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 currently sent to Suppliers (but not TSO) 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.
