As part of the deal, Endesa will purchase around 1.5 million tonnes per annum of LNG from the LNG export facility being developed near Corpus Christi, Texas.

With aggregate design production capacity of 13.5 mtpa of LNG, the Corpus Christi Liquefaction project is being designed and permitted for up to three trains, noted Cheniere.

Upon the date of first commercial delivery and an extension option of up to ten years, the SPA has a term of 20 years, while first delivery is expected in early 2018.

Cheniere Energy chairman and CEO Charif Souki said that Endesa is the second foundation customer for Corpus Christi Liquefaction project being developed in Texas.

"We continue to work towards finalizing additional commercial agreements and are nearing completion of the regulatory process, having recently received our scheduling notice from the FERC," Souki added.
