A very short article with a snapshot from NEMwatch at 18:00 (NEM time) to record some evening volatility in South Australia:
Note that:
0) Spot price in SA at this time is $1,144.83/MWh, and climbed to the Market Price Cap ($16,600/MWh) afterwards.
1) Prices have been elevated in South Australia (i.e. $300/MWh or up) through daylight hours.
2) The NEM-wide ‘Market Demand’ is at 30,485MW at this point, and
3) (By the colours) we can see regional demand is somewhat elevated in SA, VIC and QLD (with reference to the historical range).
That’s where the article initially ended…
