What we're doing
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.
There are three areas of potential constraint in Transpower's North Island network with respect to the amount of generation required to be connected/transported around the island due to New Zealand's progress to a zero-carbon economy. This project is about investigating the capacity of the 220 kV grid between Whakamaru and Wairakei known as the Wairakei Ring. Similar projects are underway with respect to the capacity of the HVDC and Central North Island 220 kV capacity.
