Corpus Christi Liquefaction, a subsidiary of Cheniere Energy, has signed a liquefied natural gas (LNG) sale and purchase agreement with Endesa.

As part of the deal, Endesa will buy around 0.75 million tonnes per annum (mtpa) of LNG from the LNG export facility being developed near Corpus Christi of Texas, upon the commencement of operations.

Earlier, Endesa has signed an agreement with the same company to purchase about 1.5 mtpa of LNG.

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.

Cheniere Energy chairman and CEO Charif Souki said that Endesa has agreed to purchase an additional 0.75 mtpa from the Corpus Christi Liquefaction project for use by their Italian parent company Enel.

"We continue to work towards finalizing additional agreements and expect to complete all necessary steps to reach a final investment decision and begin construction by early 2015," Souki added.
