System Control oversees the safe, secure and reliable operation of the Territory’s regulated power systems.

System Control has a statutory role in monitoring and controlling the operation of the power systems in the Northern Territory. It is responsible for overseeing the safe, secure and reliable operation of the Territory’s regulated power systems.  

The System Control Licence issued by the Utilities Commission determines Power and Water's statutory obligations. 

System Control is responsible for the real time operations, operations planning, power system technical assessments, incident reviews, and operational and technical regulatory reporting.

The Interim Northern Territory Electricity Market (I-NTEM) oversees the wholesale arrangements of electricity between generators and retailers in the Northern Territory.

As the electricity market evolves, more energy providers will join, particularly those with renewable energy solutions. System Control must work towards levelling the playing field to encourage new entrants into the market who can produce energy safely, securely, reliably and in an environmentally efficient manner.

System Control and the Market Operator work towards implementing new procedures, redefining processes and improving communication with market participants in the Interim Northern Territory Electricity Market (I-NTEM) and the other regulated regional electricity networks.

The goal of System Control and the Market Operator is to ensure reliability and safety of the networks while encouraging new competition and improvements in machine efficiency.

Power and Water Corporation is the Market Operator within the I-NTEM.

The System Control Technical Code sets out operating protocols, arrangements for security dispatch, arrangements for disconnection, and any other matters relating to monitoring, operation and control of regulated power systems.

The code provides rules for the operation of the Interim Northern Territory Electricity Market. Amendments to the code are made by the Power System Controller and are subject to approval by the Utilities Commission.

Both entities are required to consult with stakeholders in accordance with current regulatory requirements.

This Schedule of Audit and Inspection is issued pursuant to System Control Technical Code (SCTC) Clause 6.22.1 (e), covers the 2024/25 Financial Year, with a proposed Schedule covering the forward four year period.

This Schedule was established with reference to the requirements laid out in Clause 6.22.1 (c).

System constraints are the result of system parameters. System constraints are designed for the secure operation of the power system within the technical envelope.

There are two ring-fencing regimes that apply to Power and Water under different Authorities, the Australian Energy Regulator ring-fencing guideline and the Utilities Commission Northern Territory Ring-fencing Code (Code).

The objective of the NT Electricity Ring-fencing Information Procedure is to describe the minimum requirement of how Power and Water Corporation’s (Power and Water) Prescribed Business (System Control), performs System Controller functions at Power and Water. Clause 3 of Schedule 1 of the Code outlines the procedures for handling confidential and designated information within Power and Water.

This procedure ensures that employees involved in System Controller functions manage information in a way that prevents giving the Regulated Business (RCB) a competitive advantage. The procedure also defines when confidential information can be disclosed and ensures that any designated information shared with the RCB is equally accessible to its competitors.
