In the UK, the Central Electricity Generating Board (CEGB) was created in 1957 to manage the generation and transmission of electricity in England and Wales. In 1990, under the laws of deregulation, this entity was broken up into 3 electricity generating companies, and 1 transmission company called National Grid. In 2002, National Grid merged with the UK gas distribution business to become a Transmission and Distribution business. Previously that year, National Grid acquired Niagara Mohawk, one of the New York State utility companies. In 2006, National Grid acquired KeySpan, a gas distributor in the US, as well as the New England Gas Company in Rhode Island, which doubled National Grid's size in the US, making it one of the biggest utility companies in the US.
