Commissioning

The Commissioning workstream sought to implement changes to the commissioning process to improve speed and efficiency of plants reaching full output, without compromising system security or reliability.

The framework was trialled on a series of active projects, and learnings have been incorporated into a Commissioning Guideline. In addition, a Commissioning Toolkit, including sample templates and test descriptions, has also been created to assist Proponents in developing their commissioning programs in accordance with the new guideline.  

The Guideline and Toolkit aim to:

• Deliver a consistent, efficient NEM-wide approach under NER 5.8 without compromising power system security.
• Clarify roles and responsibilities for commissioning steps.
• Guide assessment of plant impact to optimise hold points and commissioning scope.
• Support flexibility for construction schedules and resource variability.
• Introduce stability testing checkpoints to reduce test repetition and reporting burden.
• Create efficiencies for proponents, NSPs, and AEMO, enabling projects to reach full output sooner

Background

In 2023 a review of Commissioning Practices within the NEM was completed by independent consultant, Avoca Energy.

Following industry engagement and initiative reviews, the consultant reviewed and collated the feedback and learnings connected to commissioning practices. Independent consultant, DIgSILENT, was then engaged to collate the data and identify where efficiencies and/or improvement opportunities existed for incorporation into the connection process map.

The independent review of Commissioning Practices can be found here:

Webinar

AEMO hosted a webinar on 10 February 2026 to introduce and explain the Commissioning Guideline and Commissioning Toolkit Resources, and how they can be used to support Proponent’s projects.
