Another weekend reviewing progress on the Generator Statistical Digest 2019 (nearing completion) and I thought it would be of interest to share some insights about Loy Yang A unit 1 that jump of the sample page provided to us in yesterday’s draft.
Generator Report Card
RepuTex Energy builds on the Generator Report Card 2018 to provide insights into how different weather patterns impact wind production and the implications for system diversity and portfolio risk.
Last minute complications mean that I cannot speak at today’s “Queensland Smart Energy Summit” (with Jonathon Dyson being an even better substitute). Here are some of the observations I would have liked to discuss with the audience there…
The run of prices at $0/MWh and below is continuing in Queensland region this week as we pass into spring (many dispatch intervals today down as low as the Market Price Floor at -$1,000/MWh). This begs a few questions…
Two pages taken from our Generator Report Card following several different requests from people who attended different events recently where the Report Card was discussed.
A few additional thoughts about proposed changes to the MT PASA process, informed by our conclusions in Theme 14 within Part 2 of our Generator Report Card.
We’ve been invited by the Australian Institute of Energy (AIE) to speak this evening in Sydney about some of the lessons learnt in the process of completing our Generator Report Card. Here’s some context for those who are going to attend (in terms of answers to the 5 frequency asked questions) – and it might help others who are unable to attend, as well.
Last week’s notable under-frequency load shedding in Great Britain following what appears to be the loss of two generation units in quick succession prompts me to publish some of the analysis of aggregate levels of inertia supplied by synchronous generators in South Australia as part of the Generator Report Card.
Given the high level of interest in the Generator Report Card, both the Australian Institute of Energy and the Australian Energy Council have organised separate events (in Sydney in August) providing the opportunity to talk through some of the things we’ve learnt through the process of putting the Generator Report Card together. You’re most welcome to attend!
In terms of diversity of intermittent supplies, we need to understand that we’re not just comparing data series on a scale that runs from “highly correlated” to “random”…
Returning to the challenge posed to readers in April 2019, to guess (or analytically determine!) which of the hundreds of units operating in the NEM showed such a severe limitation in output at high temperatures. It’s not what most people thought it was – far from it!
Here’s some initial details of upcoming informal Q&A sessions in Melbourne (on Tuesday next week!), followed by Adelaide, Brisbane and Sydney – where we’d look forward to meeting with those interested 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.
A summary of some comments that we’ve seen in the first few days of the Generator Report Card
For those who have already pre-ordered their copy, this is how you can access – and for those who have not, but would like a copy, this is how to arrange this as well.
Worth sharing the level of detail we’re going to, in Part 3 of the Generator Report Card (5 parts in total), where we have assembled millions of data points into a single page summarizing the last 10 years of performance of a particular generation unit. There’s a page for each operational unit (327 in total).
We’re taking a much, much deeper dive into generator performance at high temperatures (for all DUIDs operational across the NEM) to see how each one of them, individually, is affected by high temperatures. Guess which one this “mystery DUID” is and we’d look forward to providing some form of prize…
Sharing a trend of daily capacity factor across all Large Solar plant (post commissioning) in the NEM (preliminary analysis for our Generator Report Card).
Last week the AEMO released a draft of the Marginal Loss Factors (MLFs) that would apply to both generation and loads connected to the NEM. This page on the AEMO…
A quick article highlighting how the trend in aggregate number of unit starts, across the whole of the NEM, highlights the scale of one of the core underlying changes (and challenges) facing us in the NEM’s energy transition.
