Asset Owner Engineering Forum
Transpower hosted its annual Asset Owner Engineering Forum on Wednesday 30 October.
The forum was an opportunity for asset owners and the system operator to discuss various topics at a technical level. The system operator also discussed and shared information relating to asset owner performance obligations.
This year’s forum focused on generation commissioning in the changing landscape of New Zealand’s power system, with particular attention given to clarifying the system operator’s generation commissioning process and accompanying requirements, specifically:
- generation commissioning framework
- commissioning and testing prerequisites
- timelines to ensure the successful commissioning of generation assets for New Zealand.
The slide pack and notes from the forum can be found below:

NZGB tool update workshop
Operations hosted a virtual workshop on 12 June 2024 to take the sector through improvements to the New Zealand Generation Balance (NZGB) tool that will go live at the end of June.
The NZGB tool forecasts whether New Zealand will have enough generation capacity to meet daily peak demand under certain scenarios. It is a critical tool for the grid owner and other market participants to plan essential maintenance outages.
A video of the workshop and slide pack can be found below, and the NZGB tool is hosted on our Operations Customer Portal.

Industry simulation exercises held on 1 & 8 May 2024
The Electricity Authority and Transpower held two industry exercises covering a major power system event on 1 and 8 May 2024.
Wednesday 1 May – for control room operators
- This day was 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 was led by the Electricity Authority alongside Transpower’s communication team and tested communications and interactions from Transpower out through lines companies and retailers to end consumers.
The following report summarises the first day of the pan-industry simulation exercise for control room operators. It details how the exercise unfolded, how participants responded, and includes lessons learned and key takeaways from the exercise.
Please get in touch via [email protected] if you have any questions or feedback on this report, or on any other aspects of the annual pan-industry exercise.

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
