2021 – 25th May – Callide C4 Explosion, Fire and Outage
A collection of articles that began on Tuesday 25th May 2021, when Callide C4 unit exploded, which:
1) Led to loss of supply from sister units Callide C3, and B2 and B1 – but also others close
2) And also blackouts for a sizeable amount of Queensland due to under-frequency load shedding
3) And a very long repair process
4) Hence some concerns about the supply-demand balance, and prices
5) And an insolvency of one of the JV owners
6) There also was a lengthy process to report on the original cause of the explosion.
In this category we collate an expanding range of articles related to one or more of the above.
