The delays were a result of performance issues affecting Market Systems. A short term solution is in place to improve performance. However, SEMO is working on a permanent fix with the vendor.
This was an operational oversight due to the Bank Holiday Monday. Statements and PIRs were published at the earliest opportunity the next working day.
Meter Data files were not submitted by MRSO on time. Indicative Settlement was delayed by one working day as a result
Initial Energy & VMOC Missing Combined Loss Factors
Data Submission

Invoicing - Week 13 ‘11 M+13 Currency Costs
Operational Error
23rd March – 4th April 2011
Currency values were not correctly applied to Week 13 2011 RS Energy invoices due to an operational error. M+4 values instead were applied in error. Further update to be given in relation to a resolution.
Initial Capacity - April 2012 P Type Statements Published
Operational Error
7th April 2012
Meter values for the 7th of April 2012 was mistakenly imported as Indicative (P) prior to the processing of Initial Capacity due to an operational error. As a consequence, P type files were published and a volume of data was missing from Capacity PIRs. F type Statements and PIRs were produced after invoices were published. Invoicing was not affected as a result of this issue.

Participant Connection Issues
Issue: Java error(JMS Messaging) – connection issues experienced by a Participant when
submitting COD.
Resolution: SEMO’s internal investigation was passed to the CMS vendor to cross reference and to revert
to SEMO with a plan to resolve. Issue was identified as a Java Messaging error. SEMO implemented elevated monitoring to catch the error & resolve. – This is has been
successful.
Next Steps: A workaround has been received and tested in current AMIE pre-production. The workaround script ‘recycles’ MI services on two MI servers.
SEMO is proposing to run the workaround script each evening at 7:50pm – no MI events are running and from a review of the logs no participant activity.
This process takes 15mins and connection requests during this period may fail. Deployment of the workaround script is due on Tuesday(22/5/12) This message queuing service is changing in IDT. Participants are currently testing with the new messaging service in place - IDT

CMS Oracle Database Archiving
Background Since 1st November 2007, all the data provided to SEMO or generated by SEMO has
been stored on the live system. This has impacted on system performance and the ability of SEMO to migrate
data for IDT.
The Plan: To improve performance of settlements and ensure that the migration of the Central
Market Systems Database from the current AIME environment to IDT can be achieved within a 12 hour window.
SEMO is proposing to archive the settlement data in the CMS on the 8 th June. This will require the CMS to go off-line for 12 hours.
6pm 8/6/12 to 6am 8/6/12
Once the archiving solution is implemented: The CMS database will contain 26 months of live data on line. SEMO will archive twice a year. 7 years of data will be available between offline and online

CMS Oracle Database Archiving
Additional Archiving Information
All Data can be provided on request, however if resettlement is required for periods beyond the 26 months, then data will need to be retrieved from the archive, based on a granularity of 1 month, which will require a full market outage.
The resettlement process time line and Market Outage will be communicated in accordance with the normal process, ( The likelihood of this type of resettlement being required is very low)
SEMO will have the capacity for Seven years in relation to SAN requirements to hold data off line.
The benefits of this are, increased performance and the ability to migrate within the 12 hour window.
The challenges are, if data is required following a dispute, or a general query the response/resolution time may be increased as the data will need to be retrieved from the offline store, and a market outage will be required.

SEM R2.0.0: Intra-Day TradingLegacy FTP - Report Timing
Some Participants continue to use the Legacy FTP site for provisioning of “Public Data” from the Central Market Systems.
As previously communicated it is not intended to upgrade the Legacy FTP site for future releases.
IDT release will impact the Legacy FTP site as follows:Where there are multiple versions of the same report (i.e. for each Gate Window) these will be copied to the FTP site as normal but they will have the same target filename. This will result in previous versions of the report to be overwritten.
For example • PUB_D_CODInterconnecotrUnits_EA,• PUB_D_CODInterconnecotrUnits_EA2 and • PUB_D_CODInterconnecotrUnits_WD1
will be copied to the Legacy Ftp site as • PUB_D_CODInterconnecotrUnits
25
Market Operator User Group Meeting25
SEM R2.0.0: Intra-Day TradingReport Timing and MPUD
At Participant request we have staggered the publication of some of the D+1 Public reports so there is sufficient time for the affected Participant to poll these from the FTP site.
Feedback on this proposal was requested from all Participants (via Market Helpdesk) and no objections were raised.
The MPUD (V1.3) was updated to reflect the changes and was issued on15/05/2012.
Changes were implemented in the CMS in time for End-To-End phase of Market Trial.
Change Summary:• EA Reports will be published at 9:00am TD+1;• EA2 Reports will be published at 10:45am TD+1; and• WD1 Reports will be published at 13:55pm TD+1.
• Notes: • T&SC Obligations specify these reports must be published by 14:00 TD+1. • Affects Public reports only.

SEM R2.0.0: Intra-Day TradingLegacy FTP Site
Participants are reminded that the Legacy FTP site should not be utilised for business critical data provision. Participants who continue to use this facility run the risk of data loss.
The Legacy FTP site will be decommissioned by SEMO at some point in the
future – consultation on timeline will be held with the industry.
In preparation for decommissioning, Participants should switch focus to the SEMO website data facility or utilise the MPI in the Central Market Systems for “Public Data” provisioning.

