How it started
Origins
The company was created in 1997 when British Gas plc divested Centrica and became BG plc, which was reorganised in 1999 as BG Group plc.
2000 to 2016
On 23 October 2000, a further demerger separated the company into Lattice Group and BG Group. Lattice took ownership of Transco (the gas transporter for the UK), Advantica (gas engineering and consultancy specialist) along with the property and transport companies and BG Group took ownership of gas fields and other assets. In 2002, Lattice merged with National Grid Company to become National Grid Transco which was renamed National Grid in 2005.
In September 2007, BG Group delisted its ADRs from the New York Stock Exchange. Instead its shares began trading on the US over-the-counter market.
In June 2008, BG Group made a US$13.1 billion bid to acquire Origin Energy, Australia's largest coal-seam gas producer, but were outmanoeuvred by ConocoPhillips, who offered to invest US$9.1 billion in a joint venture with Origin. However, in October 2008, BG Group bought Queensland Curtis LNG for US$3.4bn in order to operate in Asia's liquefied natural gas market, and on 1 November 2010, BG Group announced plans to invest £9.3bn on the world's first project to liquefy and ship gas produced from coal deposits – the first in a series of "coal seam methane" projects in the region of eastern Australia; by late 2014, this was sending gas produced from coal deposits by pipeline to a terminal in Gladstone on the east coast. In October 2011, BG Group signed a US$8 billion deal with Cheniere Energy to export liquefied natural gas from the United States.
