1. An apparatus for controlling demand on a power grid from a load facility in response to a demand event, the load facility including electrical devices that are powered from power drawn from the power grid, the apparatus comprising:
a memory configured to store computer-readable program code; and
a processor configured to access the memory, and execute the computer-readable program code to cause the apparatus to at least:
define a plurality of resources of the load facility based on user input, each resource including one or more of the electrical devices and one or more measures to reduce power consumption of the one or more of the electrical devices to decrease demand on the power grid;
establish a response strategy for the demand event, including:
select resources from the plurality of resources to respond to the demand event; and
organize the resources into the response strategy that specifies the resources and times during the demand event at which the resources are called to execute the one or more measures to reduce the power consumption of the one or more of the electrical devices to decrease demand on the power grid, different ones of the resources called at different times during the demand event, and at least one of the resources called to execute the one or more measures for a duration that is shorter than the demand event; and
execute the response strategy to reduce demand on the power grid from the load facility during the demand event.
 
15. A method of controlling demand on a power grid from a load facility in response to a demand event, the load facility including electrical devices that are powered from power drawn from the power grid, the method comprising:
defining a plurality of resources of the load facility based on user input, each resource including one or more of the electrical devices and one or more measures to reduce power consumption of the one or more of the electrical devices to decrease demand on the power grid;
establishing a response strategy for the demand event, including:
selecting resources from the plurality of resources to respond to the demand event; and
organizing the resources into the response strategy that specifies the resources and times during the demand event at which the resources are called to execute the one or more measures to reduce the power consumption of the one or more of the electrical devices to decrease demand on the power grid, different ones of the resources called at different times during the demand event, and at least one of the resources called to execute the one or more measures for a duration that is shorter than the demand event; and
executing the response strategy to reduce demand on the power grid from the load facility during the demand event.