Questions and Answers 12:15
Treatment of Firm Access Quantities in the SEM
Firm Access Quantity
“… the quantity of Output that a Generator Unit has firm rights under a Connection Agreement to be able to export onto the system at the point of Connection” - T&SC Glossary;
Connection is generally represented in the SEM as the Trading Site;
Trading Site is group of generators that are “…covered by a single Connection Agreement…” - T&SC Glossary; “…are located on a Contiguous Site…” - T&SC Glossary;
In the SEM, Firm Access Quantity is recorded against the Trading Site;
55
Market Operator User Group Meeting55
Treatment of Firm Access Quantities in the SEM
Firm Access Quantity
Connection offered up to contracted Maximum Export Capacity (MEC);
If not fully firm, then Firm Access Quantity applied;
Where a unit is fully firm to its MEC but has higher installed capacity, the quantity greater than the MEC is non-firm in the SEM;
In the SEM, FAQ of a Trading Side = Sum(Registered Capacity) – Sum(Non-Firm Capacity);
56
Market Operator User Group Meeting56
Treatment of Firm Access Quantities in the SEM
Firm Access Quantity
Maximum Generator Capacity = Registered Capacity
Registered Firm Capacity is a derived quantity based on a pro-rata of the FAQ for the site across the installed units on the site – not used in the SEM
Non-Firm Capacity is derived based on Maximum Generator Capacity – Registered Firm Capacity
57
Market Operator User Group Meeting57
Treatment of Firm Access Quantities in the SEM
How FAQ is used
Used in the calculation of Actual Availability;
Applies to all settlement classes (PPMG, PPTG and VPTG);
Not used in the calculation of Eligible Availability for Capacity Payment;
“The Market Operator shall calculate values of Availability Profile …without consideration of access limitations.” – T&SC, 4.54;
58
Market Operator User Group Meeting58
Treatment of Firm Access Quantities in the SEM
How FAQ is used
The Generator Unit values in the Market Participant Interface are not used in these calculations;
Actual Availability is calculated dynamically for each Trading Period for each Generator Unit where the Trading Site is not fully firm;
Calculation takes account of Availability Profile of each Generator Unit on the Trading Site; The Firm Access Quantity of the Trading Site; The Dispatch Quantity of each of the Generator Units on the Site; The on site demand, where registered explicitly (Trading Site Supplier Unit);
59
Market Operator User Group Meeting59
Treatment of Firm Access Quantities in the SEM
How FAQ is used
Step 1:
This takes the Firm Access Quantity for the site, …adds any metered demand on site (served behind the connection point), …and allocates the FAQ to each unit, pro-rata to their Availability Profile
60
Market Operator User Group Meeting60
Treatment of Firm Access Quantities in the SEM
How FAQ is used
Step 2:
This calculates an Access Quantity for each Generator on the Trading Site …which is the smaller of the Availability Profile, …and the unit Firm Access Quantity. Note, that the unit Firm Access Quantity here is compared against the Dispatch
Quantity. Therefore, if the unit is dispatched by the TSO above its allocated Firm Access Quantity, the higher value is used.
61
Market Operator User Group Meeting61
Treatment of Firm Access Quantities in the SEM
How FAQ is used
Step 3:
This calculates an Access Quantity for the Trading Site …which is the smaller of the summed Availability Profile of all Generators, …and the Trading Site Firm Access Quantity, including any demand served
behind the connection point. Note, that the Trading Site Firm Access Quantity here is compared against the
summed Dispatch Quantities for all units on the site. Therefore, if the combined dispatch for the site is above its allocated Firm Access Quantity, the higher value is used.

Step 4:
This calculates an Actual Availability for each Generator on the Trading Site …where the units have been dispatched to their total Access Quantity, then this
is used, …where the units have been dispatched below their Access Quantity, again the
Access Quantity is used (because this expression calculates to zero), …where the units have been dispatched above their aggregate Access Quantity,
their Access Quantity is increased by the difference, pro-rata across the site.

Treatment of Firm Access Quantities in the SEM
How it impacts
For Predictable Price Makers, availability for use in the determination of market schedules is limited by Firm Access Quantity;
Modification 43_10 – introduces the Actual Availability value for Variable Price Takers when constrained down;
This means MSQ for VPTs will be limited by their Firm Access Quantity;
Modification becomes effective from next software release (SEM R 2.0);

Next steps
SEMO and EirGrid TSO have completed a review of values recorded in the SEM registration system;
Have reviewed values of – Firm Access Quantity for each Trading Site; Maximum Generator Capacity (Registered Capacity) for each Generator Unit; Registered Firm Capacity*; Non-Firm Capacity*;
Discrepancies have been identified in the set up of some Sites/Units;
We will be contacting affected Participants with details of data as recorded in our system and what is understood to be the correct data;
We will ask affected Participants to confirm the correct data;
