• Ireland 2020 targets• 4GW
• Gate 3 = 3.9GW• Only require 55%• Future of PSO Contribution for wind beyond gate 3?
• Currently 13.5GW in queue BEYOND Gate 3
•Not possible to absorb domestically•Curtailment / Constraint
• Interconnector Exports?
Beyond Gate 3 (2025) – The Queue
Ireland & UK 2020 Targets Synergy
Ireland● Electricity from Renewables by 2020 – 40%
● Equates to 4 GW installed by 2020● 2 GW already installed● 0.25 GW p.a. required to reach target● 16 GW waiting in Grid Queue!
● Only requires 12.5% of current grid queue to reach2020 target
● Irish Wind potential = 345 TWh p.a.● Equates to 19 x market size● Significant opportunity to Export
UK● Electricity from Renewables by 2020 – 30%
● Equates to 35 GW installed by 2020● Currently 8.5 GW installed● 3.3 GW p.a. required to reach target● 22 GW in Grid Queue
● UK installed 0.7 GW in 2011
● LCPD – coal decommissioning
Political Stimulus
● Concept of export first raised at British Irish council 2011
● Declarations of intent made by both ministers June 2012 to enact legislation
● UK Energy Bill Dec 2012● Provides for projects outside UK REZ to
qualify for CfD’s
● Bi-lateral MoU now signed● IGA Q1 2014

Technology Development (Friends of the Supergrid – Technical Working Group)
● Increased power ratings for VSC (1,000 MW at 320 kV DC)
● Demonstrators for DC side fault clearing (e.g. DC Circuit Breakers)
● DC 320 kV cables with extruded insulation in operation at different onshore and offshore projects (500 MW per cable)
● DC cables with extruded insulation >320 kV developed
● MI-PPL 600kV (1.1GW per cable) developed and higher voltages in development
● MI >500 kV cable developed
● AC GIL in operation
● Standardization work for HVDC grids in CIGRÈ, CENELEC started
Today – 2015 (Supergrid Preparation Phase)
2015 – 2020 (Supergrid Phase 1)
After 2020 (Supergrid Phase 2)
