HOUSTON: Exxon Mobil Corp is suing Australia's Macquarie Energy in a Texas court in a US$11.7 billion lawsuit over missed deliveries during last month's winter freeze in the central United States.
The lawsuit filed by Exxon's natural gas business said the massive storm and state declarations of emergencies prevented it from fulfilling its supply commitment to Macquarie Energy, the second largest U.S. gas marketer.
Exxon is asking the Texas court to rule that the massive storm, caused when an arctic air mass swept the central United States, was a natural disaster.
Such a ruling would allow Exxon to break its contract with Macquarie without a penalty, overriding a demand from the Australian company that Exxon cover the wholesaler's US$11.7 billion in damages for missed deliveries.
U.S. gas demand and prices soared last month when freezing temperatures hit as far south as Texas, where 4.3 million homes lost power.
A Macquarie spokesperson in Australia declined immediate comment. Exxon did not reply to a request for comment after normal business hours.
The cold sent spot gas at a west Texas hub to US$203.50 per million British thermal units (mmBtu) on Feb. 16. It also prompted Texas and Louisiana to declare emergencies and direct gas supplies to the states' power generators.
Australia's Macquarie was one of the largest winners in the cold snap, benefiting from record U.S. natural gas prices. It could collect a US$317 million profit from a weather related gas binge, analysts said.
Macquarie had rejected Exxon's own declaration of a natural disaster, the lawsuit said, but the Australian company later issued its own force majeure declaration over gas it had agreed to provide Exxon in Texas.
