Transpower is the owner and operator of New Zealand's National Grid.
Transpower's role is to ensure electricity can be transported from where it is generated to some large electricity users and the distribution businesses that deliver it to homes and businesses all over the country. It's network is made up of nearly 12,000 km of high-voltage transmission lines (and the pylons that hold them) and more than 170 substations and switchyards. Transpower is responsible for building, maintaining and operating this network. Our role is to set the maximum revenue it can recover from consumers to run the National Grid efficiently.
Since 1 April 2011, Transpower has been regulated by way of individual price-quality regulation. The individual price-quality path governs Transpower's revenues for each pricing year, with the paths being reset either every 4 or 5 years. The individual price-quality path was reset for the 2020-2025 regulatory period on 14 November 2019. Read more information on Transpower's price-quality path.
