Researching your connection

Before you submit an application to connect to the electricity transmission system, please consider your connection requirements, such as:
 

  • Connection type 

  • Location

  • Connection size 

  • Planning consents

  • Connection date 

  • Cost of the connection


Our ConnectNow Research Assistant tool was created to help with your connection research. It shows you potential locations that could meet your needs and an estimated cost of the connection.

As of April 2023, all new connection applications should be submitted via the Electricity System Operator portal here. This replaces the previous connection application form process. Please refer to the page linked above for more information.

Customer checklist

  • Do you know the technical scope of your connection e.g. your connection size?

  • Do you know if your project has planning consents requirements?

  • Do you understand the costs of your connection?

  • Have you looked at the ESO Connection Registers to understand existing network connections?
