Future-proofing Your Power Supply

Securing power for Palmerston North

We are currently working on a series of five projects for the Palmerston North community to ensure they have continued security of power supply.

Our task is to expand, rebalance and renew the sub-transmission network and zone substation supply capacity.

Up to the end of CPP – Year One we have:

  • Progressed construction of a new CBD zone substation called Ferguson St, with commissioning in June 2019
  • Installed new 33kV cables from Pascal St, Main St and the new Ferguson St substation, working alongside Palmerston North City Council
  • Installed ducts across the He Ara Kotahi pedestrian bridge in preparation for future cable circuits

In the future, new dual circuit 33kV cables will link the Ferguson St substation to the Linton grid exit point, with the cables running over the He Ara Kotahi bridge. A second power transformer will also be added at Ferguson St substation.

These investments will help to ensure the Palmerston North CBD electricity supply is reliable and keeps up with the future demands of the growing city.

Our Challenge

To cater for the changing energy environment, and most importantly, to deliver your future energy needs, we needed a state-of-the-art solution.

Our Solution

Palmerston North CBD is the second largest central business district we serve, and our largest exclusively underground network.

We needed to future-proof the security of supply to the CBD and surrounding suburbs.

What this Means

Investment of $4.5m in construction of the Ferguson Street substation on the corner of Ferguson and Linton Streets – the first of the new-style fully enclosed substations built in Powerco’s Western region, and one of the largest upgrades undertaken

  • We worked with the Palmerston North City Council to design the building’s external appearance to fit urban planning requirements

Installing new 33kV cables on the Council’s He Aro Kotahi bridge across the Manawatu River – this included laying of underground cable

The 33KV cabling will link the CBD upgrade from the Ferguson Street substation, to the Linton substation

  • He Ara Kotahi Pathway, is a 7.6km off-road pathway and bridge for cyclists and pedestrians – we worked with Council and other stakeholders to install four ducts under the bridge while it was constructed
