Benefits of Utility Bill Analysis

Refunds from errors• Wrong date, wrong reads, wrong rate, etc.

Refunds from optimum rates• Real-time pricing vs. regular pricing• Adders, etc.• Equipment improvements that lower demand

should change rates – electric CBL (customer base load)

• Many utility companies have rate departments

4

Benefits of Utility Bill Analysis

Refunds from incorrect calculations or misapplication of taxes, especially if the company is government or a non‐profit Benefits can be gained from all utilities

• Water, natural gas, and electricity• You should not pay sewage for irrigation
