A time-of-use (TOU) group is a set of TOU maps that define how usage is divided into different TOU periods for different days of the week and seasons of the year. A TOU group can have a work calendar associated with it to define holidays and other special days that may have different TOU periods than regular days. According to the Oracle Utilities Meter Solution Cloud Service Business User Guide, to configure a TOU group for“on peak”, “off peak”, and “shoulder” periods and have holiday consumption categorized as “off peak” regardless of the day on which it falls, the correct steps are:

• Add the work calendar to the TOU map template and set the Holiday TOU as “off peak”. This will ensure that any day marked as a holiday in the work calendar will have its usage assigned to the “off peak” period.
• Create a TOU map for each season using the TOU map template and define the start and end times for each TOU period (“on peak”, “off peak”, and “shoulder”) for each day of the week.
• Create a TOU group and add the TOU maps for each season to it.

To calculate the power factor for a bill, you can use the Vector and Quantity Math rule to derive the power factor from the kWh and kVArh channels. The Vector and Quantity Math rule is a usage calculation rule that facilitates the configuration of complex vector calculations. It is based on a series of underlying services with vectors configured as input to the calculations. The power factor is a ratio of real power (kWh) to apparent power (kVAh) that indicates how efficiently a device uses electricity. The power factor can be derived from the kWh and kVArh channels by using a mathematical formula.

You do not need to use a virtual meter to perform the calculations, which is a configuration that defines how measurements from multiple devices or service points are aggregated or disaggregated. A virtual meter is not used to calculate derived values from measurements, but to create new measurements from existing ones.

You do not need to use a measuring component derivation algorithm to calculate the power factor, which is a custom logic that can be developed by using Groovy scripting language or Java programming language. A measuring component derivation algorithm is not used to calculate derived values from measurements, but to create new measuring components from existing ones.

It is not true that power factor can only come from the meter and cannot be calculated. Power factor can be calculated from other measurement channels, such as kWh and kVArh, by using usage calculation rules.
