About National Grid
History
National Grid originated from the restructurings of the UK gas industry in 1986 and the UK electricity industry in 1990. We entered the US electricity delivery market in 2000 in New England and expanded into upstate New York in 2002. We substantially increased our UK wireless infrastructure activities in 2004. In 2005, following the sales of four UK regional gas distribution networks, we adopted National Grid as a single name for all our principal businesses. In 2006, we acquired from Southern Union Company its gas distribution network in Rhode Island and announced the proposed acquisition of KeySpan, expanding our interests in the US. In April 2007 we completed the sale of our UK wireless infrastructure business and agreed to the sale of our US wireless infrastructure operations, with completion expected later in 2007. We also remain committed to the sale of the Basslink electricity interconnector in Australia, in line with our strategy to focus on our core energy infrastructure markets in the UK and the US.
