The project, located in Corpus Christi, Texas, can now export up to 2.1 billion standard cubic feet per day of natural gas for 20 years.
“The development of U.S. natural gas resources is having a transformative impact on the U.S. energy landscape, helping to improve our energy security while spurring economic development and job creation around the country,” the Energy Department said.
Corpus Christi Liquefaction is a subsidiary of Houston-based Cheniere Energy and will include three trains with an expected aggregate nominal production capacity of up to 13.5 million tonnes per year.
Last week the Energy Department granted final approval to Dominion Cove Point LNG to export LNG to countries that do not have a Free Trade Agreement with the United States for 20 years.
The U.S. Energy Information Administration is forecasting domestic gas production to hit a record breaking 72.4 billion cubic feet per day in 2015.
