Con Edison operates one of the most complex electric power systems in the world. It is also the world's most reliable.

Con Edison delivers electricity to more than 3 million customers through a huge transmission and distribution network. The company has built the world's largest system of underground electric cables to accommodate the congested and densely populated urban area it serves. The system features approximately 94,000 miles of underground cable. Con Edison's nearly 34,000 miles of overhead electric wires complement the underground system.

Annual electric usage reaches almost 55 billion kilowatt hours in Con Edison's service area. Electricity accounts for about 75 percent of Con Edison's total revenues.

Deregulation required the restructuring of New York's electric power industry, and of Con Edison. The company divested most of its electric generating capacity. Con Edison now relies on buying wholesale power from other suppliers. Industry and corporate restructuring has had little effect on Con Edison's extensive transmission and distribution system. Customers, however, can now choose from a number of suppliers, to purchase their electricity, which Con Edison will continue to deliver.
