Pre-Defined Blocks for Intraday Continuous 22 Pre-Defined Blocks to be offered in IDC for Go-Live Pre-Defined Block One baseload block covering periods 1-48 Three 8 hour blocks Six 4 hour blocks Twelve 2 hour blocks Rationale Manage unit commitment and spread fixed costs across full-day where position not established through DAM/IDA Manage unit commitment and spread fixed costs across a longer period intra-day where position not established Widespread support from participants Access shorter blocks to allow participants to trade in and out of positions in advance of the balancing market and manage scheduling risks. 7

Pre-Defined Blocks for Intraday Continuous 8 originally proposed pre-defined blocks (baseload, peak, etc) not included concerns re complexity and over-lapping nature of blocks Increased number of blocks will increase complexity of user interface Recommend reviewing effectiveness after 12 months operation based on experience. Manage change through consultative committee. 8

FX Rate - Background Current signed-off solution in SEM and SEM-GB: SEMO (EirGrid/SONI) retrieves the FX Rate on D-2 from the ECB website at 16:00 CET Distributed to the SEM-GB NEMOs Same rate applied to DAM, IDA 1 and IDA 2 Agreed with all Regional Partners important to align a single GBP rate across SEM and GB markets Current solution in GB for the DAM: Nord Pool receive FX Rate from Nordea 15 mins before DAM gate closure Nordea continuously update FX rate Nord Pool publish the rate used on their own website Nordea publish rates 4 times a day Issue: NGIL have stated that while they are in favour of a transparent rate they could not accept one published so far in advance of the DAM gate closure

FX Rate - Requirements FX rate is used to convert GBP bids/offers into Euro Results provided in GBP using same FX rate ECC use separate FX rate to settle contracts SEMOpx preferred solution: Transparent rate that is static and traceable Published by a reputable source Maintain the same rate between SEMOpx and SEMO ECB Rate published at D-2 satisfies these requirements we acknowledge a rate closure to the DAM gate closure reduces exposure to rate fluctuations 11

FX Rate - Options 1. Multiple GBP FX rates SEMOpx uses GB Solution, SEMO uses ECB D-2 rate System and procedural changes SEM Participants dealing with 2 FX Rates between SEMO and SEMOpx Less transparent SEMOpx and SEMO using ECB D-2, GB parties using current GB solution Lower system and procedural changes Participants that operate in both GB and SEM will need to manage 2 FX rates May need additional agreements, likely additional costs 2. SEMOpx and SEMO address the timeliness issue of transparent rate Lowest system and procedural changes Modification to TSC for timing of FX rate publication Changes to the systems to interface with new FX rate

FX Rate Next Steps Identify publicly available source that satisfies SEMOpx requirements and NGIL concerns over timeliness Seek agreement from NGIL Apply changes to solution TSC modification procedure will be followed 13

Interim Modifications Process - Background K.4 sets out the need for an Interim Consultative Forum until the enduring Exchange Committee has been appointed Purpose: to consult on further development and finalisation of proposed Rules and Procedures Changes to the Rules have arisen to facilitate unforeseen concepts and to modify certain paragraphs Finalisation of the Procedures is needed 20

MCF Background Regional Coupling Pre-coupling Coupling Participants bids and offers Cross-zonal Capacities and Constraints For Moyle, EWIC, and ROI-NI CZC for SEM PMBs Bids & Offers Market Participants NP submit CZC for IFA EPEX submit CZC for Britned

MCF Background Regional Coupling Validation of Results Financial Settlement Physical Settlement Final PMB Results Netting of financial positions between CCPs Post-coupling Submission of XB Nominations Congestion Rent Collection of congestion rent and submission to JAO (acting on behalf of the ICOs Shipping

MCF Market Coupling Contract SEMOpx is responsible for the allocation of the interconnector capacity The congestion rent is the consideration for the allocation of capacity For the congestion rent to be collected ECC must clear the capacity To clear the capacity it must be a product on the Exchange Market Coupling Contract (MCC) The MCC is only available to one member type -> the Market Coupling Facilitator (MCF) Only Interconnector Owner (or their agent) may become the MCF Changes to the Rules necessary Does not impact other member type Draft Rule and Procedure changes will be presented 13 Feb 27

3 - Invalid Contracted Quantities - Background A modification has been raised to the TSC to provide a workable solution to how specific low probability risks related to imbalances, due to invalid Ex-Ante Market Contracted Quantities, are mitigated in the I-SEM, given the interrelationship between the Ex-Ante Markets and Imbalance Settlement. Some elements of the solution would potentially require changes to the SEMOpx Rules, ECC Clearing Conditions, and Trading and Settlement Code. Presented last time Consultative Forum on this Queries raised and comments received since then to be addressed today. Revised proposal provided today

3 - Invalid Contracted Quantities - Scenarios Scenario Exchange Member trades in the Ex-Ante Markets before a Unit is effective in the Balancing Market Exchange Member trades in the Ex-Ante Markets while a Trading Halt should have been in effect. Exchange Member trades in the Ex-Ante Markets while a Suspension of the relevant Unit from the Balancing Market is in effect. Probability Extremely Low Very Low Extremely Low

