Assume the maximum amount of power a plant can generate is 10,000 MW. For half the year it generates 8,990 MW of power, for a quarter of the year it generates 8,600 MW of power, for 15% of the year it generates 5,000 MW, and for 5% of the year it generates 2,500 MW. For the remainder of the year, the plant is not operating. What is the capacity factor of the plant for the year?
