Our Grid

Transpower is committed to providing New Zealand with a safe, reliable, cost-effective and future-focused grid. 

We look after more than $5 billion worth of assets that span the length and breadth of the country. We will match infrastructure to need over time and our asset management framework plans for this.

  • 30,000: properties that our assets are situated on
  • 25,000: transmission towers
  • 11,000: kilometres of lines
  • 174: substations
  • 2: National Grid Operating Centres (NGOC)
