The Indian importer has 20-year deals to buy 5.8 million tonnes a year of U.S. LNG, split between Dominion Energy's Cove Point plant and Cheniere Energy's Sabine Pass site.
It has offered three cargoes on a free-on-board (FOB) basis from Sabine Pass for second-half January, second-half July and first-half November loading, the sources said.
The tender closes on Jan. 22. (Reporting by Jessica Jaganathan; Editing by Tom Hogue)
