Understanding different Factor rate types

Flat rates

A single fixed charge applies uniformly, independent of time of day, day of week, or season. The rate does not vary with usage patterns and may be expressed as a charge per unit of consumption (kWh), per demand (kVA), per day, or as a fixed monthly fee.


Temporal rates

Variable rates apply depending on the time of day, day of week, or season etc. Different unit rates may be set for peak, shoulder, and off-peak periods, summer, winter and can apply to consumption (kWh), demand (kVA), daily charges, or other billing determinants. Temporal rates are explicitly linked to a Partition.
