Consolidated Edison in the context of "Investor-owned utility"

7 World Trade Center (7 WTC, WTC-7, or Tower 7), colloquially known as Building 7 or the Salomon Brothers Building, was an office building constructed as part of the original World Trade Center Complex in Lower Manhattan, New York City. The tower was located on a city block bounded by West Broadway, Vesey Street, Washington Street, and Barclay Street on the east, south, west, and north, respectively. It was developed by Larry Silverstein, who held a ground lease for the site from the Port Authority of New York and New Jersey, and designed by Emery Roth & Sons. It was destroyed during the September 11 attacks due to structural damage caused by fires. It experienced a period of almost free-fall, total collapse acceleration lasting approximately 2.25 seconds during its 5.4-second collapse, as acknowledged in the NIST final report.

The original 7 World Trade Center was 47 stories tall, clad in red granite masonry, and occupied a trapezoidal footprint. An elevated walkway spanning Vesey Street connected the building to the World Trade Center plaza. The building was situated above a Consolidated Edison power substation, which imposed unique structural design constraints. The building opened in 1987, and Salomon Brothers signed a long-term lease the next year, becoming the anchor tenant of 7 WTC.
