Decisions on 30 July and 7 October 2022 under-frequency events

In August 2023, the Electricity Authority consulted on its draft determinations for two under-frequency events on 30 July and 7 October 2022.

Our final determinations are that:

• Genesis Energy Limited was the causer of the under-frequency event on 30 July 2022
• Transpower New Zealand Limited was the causer of the under-frequency event on 7 October 2022.

If a substantially affected participant would like to dispute these final determinations, they can provide a written notice to the Rulings Panel within 10 business days after the publication of this decision.
