LTNA Sites and supplier liability for
DUoS charges
• Option of reducing MIC proposed as means of reducing liability
• Changes to Connection Agreement require written agreement of both parties
• Provision for using Variations Clause subject to direction from CER
• ESBN process will include
– Writing to customer advising of reduced nominal MIC
– MIC can be restored on request at no cost to customer
– On restoration, customer liable for full DUoS arrears as
ESBN reserved capacity at connection point
21 September 2011 5

LTNA Sites and supplier liability for
DUoS charges
Other issues
• DG5 customers don’t incur DUoS capacity charges and unaffected by MIC changes
• Option only available at DG6 and higher
• Option limited to cases where disconnection is not practical or cost of disconnection exceeds a threshold level
• Rule set required for situations where the process applies since any costs are ultimately carried by UoS customer
Next step is to discuss with Gaslink and develop proposals for consideration by CER

CoS Loss process
21 September 2011

• Change of Supplier Loss where PrePayPower has gained a customer under standard market processes
– Does not cover ‘Hardship’ meters where ESBN have installed the prepayment meter
• This is governed by WP19

• PrePayPower processes based upon facilitating seamless transfer for the customer within the standard market processes
• The meter is put into credit mode to ensure that the customer supply is not impacted.
• A reconciliation is done with for each customer
– Credit on the meter can be refunded
– Any charges outstanding can be billed

• MM110 received from MRSO
– Customer is contacted to confirm that they wish to transfer
– Customer is given a code to put the meter into credit mode – ‘ZZCode’

• MM105L arrives to confirm loss
• MM310 arrives confirming the read
– A reconciliation is carried out of the customer usage versus top ups

• The major issue that we have experienced is where our customer has contacted a new supplier to be told that they cannot move onto their supply as there is a prepayment meter in place
– As you can see from previous slides CoS can proceed under normal market processes
• Our customer services is available at 0818 233
331 to deal with specific customer queries

• Purpose of these slides is to clarify the process for how concurrent requests for prepayment installation and COS are handled
21 September 2011 31

• It is possible for a COS request to complete while a prepayment meter installation request is underway.
– Very rare
– Impact of Debt flagging
– Timing of Requests
– Supplier requesting prepayment installation would be aware of existence of a 110MM
• End result could be discrepancy between market systems and Liberty Client.
– Customer with old supplier in Liberty Client but new supplier in market systems.
21 September 2011 32

• If a COS is underway when Request for
Install received:
– Request for Install will be not be processed
– Requesting Supplier will be advised
– COS proceeds as normal
21 September 2011 33

• If COS commences subsequent to a Request for
Installation:
– Prepayment installation will proceed
– COS will proceed
• Given the customer category, highly likely to be debt flagged and result in cancellation
– Gaining Supplier will be notified by KMS of prepayment installation
– Gaining Supplier can then either:
• Retain customer (instruct KMS to initiate COS in Liberty
Client), or
• Cancel COS
21 September 2011 34

• What happens is no action is taken?
– Customer will continue to top up using their previous
Supplier’s account/card
– Customer will be registered to gaining Supplier in market systems
• Resolution?
– Cancellation of COS at this point by gaining Supplier will result in reconciliation in market systems
– Gaining Supplier can then re-request COS (including
KMS request)

Recipient ID in Message must match the physical Message recipient
21 September 2011 39

Recipient ID in Message must match the physical Message recipient
Background
Message routing in the new Tibco-based environment will require that the message contains information to identify the final physical recipient of the message. There are two scenarios in the current Market design where the RecipientID in the message header is not the final physical recipient viz 341/342 Messages that are sent to TSO and 342/594/597 Participant Generator Messages that are sent to a nominated Supplier under WP12.
Impact
1.
341/342 Messages that are sent to TSO: these will now carry a RecipientID of TSO (this used to contain the Registered Supplier / Generator’s identifier)
2.
342/594/597 Participant Generator Messages that are sent to a Supplier under WP12: these will now carry a RecipientID of the nominated Supplier (this used to contain the Generator’s identifier).
These changes are illustrated overleaf
Note: No other scenarios or messages are impacted.

 Active List Validation

Phased validation of the Active List in preparation for the 1st
Harmonised Market Release in June 2013 has now commenced

The Active List was circulated on 14th February 2012 for consideration

List contents now need to be validated by the Market, and subset of 7 MCRs from the Active List was presented at HWG today of which :
 All MCRs were previously approved at IGG
 Five MCRs have been re-versioned.
 Today’s IGG Workload
 Approval Requested for updated version of MCRs 87 & 1033
 Feedback from MPs Requested – MCR 130

IMPORTANT NOTE:
 The 331/332 messages that include the Exchange Meter Reference Number were always intended to have a dual role, that is, to carry details of both physical
(actual meter swops) and logical (metering reconfiguration) changes at the metered site
 To change this arrangement as proposed in this MCR would be a fundamental change to this part of the market design and possibly was not the intent of the original MCR
 If suppliers are interested in isolating physical meter exchanges (which appears to have been the main driver behind the MCR), then they can do so by examining a combination of “Meter Cat + Meter Serial No” on old and new meters which will identify this type of change.

 Classified as ROI Specific at HWG today
 Background:
 Approved at IGG on 18/10/2007
 ESB Networks has confirmed that incidences of this are very rare.
 Only occurs if NT removes meter from a site on an incorrect order type e.g.
O/H Service Alteration. This will issue MM332 with Meter Point Status E.
 Requested at Today’s Meeting:
 Information from Suppliers regarding the scale of this issue to determine if MCR is still required by Market to be retained on Active List for future implementation.

Notification of
Removal from
Active List
 Background:
MCR was developed to agree a new (initially automated but then manual) solution to enable a Supplier who is registering the export arrangement for a particular non participant generator to request the receipt of the meter details relating to the MPRN via a 331 message, either by:
 Completing Form 2, to be included in Working Practice 14, at the initial registration of the Supplier to the non-participant Generator
 Requesting via email
MCR 173, with updated WP 14, was approved at Conference Call of
01.04.2010 and implemented by MRSO. However, it remained on the Active
List of MCRs.
 MCR has now been removed from the Active List
