Permanently unmetered supply

Permanently unmetered supplies (PUMS) are connections provided for public facilities where energy consumption can be calculated and a meter can’t be safely, reliably or economically installed. This includes traffic lights, small telecommunications installations, monitoring and surveillance equipment, and specific lighting arrangements for public facilities.

What you need to know before you apply for a PUMS connection

New installations and all device alterations (including disconnections) to existing installations require a connection application. PUMS customers must fund any network alterations associated with their connection and Ausgrid will make a negotiated offer where we agree a PUMS connection is appropriate. High volume PUMS customers can engage Ausgrid to develop a customer specific negotiated contract which can be accepted on application much like a basic or standard connection offer. 

Types of unmetered connections

There are two different types of unmetered network connections, market and non-market:

  • Market unmetered connections (or Type 7 metering installations) are recognised as installations settled in the National Electricity Market (NEM) and these connection customers are allowed to choose their energy retailer. You must apply through AEMO if you intend to be a market unmetered connection as well as applying to Ausgrid.
  • Non-market unmetered connections are recognised as installations settled directly between the electricity distributor (e.g. Ausgrid) and the local retailer (in Ausgrid's network e.g. Energy Australia).

Do you have a PUMS approved customer number and Load ID number?

  • you will need to obtain approval from Ausgrid before making a connection application if you do not already have a PUMS Approved Customer Number and an Approved Load Identification (Load ID) number for your proposed installation. To do this, please submit a preliminary enquiry describing your PUMS request.

Minimum requirements for a PUMS connection

Generally the following minimum load requirements are required to be met:

  • maximum of 10A single phase
  • supplied from one network point of common coupling
  • energy consumption that can be assessed without a meter.

All PUMS in our network area must comply with the requirements of the Service and Installation Rules of NSW (Section 5, Special Small Services).

If your proposed installation will be mounted on Ausgrid assets you will also need a Facilities Access Agreement with Ausgrid and technical approval for the installation mounting arrangements in accordance with the Network Standard NS183 - Installation of private attachments on Ausgrid poles.

Ausgrid typically require the following details:

  • Confirmation that the proposed installation is on public land and meets the minimum PUMS load requirements
  • Full technical specifications for the proposed equipment and operational arrangements (such as 24 hour, timer control or PE cell control) to enable the daily average load to be calculated
  • A single line diagram of the proposed installation.
