Here’s a snapshot from NEMwatch at 11:35(NEM time) to record that low levels of ‘Market Demand’.

In the snapshot we see:

1)  We see low levels of ‘Market Demand’ in various locations:

(a)  In Victoria we see the level down at 1,594MW

(b)  In South Australia we see the level down at –26MW

(c)  On a NEM-wide basis, we see the level at 11,718MW

… noting that all of these were above all-time minimums.

2)  As a result of the low level of ‘Market Demand’, we see spot prices squeezed between the rooftop PV juggernaut and the ‘Keeping the Lights on Services’ requirement that kept brown coal running (at least for now).

At 14:33 the AEMO cancelled the ‘Actual MSL1’ event in MN122405:
