A price spike in SA on Wednesday 23rd February reminds us of a price spike in NSW on Monday 21st February … one due to coal, the other due to solar … but both illustrating *the same* underlying dynamic.

A short look at this afternoon’s pricing volatility in the South Australian region with what appears to be coincident trips at 2 related Large Solar Farms.
Out-of-the-blue, the price spikes up near $10,000/MWh in South Australia on an otherwise ‘boring’ day … a sign of what we should expect increasingly in future?
This 19th Case Study in the series investigates one dispatch interval showing extreme Aggregate Under-Performance across all Semi-Scheduled units on Friday 5th April 2019.
This 15th Case Study is longer than the earlier 14 as it deals with 4 discrete instances of extreme level of collective under-performance, and 1 instance of over-performance, all within a 4-hour timeframe on the same day. A day which appears to have had widespread weather activity affecting the output of BOTH Wind and Solar across 3 Regions. A challenging day!
Two examples where units (in these cases Semi-Scheduled) appeared to disregard dispatch targets.
