There are two types of residential subdivisions, Urban Residential and Rural Residential:
- Urban Residential subdivisions generally have an average lot size smaller than 2,000 m2
- Rural Residential subdivisions generally have an average lot size greater than 2,000 m2 each.
Our Subdivision Standards – Developer Design and Construct Estates* document provides further information about the connection process, including conditions and processes to follow.
Network connection process
1. Engage a consultant
You'll first need to engage a consultant from our Energex Accredited Subdivision Consultant* list. They'll liaise with us to progress your connection enquiry. This includes an assessment of our network to determine if any upgrade works are required to meet your energy needs.
As you’ll need to submit a design with your application, design parameters are included in our Subdivision Standards* document. These parameters outline what’s needed to ensure your design meets our connection and planning requirements.
* The above and other forms and documents that may be needed during the connection process can be found on our Technical documents webpage (use the search feature to look for the document name).
Information about multiple stage developments
If you have multiple (two or more) stages, a Master Plan showing the lots, conduits and high voltage network for the entire development is recommended.
Your design drawings must be completed by an Energex accredited designer. Your subdivision consultant will arrange this.
Your consultant will apply for connection of the subdivision on your behalf.
There'll be various costs, including an application fee, site inspection charges, commissioning charges and a bond. See our latest price lists on our Connections charges webpage.
We’ll need the following to process your application:
- Your engagement of an Energex accredited subdivision consultant
- Your acceptance of the application fee
- An electronic copy of the proposed subdivision Electrical Reticulation/Street Lighting plan
- A copy of the local government’s conditions for the development approval.
We'll generally make a connection offer to your consultant within two weeks of receiving your completed application.
To accept our connection offer and enter into a Subdivision Electricity Supply Agreement you must:
- Return signed copies of the Subdivision Electricity Supply Agreement
- Pay any relevant fees
- Satisfy all other requirements set out in the contract by the due date.
Read more about connection offer terms
If the connection offer is not accepted by the due date (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 fees for resubmission or application.
Site construction works may only commence once an Energex Accredited Service Provider has been appointed by your consultant and advised to us, and we have issued an Approval to Construct. Search for the approved list of Providers on our Technical documents webpage.
After construction, your service provider will notify us to energise the development. The timeframes for energisation are 20 working days for high voltage and 10 working days for low voltage.
7. Audit & acceptance
Following energisation, your service provider will submit a Certificate of Completion package to us. We'll then conduct a final audit.
Any defects found during this final audit must be rectified before a Certificate of Acceptance can be issued by us. Once this has been issued and all easements are registered, we can release any bonds we may be holding.
