Cancellation - Reclassification of the loss of Wagga 132kV B bus, the No2 and the No3 330/132kV transformers in NSW region.

AEMO ELECTRICITY MARKET NOTICE

Cancellation - Reclassification of the loss of Wagga 132 kV B bus, the No 2 and the No 3 330/132 kV transformers in NSW region - 14/06/2016.

Refer to Electricity Market Notice 53874 and 53888

Based on advice from the asset owner the circumstances that existed in relation to the tripping of the Wagga substation 132 kV B bus, the No2 and the No3 330/132 kV transformers have now been addressed

Therefore AEMO no longer considers the simultaneous trip of the Wagga substation 132 kV B bus, the No2 and the No3 330/132 kV transformers to be a credible contingency event from 1055 hrs 14/06/2016 .

Update - Reclassification of a Non-Credible Contingency Event in TAS Region

AEMO ELECTRICITY MARKET NOTICE

Update - Reclassification of a Non-Credible Contingency Event in TAS Region:
Trip of any Tasmanian Transmission Line and Basslink Interconnector for Basslink flow in the direction of Victoria to Tasmania

Refer to MN 47360 issued 19/12/2014 and MN 47855 issued 23/01/2015.

Advice provided to AEMO indicates that Basslink is unlikely to trip for 220 kV transmission faults close to George Town. As the George Town to Tamar Valley power station 220 kV lines are very short it is unlikely that Basslink will trip for a fault on these lines.

Based on this advice AEMO has reclassified the loss of any transmission line in Tasmania and Basslink Interconnector to be a credible contingency event for Basslink flow in the direction of Victoria to Tasmania only, except for faults on either of the two George Town to Pacific Aluminium 220 kV transmission lines or the George Town to Tamar Valley power station 220 kV transmission line, from 1151 hrs 13/06/2016 until further notice.

Reclassification of the loss of Wagga 132kV B bus, No2 and No3 transformer as a credible event 11 June 2016

AEMO ELECTRICITY MARKET NOTICE

Refer AEMO ELECTRICITY MARKET NOTICE 53874

At 0950 hrs on 11/06/16, the Wagga substation 132kV B bus, the No2 and the No3 330/132kV transformers tripped.

The cause of this non credible contingency event is not known at this stage.
AEMO is not satisfied that this non credible event is unlikely to re-occur.
AEMO therefore classifies this event as being a credible contingency event.

The No3 330/132kV transformer and the bus were placed on load from 1430hrs, the No2 330/132kV transformer remains de-energised.
