Matters From Previous HWG - Resolved
NIE to issue message 303R when a CoS read provided on message 010 or 210 is rejected CoS Estimate Is Not Allowed Last Actual Read Date is included on messages 102 and 102P This field can be used to determine if an estimate would not be allowed 3 Private and Confidential

Matters From Previous HWG – Carried Forward
NIE MPRN Website Data Publication Legal Review CER Consultation & CoP on Objection & Debt EAC effective date available in aggregation audit trail – to Dec 1st ESB and NIE will investigate possible differences in the check digit algorithm and report back De-energisation CoP review – to detailed design Review of response messages when a CoS estimate is not possible Review of CoS cancellation time-out reasons Extension of CoS customer read window to D-5 (IGG status) 4 Private and Confidential

3rd Package Introduction Main provisions of the Third Energy Package
Retail market amendments

3rd Package Third Package: main provisions Retail market measures
Stronger powers for national regulators Effective unbundling of networks Regulatory Agency at EU level (ACER) Cooperation of network operators (ENTSO)

3rd Package New provisions for the operation of the retail market:
Published rules on the roles and responsibilities of all market players Information for consumers: European Energy Consumer checklist New deadlines on switching, 3 weeks, and receipt of final bill, 6 weeks Consumer access to consumption data in sufficient time periods Implementation of Smart Metering .Promotion of Smart Grids

3rd Package Uncertainty on 3rd package:
Only the directive is published. We still need the EU Commission Guidance Document. Governments use that to draft legislation. We comply with the legislation.

Change of Tenancy / Legal Entity Required Data and Readings
CoT / CoLE may be future dated or past dated CoT / CoLE and any readings will be dated at a provided, valid required date If there is no date provided, then the message receipt date will be used for both the CoT/CoLE and any estimates. Readings will be ignored If date is prior to the last DUoS bill date, then the message receipt date will be used for the CoT/CoLE but any readings are ignored and an estimate is used in RoI for non MD sites below 30kVA NIE propose to introduce a check against dates that are significantly into the future Readings may be provided on message 016 Readings are ignored for interval, MD or unmetered sites Readings are ignored on a future dated CoT/CoLE Readings accepted will be advised using message 300 Readings rejected will be advised using message 303R This does not reject the CoLE/CoT and does not apply to future dated readings Where readings are invalid or no readings are provided: ESB will estimate readings, provided DUoS billing has not occurred, and provide these on message 300.

Agreements and Exceptions
Supplier exceptions to proposals for changes to NI processes 63 Private and Confidential

Data Processing – Comment Requested
Will be discussed in detail on December 1st To align with ESB, NIE provisionally propose removal of usage factors at register level ESB provide this data at Meter Point/Timeslot level but not Register level Introduction at register level is not a feasible option using SAP ESB have a working practice (005) to address issues that may arise NIE currently provide this data at Meter Point/Timeslot and Register level This is relevant only where multiple instance of same timeslot Multiple instances of same timeslot are relatively rare Note that estimated consumption will continue to be provided on message 320 at register level to help in first bill calculation How do Suppliers use AUF and EUF at Register level in NI? What would be the impact of removal in NI? 64 Private and Confidential

Data Aggregation – Comments Requested
Aggregation files ESB provide analysed aggregation data on messages 591 (NQH import), 595 (QH import), 598 (non-participant generator) NIE provide this data through a secure server How do Suppliers use this data What would be the impact of removal If the data is required, should messages 591, 595 and 598 be used in NI Messages 594 provides analysed data on distribution connected participant generators which may be sent to associated Suppliers Suppliers may receive such data where generator does not have MPCC Do any Suppliers need this data through a market message in NI Messages 596 and 597 provide copies of SU and participant GU aggregated data sent to SMO Message 597 (GU) available to Suppliers under similar arrangement to 594 Do Suppliers need this data to be provided through either or both of these market messages in NI NI alternative to market messages is to remain with the secure server approach DUoS group and MCC breakdown will be lost if market messaging is used Will be discussed in detail on December 1st 65 Private and Confidential

Technical Workgroup NIE intend to provide functionality whereby A Supplier will be able to access an NIE web-site to view messages they have sent to NIE and which NIE have received a Supplier will be able to view only those messages that have completed processing and were successful. A Supplier will be able to access an NIE web-site to view messages NIE have sent to them NIE and ESB are continuing to review options to enable a Supplier with MPCC/EMMA or equivalent to send messages on behalf of another Supplier (e.g. a retailer) that does not have MPCC/EMMA or equivalent 66 Private and Confidential

Update on Harmonisation Baseline and Change Control
Retail Market Harmonisation Working Group 4 Update on Harmonisation Baseline and Change Control NIAUR Offices, Belfast 16 November 2009

An update on current proposals…
What is the Harmonisation Baseline? How will it be authorised? How will change control work?

