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:-

reading date is the date that DSO collects the reading or, for a
Customer read provided by the Supplier, the date specified by the
Supplier) to determine the CoS date. The CoS will be effected at
00h00 on the CoS
date (The changeover date is, for a Customer, Special or
scheduled read, the day following the read and for a meter
exchange, the day of the meter exchange), meaning that consumption
on that date will be provided to and settled by the New
Supplier.
** The permitted period for a CoS is:- Where a scheduled read
was requested, twenty days after the date of the

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.
-
MPD 01 CoS NQH Market Design Version 10.5
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.
-
MPD 01 CoS NQH Market Design Version 10.5
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.
-
MPD 01 CoS NQH Market Design Version 10.5
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.
-
MPD 01 CoS NQH Market Design Version 10.5
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.
-
MPD 02 CoS QH Market Design Version 10.5
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.
