Wide-area electrical demand and supply management

[Subject] The system and method of the present invention monitor an electric formula and/or mechanical apparatus, and the user can be bidirectional and can change operation of apparatus distantly. Since operation of equipment can change distantly, remote adjustment of the corresponding resource consumption can also be carried out with remote control.
