Benchmarking large-scale solar PV performance
Lachlan McLeod of Ekistica writes this short article following the recent release of an ARENA report looking into performance ratios used to compare solar pv operations.

Rooftop PV output during QLD’s heatwave week 2022 – Part B
In this article we look more closely at 1st and 2nd February 2022 – and particularly at where and when the changes in rooftop PV occurred, narrowing our assessment to south-east Queensland regions. It follows on from Part A which inspected how Queensland rooftop PV output varied at the state level.
November a volatile month for Australian solar power
Ben Domensino of Weatherzone discusses an extreme month of wet weather across Australia during November, and its impact on solar generation.
The volatility seen through Q2 2021 was also a product of timing of solar production
Only ~11 weeks after the end of Q2 2021 we’re still exploring details of the extreme price outcomes. Here’s some of the ways in which solar PV played a significant role in the price outcomes delivered.
Cyclone in Western Australia douses solar production in South Australia on Tue 13th April 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.
Large-scale solar farm revenue in 2020 part 2 – considering LGCs
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.
A Comparison of Large-Scale Solar Farm Revenue in 2020
Which solar farms performed best in 2020? Marcelle compares spot revenue performance across the NEM.
Heavy rain across Victoria squashes Small and Large Solar on Friday 29th January 2021
Short article today observing higher Scheduled Demand in VIC – which appears to be in large part due to state-wide suppression of solar PV production with heavy cloud and rainfall.
Yesterday’s unexpected loss of ~500MW of rooftop PV in South Australia (another type of Contingency event – Credible, or Non-Credible?)
Wednesday 13th January 2021 was a busy day in the NEM, with a couple of different events occurring. In this article we explore a sudden and unexpected drop in output across both rooftop PV and large-scale solar in South Australia that delivered both price spikes, and also broader questions about emerging challenges for the grid (and market).
Maximising the benefit of renewables with an intelligent energy management system
Following a presentation to the EESA in September, Dr Robert May and Ashley Nicholls from SA Water have written a case study detailing the sophisticated energy management system that they have developed over the past 7 years.
Amperon report for AEMO released, exploring attenuation of Large Solar production with bushfire smoke
A short article today, highlighting the release of this Amperon report for AEMO looking at the way in which the performance of some Large Solar Farms in the NEM were affected by bushfire smoke through summer 2019-20.
Extrapolating from the trend of ‘Aggregated Raw Off-Target’ results, to yield some clues to what the future might hold … and one challenge for NEM 2.0
Following on from Friday’s article (which considered the AER Issues Paper) this article delves into more detail of those extremes of ‘Aggregate Raw Off-Target’ across all Semi-Scheduled units that have been recorded over the past 10 years. There’s a clear clustering of cases in 2019 – what does it mean?
Striving to understand the underlying challenges with Semi-Scheduled generators (re AER Issues Paper)
Prompted by the recent AER Issues Paper (submissions on that due today – Friday 24th July) but also aware that I’ve not yet published some broader thoughts in response to the ESB’s requests for input into their Discussion Paper on the Two Sided Market concept, I’ve posted some further thoughts. These have been informed by a longitudinal analysis of Aggregate ‘Raw Off-target’ values across all Semi-Scheduled plant.
Investigating the action on a trading interval boundary using the latest ez2view v7.4.5.665
Marcelle uses the latest release of ez2view (v7.4.5.665) to further investigate the impact of low dispatch prices in QLD on Saturday July 4 2020.
Recent trends in spot price distribution in QLD
In a sneak preview from the “Maximising Value in the NEM” webinar this Thursday, Marcelle looks at the changing distribution of spot prices in QLD.
AEMO releases its first* ‘Renewable Integration Study’ on 30th April 2020
An article today providing links to the ‘Renewable Integration Study’ which the AEMO released today, and also to the headline media coverage I have seen on my quick scan this morning.
Rooftop Solar PV systems did trip in SA on Friday 31st January 2020 in conjunction with the Heywood trip
Investing some time over the weekend with a some higher-speed data on output of rooftop solar PV systems across VIC and SA reveals some interesting observations about what happened on Friday 31st January 2020 in conjunction with the transmission damage and Heywood trip.
How Good is Solar Farming?
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.
