Energy economist says preliminary report makes clear South Australian event was ‘a transmission failure, not a generation failure’
The Australian Energy Market Operator has pointed to South Australia’s extreme weather last week as the prime cause of “multiple transmission system faults” resulting in a statewide blackout.
In a preliminary report the regulator cites severe weather as the factor triggering the transmission system failures “including, in the space of 12 seconds, the loss of three major 275kV transmission lines north of Adelaide.”
