After your initial enquiry, if you want to progress with your project, you will need to complete and submit a Connection Application and provide the relevant critical project criteria evidence for us to assess the criticality of your project.
During this stage we use your completed application and preferred connection option to perform network studies to identify network capacity and any network constraints. Based on this we will confirm the scope of work required to support the connection of your facility to the network.
We allow customers to complete detailed design, procurement and construction for greenfield assets, by engaging agreed vendors directly.
Please refer to Customer Design & Construct (D&C) for more information on the requirements and suitability for your project.
