High volume reading aggregation

Use the high volume reading aggregation task for specific formula channel aggregation conditions, including:

  • Volumetric unit conversion (such as converting cubic feet of gas to therms). For more information Net Metering for High-Volumetric Gas Unit Conversion.

  • Single service point netting (such as calculating net generation for solar installations).

If the high volume reading aggregation task is required, configure it to run on a recurring schedule at least once per day. (See Task scheduler).

The formula ID used in this task must be exact.

ClosedVolumetric Unit Conversion Formula ID

$SP:N * Thermzone_X

The unit conversion named formula allows for flexibility in service point channel numbers.

Thermzone_X is a named constant representing a conversion factor. Conversion factors can change over time and more than one conversion factor may be created and used.

Single Service Point Netting Formula ID

Closed$sp:1 - $sp:2

Closed$sp:1 + $sp:2

Defines the sum of the interval values in a service point channel to those of another channel on the same service point.

Closed@pos( $sp:1 - $sp:2 )

The difference of the interval values in a service point channel from those of another channel on the same service point. Where any individual resulting interval is less than 0, the value must be set to 0. (This is possible if one of the channels contains negative values).

Closed@pos( $sp:1 + $sp:2 )

The sum of the interval values in a service point channel to those of another channel on the same service point. Where any individual resulting interval is less than 0, the value must be set to 0. (This is possible if one of the channels contains negative values).

Letters in formulas must be lower case. The formulas will not work if you use upper case (capital) letters. For more information about how to create a named formula, see Named formulas.

Scheduling considerations include:

  • Netting must occur before IEE runs the reading daily summary, selects like-days, and determines demand response event participation.

  • Netting must complete before IEE processes AMI billing export requests.

  • AMI billing export requests must complete in time for utilities to meet their daily billing schedule requirements (such as sending the bills before noon on a typical operations day).

Use the following procedure to configure a task template:

  1. Go to System Operations > Task Management > Task Templates.

  2. Use the dropdown menu to select the Task Type and Task Template. (Click Add to create a new task template. For more information, see Adding task templates.)

  3. Configure the Task specific parameters. These parameters are defined after step 5 of this procedure.

  4. Configure the Common task template parameters. For more information, see Task template parameters.

  5. Click Save.

Task specific parameters:

ClosedAggregation Type

Determines which formulas the High Volume Reading Aggregation task template runs. When you select an aggregation type from the dropdown menu, the template refreshes to display the other required parameters for the aggregation. For example, the Volumetric Unit Conversion aggregation requires a formula ID. The Net Meter Channel aggregation requires a service point ID and a start date.

ClosedFormula ID

Enter the named formula ID of the formula to use for this task.

ClosedService Point ID

Defines the unique identifier of a service point. Enter the exact service point ID.

ClosedStart Date

Defines the date on which IEE will start performing the netting calculations for the service point channels identified in the formula.
