Patent ID: 8214270

Claim:
A method for providing an energy bill to a consumer that integrates a primary energy source and one or more renewable energy sources, said method comprising the steps of: providing at least one computing device having a microprocessor for executing computer coded instructions, said computer coded instructions including instructions for a plurality of equations that calculate attributes of an energy bill; obtaining rates that determine primary energy cost including energy demand rates, usage rates, and tax rates for predetermined time periods or consumption levels for the primary energy source; obtaining a primary energy demand and usage for the period for the primary energy source; calculating, via the computing device, a value of a primary energy bill based upon demand and usage of the primary energy source; obtaining a renewable energy demand and usage from the renewable energy source; summing, via the computing device, the renewable energy usage plus primary usage to calculate period consumption; summing, via the computing device, the period consumption over a billing period to calculate a total period consumption, wherein the total period consumption is required when a tiered billing structure is used; summing, via the computing device, the renewable demand plus primary energy demand to calculate a total demand; calculating, via the computing device, a value of a total energy bill based upon the total period consumption, the total demand, and the primary energy cost rates; calculating, via the computing device, a renewable energy bill as a difference between the total energy bill and the primary energy bill; and generating, via the computing device, an output to a consumer in the form of at least one of a billing report or user interface detailing at least one of the renewable energy bill, the total energy bill and the primary energy bill.
