Sabine Pass Liquefaction LLC inked a 20-year sale and purchase agreement with a subsidiary of Malaysian state-owned energy giant Petroliam Nasional Bhd. for about 1.1 million tonnes of liquefied natural gas per year.

Under the deal, Petronas LNG Ltd. would purchase LNG on a free on board basis for a term of 20 years following the date of first delivery for the sixth train of the Cheniere Energy Partners LP unit's export facility in Cameron Parish, La., according to a Dec. 18 news release.

"This 20-year agreement with Sabine Pass Liquefaction continues our momentum on Train 6, where early engineering, procurement, and site preparation activities have recently commenced ahead of a final investment decision," said Cheniere Partners Chairman, President and CEO Jack Fusco. The deal is expected to support efforts toward making a final investment decision on the sixth train in 2019, Fusco added.

The Sabine Pass terminal has four trains in operation, with a fifth train under commissioning. The sixth train would have a production capacity of about 4.5 mtpa of LNG.
