Other WMS activity • PRR601, 15 Minute Ramping for BES and Base Power Schedule • Ramping for the entire 15-minute interval will allow more BES to be deployed and may tend to reduce Regulation Service (RGS) deployment • Significant time can be saved by changing the start and end times of the ramp rate from a decimal value (7.5) to an integer value (such as 7). There are equally significant savings if the before and after values are identical (such as 7/7). • ERCOT to file Urgent PRR using 7/7 (PRR 803)
