The contestable connection process
Some new or upgraded electricity connections are more complex and need extra work on the electricity network.
These projects are usually designed and built by accredited electrical service providers, with Ausgrid overseeing safety and quality.
When does this process apply?
You’ll follow this process if your project:
- Needs upgrades to the electricity network
- Involves moving or extending existing power infrastructure
- Is larger or more complex than a standard connection
If you’re not sure whether this applies to you, start with Get connected or Need help to plan.
The process
We review your application
Once you submit your connection application:
- We check whether network upgrades are needed
- We may ask for more information
- For larger projects, you’ll be given access to our online Connections Portal so you can follow progress
We aim to review complete applications within 10 business days
We confirm what needs to be designed
If network upgrades are needed, we’ll:
- Explain what design work is required
- Provide an agreement covering that design work and its cost
- Share next steps through the Connections Portal
If anything is unclear, we encourage you to talk with us before accepting.
Choose your designer
You’ll nominate an accredited designer to prepare plans for the required network upgrades.
We’ll provide them with the information they need to:
- Design a safe and reliable connection
- Meet network and legal requirements
- Keep costs as low as possible
All designs are shared through the Connections Portal so you can track progress.
Design and review
Your designer prepares the plans and submits them for review.
We check the designs to make sure they:
- Are safe
- Meet network requirements
- Are ready for construction
If changes are needed, the designer updates the plans and resubmits them. This continues until everything is approved.
We confirm your connection terms
Once the design is approved:
- We confirm the connection arrangement and costs
- You’ll receive a connection agreement through the Connections Portal
At this point, construction can be scheduled.
Build and connect
After agreements are in place:
- An accredited constructor builds the approved works
- We may inspect the work during construction
- Safety checks are completed
Once everything is finished and approved, your connection is switched on.
Who’s involved?
For these projects, there are usually a few key players:
- You (or your representative) – tracking progress and approvals
- Accredited service providers – designing and building the works
- Ausgrid – reviewing designs, ensuring safety, and connecting to the network
We coordinate closely so the process runs smoothly.
Keeping things on track
To avoid delays:
- Engage experienced accredited providers early
- Respond promptly to requests for information
- Use the Connections Portal to monitor progress
If your project changes, let us know as soon as possible.
