Systems
- Electrical
The Con Edison electrical transmission system utilizes voltages of 138,000 volts, 345,000 volts and 500,000 volts. The company has two 345kv interconnections with upstate New York that enable it to import power from Hydro-Québec in Canada and one 345kv interconnection each with Public Service Electric and Gas in New Jersey and LIPA on Long Island. Con Edison is also interconnected with Public Service Electric and Gas via the Branchburg-Ramapo 500,000 volt line. Con Ed's distribution voltages are 33,000; 27,000 and 13,800 volts.
The 93,000 miles (150,000 km) of underground cable in the Con Edison system could wrap around the Earth 3.6 times. Nearly 36,000 miles (58,000 km) of overhead electric wires complement the underground system—enough cable to stretch between New York and Los Angeles 13 times.
- Gas
The Con Edison gas system has nearly 7,200 miles (11,600 km) of pipes – if laid end to end, long enough to reach Paris and back to New York City. The average volume of gas that travels through Con Edison’s gas system annually could fill the Empire State Building nearly 6,100 times.
- Steam
Con Edison produces 30 billion pounds of steam each year through its seven power plants which boil water to 1,000°F (538°C) before pumping it to hundreds of buildings in the New York City steam system, which is the biggest district steam system in the world. Steam traveling through the system is used to heat and cool some of New York’s most famous addresses, including the United Nations complex, the Empire State Building, and the Metropolitan Museum of Art.

Famous quotes containing the word systems:
“What is most original in a man’s nature is often that which is most desperate. Thus new systems are forced on the world by men who simply cannot bear the pain of living with what is. Creators care nothing for their systems except that they be unique. If Hitler had been born in Nazi Germany he wouldn’t have been content to enjoy the atmosphere.”
—Leonard Cohen (b. 1934)
“In all systems of theology the devil figures as a male person.... Yes, it is women who keep the church going.”
—Don Marquis (1878–1937)
“Our little systems have their day;
They have their day and cease to be:
They are but broken lights of thee,
And thou, O Lord, art more than they.”
—Alfred Tennyson (1809–1892)
