A load of 200 MW is shifted from the peak to the off-peak hours. The energy the utility sells

  • A.falls by the amount shifted
  • B.rises by the amount shifted
  • C.falls by the amount of the losses avoided at the peak
  • D.is unchanged, only its timing having moved

Answer: D

Shifting moves consumption in time and removes none of it, which is why it helps the utility's capacity position without hurting its revenue. In practice the off-peak losses are lower, so the generation required falls slightly.
