Create load report

Create a simple electric distribution report that displays the count of customers and total load per phase by tracing downstream from a given point.

Use case

You can use a load report to display the customers per phase as well as the load per phase based on a chosen starting point in a utility network. Load reports are used for electric load restoration and balancing.

How to use the sample

Select phases to be included in the report. Press the "Run Report" button to initiate a downstream trace on the network and create a load report. Pressing "Run Report" again will generate a new load report. Deselect all phases and press the "Reset" button to clear the report.

How it works

  1. Create a ServiceGeodatabase with a feature service URL.
  2. Create and load a UtilityNetwork using the service geodatabase, then get an asset type, tier, network attributes, and category by their names.
  3. Create a UtilityElement from the asset type to use as the starting location for the trace.
  4. Create a UtilityTraceConfiguration from the utility tier.
  5. Create a UtilityCategoryComparison where "ServicePoint" category exists.
  6. Reset the functions property of the trace configuration with a new UtilityTraceFunction adding a "Service Load" network attribute where this category comparison applies. This will limit the function results.
  7. Set outputCondition with the category comparison to limit the element results.
  8. Get a base condition from the utility tier's default trace configuration.
  9. Create UtilityTraceParameters passing in downstream utility trace type and the default starting location. Set its traceConfiguration property with the trace configuration above.
  10. Populate a list of phases using the network attribute's codedValues property.
  11. When the "Run Report" button is tapped, run a trace for every checked CodedValue in the phases list. Do this by creating a UtilityTraceOrCondition with the base condition and a UtilityNetworkAttributeComparison where the "Phases Current" network attribute does not include the coded value.
  12. Display the count of "Total Customers" using the elements property of the result, and the result of "Total Load" using the first and only output in functionOutputs property.

About the data

The Naperville electrical network feature service, hosted on ArcGIS Online (authentication required: this is handled within the sample code), contains a utility network used to run the subnetwork-based trace shown in this sample.

Additional information

Using utility network on ArcGIS Enterprise 10.8 requires an ArcGIS Enterprise member account licensed with the Utility Network user type extension. Please refer to the utility network services documentation.
