Wind, solar pick up slack as South Australia cut off from main grid

November 21, 2022

Renew Economy:

The South Australia grid has been reconnected – or re-synchronised – with the country’s main grid after a week of “isolation”, during which time wind and solar still managed to deliver nearly two thirds of its electricity needs.

The Australian Energy Market Operator says South Australia was re-synchronised with the National Electricity Market at 1803 (AEST) on Saturday after the main 275kV line near Tailem Bend was returned to service.

That occurred a week and a couple of hours after wild storms blew down a transmission tower and caused multiple circuits to trip, and causing the state to be “islanded” from the main grid.

The loss of synchronisation with the rest of the NEM meant that the South Australia grid was effectively “isolated” for just over a week – although it has a smaller high voltage connection through MurrayLink – forcing AEMO to introduce emergency measures to maintain grid stability.
