Some key events in the NEM that carried long-term implications
As December 2023 draws to a close, we take another look at return-to-service expectations for Callide C3 (a couple more weeks) and then Callide C4 (a few more months). References Nick Evans’ interesting articles.
A quick update today, following news yesterday from CS Energy about a 17-day delay to the expected return to service of Callide C3, following repairs to the collapsed cooling tower.
In our third guest authored post this week, Blake Ashton from SA Power Networks talks about the SA islanding event that occurred just over twelve months ago – how SAPN managed solar curtailment, and how their new ‘flexible exports’ option can address future challenges.
AER announced today (and CS Energy confirmed) that a fine had been issued, and paid, for ‘allegedly operating a generating system without regulatory approval’ – with respect to the Callide C units on 24th May 2021 (i.e. the day before the explosion – but I believe unrelated to the explosion).
A quick article, following a social media update by CS Energy on the repair process for the cooling towers at Callide C.
A quick note on WattClarity to tie in an update (earlier this month) from CS Energy on the rebuild of the cooling tower for Callide C3 and C4.
Also today, we saw an AER notice about fines paid by Stanwell Corporation related to what happened after Callide C4 exploded on 25th May 2021
More updates recently about the Callide C power station. Looks like we’ll be waiting a while longer for the (delayed again) return to service…
AFR and the Australian (and elsewhere?) there are reports of the co-owner of Callide C (with CS Energy) being placed in voluntary administration.
A short article today noting the additional delays in return-to-service expectations for both Callide C3 and C4.
News of the arrival of another high cost replacement component (generator stator) at Callide C4 prompts me to have an updated look … with a new feature in ez2view.
Yesterday (Wed 28th Dec) CS Energy informed the market of further delays in RTS for Callide C3 and C4 – today we take a quick look.
Two media articles (in the Guardian and the Australian) prompt a quick article, utilising an in-development copy of the up-coming GSD2022.
A quick note to echo the news from CS Energy that the replacement generator transformer is onsite.
In light of recent events, Dan Lee does some digging to find historical incidences of islandings and transmission tower failures.
Today (Thu 15th Dec 2022) the AER released its ‘June 2022: Market events investigation report’, which might be widely read.
Striving to catch up on a couple weeks away, today I’ve tried to piece together the current state of deliberations about the potential (and rushed) implementation of caps on domestic gas and coal prices feeding into the NEM.
Another headline report released in the past couple weeks was the ACCC’s 8th update of its ‘Inquiry into the National Electricity Market’
Close to $31.5M of revenue was generated in the FCAS markets in SA over the seven days that the region was frequency separated from the rest of the NEM. This follow-on from Allan O’Neil’s earlier article investigates this final figure.
A successful return to service for the Waddamana to Palmerston 220 kV lines following damage sustained during landslides on 14 October 2022.
