Consultation on two draft determinations of causer for under-frequency events

  • Compliance

We are seeking your feedback on two draft determinations of causers for under-frequency events that occurred on 30 July 2022 and 7 October 2022.

The normal frequency band in New Zealand is between 49.8 and 50.2 Hz. An under-frequency event occurs when the frequency falls below 49.25 Hz because of a loss of more than 60 megawatts injected into the grid.

The Electricity Authority is required to consult on its draft determinations with every generator, grid owner and other participant substantially affected by the under-frequency event.

Consultation is open until 5pm on Tuesday 29 August 2023.

Have your say - view the consultation.
