Comparison of Reliability Measures
The situation now is:
- C1 = 990 MW with FOR1 = 0.0003 and ...
- C2 = 110 MW with FOR2 = 0
- \ Installed Capacity = C1 + C2 = 1,100 MW.
Then since neither the (peak) load nor the installed capacity have changed, the reserve margin is still 10%.
890 MW of load is not served iff unit #1 fails so the LOLP is still 0.0003 (i.e., the LOLP now equals FOR1 and FOR1 = 0.0003).
