DR 0121 – Extra validation for correct meter point status required at creation of some messages

Suppliers currently receive the following messages to notify them of De-energisation and Reenergisations
in relation to NQH and QH sites:
• 306 NQH De-energisation Notification
• 307 NQH Energisation Notification
• 106D Meter Point Status Confirmation – De-Energisation
• 106E Meter Point Status Confirmation – Energisation
In addition, the following message notifies suppliers of the technical details of meters installed
including the meter point status at an NQH site
• 332 NQH Technical Meter Details
This means that the following rules should apply in all cases:
• The Market Design v5.1 states that the only meter point status applicable to the 106D and
306 messages is D – De-energised
• The Market Design v5.1 states that the only meter point status applicable to the 106E and
307 messages is E – Energised
• The Market Design v5.1 states that the meter point status can be either ‘D’ or ‘E’ as
appropriate
Two non-compliant examples have come to light: a 306 message was received by a Supplier
with a meter point status of E – Energised and a 307 message was received by a supplier with
a meter point status of D – De-energised.
