July 3 (Reuters) - Glenfarne Global Commodities announced on Friday a heads of agreement with BGN, a privately owned energy and commodities trading group, for the long-term supply of 1 million tonnes per annum of liquefied natural gas.

Glenfarne and BGN will look to negotiate a 20-year sale and purchase agreement for LNG supplied from Texas LNG, Glenfarne's LNG export project in Brownsville, Texas, according to the HOA.

Earlier this year, RWE and Glenfarne signed a 20-year supply agreement for LNG from Texas LNG, with expected commissioning in 2030. Thai oil and gas company PTT Group PTT.BK last year signed an agreement to procure 2 million tonnes of LNG per annum from Glenfarne's Alaska LNG over a 20-year term.
