Abstract
A system and method for offsetting peak demand for a customer of an electrical utility is disclosed. The system includes a source of stored electrical energy connected between an electrical service panel and a load. Demand spikes are detected by monitoring current flowing to the load, and when a demand spike is detected, the source of stored energy is connected to the load.
Claims15
An electrical peak demand offset system, comprising:
- at least one electrical current monitor electrically connected between a service panel connection and an electrical load at an electrical utility customer;
- a source of stored electrical energy connectable to the electrical load by a switch;
- a programmable processor in electronic communication with the electrical current monitor and the switch.
An electrical peak demand offset system, connected between a service panel and an electrical load, the system comprising:
- a pass-though electrical path between the service panel and the load including an inductor;
- a switch;
- a source of stored electrical energy selectably connectable to the electrical load by the switch;
- a power input electrically connected to the service panel;
- a power output electrically connected to the load;
- a microprocessor connected to the switch by a data communications path;
- a communications interface connected to the microprocessor by a data communications path;
A method of offsetting peak electrical demand by an electrical utility customer, the method comprising:
- measuring current on an electrical connection between a load and an electrical utility;
- computing, on the basis of the current measurements, the electrical demand of the load;
- comparing the computed electrical demand to stored thresholds;
- on the basis of the comparison, connecting a source of stored electrical energy to the load.
