Case Study of inertia supplied by source in the NSW grid on Tuesday 14th November 2023
With GenInsights Quarterly Update for 2023 Q4 completed, and some time till the end of 2024 Q1, we’ve looked back at Tuesday 14th November 2023 (when AEMO had concerns about low System Strength in NSW) and looked at the level of inertia actually seen in the grid. A useful Case Study to say ‘what would have happened without Eraring?’
Grid Inertia in the Victorian Region drops with the coincident tripping of 4 x Loy Yang A units
With a trip of four large synchronous units in Victoria (all supplying large amounts of inertia) it’s no surprise to see that inertia levels fell significantly this afternoon in Victoria.
Demand in Victoria drops to a new lowest point on Sunday 31st December 2023, and AEMO flags possible intervention (Part 1?)
First article today, recording a new ‘lowest ever’ point for demand in Victoria (Sun 31st Dec 2023), and possible intervention from AEMO has it looks to drop further, leading to possible grid instability.
About the low Operational Demand on Sat 16th Sept and Sun 17th Sept 2023
Following the low levels of demand over the weekend (Sat 16th and Sun 17th Sept 2023) here’s a few quick notes.
Current expectation for closure dates of Liddell and Eraring Power Stations
Drawing from GenInsights Quarterly Update for Q4 2022, and the next version of our ez2view software, we take a look at the *current* expectations for closure of Liddell Power Station (within weeks) and Eraring Power Station (in 2025). A segue into this week’s update to the ESOO, perhaps?
AEMO reports on (and webinar about) System Strength, Inertia and NSCAS
Three other reports released by AEMO on 1st December 2022 will also make for interesting reading.
New lowest point for NEMwide demand on Sunday 6th November 2022
On Sunday 6th November 2022 the NEMwide demand dropped below previous ‘lowest point’ records.
