June 10 (Reuters) - Cheniere Energy, the largest

liquefied natural gas exporter in the U.S., has applied to the

Federal Energy Regulatory Commission for permission to expand

its Sabine Pass plant, according to a FERC document.

Cheniere filed a joint application, dated June 6, to FERC

for authorization to construct and operate the Sabine Pass Stage

5 Expansion Project, which would grow the existing Sabine Pass

LNG facility in Louisiana.

The Sabine Pass terminal, with an annual capacity of 30

million metric tonnes per annum (mtpa), is the largest LNG

terminal in the U.S. with six liquefaction trains in service.

The proposed expansion will include an addition of three

natural gas liquefaction trains, each with a maximum LNG

production capacity of about 300 billion cubic feet per year,

the FERC document showed.

Cheniere Chief Executive Officer Jack Fusco said in February

that the company plans to aggressively pursue new regulatory

permits to expand capacity now that U.S. President Donald Trump

is in office.

On Trump's first day in office, he declared an energy

emergency and restarted approvals for LNG export permits to

countries without a free trade agreement with the U.S.
