Linton purpose-built indoor switchroom

The $5 million upgrade of the Linton substation in now complete.

The upgrade, one of a number of projects to expand, renew and rebalance our assets and ensure our Palmerston North customers have continued security of power supply, saw the once outdoor electrical equipment brought indoors. A purpose-built facility now houses upgraded switchgear and other electrical equipment at the Linton site.

In a separate project totalling $5.1 million, two new underground 33kV electricity circuits – with 41,000m of cable installed – were created from 2019 to early 2022 from the Linton substation to the new Ferguson St substation.

Underground cabling is being installed in mid-2022 between our Main and Ferguson Street substations, after which temporary overhead lines and power poles between the Keith and Main Street substations will be removed.
