On Thursday 10th October 2024, we published ‘What happened with System Load in VIC on Friday 27th and Saturday 28th September 2024?’ and, in doing so, listed some times when rooftop PV was disconnected (or consideration was given to the same). In this article (following some detail from a reader) we classify these events in three categories.
Inspired (or provoked) by Paul’s earlier article noting ‘NEM-wide demand has been quite low through summer 2023-24 (at least to date)’, guest author Allan O’Neil takes a look at how aggregate consumption stacks up for this summer, compared to prior.
Clutch’s Mitch Baker has shared his initial thoughts and questions that jumped out to him from reading the AEMO’s 2024 draft ISP.
A quick record of a new ‘lowest ever’ point for Market Demand in NSW on Sunday 8th October 2023
A short initial article to note that curtailment of distributed PV is underway in South Australia under processes previously established by the AEMO.
Hot on the heels of a new low point for Operational Demand in South Australia on the weekend, this evening AEMO warns of an ‘elevated risk of contingent disconnection of Distributed PV’ tomorrow (Wed 19th Oct 2022).
This article – Part A of a 2 part series – reviews how rooftop PV output varied and considers its influence on Queensland demand on the 1st and 2nd of February, 2022.
Ron Brakels of SolarQuotes examines recent changes that will put the CER in charge of accreditation, which he explains is aimed at “kicking crap solar installers out of the industry”.
Just last Friday the AEMO notified stakeholders more broadly about their new Market Notice Framework about ‘Minimum System Load’ and/or ‘Distributed Photovoltaics (DPV) Contingency’ … prior to Sunday’s new lowest point for minimum demand in South Australia!
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).
After reviewing a monthly electricity bill for 2021, Murray Hogarth of Wattwatchers discusses issues arising from ‘smart meters’ and how a lack of accurate data for electricity consumption may be misleading many consumers.
A month on from the prior low point seen for Scheduled Demand (and Operational Demand) across Queensland in the middle of the day, the low point mark is driven lower still on Sunday 27th September 2020.
Guest author, Andrew Wilson, reviews the performance of his home solar + battery system at the one year mark after installation.
Some quick notes today, to document high-level data (to be explored later) relating to some significantly depressed solar harvest data today due to the widespread cloud/wind event.
SwitchDin’s Joseph Kassouf examines the real-world challenges of coordinating control of rooftop solar inverters.
Tom Geiser, Senior Market Manager at Neoen, discusses the merits of proportional, relative control on the issue of small solar curtailment.
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.
Following yesterday’s dust storms, today’s rain (and hail) also sweep through NSW to dampen production from solar farms – small and large.
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.
Recently there have been a number of media reports of energy industry people talking about too much solar. One of our guest authors takes a look.
