Permanently unmetered supplies (PUMS) are connections without a meter that are provided for public facilities.
A small electrical installation for a public facility in a public place may be connected to the Ausgrid network without an electricity meter if its energy consumption can be reliably predicted. Such an installation is known as a ‘permanently unmetered supply’ (PUMS) and is suitable for traffic lights, small telecommunication installations, monitoring and surveillance equipment for public entities, and lighting for public facilities where standard public lighting criteria is not met.
Ausgrid requires that a PUMS:
It must also comply with Section 5 of the Service and Installation Rules of NSW.
Ideally, a PUMS load should consume energy constantly (be a non-variable load). If the energy the PUMS consumes is variable, then the connection may be required to be metered or, if unmetered, assessed at its maximum variable energy consumption rate. For example, for a PUMS that has an average current draw of 7 Amps but peaks at 10 Amps, we consider its energy consumption to be 10 Amps.
You need to get our approval for your proposed installation before you apply for a PUMS connection. We may charge a fee for this service and we may not approve your proposal. We’ll advise you of our fee before providing some services.
Let us know about your proposed installation, please:
If you want to mount your proposed installation on Ausgrid infrastructure, you’ll also need our approval to do this and a Facilities Access Agreement with us. For more information, see our network standard NS183 Installation of Private Attachments on Ausgrid Poles.
Please email the above information to firstname.lastname@example.org.
If we approve the proposed PUMS installation, we’ll send you a PUMS approved customer number and an approved load identification (Load ID) number.
Once you have a PUMS approved customer number and a load identifier you can apply.
To apply visit 'Apply for a Connection' and select Permanent Unmetered Suply.
