Multiple dispatchable resources such as energy storage systems, generators, and curtailable loads are used to fulfill electricity usage control instructions by implementing multiple different sets of dispatch instructions. The sets of dispatch instructions vary based on individual status characteristics and aggregate status characteristics of the dispatchable resources in order to use the resources optimally. The resources may in some instances be prioritized according to their status characteristics in order to improve response efficiency, improve cost-effectiveness, reduce errors and flawed fulfillment, and improve the ability of the resources to respond to different kinds of electricity usage control instructions over time.
