Bill Allocation to Specific End-Uses
Results from the process are returned for use in calculating energy bill.
Once the monthly electricity bill has been returned by the TAP web service, the monthly average (not marginal) electricity bills by end-use are estimated by allocating the whole-house monthly bill according to the relative monthly energy consumption for each end-use using Equation 37.
monthlyBillhouse = monthly bill returned by TAP service
monthlyFactorendues = monthly allocation factor derived from CEC loadshapes
annualEnergyendues = calculated energy for endues
monthlyEnergyhouse = monthly energy consumption returned by Load Aggregator
The resulting energy bills are used to show both the main results page, and additional report, the monthly electricity bill report, and where appropriate the TOU report, where monthly energy is displayed according to TOU bin.
Start the Aggregator process
Import DOE-2 hourly output files (the hourly heating and cooling energy consumption).
Import non-HVAC hourly load shapes (derived from California Energy Commission load shape data).
Create hourly consumption profile for non-HVAC appliances using hourly load shapes
Combine all hourly consumption files into a single whole-house hourly consumption profile.
The TOU mask file indicates the “bin” (peak, off-peak or shoulder) to which each hour’s energy consumption should be allocated. If the tariff has been used prior to this calculation, a TOU hourly will exist. If not, a mask is generated using details about the tariffs rate structure.
After applying the TOU mask, sum consumption in each bin, and find the maximum demand for the house.
