Advanced metering is a prerequisite for most demand response because it

  • A.reduces the losses in the distribution network
  • B.improves the accuracy of the energy measurement
  • C.allows the consumer to generate energy as well as consume it
  • D.records consumption by interval rather than as a single total

Answer: D

Correct answer: records consumption by interval rather than as a single total

A conventional meter gives one cumulative figure, from which the time of consumption cannot be recovered, so no time-varying tariff can be billed and no response can be verified. Interval metering is what makes both possible, which is why metering rollouts precede demand response programmes.
