Our role

We are responsible for operating the Northern Territory’s electricity market and power systems. The operation of the electricity market and NT power systems is governed by a range of national and Territory legislation including a national set of energy laws and rules and NT legislation as well as guidelines, standards and procedures.  Under the national laws the previous System Control and Market Operator functions are now referred to as the Northern Territory Electricity System and Market Operator (NTESMO).”

This includes:


The Interim Northern Territory Electricity Market (I-NTEM) provides a framework to facilitate the wholesale exchange of electricity between generators and retailers. Within the I-NTEM framework, Power and Water manages this exchange based on the System Control Technical Code, Electricity Retail Supply Code and the National Electricity Rules as in force in the Northern Territory (NT NER).

The Northern Territory has adopted full retail contestability, which means consumers can choose to buy electricity from any of the retailers licensed by the Utilities Commission .
