Mapping to Time of Use (TOU) Periods

Many customers choose not to price their interval data using interval prices. Customers may choose for their interval data to be mapped into time of use (TOU) periods. This option for interval data might be preferred because:

• Typically it involves fixed prices for the use periods
• It is more manageable than direct billing
• It is easier for a customer to forecast and budget

A TOU map's purpose is to define the TOU codes for a collection of time period definitions (i.e. given dates and times). The TOU Map has a TOU Map Type, which defines the interval size between TOU map data rows.

Time of use periods can (and often do) change during the year.

All the possible TOU codes for a given map are grouped together in a TOU group. Refer to Grouping of TOU Codes for TOU Mapping for more information.
