Abstract

A plurality of power generating assets are connected to a power grid. The grid may, if desired, be a local grid or a utility grid. The power grid is connected to a plurality of loads. The loads may, if desired, be controllable and non-controllable. Distribution of the power to the loads is via a controller that has a program stored therein that optimizes the controllable loads and the power generating assets. The optimization process is via multi-tier benefit construct.
