With the release of the Generator Statistical Digest 2020, Marcelle Gannon takes a look at how it can be useful for identifying and exploring different patterns of generation.
An unfortunately timed significant slump in output across all Wind and Large Solar plant in NSW was another of the factors contributing to the price volatility seen in NSW last week.
