An apparatus for metering separate electric lighting circuits for comparative electric power usage, to provide a virtual power plant in electric power savings comprising:
- a—an electric power line to a light source in a circuit A and a switch in said electric power line to said light source in circuit A,
- b—an electric power line to a light source in a circuit B and a switch in said electric power line to said light source in said circuit B,
- c—a light meter at a distance d from direct light source of circuit A,
- d—a light meter at a distance d from direct light source of circuit B,
- e—a clamp-on ammeter and clamp of said ammeter surrounding said electric power line to said light source of said circuit A, said clamp-on ammeter connected into a computer through a probe opening in a panel of said computer,
- f—a clamp-on ammeter and clamp of said ammeter surrounding said electric power line to said light source of said circuit B, said clamp-on ammeter, of said circuit B, connected into said computer through a probe opening in said panel of said computer,
- g—a circuit A amperage reading window in said panel of said computer,
- h—a circuit B amperage reading window in said panel of said computer,
- i—a select switch in said panel of said computer, and said select switch to scan the selections of hours, volts, circuit B amperes, total amperes all fixture lights, KW rate % ratio, KW saved, amperes saved,
- j—a window in said panel of said computer to display data scanned,
- k—a voltage reset switch to switch to higher voltage and a switch to lower voltage, in said panel of said computer,
- l—a window to display power cost of said circuit A,
- m—a window to display power cost of said circuit B,
- n—a toggle switch in up position to show power cost of said circuit B in total,
- o—said toggle switch in down position to show power cost of said circuit A in total and,
- p—electric power plug in said panel of said computer, and a probe opening for communication plug-in on said panel of said computer.
