Give:
Go to the load duration curve and find the area
Total Area=Area of Triangle+ Area of Rectangle => 623000 MW hrs/yr
So meet the load for 100 GW Load, the three generating units should run for 623000 MW hrs/yr.
For the following
Solve the above equation using the CT($/yr) value from first graph
CT= 7516
NGCC= 8333
Coal= 9090
Divide the same with 623000 MW Hr/Yr
CT= 37 GW
NGCC= 31.5 GW
Coal= 31.5 GW
