Yesterday evening I noticed this tweet from TasNetworks noting about customers off supply because of severe weather in the south-east of the state:
Overnight I see a series of Market Notices issued by AEMO speaking about various transmission lines tripping … the cause of which is not stated (but I am guessing might have something to do with this severe weather):

MN 96967 (refers to 96964) Sun 12th June 09:04:53 |
This one says: ‘At 2229 hrs the Palmerston – St Marys tee Avoca 110 kV Line tripped and Mussleroe Wind Farm reduced output by approximately 135 MW. 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 has therefore reclassified this event as a credible contingency event until further notice. Region: Tas |
Sounds like a busy period for the TasNetworks team.
