Commercial and industrial subdivisions

The electrical infrastructure in new commercial subdivisions is designed according to lot size, unless you specify a higher load.

Charges for electrical infrastructure vary, as they are based on the individual requirements of each request.

Read more on electricity supply requirements

As a minimum, we require provision for a 3 phase 30 kVA supply to each commercial and  industrial lot, unless otherwise notified and agreed. For relevant specifications, refer to the Developers Handbook (PDF 329.4 kb) and Manuals.

If you’d like to see areas on our electricity network that can support a new subdivision, refer to our interactive Network Capacity Map.

The Developers Handbook (PDF 329.4 kb) provides further information about the complete connection process, including the connection offer stage and supporting explanations.

Network connection process

1. Enquiry

You will first need to complete the online developer enquiry form before submitting a subdivision connection application. We will contact you within 5 business days (or other agreed date) to confirm details and provide more information on the process.

We’ll also provide you with a Works Request number.  This number should be referenced on all future communications with us.

As you’ll need to submit a design with your application, we’ll provide you with design parameters. These parameters outline what’s needed to ensure your design meets our connection and planning requirements. This can take up to 25 business days depending on a range of factors, including:

  • Quality of information provided on your enquiry form
  • Available network capacity.

If need be, we’ll contact you during this period to negotiate an extension to help us give you the information you need to complete your application.

Information about multiple stage developments

If you have multiple (two or more) stages, a Master Plan showing the lots and transformation locations for the entire development is required.

If a formal planning study is required, we will provide a quote and time frame for this work.

A design concept/master planning meeting can be requested by selecting the ‘Concept meeting’ check box when completing the developer enquiry form.

2. Design

Your design must be completed by a design consultant from our Approved Subdivision Designers list (PDF 196.8 kb).

3. Application

To apply for connection to our network, you must email a completed Network Connection of Subdivision/Public Lighting Application Form (PDF 549.3 kb) to ccg.contestable@ergon.com.au.

There will be various costs, including an application fee, design fee and inspection charges.

In order for us to process your application, the following is required:

  • Acceptance of the application fee, design fee and any other relevant charges
  • An electronic copy of the proposed subdivision Electrical Reticulation/Street Lighting plan and other plans detailing other services (i.e. sewerage, water, storm water, telecommunications and gas)
  • A copy of the local government’s conditions for the development approval
  • Details of the construction contractors you have engaged from our Approved Subdivision Construction Contractors list (PDF 197.0 kb)
  • Nomination of the materials suppliers for any Category A materials (refer to Developers Handbook (PDF 329.4 kb)).

4. Offer

We will make a connection offer within 65 business days of receiving your completed application. It must be accepted within 20 business days.

You may accept our connection offer and enter into a new Negotiated Connection Establishment Contract by:

  • Returning the signed copies of the relevant documents
  • Paying any relevant fees
  • Satisfying all other requirements set out in the contract by the due date.

Read about connection offer terms

If the connection offer is not accepted within 20 business days (or other date agreed in writing with us), it will automatically lapse.

If you wish to recommence the project at a later date, a new connection application will be required along with the relevant connection application fee.

5. Construct

Site construction works may only commence following a pre-start meeting and confirmation that design plans have been reviewed and approved by us.

We need to inspect conduits or other such infrastructure before its buried or hidden from view. We may also do random audits at any time during the construction phase without notice.

We’ll conduct a final audit after construction is completed. Any defects found during this final audit must be rectified before a Certificate of Acceptance can be issued.

6. Connection

It’s important that you notify us of the expected completion date well in advance, so we can schedule the final testing and commissioning works. This helps to ensure the timely connection of the development.
