US liquefied natural gas developer NextDecade has reached a deal to supply LNG from its Rio Grande project in Texas, in the US, to Portugal’s Galp Trading for 20 years.

Galp will purchase 1 million tonnes per annum of LNG free on board exported from the Rio Grande project in Brownsville, with the price indexed to the Henry Hub indicator.

NextDecade is developing the Rio Grande project, for which it is aiming to take the final investment decision for the initial three liquefaction trains in the first quarter of 2023.
