The US Federal Energy Regulatory Commission has approved the construction of Venture Global's proposed $8.5 billion Plaquemines liquefied natural gas export facility in Louisiana.

Ferc also approved the Gator Express natural gas pipeline system to deliver feed gas to the terminal, which has a nameplate capacity of 20 million tonnes per annum.

The commission attached to its authorisation a range of conditions, including facility staff training and filing additional information, that were recommended in the final environmental impact statement for the terminal which was issued earlier this year.
