Day-ahead demand forecasts will be integral to any future ‘Ahead Market’. We take a look at the current state and accuracy trend of demand forecasts made 24 hours ahead as part of the broader piece of work to feed into GenInsights21.
Using ‘MT PASA DUID Availability’ widget in ez2view to compare unit availability with expectations prior to Q2 2021
Following Saturday’s review of changed expectations for Callide Power Station and Yallourn Power Station, I took a look at aggregate expectation by fuel type. Here’s a belated article with the results.
Carl Daley of EnergyByte examines the ramifications of the Callide Power Station outage and discusses the big losers and winners from the situation.
In order to assist discussions on social media about what’s been happening with Callide C4 over the past 10 years, using the GSD2020 I’ve published some actual detailed performance metrics.
In our development of GenInsights21, we’re exploring ways to also include some analysis of different types of stakeholders in the generation process. In this article we outline a couple (and seek your input).
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.
As alluded to in several recent articles, we have underway a process for updating the ~180 page analytical component included in the Generator Report Card 2018 (released 23 months ago now). We are targeting a release of ‘Generator Insights 2021’ in Q3 2021, and would invite your pre-order.
Guest author, Carl Daley, investigates why big batteries weren’t able to fully capitalise on extreme spot prices in SA on Friday 12th March.
Following recent articles on spot market revenue earned by solar farms in the NEM in 2020, Marcelle takes a look at their FCAS costs.
A threshold for accuracy and threshold for bias has been set to evaluate whether a load’s baseline methodology is acceptable for the Wholesale Demand Response mechanism. Just prior to the…
Guest author on WattClarity (but co-author of the Generator Statistical Digest 2020) uses the GSD2020 and numbers for preceding years to look at how some of the older solar farms are seeing some changes in performance metrics.
Following a number of requests from our clients, we are pleased to note that a GSD2020 Data Extract is now available.
Marcelle extends last week’s comparison of solar farm energy spot market revenue in 2020 by adding in an estimate of the LGC (green certificate) revenue.
Valued team member, Daniel Lee, reviews some of the early references to, and compliments for, the Generator Statistical Digest 2020 – which was released about 7 weeks ago.
It’s taken a while to find the time – but today I’m posting this next analytical piece (Part 3) that seeks to understand what happened on Sunday 24th January 2021 with the NEM-wide SCADA Failure, which contributed to the price spike that occurred in QLD by virtue of what it did to the ‘Q>>NIL_CLWU_RGLC’ constraint equation.
Which solar farms performed best in 2020? Marcelle compares spot revenue performance across the NEM.
Here’s three key insights to listen for this Thursday … when Marcelle Gannon speaks at the CEC’s Large-Scale Solar (virtual) Forum.
David Leitch of ITK Services examines how electricity is losing its share of energy consumption in Australia, while also looking at the main drivers behind lower electricity demand this Summer compared to the previous year.
With UQ recently publishing a performance review of their 1.1MW battery project for the 2020 calendar year, Andrew Wilson posts some extracts from the full report, particularly focusing on the battery’s arbitrage function.
