Digital meters, are the next generation of electricity meters, replacing analogue ones. They measure your home’s electricity use in 30-minute intervals, and can send this data automatically to your energy retailer every day using a secure wireless network.
Digital meters are installed by qualified electricians, and depending on your home’s set up and situation, the installation process normally takes 30 minutes to 2 hours to complete.
Your National Meter Identifier (NMI) is a unique number that you'll need if you change your electricity retailer. It’s always listed on the back of your electricity bill.
What is the NMI used for?
Every connection to the national electricity network is given its own NMI (National Meter Identifier). The NMI is used to ensure the correct meter data is connected to your account. The NMI is also used to:
identify your supply address
identify the meters and meter types at your connected address
ensure that you are billed for the right amount of usage at your property.
Where do I find my NMI? You can find your NMI (11 digits) under ‘Your electricity supply details’ on page 2 of your electricity bill. To obtain specific information about a NMI, please reach out to our web chat team here.
Does my NMI ever change? The NMI should always stay the same for your electricity network connection point unless the location of your electricity network connection point changes - e.g. When a building is demolished, and a new meter is installed.
Does my NMI stay the same when I move? The NMI is associated with an electricity network connection point, therefore when you move, you will have a new NMI at your new location.
It’s your Meter Identification Reference Number. If you live in VIC, QLD and SA, this unique number identifies your gas meter and can be found on the back of your gas bill.
Don't have a copy of your bill? Your MIRN should also be featured on your natural gas meter - see our guide on how to read your meter.
