power bill rates computation: customer billing sample

Below is the sample computation of a non-firm customer with motor loads. I will not include the taxable service, non-taxable service and franchise tax computations so that power bill computations will be presented as simple as possible. There are also other charges that are not included like the metering charge, force majeure charge, power factor adjustment charge, the reactive power support charge, and universal charges.
These charges are not included since I have no rates available as of this moment. The universal charges like the missionary electrification and rehabilitation and maintenance of watershed charges are also omitted since the transmission lines involved are privately-owned. In the computation table, the maximum demand was considered for the entire billing charge since the customer is a non-firm customer. For the power factor and reactive power support charges, our standard power factor is 0.90. If the customer can maintain this power factor or even better, no charges will be imposed to their monthly billing.

Sample computation:
