Abstract

An apparatus comprises at least one energy storage system, at least one switchgear assembly configured to be attached to a utility electrical line, the at least one switchgear assembly connected to the at least one energy storage system, at least one sand source configured to house a granular material, a blender configured to mix the at least one granular material with water from a water source, the blender further configured to send the at least one granular material with water to an electric pump, the blender connected to the at least one switchgear assembly, and an electric pump configured to pump the at least one granular material with water to a wellbore, the electric pump connected to the at least one switchgear assembly.

First claim

What is claimed is:

1. An apparatus, comprising:
at least one energy storage system;
an electric vehicle charging station;
at least one switchgear assembly configured to be attached to a utility electrical line, wherein the at least one switchgear assembly is connected to the at least one energy storage system and the electric vehicle changing station;
at least one sand source configured to house a granular material;
a blender configured to mix the granular material with water from a water source, and send the granular material with water to an electric pump, and wherein the blender is connected to the at least one switchgear assembly; and
an electric pump configured to pump the at least one-granular material with water to a wellbore, wherein the electric pump is connected to the at least one switchgear assembly.

2. The apparatus according to claim 1 , wherein the at least one switchgear assembly is disposed on a trailer.

3. The apparatus according to claim 1 , wherein the at least one energy storage system is comprises two energy storage systems.

4. The apparatus according to claim 1 , further comprising:
a granular moving system configured to move granular material to the blender, wherein the granular moving system is connected to the at least one switchgear assembly.

5. The apparatus according to claim 4 , wherein the granular moving system comprises a conveyor.

6. The apparatus according to claim 1 , further comprising:
at least one solar array connected to the at least one switchgear assembly.

7. The apparatus according to claim 1 , wherein the at least one energy storage system comprises a battery system.

8. The apparatus according to claim 7 , further comprising:
a battery management system connected to the battery system, wherein the battery management system is configured to manage at least one property of the battery system.

9. The apparatus according to claim 1 , wherein the at least one switchgear assembly is connected to the at least one energy storage system via a split-phase inverter.

10. A method of hydraulic fracturing, comprising:
providing an electrically operated hydraulic fracturing system comprising a switchgear assembly, a pump connected to the switchgear assembly, and an electric vehicle charging station connected to the switchgear assembly;
connecting the switchgear assembly to a utility based power grid;
obtaining electricity from the utility based power grid;
charging an electric vehicle using the electric vehicle charging station; and
performing a hydraulic fracturing operation using pump.

11. The method according to claim 10 , further comprising:
transforming the obtained electricity from the utility based power grid prior to the performing of the hydraulic fracturing operation.

12. The method according to claim 10 , further comprising:
storing the electricity in an energy storage system, prior to the performing of the hydraulic fracturing operation.

13. The method according to claim 12 , further comprising:
generating electricity through a solar cell system prior to the performing of the hydraulic fracturing operation.

14. The method according to claim 13 , further comprising:
transforming the electricity generated by the solar cell system prior to the storing of the electricity in the energy storage system.

15. A method of conducting an electric hydraulic fracturing-operation, comprising:
providing an electrically operated hydraulic fracturing system comprising a switchgear assembly, a pump connected to the switchgear assembly, and an electric vehicle charging station connected to the switchgear assembly;
connecting the switchgear assembly to a micro-power grid;
obtaining electricity from the micro-power grid;
charging an electric vehicle using the electric vehicle charging station; and
performing a hydraulic fracturing operation using the pump.

16. The method according to claim 15 , further comprising:
transforming the obtained electricity from the micro-power grid prior to the performing of the hydraulic fracturing operation.

17. The method according to claim 15 , further comprising:
storing the electricity in an energy storage system, prior to the performing of the hydraulic fracturing operation.

18. The method according to claim 17 , further comprising:
generating electricity through a solar cell system prior to the performing of the hydraulic fracturing operation.

19. The method according to claim 18 , further comprising:
transforming the electricity generated by the solar cell system prior to the storing of the electricity in the energy storage system.
