After a lull in the winds this week, wind power is set to pick up from rock bottom as a rare easterly wind surge impacts Qld, NSW and SA.
Wind power has been slack this week across the National Electricity Market (NEM) in response to a stubborn high-pressure system which has parked itself over the Bight.

This high will continue to sit over the Bight and Tas, until it finally moves east into the Tasman Sea on Monday, July 8.
The image below shows that we saw low wind power in the order of 30 to 60 GWh/day in response to this high earlier this week, but wind has picked up slightly to 100 GWh/day on Thursday, July 4.
