Venture Global is seeking to quell accusations from major energy clients that it plans to sell liquefied natural gas cargoes on spot markets rather than honouring supply contracts from its new export terminal in Louisiana.

The US LNG supplier wrote to clients on Thursday affirming its commitment to deliver on contractual obligations, after selling more than 100 cargoes from its Plaquemines facility before having declared it operational. Such a declaration triggers legal obligations to begin delivering on contracts.

The customers are fearing a repeat of Venture Global’s conduct when it launched its first facility, Calcasieu Pass, from which it sold more than 400 cargoes on spot markets before fulfilling deliveries to customers. The move has led to growing legal and financial pressure on the group after an international arbitration panel ruled last week that the company breached its obligations.
