Under section 45 of the Electricity Reform Act, the Commission is required to undertake an annual review of, and report to the Minister on, the prospective trends in the capacity and reliability of the Territory's power system.

The Commission publishes an Annual Power System Review to report on power system performance and capacity in the Northern Territory. The Review provides information and analysis of historical and forecast power system performance focusing on the previous financial year and the upcoming 10 years. The Review is prepared with the assistance and advice of participants in the electricity supply industry, other electricity industry stakeholders and consultant reports.
