Clutha Upper Waitaki Lines Project

Capacity after upgrade

We need to continually operate, maintain and develop New Zealand's transmission network – the National Grid – to ensure we meet the ongoing electricity needs of New Zealanders.

The Clutha Upper Waitaki Line Project increases capacity on some of our lines between Clutha and the Upper Waitaki Valley to improve electricity supply to Southland during dry periods, and to allow additional generation (should it become available) to be exported from Southland.

The project involves five components with a total approved cost of $197m.  The first two components (which keep Southland secure during dry periods) were delivered in 2015 and 2016 at a cost of around $38 million. 

Project Update

Following commencement of enabling works (initially funded by Contact Energy and Meridian Energy), we have made a decision to continue with our work to complete the remaining works for this project.  While this decision was made prior to the recent announcement regarding the smelter, it underlines the importance of its continuation. 

How it will affect you

We do not expect the local power supply to be affected during this project. We will do our best to keep any other disruptions to a minimum and to keep you well informed of what we're up to.
