In Part 2 of this Case Study, we look at those 15 x Semi-Scheduled units highlighted with large deviations (mostly under-performance) at 17:05 on 27th October 2022 in order to understand more.
Dan Lee explains why capacity factor could be becoming an increasingly less useful measure for comparing how different solar farms are performing and begins an exploration into some of the factors in play when trying to conduct more comprehensive analysis into generator performance.
In Part 1 of this Case Study, we start to look at the large collective under-performance across all Semi-Scheduled units (i.e. Wind and Large Solar) at 17:05 on 27th October 2022. More to come in subsequent parts…
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 …
This second excerpt from GenInsights 2022 Q4 Update highlights some of what’s seen in terms of the performance of coal units.
This first excerpt from GenInsights Quarterly Update for Q4 2022 looks specifically at the trended level of adoption of self-forecasting for Semi-Scheduled Solar Farms in the NEM. This article on Monday 26th February 2023 precedes some changes AEMO might make on Tuesday 27th February 2023.
Allan O’Neil digs through historic FCAS enablement and utilisation levels to examine whether there is an increasing trend in recent years.
Allan O’Neil provides an explainer about how small deviations in supply and demand are managed in the NEM, in order to help us understand the apparent swings in frequency that we noted in QLD last Friday.
David Leitch of ITK Services provides his top insights from the GSD2022, which he has used to look into generation mix, constraints and firming.
Dan Lee uses our hot-off-the-press GSD2022 to examine the Q4 revenue figures that Genex Power recently released for Jemalong Solar Farm.
Guest author, Allan O’Neil, takes the release of the GSD2022 as an opportunity to take a look at the past 10 years of performance of the four-unit Liddell Power Station (one unit closed in 2022 and three to close soon in 2023), contrasting against two other black coal-fired stations.
An article on RenewEconomy this week (about some analysis by analysts at ANU) coincided with our review of sequential drafts of the GSD2022, and prompted this article to have a look at some reported lost production at a number of solar farms across the NEM.
Two media articles (in the Guardian and the Australian) prompt a quick article, utilising an in-development copy of the up-coming GSD2022.
One of the metrics we introduced into GenInsights Quarterly Update for 2022 Q3 was a long-range review of IRPM (Instantaneous Reserve Plant Margin). In this article we share a little of what we found.
The Griffith University (by Joel Gilmore, Tim Nelson and Tahlia Nolan) study mentioned in earlier RenewEconomy article is now accessible on the Griffith University website here.
On Monday 31st October 2022 we released GenInsights Quarterly Updates for Q3 2022 – second in the expanding series, following customer requests for updates of GenInsights21
A quick note to mark Thursday’s release of the QED for Q3 2022 by the AEMO
It’s under 2 weeks since the Queensland Government released its much-awaited Energy Policy. Some reports into the modelling behind this (from EY-ROAM) has been released.
Following the published note of scepticism/concern about the energy transition from several industry CEOs in the AFR on Friday, we take a quick look at the replacement capacity needs just for Loy Yang A power station to illustrate the enormous scale of the challenge.
It’s taken longer than expected – but today I’ve posted this article that goes some way to answering the question ‘to what extent was solar production disappointing through periods of Q2 2022?’
