Question
C. Suppose that a certain fraction of the power produced by a 350 MW coal plant is offset by wind power. Assume that when the coal plant runs at its constant rated power it has an efficiency of 37%, but that when it needs to be ramped up and down to compensate for the wind power variations its efficiency is reduced by according to e=0.37-0.00001p², where p is the amount of wind power. Find the percentage increase in emissions that results when 90 MW of the 500 MW is generated by wind power instead of coal. What will be the maximum power of the plant?
