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.
ASEFS (solar forecasting)
A short article, to record the upgrade of the ASEFS and AWEFS forecasts for Semi-Scheduled (i.e. Wind and Large Solar) units.
Following from the release of GenInsights21, in this article we look at some of what that analytical publication can help us understand, in terms of how the changing market is impacting on the role that renewables will increasingly play in the NEM in the years to come.
Reminded by today’s spikes, here’s a quick look at a similar price spike that occurred yesterday (14:35 on Friday 9th April 2021 in the QLD region).
Three price spikes in the QLD region on Saturday 10th April 2021 help to remind us that how increasingly dependent we are on various machinations of the weather (including, on these occasions, cloud cover and solar output).
As promised in the Intermittent Generation Forum late in 2020, the AEMO has released an important Handbook for operators of Semi-Scheduled (wind and solar) assets.
Yesterday I received a call from the people at PV Magazine who were preparing for the ‘Virtual Roundtables Europe 2020’ event on this week in Germany – i.e. Tuesday evening (now!) and Wednesday evening ‘NEM time’. I’m told the event…
A brief (initial?) look at the impact of yesterday’s dust storm on the output of NSW large-scale solar farms – particularly Nyngan Solar Farm
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.
Four weeks ago, we observed a significant discrepancy between AEMO’s forecast for (what would have been) a record low point for Scheduled Demand in South Australia and what actually eventuated. We’ve now had time to explore further…
Our second Case Study in a recent series, aimed to help us explore ways to continue the pushing the development of ez2view forward, but also shared with readers here on WattClarity. This time about Daydream Solar Farm on Tuesday 3rd September 2019.
