53: Callide C Blackout


Listen Later

In 2021 the Callide C Power Station experienced a unit failure that tore the turbine-generator apart, resulted in hundreds of thousands of premises losing power, and cost hundreds of millions to repair. We look at how design errors and ultimately a lack of information led to the incident escalating out of control, when it could have been recovered.
With John Chidgey.
