1. A method of controlling electrical power delivery to a well tool, the method comprising:

  • broadcasting light through an interrogator, wherein the interrogator comprises a photo-detector;

    converting light energy to electrical energy in a well;

    storing the electrical energy downhole in an electrical energy storage device;

    then transmitting a trigger light via an optical waveguide to a circuit in the well;

    closing the circuit with the trigger light to release the electrical energy downhole from the electrical energy storage device; and

    the circuit delivering the stored electrical energy to the well tool in response to the circuit receiving the trigger light.
