What is the NMI?
The National Metering Identifier (NMI) is a unique 10 or 11 digit number used to identify every electricity network connection point in Australia.
Every connection to the national electricity network is given its own NMI. That includes all types of metered and unmetered electricity connections, like homes, businesses, farms, sheds, pumps, street lights and watchman’s lights.
You can use the NMI to find out information about your electricity connection.
Where do I find my NMI?
You can find your NMI on your electricity bill.
If you don’t have an electricity bill handy, you can call Ergon Energy Network on 13 74 66 (Mon to Fri, 7:00am – 6:30pm) or your current electricity retailer to ask for your NMI.
Why is the NMI important?
The NMI is used to record important data about your electricity network connection point. It is used for:
- Identifying your network connection point
- Collecting metering usage data
- Requesting any electricity connection works to be done at your premises
- Transferring from one electricity retailer to another.
How do I get a NMI for a new connection?
If you request a new electricity network connection, the NMI will be provided by your electricity distributor, such as Ergon Energy Network. It will appear on your next power bill.
Does my NMI ever change?
The NMI at your electricity network connection point will always stay the same unless:
- You change the location of your current electricity network connection point
- You remove your electricity connection, for example when demolishing a building
- Your electricity connection changes from low voltage to high voltage (usually large businesses).
