On Friday morning 15th November 2024 we see the return to service of both YWPS1 and LYA2 – coincident with the cancellation of Victorian directions for System Strength.
We (and others) wondered, why the direction (especially for 4 units) to replace the System Strength from the ‘missing’ coal units?
On Thursday morning 14th November 2024, the AEMO has directed 4 different units to operate, to cover a potential system strength shortfall in the Victorian region.
It’s not (yet?) a frequent occurrence, so worth noting that AEMO has directed 2 units at Murray to synchronise and operate as a synchronous condenser from 08:00 (NEM time) on Thursday 24th October 2024 (to protect against low System Strength)
Thursday morning 23rd May 2024 saw a media News Conference and announcement that Eraring closure will be delayed until August 2027 … or possibly as far out as August 2029.
AEMO points to the TransGrid document from Wed 14th Feb 2024 ‘NSW Synchronous Generation – interim advice for System Normal requirement’.
A quick note about a forecast by AEMO of shortfall in system strength in NSW region for Tuesday 14th November 2023.
On Wednesday 6th September many Semi-Scheduled (wind and solar) units in northern QLD were ‘constrained down’ for System Strength reasons. We take a first look as part 1 of a Case Study (more parts *may* follow).
Kate Summers gave the keynote address for the “System and market design for a high renewables future” session at the CEC’s Clean Energy Summit earlier this week. This article contains the full text of her speech.
Three other reports released by AEMO on 1st December 2022 will also make for interesting reading.
Marcelle explores the little-understood concept in NEM dispatch of the tie-break principle, using the new ‘Constraint Dashboard’ widget in ez2view.
From 10:00 today (Friday 10th September 2021), ElectraNet’s new synchronous condensers (which have been under testing) will be deliver a boost to Semi-Scheduled units in South Australia.
Saturday evening 25th July 2021 saw the instantaneous production from wind farms across the NEM surge past 6,000MW for the first time and set a new ‘all-time’ record that’s substantially higher than the previous record (set only a few days beforehand).
A look this morning at the new record (set yesterday – Tuesday 20th July) for NEM-wide wind production.
We’ve started exploring the constraint data from the QLD region for back on Tuesday 25th May 2021 (with the Callide C4 catastrophe) and here’s some initial information.
Part 5 in an expanding series, looking at what happened in QLD on Tuesday 25th May 2021 – this one looking at system frequency.
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.
A different type of market notice today (speaking of potential curtailment of embedded generation in South Australia) points to the future … accelerated by Heywood repairs in this instance.
Guest author Allan O’Neil puts together an in-depth explainer about system strength and looks at the current approach to system strength management in South Australia, its impacts and the imminent installation of synchronous condensers on the SA grid.
In this (lengthy) article today, Paul McArdle uses the newly released GSD2020 to take a look at the units that were most frequently impacted by constraints during calendar 2020 – with a view to how this has changed from 2011 to 2020.
