Security of Supply - Outlook to 2030 : Workshop

A workshop was held in Wellington and run on-line on the 28 July 2020. The workshop covered our annual medium-term security of supply assessment as well an interactive session to explore and discuss a range of security of supply risks and issues.

Workshop Topics

Workshop slide pack [ pdf 1.2 MB ]

Topics covered:

  • Introduction and summary of last year's Security of Supply Annual Assessment.
  • Gas generation: future fuel supply constraints?
  • Security of supply workshop. Interactive session to discuss medium-term security of supply issues and risks and how these can be captured in our annual medium-term security of supply assessment



This year’s forum is on the successful commissioning of assets, with the aim of clarifying, informing and improving the commissioning process.

Workshop Topics

Held in Wellington on 2 October 2019.

Full Slide Pack [ pdf 4.87 MB ]

Summary Notes [ pdf 555.85 KB ]

Topics covered:

  • Asset connection assessments requirements – provide connection information ahead of time to remove ambiguities and uncertainties when moving through the commissioning process.
  • Distributor connected generator - the nature of the generator connection can impact on the System Operator’s ability to meet its Principal Performance Obligations regardless of the connection type the Code still applies in its entirety.
  • Asset owner test data – Asset owner performance obligation compliance and ancillary services contract check. 
  • Fault ride through – provided fault ride through assumptions template but still a work in progress as more information needs to be considered.
  • Maranga Ra, New Zealand’s Largest Solar Farm – directly connected to the Refining NZ. Some code requirements are difficult to follow for solar and such connection.
  • Waipipi Wind Farm, the Connection Journey – challenges include some code requirements that are hard to find, overzealous IT systems, modelling for fault ride through, and generator models.
  • Solar and battery energy storage systems – design approach being considered; future work stream, and hot-fix work that is already underway.


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.

Workshop Topics

Held in Wellington on 5 September 2018.
