Contestable services

Any work to design, construct or install assets that connect a customer’s installation to our electricity network is classed as contestable work.

When you want to connect your home, business or other premises, change or extend the electricity distribution network, you need a suitably qualified person to do the work. The NSW Accredited Service Provider (ASPs) scheme registers qualified service providers. The services they provide are called ‘contestable services’.

The following works on the electricity network are considered contestable services and must only be performed by a suitably qualified and authorised ASP:

  • designing network assets
  • extending or increasing the capacity of the network
  • connecting or disconnecting installations
  • installing and energising service lines

About Accredited Service Providers

There are three types of contestable services for which ASPs require separate accreditation:

  • Level 1 (ASP/1) - construction and installation of overhead and underground infrastructure
  • Level 2 (ASP/2) - installation or alteration of service cables
  • Level 3 (ASP/3) - design of new assets and modification of existing assets

Contact details for ASPs can be found at Energy NSW.

ASPs must be accredited before they can offer their services to customers. In addition, each staff member of an accredited service provider must be authorised by Ausgrid if his or her work is designing, or working on or in close proximity, to our network. Currently ASP/1s and ASP/2s are graded, based on their performance record and when Ausgrid inspects the work of ASPs, we charge different rates, according to the ASPs grade.

Even if the network needs no or only minimal augmentation before your connection can be established, you will need the services of an ASP/2 to install or alter the service wires that lead from the network to your premises.

If the network has to be augmented before your connection can be established and you are required to fund the work, you will first retain an ASP/3 to produce a design of the necessary augmentation assets. When Ausgrid has certified the design and a connection contract is in place, you will retain an ASP/1 to construct the augmentation assets.

The NSW Electricity Supply Act, 1995 states that customers who are required to make a capital contribution to the cost of augmenting electricity networks may choose the accredited service provider/s who will do the work.
