Assessment of the Technical Issues relating to Significant Amounts of EHV Underground Cable in the All-island Electricity Transmission System Public Report

TEPCO has carried out the following studies in order to evaluate the effect of cable
installations on the NIE/EirGrid network:
Part 1: Evaluation of the potential impact on the all-island transmission system of significant
lengths of EHV underground cable, either individually or in aggregate
Part 2: Feasibility study on the 400 kV Woodland � Kingscourt � Turleenan line as AC EHV
underground cables for the entire length
Part 3: Feasibility study of the 400 kV Woodland � Kingscourt � Turleenan line as mixed OHL /
underground cable

Investigating the Impact of HVdc Schemes in the Irish Transmission Network Report R1116.03.04 Final Report

The purpose of this study is to investigate the impact of HVdc schemes in the Irish Network and to compare these HVdc schemes to equivalent AC solutions for various scenarios. Four scenarios were investigated to compare various AC and HVdc schemes,
