The TOR will developed when resources are in place. Open 5

6 DAM Products Request to PCR SC to provide provisional approval was granted Test results due to be presented 6 Nov JCR 253 added an additional milestone for final approval in 04/18 Tests including data provided by GME (Slovenia) complex (failed) complex + blocks (on hold) Failing poses a significant risk to I-SEM go-live Test results escalated internally and to RAs Letter written to PCR SC stating full unconditional approval was needed PCR result Next steps Escalation depends on PCR result Change request to JPB for complex only for I-SEM go-live 6

8 SO Cross Border Actions (including CTPT) BLG November 2017

9 Background I-SEM Design The I-SEM design did not address SO cross border TSO actions however the general scheduling and dispatch related decisions apply to cross-zonal actions (from SEM ): Insofar as it is possible, the ex-ante markets should be left to resolve the energy supply/demand balance. TSOs should not take any action prior to gate closure unless it is for reasons of system security e.g. reserves, for priority dispatch or for other statutory requirements. Ensure that costs for non-energy actions are economically incurred 9

11 TSO Cross Border Actions (CBA) Interconnector instructions are a method by which EirGrid, SONI and NGET can exchange services across Moyle and EWIC and are generically known as a Cross Border Actions The Interconnector Operating Protocol defines the mechanisms available to alter interconnector flows: Cross Border Balancing (CBB) service, available up to 2 hours before the start of each half hour delivery period. This service may be withdrawn by either TSO prior to a CBB request being made. A trade does not have to be agreed on request. Emergency Assistance (EA) service, manually initiated and entered as a CBB trade expost. Such a request should be met unless the other TSO foresees a difficulty in maintain security on its own transmission system in meeting the request. Emergency Instruction (EI) service manually initiated and settled ex-post. May result in an NTC curtailment. Static Frequency Response service automatically triggers a change to ICRP following a frequency event, entered as a CBB trade ex-post. Dynamic Frequency Response service may also vary the flow. This may need to be settled as a CBB trade ex post.

12 Drivers of Cross-Zonal Actions Driver 1. System Security 2. Priority Dispatch Description The requirement to limit IC flows to manage power system security issues. Assumes that there is no other re-dispatch option (or that other options have already been utilised) and that management of the IC schedule is the only solution available. E.g. to manage thermal loading on an IC associated transmission asset or to limit largest outfeed for system stability. Trading by EirGrid and SONI to limit SEM imports or to maximise exports to reduce priority dispatch curtailment in SEM. 12

13 Cross Border Balancing (CBB) Service Cross Border Balancing (CBB) is a mechanism for the System Operators to exchange energy across Moyle and EWIC. The existing CBB service will be retained in essentially its current format. CBB is also known as System Operator to System Operator (SO-SO) trading. These trades are used to manage unforeseen circumstances in real time and to avoid or minimise the curtailment of scheduled market flows on the Interconnectors. The CBB service can only be requested on a Firm Reference Program. Either TSO can re-declare Bid/Offer prices up until 2 hours before the start of the delivery hour. A trade does not have to be agreed on request. In accordance with its obligations under the GB Market Rules, NGET will publish on the internet both the prices NGET provide to SONI and EirGrid and the prices SONI and EirGrid provide to NGET. These are published on the GB market Information website ( SONI and EirGrid will publish both the prices NGET provide to EirGrid and SONI and the prices EirGrid and SONI provide to NGET and Cross Border Action (CBA) details.

14 Coordinated Redispatching and Countertrading Within 16 months after the regulatory approval on Capacity Calculation Regions (CCR), all the TSOs in each capacity calculation region shall develop a proposal for a common methodology for coordinated redispatching and countertrading. The Ireland United Kingdom (IU) CCR shall include the bidding zone border between Great Britain and the Single Electricity Market in Ireland and Northern Ireland. Each TSO shall abstain from unilateral or uncoordinated redispatching and countertrading measures of cross-border relevance. Each TSO shall coordinate the use of redispatching and countertrading resources taking into account their impact on operational security and economic efficiency. The interim solution on countertrading and redispatching is to utilise existing Cross Border Actions and to develop a third party countertrading solution (Coordinated Third Party Trading). This is the process by which a TSO contracts a third party to trade in a neighbouring intraday market so as to alter the cross-zonal flow for system operation reasons. The advantages of this type of trading over SO-SO trading is that actions can be taken with more flexibility and associated prices are also likely to be lower than the equivalent CBB trade price and with much higher volumes available.

15 Coordinated Third Party Trading (CTPT) The objective of CTPTs is to provide a flexible mechanism which facilitates coordinated energy trading (for system operational reasons) between TSOs within the capacity calculation region. Trades can be undertaken further ahead of real-time and for longer periods of time compared to those of Cross Border Balancing (which remains a component of wider SO Trading). CTPT will be used in the following circumstances: System security Priority Dispatch At any point during normal business hours either TSO can propose a CTP trade for consideration by the receiving TSO. The receiving TSO will have the right to reject the proposed trade where it is deemed to have a negative impact on secure, efficient, and economical system operation. Both TSOs have to agree any potential change in cross-zonal flow, the process is coordinated and meets the requirements of European Network Codes. It should be noted that trades should only be undertaken on a firm cross-zonal market schedule.
