Policy implications now and for the transition
The third and final part of this series of articles from Greg Williams about opportunity costs in electricity markets – this time narrowing in on policy implications.
Case Study – Severe Weather Challenges Day-Ahead Forecasts for 7, 8, 9 September 2023
A bout of severe weather for many parts of south-eastern Australia brought challenging weather conditions which appear to have impacted variable renewable energy forecasts for the NEM. The case study delves into forecast differences on the 7th, 8th and 9th of September 2023.
Research Paper into solar resource intermittency in future (in a climate changed world)
A quick article on WattClarity pointing to some research completed by Shukla Poddar and others about what future solar profile might be across Australia, in a climate changed world.
Darwin to Dili: The contrasting challenges in Timor-Leste during an energy transition
Dan Lee provides this write-up of a recent study tour to Timor-Leste and reflects on lessons learned about how the transition is affecting developing nations.
Transition Fooled?
Through the lens of the GSD2020, Allan O’Neil looks at the much-discussed role of gas-fired generation in the ‘energy transition’ of the NEM’s generation sector
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.
The Southern Annular Mode (SAM) contributes to recent wind drought

Challenges with Emissions Monitoring for Power Generation
Our guest author (Don Sands) compares and contrasts 9 different methods used for measurement of carbon emissions at thermal power stations
Who are the biggest carbon emitters, in the National Electricity Market?
Some analysis of carbon emissions for large generation portfolios in the NEM, and comparison with prior post about wind production levels.
One week into the Carbon Tax – how have emissions changed?
Now that we’re through the first week of Australia’s new Carbon Tax, we thought it would be of interest to have a look at whether there has been any significant change in dispatch patterns across the NEM as a result….
AFR says “Emissions have fallen"! Here’s some more data…
Some analysis prompted by a short article in the AFR talking about a reduction in emissions over summer 2009-10 (with the possible implication being that emissions have turned the corner).
Rising Energy Prices, More Than Meets The Eye
Over the past two days I have attended the annual Energy Users Association of Australia conference, in which I have heard a number of speakers from various walks of life talk about issues that are relevant to large energy users.
Thoughts on a “Diabolical Problem”
