Enron was originally involved in transmitting and distributing electricity and natural gas throughout the United States. The company developed, built, and operated power plants and pipelines while dealing with rules of law and other infrastructures worldwide. Enron owned a large network of natural gas pipelines, which stretched coast to coast and border to border including Northern Natural Gas, Florida Gas Transmission, Transwestern Pipeline company and a partnership in Northern Border Pipeline from Canada. The states of California, New Hampshire, and Rhode Island had already passed power deregulation laws by July 1996, the time of Enron's proposal to acquire Portland General Electric corporation. During 1998, Enron began operations in the water sector, creating the Azurix Corporation, which it part-floated on the New York Stock Exchange during June 1999. Azurix failed to become successful in the water utility market, and one of its major concessions, in Buenos Aires, was a large-scale money-loser.
