Detail of Request Reason for Request

The RoI Retail Market currently uses ARIS, a Business Process Modelling tool, to display the Market Design (Market Process Diagrams, Market Messages, Market Segments and Codes and other documents relevant to the Market Design). In 2013 further to discussions with Market Participants and approval from CER, a decision was made to exit from ARIS. This aligns with the format in use by NIE and Gaslink. Due to the volume of MPDs and Market Messages to be converted multiple DR/MCRs are required:-

At the IGG on 26th

March 2014 DR 1145 was approved. The MCR was subsequently approved at the IGG on 28

th May 2015 which covered 21 of the 41 MPDs and these are available on the RMDS website.

At the IGG on 14

th January 2015 DR&MCR 1155 were approved. The MCR covered 9 of the 41 MPDs and

these are available on the RMDS website. This DR&MCR is intended to cover the final 11MPDs to be converted as well as documenting where all the documentation held in ARIS is now located on the RMDS website. This brings to a close the full transfer of all information held in ARIS to document format.

Proposed Solution

This solution will be delivered by generating MPD documents and Market Messages using Visio diagrams incorporated into MSWord documents They will be generated into PDF format and published to the RMDS website for access by Market Participants. Market Messages will be drafted in Visio format as per their current structure in ARIS but generating the HTML from Visio and publishing to the web. These would facilitate the ability to drill down to Segments and Data Codes. This project will be delivered in three stages (this being the final DR) and a new DR/MCR will be drafted for each stage. As these MPDs were being drafted and converted there were some corrections identified that are also recorded in the History of Changes for each converted MPD. As this is the final DR/MCR related to the ARIS conversion it is necessary to summarise the overall changes in a project close-out document for future reference. This close-out document is embedded in this DR/MCR here and can also be found on the RMDS Website under the ARIS tab in the Retail Market Design main tab. The above document ensures that all items contained within ARIS were converted where necessary and located on the Retail Market Design section of the RMDS website. The ARIS conversion project required:-

ages for the Briefing Documents, Working Practices, Un-metered template. Market Message MPD Matrix,

The final 11 MPDs to be converted are listed below:-

3. Supplementary Information

Registration Validation Rules for a CoS (NQH Settled)

Failure of the following validations will cause the Registration to be rejected:-

The Supplier must have provided all mandatory information.

The MPRN must have been assigned and not terminated.

The Supplier ID is a valid one and the Supplier has a DUoS agreement.

The Supplier must be entitled to register a Meter Point under the legislation and in accordance with the Trading and Settlement Code.

The Supplier must warrant that a supply agreement exists with the Customer at the Meter Point being registered. The Supplier must provide a Supplier Unit that is valid for the Supplier.

The Supplier Unit must not be a Trading Site Supplier Unit.

The Supplier must provide a sub-aggregation code (SSAC) that is valid for the Supplier Unit and for the class of metering.

A separate CoS may not be in progress for this meter point.

A CoS was completed with an effective date less than twenty days before the required date for the requested Change of Supply. This rule does not apply if the CoS includes a change of tenancy or legal entity.

Any Meter Configuration change request must be from the list of permitted Meter Configuration code changes. In cases where the change requires a wiring certificate, connection agreement or quotation then the Meter Configuration change is not permitted. If a Meter Configuration change is not permitted then the CoS must be completed before the Meter Configuration change can be considered. The

New Supplier will be required to submit a separate meter works request.

The read arrangements for the CoS are valid.

A Customer read is not allowable for a Maximum Demand site. Required date must be no more than forty days after the Registration receipt (required date is not required for a scheduled read).

Required date is mandatory if a Customer read is to be used and may not be more than three days prior to receipt date. Required date must provide at least five days notice for a Special Read or meter works site visit.

Meter point is listed as eligible to change Supplier only if QH metering is installed and QH metering and communications have not yet been installed. In this instance DSO will be requested to prioritise QH meter and communications installation and, following this, the Supplier will be asked to re-submit the Registration as a QH Metered Registration.

EAI must be valid & not blank for sites over 30Kva.

Failure of the following validations will cause the Registration to be rejected unless the DSO agrees that the exception is allowable:-

Meter Point Address advised by Supplier is materially inconsistent with Meter Point Address known to MRSO. DSO may accept or reject the New address submitted by the Supplier.

