Friday, 30 December: Top prices of
$2800.09-$4187.69/MWh in multiple spike intervals in NSW, Vic, SA, Qld
and Snowy as heatwave hits Adelaide and Melbourne
Top prices of between $2800.09-$4187.69/MWh were recorded in multiple
spike intervals in NSW, Victoria, South Australia, Queensland and Snowy
on Friday, 30 December.
SA has 23 spike intervals: South Australia had spikes in 23 of
the 48 30-minute trading intervals. NSW, Victoria and Snowy had spikes
in 11 trading intervals and Queensland in seven.
Heatwave causes demand surge: The spikes occurred on a day when
system-wide maximum demand surged by 1650MW (5.9 per cent) to 29,780MW,
largely due to big increases resulting from the heatwave in South
Australia and Victoria. Adelaide had a top temperature of 41 degrees
and Melbourne 39 degrees.
Another direction to Directlink: There were also continuing
problems with NSW supply and NEMMCO directed the Queensland-NSW
Directlink interconnector to be available for dispatch, as well as
offloading the 132kV feeder 9W2 to maintain power system security.
NEMMCO also forecast a lack of reserve level one (LOR1) for three hours
30 minutes in South Australia and for one hour in NSW.
