The MSSC for your BA is 650 MW. Your reporting threshold is > 520 MW. (650 x 80%). What is the
percent of recovery for the following situation?
Loss of a 575 MW unit
Pre-disturbance Ace = 150 MW
Post-recovery Ace = 10 MW - ✔✔+150 + (-575) = -425
, -425 + (x) = 10, x= 435
435/425= 100%
The MSSC for your BA is 650 MW. Your reporting threshold is >/equal to 520 MW. (650 x 80%) What is
the percent of recovery for the following situation?
Loss of a 600 MW unit
Pre-disturbance Ace = 150 MW
Post-recovery Ace = -50MW - ✔✔+150 + (-600) = -450
-450 + (x) = -50, x= 400
400/450= 89%
