The area under a load duration curve represents the

  • A.peak demand over the period
  • B.capacity required to meet the peak
  • C.cost of supplying the load
  • D.energy consumed over the period

Answer: D

Correct answer: energy consumed over the period

The load duration curve plots demand against the time for which it is equalled or exceeded, so the area under it is power multiplied by time - energy. Its height at the left gives the peak, which sets the capacity required, so the curve shows the two quantities that matter in one picture.
