Freeport LNG now expects the first liquefaction train to enter service around Sept. 1, 2019, with the second and third trains seen in service around Jan. 1 and May 1, 2020, respectively, said Zdenek Gerych, a spokesman at Freeport.

Previously, the three trains under construction had been expected to enter service between fourth-quarter 2018 and the final quarter of 2019.

Each train will have the capacity to liquefy about 0.7 billion cubic feet (bcf) per day of gas. One bcf is enough gas to supply about 5 million U.S. homes for a day.

The reasons for the delay were undetermined at this point and under investigation, Gerych said.

S&P Global Platts said the delay stemmed from flooding of some yards where equipment was stored during Hurricane Harvey, which triggered massive flooding in the Houston area in August 2017.

Freeport is building its facility on Quintana Island, about 67 miles south of Houston on the Gulf Coast.

A consortium of Chicago Bridge & Iron Co NV (CB&I), Zachry Group and Chiyoda Corp. are building the Freeport facility, with CB&I leading the project.

Freeport has 20-year use-or-pay contracts to supply LNG to Osaka Gas Co Ltd and JERA—an alliance between Japanese power companies Tokyo Electric Power Co Holdings Inc and Chubu Electric Power Co Inc—from Train 1, BP Plc. from Train 2 and Toshiba Corp and South Korea’s SK E&S from Train 3.

In addition, Freeport was still developing Train 4 at the facility, which could enter service in 2023 or 2024 if the company’s marketing efforts go well, Gerych said.