What is the Harmonisation Baseline?
Formal record of all changes to schema and processes needed within both jurisdictions to achieve harmonisation Those elements common to both jurisdictions, or relating solely to NI, will need to be documented, authorised and baselined by early January 2010, in order to form part of the contract documentation for the Enduring Solution Those elements relating solely to RoI can be authorised after this date, provided that such authorisation does not change any aspects of documentation relating to NI Authorisation will initially be through the HSG Once authorised, all documentation will need to be placed under strict change control

Contents of the Harmonisation Baseline
What is included in the Harmonisation Baseline: Message Schema spreadsheet Message Guides Agreed Changes documentation summarising agreed changes to Market Procedures in both jurisdictions What contributes to the Harmonisation Baseline: HWG presentations and minutes What will become part of the Harmonisation Baseline in due course: Updated Market Procedures (both jurisdictions) Updated Operational Framework (NI)

Genesis of Harmonisation Documentation
Part of Harmonisation Baseline; under change control once authorised Message Schema ESB / NIE workshop documentation Will become part of Harmonisation Baseline; under change control once authorised HWG presentations / minutes Order of production Message Guides Authorised document; not under HSG change control Changes to Market Procedures Contributory document NI Market Procedures* / Operational Framework * Position on RoI Market Procedures tbc

Baseline Documentation (1)
Message Schema spreadsheets Excel files setting out content and format of all messages Highlight any changes needed in either / both jurisdictions Reviewed and approved by HWG as part of HWG presentations Will be held on RMDS website Message Guides Set out message content and structure, and message validation (which may vary by jurisdiction) Separate sets of documentation NI and RoI ESB production for RoI as-is situation in hand To be passed to NIE as a basis for NI version early Dec – to be completed by christmas Further ESB updates to reflect RoI to-be situation can be completed during early 2010

Baseline Documentation (2)
Agreed Changes to Market Procedures Separate documents for each jurisdiction, summarising changes which will be made to each individual market procedure Possibility of no changes, and therefore no documentation, for RoI In NI, documentation will serve two purposes: An interim record of changes prior to update of Market Procedures next year (see next slide) An aide-memoire for Enduring Solution (ES) bidders to help understand the impact of harmonisation on their proposals NIE will prepare this document (as part of ES project) by end December Document needs to be included in Harmonisation Baseline (and therefore authorised and change controlled) as bidders may rely on its information in preparing their proposals for ES delivery RoI position tbc (depends on need for such a document)

Other important documentation
HWG presentations Essential summary of all harmonisation-driven changes to market processes and schema in both jurisdictions Walked through in detail at HWG meetings, with full opportunity for Supplier input, comment and update Approved by HWG at relevant meeting Minutes of HWG meeting form record of approval NI Market Procedures Will need to be fully updated to reflect impact of harmonisation Enduring Solution design process may also drive further detailed change Work to be completed during 2010 Agreed Changes document (see previous slide) will need to be read in conjunction with existing Market Procedures in the meantime NI Operational Framework Draft developed as basis for Enduring Solution project, published September 2009 To be updated and authorised in parallel to Market Procedures (above)

Document Authorisation – Harmonisation Baseline
HSG is responsible for authorising the Harmonisation Baseline (Message Schema, Message Guides and Agreed Changes to Market Procedures) HSG meeting on 26 November to agree how the required authorisations will be completed: HSG authorisation likely to be through presentation of evidence of internal review (NIE / ESB as appropriate), and clear recommendations from HWG For NI-related material, authorisation needs to be completed in time for inclusion in NIE procurement documentation end January 2010 Message guides (and Agreed Changes documentation, if any) for ROI subject to later running process and likely to be authorised early 2010

Document Authorisation – Other Documentation
NI Market Procedures and Operational Framework: All activities to update, review and authorise these documents to be covered as part of Enduring Solution Stage 3 planning Position on ROI market procedures tbc

Future Evolution of the Harmonisation Baseline
Baselined market processes (Jan 2010) Timeline not to scale Start of ES Design Phase Start of ES Test Cycle Start of Market Test Start of ES Build Phase Go Live (c. +24 months) ES Delivery Timeline Contract let ES Design ES Build ES Test Market Test E: Updated Harmonisation Baseline agreed G: All participants ready to enter market test B: Harmonisation Baseline agreed A C & D F H: ESB Schema Drop I: ESB Schema Drop

Approach to Change Control
Proposals for change control procedures for the Harmonisation Baseline currently under development Outline proposals to be presented to HSG 26th November; detailed proposals (+ authorisation of these) to HSG 18th December Proposals need to be in place early January 2010 to manage the approved Harmonisation Baseline Some principles: Change control procedure for Harmonisation Baseline likely to be based on the existing RMDS procedure Will only be used for changes which impact on the Harmonisation Baseline – all other jurisdiction-specific changes will continue to go through existing channels (RMDS in RoI, CDA in NI) Procedure will need to involve all market participants … … including the Enduring Solution delivery project, recognising its particular scope / timescales / pace of delivery

Any Other Business 79 Private and Confidential

Comments on Todays Proposals
To be forwarded to By Friday November 20th 2009 for Customer and MP Data By Monday November 23rd 2009 for DP/DA usage factors and aggregation files 80 Private and Confidential

Next Meetings Tuesday December 1st, 11am to 3pm At CER offices, Tallaght Proposal agreement on customer and meter point characteristics data Presentation Data Processing & Aggregation Unmetered Supplies DUoS Billing Message 311 Market Message Infrastructure 81 Private and Confidential
