The Project
Hokonui Line Project
This project will improve the security and capacity of the local electricity network and create economic growth in Southland.
To support Fonterra's growing electricity needs at Edendale, a new 110kV above-ground power line is being built. This project will improve the security and capacity of the local electricity network, helping to power major decarbonisation initiatives such as the UHT plant and future decarbonisation projects.
The project involves building a 12.5-kilometre, 110kV overhead distribution line that will run between two new substations - one located on Cuttance Road and the other at Fonterra's Edendale site.
These substations will enable a more reliable and resilient power supply to the area, ensuring the site is well-positioned to meet both current and future electricity demand.
Hokonui Line will play a vital role in helping Fonterra meet its sustainability goals while ensuring a secure and reliable power supply to support ongoing operations at Edendale and beyond.
What it means for local residents
As with any major infrastructure project, there will be some disruption during the construction of the new line. This could include short periods of increased activity, noise, or restricted access in areas close to the construction route.
We're committed to keeping residents well informed and will provide plenty of notice ahead of any work that may affect you. We'll also work hard to minimise any inconvenience and ensure the community remains well across the project as it progresses.
