Afternoon spot price volatility on a hot day in VIC and TAS … and bushfire limitations

A quick initial note with a snapshot from NEMwatch at the 15:20 dispatch interval (NEM time) to record the VIC price at $1,485.79/MWh and the TAS price at $842.20/MWh:


A couple quick notes:

1)  The Victorian ‘Market Demand’ is well out of the ‘green zone’ already today (noting the suppressing effect of rooftop PV is still having at this time), driven by high temperatures shown with BOM readings around the state;

2)  The price in VIC and Tasmania is up, as noted above

3)  Also highlighted in the Market Notices window is the MN114955 published at 14:28 with reference to bushfires in Tasmania limiting intra-regional transfer capability:
