As alluded to in several recent articles, we have underway a process for updating the ~180 page analytical component included in the Generator Report Card 2018 (released 23 months ago now). We are targeting a release of ‘Generator Insights 2021’ in Q3 2021, and would invite your pre-order.
More time has elapsed since ‘Part 3’ on 24th March – today I’m posting a shorter piece (Part 4) that explains how RHS of the ‘Q>>NIL_CLWU_RGLC’ constraint equation drove down output and led to the price spike on Sunday 24th January 2021.
Looking back at Tuesday 13th April 2021 – a day in which the ex-tropical cyclone Seroja in Western Australia caused some wobbles in rooftop solar PV output in South Australia.
David Osmond’s question on Twitter prompted me to have a look at large wind production overnight.
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).
Caroline Wykamp and Hydro Tasmania’s wholesale team discuss the new ‘virtual storage’ electricity swap contract that they have recently brokered with Renewable Energy Hub.

A threshold for accuracy and threshold for bias has been set to evaluate whether a load’s baseline methodology is acceptable for the Wholesale Demand Response mechanism. Just prior to the…
Guest author on WattClarity (but co-author of the Generator Statistical Digest 2020) uses the GSD2020 and numbers for preceding years to look at how some of the older solar farms are seeing some changes in performance metrics.
Following a number of requests from our clients, we are pleased to note that a GSD2020 Data Extract is now available.
Marcelle extends last week’s comparison of solar farm energy spot market revenue in 2020 by adding in an estimate of the LGC (green certificate) revenue.
Valued team member, Daniel Lee, reviews some of the early references to, and compliments for, the Generator Statistical Digest 2020 – which was released about 7 weeks ago.
It’s taken a while to find the time – but today I’m posting this next analytical piece (Part 3) that seeks to understand what happened on Sunday 24th January 2021 with the NEM-wide SCADA Failure, which contributed to the price spike that occurred in QLD by virtue of what it did to the ‘Q>>NIL_CLWU_RGLC’ constraint equation.
A short article this afternoon to link through to the Preliminary Report published by the AEMO, looking into what happened in South Australia last Friday (12th March 2021).
Which solar farms performed best in 2020? Marcelle compares spot revenue performance across the NEM.
Over 2,000 MW – or around 55% – of South Australia’s firm supply capacity was unavailable last Friday evening (March 12, 2021), along with virtually all of its large-scale renewable…
Two months ago prices spiked in QLD on a Sunday afternoon when AEMO lost SCADA data feed. One month ago AEMO published a preliminary report. In the background we have been taking a look…
