MCR 0173 – Sending of 331MM when import and export are sent to different suppliers

Detail of Change Request

Background

This MCR concerns non participant generator sites where import and export are registered to different suppliers. A 331 message issues to suppliers who are registered for import at a QH MPRN. This 331 message contains the meter details of the meter that is sent on the 341. Currently, when a supplier registers to buy the export from a specific non-participant generator, they do not receive a 331. The receipt of a 331 message would aid specific suppliers in the creation of meter/MPRN data on their systems.
