Event Settlement Rule - Demand Based

This rule is used to calculate "Combined kW Drop" event settlement transactions that represent credits that will be applied to a customer's bill based on participation in an individual event. This rule averages values captured on "kW Drop" event settlement transactions and multiplies the result by a price. Prices can be defined in the rule configuration or can be derived by an algorithm. The average "kW Drop" value (captured as the Settlement Quantityon the "Combined kW Drop" event settlement transaction) is calculated from the "Max Drop" values from the "kW Drop" event settlement transactions that fall into the "top" percentage of values defined by the Demand Drop Percentage (%) parameter. See About Event Settlement Transactions for more information about the distinction between "kW Drop" and "Combined kW Drop" event settlement transactions.

Note: The base package does not include algorithms for deriving prices for use in event settlement calculations. Implementations must configure their own algorithms if they wish to derive prices.

Calculation Details

The Calculation Details section is used to define how the average "kW Drop" value is determined and the price used in the rule's calculations.

• UOM: The unit of measure used to define the average value to be created in the event settlement transaction.

• TOU: The time of use period used to define the average value to be created in the event settlement transaction.

• SQI: The service quantity identifier used to define the average value to be created in the event settlement transaction.

• Interval Size: The size of the average value to be created in the event settlement transaction represented as hours:minutes:seconds (HH:MI:SS).

• Line Description: A text string that describes the event settlement transaction. This can include the following variables:

  • %SQ = Quantity

  • %UP = Unit Price

• Price Source: The source of price data used by the rule. Options include:
  • Algorithm: A custom algorithm that derives the price.
  • Unit Price: A specific price to be used by the rule
• Price: The price that will be multiplied by Settlement Quantity on the "Combined kW Drop" event settlement transaction to determine the "Combined kW Drop" event settlement transaction's Settlement Amount.
• Demand Drop Percentage: The top percentage of "kW Drop" event settlement transactions that will be averaged. The rule uses this value to select the top n% of "Maximum Drop" values from the "kW Drop" event settlement transactions. For example, if there are 10 "kW Drop" event settlement transactions and this parameter is set to "70%", the rule would calculate the average for the top 7 values.

SQ Rounding Details

The SQ Rounding Details section defines the manner in which service quantities are rounded. These parameters allow configuration of the Rounding Method by which quantities are rounded (Up, Down, or Nearest) and the number of Decimal Positions retained after rounding.