Failure of the following validations will cause the Registration to be Provisionally accepted, unless rejected above, pending approval by the DSO:-

The Meter Point is de-energised. In this case the CoS will be effected using the re-energisation reading.


Page 20 of 23

The Connection Voltage is equal to or exceeds MV (Medium Voltage) and there is no Connection Agreement in place or there is a change of Customer name or registered company number. In this case the DSO must confirm the existence of a signed Connection Agreement before the Registration is accepted.

A token meter is installed. In this case the DSO is requested to remove the token meter and the CoS is effected using the readings taken at removal.

Requests for the use of a scheduled, Customer or Special Read will be cancelled.

Treatment of Requests for Estimates

An estimate is not allowable for Maximum Demand sites or where there has been no actual read in the previous twelve months. In these circumstances

MRSO will disregard a request for an estimate but shall not reject the Registration.

CoS Read Selection

MRSO will endeavour to select a CoS reading in accordance with the instructions of the New Supplier.

However, the following situations can occur:-

Where a Customer Read is requested then:-

If a meter works, re-energisation or Special Read becomes available in the five days following the required date then this will be selected and used in preference to a Customer reading.

If a Customer reading is requested but not provided & validated with the Registration Request then if no valid reading becomes available in the five days following the required date the MRSO will estimate a reading, dated at the required date, if an estimate is allowable and the New Supplier has indicated an estimate is acceptable.

A Customer reading provided by a Supplier may not be dated more than three days prior to the DSO receipt date.

An estimate shall not be used in preference to a Customer reading.

Where a Special Read is requested but does not become available within five days of the required date, then:-

If a meter works, re-energisation or scheduled read is available in the five days following the required date then this will be selected and used.

If no valid reading becomes available in the five days following the required date the MRSO will estimate a reading, dated at the required date, if an estimate is allowable and the New Supplier has indicated an estimate is acceptable.


Page 21 of 23

Where a Scheduled Read is requested the following should be noted:-

If a scheduled read which is usable for a CoS is collected during the five day objection period, MRSO will not issue a 300 MM for this reading and then withdraw it when the CoS is completed subsequently.

Similarly where an estimate is used the 305 MM is not sent and subsequently withdrawn. These CoS readings are sent only on the 310 MM / 320 MM.

If the New Supplier indicates 'No' to an estimate, and the read is an estimate, a 305 MM will issue to the Old Supplier and then be withdrawn if the New Supplier subsequently agrees to use the estimate for the CoS. (The estimate could result from a planned estimated read, or an implausible Scheduled Read or Customer Read which is subsequently adjusted to an estimate.)

If the site is Provisionally accepted, and a read is received while awaiting for conditions to be met, the 300 MM / 305 MM will issue to the existing Supplier (Old Supplier) and when the conditions are met and complete the COS back to the read - we will withdraw the 300 MM / 305 MM and issue 310 MM to the old Supplier.

The issue of 300 MM / 305 MM is suppressed by means of a billing block. The billing block can be removed manually by a user. Where a user

does remove the billing block while the CoS is still in progress, a 300 MM / 305 MM will issue and then subsequently be withdrawn if used for

the CoS.

Where a Scheduled Read is requested then while the meter reading order is open:-

If a meter works, re-energisation or Special Read becomes available then this will be used for the CoS.

If a Customer read becomes available and is allowable then the Customer read will be used for the CoS.

Where a Scheduled Read is requested, but the meter reading order is closed and no reading has been obtained then:-

If a Customer read becomes available and is allowable then the Customer read will be used for the CoS.

If an estimate is not allowable because the site is a Maximum Demand site MRSO will request a non-chargeable Special Read.

If an estimate is allowable MRSO will estimate a reading, dated at the scheduled read date, for use as the CoS reading.

Where no reading becomes available or can be estimated under the above rules then MRSO will inform the New Supplier of the situation.

If an estimate is not allowable because there has been no read in the previous twelve months, then the Supplier may either:- o Provide a Customer read. o Provide an access arrangement to allow DSO to collect a non-chargeable Special Read.

In other circumstances the Supplier should contact MRSO to determine an alternative read arrangement.


Page 22 of 23

An estimate is not allowable for Maximum Demand sites or where there has been no actual read in the previous twelve months.

Change of Read Arrangements

If a Supplier opts to alter the read arrangements for a CoS read then, provided a valid read has not already been obtained and the New

arrangements are valid the MRSO will instruct DSO accordingly.

