A brief note about the (also short) notice from the AER relating to two rule change proposals which it has been asked to propose by the COAG Energy Council
Tom Geiser, Senior Market Manager at Neoen, discusses the merits of proportional, relative control on the issue of small solar curtailment.
Analysis compiled to explore what the impact was of the unusual weather pattern (extensive cloud cover and cold temperatures) seen across a large part of Queensland on Saturday 23rd May 2020.
A few quick words, about the challenges inherent in assessing the benefits of diversity too superficially. It clearly does have some benefits, but it’s not a Magic Wand.
On Thursday 21st May, Marcelle Gannon and Jonathon Dyson jointly shared a large number of insights and tips to help those interested in developing and/or operating Large Solar Farms in the NEM maximise the value they receive. Useful also for those interested in Wind Farms (i.e. any Semi-Scheduled plant), and also hybrid operations using Batteries.
In a sneak preview from the “Maximising Value in the NEM” webinar this Thursday, Marcelle looks at the changing distribution of spot prices in QLD.
This is the 3rd of 4 Case Studies to follow on from the main article (summarising results across 105,120 dispatch intervals through 2019 for ‘all Coal’ and ‘all Wind’ groupings). In this case, let’s look at the ‘worst’ case, in aggregate, where wind units under-performed compared to dispatch targets.
Guest author, Andrew Wilson, presents a case study of the performance and results from the University of Queensland’s 1.1MW Tesla Powerpack system during Q1 2020.
Following on from the article posted on the day, here’s a focused look at what can be seen in (‘next day’ public) data for Yarranlea Solar Farm on Friday 1st May 2020 – a day that saw negative prices through many half-hour trading periods in Queensland, and Large Solar farms cycling as a result.
This is the 2nd of 4 Case Studies to follow on from Tuesday’s main article (summarising results across 105,120 dispatch intervals through 2019 for ‘all Coal’ and ‘all Wind’ groupings). In this case, let’s look at the ‘worst’ case, in aggregate, where coal units over-performed compared to dispatch targets.
Following on from Tuesday’s main article (summarising results across 105,120 dispatch intervals through 2019 for ‘all Coal’ and ‘all Wind’ groupings), this is the first of 4 x Case Studies that look at each of the extremes in outcome. This one is the dispatch interval featuring the greatest over-performance, collectively, across all coal units through 2019.
Recent invitations (from COAG Energy Council and AEMO) prompt some further analysis of the data set assembled for the GSD2019 in order to understand more about one of the challenges in balancing Supply and Demand in the NEM 2.0 world.
Ben Willacy of ITK Services provides his quarterly update on renewable project connection, commissioning, construction and commitment activity for Q1 2020.
Quick notes about a new peak in wind farm output across the NEM that occurred on Friday evening last week (1st May 2020).
Three main factors contributed to the spot prices in Queensland dropping underwater today for a number of hours – with some factors suggesting this might be the pattern for the coming week…
