Following several different warnings of high temperatures forecast for the lead-in to Tuesday 26th January 2021 (whatever you want to call that day) I’ve taken a quick look at what it’s currently forecast to mean for the NEM…Read More
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).
NEM Local Temperature alert for Dalby (QLD) for Sat 16th Jan 2021 … an opportunity to check the draft GSD2020
Today (Wed 13th Jan 2021) a high temperature alert published by AEMO for the Dalby area in southern QLD prompted a quick look at what the GSD2020 shows, in terms of high-temperature limitations of plant around the Dalby area.
A pretty rare event in the NEM, when two units trip simultaneously … so a short article on WattClarity as a result.
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.
In the same week that the Energy Security Board publishes it’s ‘The Health of the NEM’ reports, looking from a top-down systems perspective, we crank the handle to produce the ‘Generator Statistical Digest 2020’ as a bottom-up 10-year review of the performance of all Scheduled, Semi-Scheduled and some Non-Scheduled generators and scheduled loads across the NEM that operated through some part of 2020.
Using an in-development (but soon to be released) widget in ez2view we take a look at forecast availability for coal units in NSW, VIC and QLD for the critical, and normally volatile, Q1 period 2021.
Short note about what might be a new record low point for electricity demand in Victoria on Christmas Day 2020.
As we wind down for Christmas, recapping some developments (in Nov and Dec 2020) about high temperature limitations on generation technology across the NEM.
An unfortunately timed significant slump in output across all Wind and Large Solar plant in NSW was another of the factors contributing to the price volatility seen in NSW last week.
Following a week where several days saw price volatility in NSW (with this being so extreme that Reserve Trader was triggered on Thursday 17th December) we’ve taken a look at the comparative performance of coal units across the NEM (and particularly in NSW) compared to prior years.
The publication by AGL Energy of the short note about the transformer incident (and injured worker) at Liddell unit 3 yesterday prompted me to have a quick look, following on from the volatility this week.
Following up to AEMO’s recent Intermittent Generator forum, Marcelle looks at the challenges for wind and solar farms in providing consistently good plant availability information to AEMO and the value of transparency of this data.
Third day in a row we see volatility in NSW (and QLD) … and this afternoon AEMO contracts, and then dispatches, Reserve Trader in NSW
David Leitch & Ben Willacy of ITK Services provide an overview of the wind and solar assets in the NEM that are currently up for sale
Second day in a row the price spikes in the NSW region … higher and longer than yesterday. Low aggregate production from Wind and Large Solar across NSW today was clearly one other factor that contributed.
A quick look at a spike in NSW price this afternoon above $3,000/MWh due to a number of different factors … including a trip of unit 3 at Eraring coal-fired power station.
This is the fourth of a short series of video snippets extracted from the 17th September 2020 presentation by Marcelle Gannon and Jonathon Dyson for the Clean Energy Council entitled ‘Maximising Profitability in the NEM’ for Wind Farms.

On 25th November, guest author Allan O’Neil examined the ‘X5 Constraint’. Two weeks of operation have passed, so now Allan reviews some of what’s happened.
