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

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
![Page 13: Grid Development, Operation & Connections within EU Legal Framework](https://reader035.fdocuments.in/reader035/viewer/2022062501/568167b3550346895ddd0319/html5/thumbnails/13.jpg)
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

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
![Page 21: Grid Development, Operation & Connections within EU Legal Framework](https://reader035.fdocuments.in/reader035/viewer/2022062501/568167b3550346895ddd0319/html5/thumbnails/21.jpg)
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
![Page 24: Grid Development, Operation & Connections within EU Legal Framework](https://reader035.fdocuments.in/reader035/viewer/2022062501/568167b3550346895ddd0319/html5/thumbnails/24.jpg)
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
![Page 25: Grid Development, Operation & Connections within EU Legal Framework](https://reader035.fdocuments.in/reader035/viewer/2022062501/568167b3550346895ddd0319/html5/thumbnails/25.jpg)
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

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]
![Page 27: Grid Development, Operation & Connections within EU Legal Framework](https://reader035.fdocuments.in/reader035/viewer/2022062501/568167b3550346895ddd0319/html5/thumbnails/27.jpg)
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
![Page 28: Grid Development, Operation & Connections within EU Legal Framework](https://reader035.fdocuments.in/reader035/viewer/2022062501/568167b3550346895ddd0319/html5/thumbnails/28.jpg)
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 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
