Controllable energy utilization system and associated method
First Claim
1. A system, comprising:
- an energy storage system configured to supply electrical energy to a first load during a single period that is defined as one of a peak period or a non-peak period and to a second load during the other of the peak period or the non-peak period; and
a system controller that is operable to maintain the energy storage system at a plurality of minimum capacity levels, wherein the minimum capacity levels include a first amount of stored electrical energy during a first mode, and a second amount of stored electrical energy during a second mode, andwherein the system controller maintains the energy storage system in the first mode during a first portion of the single period in which the first load is supplied with electrical energy by the energy storage system, and in the second mode during a second portion of the same single period, andwherein the first mode stores a minimum capacity level sufficient to power a determined demand load and an additional capacity, and the second mode stores only the minimum capacity level to power the determined demand load.

Abstract
A system includes an energy storage system capable of receiving electrical energy from an energy source and can supply electrical energy to a first load during a first period and to the first load during a second period. The first load differs in usage rate from the first period relative to the second period. A system controller maintains the energy storage system such that the energy storage system maintains a first amount of stored electrical energy during a first mode, and a second amount of electrical energy during a second mode. The system controller maintains the energy storage system in the first mode during a first portion of the first period, and in the second mode during a second portion of the first period.
