Update to South Australian system black restoration.
AEMO ELECTRICITY MARKET NOTICE.
POWER SYSTEM EVENT
At 1618 hrs Wednesday, 28 September the SA power system separated from the NEM and became black. A very large lightning storm was traveling across the state at the time. Refer MN# 54994
At 0520 hrs the restoration is proceeding with approx. 900 MW restored in the South Australian region - load will continue to be restored and further updates will be given when information becomes available.
Due to potential damage in the north of the state, restoration in this part of the network could be delayed.
