(i.e. we need to determine online and off-line non-spin obligation) Quick-starts that are offered into balancing should be shown online and available in the Resource Plan in order for SPD to dispatch them. For each QSE, the AS obligations were subtracted from the QSEs’ Spinning, and any deployments were added back in. After doing this exercise, 10 out of 46 active QSEs (includes sub QSEs) came up negative for IE 07:15 This totaled nearly 556 MW Summary
