General Issues Message Header – Additional Supplier ID removed

No longer send message on behalf of another Supplier Supplier ID values remain different in NI; RoI

Harmonisation would create major data migration challenge MPRN Address Processing

NIE will adopt county codes with English/Gaelic equivalents for RoI counties and separate codes for Derry/Londonderry

Postcode will remain in NIE address validation Other Common Data Segments

Consistent formats adopted Rejection Reason Codes

Where the same rejection reason occurs in both markets, then the same rejection reason code, based on RoI usage, will be used

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



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 options1. Harmonising on the RoI approach 2. Keeping the current, separate arrangement3. Allowing the NI decision to be driven by lowest implementation cost Depending on NIE systems decisions, options 1 & 2 may incur costs



Registration issues #3 – Cooling Off Period Cooling off period is feature of NI market for domestic customers

Suppliers prefer a single customer contactTo 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 possibilityNext slide discusses



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 issuesInitial 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 keypadCustomer must call in to complete transferKeypad codes cannot be input retrospectively



Registration issues #4 – General Data Usage type

Not used in RoIProposed to remain in NI as Supplier can drive change of DUoS tariffWill become optional: if omitted assume no change

EAI CodeRegulatory requirements require different code sets: NACE - SIC

Medical Equipment and Customer Special Needs codesSchema harmonised (single entry) but codes remain differentAdditional codes should be added using message 013

Appointment IDField is not used in RoIRepresents a confirmed appointment in NI

(even if date subsequently changes)



Registration issues #5 – Meter Data and Changes Serial Number and Timeslot Proposals in NI

Serial number is required in NI to protect against wrong meter in communal blocks.

• In RoI meter category may be provided as an alternativeTimeslot is mandatory in NI as systems do not support register type

• In RoI register type or sequence number may be provided as an alternative

Change to Interval MeteringNIE allow a change to (or from if <70kVA) HH metering as part of a CoS

request. Change to QH metering is not proposed to be allowed in RoI.



New Connection Registration

New Connection EnergisationRegistration is required for energisation of an NI domestic customerRegistration is not required for energisation of an RoI domestic customerNIE 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 energisationNIE will implement equivalent process up to fieldwork despatch similar to the

current ESB process



Registration Response Issues Issues variously impacting messages 101, 101P, 102, 102P and 105 Load Profile, Load Factor, Transformer Loss Factor

Load Profile populated where available (may not be available for 101P and 102P in NI as dependent on meter installation)

Load Factor not applicable in NI if NHH SToD metering discontinuedTransformer Loss Factor not applicable in NI

Customer ContactWill be included on 101P and 102P in both NI and RoI

Effective From Date on message 101P to be removed Read Cycle Code

Code cross refers to a date calendar in both NI and RoIConstructed using a day number in RoI … e.g. cycle day 40Constructed using a week & day number in NI…e.g. week 08 day 5

Rejection reason codes to be aligned to ensure the same code means the same thing
