Since 2018, the Utilities Commission of the Northern Territory (Commission) has published an annual Northern Territory Power System Performance Review (NTPSPR), which focuses on overall power system, generation and network performance in the Darwin-Katherine, Alice Springs and Tennant Creek power systems. Where possible and relevant, the NTPSPR compares current performance with historical data to identify trends and industry benchmarks to provide context to the results.

The NTPSPR’s main purpose is to inform the responsible minister, government, electricity licensees and stakeholders on the performance of the Darwin-Katherine, Alice Springs and Tennant Creek power systems, and provide an assessment of generation and network performance in 2022-23, including by highlighting any areas of concern.

Regular reporting on the electricity supply industry helps increase understanding and transparency of issues, with a view to improving planning and investment decisions, understanding of value for money (price compared with level of service) and general performance by holding electricity licensees accountable for their decisions and performance, and the subsequent impacts on customers.

The 2022-23 NTPSPR is prepared by the Commission in accordance with section 45 of the Electricity Reform Act 2000 and is restricted to the Darwin-Katherine, Alice Springs and Tennant Creek power systems, with the Darwin-Katherine power system further segmented into the regions of Darwin and Katherine for some indicators. The 2022‑23 NTPSPR has been prepared with input from licensees through stakeholder consultation.

The 2022-23 NTPSPR continues to transition its ‘look and feel’ from that of earlier reviews, with the Commission revising the focus from a technical and broad-based review of overall power system, network and generation performance, to a review with a narrower scope and focus on standards of service and outcomes of licensee performance as experienced by customers. This change in focus realigned the NTPSPR with the Commission’s role as an economic regulator, noting the Commission is not a technical regulator. However, when and where necessary, the Commission will undertake a ‘deep dive’ on a particular issue or issues, including of a technical nature, either as part of this publication or another publication.
