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 2006. 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.

ESB Networks AIP Programme : 4. Issues – SLA for Actual/Estimate Flag

SLA for Actual/Estimate Flag on Agregation messages

All SEM settlement statements have the requirement to indicate if the settlement data is estimated or not. To facilitate this there is a field called the Reading Data Status field on the 590, 596 and 597 messages messages, and this is per 30 minute interval.

The percentage value to be used to determine whether the flag is set to actual or estimate needs to be agreed

For Unscripted Market Trials , these were set at

90% Indicative D+195% Initial D+499% M+4 RA99.5% M+13 RA98% Ad-Hoc

and we are looking for confirmation of values for go live

25

ESB Networks AIP Programme : 4. Issues – SLA for Actual/Estimate Flag …contd

Some additional info taken from Aggregation Briefing Paper

SIMDRACs has defined the following definition of ‘Estimated’:

• For each Supplier Unit aggregation D+1, D+4, M+4, M+13, there will be service level agreements for the different percentages of estimated data. Service level targets for meter readings are to be agreed , and if met then the Supplier Units aggregated data will be marked with an actual flag (1), otherwise an Estimated flag (0), per half hourly interval

• Interval meter data only and not NQH data to be considered in arriving at the estimated or actual flag.

The SIMDRACS rules for determining whether an aggregation of meter readings was estimated or actual is based on the concept that there is only one meter reading to be considered per MPRN. This may not be the case where there is Generation on the site, particularly where there is splitting of the generation between several suppliers outside of the market.

• Therefore, when calculating the value of this flag the actual/estimated value will be determined only from import meters• Also, where two 15 minute intervals are amalgamated together to a 30 minute trading period, if either or both of the 15-minute meter reading is an estimate then the 30 minute trading period metered volume will be considered as an estimate.

26

ESB Networks AIP Programme : 4. Issues – MPCC ver 14.0

• Release 14.0 of the MPCC and Webforms issued to all Retail Market Participants by CD on October 10th 2007

• Background

During a planned test of all market messages, a problem was found with message 114 and 330 – neither of which are being amended for AIP.

Impact of problem was that 114 and 330 would fail in certain circumstances

• Action Taken

Correction was made to these 2 market messages and was included in release 14.0 which was issued to all Retail Market Participants.

These are being tested with 2 Retail Market Participants in the Unscripted Market Trials environment

• Please install release 14.0 on your test MPCC if you have not already done so

27

ESB Networks AIP Programme : 4. Issues – MPCC ver 14.0…..contd

Additional Comments

• As already advised, this was a simple defect

• Testing picked up the defect – would have been picked up earlier except that this element of testing was running a little late

• An additional step has been included in the process for future releases of Schema to avoid a reoccurrence

• Again, apologies for any inconvenience caused
