Projects

​We've embarked on a large restoration project to improve the biodiversity and ecological condition of the land and waterways surrounding our Takapū substation.

We are undertaking a project to refurbish the eight HVDC Pole 2 transformers.

We will soon complete the construction of a digital substation laboratory in our Wellington office.

Transpower is considering the concept of Renewable Energy Zones (REZs) and a potential pilot project in Northland. 

A reconfiguration of our network supplying New Plymouth and surrounding area has given us an opportunity to remove some transmission line sections.

As demand for electricity grows in the Waikato, Transpower is considering investment options to ensure the power supply remains reliable.

Transpower has a project underway to replace five towers of its Paekakariki-Takapu Road 110 kV line with new pole structures.

In response to a significant number of generation and load connection enquiries, as well as from a system reliability and security perspective, Transpower and PowerNet have developed a Murihiku Southland Electrification Development Plan.

Sometimes Transpower needs to turn the power off to work on its equipment. Upcoming outages are listed here.
