Slide 12 of 33
Notes:
This is a duration curve of all the reliability events found in February, 2003. The simulation examined 336,000 hours over 500 simulations.
The 2.5 MW average curtailment from the previous chart comes from this set of observations.
Only about 0.17 percent of the hours examined in February, 2003 had a reliability problem. Demand could be met in over 99.8 percent of all hours.
A small percentage of the hours with unserved demand had problems of over 4000 MW.
Most of the problems indentified were 3000 MW or less
