There are 2 kinds of fields associated with 60 Hz power created by electric charges. Electric fields result from their strength of the charge and magnetic fields result from the motion of the charge. Taken together they are often referred to as electromagnetic fields. There are electric and magnetic fields wherever there is electric power.

Through a master station comprised of the equipment and computer software, the EMS will provide monitoring and control of complete system status, such as electric load, voltage levels and interruptions of service. It will also provide information for sales or purchase transaction evaluations, efficient generation scheduling and generation-to-load m [..]
