3. ESB Networks AIP Programme : 1. Review of where we are
Before the Special IGG of 7th June 2006, a first draft document ‘Impact of AIP on ROI Retail Market’ issued from ESB Networks AIP programme. This set out the impacts for the Irish Retail Market that had at that time been identified by ESB Networks as a result of the AIP, in so far as the requirements were known.
Before the IGG of the 22nd June 2006, all key design issues were included in Appendix 8 in the second draft of the discussion document. At the IGG on the 22nd June there was a walk through of each of the issues in that document.
Before the IGG of the 13th July 06, updated Appendix 8 issued on 7th July , ver 0.3, containing
feedback from Market Participants, SIMDRACS Co-Ordinator, new requirements that were received from Regulatory Authority, and review of Design Issues by ESB Networks.
Following the IGG of the 13th July 06, four Market Participants responded to specific queries
raised at that IGG.
At the IGG of August 10th 2006, the responses were debated.
In early August 2006, CER/SIMDRACS gave approval to proceed with the detailed design based
on what had been discussed to date with the IGG.
At the IGG of 21st Sept 2006 there was a recap of the high level design for AIP and an update on issues.
On 7th Oct 06 draft ver 0.4 issued, followed on 13th October by version 0.41 which had the marked-up changes of ver 0.4 removed. This document was reviewed at the Special IGG on 16th October. Option 3 of the Message Model was presented and all Market participants were asked to respond by 19th Oct.
MCRs issued in 3 batches over 24th,25th and 26th October All Market participants responded by 26th October to Option 3 : 4 in favour, 3 not. Option 3 of the Message Model was incorporated into these MCRs.

4. Conclusion

18. ESB Networks AIP Programme : 2. Review of Cutover
Cutover - Review
Cutover went well and to plan , with a small delay of a couple of hours during internal checks on Monday 29th October resulting in a delay with establishing connectivity with Retail Market Participants.
Extranet Upgrade
Following feedback after the last IGG, the timing of the Extranet upgrade was moved from the Friday of the cutover weekend to the morning of Tuesday 30th October.
MPRN DataSets
The MPRN Datasets issued on Tuesday 30th October and Thurs 1st Nov , and to PES on Mon 6th November.
Data Verification
We completed a Data Verification exercise with the SMO and Retail Market Participants in advance of Go-Live

19. ESB Networks AIP Programme : 2. Go-Live Operations
Overall successful with all Aggregations being issued to SMO on schedule
PDS are operating to D+4 timelines for QH data
New Interface for QH Import Reads for TCON sites from Eirgrid to ESB Networks is live
Percentages being used for Go-Live for the SLA % values for actual/est flags
As communicated in the update on Nov 1st , following responses from 4 Retail Market
Participants, the values implemented are the same as for Unscripted.
One respondent suggested that these values would be scheduled for review in 6 months time.
Error with SSAC value in 148 * 105 messages – Cutover Scenario C
There was an error with 148 of the 105 Market Messages , Cutover Scenario ’C ‘which issued
with the SSAC as per the 010 message instead of SSAC of ‘A’.
Not all Retail Market Participants were impacted , and each of those that were was contacted
on with a list of affected messages.
We apologise for this error.

20. ESB Networks AIP Programme : 2. Go-Live Operations……………….contd
Retail Market Messages - operating successfully with 2 minor exceptions viz.
a) the first day after Cutover there was a slower throughput than usual due to a backlog of
messages being processed.
b) The 595 QH Import Aggregation Message contained non-loss adjusted values in the field
‘LossAdjustedAggregatedConsumption’ in the lower level segment that is called
AdditionalAggregationinformation>AdditionalAggregationConsumption’ , from go-live.
Note that the data sent to the SMO was correct, no other messages or segments were
affected, and the CEDQ file for TSO was also unaffected.
Apologies for this, it was an error and is being handled as an urgent defect
We expect it to be corrected for 595 messages going forward for early next week, and MRSO
will let you know when this has been done.

