The New York Steam Company began providing service in lower Manhattan in 1882. Today, Con Edison operates the largest district-energy steam system in the United States.
The system contains approximately 105 miles of mains and service pipes and 3,000 steam manholes.
Steam is provided to our customers from five Con Edison steam-generating plants, three in Manhattan, one in Queens, and one in Brooklyn, along with receiving steam under contract from a steam plant at the Brooklyn Navy Yard.
Steam traveling through Con Edison's system is used to heat and cool some of New York's most famous addresses – the United Nations complex, the Empire State Building, and the Metropolitan Museum of Art are just a few.
Con Edison's steam system provides service to approximately 1,800 customers in Manhattan, from the Battery all the way to 96th Street on the West Side and 89th Street on the East Side.
Our commercial and residential customers use steam for heating, hot water, and air conditioning.
The winter peak sendout is nearly 10 million pounds per hour.
Steam sales account for about 6 percent of Con Edison's operating revenues.
Con Edison is the first utility to receive the System of the Year award twice, in 2000 and in 2007, from the International District Energy Association.
