Network Spend


The Taranaki region is Powerco’s heartland. Our network covers the northern and central area, with Hawera to Warea defining the southern limits. We supply the urban centres of New Plymouth and Hawera, along with large intensive dairy farming and oil and gas exploration sites.

The local terrain and climate are generally pretty good for our network assets in terms of construction, access, maintenance and life expectancy. There are exceptions, of course. In coastal areas, corrosion can affect assets as far as 20km inland. Severe weather events such as storms and localised tornadoes can also have a big impact on our network.

Due to its advancing years and the declining health of many overhead lines, our Taranaki network needs some extra love, in the form of extensive asset renewal work.

Our customers in rural Taranaki will have seen the beginning of our network upgrade work between Inglewood and Midhirst from 6.6kV to 11kV. In October, we replaced the 85 poles on York Road, and the remainder of the project will be spread over the coming years.

Our team has worked hard to power up New Plymouth’s new underground cable link between the Carrington Street and Moturoa substations. The $16m project was completed in December and involved 7km of cable laying, building a new substation at Moturoa and upgrading the Carrington Street substation.

It was great to give back to the Taranaki community over the holiday period and support two free events, Christmas at the Bowl and the TSB Festival of Lights.
