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.

We are increasing capacity on some of our lines between Clutha and the Upper Waitaki Valley to help improve electricity supply southwards to Southland during periods of low hydro inflows. The project initially involved five different line sections, with a total cost of $197 m.  However, following periodic reviews since 2012 we now do not consider that there is sufficient certainty regarding new generation or load in the lower South Island that would provide a justification to proceed with the remaining three sections of work at this time.


Why we're doing it

During dry years this project will help improve electricity supply southwards to Southland.

How it will impact your electricity bill

For the complete project, we expected the cost of the project on all New Zealand consumers to be up to about $3.10 a year (or about 25 cents a month) for an average consumer.  With three components of that project not proceeding at this time, the cost will reduce further.

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.
