Dynamic switching between an energy source and stored energy for a dominant load

A non-transitory computer-readable storage medium for use with a computer system, wherein the non-transitory computer-readable storage medium stores program instructions that, when executed by the computer system, cause the computer system to perform operations comprising:

• determining or estimating a price of electricity, a carbon intensity of electricity, or both;
• and
• when the price of electricity, the carbon intensity of electricity, or both, exceeds a threshold, instructing a first switch in switches or electrically connected to a reversing contactor to electrically decouple a dominant load at the location from an external power source and instructing a second switch at the location or the first switch electrically connected to the reversing contactor to electrically couple the dominant load to an energy storage device at the location, wherein the dominant load has a largest power consumption at the location,
• wherein the threshold comprises a dynamically determined threshold, and
• wherein the dynamically determined threshold is based at least in part on a regional demand in a power grid, a carbon intensity of the power grid, or an available regional supply in the power grid.

A method for managing switches, comprising:

• by a computer system:
• determining or estimating a price of electricity, a carbon intensity of electricity, or both;
• and
• when the price of electricity, the carbon intensity of electricity, or both, exceeds a threshold, instructing a first switch in the switches or electrically connected to a reversing contactor to electrically decouple a dominant load at the location from an external power source and instructing a second switch at the location or the first switch electrically connected to the reversing contactor to electrically couple the dominant load to an energy storage device at the location, wherein the dominant load has a largest power consumption at the location,
• wherein the threshold comprises a dynamically determined threshold, and
• wherein the dynamically determined threshold is based at least in part on a regional demand in a power grid, a carbon intensity of the power grid, or an available regional supply in the power grid.
