Update on Harmonisation Project


HWG 26 August 2010

Background

Following its acquisition by the Electricity Supply Board of Ireland (ESB), NIE now intend to proceed with a SAP-based architecture for the Enduring Solution.

Whilst the overall objectives of the project will remain unchanged, a Requirements Review is currently underway to develop the details of this approach.

This pack: Provides further details of the Requirements Review Provides a preliminary view of potential areas for further

harmonisation between the NI and RoI markets resulting from this change in approach

Sets out the timeline for the HRDS change control process through which any changes are considered by all market participants

Enduring Solution Implementation Plan – current


HWG 26 August 2010

NIE Requirements Review

Objectives include: To confirm impacts of adopting SAP for NIE RR activities must integrate into detailed design and delivery

timetable Intention to retain original ES timetable and avoid negative

impacts on suppliers Deliverables to include:

Revised contractor solution for NIE Revised detailed implementation plan

Timeline: Analysis and impacts to be completed September 2010 Thereafter, any market facing changes to progress through

change control


HWG 26 August 2010

Scope of Requirements Review

RR will consider differences in existing NIE and ESB Networks ways of operation (both processes and data)

Supplier facing processes Reflected in the Harmonisation Baseline agreed January 2010 Some enduring differences agreed at that time Any changes to the HB are subject to HRDS change control

procedures HRDS change control procedure includes supplier consultation and

HSG signoff Internal business processes

RR will also look at NIE business processes within the scope of the Enduring Solution

Any change to an internal business process which has a consequential knock on effect on a supplier facing process will be handled through HRDS (as above)

Changes which do not impact supplier facing processes (either directly or indirectly) will not go through HRDS

All changes (irrespective of source) will be subject to full project change control, including assessment of impact on time, cost and overall quality of solution


HWG 26 August 2010

Current Status

Workshops are underway as part of the Requirements Review to confirm impacts of SAP solution to NIE requirements

Whilst too early to provide definitive results, we expect that:

in the main - the existing ESB SAP solution and processes will be adopted with limited impact on the Harmonisation Baseline

any changes which impact the Harmonisation Baseline (including any opportunities for further harmonisation) will be advised to both HSG and HWG via the HRDS change control process

Certain differences, identified earlier at HSG, are likely to remain (and thus need changes to ESB SAP as implemented for NIE). Examples include:

• Technical differences – eg in meter config and technical data

• Regulatory differences – eg de-energisation of occupied properties

• Market differences – eg keypad metering

• Complex differences in business processes – eg meter read cycles

Impact of Current Plans on Harmonisation Baseline

November 2010

January 2010HB Version 1.0

- Baseline for Wipro contract- Includes RoI June 2010 release

(optionally) Summer 2010HB Version 1.1

- RoI changes only for Nov 2010 release- No impact on NI

November 2010HB Version 2.0

- Changes arising from ES Design- Other RoI changes as needed

2011 / first half 2012HB Version 2.x

- emergency changes in both jurisdictions only

Second half 2012HB Version 3.0

- Post ES Go Live release(s) for both jurisdictions

June 2010

November 2011

ESB Market Systems Releases

NIE Enduring Solution Release

May 2012

This is still needed as a stable baseline against which to sign off the ES design for NIE (due Dec 2010). HRDS change control must be exercised by then.


HWG 26 August 2010

Update on Technical Harmonisation

Following the decision to adopt ESB SAP IS(U) for NIE

SAP will be the common core technology North and South

It makes sense for both ESB and NIE to extend SAP further into

common messaging technology

Options have already been explored in RoI

On this basis we expect SAP PI to be implemented in both

jurisdictions


HWG 26 August 2010

Application of HRDS Change Control process Areas of potential change highlighted on following slides. However:

The list is a preliminary one for advisory purposes only, and is likely to change further

Precise details of many of these potential changes are still being developed

Proposed dates in the HRDS change control process:

HSG meeting 10 September 2010 – HSG briefed on potential changes

HWG meeting 12 October 2010 – DRs raised for all proposed changes

HSG meeting 26 October 2010 – HSG advised of proposed changes in DR pipeline

HWG meeting 18 November 2010 – Agreed changes recommended as an MCR

HSG meeting 2 December 2010 – HSG approve MCR for incorporation in Harmonisation Baseline and ES Baseline
