TOU values can be used for more than recording prices. Many contract-based values may also be recorded per TOU. For example, a contract for an interval billing customer may designate a hedge cover or a minimum demand value or a contract demand value. Although you may have interval quantity curves to define these values, that would be difficult to define and maintain. A more common scenario would be to define a TOU Map and to define these values for each TOU. A TOU Bill Factor could be used to define these values.
