"war of currents", there were more than 30 companies generating and distributing electricity in New York City and Westchester County. But by 1920 there were far fewer, and the New York Edison Company (then part of Consolidated Gas) was clearly the leader. In 1936, with electric sales far outstripping gas sales, the company incorporated and the name was changed to Consolidated Edison Company of New York, Inc. The years that followed brought further amalgamations as Consolidated Edison acquired or merged with more than a dozen companies between 1936 and 1960. Con Edison today is the result of acquisitions, dissolutions and mergers of more than 170 individual electric, gas and steam companies. Consolidated Edison acquired land on the Hudson River in Buchanan, NY, in 1954 for the Indian Point nuclear power plant. The first reactor (Indian Point 1) began generating power on September 16, 1962. The reactor was shut down on October 31, 1974, because the emergency core cooling system did not meet regulatory requirements. The company built two more reactors at Indian Point during the 1970s: Indian Point 2 and 3. Indian Point 3 was sold to the New York Power Authority in 1975. Entergy acquired Indian Point 2 in November 2000, nine months after a steam generator leak. With the sale of Indian Point 2, the last power plant it owned, Consolidated Edison, Inc. became primarily an energy distributor. On January 1, 1998, following the deregulation of the utility industry in New York state, a holding company, Consolidated Edison, Inc., was formed. It is one of the nation's largest investor-owned energy companies, with approximately $13 billion in annual revenues and $47 billion in assets. The company provides a wide range of energy-related products and services to its customers through two regulated utility subsidiaries and three competitive energy businesses. Under a number of corporate names, the company has been traded on the NYSE without interruption since 1824—longer than any other NYSE stock. Its largest subsidiary, Consolidated Edison Company of New York, Inc., provides electric, gas and steam service to more than 3 million customers in New York City and Westchester County, New York, an area of with a population of nearly 9 million. Also in 1998, Consolidated Edison, Inc. acquired Orange & Rockland Utilities, which is operated separately.
