Guest author, Allan O’Neil, takes the release of the GSD2022 as an opportunity to take a look at the past 10 years of performance of the four-unit Liddell Power Station (one unit closed in 2022 and three to close soon in 2023), contrasting against two other black coal-fired stations.
Prompted by a few media questions (on a day when all 4 units were offline together for about 3 hours), have taken a quick look at the status of the four units on the Callide Power Station site.
As a first article on WattClarity following Origin’s ‘Notice of Closure’ announcement about the future of Eraring Power Station, here’s some statistical data (from the upcoming GSD2021) to help with the broader conversation.
A quick look at the coal units that are currently offline today in the QLD region, in the lead-up to the tight supply-demand balance.
Another interim build of ez2view gives me an excuse to have another look at changes in bidding patterns at selected Wind, Solar and Coal units.
On Wednesday 13th October 2021, TransGrid released it’s ‘Energy Vision’, containing modelled results for 6 different scenarios out till 2050.
Prompted by reports elsewhere of solar PV production eclipsing coal-fired production on Sunday for a period of time, I had a quick look (including at aggregate bid volumes).
The volatility that has been with us for weeks now (particularly QLD and NSW), and the dramas unfolding at Callide power station, prompted me to have a broader look at the availability of black coal plant across QLD and NSW, and compare this to prior Q2 periods.
Saw an update from the AER this evening pertaining to Liddell unit 3, and had a quick look with the power of the Generator Statistical Digest 2020.
A report released this week by Green Energy Markets and the IEEFA exploring the prospect of accelerated coal closures, has itself caused some ripples…
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.
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.
David Leitch and Ben Willacy of ITK Services provide analysis of the NSW Government’s recently announced renewable energy plan.
A short article providing access to the much-talked-about report.
Questions from several readers prompted this quick look at the long-term trend of coal generation.
Some excerpts from the Generator Report Card to sample some of the analysis we performed to assess various aspects of the ‘dependability’ of coal-fired power stations in the NEM. In this post we highlight availability (or, more precisely, the level of unavailability) as an aggregated monthly volumetric measure trended over 17 years.
The framework we used to analyse the extent to which coal-fired power is “dependable” in the Generator Report Card, and the extent to which it’s been changing.
Guest author, Tristan Edis, takes a look at the changing pattern of generation by fuel type in 2018
