Remember that (before some readers jump on their preferred hobby horse), not only does high temperature significantly drive electricity demand higher (e.g. above 33,000MW forecast across the NEM for Monday), it also deteriorates the performance of pretty much any generation supply source.  To be clear…

1)  Coal, gas and liquid fuelled plant are worse in high temperature

… limits peak output and efficiency (not so clear that it makes them less reliable, though).

2)  Wind and solar can also also both be worse in high temperature

3)  Batteries are also worse in high temperature

4)  Network limitations are also more extreme in high temperature.
