Technology's Strategic Role
The electric utility industry is undergoing its most profound change since Thomas Edison and George Westinghouse battled over whether the American power system should be AC or DC. In essence, that technological choice shaped the industry we know today. Edison's low-voltage, DC system would have required many small generating stations and short distribution lines. The high-voltage Westinghouse AC system promoted development
of long-distance transmission networks that deliver electricity efficiently from large, remote power plants.
