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.
