How many Semi-Scheduled units have taken advantage of the market change that went live on 7th Aug 2023?
Our GSD2023 was released just over 4 weeks ago. Finally today I have a chance to utilise the GSD2023 Data Extract to take a look across all the Semi-Scheduled units (i.e. Wind and Solar) and see who’s been using MaxAvail in their bid to limit their plant availability … and the DUIDs that have not yet used this new facility.
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.
An updated look at Kogan Creek performance in the past 60 days (re industrial action, bushfires, ambient temp, ez2view enhancements, and more)
With ez2view v9.8.5.1 released yesterday (Tue 30th Sept 2023) with enhancements to ‘Generator Outages’ we take the opportunity of some questions about Kogan Creek Power Station to have a look at the usefulness, and possible additional tweaks to make, to this software widget.
Semi-Scheduled Bid MaxAvail – Initial Results
A week’s worth of data provides indications of how semi-scheduled generators are using bid MaxAvail to manage dispatch availability.
What inputs and processes determine a semi-scheduled unit’s availability
It is indispensable to understand how the semi-scheduled unit availability gets produced to optimally manage the critical inputs and comprehend dispatch outcomes. This article explains the key inputs and processes, focusing on the dispatch timeframe.
Implemented: Enablement of bid energy MaxAvail for semi-scheduled generators
The change to use MaxAvail from the energy bid, for semi-scheduled units, was implemented on 7 August 2023.
A closer look at coal-fired generation availability
Tweet at your own peril A quick mea culpa: after squinting at an ez2view layout early this morning I dashed off a tweet suggesting that six of AGL Energy’s eleven coal-fired generation units were offline – three at Bayswater, two…
Another ‘mystery DUID’ puzzle (from Forecast Convergence in GenInsights21)
A second ‘mystery DUID’ puzzle … perhaps more complex than the first … from GenInsights21, for those who like to be challenged in ways like these.
Availability of Black Coal units has suffered through Q2 2021
The volatility that has been with us for weeks now (particularly QLD and NSW), and the dramas unfolding at Callide power station, prompted me to have a broader look at the availability of black coal plant across QLD and NSW, and compare this to prior Q2 periods.
17-year trend of aggregated coal unit unavailability as from the Generator Report Card
Some excerpts from the Generator Report Card to sample some of the analysis we performed to assess various aspects of the ‘dependability’ of coal-fired power stations in the NEM. In this post we highlight availability (or, more precisely, the level of unavailability) as an aggregated monthly volumetric measure trended over 17 years.
Five different aspects of assessing the “dependability” of coal-fired power (in the Generator Report Card)
The framework we used to analyse the extent to which coal-fired power is “dependable” in the Generator Report Card, and the extent to which it’s been changing.
AGL Investor Presentation reports on Portfolio Availability–we take a look for key Stations
AGL released its investor presentation yesterday – several people flagged the availability stats within the presentation (they knew we were looking at aspects of reliability for our Generator Report Card 2018). Hence I take a brief detour and have a quick look.
We’re preparing an extensive “Generator Report Card”, and would welcome discussion (with your pre-orders)
Following from (what we have seen as) an increase in diversity of concerns (and claims) about different aspects of generator performance, we’re leveraging our extensive data set and capabilities to have a deeper look, leading to the publication of a Generator Report Card with data to 31st December 2018. We’d welcome input from those who wish to pre-order their copies now at an initial low rate.
