Grid Development, Operation & Connections within EU Legal Framework Michael Walsh 17th May 2013
Overview • Grid Development - Context and Challenges • Constraints Reports and ATRs • Gate 3 Offer Execution • DS3 Update
Grid Development Strategy to: Support energy policies: security of supply, sustainability, competitiveness, efficiency Facilitate economic growth in all regions Connect renewable and conventional generation Increase interconnectivity with other systems More than 300 projects €3.2bn expenditure
Programme Progress 2010 Actual • New Line - 130km completed • Line Uprates - 340km completed 2011 Actual • New Line - 80km completed • Line Uprates - 300km completed 2012 Actual • New Line -130km completed • Line Uprates - 215km completed 2013/14/15 Forecast • New Line –200 km due for completion • Line Uprates – 860 km due for completion 14 major station projects in the same period
Challenges • Ensuring Public Acceptance • Land access • Legal challenges • Legislation changes • Uncertainty of volume of Gate 3 work
Response • EirGrid/ESB Networks coordination on multi-Year Regional Programme Planning • Project Development & Consultation Roadmap • Stakeholder Engagement (local/national) • Community Gain • New Technologies
Overview • Grid Development - Context and Challenges • Constraints Reports and ATRs • Gate 3 Offer Execution • DS3 Update
3 pieces of the ‘information jigsaw’….. FAQs ATRs Constraints Published April-July 2013 Published April-July 2013 Published Dec 2012
FAQs and ATRs • Firm Access Quantities for all Gate 3 Wind were published in December 2012 • Determination of Associated Transmission Reinforcements is now complete • ATRs will be issued alongside the constraint reports
Constraint Reports • Studies for Gate 3 constraint reports have been completed following the publication of a final tie-break decision by the SEM Committee • High-level results available • Some general trends have been observed in the results • Detailed Area reports to be issued
Scenarios • Two scenarios covered: • 33% uptake of Gate 3 • This is achieved by derating all Gate 3 projects to 33% of their MEC. • 100% uptake of Gate 3 • The build-out rate is the same for both scenarios • This included project size, shallow connection leadtime, planning permission status etc
Build-out rate: 100% Gate 3 Large projects with planning assumed to connect ~4 years from offer acceptance Projects without planning take an extra 2 years
Build-out rate: 33% Gate 3 Average installation rate in Ireland of ~275MW/year
Observations on constraint results • Average levels are low for all years • There are some nodes that will have high constraints: • During uprate outages • Until uprates or new builds are delivered • Inside a constraint group • There are constraint groups – higher levels of constraint • Donegal • South West
Observations on curtailment results • High levels of curtailment if all of Gate 3 connects • Low levels of curtailment in the 33% Gate 3 case assuming: • Exporting of excess wind on the EWIC and Moyle • DS3 can deliver 75% SNSP* • No additional operational constraints to those modelled in the study

Gate 3 Offer Validity Period • Offer Validity Period is 50 Business Days and commences on receipt of Constraint Report • No Extensions to Validity Period • Modifications do not extend the validity period
TSO Offer Execution • To execute an Offer the Applicant must meet the conditions precedent which include: • Make First Stage Payment • Put in place MEC Bond (where applicable) • Sign the offer • After signing the applicant will receive an offer acceptance letter • Contains information including Long Stop Dates • 36 Months post Scheduled Consents Issue Date • 30 Months post Scheduled Operational Date • A Kick Off Meeting will be scheduled within 20 Business Days of Execution
Executing TSO Offer:First Stage Payment • The First Stage Payment (FSP) Mechanism* applies to Gate 3 Transmission Renewable Generators • This may be different to what is currently in your offer • A Sliding Scale Mechanism now applies to FSP • Full amount of the FSP may not be due on execution. • Amount due on execution depends on Scheduled Consents Issue Date • The remaining amount is due 12 months prior to your Scheduled Consents Issue Date. • First Stage Payments are non-refundable *CER/11/083
TSO First Stage Payment • Renewable Projects: • Contested • FSP = €10,000 per MW • Non Contested • FSP = Greater of [X and 10% of the connection charge] where • X = Lesser of [€10,000 per MW of contracted capacity (MEC); 50% of the connection charge]
Sub Groups • Project Starts when critical mass have signed • When enough MW has signed to warrant the connection works to go ahead • Members of same sub-group will have aligned validity period expiry date • Sub-Group Agreement is required for any modification that may change connection works • One party cannot unilaterally hold up progress on connection works by requesting a modification • If one or more parties wants to change the connection works e.g. AIS to GIS all parties must agree and seek to modify their agreements accordingly • Splits, Mergers, Relocations can all impact on connection works
Sub Groups - Continued • We proceed with connection works as set out in contract until a contract modification is signed • We cannot act on the basis of general discussions or hearsay • We must have contractual basis for progressing works/planning for something different from what is in the offer • This is for the protection of all parties within the subgroup and for the TUoS customer • COPP is a good source of information about sub-groups

DS3 Programme: Workstream Update (1) • System Services Review • Paper on Financial Arrangements submitted to RAs • Grid Code • All RoCoF Modifications submitted to RAs - Dec 2012 • Demand Side Management • WPDRS Phase Out, DSUs, Demonstration Projects • Renewable Data • 2012 Curtailment Report Drafted and submitted to Regulator • Performance Monitoring and Testing • Deadline for receiving Operational Certificates is 1st of December 2013 • Performance Monitoring Workshops: Belfast and Dublin on 6th and 11th of June
WFPS Controllability Update Status Update 1-2 slides
DS3 Programme Outlook • Project will evolve over the coming months • Enhanced role for the RAs • Progress for certain workstreams is dependent on other parties e.g. RAs, DSOs • Progress is dependent on decisions on System Services, RoCoF etc. • Move toward implementation of change in operational policies • Challenge of aligning all island position • Different Grid Codes • 2 Regulatory Authorities
