Electricity travels at nearly the speed of light, arriving at a destination at almost the same moment it is produced. Unlike oil or natural gas in a pipeline, electricity cannot easily be stored. It must be generated and delivered at the precise moment it is needed. The nation’s electric distribution systems deliver power along millions of miles of lines to neighborhoods, businesses, and consumers.
How the System Works
After electricity is generated and transmitted, step-down transformers located in distribution substations reduce the voltage so it can be carried on smaller cables or distribution lines.
