bill type

A specific type of utility bill, such as Gas - Natural, Gas - Propane, Electric, Water, and Sewer.

You are free to use different bill types for tracking various utilities and may define new bill types and enter bill data accordingly. However, for weather model calculations, the bill's bill type and the building’s (bl table record) heating or cooling utility type must be “ELECTRIC”, “GAS – NATURAL”, or “GAS - PROPANE.” These are the only utility types recognized by the out-of the-box code. If you add other bill types be aware that you would need to modify the code to perform weather model calculations.
