In Oracle Utilities Customer to Meter, the requirement to measure bothimport(energy received from the grid) andexport(energy sent to the grid from solar generation) using a single scalar device with separate registers requires careful configuration ofmeasuring component types. The Oracle Utilities Customer to Meter Configuration Guide specifies that the correct solution is tocreate two new measuring component types, one for subtractive import and the other for consumptive export, to enable the creation of two measuring components that will be linked to one scalar device.

Ameasuring componentis a point that captures and stores measurement data, and its type defines how the data is processed (e.g., subtractive or consumptive). In this scenario:

Thesubtractive import measuring component typeprocesses import readings by subtracting the previous reading from the current reading to calculate consumption (e.g., grid energy used).

Theconsumptive export measuring component typeprocesses export readings as direct measurements of energy generated and sent to the grid.

By creating two distinct measuring component types, the system can link two measuring components to a single scalar device (the meter), each corresponding to a separate register (one for import, one for export). This configuration ensures accurate tracking of both import and export energy in kWh, with the appropriate calculation logic applied.

The Oracle Utilities Customer to Meter Implementation Guide highlights that this approach is ideal for net metering scenarios, as it allows utilities to bill customers for net consumption (import minus export) while accurately reporting exported energy for credits or grid management.

The other options are incorrect:

Option A: Create one new measuring component type for creating a new measuring component that will be linked to two different scalar devices.This is incorrect, as the requirement specifies a single scalar device with separate registers, not two devices.

Option B: Create two service points, one for subtractive import measuring component and the other for consumptive export, that will be linked to one scalar device.This is incorrect, as a single service point is sufficient, and multiple service points would unnecessarily complicate the configuration.

Option D: Create one new measuring component type for creating two measuring components, one measuring component for subtractive import and the other for consumptive export, that will be linked to one scalar device.This is incorrect, as a single measuring component type cannot support both subtractive and consumptive calculations simultaneously; separate types are needed.

Practical Example:A customer with solar panels has a scalar meter with two registers: one for import (subtractive) and one for export (consumptive). The utility configures two measuring component types: “Import kWh” (subtractive) and “Export kWh” (consumptive). Two measuring components are created and linked to the meter, capturing import readings (e.g., 500 kWh – 400 kWh = 100 kWh used) and export readings (e.g., 200 kWh generated). The system uses these measurements for net metering, billing the customer for net consumption and crediting export.

The Oracle Utilities Customer to Meter User Guide notes that this configuration supports renewable energy integration, enabling utilities to manage distributed generation while maintaining billing accuracy.
