We need to continually operate, maintain and develop New Zealand's transmission network - the National Grid - to ensure we meet the ongoing electricity needs of New Zealanders.

We have identified that the Churton Park section of our Oteranga Bay-Haywards transmission line in Wellington will require its conductor (ie wire) replaced by 2021.  

A need to investigate

Before we replace the conductor on this line we need to make sure that from an economic perspective, it is the best option to undertake.  There may be other options including new generation, demand response, smaller or larger capacity conductor, that alone or in combination with each other could avoid or defer our need to replace this conductor.

Why we're doing it

This line is part of the HVDC inter-island link that transports bulk electricity between the North and South Islands.  It is also an important line in providing access to the lowest cost electricity for New Zealand consumers and enables greater competition in the electricity market.
