Introduction

This presentation aims to provide an overview of the process for Class change specifically the reconciliation and Check Read processes.

The presentation also covers scenarios where there is a Shipper Transfer and Class change combined.

Where a combined change of Shipper and Class change is associated with DRE/AMR equipment the focus is around apportioning the drift following a Check Read.

19

Why have a Check Read

Check Reads are required where equipment (AMR) is installed that derives the reads from the meter.

The Check Read identifies where the meter and the equipment are not synchronised and will detect any drift between the meter and the equipment. Any drift is then apportioned across the relevant period.

D: Effective date of the Class Change

22

Where DRE/AMR is installed for Class 2, 3 & 4 the kit is not changed on a Class change only event.

For a change in Class an Actual read is required to close out the outgoing Class.

The Actual Read provided for the effective date of the Class change will not be subject to the read tolerance validations only standard asset validation (serial number, dials and units etc.)

This is because the read may not follow on from the previous read due to the difference between the on-site reading and the derivable reads.

On Class Change only event the Check Read will reconcile back to the previous Check Read or AMR/DRE Installation Read.

When AMR/DRE equipment is installed the first Check Read received will reconcile back to the previous Check Read or Installation Read.

General Principles

23

There are 3 steps for energy allocation/reconciliation for Class 3 and 4 Supply Meter Points where AMR equipment is installed

a) Daily Allocations are based on the Demand Estimation Formula.b) An Actual Read received will trigger reconciliations.

Daily for Class 3 Periodic for Class 4

c) Following receipt of a Check Read reconciliation will be triggered back to the previous Check Read

In the cases of a Shipper Transfer this will be the opening read.

Where AMR/DRE is fitted on a Class 3 or 4 Reconciliation will be processed first followed by the Check Read Reconciliation (apportion the drift across the period).

For Class 1 and 2 any replaced meter readings received outside of close-out will trigger Reconciliation.

General Principles - Reconciliation

24

General Principles – Shipper Transfer

For Class 1 and 2, any reads received following a Shipper Transfer that fail validation will generate an Estimated Read. On receipt of a valid actual read the Estimated Reads will be

re-calculated (better estimates) back to the Shipper Transfer/Class change day.

If the Check Read is not provided for the Class change date for a Shipper Transfer within the UNC timescales then an Estimate Read will be calculated and treated as a Check Read.

Class 2 within GFD+5 Class 3 & 4 within Month+10

For a Shipper Transfer where the outgoing Class is Class 1 or 2 the D-1 volume will be estimated for Allocation purposes, either using D-7 or AQ/365.

This is to ensure that the drift is allocated to the correct period (previous Check Read) rather than the total drift allocated to the day before the Class change

On Shipper Transfer where AMR/DRE equipment is fitted the Opening Read received will be treated as a Check Read and therefore will trigger Reconciliation back

to the last Check Read. This will close out the position for the Outgoing Shipper.

Risk Summary Impact Date Mitigation

Industry readiness: Risk that there is a varied understanding within stakeholder organisations of Nexus requirements due to lack of or inconsistent attendance at industry forums.

June 2015

Xoserve’s programme of industry engagement at all levels aims to level-set understanding. Terms of Reference in UKLIEF will avoid re-working topics agreed through PNUNC.

File Formats: There is a risk that any changes to file formats as a result of the UKLC approval process (formal consultation and reps) may impact on the ability of the industry to deliver by Oct 2015 due to design re-work

Nov2014

Draft file formats released in August to give early sight and UKLP Engagement Day set up to focus on file formats in the context of business processes.

Market Testing: Risk that Market Trials is insufficient in length, too late within the programme, and participants may not be ready in time to take part.

A presentation to:

iGT Shipper Workgroup 3rd November 2014UNC Nexus Workgroup 4th November 2014

See also the iGT single service provision data preparation and migration overview report published on the Joint Office website

46


To move to the iGT Single Service provision arrangements a number of activities are required

At some point the iGT systems must close There are then a number of activities to prepare arrangements for the UK

Link system – particularly around finalising the data for migration. The UK Link system will then open A period of time is required to prepare the UK Link system. During this

time supply point register updates and supply point administration communications cannot be made.

This does not mean that events cannot occur on these days or that updates cannot be made that are effective on these days.

47


Six non-effective days for the purpose of supply point register (SPR) and supply point administration (SPA) communications

This means that SPR and SPA communications cannot be sent to an iGT on these days

The six days are September 25,26,27,28,29,30 The last day a Shipper can send a SPR or SPA

communication to the iGT is Thursday 24th September From 1st October Shippers will send SPR and SPA

communications to the UK Link system

48


Why six days are needed Working back from 1st October 05:00 hrs

The data to support Gemini processes (balancing etc) needs to be in Gemini for the start of day D-2. D is 1st October, D-2 is 29th September 06:00

This means the data is loaded to Gemini on 28th September The source of the Gemini data is the Data Preparation Database The Data Preparation Database must have a final position on 28th September

circa 13:00hrs On 27th the data will be subject to check and re-check, no new data will be

added to the Data Preparation Database on this day. (The final shipper portfolio will be issued from this closed-out position)

The last processing of data on the Data Preparation Database is the 26th September

The last date iGTs can submit data is 25th September Therefore the last day the iGT can accept files for processing for them prepare

the final data for submission to Xoserve is 24th September

49


What are the implications of this? The “faster switching” timescales, which create the minimum period

for a transfer (14 calendar days starting from the day after the confirmation file is received), will not apply for the six days

To effect a change of shipper event on 9, 10, 11, 12, 13, 14 October the confirmation file must be submitted to the iGT by 24 September

Any updates to the SPR e.g. asset update, meter reading etc that would ordinarily be submitted between 25 and 30 September will need to be submitted to Xoserve from 1st October using the new file formats.

There is no opportunity to “back-date” files. All files processed from 1st October will be processed and validated against the receipt date of the file

50


Confirmation of SPA and SPR files processed pre and post cut-over SPA events that start in the iGT system and end in UK Link will be

migrated with no impact to the event. However, Shippers need to be aware that apparent unsolicited files will be received.

The effective date of any SPR updates processed after 1st October will be maintained e.g. a meter exchange on 25th September will be recorded as having happened on the 25th September