21. ESB Networks AIP Programme : 2. Other Updates
Unscripted Market Trials
The Project continued to support UnScripted Market Trials until it finished on 1st Nov 07.
After this the Unscripted Market Trials Environment was unhooked from Retail Market
Participants’ test MPCCs and connectivity was disabled.
Trading Day/ Settlement Day testing with SMO
The Trading Day/Settlement day CR for new and deregistered Wholesale registered
Units were successfully tested in UnScripted and before Go-Live.
This SIMDRACS CR is now closed.
There are no new or outstanding MCRs or DRs

22. ESB Networks AIP Programme : Agenda
1. Review of where we are
2. Review of Cutover and Go-Live Operations
3. Items for Hand-Over
4. Conclusion

23. ESB Networks AIP Programme : 3. Items for Hand-Over - General
Note that the Project is now closing down, and the following slides give an update
on items that are outstanding from previous IGGs and new items

24. Data Queries and AD Hoc Aggregations Issue 20
ESB Networks AIP Programme : 3. Items for Hand-Over : Issues – B/Fd to November IGG
Data Queries and AD Hoc Aggregations Issue 20
Material Differences Issue 18
Consumption Adjustments inside or outside the 13 months Issue 19
The Ad-Hoc Aggregation facility is included in the design for use as and when required by the SMO to settle a Dispute , Data or Settlement Query or a Consumption Adjustment that can not be handled by scheduled aggregations.
Consumption Adjustments inside or outside the 13 months window are subject to ongoing proposals with the Mods Committee.
Further updates that impact the Retail Market will be provided by MRSO.

25. ESB Networks AIP Programme : 3
ESB Networks AIP Programme : 3. Items for Hand-Over : Issues – B/Fd to November IGG
Definition of Working days Issue 1
A Working Day for MRSO includes Bank Holidays but not Saturday and Sundays and
the SMO settlement calendar will have detais of any exceptions to this.
Calendar for Aggregation Issue 7
The Christmas Calendar for Aggregations is being discussed with SMO and it is
likely that aggregations will run earlier than would be usual.
MRSO will advise the calendar to the Retail Market once details have been agreed
with the SMO
Metering Responsibilities - placeholders in MCRs
This item is being handed over to MRSO

26. ESB Networks AIP Programme : 3. Items for Hand-Over : New Items
Potential Future Changes to the Design
[a] ‘RA324’
A SIMDRACS Modification to the T&SC has been proposed whereby Demand Data would never be Price-Effecting.
[b] Netting of Non-Participant Generator Data can result in Positive Interval values
It is expected that there will be a request from CER for a new Retail Market DR.
This is expected to allow for Supplier Unit Data in the 590/596 to contain positive interval values, instead of the current design where if, following the subtraction of all of the non-participant generation that is registered to a Supplier Unit, the supplier unit volume in an interval is positive then that supplier unit volume interval is set to 0 by MRSO before submitting the data to the SMO. An is currently issued to the Supplier in question and copied to the SMO by MRSO and this would no longer be required.
Further updates that impact the Retail Market will be provided by MRSO. .

27. ESB Networks AIP Programme : 3. Items for Hand-Over : Contingency
Contingency for Aggregation in the event of Major System Problem - Proposals
In the event of a major problem with the System, we are considering potential contingency
arrangements for Aggregations , and would like your views on the following proposals
Proposals
For Initial Aggregation, the proposed contingency is that the SMO would be asked to use the Indicative D+1 aggregation for the Initial D+4 aggregation
For Indicative Aggregation, the proposed contingency is that the Initial Aggregation data for the same day of the previous week would be sent to the SMO for use in the Indicative Aggregation. This would be sent by .
In either of these cases, the Retail Market 59x series of aggregation messages would not
be sent to Retail Market Participants . In these circumstances you would be notified that
the contingency arrangements are in place.
We are looking to understand if not getting these messages in an exceptional case
would cause you problems
Can you please send your comments to MRSO by COB Friday, 7th December