3 - Comments and Responses 6 sets of comments received (3 agreed, 3 had reservations) Main Themes of Comments Exchange Member responsible firstly (6) Should never occur if automated processes (2) Use of Ex-Ante Collateral (1) Use Balancing Market Collateral (1) Incentives for SEMOpx to be careful (1) SEMOpx should cover risk and imbalances (3) Not all Exchange Members as a cost recovery measure (1) SEMOpx Rules allow all avenues for recovery (1) Reporting on occurrences by SEMOpx (1) Don t include default fund concept (6) (x) Indicates number of responses that raised this point 31

Amendments to Proposal Addition of trading out of Invalid Contracted Quantity positions as first step Confirmation that high likelihood of recovering costs (before impacting imbalance settlement payments) Use of Clearing Member or Direct Clearing Member collateral held with ECC Removal Default Fund from mitigations? Removal of socialisation of costs with all Exchange Members 32

*Items in purple added, default fund and charge all Exchange Members removed based on feedback 3- Invalid Contracted Quantities Recovery of Costs 1 ECC instruct the Exchange Member to close invalid contracted quantities by countertrades or will trade in Ex-Ante Markets to close position/minimise costs ECC Clearing Conditions 2 ECC withholding payment to the Exchange Member for the value of the invalid Contracted Quantities therefore minimising the costs needing recovery ECC Clearing Conditions 3 ECC to charge the Exchange Member that caused the invalid Contracted Quantities through trading in the Ex-Ante Markets, when not authorised to do so ECC Clearing Conditions 4 ECC to recover costs from the Exchange Members Clearing Member or Direct Clearing Member Ex-Ante Market collateral (as applicable) ECC Clearing Conditions 5 ECC to inform SEMO if payments cannot be recovered in time for Balancing Market payment deadlines. SEMO to withhold any payments for the relevant Units in Imbalance Settlement to minimise the costs needing recovery TSC Mod 6 SEMO to draw down on the Balancing Market posted credited cover for the Participant of the relevant Units prior to payments out due date TSC Mod 7 Where the issue can be attributed to SEMOpx s service provider, recovery of costs through liability provisions Service Provider Agreements 33

4 All Avenues for Recovery of Costs Rationale for Change To ensure SEMOpx Rules allow for all available avenues to recover costs of the Invalid Contracted Quantities from the Exchange Member. SEMOpx Rules clause G.3.3.1 means an Exchange Member is required to indemnify SEMOpx for losses and expenses arising from its breach of the Rules or the Procedures. Each of the situations that give rise to an invalid Contracted Quantity will now be a breach of the Rules. However, an additional clause in section G.3.3 so that the imbalance amount due to the invalid Contracted Quantity under the TSC is still considered a loss for SEMOpx under clause G.3.3.1 would provide further weight to ensuring SEMOpx has available all avenues to recover costs.

4 All Avenues for Recover of Costs Rule Amendment G.3.3.3 Where a breach of these SEMOpx Rules by an Exchange Member results in a Contracted Quantity submitted under paragraph F.2.2.1 of the Trading and Settlement Code being invalid under clause G.2.10 of that Code, for the purposes of the indemnity in paragraph G.3.3.1, the relevant Reassigned Amount (within the meaning of that Code) shall continue to be regarded as a loss incurred by SEMOpx. Note: G.2.10 is to be included as part of the legal drafting for MOD_17_17 35

Previously Raised Rule Changes Ref No. 1 No Trading when not authorised under TSC 2 Trading Halt if Clearing House requests Title Description Status Additional criteria to clause C 2.4.3 so that Exchange Member has the responsibility to not trade prior to the effective date under the TSC [adding to criteria of having responsibility to not trade when suspended or has a trading halt relevant under the TSC] Where Clearing House requests, SEMOpx can halt trading activity of an Exchange member (e.g. one or more of DAM, IDM1, IDM2, IDM3, IDC). New New 37

1 - No Trading when Not Authorised under TSC Text Change C 2.4.3 An Exchange Member shall not submit Orders in respect of Units registered in respect of a Participant under the Trading and Settlement Code where: a) the Order is for a Trading Period prior to the effective date and time of the Unit before the Unit s registration under the Trading and Settlement Code takes effect; b) the Participant has been Suspended under the Trading and Settlement Code; or c) the Market Operator is prohibited from accepting notification of Contracted Quantities in respect of that Participant under paragraph G.12.3.2 of the Trading and Settlement Code. 38

2 - Trading Halt if CCP request Rule Amendment C 2.4 Trading Halt C 2.4.1 SEMOpx may declare an Exchange Member to be subject to a Trading Halt if: a) the Exchange Member breaches these SEMOpx Rules, the Procedures or the Exchange Membership Agreement and SEMOpx considers that the breach adversely affects the operation of any of the Trading Systems or another Exchange Member s ability to interface with those systems; b) SEMOpx is aware that paragraph G.12.3.2 of the Trading and Settlement Code applies and, in accordance with that paragraph, the Market Operator is prohibited from accepting Contracted Quantities submitted by any Scheduling Agent in respect of a Participant who has a Unit or Units registered under the Trading and Settlement Code for which the Exchange Member is authorised by SEMOpx to submit Orders (with a term in italics in this paragraph having the meaning given in the Trading and Settlement Code); c) SEMOpx considers that it is necessary to do so to ensure the integrity of the Exchange in light of the SEMOpx Objective and SEMOpx Principles; or d) SEMOpx considers that the Exchange Member may have breached one or more of the conduct provisions set out in Chapter D; e) SEMOpx is are requested instructed to exclude an Exchange Member from trading by the Clearing House in accordance with the Clearing Conditions Rules. 39
