BG announced it signed a 20-year sale and purchase agreement with Sabine Gas Liquefaction, a subsidiary of Cheniere Energy Partners, for 3.5 million tons of liquefied natural gas a year from terminals in Louisiana.
"This is a ground-breaking agreement for BG Group, giving us first-mover advantage in securing LNG export volumes from the U.S. Gulf Coast," BG Group Chief Executive Frank Chapman said in a statement.
"It is the first agreement of its kind in this region and it secures us early access to the rapidly emerging commercial opportunities driven by the recent material increases in U.S. gas reserves."
BG Group added it won approval from the U.S. Department of Energy to export around 730 billion cubic feet of natural gas from an LNG terminal in the U.S. South to countries that have free trade agreements with the United States.
Lower gas prices in the United States create a commercial opportunity for BG Group.
Construction for Sabine Pass LNG facilities begins next year. Exports should start in 2015.
