Prices yo-yo in SA this morning, as installed capacity goes missing

Following yesterday’s warnings about the potential for a tight supply/demand balance in South Australia this week, it was not really a surprise when the SMS alerts from NEM-Watch began buzzing for the 07:20 dispatch interval this morning (NEM time), highlighting that the dispatch price in SA had jumped to $12,199.20/MWh. This has continued through the morning.









Prices see-saw across the (mainland) NEM today

An interesting day in the NEM today, with prices gyrating across a wide spectrum, and across all four mainland regions – on the back of higher demand in Victoria and South Australia due to temperatures there, and supported by transmission issues and other factors.








Background to Winter 2010 in the NEM

Inspired by the price spike experienced this evening, I have spent a little time to put together the background to winters in the NEM.

This will be useful in understanding the context of any other events that occur this winter, and are analysed on WattClarity.
