Explanation / Answer

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
