Whilst we try to close

as much issues as

possible, can we

consider to utilise time

until 20th March to

correct AQ values via

data update script / tool

Formula Year AQ

is effective from 1st

April and used for

transportation

charges

Note: For any meter points where AQ

has not been corrected, any AQ

reporting issued to Networks will show

the incorrect AQ value. A corrected

aggregate ‘ball-park’ value by LDZ will

be issued to relevant networks on or

soon after the 1st December.

Plan/Time

Extraordinary Change Management Committee on 23rd of July approved the split delivery of Release 3 scope into 13 CRs on 2nd of

November and XRN 4454 to be delivered on 1st February 2019

• The progress against each track is as below:-

• Track 1 (13 Changes) – MT ongoing and on track to complete latest by w/c 08th October. Regression testing tracking slightly

behind plan , no impact envisaged to milestones for all changes except XRN 4534 which is RED due to issues found (see

below issue section), IDR planning and preparation underway.

• Track 2 (XRN 4454) – System Testing is now underway with some delays within plan due to complexity of testing – revised

plan now in place along with a synergised Acceptance Testing.

• Issue XRN 4534 : a number of observations on XRN 4534 as part of Regression suite– these issues have dependency on Production

teams to understand and work up options; Issues are being worked through with Xoserve Operations team to understand root cause

and solutions – This places XRN 4534 in RED status and at risk for Go Live on 2nd November.

• Clear resolution plan on XRN 4534 is being prioritised and outcome of this resolution plan will be communicated to all by 10th October

ChMC meeting.

• The Market Trials progress update available on Xoserve website, MT on track to complete as per planned timeframes, MT Closedown

w/c 08th October

• Implementation approach and file level transition plan published to participants. Implementation plan approval sought at E- ChMC on 2nd

October. Follow-on Track 1 training sessions are planned in October before Go-Live.

• Cadent MT registration to open shortly, parties are requested to register interest for Cadent MT starting 19th November. MT information

Inc. high level scenarios to be presented at next DSG onwards.

Risks and

Issues

• Issue against XRN 4534 places its delivery at risk for 2nd November Go Live – resolution being prioritised within Xoserve Project and

Production teams.

• Go Live date dependent on close management of parallelism in plan (this is being managed)

• Complete All System and Acceptance Testing on time to ensure Cadent MT entry on time

Cost • Full Delivery costs approved at ChMC in April 2018. Revision expected to accommodate XRN 4454 delivery date (ongoing discussions)

Resources • Greater resource needed for XRN4454 (both technical & SME) for fulfilling the need for extended track 2. Daily tracking of plan in place

to ensure progressing to revised timelines and additional resource support to deliver XRN 4454

• SME resource requirements for Build, ST and AT phases is being managed weekly with internal Xoserve teams.

6. June 2019 Release Scope

June 19 Headlines

Of the 12 changes originally allocated to June 2019:

• 9 changes have completed ‘capture’ phase

• 6 changes are out for solution option review

• 1 change with Xoserve to complete HLSOIA (XRN4690)

• 2 changes have had the preferred solution options agreed (XRN4670, 4687)

• A further 3 changes (XRNs 4642, 4645 & 4679) are now proposed for November 2019.

• As the preferred solution option for each change needs to be agreed prior to being formally assigned to a

June 19 release, there is a tight timeframe to ensure that all changes are in a position to be agreed in

October 10th ChMC.

• An extraordinary ChMC may also be required, following October’s ChMC, to approve the EQR for the

progression of Design.

© 2017 Wipro wipro.com confidential 42

Change Overview

XRN4690 – Actual read following estimated transfer read calculating AQ of 1

Change was raised to look at options surrounding mitigating the AQ’s of 1 as a result of an lower Cyclic Actual Read

being submitted following an Estimated Transfer Read causing a negative consumption. DSG/ChCM confirmed 2

solution options to move forward with. 1) Roll over previous AQ where an AQ of 1 is being calculated as a result of

actual following estimated transfer reading (to be progressed via XRN4690) 2) Re-estimate Estimated Transfer Read

following a Cyclic Actual Read (to be progressed under a separate XRN)

Delivery of the agreed solution can be delivered via a number of ways, each variant are outlined and impact assessed in

the up-coming slides.

