The system tracks the amount of electrical energy produced by the energy producing asset and also tracks an amount of electrical energy used by each individual unit. The system compares energy production information including pairs of an amount of energy produced and a corresponding time interval during which the amount of energy was produced to energy usage information including pairs of an amount of energy used and a corresponding time interval during which the amount of energy was used. The system allocates an amount of energy produced during each time interval to the individual units based on the amount of energy consumed by each respective individual unit during the time intervals. The system also calculates an energy cost allocation for each individual unit. ## Claims ### Claim 1 A virtual grid system for a plurality of units at a location, comprising: a computer system in electrical communication with energy usage readers, each energy usage reader measuring energy use by an associated unit of the plurality of units;
