DR 0159 – Addition of 331MM to notify of QH meter removal during QH de-energisation with meter removal process

Currently when a QH meter is removed from a site undergoing de-energisation, no market message is
sent notifying the supplier of the removal. Message 106D is sent notifying of de-energisation but no
message is sent indicating the meter was removed.
The proposal is to mirror the process currently used for NQH de-energisation with meter removal for QH sites undergoing de-energisation with meter removal generating a 331 message. Since the current
design provides that all 331 messages are issued to TSO as well as the registered supplier, this change
will ensure that TSO are updated.
