Direction to QLD Generator – 22 May 2018

On 22 May 2018, AEMO issued a direction to a Queensland Market Participant to maintain power system security. The need for the direction was to limit the flow at the Ross cutset after multiple network elements at the Ross substation in north Queensland tripped simultaneously. 

Where the Australian Energy Market Operator (AEMO) intervenes in the National Electricity Market (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:
