Content of the Market Release

Item Area Title

MCR1111 Schema Release Debt Flagging

MCR1122 Schema Release Introduction of essential plant into the Retail Market design

MCR1136

Non Schema Release 131 MM to be added to Messages Tab on Extranet

MCR1151

Non Schema Release Add the Meter Multiplier and Meter Category code value for each relevant MPRN to the COM_REG and DOM_REG files available on the Secure File Transfer System (SFTS)

There is a TIBCO Upgrade Project which is responsible for delivery of components of MCR1111 and MCR1122 , in particular • The schema changes for 17MMs from MCR1122 • New schema 11.00.00• Webforms changes to 011/012 • Webforms is being replaced by this project• Emma replacements• TIBCO Upgrade

3 esbnetworks.ie

Another MCR – MCR1133

There is a further MCR viz MCR1133 which is also part of the Schema release , even though there are no IT changes

It has a tentative link to MCR1111 in that the SFTS that is currently being used for the Metered & SPU Debt Flagging will stop being used for that and start instead to be used for Grouped Unmetered Debt Flagging.

Overlaps

• There is a lot of functionality in this release, its being done in tandem with a rewrite of the Tibco Hub, the EMMAs and the Webforms replacement.

• It is the first schema release since Harmonisation, the COS processes are being changed significantly with Debt Flagging MCR1111, and 17MMs are being changed for Essential Plant MCR1122

• There is a fair bit of overlap between the items , with

· the Extranet in both MCR1122 and MCR1136 · the Downloadables in both MCR1122 and MCR1151 (they are different downloadable files) · COS MMs in both MCR1111 and MCR1122 · Service Order related elements in both MCR1111 and MCR1122

These are extracts from the minutes from the IGG on the 13th May 2015.

T O’Neill gave a presentation on 2 Reads sent in One message and Market Release 2015 which covered both the Schema and Non-Schema releases which are being delivered by ESBN in the same timeline as the Tibco Upgrade Project viz MCR1111,MCR1122, MCR1136 and MCR1151.

• The specific version of each MCR that is being implemented was highlighted as well as

clarifications which had been provided for MCR1111 and MCR1122 , the details of which are available on the calendar for the 10th April 2013.

• Changes to the Downloadable files arising from MCR1122 and MCR1151 will be visible from the next scheduled downloadable run after the go live viz in December 2015.

• Extranet changes arising from MCR1122 and MCR1136 will be available from the go-live as will Debt Flagging and Essential Plant Market Messaging functionality.

• The location on three tabs of the Extranet of where the Essential Plant Flag can appear was presented, noting that the existence of Essential Plant will be shown by ‘YES’ on the Extranet, and not with a value of 1 which is stated in MCR1122 – Refer to slides for full details.

What are we testing (1)

What to expect

1. That the changes work exactly as written in the MCR (please ensure you have the right version of the MCR or Defect)

- Except where a later clarification to the MCR has issued• See IGG 10th April 2015 for MCR1111 and MCR1122 Clarifications• See IGG 13th May 2015 (EP on Extranet & included in this slide deck)

2. That nothing unrelated to the changes is impacted, it all works as usual

8 esbnetworks.ie

MCR1111 – Debt Flagging

MCR1111

This is wholly concerned with extensive changes for the new automated Debt Flagging functionality for NQH, QH and SPU

9 esbnetworks.ie

MCR1122 – Essential Plant – Changes to 17 MMs

MCR1122 – as well as the Data side of this change, there are a lot of Market Messages impacted - overall there are 17

A new Optional Boolean Flag ‘EssentialPlantFlag’ is being added to each of the 17 MMs.All of these 17MMs are outbound from ESBN, so this means that there are no Webforms changes for the EP.

Is this file being Changed? MCR1122 No No No YES YES

MCR1151

(high level extract – see text for full details)

Currently the COM_REG and DOM_REG files made available on the SFTS do not contain the Meter Multiplier or the Meter Category consistently across both of these files.

The objective of this MCR is that a supplier should be able to obtain the Meter Category and Meter Multiplier within both the COM_REG and DOM_REG files.

MCR1122

(high level extract – TON can get further info as required)

The content of the flag will be made available to Suppliers on the Extranet and the Downloadable Meter Point Details file.

On the Downloadable Meter Point Details files this field will be made available in the Commercial and Unmetered extracts and directly after the MICfield.

Where this flag appears with a value of 1 on the Extranet or the Downloadable Meter Point Details file it will mean that there is essential plant at thisMPRN.

It is not proposed to populate a value of 0 on the Extranet for MPRNs

• the "All" check box • or the "Meter Works" check box is selected

(extract)

The content of the flag will be made available to Suppliers on the Extranet and the Downloadable Meter Point Details file.

Where this flag appears with a value of 1 on the Extranet or the Downloadable Meter Point Details file it will mean that there is essential plant at thisMPRN.

It is not proposed to populate a value of 0 on the Extranet for MPRNs Comment: the exact location of the new field on the Extranet will be communicated throughout the implementation phase.

Final points that may be of use

• It can be confirmed that schema version 11.00.00 will be the same format and structure as schema version 10.00.00.

• A new attribute EssentialPlantFlag has been defined in the DataDefinition.xsd

• It is linked to an existing type – Flag_Type, it inherits the Flag_Type attributes, e.g. Boolean.

• Now that it is defined it can be added into the relevant messages.

• Schema validation is now centralised on the Hub, but Suppliers will still need the Schema to update their own backend systems to correctly make the relevant messages with the new fields included.

• It is currently ESBN’s intention to release the Schema on 21st August.
