Directions to SA generators – 1 December 2016

On 1 December 2016, AEMO issued directions to three Market Participants in South Australia to restore power system security in the National Electricity Market (NEM). The requirement to intervene for directions arose after the interconnection between South Australia and Victoria was severed after the Heywood Interconnector tripped. This resulted in South Australia separating from the rest of the mainland NEM, with no synchronous connection to the NEM grid.

Where the Australian Energy Market Operator (AEMO) intervenes in the NEM through the use of directions, AEMO must publish a report in accordance with National Electricity Rules (NER) clauses 4.8.9(f) and 3.13.6A.

The NEM Event report below satisfies those NER obligations and is based on information available to AEMO at the time of publication:

In accordance with NER Clause 3.15.7B (c)(1), AEMO is required to appoint an Independent Expert to assess and determine the additional compensation claims for the Directed participant that exceeds the $20,000 threshold and exceeds the $100,000 aggregate threshold.  

Further information on the appointment and reports completed by the Independent Expert(s) relating to the reporting period of 1 December 2016 is accessible from the following page(s):
