Sounds right. Just make sure the "average" rate is the virtual rate. The virtual rate is the total kWh consumed in the model divided by the total electric cost.

The rate in the model can be entered as a simple rate $/kWh or as a complex rate with tiers, demand charges, rachets, etc. In the case of a simple rate it is the same as the virtual rate.

Yes reverse it. $/kWh is what you want..

You can use some type of average - this is the simple rate I mentioned above.

You can enter the rate schedule in the model and it will apply it to your consumption - this is the complex rate I mention above. We will generally use the actual rate in our models as this would produce a more accurate result.
