COR3316: Implementation of UNC Modification 0451AV

UK Link Committee – May 2014

COR3316 Overview

[Modification 451AV has argued] that the Prepayment Profile [is different] from the standard domestic credit meter (EUC01) customer.

• [the illustrative profile developed during the Development Workgroup suggested that] during the winter period there is an over allocation of gas usage and during the summer period an under allocation of gas usage.

Xoserve is developing a solution to calculate a monthly reconciliation charge [which will invoice the difference between the EUC01 and the alternative profile].

Modification 451AV will end at UK Link Programme implementation when individual meter point reconciliation will start.

COR3316 Overview

• The meter points that will be subject to the reconciliation will be:

– Pre-Payment meters

• Users need take no action these will be subject to reconciliation based upon an extract from UK Link

– Smart meters operating in Pre-Payment mode

• Users need to provide an extract of their Smart Metering portfolio operating in Pre-Payment Mode. UK Link must also hold these as Smart Meters.

• UK Link Committee has approved the input format for this file

Reconciliation Invoicing

• The Prepayment Meters Supporting Information will be issued via the I’X against the .ADB invoice type issued via the .ADH invoice.

• The Supporting information will be issued in a new file format for prepayment meters .PPM.

• The new .PPM format will have 5 new record types: – P22– P23– P24– P25– P26

• The Prepayment Meters will utilise existing charge types: – ZRE– GRE– NRE

User Pays Charges

• The Supporting information for User Pays will be sent via the IX against the existing .ADW invoice type issued via the Adhoc (.ADH) invoice.

• The supporting information file sent will utilise an existing file .USP, but will require a new record type R21.

• There will be 2 new charge types created for .USP supporting information they are: – W19 - PPM ADJ ONGOING CHARGE CR– W20 - PPM ADJ ONGOING CHARGE DR

Implementation

• Implementation Date has yet to be defined

• File formats are provided to UK Link Committee in advance of establishing the Implementation Date to provide as much notice as possible

• UK Link Committee are asked to note:– This might not allow 6 months notice

• UK Link Committee are reminded of the December 2011 presentation regarding notice periods

– This is likely to be implemented outside of a UK Link Release

• UNC Modification 486 – Prepayment Profile for iGT Sites – Economies of scale assumed. This may impact delivery timescales.
