A quick synopsis of some market reforms at the AEMC relating to system frequency.
Observations of differences in system frequency in the Mainland NEM (comparing 2019 to 2021)
One of the many data sets being crunched as part of our analytical efforts underpinning the development of ‘GenInsights21’ is system frequency. In this short article today, we share some initial observations on how it has been changing.
FCAS goes from fast to very fast
Just under 3 weeks ago (on 22nd April 2021) the AEMC published a draft determination that would establish ‘Fast Frequency Response’ as an additional (i.e. 9th and 10th) FCAS service in the NEM. We take a brief look.

Following up to AEMO’s recent Intermittent Generator forum, Marcelle looks at the challenges for wind and solar farms in providing consistently good plant availability information to AEMO and the value of transparency of this data.
Making demand response work with negative prices
A recent development over in the WEM (paying energy users to consume, when there’s too much solar and wind) highlights the lack of foresight in the NEM … where we’ve implemented a significant reform (yet to start) that will do nothing to address negative prices.
