Major customer connections
If you want to establish a major electricity connection, our dedicated Customer Team can guide and assist you through the connection process.
Major customer connections are typically high rise buildings and commercial or industrial sites, like shopping centres, exhibition centres, warehouses and mine sites.
Definition of a major customer connection
In our latest Pricing Proposal, a Major Customer Connection is defined as one that is for a Connection Asset Customer (CAC), Individually Calculated Customer (ICC) or an Embedded Generator (EG). These are usually sites where the load exceeds 1,000 kVA or 1 MVA or where power usage is typically above 4 GWh per annum at a single site or generation that is above 30 kV.
To connect an embedded generator (eg solar PV) above 30 kVA to our distribution network, please visit our large generation and batteries webpage.
The major customer connection process
The Major Customer Connection process aligns with Chapter 5A of the National Electricity Rules (NER).
There are five main stages in the process.
1. Enquiry and technical assessment
Submit a formal connection enquiry to us. You or your consultant can submit an enquiry through the Customer Self Service.
We'll do the necessary network investigations and provide an estimate of costs and timeframes after receiving all the required information from you. This estimate should help you to decide if you'll proceed and submit a connection application.
IMPORTANT: When completing the enquiry online, go to the ‘MyConnect’ section, select ‘Enquiry’, and then ‘Large Customer Connection’.
2. Application and offer to connect
If you wish to proceed, your consultant can submit the application on your behalf or you can submit it via Customer Self Service.
We'll complete further scoping and estimating to provide a connection offer for your acceptance.
3. Offer acceptance
You consider our connection offer and complete and return the necessary agreements to accept the offer.
4. Connection contract
Your negotiated connection contract will be established on the terms and conditions in your accepted offer.
This contract sets out the works that both parties will need to do for the connection and also governs the ongoing connection of your facility to our electricity network after the completion of the works.
5. Detailed design, construction and commissioning
Detailed design is finalised and the connection is constructed and energised.
Dedicated project sponsor
After we receive your enquiry, we'll allocate a Project Sponsor who'll be your single point of contact right through the connection process. They'll maintain regular contact with you and do their best to ensure your needs are met.
