NMI

National Metering Identifier

The 10- or 11-digit ID for your electricity meter — needed when setting up a new electricity account.

The National Metering Identifier is a unique 10-digit (sometimes 11) number identifying your electricity meter on the national grid. When you move into a new home, your incoming electricity retailer needs your NMI to connect the meter to your account — usually printed on a previous electricity bill, or available from the property settlement agent or distributor. NMIs are used in NEM (National Electricity Market) states: QLD, NSW, ACT, VIC, SA, TAS.