Solution Options

Roll over previous AQ where an AQ of 1 is being calculated as a result of actual following estimated transfer reading

Identification of an estimated transfer scenario in the AQ Calculation process (by bringing in the read type etc) to target only the negative consumption following estimated transfer to roll over the AQ.

Where either the First (oldest) variance period considered in the AQ Calculation process is a negative then roll over the existing AQ (by rejecting the calc and sending appropriate rejection code in NRL)

1 - Roll over previous AQ where an AQ of 1 is being calculated as a result of actual following

estimated transfer reading

With the changes to be implemented, when an actual read is submitted following an estimated transfer reading, the

system will load the reads successfully. However if the Actual reading is less than the estimated reading there will be

negative consumption. if any negative consumption is there in the AQ period then AQ will not be any re-calculated in the

system and will continue the previous AQ. In addition to this, the NRL file will contain the rejection code CPN00321

(Negative Consumption during metered period. AQ not calculated) for the records in it.

With the changes to be implemented, any read received in the system resulting into a negative consumption in the first

variance considered for AQ calc, the AQ will not get recalculated and the rollover will take place. Any further read

received in the system with an outcome as a positive consumption being seen in the first variance will trigger the AQ

recalculation.

In addition to this, the NRL file can contain a new rejection code outlining the reason for rejection or use an existing.

4670 - Reject a Replacement Read, where the read provided is identical

to that already held in UK Link for the same read date

For DSG’s information only, Xoserve issued this change within a Change Pack

on 17th September (2076.2 – RJ – RH) for industry consultation on the solution

options

Please note that this was a reissue of 2074.3 – RJ – RH

Xoserve received five responses from the industry:

Four responses approved Xoserve’s and DSG’s preferred solution option

(Option 2)

One rejected and suggested an alternative solution (Option 1)

A description of the change and the solution options are on the next slide

This will be taken to Change Managers Committee on 10th October for

approval of a solution option


Change Overview and Solution Options

XRN4670 – Read Replacement creating unnecessary exceptions

Shippers are currently submitting replacement readings, with a read which is identical to the previously submitted read

recorded in UK Link for the same read date. Current validation and business processes do not consider this scenario

and therefore as a result is leading to an increase in the number of exceptions received and manual intervention taken

to resolve. Where a replacement reading is submitted to ISU (via NDM read files) that has the same read value and

read date it creates a zero billable consumption, something that at present is not expected and therefore generates a

MN09 exception to be looked at. The current processing of the exception requires a manual consumption adjustment

to be completed by the business ops team for an adjustment to be released and the read to be re-processed.

Solution Options

Reject “duplicate” replacement reads and provide a new rejection code/reason

Reject “duplicate” replacement reads and provide an existing rejection code/reason

Amend SAP ISU to process the replacement read but the zero consumption is not processed

Amend SAP ISU to process the replacement read with the zero consumption being processed

12a. Market Intelligence Service (MIS) /JMDG Overview

MIS Origins

Ofgem set out 4 reform packages:

1. Do nothing

2. Enhance existing

3. CSS

4. CSS and MIS

As a result of the consultation Ofgem refined option 2 and the new option became 2A, and

determined that the industry was best placed to develop and fund the MIS services

Ofgem then asked Xoserve and Gemserv to take forward the MIS initiative

MIS is a suite of Data Products and services that support improvement in the reliability of

switching, and enhanced consumer experience

RP0 RP1 RP2 RP3 No system or process changes. No Improvement to reliable switching. 21 day switch.

Use existing systems. Address matching to improve reliability. Key Process changes (harmonised where possible) to deliver 3 to 7 day switch.

New central switching service (core data). Enduring reliability improvement to data quality. Harmonised and simplified next day switching process.

New central switching service and market intelligence services. Enduring reliability improvement, and improved access to broader range of switching data. Harmonised and simplified next day switching process.

