Following the release of GenInsights Quarterly Updates for 2023 Q3 we’ve chosen to share here one of the clear challenges for large-scale VRE that is emerging (particularly in 2023 Q3) due to the rise and rise of rooftop PV.
Variable Renewable Energy (VRE)
A brief article as a first Case Study looking at Mon 3rd and Tue 4th July 2023, in conjunction with the compilation of GenInsights Quarterly Updates for 2023 Q3.
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.
Inspired by the recent article by Tristan Edis (who referenced the GSD2022 in analysis of curtailment of some wind and solar farms), Allan O’Neil follows on with more analysis of the two main types of curtailment. Allan differentiates these as ‘forced curtailment’ and ‘economic offloading’
In today’s article (a third snippet from GenInsights Quarterly Update for Q4 2022) we take a look at levels of large ‘Aggregate Raw Off-Target’ (i.e. large collective deviations away from Target), which continue to grow for the Semi-Scheduled category and remind us of that question …
Following recent online discussions, Bruce Miller has produced this in-depth analysis of frequency behavior in th NEM.
Allan O’Neil digs through historic FCAS enablement and utilisation levels to examine whether there is an increasing trend in recent years.
A short note about the release, earlier this week, by the AEMO of the ‘Initial Roadmap’ in the NEM Engineering Framework.
Over 2,000 MW – or around 55% – of South Australia’s firm supply capacity was unavailable last Friday evening (March 12, 2021), along with virtually all of its large-scale renewable supply (a further 1,800 MW or so) but the lights…
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.
David Leitch of ITK Services examines the seasonal effects of Variable Renewable Energy (VRE) and some underlying challenges in this energy transition [this article is based on presentation at ‘Smart Energy Virtual’ on Wed 9th Sept 2020]
