15. Harmonisation Working Group Registration Request 010 Meter Readings Data required to identify registers will differ as NI system does not support register type code

16. Harmonisation Working Group Registration issues #1 – CoS Estimates  CoS estimates are permitted in RoI  Will be permitted in NI when scheduled or customer reads are requested but are invalid or not available  Will not be permitted if there is no read history in last 12 months 16 Private and Confidential

17. Harmonisation Working Group Registration issues #2 – Required Date  Mandatory for NI CoS when not using a scheduled read  Can be omitted in RoI and interpreted ‘as soon as possible’  Minor differences in rules for specifying required date  Cooling off period for NI domestic customers (see #3 next slide)  Operational differences such as fieldwork lead times  ESB will infer a required date when it is not provided  Handling of Required Date when a Reading is Obtained  In RoI the CoS effective date will be set to the day after the reading date  In NI the required date is used provided the reading used is within 4 working days of the required date  Suppliers requested to comment on the following options 1.Harmonising on the RoI approach 2.Keeping the current, separate arrangement 3.Allowing the NI decision to be driven by lowest implementation cost  Depending on NIE systems decisions, options 1 & 2 may incur costs 17 Private and Confidential

18. Harmonisation Working Group Registration issues #3 – Cooling Off Period  Cooling off period is feature of NI market for domestic customers  Suppliers prefer a single customer contact  To facilitate this, it is proposed for the NI market only Required date must be at or after end of Cooling Off Period Suppliers may provide meter reading on messages 010 or 210 If provided on message 010 at registration –If Suppliers sets CoS estimate flag on NIE will create estimate based on this read at required date (unless a higher priority read available) –If CoS estimate flag is not set then can NIE use message 010 read at end of CoP or should message 210 be expected? If provided on message 210 following Cooling Off Period –NIE will use message 210 reading to facilitate CoS at read date  Retrospective CoS (at start of CoP) is an alternative possibility  Next slide discusses 18 Private and Confidential

19. Harmonisation Working Group Registration issues #3b – Cooling Off Period  Retrospective CoS (at start of CoP) requires consideration by Suppliers of three issues:  Processing of scheduled reads occurring within the CoP need to be agreed If a scheduled read is available can it be used in place of the message 010 read  NIE (and potentially Old Suppliers) would need to suppress or reverse messaging and billing for a period of 10 working days Accepting use of scheduled read as the CoS read would eliminate most of these issues  Initial aggregation for settlement will be against the Old Supplier at D+4 until end of cooling off period (D+10) Suppliers should consider whether this is acceptable  Retrospective CoS is not possible for keypad  Customer must call in to complete transfer  Keypad codes cannot be input retrospectively 19 Private and Confidential

22. Harmonisation Working Group New Connection Registration  New Connection Energisation  Registration is required for energisation of an NI domestic customer  Registration is not required for energisation of an RoI domestic customer  NIE propose to retain enduring solution rule because: Operational efficiency arises from meter installation as per Supplier request Enables Suppliers to establish customer contract Safeguards in place for customers requiring in emergency connection  Registrations can be superceded prior to energisation  NIE will implement equivalent process up to fieldwork despatch similar to the current ESB process 22 Private and Confidential
