===Electrical=== The Con Edison electrical transmission system utilizes voltages of 138 kilovolts (kV), 345 kV, and 500 kV. The company has two 345 kV interconnections with upstate New York that enable it to import power from [[Hydro-Québec]] in [[Canada]] and one 345 kV interconnection each with [[Public Service Enterprise Group|Public Service Electric and Gas]] (PSE&G) in New Jersey and Long Island. Con Edison's connection with Hydro-Québec is via a series of transmission lines owned by the New York Power Authority and neighboring utilities; a more direct connection via the [[Champlain Hudson Power Express]] [[High-voltage direct current|HVDC]] line is expected to come online in 2025.<ref>{{cite web |url= http://www.chpexpress.com/about.php | title= Champlain Hudson Power Express Project Development Portal | date = 2017 | access-date= 27 March 2017 |publisher= Transmission Developers Inc.}}</ref> Con Edison is also interconnected with PSE&G via the Branchburg-Ramapo 500 kV line. Con Ed's distribution voltages are 33 kV, 27 kV, 13 kV, and 4 kV. The {{convert|93000|mi|km}} of underground cable in the Con Edison system could wrap around the Earth 3.6 times. Nearly {{convert|36000|mi|km}} of overhead electric wires complement the underground system—enough cable to stretch between New York and Los Angeles 13 times.<ref>{{cite web |url = http://www.coned.com/newsroom/energysystems_electric.asp |title = Electric System |website = Con Edison |quote = Con Edison operates one of the most complex electric power systems in the world.
