Abstract
As system is disclosed for providing power averaging for the utility grids and more specifically to utilizing a unique EESU unit with the capability to store electrical energy over 24 hour periods each day and provide power averaging to homes, commercial, and industrial sites to reduce the peak power requirements. Charging such power averaging units during the non-peak times and delivering the energy during the peak-demands times provides for more efficient utilization of utility-grid power-generating plants and the already existing power transmission lines. Such a unit may also have the capability of isolating the users from utility-grid power failures, transients, and AC noise.
