Abstract

Techniques are provided for shifting residential electric load from a utility power grid to a battery system during preconfigured hours of electric use. The apparatus includes a memory configured to store computer executable instructions, and a microprocessor in communication with the memory, the microprocessor configured to execute the instructions to cause the apparatus to shift residential electric load from the utility power grid to the battery system for a first time period during a first calendar period of a calendar year, and to shift residential electric load from the utility power grid to the battery system for a second time period during a second calendar period of the calendar year.

Claims

1. A load shed apparatus for shifting residential electric load from a utility power grid to a battery system during preconfigured hours of electric use, the apparatus comprising:

a memory configured to store computer executable instructions;

a microprocessor in communication with the memory, the microprocessor configured to execute the instructions to cause the apparatus to;

shift residential electric load from the utility power grid to the battery system for a first time period during a first calendar period of a calendar year; and

shift residential electric load from the utility power grid to the battery system for a second time period during a second calendar period of the calendar year.

2. The load shed apparatus of claim 1, wherein the first time period, the second time period, the first calendar period, and the second calendar period are defined by a local electric power pool and utility.

3. The load shed apparatus of claim 2, wherein:

the first time period is 1-5 pm and the first calendar period is a summer season; and

the second time period is 5-7 pm and the second calendar period is a winter season.

4. The load shed apparatus of claim 1, further configured to control 20 amp relays to switch electric load between the utility power grid and the battery system.

5. The load shed apparatus in claim 4, wherein the microprocessor is configured to control the 20 amp relays via a MOSFET.

6. The load shed apparatus in claim 1, further configured to automatically provide emergency power for one or more of a residence heating system, a refrigerator and kitchen lights, for an emergency time period in the event of a loss of utility power.

7. The load shed apparatus in claim 6, wherein the emergency time period is 4-8 hours depending on a size of the battery system.

8. The load shed apparatus in claim 1, further configured to meter electric usage during shed and non-shed operations to generate reporting data.

9. The load shed apparatus in claim 8, further configured to:

meter the electric usage every minute individually for each of three electric circuits, wherein the three electric circuits supply power to a home HVAC system, a home refrigerator and home kitchen lights; and

sum the minute readings for each of the three individual circuits for each hour to generate hourly reporting data.

10. The load shed apparatus in claim 1, further configured to monitor the battery system for voltage, heat and hours of operation.

11. The load shed apparatus in claim 1, further comprising Ethernet circuitry to provide Ethernet communication to transmit reporting data to a remote server.
