The Peat St substation in Whanganui provides customers in the neighbourhood with power supply via three lines. One of those is a full capacity line which can supply the full substation load. When that line has a fault (or requires maintenance) many customers are without power until the line is repaired, with the remaining lines only able to supply to some addresses
We’re constructing a new underground cable between our Peat St and Roberts Ave substations so power can be transferred in the event of a line fault, to increase security of power supply to the city.
Currently Powerco is working with stakeholders to determine the cable route between the substations. Design of the upgrade of the Roberts Ave substation to accommodate the new cable and to provide automated changeover technology is complete.
A single full capacity line at the Peat St substation in Whanganui means some customers lose power if the line experiences a fault.
Construction of a new 33kV underground cable link between our Peat St and Roberts Ave substations.
If there is a transmission fault to the Peat St or the Roberts Ave substations, power can be transferred between the two, minimising loss of supply.
- Increase security of electricity supply, providing reliable power to customers
- Avoid the costs associated with power outages for Whanganui residents, the CBD and the Aramoho industrial area
Construct new substation building

We strive to minimise impact in the design and placement of network infrastructure and we’re still planning and consulting on the route for the new circuit. The circuit will be a mix of overhead lines – which you will see, and underground cable – which you won’t see. You’ll also see a new building at our Putaruru substation, replacing the ageing existing building there.
