What is the I-NTEM?
The establishment of the Interim Northern Territory Electricity Market (I-NTEM) results from the Northern Territory Government’s decision to reform the energy sector by removing any impediments to competition in the generation and retail electricity markets. The I-NTEM commenced on 27 May 2015.
The I-NTEM provides a framework to facilitate the wholesale arrangements of electricity between generators and retailers in the electricity market. Consumers can then choose to buy electricity from any of the retailers licensed by the Utilities Commission. I-NTEM is designed to align the Northern Territory electricity market to other modernised Australian markets. Initially I-NTEM will only be in effect in the Darwin-Katherine region. This initiative is supported by the creation of a Market Operator (MO) in addition to the existing System Controller (SC).
I-NTEM Market Operator
Within the I-NTEM framework, the MO manages the wholesale exchange of electricity based on the System Control Technical Code. This Code is currently being amended to form the initial market rules for the wholesale electricity market. The MO is responsible for:
- wholesale trading arrangements between generators and retailers,
- registration of all market participants operating in the electricity market,
- market settlements that involves the calculation and issue of invoices to retailers and credit notes to generators, and
- daily publication of market prices and other wholesale trading data.
As the System Control Licence holder for the Darwin-Katherine power system, the Power and Water Corporation was designated as the I-NTEM MO in addition to its existing role as the SC. The SC responsibilities include:
- continuing to manage the dispatch of generating units and power system security
- determine the wholesale market price within the I-NTEM framework at 30 minute intervals.