MIS Governance

Industry Consultation

• Open Letter published 4th January

• The Open Letter was the first stage of an ongoing consultation approach

• Over 20 responses: range of stakeholders: suppliers, networks, metering

organisations, water/business customer, Citizens Advice, medium/large suppliers, as

well as from Alt Han Co

• Wide spread support

• Broad consensus for an unconstrained approach

• Initial priorities focusing on extending the API service to energy suppliers and support

for Ofgem’s Faster and More Reliable Switching Programme (switching programme)

• Over 55 Use Cases identified, more Use Cases are evolving

12b. Defect 838 RGMA on Transfer Date (AML Impacting)

Story so far…

Defect 838 was raised to look into issues faced when an RGMA update is

received for an effective date that is D+1 of the Shipper Transfer Effective

Date and the Transfer Effective Read is then being replaced

Reconciliation issues are being experienced that cannot be processed

correctly and therefore being excluded from the amendment invoice

This defect (and exclusions) are in scope of the AML Taskforce so has

been given a high priority to resolve

DSG Members are asked to review the upcoming slides and provide input

on potential solutions that can be moved forward to resolve the defect

(enduring solution)

Please also consider the exclusions that are pending (solution may

require an alternative fix)

A number of scenarios have been identified that would need to be

considered

Considerations (how the system works)

3. Once D+10 has passed we will estimate a Transfer Read as per normal

NDM logic (RGMA read is not used in any capacity for Transfer Read

processing)

D-5 D+5

Shipper Transfer Effective Date

Transfer Read Window

2. If an RGMA comes in between D+6 to D+10 (effective date can be back

to D+1) then we will use the RGMA read (FINX) in calculating a

estimated Transfer read

1. If an RGMA comes in between D+1 to D+5 then the RGMA read (FINX)

will be used as the Transfer Read (but loaded as an estimate)

Considerations

In all 3 of the scenarios on the previous slide, the RGMA Effective Date

can be at D+1 of the Transfer Effective Date

From our interpretation of UNC (M4.2.10), we are able to reject an

“Agreed Opening Meter Reading” (5.13.12) where an RGMA read is

received via UPD (Meter Information Update Notification) and has been

used as the transfer read or if it has been used to estimate an opening

transfer read

UNC is silent on the use of JOB (Meter Information Notification) flows in

the same way

This issue is only being experienced where a replacement transfer

reading is being received (first time Reconciliation is accurate)

Approx. 260 have been affected by a replacement transfer reading

However there are approx. 164k potential sites where we have had an

RGMA at D+1 (not yet received a replacement reading)

Where UPD is estimated, the replacement transfer read could be greater

than the FINX and cause a negative consumption

Potential Solution Options

1. Reject the replacement transfer reading as per UNC

Could we also include Meter Information Notification (JOB) flows?

Solution would not resolve all scenarios covered

2. Reject replacement transfer reading only where we have an RGMA

present at D+1

Would need to look if this requires a UNC change

Shipper would need to submit Consumption Adjustment to reapportion

the consumption

3. Reject RGMA’s with effective date of D+1 of a Transfer Effective Date

(forcing the Shipper to submit them for D+2)

4. No system change, Shipper to submit a Consumption Adjustment to

account for the missing consumption, when required

Process needed for identification of sites where this is required

12c. Replacement/Insertion Reads (a negative consumption

scenario)

Overview

As part of the data analysis relating to XRN4690 (Actual Read following

Estimated Transfer Read Calculating AQ of 1) it was identified that

negative consumption is being seen in instances other than what is

specified within the CP

New scenarios are assumed to be rare (profiling in progress)

Solution has already been selected for XRN4690 however variants of this

solution are currently out for Impact Assessment

2 main scenarios are present

Inserting a read (before or after) an Estimated Transfer Read

Replacing a read (before or after) an Estimated Transfer Read

DSG Considerations

New variants of the preferred solution option for XRN4690 discussed in

the last DSG would not resolve these instances (however the original IA

would - Blanket rollover of AQ where negative is present)

Consideration needed to either…

Look into additional variant(s) for XRN4690 to include these scenarios

Progress with XRN4690 and work up solutions under a new CP

Do nothing (depending on numbers) live with the risk

13a. How can we improve the method by which we distribute Change

Packs?

Within Change Pack 2008.2 – ER – DA, we asked for the industry’s suggestions

on how we could improve the method by which we distribute Change Packs

We received some responses but there wasn’t consensus so we require further

discussions

Can DSG members discuss the suggestions we received so we can form some

actions for improving the method of distribution?
