Non-SIT Supplier & Agent Test Data

Non-SIT Supplier and Agent Qualification Test Data Approach and Plan Consultation

The Code Bodies have made several updates to the Non-SIT Supplier and Agent Qualification Test Data Approach and Plan, and the updated document has been issued for industry consultation.

This document sets out the Test Data approach and provides a detailed view of specific data requirements for Non-SIT Supplier and Agent Qualification Testing.

You can view clean and red-lined versions of the updated document below:

Non-SIT Supplier & Agent Qualification Test Data Approach and Plan v1.1 (Clean)

At a high-level, updates to the document include providing more details around:

• Legacy and Gain Meter Point Administration Number (MPAN) Files required by Suppliers
• Default configuration and consumption data required by all roles
• The Test Data process

The deadline for participants to share their feedback and completed Comments Logs with the Code Bodies to MHHSQualification@elexon.co.uk is 17:00 on Wednesday 23 April 2025. You can view the Non-SIT Supplier & Agent Qualification Testing Data Approach and Plan Consultation Comments Log template to complete below:

Non-SIT Supplier & Agent Qualification Testing Data Approach and Plan Consultation Comments Log

Once the consultation closes on Wednesday 23 April 2025, the Code Bodies will review and respond to all participant feedback and provide an update at the Qualification Working Group (QWG) on Tuesday 13 May 2025. Following this, the updated document will be tabled for approval at the Qualification Advisory Group (QAG) on Thursday 22 May 2025.

Example Qualification Testing Framework (QTF) Files

The Code Bodies have also provided example QTF files to allow Non-SIT Suppliers and Agents to prepare for Qualification and data loading activities.

You can view these files in the library below. Whilst these files are not being issued for formal consultation (as Code Bodies cannot expect Suppliers to have loaded these within the consultation window), Code Bodies are keen to receive feedback on these files as soon as possible.

Please email any feedback to the Code Bodies to MHHSQualification@elexon.co.uk 

The contents of the QTF files are set out below, with further description and information around expected usage set out within the Test Data Approach and Plan.

• D0269_QTF_v350.dat contains QTF Market Domain Data (MDD), e.g. Market Participant Identifiers (MPIDs) of the legacy test stubs contained within the QTF, Line Loss Factors (LLFs) etc.  
• D0270_QTF_v350.dat contains QTF MDD, e.g. MPIDs of the legacy test stubs contained within the QTF, LLFs etc.  
• MPID-SUP-mpan-legacy-YYYYMMDD.csv is a sample file, containing Test Meter Point Administration Numbers (MPANs) the Supplier should load as legacy (existing) MPANs before migrating these MPANs to MHHS at the start of Qualification Testing.
• MPID-SUP-mpan-gain-YYYYMMDD.csv is a sample file, containing details of Test MPANs to be created / won during Qualification Testing (e.g. MPAN Attributes for an MPAN that is to be gained through a Change of Supply Qualification Test Cases (QTC), or a newly created MPAN in the case of a New Connection QTC).
• QTF Default Configuration Data.xlsx contains default data values required for QTCs where that data is not explicitly described in the QTF (e.g. the MPIDs of the MHHS Agents to be appointed during the migration process).
• QT-062 Consumption Data.xlsx is a sample file, containing consumption and / or meter readings to be submitted during settlement or consumption-related QTCs to enable the QTF to verify the expected results (e.g. the contents of IF-021s submitted by the Data Service). 
• LoadShape.xlsx contains lookup load shape consumption and total values. Ensure this file is open when using any QT-nnn Consumption Data.xlsx files to enable calculations to perform correctly.
