Commercial, industrial & developer connections

New connections, upgrades and alterations

For more information about connecting the power when you're:

  • Building a new commercial or industrial property
  • A property developer
  • Altering your commercial or industrial electricity connection

SA Power Networks has an obligation to provide Negotiated Connection Services for larger connections. Our processes are in accordance with Chapter 5A of the National Electricity Rules (NER) and comply with the National Energy Customer Framework (NECF). They are detailed via the links provided below;


Negotiated Connection Service

A Negotiated Connection Service is a connection service where the customer and SA Power Networks negotiate the terms and conditions (including price) for the provision of that service. Typically such services will require SA Power Networks' electricity network to be altered, extended or upgraded in order to enable the connection or to accommodate the extra load.

Negotiated Connection Services are provided to the following groups of customers:

  • Commercial customers (eg real estate developers, retailers)
  • Industrial customers (eg manufacturers)
  • Embedded generators (ie customers with a generating capacity greater than 10kVA for a single phase connection and greater than 30kVA for a three phase connection)
  • Residential customers where a network extension or upgrade ('augmentation') is required

Note: if you are a small business customer with an electricity capacity of less than 63 amps, please refer to the Residential connection

How do I apply

Commercial, Industrial Customer & Developer

The following information explains the key steps involved in the connection/alteration process.

Step 1: Submit connection/alteration request

You (or your elected consultant) must complete the online application Form B to provide all the required information for us to assess your proposed connection.

Step 2: SA Power Networks assess your request

Upon receiving your complete application we will conduct a preliminary assessment to determine and advise you of the type of service required and the constructability for the proposed connection/alteration. We may ask you for additional information or pay a visit to your premises to decide the best location for the required work. Depending on how complex the assessment work is, we will charge you an offer fee to cover our costs. This fee is not refundable but is rebatable should you accept our Connection Offer.

Please note that under the current law, we are entitled to charge you a site inspection fee, if required, to cover our cost.

Step 3: Offer and acceptance

Once we complete the assessment we will do our best to make a Connection Offer to you within 65 business days (or within a period agreed between you and us) of receiving your application. If you accept our offer, you need to sign the Connection Contract and return it to us.

Step 4: Specification, design and construction

SA Power Networks is available to undertake all the design and construction work required to establish the connection. Alternatively you can choose an external consultant/contractor to undertake part of the design and construction work. In this case we will provide the relevant specification to you or your consultant to complete that part of the work.  

Below is a list of accredited contractors:

Step 5: Connection to the network

Once the construction work is complete, you or your elected consultant/contractor will need to complete the application Form A and send it to your electricity retailer who will in turn submit it to us. We will then invite your electrician to book an appointment through our REX System and will complete the final connection according to the agreed time.

For more information on the connection process, see Customer fact sheet

Large Embedded Generators

A Large Embedded Generator is one defined as having a generating capacity greater than 10kVA for a single phase connection, and greater than 30kVA for a three phase connection. If you are proposing the installation of such a unit, please refer to our guides and technical standards for details on how to establish the connection for your generating unit.

Ongoing Supply

Once your connection is established, we will provide ongoing electricity supply to you according to the standard supply contract we have with you. This is a deemed standard contract we have with most of our large customers and has been approved by the Australian Energy Regulator. You do not need to sign the contract.

Note: Under special circumstances, we will negotiate a specific ongoing supply contract with a customer to meet their special needs. It will be carried out in accordance with the law.

Connection fees & tariffs

We may require you to pay towards the cost of the connection, extension and augmentation works. This payment is separate to the monthly charges you receive from your retailer for ongoing electricity supply. Depending on the scale and complexity of work required, these connection charges can vary significantly dependent on capacity requested by the customer and the location of the development relative to the Distribution Network. These charges and tariffs are determined by applying our pricing methodology obligations in accordance with Chapter 5A and Chapter 6 of the National Electricity Rules (NER) and detailed in our Connection Policy.
