Utility measurement using rate of consumption per unit weighting for successive accounting periods

摘要

The per unit price from which the charge for consumption is derived is not necessarily constant over a period for which the consumption is measured. To derive an appropriate charge in such circumstances, a set of weightings defined for successive accounting periods and the value of measured or recorded (metered) consumption during a finite metered period are used to determine a rate of consumption per unit of weighting. The determination is made by dividing the value of metered consumption by the sum of the weightings for those accounting periods encompassed by the metered period.
