Connect your industrial plant

We want to work with you to ensure you have a connection to New Zealand's National Grid that fits your needs for the size, location and type of industry being connected.

Connecting new industry to the National Grid takes careful and coordinated planning.  Please engage with us early so that Transpower (as Grid Owner and System Operator), our service provider network and your own teams and service providers can meet your expectations delivering on an expanding programme of work.  The overall process is provided in the diagram below:

Impact of Tiwai exit

Transpower, as System Operator, has completed analysis to determine system operation and security impacts of Tiwai’s exit following the initial announcement of an August 2021 closure. While Tiwai has signalled ongoing operation until at least 31 December 2024 and the outlook for its ongoing operation is positive. As a prudent System Operator we have continued to assess operational implications associated with a possible closure.

This webpage shares the findings of our analysis to date.
