JER submitted to Planning NI as to do so would be unnecessary duplication of reports previously submitted and consulted upon in Northern Ireland.

EirGrid and System Operator for Northern Ireland (SONI) (the respective applicants) are jointly planning a major cross-border electricity development between the existing high- voltage transmission networks of Ireland1 and Northern Ireland. The proposed interconnector is a 138 km 400 kV overhead line between a planned substation2 in Turleenan, County Tyrone and the existing 400 kV substation in Woodland, County Meath. It is described in greater detail in paragraph 22 of the Joint Environmental Report (“JER”) which this Non-Technical Summary (NTS) summarises. 2. The proposed interconnector will provide a second electricity interconnector between Ireland and Northern Ireland, and is planned to be constructed within the counties of Tyrone, Armagh, Monaghan, Cavan and Meath. The existing interconnector is a 275 kV overhead line and connects the existing Tandragee and Louth substations. 3. As the proposed interconnector is being developed in Ireland and Northern Ireland, separate planning applications have been submitted in each jurisdiction for the EirGrid section of the proposed interconnector (the EirGrid Proposal) and SONI's section of the proposed interconnector (the SONI Proposal). The applications are accompanied by an Environmental Impact Statement (EIS) and Environmental Statement (ES)3 respectively, prepared in accordance with European Union (EU) and national requirements for Environmental Impact Assessment (EIA). 4. EirGrid and SONI and their consultants have closely coordinated their activities to ensure an integrated approach has been undertaken to the design of the proposed interconnector
