SPP extended its record for wind energy production to 17,595 MW on Thursday, the RTO announced the next day.

The record came at 8:23 p.m. CT, breaking the old mark of 17,109 MW set on Sept. 30. Given SPP’s 22,313 MW of installed wind capacity, that means 78.9% of the RTO’s capacity was in use at that time.

The wind gusts continued over the plains Friday, when SPP’s wind output reached 17,264 MW. Much of the region saw negative LMPs.
