Industry simulation exercises to be held on 1 & 8 May 2024
The Electricity Authority and Transpower are planning an industry exercise of a major power system event on 1 and 8 May 2024.
The industry exercise will run over two days:
Wednesday 1 May – for control room operators
- This day will be led by the system operator to test grid emergency processes and interactions between the system operator and generators, lines companies and direct connect industrial customers.
Wednesday 8 May – for digital communications/social media/customer leads
- This day will be led by the Electricity Authority alongside Transpower’s communication team and will test communications and interactions from Transpower out through lines companies to retailers and end consumers.
We hope that control rooms for all power system participants will join us for the first day of the exercise. Control rooms should email [email protected] for more details and to register interest.
Communications and customer leads should email [email protected] to take part.
We run various workshops/webinars each year of items that are topical to the industry, below are presentations from previous workshops from the last five years of workshops.

Security of Supply and evolving context – 25 July 2023
We presented the Security of Supply Assessment for 2023 at this extended System Operator Industry Forum.
The annual assessment uses electricity demand and supply forecasts to assess whether there will be enough energy and capacity to meet New Zealand’s electricity demand over the coming decade. It is based on existing generation as well as planned generation at different stages of the development process.
We also presented a new Evolving security of supply assessment in New Zealand paper that looks at how our thinking about a secure electricity supply should evolve as we move to a low or zero carbon future.
The Security of Supply presentation starts at the 7-minute mark and continues for the rest of the hour.
Winter 2023: Managing winter peak capacity risks - 30 May 2023
We took industry through our approach to managing winter peak capacity risks in an extended edition of our fortnightly System Operator Industry Forum. The session presented:
- new information resources available to the market for winter
- new processes for coordinating market participants in the case of low residual generation situations and potential grid emergencies
- a refresher of existing information and processes for informing and coordinating the market
We also presented our approach for communicating potential electricity supply shortfalls with the public, including a reminder of how we will use the Major Power System Event Contact List we set up last year.
Winter 2023: Use of 'discretionary demand' control 17 May 2023

Asset Owner Industry Forum 2021
The Forum is an annual gathering hosted by Transpower in its role as System Operator (SO) for New Zealand’s generation and distribution asset owners. It offers attendees an opportunity to interact with the SO and other asset owners and encourage collaboration at a technical level. It also allows the SO to discuss any challenges you may have in meeting the required Asset Owner Performance Obligations.
The theme for this year’s forum was Embracing New Connections with an aim of informing, clarifying and improving the connection process and providing an overview to the industry of exciting projects that are currently in-flight.

Asset Owner Industry Forum 2018
The theme of this forum is Fault Ride Through Capability, and Companion Guide for Asset Testing.
The yearly Asset Owner Industry Forum is to discuss emerging issues, share knowledge, and provide guidance on good practice amongst asset owners and the System Operator.
There has been considerable interest from industry participants in getting more detail and clarity about how to demonstrate compliance with the fault ride through requirements of the Code. In the morning session we will summarize the requirements, then have an in-depth look at a study approach including some example studies. In the afternoon session discussion will be on proposed changes to the Companion Guide for Asset Testing with specific reference to guide for generator testing and new technologies and the coordination of Code development to align with their anticipated deployment.
