Billing Report Requirements
A cost allocation rate schedule must be assigned to a group such that when the
CostAllocate method of a Group or Meter object is called then the billing report and rate
schedule can be located by searching up the tree from the group or meter. If either the
billing report or the cost allocation rate schedule cannot be found then the CostAllocate
method will return a value of zero.
Cost Allocation Example
This example shows how to set up a billing report and cost allocation rate schedule to
perform cost allocation by using a blended kWh charge.
1. Create a billing report to calculate the cost allocation rate.
Add a runtime parameter called ‘Cost Allocation Rate’. This would normally calculate
the total site cost and divide by the kWh consumed to arrive at a blended kWh rate.
This example includes a fixed monthly charge that is pro-rated based on the report
date range.
2. Add a global variable named TotalRealEnergyNet.
