that the company would invest $1.25 billion in “renewable energy production facilities over the next three years.” The company's “renewable portfolio” contains more than 1.5 gigawatts of operating capacity. Seventy-five percent of that capacity comes from solar energy. Clean energy accounts for around eight percent of the company's earnings, as of fall 2017. To support electric vehicles, Con Edison partnered with the company FleetCarma to provide $500 in rewards to owners of electric vehicles in New York City and Westchester County, New York. Through this program, Con Edison pays customers to charge their vehicles when energy demand is low. 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 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 HVDC line is expected to come online in 2025. 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 of underground cable in the Con Edison system could wrap around the Earth 3.6 times. Nearly 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 of pipes—if laid end to end, long enough to reach Paris and back to New York City, and serves Westchester County, the Bronx, Manhattan and parts of Queens. Gas service in Brooklyn, Staten Island and the rest of Queens is provided by National Grid USA's New York City operations, with the exception of the Rockaway peninsula, which is serviced by National Grid's Long Island operations. 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 before distributing it to hundreds of buildings in the New York City steam system, which is the biggest district steam system in the world.
