Peat St to Roberts Ave substations

Downer worker with underground cable on Whanganui roadside

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.

That’s why we’re constructing a new underground cable between our Peat St and Roberts Ave substations so power can be transferred between the two in the event of a line fault. The work will increase the security of the power supply to the city and our customers, including the Aramoho industrial area.

We’re also upgrading the Roberts Ave substation to accommodate the new cable and to provide automated changeover technology.
