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.
• Class 1 and 2
• Class 3 and 4

Terms Used

• DRE Daily Read Equipment
• AMR Automatic Read Equipment
• GFD Gas Flow Day
• CR Check Read
• A Actual Read
• N Cyclic Read
• E Estimate Read
• D Effective date of the Class Change

22
General Principles

• 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.

23
General Principles - Reconciliation

• There are 3 steps for energy allocation/reconcilia
  tion for Class 3 and 4 Supply Meter Points where
  AMR equipment is installed
• Daily Allocations are based on the Demand
  Estimation Formula.
• An Actual Read received will trigger
  reconciliations.
• Daily for Class 3
• Periodic for Class 4
• 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.

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 GFD5
• Class 3 4 within Month10
• 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.

raised via CMS for fault period between two reads.
Where a Corrector Exchange has been updated the
meter readings and previous check read will be
used to automatically reconcile the fault period.

The submission of RGMA ONJOB File to update a

Risks
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 Xoserves 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 Nov 2014 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. June 2015 Xoserve are investigating the feasibility of de-coupling Market Connectivity Testing and Market Trials.
Dependency Date Required Impact if missed Status
Industry participants to cleanse Settlement data by December 2014 Dec 2014 Output from the Testing phase may produce unexpected results due to uncleansed data.
Industry (Shipper) agreement on Shipper file formats through UKLC Nov 2014 The programme will continue build and testing activities at risk.
Industry Stakeholders to complete their internal system builds Jun 2014 Industry may not be able to fully participate in the Market Trials phase

• 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
iGT Single Service Provision non-effective days

• 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
iGT Single Service Provision non-effective days
to support cutover

• Why six days are needed
• Working back from 1st October 0500 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
  0600
• 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 1300hrs
• 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
iGT Single Service Provision non-effective days
to support cutover

• 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
iGT Single Service Provision non-effective days

• 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
