Origin Energy Limited
(ASX:ORG) has inked a gas supply agreement with Esso Australia Resources and BHP Billiton Limited
(ASX:BHP).
Origin says supply will start next year and annual contract volumes would increase over the nine-year period.
Origin Energy markets chief executive officer Frank Calabria says the demand for natural gas on Australia's east coast remains robust and the deal allows Origin to sell long-term contracts to meet customers' needs.
The deal is worth more than $3 billion, according to media reports.
Origin Energy generated a net profit of $378 million in fiscal 2013.
