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.
