An assessment of the conductors has shown they are corroding and nearing the end of their serviceable lives.

Our decision is to approve $23.5 million to replace the conductors and to fund Transpower to pay for the expected additional reserve costs of $2 million it could incur as part of this project.

Transpower’s HVDC network transmits bulk electricity between the North and South Islands. Its main use is to transmit hydroelectricity generated in the South Island to the areas of high electricity consumption in the North Island.
