Abstract

One embodiment of the invention provides an electric power generation system. The system includes an electric power generator. A second electric meter is connected to the power generator and an electric power consumer. The second meter measures electric power generated by the power generation system. A first electric meter is connected to an electric power distribution line. The power line supplies electric power from an electric grid and receives surplus power from the power generator. Thus, the first meter measures a net electric power provided to the electric power consumer through the electric power line.

Claims

1. An electric power generation system comprising:

an electric power generator;

a second electric meter, the second meter is connected to the electric power generator and the electric power consumer, the second meter measures the electric power generated by the electric power generation system; and

a first electric meter, the first meter connected to an distribution power line, the power line supplies electric power from an electric grid and receives surplus power from the power generation system, wherein the first meter measures a net electric power provided to the electric power consumer through the power line.

2. The system of claim 1, wherein the electric power generator is a solar photovoltaic system.

3. The system of claim 1, wherein the electric power generator is a wind system.

4. The system of claim 1, wherein the electric power generator is a hydroelectric system.

5. An electric power generation system comprising:

an electric power generator;

a second electric meter, the second meter is connected to the electric power generator and either an electric grid, a utility side of a first meter, or a connection point between the first meter and a electric distribution power line, the second meter measures the electric power generated by the electric power generator; and

the first meter is connected to the electric distribution power line, the power line supplies electric power from the electric grid, and the first meter measures the electric power utilized by the electric power consumer.

6. The system of claim 5, wherein the electric power generator is a solar photovoltaic system.

7. The system of claim 5, wherein the electric power generator is a wind system.

8. The system of claim 5, wherein the electric power generator is a hydroelectric system.

9. A method of purchassing electric power from an electric power customer who generates electric power, the method comprising:

setting a price per unit amount of electric power for electric power generated by the electric power customer at a price per unit amount of electric power that exceeds a generation price per unit amount of electric power paid by the electric power customer for electric power consumed; and

purchasing the generated electric power from the electric power customer at the set price per unit amount of electric power.

10. A method of reducing a customer'"'"'s net electric power payment to an ESP or UDC, the method comprising:

providing an electric power generation system; and

selling the electric power produced by the power generation system at a price per unit of electric power that exceeds the generation price per unit amount of electric power paid by the customer for electric power consumed.

11. The method of claim 10, further comprising:

purchasing electric power at a generation price per unit amount of electric power that is below the price per unit amount of electric power received for the electric power produced by the power generation system.

12. A method of billing for electric power consumed and compensating a customer for electric power produced, the method comprising:

charging an electric power consumer a generation charge for the total electric power consumed, the generation charge determined by multiplying a first rate by the amount of electric power consumed or estimated to have been consumed; and

paying or crediting the electric power consumer a generation fee, the generation fee determined by multiplying a second rate by the amount of electric power generated or estimated to have been generated, the second rate being higher than the first rate.

13. The method of claim 12, further comprising:

charging the electric power consumer a transmission and distribution charge, the transmission and distribution charge determined by multiplying a third rate by an amount of electric power transmitted to the electric consumer or estimated to have been transmitted to the electric power consumer.

14. The method of claim 13, wherein the amount of electric power transmitted to the electric consumer or estimated to have been transmitted to the electric power consumer is the amount of electric power consumed or estimated to have been consumed reduced by the amount of electric power generated or estimated to have been generated.
