The Australian Energy Market Operator (AEMO) advises that on Sunday, 20 December 2015 at approximately 15:03 Australian Eastern Daylight Time (AEDT), a fault occurred on the Basslink Interconnector running between Victoria and Tasmania, separating Tasmania from the National Electricity Market. As at 11:00 AEDT on Tuesday, 22 December 2015, the Basslink Interconnector remains out of service.
There are no forecast electricity generation supply shortfalls in Victoria or Tasmania over the Christmas and New Year period as a result of the Basslink Interconnector outage.
Electricity supply surpluses are currently forecast in both states over the next 14 days, even with Basslink out of service.
Asset owner Basslink is investigating the cause of the outage, and will advise on a return to service date.
At the time of the incident, approximately 254 megawatts from four large industrial customers within Tasmania were disconnected under the Frequency Control Special Protection Scheme, which protects the broader Tasmanian network. This load was restored within 30 minutes.
This fault has not resulted in any electricity supply disruptions to Victorian or Tasmanian residential or commercial customers to date.
AEMO will continue to monitor forecast electricity supply and demand in both states over the next 14 days and beyond, and is working with Basslink and the Victorian and Tasmanian state governments to ensure the appropriate arrangements are in place while the fault is being resolved.
