Bruce Miller talks about why system strength is badly misunderstood. Through analogies using bridges, seeing eye dogs, and bumpy roads, he argues the industry's fixation on fault level and inertia misses the real engineering challenges of the transition — and risks costly, counterproductive fixes.
Inertia levels, measured in megawatt-seconds (MWs), dropped towards the targeted secure operating level and the minimum threshold level on 12 November, 2024.
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...
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.
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.
Following the low levels of demand over the weekend (Sat 16th and Sun 17th Sept 2023) here's a few quick notes.
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...
Three other reports released by AEMO on 1st December 2022 will also make for interesting reading.
On Sunday 6th November 2022 the NEMwide demand dropped below previous 'lowest point' records.
