Case Study (part 1) of Aggregate Scheduled Target on Friday 8th September 2023
The first part of a Case Study looking at a large 5-minute ramp in ‘Aggregate Scheduled Target’ in the middle of the day (an unusual time) on Friday 8th September 2023
Aggregate Scheduled Target
An ESOO snippet – how effective are different technologies at enhancing reliability?
In his second article about the 2023 ESOO, guest author Allan O’Neil takes a look at what the AEMO has published with respect to various options for firming capacity to increase the reliability of aggregate supply to below the two thresholds (the Reliability Standard and the Interim Reliability Standard)
Case Study of high AggSchedTarget on Thu 30th Jan 2020 and Fri 31st Jan 2020 (part 1!)
In this article we delve in deeper on Thu 30th Jan and Fri 31st Jan 2020 … two days that saw extreme levels of ‘Aggregate Scheduled Target’ (i.e. AggSchedTarget – a requirement for firming capacity). A timely review, given two developments arriving tomorrow (on Thursday 31st August 2023).
Digging further into ‘Aggregate Scheduled Target’, to understand what Dispatchable Capacity is actually required
In conjunction with the analysis done to complete GenInsights Quarterly Update for Q1 2023 (released today), here’s 14 years of daily data of ‘Aggregate Scheduled Target’ that might help to illustrate the aggregate requirement for fully dispatchable capacity of some type as the closure of coal accelerates into the future.
We’re not building enough replacement dispatchable capacity
With completion of GenInsights Quarterly Update for Q1 2023 approaching, and following some conversations recently (and probably this week at EUAA Conference) here are two charts looking backwards just at fully dispatchable plant that highlight one of the ways in which ‘the level of risk in the NEM is escalating’.
