For a new connection or a connection alteration to a large commercial or industrial site, you will need to follow the process below.

New connection or alteration to an existing connection


Receive connection advice

  1. Email us at to arrange an initial discussion.
  2. Submit a request for preliminary network advice (PNA).
    • Maximum demand calculations and site plans must accompany all PNA applications.
  3. We will undertake initial design works to confirm the connection can proceed.

Apply for connection services

  1. Apply for an electricity network connection or alteration once you’re ready for a detailed electrical design.
    • Maximum demand calculations, site plans, single line diagram, and consumer mains cable details must be provided at this stage.
    • A soil resistivity test report and site survey/geotechnical report is required where a substation is proposed within the block boundary.
  2. We will review your application and prepare a connection offer.
    • The connection offer will include the connection agreement, sketch plan of the works (including responsible parties), and the invoice.
  3. Once you accept the connection agreement through execution of the contract and pay the invoice, an Evoenergy Project Manager will establish regular project meetings, proceed with the procurement of equipment, and a construction schedule will be developed.
    • We may work with customers to develop a preliminary works agreement (PWA) to allow for advanced ordering of equipment/materials and design time.
  4. Once construction is complete, we will help you establish the right protocols and testing before establishing an energisation date.

We recommend reaching out to us about your project as soon as possible. The below timeframes are a guide and will vary depending on the scale of the project:

  • Planning and advice: 3-6 months
  • Preliminary design & assessment: 3-4 months
  • Detailed design & offer to connect: 8-10 months
  • Construction: 2-4 months
  • Commissioning & beyond: 1 month

The cost for these connections can be found in our Connection Policy. The cost will vary depending on the type of connection.

Please note a PNA does not include a quote, only an application for connection includes this


If you need to cancel your project, please contact the Evoenergy representative you have been liaising with for your connection.
