In her first article for WattClarity, Marcelle looks at questions raised in the recent summer on the forecasting of performance at high temperatures of wind and solar generators, and asks how AEMO and industry can work together to improve this.Read More
An article published by AEMC on the ‘value of dispatchability’ provided the spur to return to our intention of freely sharing insights gleaned from the Generator Statistical Digest 2019. Today’s article highlighting the value of dispatchability.
Last week saw more in a growing series of exits, and asset write-downs, amongst new entrants in the supply of renewable energy within the NEM. Today on WattClarity I ponder whether we have been setting them up to fail due to the nature of support provided to these new entrants. What is your perspective?
Review of extremes in ‘Raw Off Target’ performance through 2019, with the Generator Statistical Digest 2019
Using the (hot off the press) Generator Statistical Digest 2019, we take a look across all 304 DUIDs to see how they performed through calendar 2019 in terms of large excesses in ‘Raw Off-Target’ in both directions. These results suggests implications for the future…
Guest author, Ben Willacy, takes a first look at the Generator Statistical Digest 2019 and highlights a few initial observations relating to the performance of wind, solar and storage in this energy transition.
Guest author, Allan O’Neil, takes a look, via the GSD2019 (released today), at the four different headwinds facing solar farm developers and operators operating in the NEM.
Perhaps missed amongst all the bushfire-related action in the NEM, the SA Minister for Energy last week initiated the Retailer Reliability Obligation. Guest author Allan O’Neil tries to come to grips with what this means, and what happens next?
AEMO speaks directly to Wind and Solar Farm operators – please alert us to temperature limitations on your assets
In what seems (to me) to be an extraordinary measure, AEMO speaks directly to the operators of Wind and Solar assets in the NEM, asking them to update the AEMO on the high-temperature limitations of their plant. How did it come to this?…
Guest author, Tristan Edis, looks particularly at the Queensland Region of the NEM, and an almost complete stop in the development of new renewables projects.
Today’s guest author, Ben Willacy, examines current trends in commisioning activity and new grid connections for new supplies in the NEM.
42 months after I posted some initial thoughts about “the opacity of rooftop PV” it seems that – when viewed in certain ways, discussed here – the problem is actually getting worse, not better.
Readers at WattClarity might recall that we have asked the question above a couple of times in recent weeks – and a big thanks to those who responded already! We’re…
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.
Better late than never (perhaps?) today I post a few thoughts about the AEMC’s proposed draft rule change for the incorporation of NegaWatts into centralized dispatch.
Our guest author Maria Cahill, offers insights and details lessons learnt over the past two years since moving to Melbourne from the UK to set up K2 Management’s Australian office.
Some operations at Stanwell Power Station unit 1 in the past couple weeks caught our attention, and are presented as a useful illustration of some concepts related to flexibility of power generators (in this case, coal-fired power).
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…
Rapidly growing solar PV output has been widely tagged as the cause of low and even negative prices in Queensland. But in any market it’s the behaviour of ALL participants that determines price outcomes. Guest author Allan O’Neil takes a closer look at recent NEM bidding.
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.
