Aug. 20 — The settlement states that, on July 30, August 5, August 11, and August 12, 2015, fifteen Luminant quick start units at the Permian Basin, Morgan Creek, and DeCordova generation sites simultaneously telemetered a down ramp rate of zero when operating near maximum capacity.

The settlement states that because of the zero down ramp rate, during this time, ERCOT’s Security-Constrained Economic Dispatch (SCED) was prevented from dispatching the units down.