Processing of outstanding Meter Works requests

When a CoS request is received by MRSO a check will be made for any open service orders. Where such orders exist, MRSO will manually

notify both the old and New Supplier of any outstanding Meter Works or de-energisation request. As a result of this notification then:-

The Old Supplier may cancel the work order subject to the applicable DSO/MO rules. In this case the New Supplier will be informed of the cancellation of the work order.

The New Supplier may cancel the Registration Request.

In the event that neither Supplier cancels their request, both the meter work and CoS proceed as normal then the Old Supplier will remain

liable for any charges arising from the work they have requested.

Treatment of Medical Equipment Special Needs

Special arrangements are in place for the management of Medical Equipment Special Needs (MESN) flags during COS operations which are

not also COLE. These arrangements include the restoration of previous MESN flags in cases where completed COS operations are

subsequently cancelled and MESN details could otherwise have been lost. These arrangements relate only to the two Medical Equipment

Special Needs (MESN) flags of Life Support (0003) and Non-Life Support (0004) and do not affect Customer Service Special Needs (CSSN)

flags.

Specifically:-

1. Where there is an MESN associated with an existing Customer and the 010 MM submitted includes an MESN, the existing MESN will be deleted and replaced with the submitted MESN value and VCAttributeDeleted=”false” will appear on the 102 MM.

2. Where there is an MESN associated with an existing Customer and the 010 MM submitted does not include an MESN, the existing MESN will be deleted and VCAttributeDelete=”true” will appear on the 102 MM.


Page 23 of 23

3. The presence or absence of CSSN flags, either associated with an existing Customer or submitted on the 010 MM, will not impact in any way on the processing of MESNs above. For example, if an MESN is associated with an existing Customer and only CSSN flags are submitted on the 010, then a warning message will issue as in point 2 above.

In summary,

The deletion of an MESN will always be flagged where no Replacement MESN has been submitted on the 010 MM.

The deletion of CSSNs is done without warning.

The deletion of MESN flags is effective only when the CoS completes. If the CoS is subsequently cancelled after completion, the previous

MESN value, if any, is restored.

4.0 Supplementary Information

Registration Validation Rules for a Change of Supplier (QH Metered)

Failure of the following validations will cause the Registration to be rejected.

The Supplier must have provided all mandatory information.

The MPRN must have been assigned and not terminated.

The Supplier Id is a valid one and the Supplier has a DUoS agreement.

The Supplier must be entitled to register a Meter Point under the legislation and in accordance with the Trading and Settlement Code.

The Supplier must warrant that a supply agreement exists with the customer at the Meter Point being registered.

The Supplier must provide a Supplier Unit that is valid for the Supplier.

The Supplier must provide a sub-aggregation code (SSAC) that is valid for the Supplier Unit and for the class of metering.

Where the CoS contains a Trading Site the Registration Request must be consistent with the Wholesale Market Registration details.

The required date must be no less than five and no more than forty days after the Registration receipt date.

The Supplier may not provide a read arrangement.

A separate Change of Supplier may not be in progress for this meter point.

A Change of Supplier was completed with an effective date less than 20 days before the required date for the requested Change of Supply. This rule does not apply if the Change of Supplier includes a change of tenancy or legal entity.

Meter point is listed as eligible to change Supplier only if QH metering is installed and QH metering and communications have not yet been installed. In this instance DSO will be requested to prioritise QH meter and communications installation and, following this, the Supplier will be asked to re-submit the Registration as a QH Metered Registration.

EAI must be valid and not blank for sites over 30kVA.

Failure of the following validations will cause the Registration to be rejected unless the new information is approved by the Distribution

System Operator:-

Meter Point Address advised by Supplier is materially inconsistent with Meter Point Address known to MRSO. DSO may accept or reject the new address submitted by the Supplier.


Page 12 of 12

Failure of the following validations will cause the Registration to be Provisionally Accepted, unless rejected above, pending approval by the

DSO:-

The Meter Point is de-energised. In this case the Change of Supplier will be effected upon re-energisation.

The MIC is equal to or exceeds MV (Medium Voltage) and there is no Connection Agreement in place or there is a change of customer name or registered company number. In this case the DSO must confirm the existence of a signed Connection Agreement before the Registration is accepted.

CoS for Generators

The market process as detailed for Change of Supplier Quarter Hourly sites can also be applied to Participant and Non Participant

Generators.
