  1. AUG Query Responses 19th December 2013

  2. Overview • AUGE Guidelines require AUGE to report outcome of Query Process to UNCC • UNCC to consider AUGE recommendations • UNCC to endorse AUGE’s recommended course of action or vote unanimously to reject (see section 8 of the AUGE Guidelines for details) • Presentation covers 4 queries raised by British Gas on 18th November • Queries that require changes to the AUGS cannot be implemented for this AUG year as discussed at previous UNCC

  3. British Gas - Query 6 • Concerns iGT CSEP snapshots • British Gas queried why data was not being used from a particular year • Clarified that data was being used correctly although the use of grey to distinguish between different sets had been interpreted as not being used • Going forward will use a different colour to distinguish snapshots • Nearest classification is under 8.5 “Material change that can be implemented for final gas volumes and rates” – it does not require a change to the AUGS

  4. British Gas - Query 7 • Concerns the handling of Permanent and Temporary UG • British Gas believe that temporary UG is already accounted for by backbilling in the historical data • This is not the case, meter reads/consumptions do not have this backbilling applied and we do not use RbD data in the methodology • Examined different components of UG to confirm • e.g. unregistered sites, Xoserve do not get historic meter reads during period of non-registration, theft is dealt with separately etc. • Not really a new issue, has been through multiple consultations since Autumn 2011 • Query classed under 8.4(b) as “Requiring no action”

  5. British Gas - Query 8 • Concerns the inclusion of very large AQ’s in unregistered site calculations and skewing of temporary UG estimates • Previously limited data/evidence to show that ALL large AQ’s were revised down • Obtained further data from Xoserve and reviewed UNC treatment of large sites • Two elements to this issue • A) Large AQ’s that would require treatment under VLDMCs if they were real (UG becomes temporary) • B) Large AQ’s that need to be scaled differently to the current method of scaling since these can skew the adjustment for the wider population • Part A classed under 8.5 as “Material change that can be implemented for final gas volumes” – but does not require change to AUGS • Part B classed under 8.5 as “Material change that can be implemented for final gas volumes” – this does require a change to AUGS

  6. British Gas - Query 9 • Concerns partially consuming iGT CSEPS and that an adjustment should be applied as per the wider population • Similar issue to AQ>1 not consuming and AQ=1 consuming • CSEP EUC band issues (based on max AQ – skews population incorrectly) • Do not have information on part year consumption or WAALPS to correctly adjust • Magnitude of issue ~55-91GWh • Issue with vacant sites earlier in the year had similar impact and not deemed to be significant during UNCC discussions. • Query classified under 8.4(b) as “Requiring no action”.
