Multi-Unit and Large developments

This category includes new or altered connections for residential, industrial and commercial developments that involve any of the following;

  • more than 100 amps of load
  • connection at 11,000 volts or above
  • more than 6 separate units
  • machinery rated at 30 amps or more

You may be able to connect to the network without the network needing to be extended or its capacity increased (augmented). If so, you will require basic connection services from Ausgrid and the contestable services of an ASP2 to provide metering and make the physical connection between your electrical installation and the network. However, if you connect to a part of the network that another customer has funded during the last seven years, you will be required to contribute to a reimbursement scheme established and maintained by Ausgrid. If so, Ausgrid will notify you when it makes you a connection offer (or beforehand, if you make a preliminary enquiry).

If the electricity network needs to be extended or its capacity increased (augmented) to safely supply a property of this type, you may be required to fund works to augment the existing infrastructure, which means you are responsible for arranging and paying for Accredited Service Providers (ASPs) to perform the work to our standards. You will need:

  • an ASP3 to design the additional infrastructure
  • an ASP1 to build the infrastructure
  • an ASP2 to provide metering and possibly to make the physical connection.

The services provided by ASPs are known as contestable services.

Ausgrid provides standard connection services in relation to a connection that involves an ASP1 constructing assets designed by an ASP3.

Please note, additional requirements apply if you have or are proposing to install embedded generation, like solar panels, at the premises.

It may be helpful to make a site specific preliminary enquiry if you are considering the feasibility of a site or you need further information about connecting it or you wish to know which of our standard connection services will apply.

Next steps

Applications that need a certified design

If the network needs to be extended or its capacity increased (augmented) to meet the electricity needs of your large development then before work on constructing the necessary connection assets starts, you must retain an ASP3 to design them.  When we receive your connection application it will be incomplete without a certified design number so Ausgrid will start the design process by offering a design contract.

1. We will offer you a Design Contract . The offer includes a statement of fees as well as terms and conditions of contract.

2. You accept the Design Contract and pay the fees to Ausgrid.

3. We will send you Design Information so you can arrange an ASP3 to design the augmentation works and submit the design to us for certification.

4. We will do a desktop audit of the design to check whether it meets our standards.

5. Once we certify the design, your connection application can be completed. We will send you a connection offer, but there is an option to expedite a connection on the application form and if you have asked for expedition and indicated that the model standing offer of connection services for ASP1 connections is appropriate, the contract will commence on the date we certify the design.

6. If you choose not to expedite the connection, you have 45 business days to accept the connection offer.

7. Once the connection contract is in place, you arrange an ASP1 of your choice to build the network assets, and an ASP2 to provide metering services.

Ausgrid will inspect the work throughout the construction period to make sure it meets our standards before the power is turned on. Once electrified, the connection assets constructed by the ASP1 will be owned and maintained by Ausgrid as part of our network.

Please note, when the connection contract commences, another contract called Ausgrid’s Deemed Standard Connection Contract is formed between Ausgrid and the retail customer who will use the electricity at the premises. This contract takes effect as soon as the property is connected and electricity is being used.
