Options to relieve Central North Island transmission constraints

In a series of reports published in March 2016, we highlighted that transmission capacity from Bunnythorpe to Whakamaru is constrained by the capacity of the 110 kV Bunnythorpe–Mataroa and 220 kV Tokaanu–Whakamaru circuits.  With the decommissioning of thermal generation in the Auckland region, the risk of these constraints binding increases. 

We have identified some low cost options to relieve these constraints in the short-term which include:

Demand response mobile app

Our demand response app is intuitive and makes it as easy as possible for you to help us get the power needed to the right place.

The demand response app explains demand response, allows you to register your interest in the programme, and participate in demand response events.

The demand response app is available on iOS and Android platforms. The app will work with mobile phones as well as tablets. You can download it from the App Store or Google Play.

Load Forecast Accuracy Reporting

Latest Information

We are producing a monthly report comparing the System Operations load forecast (at 1.5 hrs ahead of real-time) against actual load observations.  This report separates conforming load (as forecast) and non-conforming load (as bid by participants).
