US liquefied natural gas exporter Freeport LNG has filed a request with the US Federal Energy Regulatory Commission (Ferc) seeking a 26-month extension to build its fourth liquefaction train, citing continued delays caused by the Covid-19 pandemic.

The Texas-based facility initially received permission to begin construction on the fourth train and related infrastructure in May 2019.

In September 2020, Ferc granted the project an extension on construction to May 2026.

Freeport LNG’s legal representatives on 16 May 2022 asked in a letter to the regulator for a 26-month extension in order to complete Train 4 — from 16 May 2026 to 1 August 2028.
