What is a NMI?

NMI stands for National Metering Identifier. It is a unique 10-digit number used to identify an electricity meter in the National Electricity Market (NEM).

For customers outside an Embedded Network, the NMI identifies their market meter and is used in market systems (MSATS) to facilitate electricity supply and retailer arrangements.

For customers within an Embedded Network who choose to purchase electricity directly from their retailer of choice, an on-market NMI is established for their connection, allowing their electricity supply to be managed through the National Electricity Market.
