What’s up with the fleet of 16 x coal-fired units in NSW?

Following a week where several days saw price volatility in NSW (with this being so extreme that Reserve Trader was triggered on Thursday 17th December) we’ve taken a look at the comparative performance of coal units across the NEM (and particularly in NSW) compared to prior years.



PPAs aren’t as easy as they used to be!

This is the fourth of a short series of video snippets extracted from the 17th September 2020 presentation by Marcelle Gannon and Jonathon Dyson for the Clean Energy Council entitled ‘Maximising Profitability in the NEM’ for Wind Farms.

Does the NEM need to be redesigned?

Guest author Stephen Wilson chaired an ‘ESIG Down Under’ conference webinar on ‘Designing the Energy Markets of the Future’. Whilst introducing the session, Stephen presented a diagram that helped to clarify the combination of different time horizons that need to be considered in holistically describing ‘the Market’. It will be of interest to WattClarity readers.






Extrapolating from the trend of ‘Aggregated Raw Off-Target’ results, to yield some clues to what the future might hold … and one challenge for NEM 2.0

There’s a clear clustering of cases in 2019 – what does it mean?


Striving to understand the underlying challenges with Semi-Scheduled generators (re AER Issues Paper)

Prompted by the recent AER Issues Paper (submissions on that due today – Friday 24th July) but also aware that I’ve not yet published some broader thoughts in response to the ESB’s requests for input into their Discussion Paper on the Two Sided Market concept, I’ve posted some further thoughts. These have been informed by a longitudinal analysis of Aggregate ‘Raw Off-target’ values across all Semi-Scheduled plant.
